dansmathcast #19 / it's all about the love (for math) / visiting higher dimensions / quadratic equations / fan mail from Po / reflecting on parabolas and hyperbolas / a really bad math joke!

lots of you have been downloading dansmathflix #2 (even though it weighs in at over 90 MB); i'm very happy about that! i'll produce more animations and things this fall... i'm now working on podcast 19; you can leave a comment in iTunes! keep sending questions, i read some on my show!

dansmathcast #18 - hot on the heels of the release of my blockbuster film - this episode looks at color numbers and systems, square root expressions, the great Ramanujan joins dan's math hall of fame, learn some reflection properties of circles and ellipses, and try a new type of math joke!
