   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, dollars, area, volume, mass, potatoes, lines of code, chicke

   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 about 6 lines of 80 chars each. It's not so much the unbal

   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. Visualizing code. Rendering C++ and/or Fortran as LaTeX woul

   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 (slightly) with someone that has a very left-wing view of "

   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 in a hell like fascist Italy, where leftists were rounded u

   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 any music theory training. How do you recognize the key o

   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, and I-V-VI-IV. Since this is tonal music, it obviously incl

   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 articles are a few steps above Fermi problems; there are ways

    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
