Some day you'll say "Sure, three. Protons, neutrons, and electrons, why?" and your kid will look at you and laugh right in your old-timey, went to school in the 20th century face.
Because she'll be all, "But dad, Garrett Lisi's Theory of Everything that maps all 243 subatomic particles onto the exceptional Lie group E8 was announced in like 2007--it was even at TED. How could you not know that?"
And your only hope for redeeming yourself with your 21st century child is to reply, "You can have your Garrett Lisi. I'll go straight to the source: Philip Glass and Sesame Street."
