I knew many individual pieces of the story of how the Higgs particle was discovered, but when I read this book I found that I didn t understand the overall picture nearly as well as I d thought I did Baggott does a very good job of tying it all together and showing you how a major scientific theory grows from a crazy idea you can t even get published into something that makes front page news when it s empirically validated He seems to know the science well he s written a couple of other books on quantum mechanics and he s clearly read a lot of background and talked to many of the people involved There are some excellent anecdotes The Manhattan project ran out of copper for the powerful electromagnets, and they had to borrow 15,000 tons of silver from the US Treasury the standard metaphor for how the Higgs field works was the result of a challenge from then Cabinet Minister William Waldegrave to describe it on one sheet of paper It s interesting to see that the plot becomes easier and easier to follow as it progresses once they ve got up to running the actual experiments and crunching the numbers, it all appears very clear, and he gives a convincing explanation of how it was possible to extract an unambiguous signal from such a huge amount of noise The raw data contained billions of interaction events only a few dozen were relevant to demonstrating the existence of the Higgs But going backwards towards the beginnings, it still seems mysterious to me Three or four times, there is magic with representations of symmetry groups and renormalization, and somehow a new concept of the physical world emerges I don t think it s Baggott s fault I ve seen several other people try to explain it in non mathematical terms, and it doesn t seem to be possible.The moral is painfully obvious I need to read real quantum mechanics.

Whenever someone famous dies or there s a major royal event you will see a book arrive in the shops with undue haste It s hard to imagine it wasn t thrown together with minimum effort and with equally minimal quality So when I saw that Jim Baggott had produced a book on the Higgs boson all of five weeks after the likely detection was announced following several years work by the Large Hadron Collider at CERN, it seemed likely that this too was a botched rush job But the reality is very different.In one sense it has to be a rushed job the announcement was made on 4 July 2012 and the book was out by mid August, featuring said announcement So that bit of the book could hardly have had much time for careful editing, bearing in mind publishers usually take at least a couple of months from final versions of the text to having a physical book Much of the rest of the book was written well in advance But the remarkable trick that Baggott and OUP have pulled off is that the rush doesn t show This is an excellent book throughout.The first, but probably not most important way it s great is that it provides by far the best explanation of what the Higgs field is and how it is thought to work and what the Higgs boson has to do with anything I ve seen and that by a long margin However, for me it s not so much that, as the way it provides a superb introduction to the development of the standard model of particle physics, our current best guess of what everything s made of Again, this is the best I ve ever read and yet it s here just as a setting for the Higgs business It is really well done, and the book deserves a wide readership for that alone, not to mention the way it puts the Higgs into context.Is it perfect Well, no Like every other book I ve read on the subject it falls down on making the linkage between the mathematics of symmetry and the particle physics comprehensible That is immensely difficult to do, but ought to be possible However, as long as you take some of the symmetry stuff on trust, the rest works superbly well.Congratulations, then, to author and publisher alike Both in its timing and its content this is a tour de force Recommended.Review first published on www.popularscience.co.uk and reproduced with permission. My brain hurts after thinking so much and so hard while reading this Nevertheless I really enjoyed this book and almost cried at the end when they finally announced that it had been spotted.

w w CERNie czy Fermilabie Zdecydowanie polecam WARNING My opinion of Higgs The Invention and Discovery of the God Particle by Jim Baggott is based on the sample of the book, which includes Prologue Form and Substance , as well as on an executive summary I found newbooksinbrief.wordpress.com.What I wanted from this book is a real explanation of what the Higgs field is and how the so called massless particles interact with it and acquire mass In order to make up my mind whether to buy this book or not, I decided to taste it first I ve just finished reading both the summary and Kindle book sample.Both the sample and the summary of the book contain numerous physics concepts which I do not understand and it seems to me they are not well explained Though I m not a physicist, I ve noticed lots of misleading things, logical fallacies and inconsistencies and my impression is that this book would fail to meet my expectations.Among other things, the concepts of mass and energy are wrongly interpreted and misleadingly used throughout the book, which makes the explanation of the subject matter highly confusing.For instance, the first logical fallacy I came accross is Baggott s description of mass in the very Prologue loc 227 , which reads Mass, we now believe, is not an inherent property or primary quality of the ultimate building blocks of nature In fact, there is no such thing as mass Mass is constructed entirely from the energy of interactions involving naturally massless elementary particles I can t help but wonder what the author wants to say with such description A particle without mass does not exist Besides, if there is no mass, there is no energy, i.e capacity for performing any kind of interaction work If there s no such thing as mass, then I do not exist, and therefore I cannot buy and read the Baggott s book.In Part I, Section 4 of the summary, entitled A New Understanding of Matter , I learn that, as Baggott explains, the famous E mc squared had it that mass is fully interchangeable with energy and that therefore, mass is but another form of energy This interpretation of Einsein s equation is totally wrong The equation doesn t read E m but E mc squared, which makes a huge difference In addition, if I have no mass as Baggott s interpretation of the equation implies , how can I have energy, i.e capacity to perform any work, including buying and reading this book And now comes the best An explanation how the so called massless particle can acquire mass Quote from the summary According to the theory, the Higgs field interacts with particles and slows them down in the process loc 1178 This makes it appear as though the particle has mass in itself, but truly it only acquires its mass through the nature of the interaction The degree to which the Higgs field slows down any given particle and therefore, the mass that that particle acquires depends on the degree to which that particle interacts with the field So, it appears that non existant massless particles acquire mass because a charged field the existence of which is to be confirmed by the Higgs bosone discovery slows them down What produces that charged field Massless particles How can massless particles have energy to produce anything These questions are giving me a headache and I don t like books which give me a headache.Baggott further explains the process thus our instinct is to equate inertial mass with the amount of substance that the object possesses The stuff it contains, the harder it is to accelerate The Higgs mechanism turns this logic on its head We now interpret the extent to which the particle s acceleration is resisted by the Higgs field as the particle s inertial mass The concept of mass has vanished in a puff of logic It has been replaced by interactions between otherwise massless particles and the Higgs field loc 1189.What logic does the Higgs mechanism turn on its head What s a puff of logic in which the concept of mass has vanished Perhaps that puff of logic is a sudden confession that the terms massless and energy are wrongly and misleadingly used throughout the book My puff of logic is telling me again not to buy this book.On the other hand, it appears that this book contains a good historic review of attempts to discern a whole zoo of particles, some of which bosons are not considered as actual particles but carriers of force, and some of which fermions are considered as actual matter particles For this reason I give this book 2 stars, which means Ah, well, it s OK To laypersons who want to read this book in spite of its faults, I highly, highly recommend first to read Felix Alba Juez s book E mc 2 The Most Famous Equation in History and its Folklore Relativity free of Folkore 1 , at least Link E mc 2

recently, news out of the European Organization for Nuclear Research CERN regarding the progress of the new Large Hadron Collider LHC had been slow in coming, and nary a major discovery had been announced On July 4th, though, all of that changed As on that day CERN announced the discovery of nothing less than the Higgs boson, the God particle.The potential discovery of the Higgs boson had been one of the principal reasons why physicists were so excited about the LHC and therefore, within the scientific community the announcement was cause for a major celebration indeed For most of the general public, however, while the announcement was certainly intriguing, there were many basic questions yet to be answered Just what was the Higgs boson, and why had it been labeled the God particle Why were physicists expecting to find it, and what did the discovery really mean Adequately answering these questions was than what journalists were able to do in their compressed news segments and newspaper articles and, besides this, it was a task that many journalists were not up to regardless.Jim Baggott s new book Higgs The Invention and Discovery of the God Particle is meant to remedy this situation and provide the necessary context that the general public needs in order to understand the discovery of the Higgs boson and what it all means.With impressive clarity, Baggott first takes us through the history of the development of the Standard Model of particle physics which theory the Higgs boson is a part He begins with the discovery that atoms are made up of the still elementary particles of electrons, protons and neutrons And then takes us through the discovery of the still fundamental particles of quarks, leptons and bosons, and the 4 fundamental forces that govern these particles gravity, the electromagnetic force, the weak nuclear force, and the strong nuclear force.At every step of the way, Baggott is sure to explain what difficulties confronted the understanding of particle physics that was current at the time, what theoretical models were developed to overcome these difficulties, and the empirical evidence that was used to establish which theoretical model won the day For instance, and of crucial importance here, is that after learning of the 3 types of elementary particles, and the 4 basic forces we learn that there was a problem with the then current theory regarding the masses of the elementary particles in that the 4 forces alone were simply unable to account for it In order to overcome this difficulty, some physicists postulated that there must be a charged field pervading space, since such a field appeared to be the only appealing way to solve the mass mystery This field was called the Higgs field.The problem was that there was as yet no empirical evidence that the Higgs field actually exists What physicists did think, though, was that if it did exist, it would imply the existence of a certain type of boson particle, dubbed the Higgs boson What this meant is that if physicists could find the Higgs boson, they would have empirical evidence that the Higgs field does in fact exist, and the problem regarding the masses of elementary particles would be adequately solved On July 4th, it was the discovery of this very particle that was announced, and Baggott takes us behind the scenes at the LHC to explain just what went into the discovery.While the discovery of the Higgs boson solved one major problem with the Standard Model, there are a few others that have yet to be solved including the hierarchy problem, and the problem of explaining gravity and Baggott does touch on these issues as well.Amazing science, wonderfully told A full executive summary of the book is available here podcast discussion of the book will be available soon. Jim Baggott once wrote a lovely book about The Meaning of Quantum Theory from Planck all the way to Bell in which he said that you can t understand the physics without the philosophy That was true of the early twentieth century and its physicist philosophers Bohr, Einstein, Heisenberg, Schr dinger who laid the foundations of modern physics In this blow by blow account of the standard model and the search for the Higgs, we see how the second half of the twentieth century saw the rise of a different kind of non philosophical physicist, the brilliant mechanics who developed quantum theory into the most successful physical theory ever developed, crowned now by the discovery of the Higgs I had questions that I suppose have not been answered yet, such as what happened to Einstein s famous principle of equivalence between gravitation and inertia Inertia is due to the Higgs field and the force carrying boson, but gravitation awaits the discovery of a totally different hypothesized particle the graviton So are they not the same after all It sometimes seems that a search for all of these nuts and bolts in the erector set has replaced the elegant philosophical scientific questionings of an Einstein or Heisenberg.
