 Mar17 comment Can you recommend a book to learn to teach math to a child? Seriously? Polya for 5-12 year olds? Dec18 awarded Notable Question Nov22 awarded Yearling Oct14 comment Pointwise vs. Uniform Convergence This is a very interesting perspective. This answer should have more upvotes. Sep24 awarded Autobiographer Sep16 comment Let the function $f:[a,b] \to \mathbb R$ be Lipschitz. Show that $f$ maps a set of measure zero onto a set of measure zero You can show that a Lebesgue measurable set may be expressed this way from Theorem 11 part iv (page 40) in Royden's Real analysis text. (This problem is from Royden).
