^The Kaleidoscope Discovery Engine:
   "When we examine discoveries in science and mathematics, in
   hindsight we often find that if one scientist did not make a
   particular discovery, some other individual would have done so
   within a few months or years of the discovery." - Clifford
   Pickover

   This is also true in other advances in human discovery, not just
   science or mathematics. There's a "the time is right" about new
   things: Throughout my own life, I've invented things only to
   either a) find the discovery was done 6 more prior or b)
   somebody else comes up with a month before or after me.

   But I don't fret: a good idea is a good idea no matter where it
   comes from. And I take pride in knowing that either I was on the
   right track, or, at the very least, I'm not alone in my ideas.^
