Reduction of variables; excessive simplification in mathematics
  (and in theoretical physics) is fundamentally problematic, imo.

  I'll be 43 in 8 days (yay me). At 11, I got my first computer. I
  was in Pre-Algebra. I taught myself programming at home. I also
  learned Math at school.

  They're much different.

  I watch in bewilderment as I was supposed to cancel out
  variables to "simplify". So, in my mind, I just kept track of
  the variables, as I would have in a BASIC program at home. I
  mentally replaced the 2x with a "for x=1 to 2: x=x+x: next x"
  and thought in terms of processes rather than functions.

  So.. I'm a little biased against reductionism.
