# Patterns in Sports

There is no time for thinking in sports. Thinking is just too slow. Reactions must be engrained and subconscious. Consider baseball, America’s pastime.

The average fastball of a MLB pitcher is 95 mph. A 95 mph fastball takes 400 milliseconds to reach homeplate. The average human reaction time is 250 milliseconds which leaves ~200 milliseconds to recognize which pitch was thrown, where it will cross home plate, and when to swing. This isn’t enough time to get the job done. Hitters need more time to swing. There are two ways to overcome this problem.

1. Quicken Reactions
2. Pattern Matching

Since reaction times decrease with age and fatigue, pattern matching is the only sustainable solution for long term success. …

# The Cataclysm Sentence for Jiu Jitsu

If COVID19 creates a zombie apocalypse, what single sentence can transfer all knowledge of jiu jitsu?

Radiolab recently released an episode that started with Richard Feynman’s first lecture in his Introduction to Physics 101 class at CalTech. He starts the lecture by posing a question then answering it:

If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. …

It was Denver’s snowiest Thanksgiving in 40 years. This storm dropped so much snow that I had to leave a day early and grab one of the few hotel rooms left.

My hotel room neighbors partied all night. They clearly had multiple rooms and went back and forth between them. And they slammed every door each time. Needless to say . . . I slept poorly.

First the snow storm. Then the neighbors. Now I had to fight Thanksgiving Day travelers to get to my flight.

The TSA lines were the longest I had ever seen at DIA. They were double-wrapped around the security area for both the East and West security gates, and I still needed to check in. Of course I had to check-in on the other side of the airport. …
