Graham Farmelo does an excellent presentation on the much underrated quantum physicist Paul Dirac. My only question mark is it seems Dirac had some signs of either autism or Aspergers syndrome.
Dirac's equations were described by his peers as "like fully formed marble statues falling from the sky".
My own experience on entheogens like DMT is that reality at a fundamental level is extraordinarily beautiful.
The geometry of it you might say.
