John Stillwell is professor of mathematics at the University of San Francisco and an affiliate of the School of Mathematical Sciences at Monash University, Australia. His many books include Mathematics and Its History and Elements of Mathematics: From Euclid to Gödel (Princeton).

This book presents reverse mathematics to a general mathematical audience for the first time. Reverse mathematics is a new field that answers some old questions. In the two thousand years that mathematicians have been deriving theorems from axioms, it has often been asked: which axioms are needed to prove a given theorem? Only in the last two hundred years have some of these qu...(展开全部)

Is there a right way to study how the brain works? Following the empiricist’s tradition, the most common approach involves the study of neural reactions to stimuli presented by an experimenter. This ‘outside-in’ method fueled a generation of brain research and now must confront hidden assumptions about causation and concepts that may not hold neatly for systems that act and rea...(展开全部)

This revised and enlarged fourth edition features five new chapters, which treat classical results such as the "Fundamental Theorem of Algebra", problems about tilings, but also quite recent proofs, for example of the Kneser conjecture in graph theory. The new edition also presents further improvements and surprises, among them a new proof for "Hilbert's Third Problem". From th...(展开全部)

Keep Your Head Down. Don't Get Noticed. Or Else. I'm Trella. I'm a scrub. A nobody. One of thousands who work the lower levels, keeping Inside clean for the Uppers. I've got one friend, do my job and try to avoid the Pop Cops. So what if I occasionally use the pipes to sneak around the Upper levels? The only neck at risk is my own…until I accidentally start a rebellion and beco...(展开全部)
