Simon has started a little video series about the Irrationality of Square Roots.
In Part 0, Simon talks about what square root of 2 is and in Part 1, he presents an algebraic proof that root 2 is irrational. He learned this from Numberphile.
In Part 2, Simon presents a geometric proof that root 2 is irrational. Based on Mathologer’s videos.
Parts 3 and 4 following soon!
