How We Review Books: The Richter Scale A “magnitude 9” book does not mean that it is better than “magnitude 8” book, only that it shook me more at the time. This is because at QUAKE books, there is no such thing as a “good” vs “bad” book because if you are just focusing on “good” vs “bad” you are losing out on the opportunity to improve and grow!!There are plenty of other sites that will tell you if a book “sucks”. But I won’t. QUAKE Books is different. It tells you how hard a “bookquake” registered on the Richter scale below and what the aftershocks were.The scale, as with the one that measures earthquakes, is logarithmic and this means that the magnitude of a bookquake is determined from the logarithm of the amplitude of waves recorded by specially developed QUAKE Book seismographs. Each whole number increase in magnitude represents a tenfold rise in measured amplitude and releases about 31 times more energy than the amount associated with the preceding whole number value.AftershocksAftershocks are those impacts that are expected to last long after the book has been read and the initial dust has settled. The actions and thoughts expressed as aftershocks are those that will reverberate with us during a significant part of our lifetime. They might, in some cases, reflect final thoughts or how the book will continue to challenge us in the future. A true QUAKE book is like a good friend, one whose advice you never tire from.Finally, we are ALL field agents, on a quest “to be more able” and “improve by 1% each day”. If you too have experienced a bookquake that the world should know about then click the “Shook me” button, or alternatively, and if you would like, recommend me a QUAKE book.If you feel really moved to tell me about your personal bookquake and would love to share it with the QUAKE Books then please don’t leave before filling out a QUAKE REPORT.
