This isn't a book you can sit down and read, or at least I couldn't. It's a huge collection of mathematical trivia and random fun facts from history arranged in chronological order. The fun facts you could probably find anywhere but the mathematical trivia are fairly unique - there aren't that many radio hosts with a degree in mathematics.

The problem (or the advantage) is that there are an awful lot of these snippets in the book. Combined with the forced jollity and dad jokes, it means you won't get through a big fraction of it before you groan and drop it for a while. So probably best to just dip into it from time to time.

What I loved about this book was the anecdotal collection of historical factoids. Much of the math was beyond me, but even in short bursts the historical storytelling and humour were woven together in a totally engaging way.

Nice easy to read fact book. With some interesting facts inside. Didn’t enjoy the forced humour with the puns and bad jokes tho but it’s a relaxing book

Starting with the big bang and ending in the present day (with a few glimpses of the future for good measure) Time Machine is a history book unlike any other. Jam-packed with quotes, quizzes, anecdotes and trivia, Adam’s latest book is a full-colour treasure trove for ages 8... all the way to 108.

Will time travel ever be possible? And who (or what) is the Witch of Agnesi?
