— facts —-

*a breakthrough math proof:*

- one of the most sweeping results in math
- this proof looks at mathematical descriptions of change
- in math: these descriptions are called dynamical systems
- they apply to everything: from the motion of planets — to fluctuations of the stock market
- math model examples: swinging of a clock pendulum • water flow in a pipe • number of fish each spring in a lake
- wherever dynamical systems happen, researchers need to understand basic facts about them
- can dynamical systems — no matter how complex — be broken-up into random + deterministic elements?
- this math proof gives researchers the building blocks for understanding random change

story title: Proof finds that all change is a mix of order + randomness

deck: All descriptions of change are a unique blend of chance + determinism.

deck: According to the sweeping math proof of the weak Pinsker conjecture.

story title: How randomness can make math easier

deck: Randomness would seem to make a math statement harder to prove.

deck: In fact, it often does the opposite.
