Quote of the Day

I just finished reading an article by Gerald Folland about communication between mathematicians and others, and he mentioned (and hence reminded me of) the following wonderful quote:

Mathematicians are like Frenchmen: whatever you say to them they translate into their own language, and forthwith it is something entirely different. (Johann Wolfgang von Goethe)

My Power Animal = Angora Rabbit

Apparently, my power animal is the angora rabbit.

Naturally, all this talk about power animals makes me want to quote Keanu Reeves (lines 1 and 3):

"Call your power animal."

"Come here."

"Do it in your head."

The Physics of Shaking Oneself Dry

The videos discussed in this blog entry are awesome. I am guessing (1) that this is one of the videos for the 2010 Gallery of Fluid Motion and (2) that it will also end up being one of the winners.

Best. Slogan. Ever.

A "sport" called Major League Dreidel has the best slogan ever: "No Gelt, No Glory!"

I approve!

Congratulations to Dr. Dan Fenn!

Dan Fenn, my first Ph.D. student, passed his thesis defense today with flying colors. (He has on the order of 2 hours worth of corrections that he needs to make.) His thesis concentrates mostly on topics in mathematical finance, with a focus on financial networks. He also developed some new theory related to community detection in networks.

You can find some of Dan's work in our coauthored papers that I've posted on my website (and 2 more of them will be posted very soon). Once all of the i's have been dotted and the t's have been crossed, I will post his dissertation per se.

CONGRATULATIONS, Dr. Fenn!

Unpopular Science

This particular cartoon guide to physics is fantastic! It appeared a couple of days ago in the New York Times.

RIP Paul the Octopus (2008-2010)

Paul the Octopus, the cephalopod who took the world by storm with his oracle-like soccer predictions, has died. RIP Paul.

Citation Errors as Genetic Mutations

As this opinion piece discusses, citation errors are rather analogous to genetic mutations.

Unfortunately, the optimism expressed at the end of the article that referencing software will help matters is misplaced---my experience is that such things induce new errors rather severely.

Words of Wisdom from Bill James

"To use academic jargon is rude, lazy, elitist, and counter-productive. It diminishes the influence of the academic world; it diminishes the influence of thinking people on the general debate. If you want people to accept your ideas, you have to speak in language that others can understand. This is common sense, and it is common courtesy."

Amen.

(Of course, one needs to be precise in journal articles, but that doesn't mean that certain things can't be made understandable or that we can't speak and write things in other venues to help facilitate understanding. Anyway, the point is: Know thy audience!)

Moustache of the Day

Now that is a serious 'stache.

Congratulations to Dr. Felicia Gottmann!

On a few occasions, I like to highlight accomplishments from my friends in this spot. (And we all know that I spend too much time talking about myself anyway, so this is a welcome break from the usual deal.)

I just got back from the celebration for a successful D.Phil defense (a "viva") for one of my best friends---for one of the dearest, closest friends I have ever had or will ever have. And I try to do the best I can in return.

So that means it's time to pause and use this spot to express congratulations! Felicia passed with flying colors, which was not a surprise at all. (A foregone conclusion in fact, though it's obviously always better after the fact.)

I know Felicia through Somerville, and she studies French and history. The title of her thesis is "The eighteenth-century luxury debate: the case of Voltaire"---quite far from anything I can even pretend to know, but surely that is because all is for the best in this best of all possible worlds?

There were a lot of mathematicians at the pub, so ironically I was the one who knew other people. This resulted in our table getting recruited for charitable donations (one of the staff members left her job today and was celebrating the end of her job), and one of my students also dropped by to say 'hi'.

Anyway, it was all very excellent and fun, and now I am pretty tired. I should also mention that Felicia's mother (who flew in from Germany for the celebration) called me "an international phenomenon". Maybe I should adopt that as my tagline?

It's not every day that I get to celebrate an important day for one of my best friends, so today has been a good day.

CONGRATULATIONS, Dr. Gottmann.

"Dance Your PhD" Contest 2010

There is apparently something called a "Dance Your PhD" contest, and here are the entries for 2010.

I didn't know until just now that this exists, and I have to say that I am afraid to watch some of these videos. My dissertation was called "Quantum Chaos in Vibrating Billiard Systems", and I think that the presence of the word "vibrating" would have made this a clear winner in 2002.

A Techer's New Adventure

Tomorrow, fellow Lloydie Rachel Gray '00 goes to Italy to start her new life as a nun. Pretty soon it looks like none of us will hear from her for a long time (she won't have internet access, and apparently she can't write or read snail mail except from close family). You can read about her life decision on her blog (which I suppose won't be updated for quite a while...), so for those of you who know her, now is definitely the time to send her well wishes. Hopefully our paths will eventually cross again.

Best. Law Firm. Name+Slogan. Ever.

I have only two words to say: I approve!.

New to the Blogroll: "Principal's Blog", "Somerville Historian", and "Complex Matters"

I have added links to new blogs maintained by three of my Somerville colleagues: our new Principal, one of our history Fellows, and one of our physics Fellows.

Isn't it just like me to show my support?

Does Judaism Get Wile E. Coyote?

Here is the straight line (you provide the joke): The Vatican has apparently declared that Homer Simpson is Catholic.

Meanwhile, back on Earth...

Tales from the ArXiv: Tibetan Singing Bowl

A new paper on the arXiv discusses the Tibetan singing bowl. We have one of these in OCIAM, though note that this one isn't like those depicted in the wikipedia article.

Here is more information on the new article on the arXiv:


Title: The Tibetan Singing Bowl

Authors: Denis Terwagne, John W. M. Bush (the fact that John Bush is involved is not a surprise at all!)

Abstract: The Tibetan singing bowl is a type of standing bell. Originating from Himalayan fire cults as early as the 5th century BC, they have since been used in religious ceremonies, for shamanic journeying, exorcism, meditation and shakra adjustment. A singing bowl is played by striking or rubbing its rim with a wooden or leather-wrapped mallet. The sides and rim of the bowl then vibrate to produce a rich sound. When the bowl is filled with water, this excitation can cause crispation of the water surface that can be followed by more complicated surface wave patterns and ultimately the creation of droplets. We here demonstrate the means by which the Tibetan singing bowl can levitate droplets. This is a sample arXiv article illustrating the use of fluid dynamics videos.

What happens in Limerick stays in Limerick

I am taking my second trip to Ireland. I will once again be flying into Shannon and heading down to Limerick to give a seminar and collaborate (and occasionally to stop and listen). However, I probably won't present my conclusions in Limerick form on this occasion---because it went over so well last time...

I have a bit of a backlog of established invites in various countries that I will eventually do: Spain (again), Portugal, Singapore, China (again), France, and Germany (the last for social purposes, though I technically also have an academic invitation that may or may not have expired) come to mind. At this point, I doubt that any of them will happen in 2010, but hopefully I'll do some of these in 2011. There is also a conference in Hungary (in Budapest) in June 2011 that I would like to attend. Lots to look forward to!

Busted

This demotivational poster is a big win. Actually, it's not truly the poster that's a win but rather the TA for the class in question. Nice job!

RIP Benoît Mandelbrot (1924-2010)

I can't yet find an article to confirm this (though it's mentioned on a couple of blogs and private websites), but it appears that the mathematician Benoît Mandelbrot (as in the Mandelbrot set, among other things) died on Thursday.

2010 has been a really bad year for dynamical systems (and allied subjects---fractals and related phenomena, in this case). We've lost so many big names this year.

Update: The New York Times has now posted a proper obituary. Also see the blurb in Wired.
