I once played chess with Harald Helfgott back in the day. Way to go, Harald!
 
Busy day in analytic number theory; Harald Helfgott has complemented his previous paper http://arxiv.org/abs/1205.5252 (obtaining minor arc estimates for the odd Goldbach problem) with major arc estimates, thus finally obtaining an unconditional proof of the odd Goldbach conjecture that every odd number greater than five is the sum of three primes.  (This improves upon a result of mine from last year http://terrytao.wordpress.com/2012/02/01/every-odd-integer-larger-than-1-is-the-sum-of-at-most-five-primes/ showing that such numbers are the sum of five or fewer primes, though at the cost of a significantly lengthier argument.) As with virtually all successful partial results on the Goldbach problem, the argument proceeds by the Hardy-Littlewood-Vinogradov circle method; the challenge is to make all the estimates completely effective and to optimise all parameters (which, among other things, requires a certain amount of computer-assisted computation).  [EDIT: the proof also relies on extensive numerical verifications of GRH that were performed by David Platt.]

#ifihadglass  I would create a quantified self brain prosthetic. In addition to physical health, the focus would be on knowledge that a user comes into contact with throughout their day. It would be invaluable and indispensable; please see my earlier project: http://www.esquire.com/features/roger-craig-jeopardy-champ-0212
Let’s do it!

700 Terabytes in a gram of DNA breakthrough. Each of us has about 34 grams of DNA in us, so we each can store about 24 petabytes in our DNA

Pretty good quiz about a classic Simpsons episode. It's been a long time, so I only managed 11/24, how well can you do?

Does anybody know if GooglePlus/Google+ still has the contact form that emails you, but doesn't reveal your email address?

I think they want people to use "hangout" to do that... or just post some post with +Roger Craig so the post show up in that particular person's notification.

I don't think it make sense, but perhaps their marketing department is gradually gaining on engineering department.

Wikipedia has over 4 million articles. They neglect to tell you that 0.5% of them are on asteroids: http://en.wikipedia.org/wiki/Category:Main_Belt_asteroids

Barack Obama’s $787 billion stimulus package, enacted within a month of his taking office in January 2009, amounted to about 4% of America’s GDP. In the Depression of the 1930s, the biggest stimulus in any year of Franklin Roosevelt’s New Deal amounted to only about 1.5% of GDP http://econ.st/SaIMgW

Living in Chicagoland, I can't tell you the number of suburban cabbies I've reported to their dispatch office for a variety of different things (not taking plastic, complaining about a slow tip, etc). I've yet to have a reportable issue in a Chicago city cab.

Jeopardy! Tournament of Champions is being re-aired this week and next. I'm a little biased, but it's pretty entertaining!
