Despite the title, not once in this book is an actual mathematical problem presented coherently. Instead, Cole drones on about the virtues of cooperation, the importance of minorities, and other left-wing philosophical themes. I'm a liberal and would tend to agree with her politically, but that ignores the central problem with this book: Cole's failure to make the distinction between mathematics itself and beliefs that just happen to be justified by statistics or quasi-mathematical reasoning.
Perhaps The Universe and the Teacup is best described as a meta-popularization, since virtually all of Cole's sources are themselves popularizations. She hypes such familiar staples of popular science writing as fuzzy logic, chaos and complexity theory ("all the rage these days" -- I thought that's what they said back in the 80's), and Godel's theorem (both "a shattering blow" AND "a staggering blow to our sense of certainty"), without showing that she understands any of these things on more than a superficial level. (I don't claim to be an expert on these topics, either, but then again I didn't write a book about them.)
For general readers interested in how mathematics relates to everyday life, I'd recommend John Allen Paulos "Innumeracy"; for a survey of modern mathematics, both "From Here To Infinity" by Ian Stewart and "Archimedes' Revenge" by Paul Hoffman succeed where "The Universe and the Teacup" fails.
