Why Balloons Rise and Apples Fall

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 don’t fall faster, why you have more energy when you’re 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 Schrödinger’s poor cat.
