Показать описание
Undoubtedly, an important area to apply Logic to is Mathematics!

Previously we went through Direct Proofs with the textbook "Basic Mathematics" by Serge Lang. This video we'll do a Proof by Contrapositive and a Proof by Contradiction. These mathematical proofs will concern elementary Number Theory.

These are good motivating examples of proof by contra-positive and proof by contradiction

It really is quite mindblowing to just stop and consider that non-rational numbers exist

Excellent video, thank you. I am curious to know your opinion about chess as intellectual/logical training? I used to play chess quite a bit, and got to a point where I could beat the chess computer, but I never enjoyed playing against human opponents. I wonder what that says about me??
