“And now I’ve got an an even more thorough explanation of Monty Hall problems and of the psychological processes that allow us to get suckered”.

“"fast multipole method" developed for computational physics to rapidly estimate (to arbitrary precision) the conjugate gradient of an error function. (In other words, they tweak the parameters and "get a little better" the next time through the training data.)”

"I was stunned," Schipke says. "It was like finding a picture of Bill Gates in the Dead Sea Scrolls. The colophon [the title page] named the copyist as Udo of Aachen, and I just had to find out more about more...

“100% Kelly strategy marks the boundary between aggressive and insane investing”

Q. How can I find the priors for a problem? A. Many commonly used priors are listed in the Handbook of Chemistry and Physics. Q. Where do priors originally come from? A. Never ask that question. Q. Uh huh. Then more...

A sculpture of the Flying Spaghetti Monster, the supreme deity cooked up to protest a Kansas legal battle over evolution, went on display outside a courthouse in Cumberland County, Tennessee, late last month.

The Monty Hall Problem has struck again, and this time it’s not merely embarrassing mathematicians. If the calculations of a Yale economist are correct, there’s a sneaky logical fallacy in some of the most famous experiments in psychology.

If you want to learn math and programming, this is one of the best places to sharpen your skills. Addictive and emotional roller coaster too.

Solving an original and addictive number puzzle gives you karma to spend.

In the old days, Bayesian methods at least had the virtue of being mathematically clean. Nowadays, they all seem to be computed using Markov chain Monte Carlo, which means that, not only can you not realistically evaluate the statistical properties more...
