Why Balloons Rise and Apples Fall

Everything we do is touched by physics. Whether were on the motorway, at the beach or in the pub, its laws tell us what happens in our world and why. From the big stuff (life, the universe and everything) to the small stuff (the mind-bending world of quantum physics), here is an accessible guide to the fascinating, awe-inspiring and sometimes downright weird world of physics. Learn about why heavier things dont fall faster, why you have more energy when youre sitting upstairs, and why time slows down as you speed up, and consider such philosophical questions as whether you can be invisible, and what happened to Schrdingers poor cat. If you dont know your conduction from your convection, or your wormholes from your Ohms law, this is the book for you.
