Apparently Christian fundamentalists are taking a dislike to set theory. Perhaps because "there is only one infinity and that's God". And perhaps because it's against common sense.

"William Press and Freeman Dyson have discovered a new class of strategies that are quite surprising. One thing they found is that I can decide what I want your score to be, and play in such a way that your average score is whatever I decided."

Editing text is like handling exceptions backwards. A curious observation, with the help of category theory.

"The food pairing hypothesis is the idea that foods that go best together contain similar molecular components. While this sounds elegant, Ahn and his collaborators set out to determine whether or not this is true."

Some possible answers to: "Multiple Choice: If you choose an answer to this question at random, what is the chance you will be correct? A) 25% B) 50% C) 60% D) 25%"

"That was the question on my mind while walking out of an hour and a half meeting which was attended by 6 people. The problem wasn’t that complicated, we went into the meeting with 3 alternative solutions: so why did it take so long to pick one? It kept nagging me a bit and then I recalled the “Simple Architectures for Complex Enterprises
” book by Roger Sessions. By applying his approach I was able to determine if we made the right choice and I’ll describe the results below."

"The idea is to provide a knowledge container that’s as easy to author as documents, but with the interactivity of apps—for CDFs to make live interactivity as everyday a way to communicate as spreadsheets made charts."

"Yesterday we bought you news of the media’s formula for determining how much coverage should be given to a murder victim or missing person, and today we can reveal an exclusive copy of those guidelines."

"One of the most interesting patterns that has ever been constructed in Conway’s Game of Life is primer, a gun that fires lightweight spaceships that represent exactly the prime numbers. [...] The gun works by firing lightweight spaceships westward, and destroying them via glider guns that emulate the Sieve of Eratosthenes. A lightweight spaceship makes it past the left edge of the gun at generation 120N if and only if N is a prime number (though for technical reasons, 2 and 3 are not outputted)." Holy moly. I had no idea Conway's Game of Life had any significant mathematical uses, let alone this.

So, maybe the P=NP problem remains open: "There are two camps in our community on Deolalikar's [P != NP] paper. Those of us who saw Deolalikar's paper as just another in a long series of bad attempts at P v NP and wondering what all the fuss was about. [...] Deolalikar at this point should retract his P ≠ NP claim until he can address all these issues. In an email Deolalikar sent out to the gang of 22 on Friday the 13th, he restates his claim and overview of the proof and says he "fixed the issues in the finite model theory portion of the proof". He promises a revised version on his homepage in a couple of days. Deolalikar is following the script, currently at stage 5 of the 12 stage process. Stage 6 will happen soner than he expects." The 12 stage process, linked, is particularly damning.
