The God Equation: The Quest for a Theory of Everything

This was a excellent book. I find the title to be somewhat misleading, but it does fit. The book goes through the history of physics and all of the mathematical discoveries that have lead to string theory and how they all fit together. It is very fascinating to learn the history of all of physics and how all of the pieces of the puzzle fit together by some of the greatest physicists. The author also talks about how it cannot be proven and is not definitive, but mathematically it is the best solution we currently have. Very good book.

Spiritual seekers try to find and understand the mind of god. Some physicists are trying to incorporate it into equations. Michio Kaku is that rare scientist that is capable of explaining things to simpletons like me the concepts and progress of modern research into the meaning of life. While most of use have heard of Einstein's theory of relativity, a majority cannot fathom the intricacies of general relativity and special relativity. Those who can wade through Einstein's famous theories sometime come across the Dirac Equation and Heisenberg's Uncertainty Principle. In this book, Professor Kaku guides us through the breakthroughs in understanding the universe starting with Newton and Galileo. After reading and rereading the book, I found myself reeling as I tried to comprehend Maxwell's equations and the oft-mentioned string theory and the possibility that we live in eleven dimensions. That being said, any intelligent person curious about reality and the meaning of life will benefit from reading The God Equation. Even if you become lost and disoriented, you will be blessed by reading chapter 7. This is a wonderful book for seekers of truth.

concisely written and informative. though it does take a detour in the last couple of pages into the author's views on religion/spirituality in a way that seems out of place and unnecessary.

I have read a number of books on physics and Michio Kaku should win a Nobel for his communication skills. That being said, since Einstein theories, physics has turned into a game where scientists have turned into gossips. A gossip is a person who takes an idea or hypothesis without a provable truth and treats the hypothesis as truth. The they build out a complete theory based on this very shaky foundation and find some semi truths that can actually do work but will never find the complete truth because the foundation is built on sand. Physics will drift from here because students accept these semi truths and try to build even further. The old generation who controls physics will have to dye off and everything they have built will have to be torn down leaving only the provable facts and then start over again. Even today physicists speak of gravity as a pulling force of matter to matter. They even think they see virtual particles from a man made vacuum ignoring the idea that their vacuum is filled with dark matter, neutrinos and space localities that are gravity itself. I've read many books on physics and Michio's book is the first to even mention that gravity is not mass pulling on mass. This book is the best book on the current state of physics notwithstanding my objections to quantum physics huge problems. I'm just sad that I'm too old to see what will become of the new theories once the old has been torn down and a new perspective is taken inclusive of the few provable facts left behind.

The author did a fabulous job (he thanks his editor and others) writing the history of physics -- I take this to be a introductory course for the non-physics major BUT it would serve as a very good introduction to all of physics and a breakdown of material the physics major would be studying. The historical line makes it more understandable with names, dates and achievements and failures. Don't miss the NOTES at the end of his book which goes a bit deeper in some of the material. Well worth the money!

Just a group of pages left, I love Kaku’s books, this is my 3rd plus one other delivered today

This is my absolute favorite book! Not only does world renowned physicist Michio Kaku mention what the purpose of the God Equation is but also how we can get there and what human kind has already done. This book gives me hope that we will find the solution at some point. This is also fairly easy to read if you don’t understand the topic that well. Totally recommend!

I've read many books for the math-challenged but well-educated reader who is very interested in quantum theory and cosmology. This one has a compelling title, a seductive cover and an author with a stellar reputation in string theory and quantum physics, but who falls short in his writing (at least for the lay reader). The book often It reads as if it were self-published and (poorly) self-edited. Much of the wording is frustrating, omitting logical bridges (when they exist) between analogy and fact, and distracting from both factual material and reading flow. There are some fine comments and concepts, and nice quotes (some poorly illustrative, I think) from other current and past luminaries, but the writing, like that of many scientists, elite thinkers and medical scholars, really needs professional editing in order to bridge the "comprehension gap" effectively and engage the (educated) layperson. The author thanks his editor, but IMO, whoever edited this book did a poor job. (BTW, Prof. Kaku has a long list of wonderful accomplishments, making it unfortunate that chose to include sensationalized quasi-science cable TV shows among them. I wish I understood the language of higher mathematics and could understant things like 10- and 11-dimension environments, but alas I must rely on geniuses who can dumb it down but retain accuracy. There is a small handful of physicists who do that well, but Professor Maku does not appear, from this book anyway, to be as good at that as I hoped.

As someone who has a 'passing' knowledge and understanding of physics, mainly through watching programmes such as Horizon etc, I found this to be well written for someone like me to understand. I have always enjoyed watching programmes presented by Michio Kaku. He has the ability to explain some pretty mind boggling physics, in a way that even I can grasp. This book is no exception. He leads you on a journey, laying out explantions of theories in a manageable form. On occasion, I did have to re-read a few pages to fully grasp some areas, but given the subject I didn't find it daunting and it did give the brain a good shake-out. :-)

I'm not a physicist and before reading this book I had only a small amount of knowledge about physics. This book blew my mind ( I have to admit that a couple of times I had to read parts of it twice) I also knew the author Michio Kaku, by seeing him in documentaries and interviews, in this book he does an amazing job to help me a layperson to understand and excited about the subject matter, he does an incredible job in getting the attention of the reader, while lighting our curiosity to keep reading. The subject matter in the hands of someone else could have easily snuff out my curiosity, but Michio Kaku kept my eyes on the page and my imagination and my desire to learn more, expanding like a black hole in space

東日本大震災の時にカク教授を知りました。米国のABCを見ると、原発事故の解説者でした。名前と顔付から日系人と分かり信頼したのですが、教授は「間違いなくメルトダウン（炉心溶融）が発生」と発言。慌ててNHK,朝日新聞等を読んだのですが、溶融には一切ふれてません。顔は日系人だが、心は米国人、大げさな事を言う人だなと思いました。処が一年後、日本メディアは政府発表としてメルトダウンは発生していたと報道開始。カク教授が正しかった事を知り、日本メディアは今でも大本営発表を無責任に報道してる事を再確認し、新聞の購読を止めました。 閑話休題：本書の前半はギリシャから始まり、ガリレオの天体観測、ケプラーの法則、そしてニュートンの万有引力の発見と続き、電場、磁場を統一したマックスウェルの電磁波理論へと進む。アインシュタインが登場し、彼は思考実験に集中し「時間とスペース」「物体とエネルギー」をシンメトリー的に捉え、ニュートン力学の誤差を修正した光速度でも正しく宇宙全体の動きをとらえる一般相対性理論を完成させる。その後、アインシュタインは重力場と電磁気場を統合した統一場理論（Unified Filed Theory：The God Theoryの原型)を完成さようとするも思考実験が上手くいかず、数式をいじくりまわし後半生を無為に生きる。時を前後して発展したのが、宇宙とは真逆の方向：物体の最小単位とその動きを知る量子力学。その根幹をなすのが電子などの量子の運動を捉えたシュレーディンガー波動方程式。やがて、フォアマン、朝永博士などにより、荷電量子間の電磁作用を量子的に記述する量子電磁力学が台頭するが矛盾点（計算結果が無限大に発散する等）も多く行き詰まりを感じてきた1968年に、弦理論が発表される。ここで話題を少し変え、相対性理論で証明され、宇宙観測の結果として信実として確定された事項を記述する：宇宙と宇宙エネルギーは無限大、宇宙には起源が有り、ビッグバンは138億年前に発生、宇宙は膨張しており、ダークホールは存在する。注意するのは一部の科学者が記述する真実とは証明されてない推測の存在：タイムトラベル、ダークホールの向こう側、ウォームホール、ダークマター、ダークエネルギー等です。これらの多くは「存在しないのが証明されてないので、宇宙のどこかに存在する」との詭弁が使用されあたかも事実として記述してる書物も多い。弦理論は18世紀ガウスと並び称される数学・天体学者：レオンハルト・オイラーが発表した数学理論で、日米の量子力学者が二つのサブアトミック粒子の動きを弦理論で解明した事で知られる。本来の物理理論は現象・実験から成り立ちが弦理論は逆に現存する数学理論に物理現象を当てはめている。カク教授も博士論文で弦理論を駆使し先駆者の一人である。ただ本書で彼は、弦理論の限界を述べている。一つは「実験と観測が出来ない事」。例えばダークホールに向かう物質を弦理論に適用すると、「物質はダークホールを付き抜き反対側の異次元空間へと行く」。この現象は現時点では観測・実験共不可能です。他には弦理論そのものが年代共に発展し、新しい理論（超弦理論）は古い理論を否定し、現在主流の超弦理論もやがて新弦理論に置き換わられる。カク教授は「自分が生きているまでには最終理論を知りたい」と、意味深な言葉を残している。 結論：評者の結論は大天才アインシュタインですら重力場と電磁場を統合する理論を構築できなかったのに、並のノーベル物理学者が何人も集まって数式をいじくり廻しても、重力場・電磁場・弱い力・強い力（共に量子間の場）を統合するThe God Equationを完成させるのは極めて難しい。ケプラー、ニュートン、アインシュタイン等をはるかに超える超天才の出現を待つばかりでしょう。ギリシャから現代までの物理の総まとめと、現在の課題が明確に記述された名著です。さすがカク教授、一読の価値が大。

En gran libro de divulgación que abre la tu curiosidad a conocer más.
