Redshift
The light emitted by celestial objects can have its wavelength "stretched" in different ways before it is observed by astronomers. These stretching phenomena are collectively called "redshift". They influence virtually all aspects of astronomy and even underpin the "Big Bang" theory of the creation of the universe. This book details the types of redshift and explains their myriad of uses. It begins by introducing the nature of light and the problems involved in measuring its properties. After explaining the redshift phenomena and their uses, the book touches on the age and size of the universe; two subjects embroiled in controversy because of our current interpretation of the redshift. Less conventional theories are then expressed. As a by-product of the explanation of redshift, the book offers the reader a basic understanding of Einstein's theory of relativity. Mathematical treatments of the concepts introduced in the text are boxed off and should not detract from the book's readibility, but allow it to be used as a textbook by students of astronomy at all levels. It is also suitable for astronomers and astrophysicists, amateur astronomers, and any science enthusiast.

About the author
Stuart Clark
90 books44 followersStuart Clark was born in England in the sleepy little town of Ashford, Middlesex. To those not intimate with British geography, that can more simply be described as Greater London.
Science, particularly Biology, always interested Stuart and after school, he went on to Bristol University where he graduated with a BSc in Microbiology.
He worked for two years as a technical author for a large scientific publishing company before deciding that he really wanted to go back to University and do a Masters degree in Science Communication, which he completed at Imperial College, London.
After years of intermittent study and work, Stuart decided to take a sabbatical and spent almost two years experiencing the sights and sounds of Australasia and South-East Asia. He spent a year of that time living and working in Sydney, Australia.
When he’s not working or writing, Stuart spends his time scuba diving and attempting to play golf.
Stuart emigrated to the United States in 2005 and now lives with his wife and daughter in New York.
