Ten interesting facts
The Secret of the Blue Sky and Other Profound Answers to Simple Questions
Author Name: John Gribbin
Have you ever wondered why the sky is blue during the day and dark at night, the secret behind the salty taste of blood, why men are taller than women, how fast the continents move, how old the sun is, or how we know that Einstein was right? You'll find the answers to these questions and more in this wonderful book, with which John Gribbin continues his series of fascinating books on cosmic phenomena. However, here he takes an opposite approach. Having previously presented some simple answers to complex questions, in this book he provides us—based on proven scientific evidence—with profound and detailed answers to such seemingly simple questions.
