Transcript

A person is giving a presentation, pointing at a screen.

Screen: 2-squared equals 4; negative-2-squared equals 4.

Person: Based on my analysis, both 2 and negative 2 are solutions to x squared equals 4. Therefore, the square root of four is zero.

Caption: The mathematicians responded poorly to my compromise theory.

Title text: I believe the truth always lies halfway between the most extreme claims.
