The linked article appears to describe the behavior of a classic textbook malignant narcissist -- I mean either the author of the piece, or his subject, falls into that category. Maybe both. More here: http://arachnoid.com/C

Yes -- well, 1/2 the area of a unit circle, which is why I multiply by 2. I used Sage ( http://www.sagemath.org/ ) to create these quick results: f(x) = sqrt(1-x^2) 2 * integrate(f(x),x,-1,1) Sage replies: p

I like the movie, it deserves its fame, but there are some errors in the script that could have been easily avoided. For example, at one point a character says something to the effect of, "Surely they've printed out every 216-digi

Yes, true, but the irony here is that the introductory paragraph is itself a nerd litmus test. No nerd deserving the title would accept it as written.

Remember the role of axioms, which another poster has explained in a different way. The issue in question (not itself an axiom but one that requires acceptance of axioms) is whether each composite (i.e. non-prime) is uniquely composed of pr

That reads like an Onion satire. If it's literally true, it's very depressing. And I suspect it's literally true, at least for some women.

I wish people would use the word "nature" instead of "god" in public lectures and writings, to avoid seeming to lend credence to revealed religion. Insiders know exactly what Einstein meant by the word, but the problem i
