Wow, this press release from Cornell University has made me realize that there is another meaning of the term "redshirt" besides the one that comes from Star Trek. Given the meaning that originated in Star Trek, the press release's title amused me considerably.
As I write in my latest post for the Improbable Research blog, the green-cheese origin theory of the Moon has been tested before. Well, sort of: a 1970 paper in Science includes sound-speed measurements of lunar rooks, terrestrial rocks, and terrestrial cheeses.

Yesterday, the new Baseball Hall of Famers (Craig Biggio, John Smoltz, Randy Johnson, and Pedro Martínez) gave their acceptance speeches. Pedro Martínez stole the show and(unsurprisingly) was particularly charismatic, although he did take a brief shot against the Dodgers. You can watch all of the induction speeches on this website. I love the pictures of the four new Hall of Famers side-by-side, because Randy Johnson is just about a head or more taller than the other three guys. The MLB.com Facebook page posted a picture from this weekend with Pedro Martínez and Tommy Lasorda together. Martínez is smiling broadly, and Lasorda has a look on his face that seems to say, "I can't believe we traded Martínez for Delino DeShields!" (I tried to find that picture on a public page, but I wasn't able to find it with a search on Google Images.)
According to a new study in the journal Organizational Behavior and Human Decision Processes, it may well be. The study, called "The highest form of intelligence: Sarcasm increases creativity for both expressers and recipients", was published by Li Huang, Francesca Gino, and Adam Galinksy. As with all other recent papers in journals by world-renowned publisher Elsevier, the study has five self-reported highlights: (1) Sarcasm is an instigator of conflict but also a catalyst for creativity. (2) General forms of sarcasm promote creativity through abstract thinking for both expressers and recipients. (3) Expressing sarcasm to or receiving sarcasm from trusted others increases creativity without elevating conflict. (4) We manipulated sarcasm via a simulated conversation task and a recall task. (5) We employed three different creativity measures and a well-established measure of abstract thinking. I feel like this study has justified the last 39 years of my existence. Note: Absolutely no sarcasm was employed in the writing of this blog entry. (Tip of the cap to Taha Yasseri.) Update: A modified version of this post is now on the Improbable Research blog. Update: Hmmm... I have pondered a bit, and I am now wondering if there are Elsevier journals --- such as ones that publish review articles? --- in which the five self-reported highlights are not required? It is possible that it should technically be "most other" or "almost all other" rather than "all other". I will leave an exhaustive check, or a search for a counterexample, as an exercise for the diligent reader. (My best guess is that it is policy for all research article, but I am not sure if it is also true for review articles, so "all research articles" is another potentially viable tweak to the phrasing.) Update: Here is a blurb about the research in The Harvard Gazette. (I found this link via Francesca Gino's Twitter account.)

Yup, that's right: a Commodore Amiga has controlled the air conditioning in a Michigan school district since it was installed in the 1980s. That's pretty spectacular (and also "awesome"). (Tip of the cap to Myah Evers.)

On extremely rare occasions, I see a movie (or read a book or play a game...) that shows me a new perspective on things and fuels my imagination (and my Abstract Thought). Pixar's Inside Out is one of those movies. Wow, just wow. I had heard excellent things about Inside Out and was really looking forward to it after watching a trailer after seeing a colleague gush about the movie on Facebook, and I have to say that I am amazed. I wouldn't say that movies amaze me very often, but this one did. I'll have to think about whether it has surpassed The Incredibles as my favorite Pixar movie of all time --- I haven't decided yet, but it's possible --- and "best Pixar film ever" is very high praise indeed. (The short film before the main feature could have been much better, however.) Anyway, if you haven't seen Inside Out yet, I suggest that you go see it. Perhaps even stop what you're doing and go see it? It's that good. And now, as usual, it's time for me to spend some more time in Abstract Thought and Imagination Land (two of my favorite places). :)

That's quite a layout fail, CNN.com. One of the things we learn about in journalism concerns the relative placement of different articles---including if one headline might be confused as the tagline for the other. CNN.com, I think that one of your employees probably needs to brush up on this lesson.
I don't remember ever hearing about the young lioness that got to hear a freshman physics lecture at Caltech, although it's possible that I simply forgot about this story (with picture proof from a very familiar lecture hall). Wow!
Some of the fake customer service trolling on Facebook is really funny. I especially like the answer in the Starbucks complaint. (Tip of the cap to Iain Macmillan.)

Our Nature Communications paper just came out today! Here are the details. Title: Topological Data Analysis of Contagion Maps for Examining Spreading Processes on Networks Authors: Dane Taylor, Florian Klimm, Heather A. Harrington, Miroslav Kramár, Konstantin Mischaikow, Mason A. Porter, and Peter J. Mucha Abstract: Social and biological contagions are influenced by the spatial embeddedness of networks. Historically, many epidemics spread as a wave across part of the Earth’s surface; however, in modern contagions long-range edges––for example, due to airline transportation or communication media––allow clusters of a contagion to appear in distant locations. Here we study the spread of contagions on networks through a methodology grounded in topological data analysis and nonlinear dimension reduction. We construct 'contagion maps' that use multiple contagions on a network to map the nodes as a point cloud. By analysing the topology, geometry and dimensionality of manifold structure in such point clouds, we reveal insights to aid in the modelling, forecast and control of spreading processes. Our approach highlights contagion maps also as a viable tool for inferring low-dimensional structure in networks. Instead of trying to explain our work in layperson's terms here, I'll point you to the press release from University of Oxford. You can also download our data and our code.

About three weeks ago, I wrote an answer to the question "What is the Most Exciting New Research in Mathematics?" on Quora. Take a look at what I wrote, and pipe in with your own thoughts.

These overly honest slogans for university majors are bloody awesome! It's tough to pick a favorite, but right now I think the one for communications is perhaps the funniest. We'll have to make our own for mathematics, which didn't make the cut for this article. I know I've seen a bunch of these before, so I also wonder if I have seen (or even posted on my blog?) this exact list before? (Tip of the cap to George Takei.)
Today I am flying to Dresden, Germany for the MAPCOM15 workshop (on the Mathematics and Physics of Multilayer Complex Networks) that I am co-organizing with Alex Arenas. A certain highly coveted Karate Trophy will also be there, so let's see if it will be passed along to the next recipient.

Yes, that's right. Using a new tool called "SMUG: Scientific Music Generator", one can now generate music and lyrics from academic papers. I love the acronym. :) I also decided to try SMUG. I generated this work of art from my review article on multilayer networks. Update: The paper's bibliography includes a citation of The Legend of Zelda: Ocarina of Time. I am amused. :)
