Presh Talwalkar surely took a liking in writing ebooks with mathematical problems! In this new work, he chooses to talk about paradoxes, a theme which fascinates people since the time of Zeno. A paradox, mathematically speaking, is a situation where alongside (in Greek, "para-") one opinion ("-doxa") there is another one which is mutually exclusive.
The paradoxes in the ebook are divided in three broad categories: logical, probabilistic and from game theory (Mr Talwalkar studied mathematics and economics, so the last group comes naturally). There are classical ones, nearly classical ones (Simpson's Paradox and Monty Hall problems are well known in the circles of people liking such themes), but also paradoxes quite recent, and really puzzling. But as usual the value Mr Talwalkar adds lies in the exposition of the material; he always starts with examples grounded to earth, and explains in detail what happens, and why it happens. Moreover there is a bibliography which allows the interested reader to explore further the problems in the book.
If you like paradoxes, or if you fear paradoxes, the ebook is for you!
