Brand-new special edition from BBC Focus – The Big Book Of Why?

Aimed at curious readers aged anywhere between 9 and 90, The Big Book Of Why? solves a wide range of scientific questions and conundrums about how life works. With answers provided by the crack team of experts behind BBC Focus, every page offers enlightenment and revelation. Why do we have wisdom teeth? Why do tigers have stripes? And why is it safer to sit backwards on a plane?

Also, a special How It Works section reveals the cutting-edge thinking and engineering behind the latest technology – from Formula E racing cars to robot exoskeletons.
