What happens in the Motherland stays in the Motherland

Tomorrow I am taking my first trip to Poland, which is the country where all my grandparents were born.* (Hence, I guess it's the Grandmotherland rather than the Motherland.) I am going to be an instructor in a mathematical modelling week in Wroclaw, which is not pronounced in a manner anywhere close to how it's spelled and which alas is nowhere close to any of the places where my grandparents are from. Because I am an instructor, and apparently need to be present both with my students and in meetings simultaneously during a couple of the days (I still haven't figured out how I'm going to manage this), escaping for a day to check those places out is not even remotely an option. Hopefully I'll be able to do that on another occasion, but I already some some interesting facts just by getting the names of places and looking them up on wikipedia, so I'll check things out in more detail online later. I'm hoping that maybe I'll be able to get some good latkas, kreplach, and matzah ball soup while I'm in Poland. :) We shall see.

Also, Poland will become the 8th different European country that I have visited (counting Ireland and Great Britain as European countries, because to an American they are such). I have invitations to visit Belgium and Germany, so those are the most likely candidates for me to visit next. (I also have an invitation to visit Singapore, though I'll really need to think about what timing will be good for that visit and I'd like to try to drop by and hang with friends even though the invitation is an academic one. Hence, there is some nontrivial coordination involved. The invitation to Belgium is also academic, and I have both academic and non-academic invitations for Germany.) Belgium will mostly like be the next country overall because the discussed plan was to try to get there this fall.

* Some of the places where they were born are no longer actually part of Poland.

Scurvy Cubs

It's official. The Chicago Cubs are being sold to a family by the name of Ricketts. I checked wikipedia quickly to see if it was the same family after whom the Hovse was named, but the signs seem to point to 'no' on this one. Note that my research was nowhere near what one might construe as thorough.

Human Cooker: Order now at Sears

Surely, this is somebody's idea of a practical joke, right? Right?

In case the Sears website in question gets altered or removed (and I'm guessing it probably will, as there will likely be some serious fallout), the top left of the page has the following tree to get to the page above: "Human Cooking > Grills to Cook Babies and More > Body Part Roaster"

I think somebody's head is going to roll (and then maybe be cooked with this thing)...

(Tip of the cap to Scott Porter.)

Flowchart for "Total Eclipse of the Heart"

Wow! This is just awesome! (It's also "awesome"!). The Huffington Post has posted a flowchart for the song "Total Eclipse of the Heart". Now I want to make one for certain other songs...

(Tip of the cap to Mariano Beguerisse Díaz.)

P.S. I know I have been posting a lot during the past few days, but there have been a bunch of quick things I wanted to mention. Rest assured, I will make up for this with a lower posting frequency later. :)

High School interventions

Here's the straight line (you provide the joke): My high school is adding "intervention periods" to its class schedule starting this fall.

(If you're interested, you can find the article about Beverly High's new fall bell schedule on the upper left of page 3 of the new issue of Beverly Hills Weekly.)

"Awesome" online security code

I was buying tickets to the February 20th 2010 Depeche Mode concert in London---Oh, Hell yes!!!!! (and the set lists for most of the concerts on this tour have even included both "It's No Good" and "Strangelove", which I really want to hear live and often aren't included on DM concert set lists these days!)---and the online security code to confirm that I was a human were particularly "awesome" (and maybe even awesome) on this occasion: "$10-billion castrate".

Now I just have to wait 6 months for the concert (which I'll be attending with a couple of friends)...

Dodgers sign Vicente Padilla

In an attempt to help address our continually-exacerbating starting pitching woes, the Dodgers have signed Vicente Padilla, who was recently released by the Rangers. Padilla is a warm body and can be useful given the situation, but I'd really like to do better than this. For example, I wouldn't mind if we pay a bit of money and rent someone like Aaron Harang. We have not been playing very well lately, and we need to do something about the pitching---especially if we actually want to go far in the postseason. We were coasting for a while, but I definitely don't feel as secure now as I did earlier in the season.

Dynamic communities in multichannel data: An application to the foreign exchange market during the 2007–2008 credit crisis

The title of this article, which was just officially published today, is a bit of a mouthful. This paper is the first foray by my research group into financial networks. We posted its sequel, which has a lot more detail and examples, on the arXiv in May. We don't have referee reports for that one yet, which we submitted to SIAM's new financial mathematics journal (and will give quite a different audience from Chaos, which is where the shorter paper appears). There will definitely be more of this from my group in the future, as D.Phil. student Dan Fenn (who did the heavy lifting on the paper) continues to produce excellent work and a new D.Phil. student (Martin Gould) will be starting to work on financial networks with my collaborators and me beginning September 1st.

Here is the author list for the short paper: Daniel J. Fenn, Mason A. Porter, Mark McDonald, Stacy Williams, Neil F. Johnson, and Nick S. Jones

Here is the abstract: We study the cluster dynamics of multichannel (multivariate) time series by representing their correlations as time-dependent networks and investigating the evolution of network communities. We employ a node-centric approach that allows us to track the effects of the community evolution on the functional roles of individual nodes without having to track entire communities. As an example, we consider a foreign exchange market network in which each node represents an exchange rate and each edge represents a time-dependent correlation between the rates. We study the period 2005–2008, which includes the recent credit and liquidity crisis. Using community detection, we find that exchange rates that are strongly attached to their community are persistently grouped with the same set of rates, whereas exchange rates that are important for the transfer of information tend to be positioned on the edges of communities. Our analysis successfully uncovers major trading changes that occurred in the market during the credit crisis.

Baseball Injury Cover-Ups

Jerry Crasnick writes about some baseball injury cover-ups. I'm not sure how he got through this article without mentioning Chris Brown's "sore tooth" or the injuries that Glenallen Hill sustained while apparently battling spiders during a nightmare. (Skip Carey often harped on the Hill incident, invariably bringing it up whenever the Braves faced a team that included Hill.)

Science Tattoos

Here is a blog entry on Accidental Mysteries about science tattoos

I have seen Schrödinger's equation a couple of times, and there was that infamous incident involving some Tech grad students that included one person with such a tattoo. Also, one of my undergrad researchers from Tech has a 5-clique tattoo.

MIT Technology Review's Young Investigators (TR35) for 2009

MIT Technology Review has released its list of 35 investigators under 35 for 2009. Among the list is a very familiar name: Ellis Meng, a Lloydie from the class of 1997. Congrats!

Another familiar name is a Santa Fe Institute postdoc (Nathan Eagle), who I have either met or seen speak. (I don't remember whether I talked to him.) He's one of the people doing interesting things with mobile phone data.

Quote of the Day

Today's quote comes from an anonymous referee who wrote the tie-breaking referee report that caused a paper of mine to be accepted for publication:

While this manuscript is not a perfect or complete solution to the problem of community detection in networks...

You know, it's a good thing that such a perfect or complete solution of the problem of community detection (some formulations of which have been proven to NP complete --- that is, with an appropriate definition of community based on optimizing a particular class of quantities) isn't what's expected for publication. If so, I'd have only one answer: Good luck with that.

Anyway, the referee was perfectly fair and is completely correct with the implied comment that our paper doesn't blow the problem wide open but rather just makes a specific set of interesting contributions, but I was nevetheless somewhat amused by the use of that phrasing. Perhaps that comment was simply for the benefit of the editor who works in another research area? Presumably so, but I was amused nonetheless, and I wanted to share my amusement.

My wireless printer/scanner/copier is set up!

I bought my first printer ever when I purchased my new computer last month. In my immense laziness, I only set it up today. The printer isn't exactly fast, but it is nice to finally have one at home. I'll also be upgrading my computer desk soon, as Somerville is putting some furniture into storage, and the items in question include a couple of desks that are better than mine. I used the ad hoc wireless network option to set up the printer. For now, I am calling the network "Astral" and the printer "Styx", though that goes better with previous themes than with current ones. (Back in the day, the airport network that I briefly set up was "Phlogiston"---that's for all you Spelljammer aficionados out there---but I haven't bothered setting up my airport base station for many years. Maybe one of these days, I'll bother putting my Wii online. :) )

Quote of the Day: Bulwyer-Lytton edition

Today's quote comes from the curator of the Bulwer-Lytton fiction contest: "Your submission has arrived and will receive the treatment it deserves." (I guess such comments can also apply to submissions to scientific journals.)

For what it's worth, I was doing the equivalent of 'going for last place' with this particular submission: "Why are you looking at me like I have two heads?" said Officer Cerberus Jones to the criminal he was arresting."

(I want to get 'dishonorable mention' in the fantasy category.)

Epidemic Model of Zombie Outbreak

This is too good to make up.

Some mathematicians have recently published (though apparently in a non-prominent venue or at least one that is unfamiliar to me) the following epidemic model of a zombie outbreak. It uses the standard ODE compartment models used for studying disease dynamics, although they change some terminology to suit their "application". For example, the SIR model is now known as the SZR model. (The symbol "I" stands for "infected", whereas "Z" stands for zombie.)

Basically, I don't know whether to laugh or cry---well, to be honest, I'm doing a little bit of both right now. Talk about "awesome" research. Wow.

To be fair, if you take a look at the text, this paper appears to have arisen from a class project, and I bet the students involved had a lot of fun with the project and learned a lot. I think there do exist appropriate venues for publishing such papers, assuming that the paper is written in an expository manner so that, e.g., other students can benefit from it. This paper seems to have been published in a compendium about research on modelling of infectious diseases, which is not the venue where such an audience would typically look. (It would be more appropriate to write about this kind of playful "application" in a venue such as American Mathematical Monthly that university students actually read. Then I think there can be considerable benefit to such a paper, as it can suck in some of the younger crowd.)

Fungal Necromancy

OK, this is just weird. Apparently, there's a type of fungus that infects ants so that they act like 'zombies' and die in convenient spots. Didn't I read about such strategies in the D & D Monster Manual? Bizarre.

(Tip of the cap to Kevin Macon, who will reasonably shortly be my coauthor on a network science paper. I am going to have so much fun when I give certain seminars...)

Adrian Beltre possibly lost for season with injured testicle

As pointed out, it's way too easy to come up with some sort of lame joke about this story, so instead I will only provide the straight line: Mariners third baseman Adrian Beltre might be lost for the season with an injured testicle. Ouch!

OK, fine. I need to do one joke in honor of the late great Jim Healy. Take it away Jim Harrick.

Gentlemen, I think we have a loose cannon.

I'm trying to minimize how much I discuss PEDs in this spot (because, frankly, I am sick of it and I would not be surprised to find out about possible use by anybody in professional baseball---there are just more interesting things to discuss), but on occasion I make an exception. It seems like Reds pitcher Bronson Arroyo is showing a mixture of refreshing honesty and some opinions that I find a bit perturbing. I respect the fact that he's speaking his mind---though I think he's going to ultimately get himself derailed if he keeps at it (he's being 'honest to a fault', which also happens to be one of my specialties)---but I really don't like the attitude he's showing. It seems to me that part of what he's saying is that he believes that using the stuff is ok as long as one doesn't get caught. OK, so he's far from the only person who believes that and is distinguishing himself mostly by openly admitting it (and also showing a rather familiar cynicism about what other people think), but to me it's patently obvious that issues about getting caught are not the only problem here.

Anyway, we'll see how this plays out.

Quote of the Day: Tweeting During Life's Rituals

Today's quote comes from this CNN article about using twitter during childbirth.

The quote comes from psychologist Renana Brooks: "That's like Twittering on your wedding night. You can blog about it afterward."

I don't think she intended her comment to be funny, but I find it highly amusing.

50 Years of Anderson Localization!

Do you know why I'm excited today? (Actually, this is very recent news, as I only found out about this a few minutes ago.)

Here's why: The August 2009 issue of Physics Today includes a 50 year retrospective on Anderson localization. I won't read it until my hard copy arrives, but I am very much looking forward to reading these articles.

As described in the wikipedia entry, Anderson localization is "the absence of diffusion of waves in a random medium". (Imagine a crystal with defects that do their damnedest to curtail wave transmission. Admittedly, I'm not trying to score major points for accuracy with this description.)

Tales from the arXiv: "But all the people with motivation are already on the Lloyd Special Forces team"

I couldn't help thinking of Jeremy Gawle's [sp?] line from one of the old Lloyd movies when I saw the title of this new paper on the arXiv. Here are the title, authors, and abstract:

Title: Mathematical formalism of physics of systems with motivation

Authors: Ihor Lubashevsky, Natalia Plawinska

Abstract: The paper discusses fundamental problems in mathematical description of social systems based on physical concepts, with so-called statistical social systems being the main subject of consideration. Basic properties of human beings and human societies that distinguish social and natural systems from each other are listed to make it clear that individual mathematical formalism and physical notions should be developed to describe such objects rather then can be directly inherited from classical mechanics and statistical physics. As a particular example systems with motivation are considered. Their characteristic features are analyzed individually and the appropriate mathematical description is proposed. Finally the paper concludes that the basic elements necessary for describing statistical social systems or, more rigorously, systems with motivation are available or partly developed in modern physics and applied mathematics.

My Life According to Depeche Mode (I was tempted to choose "Modern English" in deference to a certain incident on KROQ)

I noticed an interest meme on Facebook today in a post by Vincent Kong, and I decided it would be an interesting exercise to try it out (and my food was actually still somewhat warm by the time I finished). I think a few of my answers are pretty clever, so I decided to include my post in this spot as well.

Instructions: Using only song names from ONE ARTIST, cleverly answer these questions. Pass it on to at least 15 people and include me. You can't use the band I used. Try not to repeat a song title. It's a lot harder than you think! Re-post as "my life according to (band name)".

MAP's additional note: I am spending way too much time trying to be clever with this. It helps that Depeche Mode (which is my favorite artist) has such a huge catalog. This would have been significantly harder had I picked Modern English or---dare I say it?---Baltimora.

Orioles outfielder Nolan Reimold was talking about how his life has turned around since his child was born. In his words, "My life has done a complete 360 since he was born." Um...

Taking Over the Blogosphere (well, not really, but it's a dream)

The baseball networks story has been picked up by the Freakonomics Blog.


It's also been picked up by a few baseball/sabermetrics blogs, including a couple of them that are hosted by prominent people in the business. Ones that have followed up on the Wired story include 27pitches.com, The
Book--Playing The Percentages In Baseball
, Baseball Musings, and Baseball Think Factory.

I wonder if my dreams of being made fun of on SportsCenter (or at least by Bill James) will come true? ;)


The story has also been picked up by USA Today online and reached #4 on digg.com in the category of sports for a 24-hour period. As usual, the comments in the various venues have included a mixture of intelligent ones and not-so-intelligent ones. (The ones on the sabermetrics blogs have been almost uniformly great. Some of those folks have looked at our actual paper and not just the Wired article and have given some very nice academic-style food for thought regarding some things we might want to consider rephrasing in the paper when it is back on our desks. That is much appreciated!) I especially "love" the ones that expressed extreme moral indignation about some combination of (1) not incorporating PED information into our rankings, (2) not using data to which we just don't have access, or (3) not coming up with results that match their preconceptions. (Um, science isn't automatically wrong if it doesn't give the answer for which you were hoping and/or expecting!)

Oh, and I haven't gotten as much work done during the last couple of days as I was hoping... I really need to work on my scholarpedia article about solitons.

The Joy of Opening a Pack of Baseball Cards

Josh Wilker describes the joyful process of opening a pack of baseball cards. The way he describes it isn't exactly the way I would do things, but he's exactly right that there is a certain mystical feeling in opening a new pack of baseball cards and seeing what players are inside. (Hope springs eternal.) I still have some unopened packs of baseball cards at home (including some that are old enough to have sticks of gum in them) and if I were home, I could always go to the Beverly Hills Baseball Card Shop and buy some. And Wilker's article really makes me want to go and open up some packs of baseball cards. When I am back home in the winter, I am so going to partake.

Quote of the Day

Today's quote is "Finally, Oxford scientists are pulling their weight.", which opens up an article in 27pitches.com that covers the Wired article about my research on baseball networks. That's just wonderful.

Other baseball blogs are also picking up the Wired article.

Speaking of Nolan Ryan...

Yesterday was the 16th anniversary of the most lopsided fight in Major League Baseball history. No, I am not talking about Carlos Perez versus the water cooler but rather about what happened when Robin Ventura charged the mound against Nolan Ryan. (It didn't exactly work out well for Ventura.)

Six Degrees of Nolan Ryan

Last night, I had an emergency interview with Wired about a recent article my collaborators and I wrote about matchup networks of pitchers and batters. Here is the resulting article in Wired's online science section.

Somehow, I managed to resist the urge to insult Juan Pierre during the entire 1.5 hour interview, and I also got my opinion about Bert Blyleven in there. :)

Choose Your Own Apocalypse

This Slate.com article invites you to determine what you think will cause America's downfall. I'm highly amused, though unfortunately the "Power Law OF DOOM" isn't mentioned among the 144 possible causes of our downfall. (Actually, this is somewhat related to the possible cause of "complexity", but I prefer to call it the Power Law OF DOOM.) My choice of apocalypse placed me one box to the left of the average slate.com reader and almost all the one to the top of the chart (close to two full boxes above the average slate.com reader). Note, however, that I only chose the "Rod of God" option as one of my five favorite apocalypses because it was damned amusing.

Stupid Comment of the Day

The Reds' color commentator, referring to closer Francisco Cordero and the fact that he was throwing gas past the hitters, just said: "He's not in a save situation, but he's pitching like he is in one." At the time, the game was tied 4-4 in the top of the 9th. Sheesh. The game is kind of in a crucial situation (so who cares if there is a save involved)...

Washington Post Neologism Contest

Here are some winners from the Washington Post's neologism contest. This website seems to be a bit of a compilation from multiple years. Additionally, some of the lists I've seen have very slightly different definitions for some of the words. The website to which I link is a bit more extensive than some of the other lists I've seen, and that's why I have chosen to use that one. Some of them are dumb but others are quite awesome. Several of them are also "awesome". I especially like the terms for the 21st century at the bottom, which I imagine might have appeared in a source like Wired at some point. (In terms of style, they certainly remind me of the terms I've seen there...)

Experimental Results Related to DNLS Equations

The final version of this paper is actually over a year old, but it was just published as a book chapter in a monograph written by one of my collaborators (Panos Kevrekidis). Panos wrote the first sections of the book, and then he invited a number of people to contribute individual chapters on more specific topics. He asked me to write a paper based on experiments relevant to discrete nonlinear Schrodinger (DNLS) equations because of the fact that I work closely with experimentalists on a number of topics. Hence, this paper is a review article that covers a theorist's view on experimental results. (Note that I purposely ran the paper by several experimental colleagues in relevant fields to ensure that I didn't say anything stupid.)

The title of the published version of the chapter (which you probably won't be able to download for free, which is why I included the link to the version on my website) has "DNLS" because the acronym has already been well-established by that point in the context of the book.

Keep your eyes on this spot for a number of additional papers. I have a bunch of stuff that's about to come out. Also, I have a comment to make related to the first-mover scientific advantage, but I'll leave that for a different blog entry because it relates to my networks research rather than nonlinear waves research.

Electromagnetic integral equations requiring small numbers of Krylov-subspace iterations

Dodgers acquire reliever George Sherrill

The Dodgers have acquired reliever George Sherrill from the Orioles for two minor league prospects. Sherrill is a useful piece for our bullpen and should be pretty helpful. I'd rather have Roy Halladay, though. :)

We'll see later if I complain about having traded away these prospects. It all depends on how well they pan out. ;)

"I want to boot some head, too."

I just watched a few videos on YouTube related to the two skits by The Frantics in which heads get booted.

First, here is a pretty amusing World of Warcraft version of "Tai Quan Leap". (When I write "version", I am referring to the graphics that go with the soundtrack.)

Second, here is an awesome Phoenix Wright version of "Last Will and Temperament".

Finally, here is a live version of "Last Will and Temperament" which isn't very good. The YouTube label claims it's actually being done by The Frantics, but I have trouble believing it.

Also, I started watching a Super Smash Brothers Brawl version on which I gave up pretty quickly. It didn't look like it was going to be worth watching.

Mark Buehrle pitches perfect game!

Chicago White Sox pitcher Mark Buehrle pitched the 17th regular season perfect game in Major League history. (There has also been one postseason perfect game.) This is his second no-hitter. Buehrle also pitched to the minimum 27 batters that time (one person got picked off). Nice!

RIP Gidget the Taco Bell dog (1994-2009)

Weirdest baseball exhibition game ever?

Back in the day (in 1926), there was an exhibition game between a KKK baseball team and a Jewish team. Apparently, it also turned pretty ugly after the game. I suppose the game was intended to help mend things, but it clearly didn't work.

Nature versus Science

It's not quite the epic battle of ninjas versus pirates or even pirates versus ninjas, but there is at least some pizzazz to the battle of Science versus Nature. Here is a recent depicted of this battle in PHD Comics. (Check out a particular square on the Monopoly board. Ouch!)

Best. Press Release. Ever.

I thought this was a joke when I first read it, but apparently this is a real press release.

The money quote comes at the end of the press release (bold words were bold in the release):

“We completely understand the public’s concern about futuristic robots feeding on the human population, but that is not our mission,” stated Harry Schoell, Cyclone’s CEO. “We are focused on demonstrating that our engines can create usable, green power from plentiful, renewable plant matter. The commercial applications alone for this earth-friendly energy solution are enormous.”


Wow. I'm at a loss for words---well, except for the fact that one of the sites that promulgated the flesh-eating robot news was apparently FoxNews.com. I hate to break it to you, guys and gals, but she already works for you.

Name of my New Computer

Unless somebody changes my mind quickly, I have just decided to name my new computer "Trefoil" (well, technically for the current hard drive). The use in both mathematics and for the biohazard symbol is just too good to resist. I was thinking of using a "sweeter" name (like the name "Duende" I used for one of my old hard drives), but this was the first name that came to mind that I really like.

Now I just have to finish setting up the new computer. I am copying older stuff in a piecemeal fashion that was necessitated by the issues with the old computer. Sadly, this takes a lot longer than a simple user transfer. I also need to register the Mac address with Somerville's IT people to get online directly without at least some monkeying (or going to a different location), so I won't be finished with the setup until at least tomorrow. I'm sure it will take me a while after that to reinstall software, so I'll probably stick with immediate needs. I already have stuff to do that needs LaTeX, and I expect to need things like Matlab, MS Office, etc. soon. I also have the urge to start a new game of Civ IV, but given all of the urgent work I have right now, that really ought to wait for a long while. (Let's see how well I do with that.) I also plan on downloading a bunch of music via the iTunes store. I have taken advantage of not having my playlist on the old computer by listening to a flashback alternative station that I really like (that I hadn't listened to in a while but which I enjoyed during iPod gaps in the past). Every time I listen to this station, I hear songs I forgot about or that I otherwise really like (and that I hence want to acquire), so one thing I really need to remember to do this time is to occasionally listen to that station rather than my own playlist. Some of the songs will likely be very hard to acquire, as this station plays lots of deep cuts, many of which I suspect are from sources that unavailable via iTunes and often just no longer available without scouring for used material. Once I get my new computer online, this is on the docket. Then I can enjoy some of these songs while I get some of my urgent work done.

I'm now online with the new machine using internet sharing (Thanks, Lemming!), though admittedly faking my old computer's Mac address would have been a cooler way to solve the problem. :)

Pictures from Sevilla trip

Here are a bunch of pictures from my Sevilla trip.

More from Sevilla

I am sitting in the air-conditioned hotel lobby. I will shortly be calling a cab to go to the airport. Here are some more things to report from the last couple of days:

1. Today I walked through a rather large local park for a while. (I assume this is listed among the tourist attractions.) I encountered two museums on the other side, so I looked around in those for a while. One of them concerned archeology and the other concerned art and lifestyle. I took an awesome picture of a cat chilling in the shade outside the later (Saturday catblogging!), and that will almost certainly make my photoblog today. I have some great picture of buildings and scenery as well, but this particular picture is so damned cool that I don't care that it isn't particularly Sevillian. On the way back, I naturally got lost and even started walking in the exact wrong direction at some point---I was even on the exact right street, but my direction sense is so bad that I was 180 degrees off with my subsequent choice of direction---but I eventually figured it out, walked back, accidently found a cafe in the process, had coffee and read for a bit, and then made it back to the hotel. (The cafe had lots of chocolate drinks too, but it's bloody hot here so I wasn't in the mood for a hot chocolate, and I figured trying to ice the drink would screw up the consistency.)

2. Several people asked me for directions (in Spanish, of course). They didn't realize how doomed they were. Naturally, I responded that I didn't know and was not from here.

3. Outside the conference room there is a fire extinguisher with the label "UNIX". ("This is a UNIX system. I know how to use this.") I will post this in a directory with other Seville pictures so that you can see some things aside from what I put in the photoblog. Stay tuned...

4. On a few occasions, I did some translating for other conference attendees when they were asked questions in Spanish that baffled them.

5. Several of the streets had a walk signal that consisted of a green animation of a person walking. In such cases, the animation would start to walk much faster just before changing to red. (There was no yellow signal.)

6. Wednesday night's social event was a boat trip on a local river. I have already posted one picture from that, and I will post a few more.

7. Thursday night's second social event was the banquet. Almost none of us got enough sleep that night, which made giving my talk on Friday morning a bit harder than it otherwise would have been. It also lowered attendance somewhat.

8. Just before the banquet, we had a tour of the Alcázar of Sevilla. There were a lot of us, so we split into two---not each person; half of us went with one tour guide and half went with the other. We had a choice of a tour in Spanish or one in English, and naturally I chose the former. I would have never lived it down if I hadn't and I wanted to test myself anyway. I had to concentrate much more than I would have with the other choice, but I understood almost every word that was spoken. The hardest parts were when it was a label that I couldn't apply without context (such as in a couple of cases indicating what material something was made of) or when it was a word that was different in Spanish Spanish than in South American Spanish. (The Spanish I know is partly generic Spanish and partly South American Spanish.)

9. The conference ended yesterday with a psychoceramics talk in which the speaker attempted to develop his own version of electromagnetism. I looked at his website, and he's actually written a lot of serious papers in top physics and applied math journals, so I guess he just jumped the shark at some point (or, if you prefer, contracted Josephson Disease). I hope this never happens to me.

10. Dinners in Spain are bloody late. Granted, this has a lot to do with having siestas when the sun is at its peak and being out late at night instead. Our conference dinner on Thursday started at 9:40 and I got back to the hotel at 12:30, and I was one of the first ones to leave.

11. I left for Thursday's events at 7:30 pm. When I came back at 12:30 am, there were 30 work e-mails waiting for me. Sheesh. Some of my collaborators work very hard. Naturally, I went through these before crashing, though my page proofs will have to wait until my return to Oxford. (Actually, because I am setting up my new computer tomorrow, I will probably start on them on Monday.)

12. After the conference ended on Friday evening, we probably had over ten people from the conference in the hotel lobby doing work or other stuff of various forms on their computers at around 8:30 pm. What a bunch of nerds! :)

13. I think I might have been the only American at this conference. There were people from US universities.

14. I seem to have procured a visit to Singapore on someone else's dime. This goes along with the trip on someone else's dime to Belgium that I procured at the last conference and the invitation to Germany I already had. (Actually, I also have been invited to stay with a friend when I visit Berlin, though she's usually located in Oxford, so that one will require some coordination.) Anyway, it looks like I have some good opportunities in the near future to add to the countries I've visited. I will be in Poland next month, and of the others I expect to knock off Belgium first.

15. One of the conference attendees was someone I had met in grad school (and whose wife was a fellow CAMster). I had heard of him but didn't remember him at first. As is usually the case, he knew exactly who I was immediately. Another attendee had been a grad student at Georgia Tech when I was a postdoc there. Conferences are always good for encountering people one hasn't seen in a while.

16. There were more demands from my professional colleagues for pictures of me in my Oxford cap and gown. I am going to be an Examiner this Friday, so that's the next time I am wearing that stuff. One of my friends has offered to help with the picture, though I need to check whether the timing this Friday will be workable. I'll let you know if such a picture becomes available that quickly.

17. And on the third day of the conference, we were interrupted by ninjas. Sadly, they were way too fast, so I couldn't get a picture of them. I wish I had had my camera out. They took advantage of the fact that we were having our coffee break so that the girl who was filming them could catch them running out from behind the posters. Interestingly, most of my colleagues didn't seem to notice. I should have gotten my camera out as soon as I saw the girl preparing her camcorder---I hadn't notice the "ninjas" going to hide amongst us. Ah well, they were ninjas, so I guess that gives me a decent excuse for not being fast enough to take a picture of them.

Photoblog!

As promised, I am starting a new photoblog now that I have a digital camera. (Props to Arcane Gazebo, from whom I shamelessly stole this idea. I believe he might have done the same thing, but anyway I got it from him. Perhaps he got it from Agnes?)

I am hosting these pictures on Facebook, but I have arranged the settings so that one does not need an account to view the pictures. (Let me know if this doesn't work.) The link for the first album in the photoblog is here.

Each Facebook album supposedly can hold 200 pictures, so I'll give you a new link once I get to picture 201. My plan is to post my "best" picture from each day. The basic requirement is that I have to take the picture, though I anticipate that there might be exceptional circumstances from time to tim in which there is a subsequent photographer. I will post one picture for each day. Thus far, I have only posted my 7/15/09 photo.

A list of things for physicists to know

Here is an interesting essay about all the things physicists really need to know. It appeared in Physics Today in 1993 and can easily be adapted for any subject, because none of it really has anything to do with physics. I follow some of these, but I certainly don't do certain ones. :)

(Tip of the cap to John Preskill.)

Quote of the Day

Main conference organizer (upon meeting me for the first time): "I thought you were older."

Me, in response: "I hope I will be some day."

His reaction: He didn't know how to react and the conversation abruptly ended right there


(Note that I am going to choose to view his comment as a compliment---in reference perhaps to how well known I am for my work. I don't actually know if that's why he thought I was older.)


In other news, our conference package included a cap (advertising the university) and a bottle of olive oil. WTF?

Seville so far

The conference doesn't start until tomorrow, but there are already several good signs that this one will work out better than the one in Venice:

1. My hotel is much nicer. We've got wireless in the lobby (as opposed to no internet at all, which meant I only had access during the day) and we actually have a tub instead of just a shower.

2. Several of my collaborators and others I know are all staying in my hotel. Granted, I do know more people at this conference than at the last one in general, but this is still a very good sign. It will also ease discussions and food acquisition.

3. It helps a lot that I more or less know Spanish. (I'm not as good as I ought to be.) I actually got completely through the airports in Spain without speaking a word of English. I understood the people perfectly and while I made some mistakes, I didn't have much trouble. I was able to get a proper iced latte by explaining what it is I wanted, and I never succeeded in getting a proper ice espresso drink in either of my two trips to Italy. Also, I had a nice steak sandwich at the Madrid airport. The default option was plain (as in meat and bun only)---I approve!

4. In Sevilla, I found a gelato place where I ordered a really good (apple) thick, practically-invertible milkshake. I was worried about the thickness, but I was pleasantly surprised by this. Yes!

5. I very much like having the opportunity on this trip to practice my Spanish.

6. I am really enjoying having a digital camera, and I expect this to continue.

7. There is some weird word usage and pronunciation here. For example, people just drop the final consonant in a word, so (for example) "gracias" sounds like "gracia". I had heard about this but didn't realize that it was so pronounced. Also, I see a lot of "os" in places where it should be "as". For example, the word for shoes is "zapatas", but I saw a lot of store signs for "zapatos". I still haven't figured this one out.

8. I knew what one particular menu item was specifically because of the nickname of a baseball player---"pulpo" (octopus) for Antonio Alfonseca, who has 6 fingers/toes on each appendage instead of 5.

9. I need to remind myself what the words for things like "menu" and "reservation" are, but I am remembering some long-forgotten vocabulary very quickly. Getting some of my Spanish ability back (and also testing it for the first time in a real situation rather than just practicing) was something I was really looking forward to on this trip. (OK, upon looking this up, it turns out that I do remember one way to say "menu" correctly and---despite how the guy at the hotel reacted---it turns out that I did use a correct version of "reservation". The thing is that I specifically used one that was American---as in South American---which is perfectly forgivable given that my father is from Argentina! (I said in Spanish that I had a reservation and the guy immediately switched to English because he apparently decided that I couldn't speak Spanish. Bah!)


Stay tuned for more updates...

Digital Camera Tips?

Now that I (finally) have a digital camera---which arrived while I was in Venice---I am planning to steal AG's idea (that I suppose he stole from others) and try to keep up a photojournal with one picture a day for a year or more. (Ideally, I'll keep it up for longer, but one consecutive year is a good goal.) I am not planning to wait until January 1st to start, but I do need to practice more with my camera before I start. (That said, if any of the pictures I take in Sevilla are fantastic, I might well start right away.) In my practicing, many of my pictures have been blurry, and I am trying to adapt to holding this camera differently than I did with previously-conventional ones. Any pieces of advice for helping me with this transition?

The Porter of Seville

AKA: Lo que pasa en Sevilla se queda en Sevilla. (I'm pretty sure that one should use quedarse here rather than quedar. An online Spanish-English dictionary seems to back me up. Let me know if I got this horribly wrong.)

AKA: What happens in Seville stays in Seville.

Also, while my upcoming status as the Porter of Seville isn't as cool as The Rabbit of Seville or even The Barber of Seville, I think it's pretty damned good. Naturally, I earmarked that title for this particular blog entry when I first decided to attend this conference. (I don't normally come up with entry titles several months in advance, but this one was just too good to pass up.)

Early tomorrow morning, I will get on the bus to head to Heathrow airport for a morning flight to Madrid. I will then stay in the Madrid airport for a several-hour layover before I take a "one hour" flight to Seville. (I seriously should have found a better configuration.) I suspect that only about 30 minutes of that flight will have actual flying. I will be attending LENCOS, a conference on "Localized Excitations in Nonlinear Complex Systems". In practice, this will entail lots and lots of talks on solitary waves and allied concepts. This is rather narrow in scope mathematically, though a wide range of applications will hopefully (and likely) be represented. One thing I really like about the conference is that there are no parallel sessions and that it is a level playing field---every talk is 20 minutes + 5 minutes for questions. My past experience with relatively small conferences in which everybody sees every talk have been quite good. This format is usually quite conducive to meeting and have lots of chances to talk to other people, which can be particularly beneficial for young scientists who might otherwise be virtually ignored by their senior colleagues. There are supposed to be some posters as well (for people who chose to do things that way), but I can't see any reference to them on the website.

Interestingly, the conference venue was supposedly the inspiration for Carmen back in the day. I need to find a way to get "The Toreador Song" (or maybe "The March of the Toreadors", which would probably work better) into my talk. I will be presenting a talk on granular crystals.

Venice Roundup

Here is a belated roundup of some of my misadventures in Venice. I had been looking forward to the conference, but sadly it didn't work out very well. Here are some highlights and 'highlights':

1. One thing that partly amused me and partly made me uncomfortable because of my proximity were the geriatric boat lesbians on my boat ride to the area of Venice where my hotel was. It was of course nice that they were crazy about each other, but in general I prefer not to be so near anybody who can't take their hands off each other, especially when I get slightly bumped in the process. I guess Venice really can be quite romantic for some people, though the city didn't strike me as overly romantic when taken as a whole.

2. On the first night of the conference, I was going to join a bunch of fellow NetSci attendees at a private tour of a the San Marco Cathedral that the conference organizers had arranged. Sadly, I missed several obvious signs when walking there and ended up at the other side of the city instead. Who knew that the city had more than one giant domed building? So I paid 10 pounds for the privilege of getting hopelessly lost and stressed out in a hot, humid place. Thankfully, knowing Spanish eases communication with the locals quite substantially, and I took advantage of that when I finally realized how hopelessly lost I was and tried to get directions to get back to the hotel. (Venice is a really easy city in which to get lost, which bodes poorly for people like me who have a horrible sense of direction. As it turns out, one of my problems was that the direction that I thought was east turned out to be south.) I ended up having gelato for dinner and being depressed for a while, although the three hours of novel reading I did that night eventually got me out of it. My inability to find the cathedral also provides an excellent illustration of the difference between the concepts 'All Roads lead to San Marco' (which is what fellow conference attendees insisted when I explained to them that I got lost) and 'a set of measure 1 of roads, in the limit as the number of roads tends to infinity' leads to San Marco---namely, I managed to find some roads that would have measure 0 in such a limit. :( Also, Venice has the shortest mean free walking path of any city I have ever been in.

3. Our conference dinner was on the third night of the conference. I was not very impressed. Also, I ended up sitting on my own for quite a while and talked to almost nobody for 3.5 hours during the event, so my mad social skillz really helped me out as well.

4. The lead organizer of the conference technically still owes me gelato. I needed to pay an extra fee to my bank in order to be able to wire money to register for the conference. (Such a transfer was the only payment mechanism.) He promised to buy me gelato and even brought it up again during the event, but I guess this will have to happen at a future conference.

5. We had our group dinner the night after the conference dinner. Four out of the six Oxford people attended. We had a much lower showing at this conference than we did in Norwich for NetSci 2008.

6. I walked around Venice with one of the Oxford grad students on Saturday before I headed off. There were a couple of neat stores, such as one with some fancy chess sets. We also saw some of the art exhibitions.

7. I seriously considered buying a funky jester hat---if for no other reason than to wear it at High Table at some point---but I didn't end up getting one. I'll try to pick one up the next time I'm in Venice.

8. I dropped my laptop onto a quite solid, 200-year-old marble surface. This provides an excellent example of an exogenous shock, as my computer was functioning quite effectively before I did this but not afterwards. My new laptop is on its way... (Also, this was the straw that broke the camel's back. I already wasn't very happy because of a couple of the items above, but then after this I basically really just wanted to go home.)

9. I gave my talk in a church. It was really pretty inside, but I felt the need to be somewhat blasphemous.

Obscure Baseball Rules Quiz

Here is a quiz on obscure baseball rules. (Note that this is a quiz about obscure rules rather than an obscure quiz about rules.) It is apparently part of an advertisement for some book about how to become an umpire. I found the advertising statements in their descriptions of the correct answers to be rather annoying, but the quiz itself is cool, so I'm passing it along anyway. I only got 4 right out of ten, though a couple of the ones I missed are rather cheap and depend on the interpretation favored by the book being advertised.

(Tip of the hat to Rob Neyer.)

A promising career move?

You know, I could increase my salary by becoming a witch.

Optical Illusion of the Day

You might remember that I posted a link a while back to this awesome optical illusion of a spinning silhouette. (I can't find my blog entry on it at the moment, so I must not have tagged it very well.) Here is a more generic but still cool optical illusion that I mentioned previously.


Well, here is another really awesome optical illusion, which was posted on Bad Astronomy. Damn! It's probably not as cool as the silhouette, but I still really like it. It also makes me thing of the green/blue paradox (or whatever that's officially called). :)

Also, here is an aural illusion that I can't get to work. I get exactly the same thing whether or not my eyes are open or closed. Can somebody explain this one to me?

Mathematics Employment Task Force

The the results of the Mathematics Employment Task Force have now been published. The 68 departments surveyed had 40% fewer doctorate-required positions to offer. This aligns rather closely with my expectations based on anecdotal discussions, but ouch is still an appropriate word to use.

2009 Baseball All-Star Teams

The 2009 baseball all-star teams have been announced. Well, that isn't entirely true because there will be 5 National League Players and 5 American League players for whom the fans can vote. There will also invariably be injured players (and perhaps even "injured" ones) who will be replaced by other people.

At any rate, here are the current National League and American League all-star rosters.

The possible additions for the AL are Chone Figgins, Brandon Inge, Ian Kinsler, Adam Lind, and Carlos Pena. My choice here is Adam Lind. My second choice would be Ian Kinsler.

The possible additions for the NL are Christian Guzman, Matt Kemp, Mark Reynolds, Pablo Sandoval, and Shane Victorino. The way I see it, there is one excellent choice (Sandoval), two choices that are not as good but not horrible (Kemp and Reynolds, with the latter more deserving), one choice that is somewhat worse than that but still not horrible (Guzman), and one choice that seems to be rather nepotistic (Victorino, who is a fine player but is not having anywhere near the 2009 as the others).

Equation of the Day: Laptop + Marble Surface = Bad

So, it turns out that computer hard drives tend to have some serious issues after a computer is dropped onto a 200-year-old marble surface. (This week's life lesson: laptops + marble surfaces = bad.) Does anybody have any name suggestions for the name of my new computer? (As you might recall, my current one is called "Hourglass", in honor of a certain character and very much with a pun intended on its lifespan.) Applecare is still going for the current computer, so I am going to try to get that repaired as soon as the new computer arrives. I'll thus need a new hard drive name for the present machine as well. I should also mention that my last hard drive failure occurred right after my only other trip to Italy, so I might need to stay away from that country.

By the way, here are the specs for my new computer (I hope it's readable even with the copy and paste):

MacBook 15 inch 1 Z0GH

MacBook Pro 15-inch Glossy Widescreen 1 065-8668
Display

Keyboard (US) & User's Guide (English) 1 LL065-8482
Country kit 1 065-8484

500GB Serial ATA Drive @ 5400 rpm 1 065-8667

Mini DisplayPort to VGA Adapter 1 065-8472

SuperDrive 8X (DVD+R DL/DVD+RW/CD-RW) 1 065-8466

Mini DisplayPort to DVI Adapter 1 065-8468

Apple Remote 1 065-8476

8GB 1066MHz DDR3 SDRAM - 2x4GB 1 065-8458

3.06GHz Intel Core 2 Duo 1 065-8455

EMEA CC-HE contract uplift MacBook 1 S2366 (aka, Applecare)

HP Photosmart C4580 all-in-one 1 TS420 (my first ever printer!)



This computer is the most expensive Mac laptop ever purchased from Oxford's Mathematical Institute. (I am paying for it with money from my McDonnell grant that was set aside for a high-end laptop.) It is almost the most expensive laptop purchased through the MI, but one from back in the day when laptops were much more expensive slightly trumps it. It is nowhere close to the most expensive computer purchased through the MI, so I'll be sure to let you know if I ever approach that.

Oh, and why I am so giddy right now even though I was just in a shitty mood from this conference and am now spending lots of time getting my data back-up situation in order (there was a bit of comedy of errors involved there as well): Simple. It's because I'm getting a fucking powerful computer that will probably give me my biggest performance jump ever when compared to my previous computer.

What happens in Venice stays in Venice

Tomorrow morning I hop on the bus (in my best Paul Simon impersonation, though I am guessing most of you won't get this allusion) to head to Gatwick airport for a flight to Venice. This will be my second trip to Italy---I went to Rome last July---and my first trip to Venice. I am going to attend NetSci 2009, a physics-oriented network science conference. I will attempt to get a picture with Lazlo Barabasi and Gene Stanley of me wearing my new power-law t-shirt ("I went to a physics conferences and all I got was a lousy power law."), and I also expect good pasta and gelato to ensue.

My new digital camera hasn't arrived yet, so I would lose the last approximately 15 exposures in my last roll of film of the analog camera that I bought during my first year of grad school (so about 10 years ago). One of my friends very kindly offered to loan me her digital camera, but I would feel very guilty if something happened to it, so I declined the offer. (I did waffle a bit, and it's only because this is a very close friend that I even considered accepting the offer.) A few weeks ago, when I mentioned to Somerville's domestic bursar in a conversation that I was going to a conference in Venice, she mentioned that I should find a girl while I'm there. Most likely, this isn't going to happen, but I have an incredible urge to take a picture of jailbait to bring back to the domestic bursar. (Hell, I probably would have borrowed my friend's digital camera if I felt that I were actually going to go through with taking such a picture. Given that I have 2 year's worth of film to get around to developing at some point, things just won't have the same effect if I take the picture with my present camera.) My new camera should arrive right after I return to Oxford, so maybe I'll do this in Sevilla (where I'll be going on July 13th).

Anyway, stay tuned...

Internet Traffic and Michael Jackson

When I wrote my blog entry yesterday, I found myself unable to access Michael Jackson's wikipedia entry. Here is an interesting CNN.com article on internet traffic that resulted from first rumors and then reports of Jackson's death. Part of me is still weirded out by the whole thing---it's hard to think of him as gone---though the more analytical part of me is seeing yesterday and today as something that reflects the modern era more than most days.

As interesting as the article is, it's also somewhat self-serving with respect to what it says about modern versus traditional news sources: "The need of the professional media to be first with the news -- many did for a short time report the Goldblum rumor as fact -- adds further veracity. And, of course, the whole process is speeded up by the Web." Yeah, and all bloggers live with their mothers and write their material from their room in the basement.

Update: Mariano Beguerisse Díaz sent me the following article about google searches related to Jackson's death. As he reminds me, from a technical standpoint, such dynamics result from what is known as an "exogenous shock" (as opposed to endogenous dynamics that would refer, e.g., to normal search traffic patterns).

RIP Michael Jackson (1958-2009)

Pop icon Michael Jackson has died after suffering cardiac arrest. Among other things, he was an instrumental part of 80s music.

Earlier in the day, Farrah Fawcett died. (She was one of the original 'angels' in Charlie's Angels.)

(Tip of the cap to multiple Facebook users. More and more, I find out certain things for the first time via such posts, which seems to be an increasing trend more generally---going along with tweets, of course.)

Update: I have heard several others (from my generation and also from people about 10-15 years older) say that this feels like a piece of their childhood is gone. I don't feel that way, but this one definitely feels much weirder than most even though Jackson for a long time has seemed like he was on a trajectory to die young.

Tales from the arXiv: Super Mario and the Zeno Effect

arXiv:0906.3958 (*cross-listing*)
Date: Mon, 22 Jun 2009 08:59:18 GMT (221kb)

Title: Super Mario's escape trip -- a proposal of
object-intelligent-feedback-based classical Zeno and anti-Zeno effects
Authors: Shi-Jian Gu
Categories: physics.data-an physics.class-ph quant-ph
Comments: 4 pages, 4 figures
\\
Super Mario is imprisoned by a demon in a finite potential well. She can
escape from the well with the help of a flight of floating stairs. However, the
hateful demon may occasionally check her status. At that time, she has to make
a judgement of either jumping to the inside ground immediately in order to
avoid the discovery of her escape, or speeding up her escape process.
Therefore, if the demon checks her too frequently such that there is no
probability for her to reach the top of the barrier, she will be always inside
the well, then a classical Zeno effect occurs. On the other hand, if the time
interval between two subsequent checks is large enough such that she has a
higher probability of being beyond the demon's controllable range already, then
the demon's check actually speeds up her escape and a classical anti-Zeno
effect takes place.
\\ ( http://arxiv.org/abs/0906.3958 , 221kb)


Comment: Mario is not female. If the author wanted to be sexually ambiguous about a Mario character, then he/she should have used Toad instead. I will admit, though, that the paper's title and abstract compelled me to look at a paper I would have otherwise ignored. Also, figure 1 and reference 5 amuse me. :)

Update (6/29/09): A revised version of this paper has now appeared on the arXiv. I didn't look at the new paper, but the one correction I noticed in the abstract was the use of "he" to describe Super Mario. :)

The Sounds of Silence

Wow, it's been 5 days since I posted anything. That's an eternity of silence for me.

I don't have much to say at the moment, and the entries I plan to write are rather long ones (and I am way too tired to do that right now), so here's a summary of what I've done since I wrote the last entry on Friday night. I have been sleeping rather poorly for the last couple of weeks, so I've definitely been quite tired lately. The one nice thing about insomnia, however, is that I've put a lot of time in revising several papers. I have also spent some time reading a novel and have finally ordered a digital camera, though it looks like that won't arrive until after I return from Venice on the 4th of July. Anyway, here is what I have been doing:

Friday night: I saw Transformers 2.

Saturday: I finished small revisions on a just-accepted paper (my survey/review article on community detection). These were practically all adjustments that I decided for myself that I wanted to make, as the journal accepted the article 'as is' aside from minor changes in format to be consistent with the journal's requirements. I then worked on revising a draft of a different paper and then went to a friend's house for dinner. (I was my usual stubborn self about eating what she cooked, but the company was excellent. I knew all of the guests, which helps my social comfort level.) I read a bit as well, of course.

Sunday: I finished my pass through that paper and then did some other work and novel reading.

Monday: I worked a bit on my scholarpedia article on solitons, which ought to have been finished a while back. I also read a little of the dissertation I was supposed to read (and the novel, of course) and then started revising a draft of another paper that landed on my desk during the evening. I finally also started Okami---I had previously only gone through the introductory sequence.

Tuesday: I finished going through the previous paper and I made some revisions to yet another paper (though I didn't make a full pass through it but rather just attacked specific parts). I then played some Munchkin Quest and had a bit of trouble with an ancient, lightning-fast potted plant. I was at level 10 when the game ended, but I didn't quite win.

Today: Part 1 of Examiner MEGA-meeting. When we were not making decisions about the final grades of some of Oxford's finest students, we also went to lunch and dinner.

Tomorrow: Part 2 of Examiner MEGA-meeting. Then maybe I'll get back to working on another of the papers that I hope to submit imminently (if one is on my desk) or I'll get farther into the dissertation, which is on conformal field theory. At night is the SCR leavers party for some of my colleagues who are retiring or otherwise moving on. Last year's was quite fun---the speeches reminded me a bit of the ones at Lloyd House's beach trip.

Friday: Lots of meetings with students, which I backloaded onto Friday because I couldn't make the normal times today and tomorrow due to the MEGA-meeting. Then the plan is to have late lunch/early dinner with a friend on Friday and then perhaps to read, play Okami, or crash.

Saturday: I will need to get some stuff ready for Sunday's trip to Venice. I might also take a look at the slides for my talk and work on a paper. I'm guessing some Okami and reading will also be on the docket. Maybe I'll also go see Fermat's Room? Sleep would also be nice...

Sunday: I fly to Venice for the NetSci 09 conference. Sadly, my digital camera isn't slated to arrive until after my return.

Take that, Open Access Journal!

Sometimes one just has to prove a point, as a Cornell graduate student has recently done with one particular open-access journal by submitting a hoax paper that was written algorithmically. For some of you, this incident should ring familiar, as physicist Alan Sokal submitted a hoax article in 1996 to attempt to prove his opinion that a certain field of study was crap.

One thing that really interests me is that I found out about this via Cornell University's official Facebook posting. I think it's awesome to prove the point because sometimes that's just what needs to be done, but I'm a bit surprised that the University would be willing to publicly endorse the action. This incident might have some interesting fallout... (Hopefully, it won't include the grad student's career, because I suspect it's easier for a well-known person like Sokal to continue professional scientific endeavors after such a stunt than it might be for somebody who is trying to establish him/herself.

Quest for the Woolly Owl: 2009 Edition

On the fine day of 16 June 2009, a team of intrepid young swordsmen swordspeople mathematicians stepped on a bus at the ungodly hour of 8am (having previously woken up at even less godly hours such as 6:45) to proceed to Cambridge, which one of the signs along the way identified ominously as "NORTH". In fact, there were quite a few ominous signs on the way---most of which involved warnings of danger of some form. (Perhaps some giant elastic BLOB might appear there?)

What was the point of this quest? Well, besides avoiding tutorials (at least for one day), these fine young mathematicians and their faculty slaves mascots colleagues were on an epic quest for a mythical object known as Ock The Woolly Owl. Rumor has it that it looks kind of like this. Occasionally, it might even look like this. But I digress.

Our intrepid adventurers set foot on Cambridge soil at the slightly more godly hour of 10:15ish. Naturally, the first thing they did was mark their territory accidently block the exit to prevent some of the faculty from getting off the bus. (Truth be told, I think I contributed to the blocking.) They then received treasure in the form of slips for free coffee. And just to make sure were were aware that the coffee machines were in order, the two machines had displays that showed the words "working" while the caffeinated bliss mediocre coffee was being poured.

As I mentioned above, yesterday's battle was an epic one. It wasn't exactly on the scale of Pirates versus Ninjas or even Mario versus Donkey Kong, but it was still pretty damned epic.

The first presentation was given by Ed Brambley, who spoke about "Introduction and Timekeeping". That woke everybody up and was given a neutral score so as not to advantage the Cambridge side. That was when the fluid mechanics talks started flowing. And for most of the day, they pretty much didn't stop. Before the day started, I had heard rumors that certain Oxford faculty asked tough questions during Cambridge talks and certain Cambridge people asked tough questions during Oxford talks. This didn't really happen this year, though a few of us had our moments. (I was wearing my power law t-shirt, so I was not about to let fly a power law to which I had objections.) Some of the tough questions came from Oxford mathematical biologist Thomas Woolley (no relation to the owl), which didn't surprise me at all given I was on the receiving end of those during my perturbation methods lectures last school year.

During one of the breaks, it was uniformly decided (at least by the Oxford crowd) that the Oxford talks had sexier titles. Perhaps this will lead to a victory in a future competition on grant proposal writing? (And with EPSRC running the show, that method will probably lead to about as much success as writing a good proposal. But I digress.) During the talks, the Cambridge students kept bringing up the famous Cambridge mathematicians who had previously studied the problems they were working on. (This probably explains why they hadn't been solved yet.) The Oxford mathematicians kept bringing up Cambridge mathematicians in their talks. They also kept bringing up Ock. We can only speculate how such slides will be filled in the future when he retires.

There were various other talks, though most of them were about fluid mechanics. (A few others---especially on the Oxford side---touched on other topics.) The BLOB did finally show up in the only mathematics seminar I have ever seen that mentioned Cthulhu. I just thought I'd get that in there. In total, there were 9 talks from each side, but alas our interpid adventures came up short, as the neutral unbiased dispassionate detacthed equitable nonpartisan judges (Amit Acharya and Graeme Wake) awarded Cambridge a narrow victory over Oxford. Of course, I am giving out the names of the judges to give them credit for their hard work, though I do worry that some bitter Oxford faculty students or postdocs might google their snail mail addresses in order to send them mail bombs (or at least unsolved fluid mechanics problems). This, of course, meant that the Woolly Owl will be remaining in Cambridge for the next two years. Until then, the pressure will be building on our side (aka, "Good") to reclaim this mystical trophy in 2011 when Cambridge (aka, "Evil") descends on us in 2011.

Once the Woolly Owl was awarded, many of us headed to the Castle Pub, which is one of only two Cambridge pubs I had previously entered (that was in 05, when I didn't know that I'd ever be living in this country) At 7pm, we boarded the bus back to Oxford. Ock told me that the route would be a different one from the morning for the express purpose of making life easier for those of us with motion sickness. (I didn't bother to verify if this was the actual reason, but I was apparently looking like what I like to call "my best" when I crashed Somerville's SCR after-dinner drinks upon my arrival.) Despite constant threats on his life (mostly by Ock), Grame Wake managed to survive the bus ride intact. And so our intrepid heroes came back on their shields, but they nevertheless alighted from the bus at about 9:15 or so with sincere promises of revenge on their lips and probably headed over to another pub.

And so I write this journal entry with extreme sleep deprivation (even with one day having passed) and provide a Call to Arms for the 2011 Quest to Reclaim the Woolly Owl. In the words of the immortal Duke Nukem: "Come get some!"

"Trivial" is the new "MacBeth"

There was an amusing incident in tutorials last week that I forgot to mention in this space. It occurred on Wednesday, which was mostly sunny except for a quick torrential downpour for about 15 minutes in the morning and then an even more torrential downpour for maybe 20-30 minutes during one of the afternoon tutorials. It had started to rain pretty hard, and while I was explaining a problem, I mentioned that a certain part was "trivial". With exquisite timing, we immediately witnessed our first thunderclap of the day as soon as the word got out of my mouth. It was loud enough that it startled me, which I suppose helped make the whole incident even more memorable.

Old-School Forward

This is the text of an old forwarded message that Ben Williamson sent to me on 10/30/98. I was thinking about it today for the first time in a while, so I decided to dig it out. Even after all these years, it still brings a smile to my face. Here goes:

A Man walks into a supermarket and buys:
1 bar of soap
1 toothbrush
1 tube toothpaste
1 loaf of bread
1 pint of milk
1 single serving cereal
1 single serving frozen dinner

The girl at the checkout looks at him and says "Single are you?"

The man replies very sarcastically "How did you guess?"

She replies "because you're fucking ugly"

They ran, they ran so far away

In one of last week's baseball games, the Cleveland Indians got a 4-3 walk-off win against the Kansas City Royals with the assistance of a flock of Seagulls. Thankfully, some of the articles include the obvious joke. Where is Dave Winfield when you need him? (Actually, I would love to have watched a Baseball Tonight episode discussing this incident when Dave Winfield is one of the hosts just to hear the inevitable snarky comments. If that doesn't ring a bell, take a look at item #6 on this list.)

Shiny New Principal!

Starting on September 1, 2010, Somerville will have a shiny new Principal. (Note that the current one is quite good, but she is set to retire at that time.) The Somerville Fellows elected her (and she accepted the position) a little while ago, but the official public announcement was today. Hence, I can finally write this blog entry. The election process is best described as "interesting".

(In the press release to which I linked above, a number of Somerville researchers were (correctly) described as "world class". Here's to hoping that I'll accomplish enough to be worth mentioning in that light the next time we elect a new Principal.)

(Approximate) Quote of the Day: Overheard in the Clarendon Building

This afternoon, I was in the reception hall for the big lecture theatre in the Clarendon Building just before Michael Berry's talk. One physics professor asked another if he was done with grading exams, and here was his approximate response: "I finished a few days ago. Since then, I've been working on bloody papers and acting smug."

Comment: Here, here!

Making Friends in Oxford

I've been going through another one of my thoughtful phases recently, and I've been pondering the fact that the places in which I have been able to most easily make close friends are first Caltech and now Oxford. I have made a few pretty good friends here, and there is one local with whom I'm especially close who I would put up there with just about anybody I've ever met and as far as I'm concerned is a friend for life. It's also particularly nice for my mental state when I am slaving at work and I get an unexpected knock on my door. The gentle nudging to try to convince me to eat and sleep a little more properly are also much appreciated, and I occasionally even follow that advice. (Our first interaction was kind of interesting, so I certainly wouldn't have predicted this at the time we first met in fall 07. In retrospect, I probably should have, but it's easy to say that.) I know I've been here for about a year and a half now, but Caltech is the only other place where I've met such people on this kind of time scale. (And it's not like I haven't made close friends in other places---my best friend is someone with whom I've been friends for 29 years, and I obviously met him in a different place.)

So then part of the question becomes 'why' have these two places been so good to me in this respect. Obviously, friendships are constrained by opportunity, and I think that's the main key. It probably is true that Caltech and Oxford have more (as a ratio of total people) of the types I like, but it's not like those people don't exist at other places (and I have clearly met several of them in the past). Most of my close friends from Caltech were in Lloyd House and similarly most of my better friends from Oxford are people I know via Somerville. I don't know anybody in the Mathematical Institute that well (it's more of a colleague thing there, though I certainly like my colleagues very much), and I only know one person from the complex systems group at any reasonable level.

The number of good friends I've made here is admittedly smaller than after the same amount of time at Caltech, but I believe that the difference is that back then we were basically all thrown into close living quarters and that is different from my living arrangements here. But here I have excellent opportunities to meet wonderful, interesting people with whom I enjoy spending time. At Cornell and Georgia Tech, I really struggled to do that, and I would literally sometimes go multiple months between going out with other people. (At Berkeley, I just hung out with people I knew from before.) Here I am hanging out with my friends all the time (though, of course, Upper and Lower Crotch haven't been duplicated), so life is good.

I still get moody and even depressed at times, but that's who I am. But a couple of the locals are really looking out for me, so this entry is for you.

(Well, I'm not sure if I phrased my feelings eloquently, but I hope I got the point across.)

Congratulations to Caltech's Class of 2009

Today is Caltech's 115th commencement ceremony, which is honoring the class of 2009. Several of my former research students are among those who are graduating, and Nobel Laureate Stephen Chu is the speaker (that's a pretty good choice, actually). Congratulations!

A Unified Quantum Theory of the Sexual Interaction

Justin e-mailed me a recent blog post (on a blog called "In the Dark") that posits A Unified Quantum Theory of the Sexual Interaction.

Reaction: Um, shouldn't my article on Quantum Cuteness have been cited? :) I posted that on my website over 5 years ago. Granted, my work was purely theoretical.

Title: A model for sexed coagulation
Authors: Raoul Normand
Categories: math-ph math.MP math.PR
Comments: 33 pages
MSC-class: 34A34; 60K35
\\
We consider in this work a model for aggregation, where the coalescing
particles initially have a certain number of potential links (called arms)
which are used to perform coagulations. This model is sexed, is the sense that
there are male and female arms: two particles may coagulate only if one has an
available male arm, and the other has an available female arm. After a
coagulation, the used arms are no longer available. We are interested in the
concentrations of the different types of particles, which are governed by a
modification of Smoluchowski's coagulation equation -- that is, an infinite
system of nonlinear differential equations. Using generating functions and
solving a nonlinear PDE, we show that, up to some critical time, there is a
unique solution to this equation. The Lagrange Inversion Formula allows in some
cases to obtain explicit solutions, and to relate our model to two recent
models for limited aggregation. We also show that, whenever the critical time
is infinite, the concentrations converge to a state where all arms have
disappeared, and the distribution of the masses is related to the law of the
size of some two-type Galton-Watson tree. Finally, we consider a microscopic
model for coagulation: we construct a sequence of Marcus-Luschnikov processes,
and show that it converges, before the critical time, to the solution of our
modified Smoluchowski's equation.

Quote of the Day: Ponti's Dinner Edition

Tonight we had our Ponti's dinner in Somerville, which this year is doubling up as part of our campaign (launched this weekend) to get lots of money from our alums and other sponsors.

The pre-dinner speech was given by Chris Patten (Baron Patten of Barnes). He announced in this speech that he was going to "do the West Coast" of the United States. Clearly, he has no clue whatsoever about how that would be interpreted back home---in particular when "do" is applied to the West Coast . (Let's just say that he is evidently going to have a very exhaustive trip---especially if he plans to visit Hollywood.) Wow.

In another bit of "awesomemess" (and in this case I definitely mean this term in a derogatory fashion), one of the fans at Dodger Stadium today (I turned on the game when I got back to my apartment) was wearing a t-shirt that had the terms "the man" and below that "the legend". Above "the man" was an arrow pointing up. Below "the legend" was an arrow pointing down. I think the word of the day for this one is probably "overcompensation". Or perhaps just "awesome".

I'm not sure if this one requires any commentary.

Steve Strogatz on Networks and the Phillips Machine

I had never heard of the Phillips Machine, but there is a refurbished one at Cambridge that "works". As Steve Strogatz explains in his latest guest column in the New York Times, it's basically a miniature hydraulic caricature of the economy. The article then relates this briefly to some modern work in networks and complex systems, more generally bringing up the point that one of the really exciting and challenging things of these subjects is the attempt to move beyond reductionism.

From the archives (or, how I once almost made it into Time Magazine)

When I was in grad school, I saw an article in Time Magazine about mathematics and mathematicians suddenly becoming sexy, so I decided to send a letter to the editor. My letter almost got printed.

It's worth noting that I wrote this letter before I started studying granular chains, for which one of the most important elements is the stiffness of one's balls. (Acoustic waves travel faster in stiffer materials.) Also, Techers will recognize a bit of this from back in the day...
