I don't disagree with your thesis, but: understanding a solution to a problem, and coming up with the solution are two vastly different things.

  Not unlike P and NP
  • jjbinx007 11y ago
    Exactly. I always thought magic tricks exploited P vs NP... once you know how a trick done it seems obvious, but there are so many things to rule out before you find the right answer.

  Yes! It takes the Universe billions of years to produce a cow. It takes that cow less than a year to produce many more cows.

    Just one cow actually. If you're lucky you might get twins or three cows in two and a bit years but not many cows. Almost always just one. Sorry to be a pedant ;)

      Whoops, I was thinking of puppies when I wrote cow. Need to get more sleep!

  While that's true, it's beside the point. In this case, it's all about finding and formulating the problem. The solution is the easier bit. Consider this - how many of us have crossed off "m" on both sides of m d^r/dt^2 = -GMm/r^2 without actually noticing the problem with that? We're equating "mass" as associated with inertia and "mass" as associated with producing the gravitational effect. This is the central point from which pretty much all of GR emerges.
