Font Battles and a Childhood Fascination with Fonts

According to Sang Hoon Lee, the journal club for our collaborator Beom Jun Kim has devolved to include font battles in the slides that the speakers are employing. He posted a picture on Facebook to prove it. (I realize that most of you will not be able to access that picture; I am including it here for my own reference so that I don't need to go elsewhere to look it up.)

This reminds me of something: When I was a kid, I bought the program Fontastic so that I could design fonts without going into Resource Editor (aka: ResEdit) and destroying the systems on my disks (and needing to wipe them clean) in the process. I bought Fontastic as a toy. In short: I could totally win a font battle. You can read a bit about Fontastic in the Wikipedia entry about its sequel ("Fontographer"): "In December 1984, James R. Von Ehr founded the Altsys Corporation to develop graphics applications for personal computers. The first foray by Altsys into commercial font editing software was a bitmap font editor called Fontastic, released in the mid-1980s for the Apple Macintosh. The program, developed by Altsys founder Jim von Ehr, was able to edit the native bitmap font format of the Mac."

Yes, I really was editing fonts on my computer at the age of 8. It's really no wonder that I am still very anal about such things. (None of my fonts were any good, but that's a different issue.)

Cooking Hornets

Wow, now this is pretty impressive: the bees in a colony attacked by a hornet bum-rushed the hornet and vibrated their wings to raise the temperature and cook the hornet alive. (These bees can tolerate higher temperatures than the hornet.)

Bill and Ted and Their Quantum Computer

When I saw the picture associated with this post, the first thing that came to my mind was the quantum computer saying "69, Dude!" when asked about its favorite number.

I Want Labeled Axes!

I want labeled axes --- or possibly a giant sign for his door that says "Label your fucking axes!"

Misinterpretations are also welcome.

(We'll see if there are some labeled battle-axes or something similar waiting for me when I return to Oxford.)

As Rachel Gray points out, there is an an appropriate xkcd for the occasion that involves ending relationships and lack of axis labels. There is also another strip --- I think it might also have been xkcd? --- about putting snarky labels on any unlabeled axes submitted by students. I saw this a couple of years ago, and I might add a link to it later. (I looked briefly just now and couldn't find it, and I don't feel like looking more at the moment.)

2014 Nobel Peace Prize

The 2014 Nobel Peace Prize has been awarded jointly to Kailash Satyarthi and Malala Yousafzay "for their struggle against the suppression of children and young people and for the right of all children to education."

As noted in the CNN article covering the prize, there is significant design in the sharing of the prize of these two individuals from disparate backgrounds and beliefs (and from ones that have often come into conflict with each other).

At age 17, Malala Yousafzay is the youngest ever winner of the Nobel Peace Prize (and I would assume of any Nobel Prize, though the article neglects to mention this). I absolutely love one of the side tidbits in CNN's article: "Pakistan's Malala Yousafzai will give her first statement after school".

How Many Assholes Are There On This Paper?

I knew it! I'm surrounded by assholes! (Yes, really.)

On a similar note, you can also read about an application of the "BS method" on the arXiv today.

Update: Improbable Research has now posted a blog entry about this.

Update (10/14/14): Improbable Research has posted an update about the story.

Caltech Math: Where One Goes to Learn "Topography"

Caltech's undergraduate mathematics has been listed as 10th best in the United States according to some way of ranking these things.

I don't really care about that (because such rankings are only worth a little bit anyway), but there is a choice quote in the article when it comes to Caltech: The Department of Mathematics at the California Institute of Technology offers an undergraduate program that introduces students to theories and principles of math, while strengthening problem solving and analytical skills. Classes in algebra, statistics, linear equations, discrete mathematics and topography build over the course of the program.

Why isn't the applied mathematics (which has been called "Applied and Computational Mathematics" for many years but was still called "Applied Mathematics" when I went there) even mentioned? I've obviously biased, but clearly I favor the applied mathematics major at Caltech over the mathematics major.

Now, if you will excuse me, I am going to go and practice my topography.

Jeffreys, Jeffreys, and Logarithms

My host (Marc Feldman) was trained originally as a mathematician, and there are a bunch of mathematics books --- he apparently doesn't use these anymore --- are in the office I am occupying.

There are a couple in there that I have interest in browsing through. For example, I was just looking a bit through the mathematical physics book by the infamous Jeffreys and Jeffreys (3rd ed, 1953). I like the following footnote in the chapter on asymptotics:

"Actually, of course, we should work out 100 log_{10} e and then evaluate by means of a table of logarithms to the base 10. When a multiplying machine is available two uses remain for logarithms to base 10; to work out high powers and logarithms to base e of large numbers."

Anyway, I enjoy the need to explain in 1953 (or earlier, if this comment predates the 3rd edition) that there are still some uses for log base 10.

Thesis-like Objects

I think that the term "thesis-like object" ought to be in standard academic usage. That is all.

Another Victory for The Onion: Education Edition

Wow, The Onion has scored yet another victory with this scathing article about education. I don't agree with what appears to be the underlying opinion of whoever wrote the article, but I still enjoyed its scathing humor. I don't think it's all doom and gloom, though: I genuinely think that one can reach students who are from the wrong side of the tracks or have other difficulties to overcome. (I do happen to believe a great deal in outreach and in attempting to inspire people.) At the same time, one shouldn't be naive and think that inspiration itself is enough, so it's not like there aren't any relevant implied points in this article.

Update: Thinking about this further, maybe the point of the author is that we should get behind all of our students --- and that is something with which I agree wholeheartedly. I was reading a more insidious message (i.e., not bothering with the difficult cases) into what I thought the author was suggesting, but maybe I was misreading the underlying opinion?

Nobel Prize in Physiology/Medicine Awarded for Work on the Brain's Navigation System

This year's Nobel Prize in Physiology/Medicine went to a trio for their work on the brain's navigation system. It's also great that neuroscience (and systems neuroscience, no less) was recognized with a Nobel.

A particularly relevant Scholarpedia entry is the one on grid cells (which, along with "place cells", help the brain to determine where it is and where it is going), whose authors --- a team of wife and husband --- comprise two of the three newly-minted Nobel Laureates.

Now about my horrible sense of navigation...

Update (10/10/14): I neglected to post the official announcement.

Here Comes the (Smell of) Rain Again

In case you are curious, here is a very brief primer on the origin of the smell of rain.

A City Named "Boson"

Note to self: the airport to which I want to fly is in the city of "Boston", not "Boson".

My search will probably be more effective now. And the best news of all is that more than one person can occupy that airport at once.

Omar Vizquel and Asymptotic Scaling

I think I just found my new favorite Wikipedia easter egg: "Little o" redirects here. For the baseball player, see Omar Vizquel.

Yes!

What Happens in Goleta Stays in Goleta

I flew into Santa Barbara yesterday to give a talk called Cascades and Social Influence on Networks at UCSB yesterday. It's been a fun visit!

Krukow and Kuiper

Giants broadcasters and former Major Leaguers Mike Krukow and Duane Kuiper are the second-best broadcasting team in Baseball right now. (The only one better is Vin Scully, who is only the best sports broadcaster ever.) I often make it a point to listen to them, and I have frequently chosen to watch Giants games over other non-Dodgers games in order to listen to them. They are excellent, and here is an interesting article about their friendship and about the significant physical challenges that Mike Krukow is facing because of a rare disease.

"Anything You Can Safely Bury in Your Backyard"

Today I finally noticed Stanford's guidelines for what you should compost: "Anything you can safely bury in your backyard"

Well, I don't know about you, but my mind has just gone in very bad directions...

Visualization of a Career

Here is a very cool (and rather intricate) visualization of the outcomes of Derek Jeter's plate appearances throughout his career. (The data comes from the usual sources, and the graphics are by a company called Chartball. I might well want to buy a poster from them about my team, my favorite players, or something else interesting.)

Stung!

I think I just literally experienced the sharpest, most intense physical pain that I have ever had in my entire life (and my fingers were once slammed in a car door, so that's saying a lot).

I was walking merrily along to get a smoothie for lunch, and some insect stung me horribly in my right pinkie right in the bottom spot where I bend it. The stinger went all the way through and poked another (smaller) hole through the skin farther up my finger.

I ending up apologizing profusely for my salty language to the two nice ladies who stopped their walking to ask me what was wrong.

That was close to 30 minutes ago, and my hand is still shaking a bit (and I can't make a firm fist, and it really shakes when I force myself to make a fist). And it still hurts like Hell, though not as intensely as during the heated moment. The pain is very slowly dulling.

I hope that insect dies a slow, painful death (maybe nailing me was its last act of defiance?), and then I hope it gets experimented on. I know biologists --- I could make this happen.

I have been stung before --- on the bottom of my foot, even --- and it was nowhere near as painful as this time.

As some of you know, I have a history dating back to not just my Caltech days but all the way to Beverly Hills. (I never did get stung by one of the Caltech hornets, even though they harassed me a lot.)

My smoothie was well-earned.

In conclusion: Ouch. And Fuck.

Quantum Espresso

I am on the mailing list for The Abdus Salam International Centre for Theoretical Physics, and I recently received an e-mail from that advertises an upcoming conference with a very compelling acronym (ESPRESSO).

Here is an excerpt from the e-mail: In collaboration with the Quantum ESPRESSO Foundation and CECAM, the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy, is organizing an Advanced Quantum-ESPRESSO Developers' Training Workshop to be held in Trieste from 19 to 30 January 2015.

What, so classical espresso is no longer good enough?

Academics Write Like Crap

Well, at least most of us write like crap for our academic writing. Additionally, most of us don't include humor in our scientific articles either.

I do the best I can to buck this trend, though others will be the judge of how well I do. I certainly attempt to put humor in some of my writing, and quite a few of my papers (e.g., this one) contain easter eggs. I do think that I am a good writer, and at minimum I am definitely very anal about my scholarly prose.

Although I don't agree with everything in the article about what we do that is bad --- for example, I think the paragraph with "The rest of this article is organized as follows." is genuinely useful for many readers, especially if the article is long --- but I agree with a lot of it. Also, I can't overemphasize how much my scientific career has benefited from my experience in journalism at Caltech. (Yes, being a Tech Editor has been amazingly beneficial. It's one of the best and most important things I did for my education.)

Even More Average Than Before?

Former Major Leaguer Gabe Kapler offered some astute analysis about the Giants' playoff chances: "The loss of Pagan makes an already league average offense more average."

In related news, I subtracted 0 from 0, and I still have 0.

Note: Pagan's injury is a very big loss. Kapler had a sensible point in mind, but the way he phrased it is "fantastic".

The Smell of Old Books (and of New Video Game Systems)

Have you ever noticed the smell of old books? One researcher described it as follows: a combination of grassy notes with a tang of acids and a hint of vanilla over an underlying mustiness, this unmistakable smell is as much a part of the book as its contents.

On a similar note, I also have always noticed a distinctive smell when I get a new video game system. Yummy!

Headline: Sudden Execution Causes Extinction of Matrix Products

Here is a quote from a paper I finished reading this morning: "We first execute the last matrix product..."

Well, damn. Now I guess matrix products have become extinct. Cruel bastards.

Induction and Birthday Parties

Well, this is a very depressing way to apply induction.

I find this SMBC perversely amusing, though I have been in this kind of situation before and it's not fun.

More Retiring Baseball Players

Recently, I blogged about Adam Dunn's likely retirement. Understandably, Derek Jeter's retirement tour has gotten most of the major headlines --- and deservedly so. And as much as I can't stand the Yankees (and sometimes get annoyed by all of the jeterating), Jeter deserves immense respect, will make the Hall of Fame in a first-ballot landslide, and I love it that his last game at Yankee stadium had a storybook ending. I'm also not surprised that the The Onion has had a series of articles during the last week poking fun at Jeter. (They have a history of doing that, like the time that I discussed in this blog entry.) I also want to bring up Paul Konerko, who has also has had an excellent career. (When Konerko was a prospect, the Dodgers traded him for Jeff Shaw. Sigh.)

Well Done, Onion: Infernal Edition

I somehow missed this article that The Onion published last year as a satire of homosexual people being condemned to eternity in Hell. This has apparently done wonders for the lifestyle down there.

Four-Sided Polygons: Basically a Rehash of Triangles

I really like today's SMBC about a website in which you can post reviews on anything.

My favorite is one of the reviews of 'four-sided polygons': meh. basically a rehash of triangle.

How The West Was Won

The Dodgers beat the Giants tonight and are now officially National League West champions for 2014!! Tonight we were led once again by Clayton Kershaw, who right now is the best pitcher on the planet.

Go Dodgers!!!!

Spectral Graph Theory: Cover Art

Here is my new cover art for the field of spectral graph theory. (I couldn't wait until Halloween to make this picture.)

The Laboratory Safety Dance

The guy who gave me the key to my office wanted me to undergo a minicourse in lab safety, but thankfully I was able to talk my way out of it. (This is one of the perils of sitting in a biology department.)

Fun Fact: When I was a frosh... I broke so many things in the digital electronics lab that the department changed the policy after me so that future students had to pay for what they broke. I had a collection of the broken items taped to my door in Lloyd House.

Weird Al and Weird Mason

I have pretty much the same hair as Weird Al Yankovic. Just sayin...

"Big Data" is a Religion

As far as I can see, "Big Data" seems more like a religion than anything else.

I like "Good Data" (which is far from the same thing) and "Good Models" (which can, e.g., include parameters fitted from data). I feel like I have a chance to actually understand things that way.

Data analysis definitely has its place and I certainly also have my moments when I do data analysis (see some of my papers), but data is far from everything. In short, I have ambiguous feelings about "Big Data".

Anyway, data analytics is an approach, and I use it sometimes, but there are also many other approaches that one should pursue to try to understand phenomena and solve problems.

By the way, I first posted the picture to which I link above in this blog entry, I ranted a bit about it in this blog entry, and I talked about a Small Data project at ECCS in 2013. (That work I described in that talk has subsequently been published in PNAS.)

Live Action Paper Mario in the Best Western?

"I Deserve a Fucking Cookie."

I had a long and tiring flight and then a rather ornery cab driver (and, of course, the website that estimated the taxi fare was off by a factor of about 2.5).

At least the hotel's reception has complimentary cookies at the front desk --- so to quote one of my esteemed Oxford colleagues, "I deserve a fucking cookie."

Humorous Grammar Lessons

Yes, indeed.

Have I Gotten Stuck in a Mirror Universe?

I think I might have accidentally entered a mirror universe: a store that was a Starbucks just a few days ago has now turned into something else.

Surely that is one of the strongest signs that one has ended up in a mirror world?

2014 Ig Nobel Prizes

The 2014 Ig Nobel Prizes were awarded last night.

The clear winner among this year's awards is the Economics prize, whose citation is as follows: ISTAT — the Italian government's National Institute of Statistics, for proudly taking the lead in fulfilling the European Union mandate for each country to increase the official size of its national economy by including revenues from prostitution, illegal drug sales, smuggling, and all other unlawful financial transactions between willing participants.

I also really like the prizes in Physics, Neuroscience, and Biology. (As concerns the Pyschology Prize, maybe I should point out that I am a night owl...?)

Rescheduling my November 31st Talk

I just realized that I committed to give a talk on November 31st, which was subsequently confirmed by the host institution. I think I'm going to have to reschedule...

(Yup, the day still doesn't exist. I guess that explains why the November 31st slot was still available?)

I think that this was quite an achievement in "awesomeness", even by my lofty standards.

"(Then again, it may not.)"

One of the new papers on the arXiv today has an abstract that ends with the following sentence: "The work may shed light on the possible properties of different ensembles of mixed systems."

Whenever I see a sentence like that to end an abstract, I automatically think about the implicit "(Then again, it may not.)" sentence that naturally follows as the next sentence.

Update (9/19/14): This also applies to sentences that end conclusions.

2014 MacArthur "Genius" Awards

The 2014 MacArthur Fellows (i.e., the so-called "genius awards") have just been announced.

And I am super excited about them this year, because my coauthor Dani Bassett is one of the recipients! It is, unsurprisingly, richly deserved. (At age 32, she is also the youngest of this year's Fellows.) The work in which I was involved is cited among her major contributions --- especially this paper and several follow-ups. Major congratulations to Dani!

A couple of mathematicians are also among this year's winners, and of course that always makes me happy. (Among the mathematicians, it is particularly cool that Yitang Zhang won because of his career path.)

Pictures from Göttingen

Here are some pictures that I took during today's excursion from the conference.

What Happens in Göttingen Stays in Göttingen

I am now traveling to Göttingen for a workshop in ecology and "networks on networks". The program, which was sent to participants yesterday, makes it looks much more like a conference than a workshop.

Academic Rookie Cards

Today's SMBC is a big win! Creating academic rookie cards is an excellent idea, and I love the snarkiness in the associated joke that SMBC told. I approve!

P.S. I am listening to the closing theme of "This Week in Baseball" right now. How appropriate!

Mathematicians and Justice

Oxford currently has a photography festival that is spread over many buildings in the city.

The two themes that we're housing in the Mathematical Institute are "Mathematicians" and "Justice".

The punchline is left as an exercise for the reader.

Grandpa and Grandmaster Flash

Through the magic of autocomplete, many grandmothers have been accidentally tagging rapper Grandmaster Flash on Facebook. I love it!

Like Grandmaster Flash, the Grandmas had no part in the song "White Lines".

Adam Dunn and the Three True Outcomes

Adam Dunn is almost certainly going to retire after the 2014 season is over. He is currently third all time in strikeouts among hitters, and he's only 34 years old. He would only need to play a couple more seasons to set the record.

Jayson Stark wrote about Dunn's career today, and some of the numbers are mind-boggling (like how often fielders weren't particularly needed when he came to the plate). Amazing.

Update (10/01/14): It's now official (and unsurprising): Adam Dunn is retiring. He is on the Oakland Athletics, who just lost to the Royals last night in the AL Wildcard one-game playoff. This season was the first time that Adam Dunn got into the playoffs (after more than 2000 games played, which made him the active "leader" in that category), and he didn't even get to play in the game.

Being Part of the Story of Science

When you are an undergraduate student, and for the most part when you're a graduate student (though it starts to change then), you read scientific and mathematical results that have been neatly polished and compiled into books --- and then somewhat less neatly polished and compiled into papers. You probably will see that there are many mysteries left to uncover, but it's still knowledge and somehow something that already exists. And then you become a scientist (and mathematician) and you realize that there are stories --- often very interesting ones --- behind the knowledge and that can occasionally be just as fascinating (or even more so) than the knowledge itself. It's not just that some of the personalities are genuinely interesting (though that is also true) but that the path to knowledge is typically a maze of twisty little passages, all alike --- and there are a lot of inside jokes and events that become part of the stories, and these jokes and stories often have many layers (pun intended).

Being a professional scientist isn't merely about creating new knowledge (though that definitely is part of the deal). It means that you're part of an ever-enfolding story that people outside can watch and appreciate, but you are actually in the story, because you're one of the people helping to create it.

And let me tell you: It is incredibly awesome being one of the players in this evolving story! It's hard to beat being part of that, and I can't imagine trading it for anything.

So the next time you open a math book and see a theorem (or some other important or maybe not-so-important result), remember that that theorem might well have an interesting story behind it. It's more than just a piece of deductive reasoning. And, obviously, the same goes for all other scientific discourse. :)

And what made me think of all this particularly poignantly right now? Ergodic clams, of course. None of the thoughts above are new to me (I have had them many times, in fact), and I'm sure that I could have phrased them more eloquently, but I have to thank Petter Holme and Sang Hoon Lee for the immediate inspiration for writing this post when I should have gone to bed instead.

Now I better start thinking about what my theme song should be...

Hmmmm.... I Think Oxford is a Cult

If you think a bit about this comic from SMBC a bit, it does kind of make one ponder the possibility that University of Oxford is a cult. There does seem to be some level of truth to that perspective.

Ten Books

Over the past couple of days, I was seeing a meme over Facebook to name 10 books that have stuck with you for whatever reason. This meme seems more interesting to me than most, and I was tagged today, so I decided to play along.

The rules are as follows: In a text post, list ten books that have stayed with you in some way. Don’t take more than a few minutes, and don’t think too hard---they don’t have to be the "right" or "great" works, just ones that have touched you. (And because it says "books" rather than "novels", I decided to include some math and physics books, because that is part of what came to mind. I also included some other possibly "nonstandard" choices, but I could try to come up with a list that is pure fiction if you want. :) )


Here are 10 books (in no particular order), but numbered for convenience:

1. Introduction to Nonlinear Dynamics and Chaos, Steven H. Strogatz

2. The Dragonlance Chronicles (original trilogy; you could possibly include Dragonlance Legends as well), Weis and Hickman

3. Dark Elf Trilogy (especially Homeland, which is the first book), R. A. Salvatore (3 books again)

4. Manual of the Planes, Jeff Grubb (1st edition AD & D sourcebook)

5. Hitchhiker's Guide to the Galaxy (and its sequels), Douglas Adams

6. Shōgun, James Clavell

7. Noble House, James Clavell

8. The Scouting Report/The Scouting Notebook series of yearly baseball previews (may they rest in peace), by Stats Inc. in some years (with writers John Dewan and others)

9. Thermal Physics, 2nd ed, Kittel and Kroemer (this was my first statistical mechanics textbook, from Ph 2c at Caltech; I found it really inspiring to start from counting and to derive things like temperature)

10. Rotisserie League Baseball: The Official Rule Book and Draft Day Guide, various yearly editions, Glen Wagonner, Robert Sklar, and others.

"99 Red Balloons" Covered with Red Balloons

Yup, yes it is.

New to the Blogroll: Bruggebrain

Through the magic of e-mail signatures, I noticed that my doctoral student Birgit Brüggemeier has a blog. She studies neurogenetics, and is working on an awesome project. You can read about what she studies on her page.

At some point, I should also delete the blogs on the blogroll that are no longer being updated, but for now I'll let you --- dear reader --- scroll just a little bit more. That is what Janis Joplin sang about, right?

Community Detection and Scottish Independence

A few years ago, I read a very interesting paper that is rather topical when it comes to the issue of Scottish independence.

The final sentence of the abstract reads as follows: We also quantify the effects of partitioning, showing for instance that the effects of a possible secession of Wales from Great Britain would be twice as disruptive for the human network than that of Scotland.

The methodology in the paper is "community detection" --- a type of clustering --- applied to networks constructed from mobile phone data.

Technology Translation

So.... can anybody translate what a funding agency means when they write "Describe the empowerment of new and high-potential actors towards future technological leadership."

Seriously, WTF. I read that, and my mind just goes "[tech] [tech] [tech] [tech] [tech] [tech] [tech]" like in the script for a sci-fi movie.

I had a ton of problems with just the buzzword version of the word "disruptive", which seems like child's play compared to the sentence above.

Quote of the Day: Referee Request Edition

Well, I haven't used this line in my decline letters (at least not recently) because maybe it isn't the kindest thing in the world to write, but there are certainly times when I want to end my e-mails declining a request like this: Please also make it clearer in the future what method of communication you would like from me for declining review requests.

To give some context, I consider it exceptionally obnoxious when somebody asks me to referee something on a short timescale and assumes that I will accept the reviewing assignment. It's a very poor assumption, and in fact it increases by a rather substantial margin the chance that I will decline the request.

It would be good, by the way, if every such request automatically included the procedure to decline and not just the procedure to submit a referee report.

P.S. Get off my lawn!

Gaussian Curvature and its Practical Consequences

Wired has a very cool article about manifolds and curvature.

I have used ice cream cones (and the act of unrolling them) to help explain curved versus straight geodesics for one of the problems our student had to do in calculus of variations. I then "assigned" my students to do this the next time they went to the local ice cream place.

RIP Joan Rivers (1933–2014)

Joan Rivers, a comedy legend, died today.

I don't remember when I first heard of her, but it was a long time ago, and vastly predates when I saw her in 1987 in Spaceballs, where she played the voice of Dot Matrix (who is, roughly, analogous to C3PO). That's her role that I know the best (by far), and my favorite quote of hers from that movie is the following one: That was my virgin-alarm. It's programmed to go off before you do!

Polymeric K_{3,3}

Some chemists have now constructed the graph K_{3,3} (and other tiny graphs) out of a polymer, and they seem to want to go after Königsberg next.

In related news, I think the South Side (aka: applied and related) of the Mathematical Institute now should annex the North Crystal, which just so happens to have a K_{3,3} graph as its vertices and edges.

(I'll be truely impressed, however, when somebody successfully constructs the ZKK graph using such polymers.)

Best Pitcher on the Planet

Well, first of all, Clayton Kershaw is the best pitcher on the planet right now, and he's really showing this year that he truly is one of the all-time greats.

We saw a bunch of that before, but he's really taken things to a new level. I hadn't realized this until last night's Dodger broadcast, but Vin Scully mentioned that Bryce Harper's homerun against Kershaw during Tuesday's game against the Nationals was not only the first homerun by a left-handed hitter against Kershaw this year but it's also the first RBI of any kind against Kershaw by a lefty this year. Holy shit! I looked at Kershaw's 2014 stats late last night --- and, in particular, his separate stats against righties and lefties --- and indeed this is true. Spectacular! (Note that the game recap to which I linked mentions the fact about Harper's HR but not about the RBI that went with it. The latter is considerably more impressive.)

It's so awesome having Kershaw on my team! Hopefully, he'll get not only the National League Cy Young Award this year but also the Most Valuable Player Award. (Right now, I think Giancarlo Stanton is a slightly better choice for MVP than Kershaw, so we'll see what the rest of the year brings.)

The Basis of a Good Outfield

An article tagline that I would love to see in a newspaper: "Jayson Werth, Bryce Harper, and Denard Span form the basis of a solid Nationals outfield."

Sadly, I doubt most newspapers like linear-algebraic jokes as much as I do. Maybe an independent newspaper?

Tales from the ArXiv: Herbivore Meltdown

I love the main label of the caption of Figure 5 (on page 12) of this new paper. It starts with the bold text "Meltdown of the herbivores." I love it!

Anyway, the next time you go into a forest, be very careful in case of herbivore meltdown. (I have all sorts of wonderful images in my head at the moment.)

And googling "herbivore meltdown" yields the fact that "ecological meltdown" is actually a standard term. It's certainly very image-provoking. I have to say, though, that I also find the term very humorous, even with its very serious implications.

Mathematical GIFs

These mathematical GIFs are sweet.

Invertible Yogurt

The yogurt that I had on Saturday successfully passed the Invertibility Test* (that is, it was invertible), so I knew that it was safe to eat.

* The Invertibility Test (tm) is especially important for milkshakes, as passing this test is the only way to ensure that they are safe to consume. (For other food items, the only way to pass this test is to not be invertible.)

For more about invertible milkshakes, see Legends of Caltech III and also one of its web-only stories.

Here is a really awesome spoof trailer for a one-dimensional version of The Transformers. Awesome!

My favorite line is the one about from one end of space to the other.

"Objecting Function"

Fun Fact: "Objecting Function" is not the same thing as "Objective Function".

I am waiting for this function to complain about the fact that multiple algorithms use it before it's been defined in the paper. (Well, I am going to complain about that one even if the function doesn't.)

It's a draft, but it's a fun typo nonetheless. I have certainly done more than my share of amusing word substitution. (It's good to have fun with it, and it's also good to catch it before we submit the paper and upload it to the arXiv.)

Update: I fixed another amusing typo in my draft ("asses" -> "assess"), and I am reminded of my favorite typo that I ever saw in a draft. This was a draft written by one of my Georgia Tech students, and it referred to "consecration" of angular momentum. I find this all the funnier because it occurred in Georgia.

Which Yiddish Word Describes Me?

You can check your own personal Yiddish word for yourself. I got "meshugene". [[whistles]]

By the way, I phrased things the way I did in the paragraph above because today is the 25th anniversary of the release of the song Personal Jesus.

The Onion Wins Again: GOP Edition

Yup, The Onion wins again. Hilarious!

The Rise of Nature

Charles Day writes about Rutherford, Bohr, and the rise of the journal Nature.

Damn you, Rutherford. :) What a monster you wrought.

(To be fair, this did make a lot sense in the context of the times, but I continue to be dismayed at what this has evolved into.)

Not in Academia! Never!

Surely we would never do anything like this in academia... Oh wait.

Rainbow Eucalyptus Tree

IFLS reminds me of the rainbow eucalyptus tree, which is the most colorful tree in the world! I would love to see one of these live. In the meantime, go to Google Images for some very pretty pictures.

Headlines and the Name Game

Sometimes, somebody has a last name that makes a headline awesome. No umlaut, but this headline from today's Beverly Hills Weekly is still pretty damn good.

Update: This of course reminds me of a certain scene in a certain Mel Brooks movie. (And while I'm thinking of that movie, don't forget this scene.)

Harmonographs

A harmonograph is a drawing device that is constructed of coupled pendula. Here are some instructions for how to make one based on triple pendula. Oxford's Museum of the History of Science apparently houses this one, although it wasn't there the last time I visited. I also remember seeing something along these lines (or maybe it is even an example of one?) at KITP.

And, of course, this automatically makes me think of the Spirograph drawing set that I had as a kid.

Editable SMBC?

I want an editable version of this SMBC to inflict on my buddies in complex systems...

(And I am going to be good and get some work done and then read a bit of a novel instead of opening up graphics software.)

Things People Say

In case you haven't ever checked out my quotes page, you might find some amusing things there.

Like this classy one: "If I do that, do I have to talk to you again?" (Me, on the phone with Expedia customer service, 9/17/10)

More Sobering Statistics

The Onion wins again: apparently, 79% of statistics are now sobering. As Todd Snider likes to sing (in Statistician's Blues), "75% of all statistics are made up right there on the spot."

The tagline for the article from The Onion, which reports on fake results out of MIT, quotes a scientist as saying "We found that there are very few, if any, encouraging statistics left."

Indeed.

A Colorful Stranger Alighted on my Doorstep

And here it is.

What Happens in Limerick Stays in Limerick

I'll be flying to Limerick tonight for a grant meeting tomorrow. In honor of my trip, I present the following:

There once was an Oxford professor.
Who wasn't much of a confessor.
When his rigor was pondered.
He said his mind wandered.
But at least he was a possessor.


(I think the last line could be better, but I didn't exactly spend a long time on this.)

Update: "Assessor" would also work (and give a slightly different flavor) instead of "confessor".

Human, Meet Nonlinear Oscillator. Nonlinear Oscillator, Meet Human.

Yes, really. The title of the paper was a bit odd (because of the stress on "social" interactions via the 'human dynamic clamp'), but this idea looks very cool!

A Very Short Paper Title

Wow, now that is a very short paper title: 'Q', just 'Q' --- which represents 1 divided by the attenuation factor (not modularity and also not Q).

Sociologist Jim Moody once submitted a paper called "Titles" to a journal. He was trying to get a one-word title, but that didn't fly with the journal, so he switched the title to something very long. (I e-mailed Jim to ask him for a link, which I will provide once I have it.)

The shortest title (in terms of number of words) that I have used in a paper is two. That occurs in http://people.maths.ox.ac.uk/porterm/papers/multilayer_review-published.pdf this paper. It broke my previous record of 3 words. Now I need to try to write a paper with a one-world title. I don't think I'll ever get down to one letter.

Update: Jim sent me a .pdf of his paper. It turns out that the story I heard about the title being hugely long isn't true. Rather, his paper is called "Trends in Sociology Titles", which is accurate but doesn't have the same effect as going overboard.

Back in the Day: Spring 2001 Penn State/Maryland Dynamical Systems Conference

The recent announcement of the Fields Medals brought me to thinking back at the 2001 Spring Maryland-Penn State dynamical systems conference.

In addition to the schedule --- which included somebody who already had won the Fields medal, who I successfully challenged with one of my questions even though I was just a grad student; somebody else who would win one later; and several other speakers who I met for the first time at that conference and would see many times since over the years --- there were also other people (like Howie Weiss) in the audience with whom I would subsequently interact a lot over the years. This also includes several people from University of Maryland (such as Brian Hunt, who was one of the conference's main organizers), though I am pretty sure that Jim Yorke wasn't around for that conference. (I would meet him many times later.) One of my friends from Caltech also attended the conference, and several audience members who weren't speakers also have moved on to bigger and better mathematical things.

I also vaguely remember that audience-member Misha Brin (who was not yet known as "Sergey's father" at the time) was not particularly fond of the research that I presented in my talk, though I'm not really sure whether that was just his mannerisms or his actual opinion.

Several of the attendees who were still doing rather pure work then are now rather applied in most of their work. (Or have even become famous entrepreneurs in the tech world. :) ) Given what people have done since that conference, it's a rather impressive selection of speakers among the people who hadn't yet "made it" at the time.

Gorgeous Mathematical Sculptures

Eric Standley's mathematical sculptures are absolutely gorgeous.

Vacation: Graduate School Style

This issue of PhD Comics about vacations in graduate school is pretty much true.

(Tip of the cap to Carlos Castillo Chavez.)

Nope, None of Them Here

I overheard the following comment in the dining hall at Churchill College, Cambridge by one the kitchen staff: "I hate really smart people who think they're above everybody else."

We don't have any such people at Oxford, of course. :)

Note: There was no comma in what she said (so it wasn't "people, who").

My 'Personal Vision'

I am giving some comments on an EU consultation for how mathematics can help with challenges in big data and high-performance computing. The sign-up section contains a long field called "Personal Vision" where we are apparently supposed to stand on our soapbox and give our grant vision. I just wrote the following:

"I like to study interesting problems."

I hope they consider that to be sufficient.

2014 Fields Medals

The 2014 Fields Medals have now been awarded. The Fields Medals are considered the most prestigious award in mathematics, though the Abel Prize is giving the Fields Medal a run for its money.

The 2014 Fields Medalists are Artur Avila, Manjul Bhargava, Martin Hairer, and Maryam Mirzakhani. Avila won for his work on dynamical systems and renormalization, so there's a victory for the home team. (Dynamical systems is part of the home team because it's one of my research subjects.) Bhargava won for his work on the geometry of numbers. Hairer won for his work on stochastic partial differential equations, and his joint work with Jonathan Mattingly was included in his prize citation. (Now I need to go give Mattingly crap for this --- just because it's fun to give him crap. I could focus on the "too old" part, though of course just about all of us in mathematics would be happy to get a sidebar mention for something like this!) His work is also in an area that has some relation to some of my interests. Mirzakhani got a Fields Medal for her work on dynamics and geometry of Riemann surfaces and their moduli spaces, and she is the first woman ever to win the Fields Medal. (About damn time. Surely there are others who could have been so recognized previously?) Dynamical systems --- including billiard systems, which I like a great deal --- play a significant role in some of her recognized work as well, so dynamical systems in its various guises and places where it makes an impact --- and it is a rather diverse field indeed --- has done rather well this year. (Statistical mechanics, which is also near and dear to my heart and which is also rather diverse, did exceptionally well in the 2010 Fields Medals, and it also reared its head among the 2006 winners.)

Update (8/14/14): My department head Sam Howison has written an opinion piece in The Guardian on women in mathematics and Maryam Mirzakhani's Fields Medal.

RIP Robin Williams (1951–2014)

Comedy legend Robin Williams was found dead earlier today (the 11th) from an apparent suicide. I'm not sure what my favorite one of his roles is, but he certainly had some memorable ones (such as Mork and in movies like Good Morning Vietnam and Dead Poets Society).

(Tip of the cap to several people via their Facebook posts.)

Update: The CNN article about Williams' death has some additional information.

What Happens in Cambridge (UK) Stays in Cambridge (UK) [2014 Edition]

I only got back from Caltech yesterday evening, and today I am taking a train to Cambridge for the 2014 SIAM Conference on Nonlinear Waves and Coherent Structures.

I have prepared a very topical slide for my talk. Be prepared. :)

It's a Meme: #HunterPenceSigns

The #HunterPenceSigns meme is pretty damn awesome. Sometimes it's bizarre what becomes a "thing", and this meme is officially a "thing". (Oh, and as you can see from the article to which I linked, Hunter Pence is handling the gentle trolling really well.)

Update (8/07/14): Here are some more Hunter Pence signs.

"Longdaysin"

I just learned (in a talk by Frank Doyle) about an appropriately-named compound called "longdaysin" because of its ability to slow down biological clocks. Even cooler than "ubiquitin". Those wacky biologists...

The Best Thesis Defense is a Good Thesis Offense!

YES!!!!!!!!

(Do you know who said that? Mel, the cook on Alice.)

And, yes, today's xkcd is a huge win.

Baseball Cup Art

Yup, the Baseball cup-art war has just been taken to a brand new level. First it was the Rockies spelling "Rox", then it was the Cubs spelling "Cubs", and now a minor league pitcher has given us a seen from Pac-Man. I approve!

Achievement Unlocked: Use the Fibonacci Sequence to Verify ID to Complete a Purchase

Achievement Unlocked: Use the Fibonacci sequence instead of an ID card to verify my identity and complete a purchase.

This evening, I found a nice practical real-world application of the Fibonacci sequence: I was buying a game (called "Pix") at Game Empire and was paying by credit card. The guy behind the counter asked to see an ID card, but I didn't have any with me. After I mentioned that the only thing I could do was to go back to my hotel room to get an ID, he decided that if I could correctly define the Fibonacci sequence that that would suffice instead of an ID card. So I gave him the correct definition, and we finished up the purchase.

(His idea came from the fact that I was using a Caltech Credit Union credit card. He wanted to make sure that card was legitimately mine. OK, I now have a nice story to tell --- which I appreciate --- but the logic was somewhat flawed. I did tell the guy that we both get an "Achievement Unlocked" for this.)

So don't ever let anyone tell you that there aren't any practical applications for the Fibonacci sequence!

Update: As Ernie Barreto points out, doing a Taylor-series approximation correctly was once a matter of life-or-death for physicist Igor Tamm. I am going to use that story when I teach Taylor series to my students.

Love, Three-Body Problems, and Chaos

Well, mathematicians certainly like to discuss love and its chaotic implications. (Remember, the three-body problem is provably chaotic.)

Post-Seminar Comments

After our applied math seminars, we have coffee and cookies (and other pastries, or "cakes" as they are known in the UK) in the common room.

Earlier this year, after a particularly frustrating seminar, one of my colleagues uttered the memorable line "I'm going to have a fucking cookie. I earned it." (We all earned it. It was awful.)

But the best (and most memorable) post-seminar piece of snark that I have ever heard occurred during my postdoc years at Caltech and came from the mouth of Catalin Turc: "His theory is retarded."
