Obama orders Guantánamo closure
Two months ago, Obama promised he'd close Guantánamo prison. He has now signed an order that this should happen within a year from now. This shameful prison, established and maintained against all international laws and outcries, is going away. Now, here is a politician who keeps his promises.
On a lighter side, Obama knows how to speak English. He *can* pronounce the word "nuclear" as ˈnü-klē-ər. (Won't we miss Bush and his -isms?) Listen to it here, along with a promise to the muslim world that they will find an extended hand from the US if they unclench their fist.

Britannica goes public
Mimicking Wikipedia, the Encyclopaedia Britannica plans to let readers and contributing experts expand and maintain entries online. A while ago, Wikipedia was found to be about as accurate on science as the Encyclopedia Britannica.

Lennox vs Hitchens
Some time ago (August 2008), someone came up with the idea to have a debate between Christopher Hitchens and John Lennox on the (silly) question whether Europe should prefer the new atheism (whatever the latter means and whatever the verb "to prefer" means), as part of the Edinburgh International Festival. Well, the debate took place, Hitchens "lost", and Lennox pulled from his usual bag of naive arguments (based on pseud-science) to defend his faith. I was there, I asked some questions to Lennox, I received silly answers, I was interviewed by the BBC, and made some "friends" who tried to proselytize me by sending me several emails afterwards. I wrote about it on the blog wet lenses and so here's the link for the record of it.
As for Lennox, I've written about him before, for example, here and here.

Everything we see and everything we can’t see exists
This is NOT what I maintain. But this is what was claimed yesterday, the first day of Obama's presidency. Indeed, Obama chose Rick Warren to say that:
...everything we see and everything we can’t see exists...
How can a rational, thinking person not see the logical mistake (as well as the idiocy) of the above statement? The full text of Warren's speech is here.

What measure theory is about
It's about counting, but when things get too large.
Put otherwise, it's about addition of positive numbers, but when these numbers are far too many.

The principle of dynamic programming
max_{x,y} [f(x) + g(x,y)] = max_x [f(x) + max_y g(x,y)]
The bottom line
