The Drunkards Walk – Book Review pt 1

I’ve been reading The Drunkards Walk – How Randomness Rules our lives. Really interesting! The main points being:

  • most things depend on chance – many more than you might think
  • Humans are really, really bad at understanding chance and probability
  • The history of math (and probability in particular) is really interesting.

Some examples: ‘

Hot hand’ or streaks in sports (and movie producing, and corporate earnings, and investment returns) are accounted for by random chance, _even though they seem like they aren’t_. Firing the coach or CEO for bad  team performance is basically performative.

The notation we use today is relatively recent. The equals sign was invented not that long ago, + and – have been used for a while, but not in the way we use them today. This makes the development of early mathematics even more amazing. I want to make a timeline of developments in Math.

Two students miss an exam and lie to the professor: we had a flat tire. The professor asks each of them separately: which tire? What are the chances they both pick the same one? (1 in 4, although my intuition says 1 in 16 or higher).

More late on the methods used to determine probability, so I can maybe remember this another day.
