Fear of Physics: A Guide for the Perplexed by Lawrence M. Krauss (EPUB)

Description

Assume the cow is a sphere. So begins this lively, irreverent, and informative look at everything from the physics of boiling water to cutting-edge research at the observable limits of the universe. Rich with anecdotes and accessible examples, Fear of Physics nimbly ranges over the tools and thought behind the world of modern physics, taking the mystery out of what is essentially a very human intellectual endeavour.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐I assign chapters from this book to my physics students along with Lewin’s book, For the Love of Physics. Both change their viewpoint of physics and physicists. Students often have the misconception that all science is done by boring white men with crazy hair who hang out in labs following some set of directions and discovering new ideas in an orderly fashion. Teaching them to see science as messy, somewhat random and also exciting and bewildering is part of my mission in educating them.These two books do not help with the “white guy” perception (and sorry, not much with the crazy hair stereotype), but at least the students begin to see science as a living, breathing entity, rather than a bunch of math (with the most important formulas boxed up or presented in bold type) from a typical physics text. Frankly, most of them are not going to remember even the basic physics formulas a decade from now, but they will remember the topics from this book. If they can hold onto excitement which Krauss expresses in his book (you will NEVER read a better explanation of why we need scientific notation) I consider my job as well done.I am finally getting around to writing this review after years of assigning the book because my son had the chance to take a class with Krauss at ASU, which he adored. I waited until the grades were assigned to upload this review, finally getting this done is a small way of paying back for the joy of physics he has given indirectly to my students, and directly to my son. I also hope to do a small part in making physics a topic which does not induce cringing, but delight, and this book helps me to do so for my students.

⭐I’m a big fan of Krauss, and this is one of his better books. Physics isn’t for sissies, and you have to put some effort into reading this, even if it is pretty dumbed-down stuff. If you can get through it and understand 80% of what he is writing, you will be ahead of 95% of your friends. Not written for the person with zero background, nor for the scientist, but those of us in the middle who know a little and want to know more.

⭐The book shop is wonderful, as well as the mail service. Shipped very fast and the book arrived in a good status, didn’t get any damage (shipped to China). It’s an excellent book – perfect content, beautiful printing. Everything is satisfying. Thank you very much for everything.

⭐The writer here has the knack of holding the reader to a subject that to say the very least is somewhat complex….ha!As technology receives the tools to further search into the vitals of that strange world of micro bio-physics and at the same time goes deeper and deeper into ‘space’ exploration here we have laid out before us the two set side by side.It was never going to be easy for the general reader to keep-up-with-the-play but nice to see the attemptRay HF

⭐Fear of Physics is a more intricate read than most popular science books, which could confuse certain readers whose scientific literacy is not that developped. However, for those that have a sturdier knowledge on the topic, this book is a fascinating read and a great addition to ones understanding on the mysteries of physics; from a non-scientist perspective. Lawrence Krauss lands a few enlightening points, with a a big emphasis on the ubiquity of symmetry. With his fantastic penmanship the reader will get a deeper glimpse into the workings of physics.

⭐A surprisingly nuanced yet accessible look at modern physics. Krauss starts out at a welcome, remedial pace — walking the reader through basic tenets of physics and mathematics. However, by the end of the book, Krauss has equipped the lay reader (like myself) to finally understand bleeding-edge concepts of physics like renormalization and symmetry-breaking. This book is for the enthusiastic learner, not the faint of heart.

⭐Although interesting Krauss assumes you have some background in the subject. Not a really a humorous approach but practical.

⭐This is a great book. However it wasn’t much new for me. It’s the type of book you’d want to read after a book like Physics for Dummies. It’s well written and simple to understand, with humor.

⭐In Fear of Physics, Lawrence Krauss sets out to explain how physicists think about the universe and how, by applying just a few fundamental principles, they are able to tackle new problems in pursuit of a deeper understanding. Adopting a structured approach, Krauss covers the processes (simplifying complex problems, orders of magnitude, etc.), progress (building on the existing body of knowledge and the connections between apparently disparate phenomena), and principles (specifically, scaling and symmetry) that contribute to the advance of theoretical physics. In the final chapter, he also allows himself the indulgence of speculating on the likelihood and desirability of a Theory of Everything.The book serves as a useful description of how scientists probe the complex and often hidden connections between existing scientific theories for new insights and illustrates how they (and, just as importantly, we) can be confident in their findings, even if at times, the results can be palpably counter-intuitive. This is a fascinating and worthwhile read that demonstrates clearly how the current theoretical ideas are on a secure intellectual footing: moreover, Krauss’ easygoing style and a gentle humour is as engaging as it is illuminating and anybody with an interest in the scientific process will surely enjoy this book.Nonetheless, one cannot explain how physicists think without first describing what it is that they think about and it is here that Krauss seems to flounder. Whilst this book is more about physicists than it is about physics, a grasp of concepts such as relativity and symmetry are prerequisites to understanding the current direction of scientific research and, compared to other contemporary authors, some of Krauss’ explanations of these ideas can seem clumsy and superficial. The result is a book that feels half-finished (or perhaps, twice as long as necessary) and thus, less than satisfying.Notwithstanding these reservations, Krauss’ spherical cow and perpetual motion machine are wonderful devices for describing how physicists adopt a pragmatic approach to novel ideas and explaining rule of thumb concepts: in fact, they are so good that they are probably worth the cover price alone. Moreover, most people considering this book will already be grounded in some of the more arcane ideas of modern physics, which, to some extent, should mitigate these limitations.In summary, if you are seeking insight into how physicists go about their day jobs, you will doubtless find this text both enjoyable and informative. However, if you are looking for an introductory text in theoretical physics, there are titles that are, perhaps, more appropriate.

⭐Lawrence Krauss is an excellent writer. I thoroughly recommend this book to anyone with a passing interest in cosmology and the physics of the universe. This book might appear at first glance to be aimed at those readers that want only a very broad summary of physics, however Lawrence takes the reader through a tour of how physics has evolved over the last few hundred years to show how some key fundamental ideas (such as symmetry) now guide the whole of our current understanding of how the physical universe works. An excellent book.

⭐Fear of Physics? Read this and you won’t have. Krauss’s sense of humour matches mine. I knew a fair bit of what is presented, but it is amusing, very easy to read and provided further insight.Whether you have fear of or enthusiasm for Physics, this is a darn good read.

⭐Excellent book if a bit long winded, but then I find reading difficult anyway.

⭐Amenísimo libro sobre Física, en versión original en Inglés. El profesor Krauss es un excelente comunicador. Nada que no supiéramos ya.
