E=MC²: Simple Physics: Why Balloons Rise, Apples Fall, and Golf Balls Go Awry / by Jeff Stewart

"What exactly is Physics? Well, in a way, it's everything." (p.1)
Physicists--including those who "enjoy smashing tiny bits of stuff into even tinier bits of stuff"--have no doubt that absolutely everything can be explained through physics principles simply because absolutely everything is subject to the laws of nature. Of course takes quite a bit of brainwork to understand said concepts such as the frequency of electromagnetic waves,
Newton's motion laws, relativity or, say, the magnetic flux within a transformer. And then to understand how all of creation including our own bodies and even our own thoughts can be described in terms of these seemingly complex theories can seem a bit daunting. Fortunately Physics Professor Jeff Stewart, along with the good folks at Blackboard Books and Reader's Digest, have come up with a fascinatingly simple way to understanding such things as Planck's Constant, Archimedes Principle or Kepler's theories on planetary motion. The book is divided up into carefully thought out sections outlining the various physics principles which are most relative to our everyday lives. It's fun and even humorous in places making it a good way to educate yourself on all those things which were forgotten after the test. (530 STEWART)
