Econlinks: The applied maths edition

• Serious fight on evolutionary theory ground. The bulk of evolutionary theorists seem to be set on taking Nowak et al to the guillotine, but there is also a small minority of fans: among them, my former Tinbergen Institute colleague Matthijs van Veelen (see a picture of him from when he was older, wiser, sporting a big white beard; NB: yours truly is the junior black-and-yellow fellow at his left, learning on the job) and his co-authors have a nice correspondence in Nature supporting Novak et al. PS. Note also that one co-author of the controversial paper is Romanian mathematician Corina Tarnita (whom, allegedly, many girls would/should like to have as role model)
• The wave equation and tsunami propagation: a concise exposition by Terry Tao. Brings back nice memories of my maths classes at Utrecht University.
• Life arithmetic with (unavoidable?) implications: "Life is short. Have an affair".
• New chess strategies (more)? Now to the good guys: the latest (and seemingly, last) Amber chess tournament was clearly won by Aronian-- followed in the combined rankings by Carlsen and Anand: these three are in my view also the only consistent, long-run runners in the chess marathon. And related: Carlsen's bold decision to challenge a by-now-obsolete chess world championship format.  
• Greg Mankiw with the correct (and scary) budget arithmetic. 
• This is piece of cake, walk in the park: should have focused on predicting Burgundy 2011 vintage quality :-). But agreed, it was better than mine.
• A trip through a Mandelbox. Via Alex Tabarrok at MR.
• The science of stout foam. Or: the time of cheaper Guinness is nye! I confessed already that I had chosen a great Condrieu (relative to the other wines I had at Alinea, this was the one unforgettable) on St. Patrick's, but obviously I still fancy the good old Irish stout! 
• On continuous harmonic spaces (the original paper). Shows that consonance and dissonance  in music are to a considerable extent routed in nature and can be described/defined mathematically, beyond cultural or time relativism. We like it!

On multicore Stata MP performance

Since I am in the middle of some very interesting discussions and experiments concerning this topic: it really does look like the difference in speed between the different multi-core/multi-processor Stata/MP versions is considerable. Right now I am performing a comparison exercise* with my friend and co-author Miguel, where, it turns out, a number of certain estimations with a 8-core Stata/MP 11 take about 10 almost 15 times less real time (I know, I hardly believe it myself) than (almost) the same estimations done with a 2-core Stata/MP 11. Taking the median across all estimations commands in Stata, an 8-core will outperform a 2-core by a factor of 2.28 (NB: this ratio appears to be larger than the price ratio of these two multicore versions!): I computed this figure from other stats available in this 250 pages report on Stata MP's performance.

The next quest should be to assess Stata's bold claim: "From dual-core laptops to the big iron of multiprocessor servers, Stata gets the most out of multicore systems. No other statistical software comes close" (my emphasis in bold). If true, that surely ought to boost Stata's status in the statistics/econometrics community (part of which-- I plead guilty too-- is currently infatuated with using other programming languages like Ox, Fortran, Gauss, Matlab etc, while typically leaving Stata for simple exercises or data manipulation).


*brief update footnote here, for clarification (well, at least part of the clarification..., the huge, factor 10 15, execution time differential remains somewhat puzzling): we cannot really perform this comparative exercise directly, as "(almost) the same" here means  that we do have  identical specifications (and the same software and operating system), but nonetheless different  (very large) panel datasets-- and in this particular case the difference in the structure (specifically, the "connectedness" of the cross-sectional-time series data, but the intention was not to give too many details) of those datasets matters, beyond an eventual difference in  the number of observations (for our purpose virtually the same); if we ran identical specifications on exactly the same dataset, with the 8-core and respectively the dual-core Stata/MP, the speed ratio could not be higher than 8/2=4, the theoretical limit. Given the type of exercise performed here, the real time differential due solely to the difference in core numbers is most likely close to this limit.

What I have been reading

A couple of books I have read within the past few weeks, most of them on my Kindle 3G device(*):

Scott Berkun's "Confessions of a Public Speaker" (get the Kindle edition): the author is a professional speaker, in front of audiences large and small, hence he has got some very helpful tips for anyone who ever needs to engage in public speaking, mostly drawn from his own experiences. These tips range from the a priori preparation for your speech, to engaging your audience, to knowing what to do when you have a too large room and too few people in there etc.What is missing, but understandably so given the author's career, is the treatment of academic public lectures, which can be quite different than any other public types of speech-- nevertheless a series of Berkun's recommendations work perfectly also for academics. The book is at the same time a very fun reading.

***

Jason Zweig's "The Little Book of Safe Money: How to Conquer Killer Markets, Con Artists, and Yourself" (get the Kindle edition): useful advice for small investors (that can be probably summed up by the following quotes "for most small investors, an indexed bond mutual fond is the best way to go" and "[d]on't invest in leveraged and inverse ETFs. Leave them to professional traders" ...) and adapted particularly for the US audience (you do find for instance very helpful info on the so-called '529 plans,' including some online links to compare various such plans, in case you are interested in that). Definitely not for more sophisticated investors (some of you, readers of this blog) or for people who've read much more detailed stuff on financial investments earlier (although I am myself in this category, sometimes it is useful to consult other perspectives at a more elementary level). A tad too cautious and limited on scope and purpose. Anyhow, if you are a beginner and (plan to) live in the US, by all means do read this book.

***

Steven Levitt and Stephen Dubner's "Superfreakonomics" (get the Kindle edition). I find this better written than their first Freakonomics success (see, e.g., the first bullet point here for some of the huge debate on that earlier book)-- probably experience and learning on the job-- though it contains as little economics as the first one (it is written more in an investigative journalism style: Dubner obviously has the feeling for what sells and what not). That being said, I still think it is eventually a great service even to the economics  academic community (at least in drawing attention to the range of situations/phenomena that economics can be applied to; NB: I personally doubt it would give the/a too wrong impression of what economists do and should do-- if anything, it might convey the idea that some economists know very well how to sell their books,), and probably that writing it in more 'econo-prose' would have reduced its popularity. I would particularly recommend it to any non-economists, for sure (e.g. last winter I noticed the Romanian translation of the book is already out, and made it present to a good old Transylvanian friend of mine-- in function of his reaction I might offer it to my parents as well). By the way, related, the Freakonomics documentary is currently available for instant viewing on Netflix (I correct myself: right now their site is down, but it is the first time I do not see it functioning), if you are in US and have access to that service-- I plan to watch it one of the next days.

And now to my two favorites in this set: 

John Adams's "Hallelujah Junction. Composing an American Life" (unfortunately not available on Kindle): this is one of the best autobiographies I have ever read, within the musical realm and beyond. Honest, full of wit, style, and extremely informative-- and that to say the least. As somebody who's listened to a large set of Adams's compositions (and working on the remaining ones...) and who regularly follows his blog, I simply had to read his autobiographical piece in order to have access to Adams's detailed perspective on both his  own work and his general ideas of music (composition, interpretation, intrigues, all the hoopla), politics, life, everything... Highly recommended: one of those books that you simply cannot stop reading once you have started. I'll most likely refer to passages or ideas from "Hallelujah Junction" in many of my future blogposts.

Steven Landsburg's "The Big Questions" (get it on Kindle): I will only tell you that this book is from my perspective really scary, in that its author appears to think about  crucial stuff --i.e. mathematics, economics, physics, philosophy, tax policies, trade, sex, religion, life, Universe etc.-- in an almost identical way to yours truly (ok: I should maybe phrase it as "I think almost exactly like him"-- after all he was there before me...). In any case, even if you've known all the time and agreed all the way with everything in the book (though he does cover an enormous range of topics, requiring that you'd be an extremely well read person), Landsburg's exposition is one of the clearest I've ever encountered (this is true also for his previous books, some of them recommended earlier on this blog; I will only say here that I even used an earlier quote from him as one of the "propositions" --"stellingen", in Dutch-- to go along with my PhD thesis defence-- see under IX in this list). In particular, he's got the rare ability to explain in few paragraphs, mainly by means of easy examples and analogies, some highly complex material (try explaining quantum physics or deontological vs. consequential ethics to the non-initiated!), albeit he needs to strip them down to the bare essence (but then again this is a popularizing book, aimed for a wide audience). Landsburg's writing style is also something I personally like a lot: he's got just the right amounts of humor, irony, and even the tiny bit of arrogance (why not?) mixed in his book. Check out also Landsburg's "The Big Questions" blog, something I've followed and enjoyed since its very start. I end with a larger quote from the introductory chapter of "The Big Questions" that is likely to give you a good feeling of Landsburg's 'creed' and goal in this book (as well as the similarity with my own academic training and beliefs, c.f. the scary/eerie part from above):

"[...] I went on to a career of research in teaching in both mathematics and economics, with a little dabbling in physics along the way, but I never lost sight of my fascination with the big questions of philosophy: Where did the Universe come from? Why is there something instead of nothing? How is knowledge possible? What justifies a belief? How can we tell right from wrong, and good from evil? How should we live our lives?

Philosophers have useful ways of thinking about these questions, but so do people  who are not philosophers. Physicists know something about the origins of the Universe; mathematicians know something about the patterns of reality; economists know something about how our choices affect the lives of others, which is not distinct from the problem of distinguishing right from wrong. I've come to believe that these disciplines provide some of the best available tools for chipping away at the problems of philosophy.

When a man  with a hammer tells you that everything looks like a nail, you should doubt his objectivity. When a man who knows some math and economics tells you that the problems of philosophy can be solved with math and economics, you're entitled to exactly the same reaction. But in this case I believe the causality runs the other way: I was drawn to math and economics because they illuminate the big questions. I saw the nails and went out to find a hammer. [...]"

(*)which is absolutely fantastic and you must have it, despite 1. the fact that David Letterman cannot find page numbers on the Kindle books -- and hates it because of that; 2. the fact that each Kindle book costs more if you buy it outside US-- function of the IP address from where you log in to your Amazon account when buying it (before investigating and realizing this, I did actually buy quite a few Kindle books during my European winter holidays-- and ended up paying about 50 bucks more than I would have paid, had I bought them here in the US). In any case, I am the owner of more than 100 Kindle books already (yes, Amazon, I expect some loyalty awards!): given my fairly long commuting time between Lakeview, where I live, and Northwestern Univ in Evanston, I can read up to two or three books in good weeks.

Econlinks: Of (visual) art, old and new

• The third and the seventh: imagination materialized or Alex Roman's computer generated art. Via Michael Nielsen. 
• Staying in CG: meet Julia Map, of Google ancestry. And since we're here, read how the fractals changed the world --which was in a way also part of the obituary to Father Fractal, Benoit Mandelbrot, who passed away a couple of months ago; see a better one from the Economist. My own brief memories of him: I met Mandelbrot at a workshop on economics with heterogenous agents (WEHIA) at Essex University, back in 2005. Before his keynote speech, he introduced himself in the following very humorous way (paraphrasing): "Hi, I am Benoit Mandelbrot. And I am not dead yet. [pause] I tell you that because I have just met somebody in the corridor who told me: 'OMG, you are Benoit Mandelbrot. I thought you were dead for a long time now' ". 
• Meet Jeremy Mayer, tamer of the typewriter. "I disassemble typewriters and then reassemble them into full-scale, anatomically correct human figures. I do not solder, weld, or glue these assemblages together- the process is entirely cold assembly. I do not introduce any part to the assemblage that did not come from a typewriter". 
• Back to the traditional, but impressively executed: meet Camille Seaman. From the "Last Iceberg series" statement: "Nick Cave once sang, 'All things move toward their end.' Icebergs give the impression of doing just that, in their individual way much as humans do; they have been created of unique conditions and shaped by their environments to live a brief life in a manner solely their own. Some go the distance traveling for many years slowly being eroded by time and the elements; others get snagged on the rocks and are whittled away by persistent currents. Still others dramatically collapse in fits of passion and fury."

Econlinks: In degrees of awesomeness

• Greg Mankiw seems to be arguing for a European-type separate master + PhD graduate Econ program-- such as those at LSE, Oxford, Pompeu Fabra, Tinbergen Institute, and (I guess) the newish Paris School of Economics entity-- rather than the US-type graduate PhD package, which comes with a (usually elective) master on the way (that is somewhat ironic, given the desire of the typical high-aspiring European place to ultimately emulate the US top places). In any case, assessing the total costs and benefits of these two alternatives remains a difficult empirical quest.
• Awesome grants, via Michael Nielsen.
• MR has linked to direct evidence that the History academic job market was hit way harder (e.g., this year lowest number of positions in a quarter century) than the Economics academic job market (and most likely than any other discipline's job market), which is almost back to the pre-recession level. (My wise friend Daniel, the historian of science with whom I talked several times about this, was absolutely right in his intuitive assessment) 
• Awesome (albeit late) discovery. After reading Gelman's WSJ story, I am decided to request a priori a "kill fee provision", whenever I am asked again to write stuff for various non-scientific outlets; I had similar experiences with a couple of Romanian (some, not surprisingly, now defunct...) newspapers, and, in particular, with the (very surprisingly, still surviving...) Aarhus School of Business internal press. Except that I ended up wasting time and not getting any 'kill fee' for it. Sometimes you have to learn from your own mistakes.
• Creative love song for Friedrich Hayek. Great, as so far Keynes seemed to get all the love (plus the hangovers, true): last bullet point. 
• Very well presented classic economic arguments for raising public college tuition fees by Gary Becker and Richard Posner. Digest them carefully, as they might appear counter-intuitive (witness the frequent nonsensical arguments against such tuition raises) even to intellectuals -- those without training in and/or understanding of Economics. 
• Awesome reply to comment in the scientific journal world. 
• As controversial as outputs of such activity might currently be, concretely gathering brains in such 'intellectual ventures'--in fact: literally leading to brainstorming-- is just awesome. The idea in itself is of course not new, Myhrvold just had the will-- and financial means!-- to implement it on such a scale

• Good, Gelman is even more pissed off with Greenspun's to-a-large-extent-nonsense than I was: 9th bullet point.

• The culture of Old Europe (aka, new European Union...), via Gabi Istrate; I've also promised him I would carefully look at/comment on this: the promise is still there, the time-- not yet... :-).

• I am very curious how big this can/will get. After all, a whole Nobel might be at stake (I confess: I never really liked Gore, on any dimension; I still think he is submediocre or worse; however, I thought/still think that some of the climate guys/gals who won within the IPCC were more than decent...). This is not so much about scepticism (of any kind/degree), but first and foremost about scientific honesty. Seemingly a very rare quality today.

• I guess I am not in such of an intimate relationship with Tokyo after all (despite this...), since I didn't manage to meet any of the city's "groundbreakers" (though ok, fine, between me and you only: the truth is that I've been playing hard to get with Tao Okamoto)

Tokyo, Narisawa, Takemitsu: Arigato!

It happened almost two months ago (see last bullet point here), so I've thought it is about time I gave you some impressions about my Tokyo trip :-). Obviously I do not plan to get into what you can find described in detail online, e.g. the more than decent Tokyo-wiki source.

For starters, very briefly, some (incomplete, random, and likely very personal) general impressions about Tokyo. My good old friends Sae and Folkert gave me plenty of information and advice on what I must see, but unfortunately I did not eventually manage even half of that... For instance, places outside Tokyo, like Yokohama and Kamakura, are priorities for next time (though Kyoto is clearly my number 1 priority in what regards my next trip to Japan, will try to make that happen as soon as possible). I also had very little time, however, for Harujuku (but, just from what I did see, I have to say that I like Ginza as shopping area, and also simply as city area, much more) and I only saw Roppongi by evening/night time (restaurants in the area are lovely; the persistence of the many black American guys trying to get you in every (strip)club is quite annoying). Loved the Tsukiji fish market (though I arrived there pretty much after the main action was gone; I am not a morning person...), particularly eating very fresh sushi right in the middle of it (after queing ad infinitum: I guess I am not the only sushi lover). Very very unfortunately, I did not have enough time to look for and try this place called Daiwa sushi, allegedly the best sushi place in the world (see the third bullet point from here for that Guardian list), very close to the Tsukiji market as well. In any case, once you eat sushi and sashimi even in average places in Tokyo, you will never ever want to eat them outside Japan-- there is simply no comparison! To the other Japanese delicatesse: the "Kobe beef temple" in the middle of the electronic town (Akihabara) was fantastic; I could have basically eaten all that beef raw.

People in Tokyo are very stylish, in general. The style and very good taste are actually extending beyond personalia and are to be found everywhere; for instance, quite impressive is that the most unassuming, average restaurant/ cafe, will play Norah Jones, or Gershwin, or Mozart, or Takemitsu (of whom more below). I was negatively impressed however by how few Japanese speak English, and how bad they speak it when they speak it (just try to ask for directions to random people in the street...you will not try a second time). They are also obsessively polite (which, very likely, you know already: what I am telling you is that they are even more polite than whatever you heard/imagined). The center is extremely crowded, at every hour (Amsterdam is Mickey Mouse compared to Tokyo, in that regard); I am still puzzled by the (seemingly stable...) equilibrium consisting of pedestrians and bicycles in full speed, sharing the very same sidewalk. Too humid and warm for my October mood, but I guess one can get used to it. The Japanese toilets are just the finest piece of technology ever put to basic needs use: I am actually very surprised that they did not get popular outside Japan; in Japan they are (still) en vogue (the very funny conference guide we had explained us that Japanese people might not want a dishwasher, but then every single one of them will have the latest technology toilet). The guided bus trip around Tokyo after the CAED conference, with a long stop at the legendary Senjoji temple in Asakusa, and particularly the great dinner & cruise on the Tokyo Bay (under a beautiful starry night) that finalized it all, were by far the best sightseeing part, from my perspective. Needless to say, the dinner ended-- as usually in Japan, I am being told-- with a very succesful karaoke (no, I did not participate in the singing part; you really wouldn't want me to participate) where, inter alia, I learnt that David Neumark has another competitive advantage next to that of the economist: he is the best interpreter of Deep Purple songs after Deep Purple themselves :-).

One of the absolute highlights was the lunch at Les Créations de Narisawa (many thanks to Valérie for the extremely inspired suggestion), a superb 1-star Michelin restaurant and the best restaurant of Asia (number 20 in the world) in 2009, according to San Pellegrino (this is by no means little accomplishment, particularly given the sea of Michelin-starred restaurants in Tokyo alone! Actually, I conjecture that Narisawa's restaurant will receive the 3 Michelin stars in 5-6 years, the latest). There are simply no words to describe my impression about the food, so I will let Valérie's pictures speak instead (I am too lazy to put mine online for now, but this will happen... at some point-- I might then link back to this blogpost): the menu, first appetizer, second appetizer , third appetizer, first starter, second starter, main dish, dessert plate, dessert 1, dessert 2, dessert 3, Japanese white whine (instead, I tasted a fabulous Chateau Lestrille, Entre-deux-Mers, 2008: it is the first wine described here), I also had the best mint green tea in the world; unfortunately you will have to imagine the taste from looking at the pictures, at least until you manage to get there...). The service was beyond perfection. And, to top it all, no less than the famous chef, Yoshihiro Narisawa himself, came at the end of the lunch to greet and have an informal chat with us: now this is what I call caring for your customers; I solemnly declare myself the biggest fan of Narisawa-san! In a nutshell, this was by far the best lunch I've ever had.

I'll end with a few lines on one of my alltime favourite-things Japan, i.e. my favourite Japanese music composer, Toru Takemitsu. Unfortunately, although I planned it carefully before getting there, it turned out I could not save enough time to go and look in Tokyo for a bunch of Takemitsu works that I definitely definitely must have. So I'll probably end up buying them from Amazon instead. Anyway, here's just a flavour (with thanks to YouTube... and hoping they would not be removed from there any time soon) of some of my favourite Takemitsu pieces. Just ideal for starting the week, my very number 1 Takemitsu work, a 200% masterpiece: November Steps (Part 1; Part 2). And if you have even more time (you must!), listen also to my preferred Takemitsu soundtrack, Black Rain, and to one of the finest piano works out there, Rain Tree Sketch (which I actually heard being played in Tokyo, in one of the nice cafes from Ginza). Enjoy!

Weekend econlinks

• Sharing information in scientific research: yes/no/when. Interesting, but the analysis here is applicable only in the context of some sciences (arguably, not most). Moreover, sharing by means of co-authorship is discussed at best indirectly (if one is willing to expand on their repeated interaction game thread...). But my major "disagreement" has to do with their upshot: my conjecture is that know-how sharing is, ceteris paribus, over all disciplines, U-shaped in the degree of competition (and, since I also believe that, overall, very high competition dominates very low competition equilibria, you already know what my prior of the ideal is). Remains however an open empirical question for now.

• We are what we ate: Tony Judt's culinary autobiography. Reminds me that (fortunately) I have only got to know top Indian restaurants in London (in general, Londonese Indian cuisine is probably, up to now, my favourite in the world; though surely there is a variance): a lot must have changed.

• Stanford also jumped in Google's bandwagon of online (dissertation) publishing.

• David Brooks on "the other education": concise and well written. I usually call this second education "exposure". The vast majority of people I've met hardly had any.

• Hyperopia... as a concern.

• Cheaptalk on the election process of Econometric Society Fellows. Not extremely surprising or, for that matter, singular within Economics; after all, they almost forgot Hurwicz for the Nobel Prize..., for largely the same reason: most of the people who used to propose and lobby for him died at some point... I think Ely is right: focus on the young people-- at least that would be an attempt to solve the problem for the future... And yes, for potential candidates why wouldn't you just look to the Econometrica editions (Lones Smith's suggestion in the comments)...

• Music critic review: mode d'emploi, by John Adams.

• Sex toy research. Or Ariely in the quest for another Nobel Ig :-). Goes without saying that I am extremely interested in the results.

• Philip Greenspun on universities and economic growth; via Razvan, on Ad Astra. First impression: he writes much and he misunderstands a lot; particularly the Economics of it all (no, he is not qualified to understand what is clear and what is controversial in Clark's book, to give but one example). Also, doesn't seem to realize (not sure whether qualifying this as voluntary misrepresentation would be better or worse...) the difference between statistical and anectodal evidence. And, in general, he doesn't seem to have decided whether his target is to make people incensed at or interested in what he has to say. BUT, although he errs nearly everywhere else, I agree that a. much change is needed in the way teaching in most universities is done nowadays (see also the 3rd bullet point here on opinions on the value of college education & all that jazz); b. he has some very decent ideas there (others had/have them too) and c. these changes would not cost too much, with the benefit very likely to outweigh that cost. (Probably) Inadvertently, Greenspun is actually arguing for a "Japanese approach" (which the Japanese apply to both teaching and on-the-job training): give a rather broad ("customer-based", if you want some context) training, be able to/ focus on study/work in teams, always help the new/junior ones etc. etc. There is however a known problem with the (standard) Japanese perspective to (life-long) education that I am not sure Greenspun is aware of... Simply put, you really do not want to give no/wrong incentives at the very top of the ability distribution.

• One of the two prediction markets on the 2009 Romanian Presidential Election is now closed and cashed-out (the other one is also "closed", but waiting for the final results on Dec 6th), as the official First Round results of that election are out. Several participants won (virtual) money (yours truly included), but the congratulations go to Dan, as he is the one who won the most (a fortune!). Which means that he is obviously going to pay for the (very good: e.g. the French on this list?) wine, with the occasion of our next meeting :-).

Top Gear in Romania. Or: keep up with the Sandero!

If you're not going to die of laughter before that, you will when the Dacia Sandero appears (and overtakes them) :-). Oh, and this gem from Clarkson is to save for further reference: "If Simon Cowell came here [Mamaia, Romania], they'd put him on income support". Brilliant!

Thanks to George for the tip!

Chess games, more and less serious

First, the powerful Corus Chess tournament has started today (first game tomorrow) in Wijk aan Zee. Time for last year's Group A winner, Magnus Carlsen, to really make history. Ivanchuk did quite well lately, but I still don't see him with too many chances against the Viking Chessmaster, this time. Aronian is, however, always 'unpredictable': hence, if anything, he's the one Magnus should watch out for the most... Group B will also be very interesting: my bet is on the new hope, Fabiano Caruana: I saw some unbelievably smart games he played in different tournaments last year.

Second, computer chess games for the less professional players, such as myself :-). In order to have an idea whether I should get the new chess program for my Ipod (see also here), I should ask Susan Polgar how does the tChess compare to the Kasparov Chessmate , the latter available within the set of games offered on the screens in KLM intercontinental flights (now you know that other than watching good movies--2nd bullet point-- I also play a lot of chess on such flights...). I am obviously no pro when it comes to chess, but I won 15 games (and lost only 3) against the highest level the Kasparov Chessgame has ('strength' 2300, ie. playing against Kasparov's avatar...), which clearly says more about that game than about myself :-). If the Ipod chessgame is similar or lower in strength, I wouldn't bother (though in any case, I think it is absolutely great to have such a chess game on Ipods and Iphones)... All in all, I am definitely looking forward for Fritz-like strength in chess games on such devices as Ipods, KLM screens and the like...

Rubik's solved in max 25 moves

...from any initial configuration, that is.

The above was on theory and impressive computing power. See also a former post of mine on the latest Rubik's cube pratical world championship, with winning results here. To retain: the least number of moves to solve the standard Rubik was 35; in the speed competition the standard Rubik was solved in 11'50''. Don't start crying now :-).

Chinese (Couch) Potato

"Tudou.com" (="Potato", in Romanized Chinese) is one of the several Chinese "Youtubes", seemingly the largest one at present (possibly larger than YouTube itself in some dimensions). Tudou's stated goal is "to move couch potatoes from the TV screen to computer screens, a process very much under way in China". Here's their wiki entry. While this might be not very exciting yet, what might knock you out is the fact that you can watch on Tudou an amazing number of excellent (whole) movies, both recent and old, in very high definition media format (typically split in several parts). For instance, you can find entirely the top 5 movies (and probably most of the rest, as well) from my 25 favourite movies list (which needs an update). Thus, if you have the time (even if you are not per se a couch potato), go for it: they've got an impressive collection. You can search for the titles of the movies in English: don't be put off by the Chinese, should you not understand it :-). It might be of course just a matter of time before Tudou will also have to start removing some of its material because of copyrights infringement (I am not sure to what extent that is a problem already, but at least concerning recent movies such as Sweeney Todd, the likelihood of foul play is very high...), but the Chinese legislation in context appears to be more than lenient for the time being.

Econlinks for 06-02-'08

• Why we kiss, in case you were wondering... Not much to do with economics per se, unless you want to make the link to things some people consider related, such as when to say "I love you" (4th bullet point):-). And come to think of that, let's travel one year back in time and (re)consider the (neuro)science of love. Finally, keeping it assorted, you might also want to (re)check why you (don't) have sex (4th bullet point).

• 'Economics according to Google': a very interesting interview with Hal Varian, the currrent Chief Economist at Google. The interview was taken just a few days after Varian took over his new (full-time) job. Retain Varian's prediction: "I think marketing is the new finance".

• Sell illegal US immigrants the right to stay: wise thoughts (far too wise for any of the current US politicians) from Gary Becker; read also his former posts related to this topic: here, here and here).

• For those of you in any way interested in computing power, here's the most recent top 500 list of (commercially available) supercomputers (Nov '07), with all kinds of statistics available. Here's a PDF on the interpretation of the Top500 data.

CES 2008 and Bill's last keynote speech

SciAm's full coverage of the '08 CES. From where surely you won't miss the Bill Gates bits: Bill on the future of robotics; Bill giving a personal tour of MS's new "surface". And, of course, Bill's last CES keynote address, fully available for instance on YouTube (parts 1, 2, 3, 4, 5, 6, 7, 8, plus of course, the end-- where Bill has his Guitar Hero moment & Slash literally rocks). You might as well just forget the noise around the Vista... or not :-).

To admire: Women through the ages

A treat for Saturday afternoon: creativity+ superlative art + modern technology=3 minute video overview of 500 years of female portraits in Western Art-- with a most appropriate Bach's 'Sarabande", interpreted by Yo-Yo Ma, in the background. See it on the Saatchi Gallery blogs. Or, alternatively, on YouTube. You can also read the full information on each of the 90 portraits included. Enjoy!

The importance of cooperation in the production of knowledge... or of anything valuable, for that matter

Here's a link to an older post I wrote on the importance of team building (particularized for Romania) and I paraphrased Graham Bell in the end of it, just as I had done here (in Romanian).

A very interesting recent report in Science, "The Increasing Dominance of Teams in Production of Knowledge" (subscription needed to view the full PDF), by three researchers from Northwestern University, makes the point above very clear for the specific area concerning production of scientific knowledge (in any discipline).

We have used 19.9 million papers over 5 decades and 2.1 million patents to demonstrate that teams increasingly dominate solo authors in the production of knowledge. Research is increasingly done in teams across virtually all fields. Teams typically produce more highly cited research than individuals do, and this advantage is increasing over time. Teams now also produce the exceptionally high impact research, even where that distinction was once the domain of solo authors. These results are detailed for the sciences and engineering, social sciences, arts and humanities, and patents, suggesting that the process of knowledge creation has fundamentally changed.

Stephen Dubner, on Freakonomics, touches on the same idea when explaining YouTube's success (though this is also about carefully selecting your team mates, previous succesful projects being priority sets...).

Art moments: Photo-realist painting & Bio-design

For today very briefly about two of my favourite modern artists, active in completely different domains, and their fascinating work: Bert Monroy, a "photo-realist" painter, and respectively, Luigi Colani, a bio-designer.

• Bert Monroy's motto:

"As a photo-realist painter, I have often been asked why I don’t just take a photograph. Good question, when you consider my paintings look like photographs. Well, for one thing, I’m not a photographer. To me, it is not the destination that is important—it is the journey. The incredible challenge of recreating reality is my motivation".

Since I'll be in Chicago for a conference at the beginning of May, perhaps there'll be a chance for me to actually see the place the artist is creating in "Damen": by all acounts, this is impressive!

• Luigi Colani's motto:

"Whenever we talk about biodesign we should simply bear in mind just how amazingly superior a spider’s web is to any load-bearing structure man has made – and then derive from this insight that we should look to the superiority of nature for the solutions. If we want to tackle a new task in the studio, then it’s best to go outside first and look at what millenia-old answers there may already be to the problem."

Colani's work is currently displayed at London's Design Museum. And I really hate the fact that it seems impossible for me to make it to London before June 17 until when his "Translating Nature" exhibition runs... Here's a glimpse of what I'll miss.
