Flatterland is sort of an unofficial sequel to Abbott's classic Flatland, written in modern non-Victorian English. Although Victorian English gave the original a pretty classy feel, Flatterland doesn't disappoint. Its aim is similar to that of the original: To explain new mathematical concepts to lay people in lay language.

The book succeeds brilliantly. It's filled with illustration to help visualize the concepts, and the stories around which the concepts are introduced are reminiscent of Alice's Adventures in Wonderland (well, the fact that chapters have names like The Topologist's Tea-Party and Along the Looking-Glass probably helps), and this gives the book a whimsical tone (that's a benefit). Here's a sample:

"Is Planiturth's universe built from mathematics? Or is mathematics built by the minds of Planiturthians? Planiturthian mathematicians would like to think that their universe is built from mathematics, but that's only natural, after all. Planiturthian physicists would like to think that the Planiturthian universe is built from physics. Planiturthian biologists would like to think that the Planiturthian universe is built from biology. Planiturthian philosophers would like to think that the Planiturthian universe is built from philosophy. (Let me tell you a secret: it is. The fundamental unit of the Planiturthian universe is the philosophon, a unit of logic so tiny that only a philosopher could hope to split it.)"

The book also ventures a little into physics, explaining things like the Schrödinger's cat, the double-slit experiment, time travel, and forces. But the meat of the book is mathematics.

This is only partly a book about evolution. In the last chapter (The Replication Bomb) Dawkins speculates on ten thresholds that life goes through on its way to interstellar emigration. (The analogy is to a supernova. Just as a star can go supernova, a planet might explode with life.)

The book also goes through some very neat experiments on bees and the evolution of a bee dance that codes for location of food.

A collection of imaginary letters to a young contrarian. The beginning of each letter imagines that the reader has sent a reply to the previous one, and the current one is a reply to that, so that reading the book seems to be a conversation. The book deals with how to be a public intellectual with contrary views, and how to deal with all the hardships that come with that obligation.

It's a very short book, and once started, it's very hard to put it down. Hitchens is a very eloquent writer, besides being knowledgeable and engaged. In the book he deals a little bit with his public confrontations (his criticism of Mother Theresa and Henry Kissinger, for instance), really as examples for pontificating on the life of a contrarian. There's a little part of the book that I liked where he explores various words for a contrarian, such as rebel, revolutionary, and an "angry young man".

Letters to a Young Mathematician is written as an update on G. H. Hardy's classic A Mathematician's Apology, but the book is not an exercise in apologetics.

"Attitudes change. No longer do mathematicians believe that they owe the world an apology."

It follows an imaginary girl, Meg, from her school years through her ensuing career, and each chapter is a letter to her at crucial steps in her career. Some parts are musings on math (pure vs applied) while others are specific career tips (solitary work vs collaboration). The book is virtually devoid of any actual math, so I think it's safe for mathophobes. In fact, for this very reason, it might even help to partially cure the phobia of those unfortunately inflicted.

I really liked the light-hearted way the book is written. Perhaps someone who is planning on embarking on a mathematical career would enjoy it even more.
