  1. Jeremy Jeremy says:

    A kind of book I love, which takes a body of knowledge that most of us experience as a bare statement of fact in our education the Earth has a magnetic field that explains how compasses work and protects from radiation from outer space, and by the way it has flipped end for end multiple times in the distant past and lays out a detailed history of how we learned about it and how much we have left to learn Enlightening and entertaining.

    Great example of interesting science and history combined into a compelling story.

    I really enjoy books about science, and particularly ones that give an historical perspective to our ongoing discovery of scientific knowledge.On the subject of the Earth s magnetism, I have to say that I was almost totally ignorant I know that the Earth has magnetic poles, but that was basically the extent of my knowledge, and I am ashamed to say that it had never occured to me to wonder why the Earth should be magnetic I had no idea that the entire Earth is covered in a magnetic field that p I really enjoy books about science, and particularly ones that give an historical perspective to our ongoing discovery of scientific knowledge.On the subject of the Earth s magnetism, I have to say that I was almost totally ignorant I know that the Earth has magnetic poles, but that was basically the extent of my knowledge, and I am ashamed to say that it had never occured to me to wonder why the Earth should be magnetic I had no idea that the entire Earth is covered in a magnetic field that protects us from solar winds and cosmic ray particles Without this protective magnetic field, the Earth would be an uninhabitable planet.Gillian Turner is a British geophysicist, who works at Victoria University, Wellington New Zealand She describes this book as the history of a scientific quest that has spanned several millenia That quest was the drive to solve the problem of Earth s magnetism why is the Earth magnetic Is the magnetism generated internally or externally And most puzzling of all, how is the magnetism sustained The journey to understand this problem begins in 900BC, with the Greek legend of the shepherd Magnes, who went out to tend his sheep the morning after an electrical storm and found that his iron studded boots stuck to the rocks This was the first type of magnetism that was identified by humans the local magnetisation of rock that is rich in magnetite, an oxide of iron, after it has been struck by lightning This rock is known as lodestone.The interest in magnetisation really took off with the development of the compass and it s importance to ocean navigation Why did the compass needle always point north, but not directly to the geographical north pole Why did the variation between magnetic north and true north change from place to place across the globe Why did the needle dip up and down at different degrees depending on latitude The quest to answer all these questions involved some of the greatest scientific minds, and intersected with scientific discoveries regarding the calculation of longitude, the discovery of electricity and the development of geology Scientists playing a major role in this story include Halley, Gauss, Ampere, Faraday, Coulomb, Clerk Maxwell, and many .The final chapters in this quest for understanding are still to be written Major breakthroughs in understanding the magnetism of the Earth have only become possible within the last 20 years Prior to that, we did not have the supercomputers necessary to undertake the immense mathematical calculations needed to solve the equations that would explain the magnetic processes taking place within the Earth.I have to admit that a lot of the science in this book was way over my head, but I still got a lot out of it I learnt a huge amount and I really enjoyed reading about all the scientists involved in solving this puzzle, and as always I found myself totally fascinated by the way in which scientific knowledge grows and feeds off itself in a cascading domino effect.The only thing I would have likedof in this book would have been some discussion of the effects on life on Earth of such things as shifting magnetic polarities and the changing strength of the Earth s magnetic field On the very last page Gillian Turner provides us with the tantalising information that in the past 200 years the Earth s magnetic field has dropped by 15% an astonishing rate of change What does this mean If a weaker magnetic field means less protection from solar winds and cosmic rays, could this explain things like climate change and the hole in the ozone layer I really wish there could have been some discussion of things like this, but perhaps this historical account is not the right place for issues like that Maybe Gillian Turner will write another book that tackles these questions

    Although I knew most of the basic science regarding earth s magnetism from various other readings, this book tied everything together chronologically and in muchdetail In fact, after finishing it I added it to my History bookshelf as well as the Science shelf because it is so much about the various individuals that have contributed to our knowledge of magnetism since the beginning of the current epoch.I struggled between whether to give it three or four stars There are sections that were Although I knew most of the basic science regarding earth s magnetism from various other readings, this book tied everything together chronologically and in muchdetail In fact, after finishing it I added it to my History bookshelf as well as the Science shelf because it is so much about the various individuals that have contributed to our knowledge of magnetism since the beginning of the current epoch.I struggled between whether to give it three or four stars There are sections that were fascinating and deserved the higher rating but overall the book did not hook me as much as I would have liked It s difficult to say why At times some of the math or theoretical concepts were a little vague and, for me, could have usedexplanation, examples or analogies At other times it just moved a little slower than I would like.Since plate tectonics is an area of special interest for me, I especially enjoyed the section on how the discovery of sea floor spreading and alternating bands of oppositely polarized rock contributed to the proof of the plate tectonic theory of continental drift.I think if I were a student of geomagnetism looking for an overview of the history of the science I might have given the book the higher rating

    This reviewer knows precious little about geophysics, so will not be complaining, as others have, that this book was directed at a generalist audience I will complain however about the back cover I realize this is out of the control of the author, and the blame rests with the publisher, but it is a pet peeve of mine when cover descriptions do not match the contents of the book Here the back cover questions how birds and other animals navigate by magnetism yet the book does not deal with This reviewer knows precious little about geophysics, so will not be complaining, as others have, that this book was directed at a generalist audience I will complain however about the back cover I realize this is out of the control of the author, and the blame rests with the publisher, but it is a pet peeve of mine when cover descriptions do not match the contents of the book Here the back cover questions how birds and other animals navigate by magnetism yet the book does not deal with this topic at all, aside from a brief mention of the topic in the epilog Nor should this book deal with that topic.It felt overstated for me, in my supreme ignorance, for the book to claim that certain mysteries have been solved Indeed, theories have been proposed and are evolving Very little has been solved At best, we might claim that the answers have been hinted at

    Very good, could ve been great.This rather exhaustive review of the study of planetary magnetism is scholarly and worth reading It contains just over 20% tables definitions and cast of characters lists, that are largely unneeded The author does athan adequate job of describing and introducing all elements within the text For me it is just fluff used to plump up the book to arespectable size The author s passion for the subject is very apparent but is in some ways given less impac Very good, could ve been great.This rather exhaustive review of the study of planetary magnetism is scholarly and worth reading It contains just over 20% tables definitions and cast of characters lists, that are largely unneeded The author does athan adequate job of describing and introducing all elements within the text For me it is just fluff used to plump up the book to arespectable size The author s passion for the subject is very apparent but is in some ways given less impact than a different editor may have been able to draw out The subject is interesting, the science still somewhat incomplete, the scientists involved are complicated characters in their own rights.I paid full retail for this book and feel well compensated for my toils to earn the opportunity to read it I have and will recommend this book to many curious friends and acquaintances


  7. Susan Susan says:

    The subtitle Epic Quest misled me to expectadventure and less mathematics I found some of the chapters difficult to comprehend as a general science reader The part I enjoyed most was about the early scientists and the beginnings of the Royal Society of London in 1660 There are excellent illustrations throughout, which helped with some of the concepts that were new to me.

    I wish I wrote this Fantastic insightful rewarding accurate description of a fundamental part of life on earth It illustrates the life and importance of science like no other book.

    Mostly had to lower stars because I did not understand so much of the physics and stuff I was hoping for a little bit less academic and a littlepopular science I really enjoyed the historical side of it.

    This book was interesting but at times became a little overly technical at times I had a difficult time keeping straight the difference between inclination and declination for example.
