دانلود کتاب No Wonder You Wonder!

This book explores and explains scientific mysteries and principles, leavened with tongue-in-cheek humor and an abundance of illustrations. Chapters are short, but give an understanding of technology and science not available elsewhere. Questions include:

• What holds a satellite up while it goes around the Earth? • Why is the sky (made out of clear air!) blue instead of green, or just black as night like the sky that high altitude jumper Felix Baumgartner saw? • How is laser light different from “normal” light? • Did Columbus really discover that the Earth is round? • Which one invention will assuredly survive our civilization? • Why can’t you travel back in time?

If you often feel embarrassed because you don’t have a clue about lasers, the difference between volts, amps and watts, or how jet planes really work —but you would like to understand the physical principles of our modern world, whether you’re a teen or a parent— this book is for you!

To understand the basics of quantum mechanics, or of protons, neutrons and electrons, you don’t need algebra, calculus, or a lot of equations or technical buzzwords. Too many people have been soured on science by science teachers who have made simple concepts seem complex. This book is the antidote: all it requires is your curiosity.
