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.

CORRECTION: An earlier version of this piece gave an incorrect location for the Animal Medical Center; the correct location is 510 East 62nd Street, New York, NY. The piece also featured an incorrect estimation of the rate at which falling cats were seen by the Animal Medical Center over a five-month period; the correct rate was approximately one cat per day. The audio has been adjusted to reflect these changes.
