This article is an example of everything I don't like about Hacker News. The author decries everyone's supposedly "black and white" world, but commits a far greater sin by replacin…

1. I plan to learn some category theory, differential/algebraic geometry, abstract algebra, and topology, in order to apply them to Haskell/Fortran programming and quantum optics. …

Consider the solution to the quadratic equation x = (-b ± sqrt(b^2-4ac))/(2a) What is x? What is a? The wonderful thing about math is that it doesn't matter. x could be length, dol…

At work (I'm a physics/mathematics guy developing quantum optical simulations): Fortran 2003/2008 C++ LaTeX Sage Mathematica Haskell (My initial experiments look promising; ghc+llv…

Emacs, but it's still hard to do. That code excerpt is nothing compared to what I have worked with in some code I no longer I have access to; some of the formulas stretched on for …

I work on numerical simulations, where I deal with colossal arrays of floating point numbers on hundreds or thousands of nodes. I want tools that can help with the following: 1. Vi…

I think it's pretty obvious what I'm talking about. The comment I was replying to suggested that people would be imprisoned for thoughtcrime. The original comment was disagreeing (…

People like you scare me, because you are so ignorant of history. While we might be heading towards a uber-PC socialist nightmare, one could argue just as easily that we'll end up …

Thanks for the reply; I was wondering what key that it shifted to, since everything sounded weird when I tried it. I just do this stuff by ear and guess the key, but I've never had…

Actually, this is a fairly unusual song, in music theoretical terms. Almost all pop songs use the I, ii, IV, V, and VI chords, with popular progressions including I-IV-V, ii-V-I, a…

There's another article that makes an attempt to disentangle nature and nurture in the sex gap at http://www.lagriffedulion.f2s.com/math2.htm . Like I mentioned earlier, these arti…

If the PC police could do Fermi problems, they wouldn't be polluting my news feed with inane conspiracy theories. http://www.lagriffedulion.f2s.com/math.htm
