Infinity is bigger than you think - Numberphile
Numberphile
Numberphile's James Grime explains Cantor's result that some infinities are bigger than others, including why the reals outnumber the integers. It is a short, accessible introduction to countable and uncountable infinity.
HN people recommend it as a clear introduction to different sizes of infinity that non-mathematicians can follow.
