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?
