What Happens in London Stays in London

I just made it to London for a Mathematics and Social Sciences Workshop. When I was first invited to speak at this workshop, it had the tentative name of a "Socio-math Workshop", and Google gave me a nice surprise when I tried to find a website for the workshop.

Thank you, Google. (Context: I will be a plenary speaker at a workshop on "Socio-mathematics" in November.) pic.twitter.com/ZpWUWXWwjd

A New Quasipolynomial Time Algorithm for Graph Isomorphisms

In case you haven't been paying attention, you may be interested in reading Jeremy Kun's post about the seminar covering the announced quasipolynomial algorithm for graph isomorphism. Once the preprint comes out and it is vetted, I hope the result does turn out to be genuine. Exciting times!

Headline: "Councillor who Announced Closure of Public Toilets Fined for Urinating in Street"

LOL!

Barry Simon Wins 2016 AMS Steele Prize in Lifetime Achievement

Barry Simon has won the 2016 AMS Steele Prize in Lifetime Achievement. This is richly deserved!

Barry Simon's influence on mathematical physics and numerous related topics has been absolutely huge.

(Regarding his teaching: Barry's version of freshman calculus wasn't a hit with the students, to put it kindly, but his teaching at more advanced levels is extremely good. I was one of the inaugural TAs when he took over the introductory freshman class; it was an interesting experience.)

Using "The" Before Freeway Numbers

This cool article explains why Southern Californians put "the" before freeway numbers when talking about them.

2015 Baseball Gold Glove Winners

Baseball's 2015 Gold Glove winners were announced last night.

Creating a "Urine Black Hole"

One of these years, I ought to go to the APS fluids meeting just to see talks like this.

Headline: "Old Mice Drinking Champagne Three Times A Week Navigate Labyrinths Better"

A new article in IFLS reports that mice taking champaign supplements seem to perform better at navigating a labyrinth. This leads to an obvious follow-up research question: do they also start dancing the magic dance?

Alphaville's "Strange Attractor"

I am going to have a field day with Alphaville's new album, likely called "Strange Attractor", as it opens the door for numerous jokes that combine 80s music with math and physics. At minimum, I'm sure it will be big in Japan.

Baseball's Comeback Players of the Year

Major League Baseball has announced its two Comeback Players of the Year. Prince Fielder won in the American League, and Matt Harvey won in the National League.

Cool Exoplanet Poster

I really like the exoplanet poster in this IFLS article.

Philosophical Heaven and Hell

The punchline of the new SMBC comics is awesome (especially if you know or are a philosopher).

What Happens in Philadelphia Stays in Philadelphia (Again)

I'm heading back to Philadelphia to give a lecture at University of Pennsylvania in the Warren Center for Network & Data Sciences.

Mathematizing the Alphabet

Here in the Mathematical Institute at University of Oxford, we're mathematizing the alphabet, starting with 'A' with Roger Penrose's entry on aperiodic tiles.

"An Emergent Property"

This is how I feel about many claims of "emergence" in scientific articles.

Public Lectures on M. C. Escher

A couple of weeks ago, we had really nice public lectures on M. C. Escher in the Mathematical Institute. Now, you can watch them online. Watch for the modernized version of one of Escher's famous paintings that plays a role in one of the talks.

"Granular Crystals: Nonlinear Dynamics Meets Materials Engineering"

Chiara Dario, Panos Kevrekidis, and I have written an expository article about granular crystals for the magazine Physics Today.

Twists and Turns

The people in this article are two of my friends from grad school. I have nothing else I want to say.

Takes from the ArXiv: Hydrogen π

This paper is cool (though surely someone must have done this before).

It rederives Wallis' formula for π by looking at the spectrum of the quantum-mechanical description of the hydrogen atom. (It does this with a variational computation of the spectrum.)

Ferrofluids + Glowsticks = Awesome!

Those of you who like pattern formation (or even who just like colorful things) should look at this article's video about mixing Glowsticks and ferrofluids. Sweet!

RIP Leo Kadanoff (1937–2015)

Physicist Leo Kadanoff died yesterday. He was a giant in statistical physics, condensed-matter physics, complex systems, and other areas of physics.

Several of my physics friends were posting Facebook updates about Kadanoff yesterday. I didn't write an entry yesterday, as I figured that by today there might be a proper obituary to which to link. I didn't find any, so figured I would post a note now (with a link to his Wikipedia entry) and add one later.

Here is the comment I shared on one of those posts:

I met him once when I was a grad student at Cornell. Besides seeing him give a talk (I think I saw him speak on two other occasions as well), we had a "round table" with him and students, and it was great to get a chance to pick his brain.

One major point of discussion concerned people with physics training (and, for some in the room, who would get PhDs from the physics department) applying methods and tools from physics to problems that were not physics. It was a discussion about identity crises.

(Tip of the cap to Sara Solla.)

Update: Predrag Cvitanovic posted a really cool picture from Kadanoff's 75th birthday conference.

Update (10/28/15): The American Physical Society has now posted an obituary.

Update (11/02/15): The New York Times has now also posted an obituary. The article starts with "Leo P. Kadanoff, a physicist who provided critical insights...", and of course "critical" was absolutely the right word to use here. (Tip of the cap to Ernie Barreto.)

Update (12/01/15): Nigel Goldenfeld published an obituary for Kadanoff in Nature Physics. (Tip of the cap to Sang Hoon Lee for pointing me to this article.)

Some Awesome Spurious Correlations

Take a look at these awesome spurious correlations. I have seen a similar list before --- perhaps even the same one? --- and it's possible that I ever blogged about this list at some point (though, if so, I can't find the entry). However, these plots are fantastic, so go take a look at them.

Obviously, I really like the last one, though naturally I wonder if applied mathematics degrees were included. (Now where did I put that uranium...?) I am also amused to see an apparent peak in the revenue of arcades in 2008. I am really surprised that the peak is this recent. (The data only goes through 2009, but I am assuming that arcade revenues haven't gone back up.)

(Tip of the cap to Anna Iwaniec Hickerson.)

RIP UGCS (1989–2016)

Well, from the e-mail today (forwarded to my current account from a chain that started with my UGCS account), it looks like (barring a miracle) Caltech's UGCS cluster is going to bite the dust in a few months. As Blake Jones wrote, "Alas, poor envy! I knew it well." To quote Steve Ginzburg, it's the "End of an era". Indeed it is.

UGCS has served the Caltech undergraduate and alumni communities for 26 years, but technology has moved on. Forwarding will still occur, but I assume that in a few months my "awesome" undergraduate website (from the days of "Oh, cool! I can put up a public page on this thing called the Web!") will go away. (Maybe it will be visible on an internet archive.)

Fires and Queueing

Tonight I heard a story that I think encapsulates the UK perfectly. The server at the pub noticed a fire in a trash receptacle (I think that's what it was) just outside of a Starbucks on the High Street. He went inside and asked for water to put out the fire, indicating explicitly that it was a fire. The employees at Starbucks wouldn't let him jump the queue, so he stood in line to get water so that he could go outside and put out the fire with it.

Maybe the guy was trolling us, but this is a story that I want to be true.

Pandemic: Legacy

I just read part of a blurb about Pandemic: Legacy.

Pandemic is a really good choice to try something like this out on a game. (Note that I stopped reading the article in the middle because of spoilers. I wanted to read enough to be intrigued, so I suggest browsing through the beginning to see why I think this is interesting and then stop reading.)

I did once play Risk: Legacy, and this happened. (The person who was running the game as a facilitator noticed exactly what I was doing. I was playing the false peaceful person the whole game, and then I cashed in all my cards and blitzed over the entire world in one turn while annihilating everything and everyone in my path --- and winning, of course.)

XKCD on Human Subjects

I like the new xkcd on human subjects. I am amused.

Mapping Locations with Three Words

If I matched things up correctly, my Mathematical Institute office is located at "twist.learn.curiosity" (and other nearby coordinates).

And if it's not me, then my three Ph.D. students next to me have those coordinates.

The entrance to my flat in Somerville is roughly at the location "accent.slim.inspector". (Now where was that diamond...)

(Tip of the cap to Sam Howison, who apparently now has much more time on his hands since he stopped being department head on 1 October.)

Recap of Somerville College's Ada Lovelace Bicentenary

Here is a recap from the Ada Lovelace Bicentenary that we held at Somerville College last Friday. Planning started in 2013, and last Friday was the big day.

Differential Geometry and Soft-Serve Ice Cream

On this ultimate Way Back Wednesday (#wbw), I'll go back 20 years rather than 30.

Dig, if you will, the picture*: A sophomore (second-year students, for the locals) in his differential geometry lecture, assiduously taking notes with his right hand while consuming his (stage 1, hopefully) soft-serve ice cream with cone in the other --- the very paradigm of sophistication. :)

* I don't have actual photographic evidence, even though a scene like this occurred numerous times during my undergraduacy and several times as a PhD student.

Tongue-in-Cheek Play-by-Play

In terms of style, the tongue-in-cheek play-by-play in the new XKCD reminds me very much of some of Zifnab's play-by-play over the years. (I don't think this xkcd is particularly funny, but the unintentional homage --- not that that is technically possible, as I think it's supposed to be intentional by definition --- and the resulting nostalgia are the reason I am posting a link to it.)

Tracing the History of "Tom's Diner"

Well, clearly after seeing an article about the history of the song "Tom's Diner", I feel compelled to bring it up here.

Also see the brief comment on Suzanne Vega's website.

Dunted!

This is a great word!

Especially in verb form --- I love the fact that the dull sound is part of the definition.

And I played it with 'Dex' in Scrabble. Usage: "I might not have been so soundly dunted by the paladin's mace if my half-orc had a higher dex."

Fun Fact: A dunt is the sound made by a boot to the head.

Horror or General Fiction?

When I was a grad student at Cornell, a short-lived coffee + book place in Ithaca put one of John Hubbard's textbooks in a section called "General Fiction". But maybe the Horror section would have been better?

Actually, I thought (and still think) that the book in question has some good stuff in it, but I am amused on general principles --- and the fact that it was one of Hubbard's books added to my amusement at the time.

"Women in Computing" Playing Cards

10 Years Later

Things have been so crazy lately that the 10th anniversary of my first entry in this blog has come and gone. The present entry is number 3984.

I knew the anniversary was coming this month, and I had meant to check which exact day I started. But then I got ridiculously busy and forgot all about it until I had a moment to breathe today, and then I remembered.

Tales from the ArXiv: A Population with Two Genders

The English language has reared its ugly head again.

In the paper Constrained evolution algebras and dynamical systems of a bisexual population, the authors actually mean a population with two genders (as one can see from the abstract). This is one of those cases where the direct translation of their desired word into English happens to have a very different meaning.

Vladimir Arnold on Russian Versus American Mathematicians

Not only are these comments about Russian versus American mathematicians vintage Arnold, but there is also a very fundamental truth in his comment: spending time working to produce new results versus spending time talking about prior stuff that you did.

Literature and Googly Eyes

Googly eyes definitely improve the covers of literary works.

They also improve Caltech's campus.

Trailer for Jaws 19

There is now a trailer for Jaws 19, the fake installment to the franchise from Back to the Future II. The trailer is funny; you should watch it.

(Tip of the cap to Jonathan Adams and others.)

"Parasitic Disease Scientists Win Nobel"

CNN.com's tagline to their article about today's Nobel Prize doesn't distinguish between "parasitic disease-scientists" and "parasitic-disease scientists".

The power of the hyphen. :)

What Does Probability Mean in Your Profession?

Here are some drawings about the meaning of probability in various professions.

The one for philosophy is fantastic! Several of the others are also funny.

The so-called "actual meaning" among the drawings is not correct: "definitely" requires a probability of exactly 1, and "definitely not" requires a probability of exactly 0.

I would have loved to have seen a mathematical one, as then we would need to use "almost always", epsilons, and measures.

Dodgers Clinch National League West!

With today's victory over the Giants (it was a particularly dominating performance by Clayton Kershaw), the Dodgers have clinched the National League West!!

We've now won the division three years in a row, and surprisingly this is the first time in franchise history that we've ever made the postseason three years in a row. (Hopefully, we'll do a bit better in the postseason this year than we have during the past couple of decades.)

Controlling Our Bladders Makes Us Better Liars

As I describe in my most recent blurb for the Improbable Research blog, a new study suggests that people are better at lying when they are controlling their bladders.

A Few Good Highlights from #OverlyHonestMethods

I really like the meme #overlyhonestmethods, and here are a few highlights from it.

I especially like the third one: "Reagent became became unavailable in 2002 because nobody wanted to order more and risk being added to terrorists watchlists."

What Happens in the Bay Area Stays in the Bay Area

I am heading to the Bay Area to hang out with some of my peeps this weekend!

Birds on a Wire

On the taxi ride to the airport, I saw a set of three power lines that were parallel to each other and arrayed vertically.

The bottom one had 1 bird perched on it, the middle one has 3 perched birds, and the top one had a large number of birds on it (too many for me to count).

Any ideas what the mechanism is for this? Is there a preference for height? Does it have a bit of a DLA-like flavor in that a bird lands on the first available wire from something like a random walk or Levy flight such that it's more likely to "stick" on the top one? Does anybody know if somebody has tried to model this?

Also: Mine.

What Happens in Los Angeles Stays in Los Angeles (2015 Edition)

I just arrived at my hotel in LA, where I will based for most of the next week and a half. I'll be giving math colloquia at UCLA and USC (and will be visiting UCLA during this trip).

RIP Yogi Berra (1925–2015)

Legendary philosopher (and baseball player) Yogi Berra died yesterday of natural causes.

Yogi Berra was a legend among legends and was known not just for baseball but also for his "Yogi-isms". The ESPN article above mentions several of his famous ones, but here is another one I like: "In theory, there is no difference between theory and practice; in practice, there is."

You can read more about him at his Wikipedia page.

(Tip of the cap to Gregg Schneider.)

Update: Here are several of Yogi Berra's one-liners. Here is one sportswriter's top-10 list of Yogi-isms.

Update 2: Rob Neyer has compiled some links commemorating Yogi Berra. (It includes one link that shows a headline about the death of "Yogi Bear" --- which was an inevitable boo-boo. [rimshot!])

Update 3 (9/24/15): Rob Neyer has written another piece about Yogi Berra. This piece includes a link to his old commercial for Aflac (where Yogi absolutely confounds the Aflac duck). Yogi was awesome. I can't stand the Yankees, but --- like many people who can't stand the Yankees --- still find Yogi Berra (who is very obviously most associated with the Yankees) to be absolutely awesome.

Liquid Nitrogen and Ping Pong Balls

Do you know what happens when you place 1500 ping pong balls in a container with liquid nitrogen? Take a look at the bottom video in this IFLS blurb to find out. It is really damn cool! (The top video will help prepare you for the physics.)

What Happens in Ann Arbor Stays in Ann Arbor

My next stop os University of Michigan, where I'll be visiting the Center for the Study of Complex Systems for a few days.

Many of these pictures are amazing and/or gorgeous.

Dumbed-Down Ph.D. Dissertation Summaries

These dumbed-down Ph.D. dissertation summaries are pretty amusing.

If you want to practice doing that yourself, you can use the Up-Goer Five Text Editor to help.

Computer Scientists Versus Computer Engineers

Yup, SMBC has illustrated the difference very nicely indeed.

Being a student at Caltech was like this. (Bring back the Lloyd Coke Machine!)

2015 Ig Nobel Prizes

The 2015 Ig Nobel Prizes have now been announced.

(Georgia Tech people took home the physics prize for their work on urination duration, and I also noticed a Somervillian as one of the recipients in the prize for diagnostic medicine. Also, the economics and mathematics prizes are fantastic.)

Clocks and Bombs

I like this picture.

And, obviously, I am very much in favor of people developing their scientific skills (e.g., by making their own clocks). I'm a theorist, and practical things were never my forte, but so many of my Caltech peeps got their start this way.

"As Whacky As They Come"

According to some Reddit user (with a rather unsophisticated handle), I am "as whacky as they come".

Pictures from Salina, Sicily

Here is my 2015 album of photos from Sicily.

Utilitarian Judgements

Today's SMBC is highly amusing. Also, it hits close to home. :)

Man Shoots Armadillo; Bullet Ricochets Back into his Face

This is what we call instant karma.

I first learned about this sort of thing with bullets and armadillo-like creatures by playing Super Mario Brothers.

What Happens in Malfa Stays in Malfa

I am on the airport and making the circuitous trek to the remote Mediterranean island of Malfa to give a lecture in a summer school on networks, otherwise participate in the school, get some math done in a peaceful environment, and have some granitas. Bring it on!

Evolution of Ankylosaur Tails

Some new research has shed new light on the evolution of ankylosaur tails.

Ankylosaurus has always been my favorite dinosaur. And, really, is it such a surprise that I would be into a creature that was hard to munch and defended itself like that?

As a child, I never did see a plush ankylosaurus to buy, and perhaps the people who worked at the gift shops at the L. A. Natural History Museum and the La Brea Tarpits eventually got annoyed at my asking if they had one. I was, however, very pleased when I first saw a plush dimetrodon. That was an obvious purchase.

14th-Order Differential Equations

The setup of today's SMBC takes a while, but the punchline is worth it --- and, um, way too close to the truth.

Vin Scully Will Broadcast Dodger Games in 2016!

Oh, Hell yes! Vin Scully will continue broadcasting Dodger games in 2016. Scully has been year-to-year on his broadcasting plans for several years now, and obviously I am very pleased that Vin will be back in 2016!

Evaluating Fake Lecturers

Clearly, we need to repeat a recently-published set of experiments by inserting fake lecturers into the evaluation forms that we give to students.

Here is a quote from the paper's results blurb: "Without a portrait, 66% (183 of 277) of students evaluated the fictitious lecturer, but fewer students (49%, 140 of 285) did so with a portrait (chi-squared test, p < 0.0001)."

Tenure, She Wrote

Tenure, She Wrote looks like a really useful blog by and about women in academia.

Here is the description on their website: Tenure, She Wrote is a collaborative blog devoted to chronicling the (mis)adventures of women in academia, from undergraduate to Full Professor. We’re a diverse group representing many walks of life, career stages, institutional affiliations, disciplines, and opinions.

Quantum Political Science

I love this new article in The Onion.

The headline is "Quantum Political Scientists Hypothesize Country Headed In Both Right And Wrong Directions Simultaneously", and there are also other highly amusing comments in the article.

Self-Citations of Men Versus Women

According to a new study, male scientists self-cite more than female scientists. One of the authors of the study is Carl Bergstrom, so naturally I am wondering if the paper includes a citation of a Rosvall–Bergstrom paper on community detection.

(Tip of the cap to Oxford Mathematics Good Practice.)

A Sociological "Study" of Comfort Zones

Here is an article published three years ago in The Onion about a "study" of social comfort zones. I approve!

Choice quote: "Your comfort zone is there for a reason," Gamble said. "It's so you can stay comfortable. If someone breaches that by saying hello to you, that person is the asshole, not you. Remember that."

Bumps in a Carpet

Here is my latest post for the Improbable Research blog. You'll notice that I was discussing work by a few of my Oxford colleagues.

Oldest Known Message-in-a-Bottle

Recently, the oldest-known message-in-a-bottle resurfaced. It's a really cool story---including the reasons for releasing a bunch of bottles a century ago.

This story necessitates an obvious joke that refers to The Police, and indeed the author of the article to which I linked dutifully included it.

Dice for Visually-Impaired RPGers

Take a look at this 20-sided die for visually-impaired gamers. This is awesome.

Dice: Choose Your Weapon

Yes, my main dice bag was originally purposed to contain bags of coffee beans — what could possibly be more appropriate for me?

I have lost and gained a few dice over the years, but here is the current collection. The boring lavender set is the first set I bought specifically for RPGs.

The d20s that are meant especially for fire and poison are obvious. There are one or two I can argue for acid. I ought to get one for lightning (and for ice, for that matter).

Some Curse Words: Old-School and New-School

Some of our body-oriented curse words have been around for a very long time.

Seeing these charts makes me think of George Carlin's skit Incomplete List of Impolite Words.

I think I may never think about the word "ultimatum" in the same way again. I don't remember ever seeing that usage of that word before.

Official Congratulations to Drs. Sofia Piltz and Marta Sarzynska!

My doctoral students Sofia Piltz (co-supervised with Philip Maini), who started a postdoc in ecology at DTU in June 2014, and Marta Sarzynska, who will be working at Bain & Company starting next month, both have gotten the revised versions of their doctoral theses approved in final form. Thus, they are now both officially done! Sofia's thesis is called "Models for Adaptive Feeding and Population Dynamics in Plankton", and some of her thesis work (with a couple more papers on the way) was published in SIADS. Marta's thesis is about "Spatial Community Structure and Epidemics", and you can read about some of it in this paper (whose sequel is on the way).

"I Could Go Without Smugness if I Chose To."

I choose not to.

Pictures from Dresden: 2015 Edition

Here are some pictures from my trip to Dresden last month for the multilayer-networks workshop that Alex Arenas and I organized.

"Brimstone Angels" Series of Forgotten Realms Novels

This evening I just finished the 4th book in the Brimstone Angels series of Forgotten Realms novels.

I read the 3rd book on the series last fall as part of my read of The Sundering series (which is the main track covering the transition from 4th edition Forgotten Realms to 5th edition), and I bought the first two books to introduce myself to the characters in that book. However, I decided to read the book, The Adversary, to go through the whole Sundering series (though with occasional break to read other books, such as following Drizzt Do'Urden and one or two things from other genres, as some of the books in The Sundering series weren't all that great) before getting back to the first two books.

I found that I enjoyed "The Adversary" a great deal. It was one of the best D & D novels I had read in a long time. It is well-written, and the characters are interesting --- and I also do enjoy Planar beings and politics in my novels. (I really dug the Planescape setting back in the day.) The occasional draconic swearing mixed in with the English also reminds me of Firefly, so that is a nice touch too. To keep this track going, I decided to read the 4th book first and will treat books 1 and 2 as preludes. (Book 4, called Fire in the Blood is also very good.) I'm not sure if I will get through them both before the 5th book comes out in December (and I would like to jump to that to keep the story going), especially as I want to read the next Do'Urden book that comes out next month.

Every time I go on sabbatical and have some more time or it's the summer and I have more time, if I find a good fantasy novel, I am reminded how much I enjoy them --- even though during the school year, it's hard to spend much time at all reading novels. Around the last month or so, I have tried to make it a point to at least read a little bit of a novel on most days. (It would be really nice to keep that up; it makes me happy.) I also really miss playing in a D & D campaign, so between wanting to find a way to play RPGs regularly again and enjoying a really good D & D novel, I have been thinking about D & D a lot lately (including reminiscing about adventures from days gone by, browsing a bit through some 1st edition books, etc.). I used to have so much more time for reading novels and playing D & D, and it would be really nice to recover that. I have become so busy in the last few years.

So, this is my book recommendation for the day. I think it's been quite a while since I blogged about a novel!

Anachronisms, Anatopisms, and "Anamegethisms" (or possibly "Anadiastasisms")

We all know about anachronisms (things that misplaced in time), and I looked up that an analogous word for space (anatopism) indeed exists. However, the word I really want for things like Dungeons and Dragons --- and maybe even for a convenient or possibly snarky use in mathematics --- is to be misplaced in dimension. In the context of Dungeons and Dragons, this would be something that is the wrong plane of existence.

Apparently, there isn't a literal Greek translation of the word "dimension" in the way that we would say that time and space are examples of dimensions. Of the two choices, διάσταση (pronounced "diástasi̱") and μέγεθος (pronounced "mégethos"), the latter has an analogous form as the Greek words for time (χρόνος; khronos) and space (τόπος; place), so I have chosen to use the latter. This leaves me with the word "anamegethism". (However, from my Googling, it seems like "mégethos" would translate more to "greatness", so using a term like "anadiastasism" would probably be a more appropriate way of saying that something is displaced in dimensions, even though the form of the original Greek word is different from those for time and space.)

Context (using an example that really annoyed me from a novel that I read about 25 years ago): "The kender in the Dragonlance novel whispered that their captor obviously had some orc blood, but that is a anamegethism, because orcs do not occur naturally on the world of Krynn. So even if an orc somehow got there at some point --- perhaps via spelljamming --- it still wouldn't have been something that would be construed as obvious (especially from a low-level character).

If anybody who actually knows Greek --- Hell, I'm in Oxford, so I certainly have access to experts --- will let me know if I did this right, that would be great. In fact, I am going to e-mail one now.

Update: I also very much like the notion of "displaced in greatness", even though I wasn't thinking of that when I started down this rabbit hole.

Tetris and the Reduction of Cravings

Video games compelling me to skip meals... NEVER! :P

Old-School Technical Support

Yup, I imagine that old-school technical support worked somewhat like this.

The Gaming Graveyard

Yup.

Posted by Guinevere on Sunday, July 13, 2014

(Tip of the cap to some musician who goes by the stage name of Guinevere and to somebody --- I didn't catch whom --- shared Guinevere's post to one of the Dragon*Con groups (I forgot which one) on Facebook. I tried to find a Wikipedia link for the musician Guinevere, and I am amused that Wikipedia's disambiguation page for Guinevere also includes a certain panther from Forgotten Realms.)

Pixels (Long) and Pixels (Short)

I just saw the big-screen movie Pixels (which I previously blogged about). It was fun and nostalgic, though of course very cheesy (no surprise), and it was not the disaster I was worried that it might be. I also just re-watched the short 2010 "film" Pixels (which clocks in at 2 minutes and 34 seconds), which is just as awesome now as it was five years ago. (I also previously blogged about this short film.)

The big-screen Pixels had some very nice bits of nostalgia (and good homages), though its use of a time-capsule of 1982 arcade action has an anachronism with Tetris. It also has some picky points that it got wrong --- for example, a power pellet in Pac-Man lasting way too long for how high a level was being shown. (It is also very conveniently ignored the fact that Donkey Kong has patterns by simply pretending that it doesn't.) The character Q*Bert amused me on a couple of points, such as being there to dodge barrels amidst a level of Donkey Kong. And also the litter at the end.

For some movies that are both awesome and bring out major nostalgia for 1980s video games, I highly recommend The King of Kong and (obviously) Wreck-It Ralph. I previously blogged about The King of Kong, but I couldn't find a blog entry about Wreck-It Ralph, so I assume I didn't do it. (I blog much less often about movies than I used to --- even when they're awesome. Wreck-It Ralph even included a theme song written by Buckner & Garcia! Now that made me feel really nostalgic!)

Ludicrous Spelljamming

Kit Yates has come up with an excellent suggestion: To help combat stereotypes, mathematical scientists should tweet a picture of themselves with the #realfaceofmath hashtag. I approve! (Not that my picture will end up helping to combat the stereotype...)

(Tip of the cap to Oxford Mathematics Good Practice.)

Update: OK, here is my #realfaceofmath tweet.

Ice Screamers!

Yes, really, I have Ice Screamers in my latte!

Data and PhD Comics

Yup, sometimes PhD Comics speaks the truth.

Water Phase Diagram: Stop, Collaborate, and Listen

Clearly, I need to use XKCD's water phase diagram the next time I am teaching statistical physics.

When my students are too loud, I'll tell them to stop, collaborate, and listen.

Also notice the really great pun at the bottom. I really love that!

Beware: Protein Shakes are Dangerous

This trending Facebook headline is absurd, and it thus amuses me.

Early-Career Research Positions Available at the New Alan Turing Institute for Data Science

The UK has a new "Alan Turing Institute" for data science, and there is a call for expressions of interest from early-career researchers.

One should click on "Research Positions" in the yellow panel on the right for the instructions regarding expressions of interest.

Quoting the website (see the site for more info): Prospective applicants are invited to submit a curriculum vitae and a one-page covering note explaining how their expertise is relevant to data science and the mission of the Institute via email to info@turing.ac.uk. Full details of the application procedure will be sent in the autumn to those who register their interest.

New Dungeons & Dragons Film

I have my fingers crossed that the newly announced big-budget D & D movie will work out a bit better than the previous attempts I witnessed. (At some point, I should actually watch the animated film that was based on the first book in the Dragonlance Chronicles. I do own a copy of it, after all.) Supposedly this new film will be based in Forgotten Realms, which is a good sign. Dragonlance would have been even better.

I am cautiously optimistic. I did find some entertainment in the 2000 film, but clearly there needs to be a D & D film that is much better than that. It did have a few good moments, but it had a lot more not-so-good (or even worse) moments.

But past experience compels me to remain cautiously optimistic until further notice.

I never saw the tv show, but I have heard good things about it. Also, I have heard excellent things about The Gamers, which I really need to watch one of these years. I should also watch its sequel.

Awesome Ballpark Promotion: Free Jayson Werth Chia Pets

The Washington Nationals are giving away Jayson Werth Chia Pets at their baseball game tonight. I approve! Note: I don't know how well Chia Pets are known these days, but I remember seeing tons of commercials for them when I was a kid.

Trending Hashtag: #fieldworkfail

The hashtag #fieldworkfail has been trending lately. (However, the ones in the IFLS article aren't particularly funny.)

Because I am a theorist, it is a bit difficult for me to figure out how to contribute to it. I could perhaps discussing my escapades in my lab classes during my Caltech undergraduacy, though I would rather find something interesting from my scientific career. I'm sure I have done something as a theorist that merits this hashtag. I'll let you know if I think of something.

(Tip of the cap to Katie Mack and Jaideep Singh for their recent Facebook discussion, which alerted me to this hashtag before the new IFLS article.)

The Entropy Zoo

I am going through the draft of a chapter that includes a survey of similarity measures (and I'll need to see if an appropriate survey exists, as we should use this material to help write one if it doesn't), and the appearance of information-theoretic measures naturally made me think of the Entropy Zoo, which I saw yesterday on the Quantum Frontiers blog.

(Who's down with en-tro-py?!?)

Scholarly Journals: Screwing Over Authors for 150 Years and Counting

Hey, look: Scholarly journals were screwing authors over 150 years ago, and scholars were expressing their indignation about it.

Some traditions are alive and well...

"Structure of Triadic Relations in Multiplex Networks"

One of my papers, which my collaborators and I first posted on the arXiv and submitted to a journal two years ago, has finally been published in final form. Here are the details.

Title: Structure of Triadic Relations in Multiplex Networks

Authors: Emanuele Cozzo, Mikko Kivelä, Manlio De Domenico, Albert Solé-Ribalta, Alex Arenas, Sergio Gómez, Mason A Porter, and Yamir Moreno

Abstract: Recent advances in the study of networked systems have highlighted that our interconnected world is composed of networks that are coupled to each other through different 'layers' that each represent one of many possible subsystems or types of interactions. Nevertheless, it is traditional to aggregate multilayer networks into a single weighted network in order to take advantage of existing tools. This is admittedly convenient, but it is also extremely problematic, as important information can be lost as a result. It is therefore important to develop multilayer generalizations of network concepts. In this paper, we analyze triadic relations and generalize the idea of transitivity to multiplex networks. By focusing on triadic relations, which yield the simplest type of transitivity, we generalize the concept and computation of clustering coefficients to multiplex networks. We show how the layered structure of such networks introduces a new degree of freedom that has a fundamental effect on transitivity. We compute multiplex clustering coefficients for several real multiplex networks and illustrate why one must take great care when generalizing standard network concepts to multiplex networks. We also derive analytical expressions for our clustering coefficients for ensemble averages of networks in a family of random multiplex networks. Our analysis illustrates that social networks have a strong tendency to promote redundancy by closing triads at every layer and that they thereby have a different type of multiplex transitivity from transportation networks, which do not exhibit such a tendency. These insights are invisible if one only studies aggregated networks.
