Introduction to number theory lecture 44 Pythagorean triangles

This lecture is part of my Berkeley math 115 course "Introduction to number theory"
For the other lectures in the course see • Introduction to number...
We apply the theory of binary quadratic forms to study pythagorean triangles with x^2 + y^2 = z^2
The textbook is "An introduction to the theory of numbers" by Niven, Zuckerman, and Montgomery (5th edition).

Thank you Professor Borcherds for your lecture. I like the style of your presentation and hopefully more mathematicians will follow in your footsteps.

Nelipe Feto not upvoting this video? I'm shocked, shocked!

I genuinely wish I'd understand half of the things mentioned in this video. Math seems so beautiful and elegant.

A little typo at 12:13, should be -7/25 not -7/25 i, but philosophy is nice.
