The desire to trace your way back to the very beginning, to understand everything -- whether it's the mysteries of love or the mechanics of the universe -- is deeply human. It might also be deeply flawed.
We plunge into a black hole, take a trip over Niagara Falls, and upend some myths about falling cats.
Three stories that upend our pre-conceived notions about falling:
3. Falling Cats: David Quammen ponders the terminal velocity of a plummeting cat, teaches Jad a new word, and helps clear up some fallacies of feline physics.
4. Constantly Falling: Brian Greene explains why he can't answer the most basic question you can ask a physicist: "why do we fall?"
5. Falling Fortunes: Garrett Soden and Joan Murray introduce us to the 20th Century's greatest "gravity hero"--who, despite being the first person to survive a trip over Niagara Falls in a barrel, ultimately landed in a poorhouse.
Fighting the inevitable march of time -- or at least the common sense view of it.
The strange, subjective nature of time -- from a sped-up spin through childhood, to a really, really slowed-down Beethoven symphony.
