Three stories about speed, volume, and probability:

SpaceX’s Falcon rockets propelled astronauts to 17,000 mph. At that rate, the rocket would travel from New York to Los Angeles in nine minutes.

Meanwhile on the other Florida coast, the Three Sisters Spring disperses enough water to fill a bathtub in the blink of an eye.

And on Wharton Moneyball, Eric Bradlow said:

“We have metrics in baseball that give us a sense. Suppose I told you that not wearing a mask was the equivalent of smoking half a pack a day or driving three thousand miles without wearing a seatbelt.
