Quite a number of mathematical theorems prove that the power of mathematics has its limits. But how relevant are these theorems for science? In this video I want to briefly summarize an essay that I just submitted to the essay contest of the Foundational Questions Institute. This year the topic is “Unpredictability, undecidability, and uncomputability”. You can read all the essays here: https://fqxi.org/community/forum/category/31427 In my video, I briefly go through Gödel's theorem, the Halting Problem, Wang's Domino Problem, uncomputable numbers, and the Real Butterfly Effect.
