Platonic Realms is an online math academy. It features a searchable encyclopedia with extended articles on things from Cantor's Theorem to Zeno's Paradox of the Tortoise and Achilles. You'll also find minitexts, such as "Coping with Math Anxiety" and "The Mathematical Art of M.C. Escher". Last but not least, a searchable math quotes database.
