"You see this little hole? This moth's just about to emerge. It's in there right now, struggling. It's digging it's way through the thick hide of the cocoon. Now, I could help it - take my knife, gently widen the opening, and the moth would be free - but it would be too weak to survive. Struggle is nature's way of strengthening it."
--Locke (Lost, 2004)

Class Syllabus

Text: Princples of Mathematical Analysis, by Walter Rudin. This book, affectionately called "Baby Rudin" was published in 1976 and to this day remains the gold standard of introductory real analysis texts. For an idea of why it is the best, read this friendly review.

Francis Su of Harvey Mudd College taught Real Analysis in 2010 (using Rudin's book) and the lectures were videotaped and put on YouTube. Professor Su is one of the finest teachers in the country, and was the first recipient of the Henry L. Alder Award for Distinguished Teaching, a national award given out by the Mathematical Association of America. These lectures are not a substitute for attending class, but are a great supplement. Also check out Rudinium.

• Good mathematical writing is difficult. It takes hard work and practice to acquire this skill, and developing it is of the primary goals of this class. Francis Su has written a very nice 4-page essay on the topic.

• The late Evelyn Silvia taught real analysis out of Rudin at UC Davis. She wrote a set of companion notes to go along with Rudin's book.
