Most of us have heard of Albert Einstein, but how many of us actually know and understand his theories and, later, discoveries? Looking back in time, this book introduces students to Einstein and another famous scientist, Isaac Newton. Centered on the findings of the two researchers, this book uncovers the inner workings of gravity, heat, electricity, energy, and light. This book provides readers with the knowledge they need to understand simple things that are part of our daily lives: keeping our feet on the ground, playing with magnetic toys, and listening to music, to name just a few.

Physics is everywhere -- Newton's laws of motion -- Gravity -- Waves -- Heat and energy -- Electricity and magnetism -- Secrets of light -- Invisible rays -- Hidden forces -- Einstein's universe.
