OnSeptember , afteryears of searching, gravitational waves were detected for the first time and astronomy changed for ever Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X rays and the rest But gravitational waves ripples in the fabric of space and time are unrelenting, passing through barriers that stop light dead At the twokilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movementtimes smaller than the nucleus of an atom Inthey spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering This was the first time black holes had ever been directly detected and it promises farfor the future of astronomy Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe clear and informative Good book for the subject. Disappointing, too long hothead same could be written in far fewer words Written like a story, this book presents a pleasant and concise description of the history, with a bit of science, of the detection of gravitational waves This book is a nice read for gravitational waves enthusiasts. Only 50 percent through but good so far Book is good Explain everything I am not given 5 star because this book has some unnecessary content which is even not related to gravitational waves. Good for knowledge but averageEasy language to understand for kids I got this book to learn about gravitational waves Not about the quarrels between scientists or how much the telescope cost over budget, and who managed to get money for it, I'm surprised he never told us what was in their sandwiches each day I learned a little and a bit I would not recommend this book if you want to know about gravitational waves But ok if you like a story book. The direct gravitational waves observation not only confirmed previous indirect observation and one of general theory of relativity predection but it has opened completely new field of astronomy.The book will provide you with basic understanding what the gravitational waves are and how it is possible to detect them Moreover, the book serves also as a guide through history of a quest for gravitational waves The author also provides a brief history of theory of gravitation, going from ancient Greeks to Newton to Einstein After that the author focuses on Weber's discoveries in 60's and of course on interferometric observatories like a LIGO The author also provides description of hurdles the team had been building the LIGO had to face and some stories of persons behind this project.It is true that the book is a little bit brief, however, it can serve as introduction to the problem To advanced readers or somebody interested deeper in gravitational waves I would recommed the book Einstein's Monsters: The Life and Times of Black Holes by Chris Impey (also available on ) I read them both and enjoyed them both.What a little bit disapointed me about the book is a few mistakes like that the Universe became transparent after third a bilion of years According to current theories, it occured 300 thousand years after the Big Bang Aparently bilions and milions were confused Sometimes, the author used wrong units etc But despite this, the book is well writen and easily comprehensible.
