Undecidability in Mathematics and Physics

Saturday, May 13th, 2023

This is a 3 part exploration of connections between quantum indeterminacy and Gödel’s incompletenes theorem (and Turing’s uncomputable number theorem…). Engaging and interesting but important for getting at the way branches of thought are uncomfortable with relationships they can’t control. The third installment has a gripping refutation of Bostrom’s simulation hypothesis on the grounds of quantum state randomness and world state incomputability via Cantor’s diagonal method… Provocative and fun.

Part 2 and part 3

Ciechanowski's Bicycle

Thursday, March 30th, 2023

Amazingly beautiful reflection on the design of the bicycle: how an intersection of physics and human morphology produce an icon of liberation and aesthetic elegance. With captivating visualizations.
