Publisher's Summary

Number One New York Times Best Seller 

The epic story of the greatest quest in all of science - the holy grail of physics that would explain the creation of the universe - from renowned theoretical physicist and author of The Future of the Mind and The Future of Humanity

When Newton discovered the law of gravity, he unified the rules governing the heavens and the Earth. Since then, physicists have been placing new forces into ever-grander theories.

But perhaps the ultimate challenge is achieving a monumental synthesis of the two remaining theories - relativity and the quantum theory. This would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science: What happened before the Big Bang? What lies on the other side of a black hole? Are there other universes and dimensions? Is time travel possible? Why are we here?

Kaku also explains the intense controversy swirling around this theory, with Nobel laureates taking opposite sides on this vital question. It is a captivating, gripping story; what’s at stake is nothing less than our conception of the universe.

Written with Kaku’s trademark enthusiasm and clarity, this epic and engaging journey is the story of The God Equation.

What the critics say

A Smithsonian Best Science Book of the Year

“This is an excellent book written by a masterful science communicator.... If there is anyone who can demystify the esoteric mathematics and physics of string theory, it is [Kaku]. And in this wonderful little book, that is precisely what he does - explain in clear and simple terms the conceptual breakthroughs, the blind alleys and the unanswered questions - in the search for a grand unified theory of everything.... The God Equation dazzles.... Kaku, a consummate storyteller, provides an engaging, unvarnished account.... His book presents cutting-edge ideas in theoretical physics, and primes readers to be ready when the next major breakthrough occurs.” (The Wall Street Journal

"Authoritative and accessible." (Nature)  

“Kaku eloquently reviews the structure of our universe, highlighting contributions from intellectual giants and those continuing the daunting, decades-long quest for the elusive theory of everything.... Examining this tantalizing theory, Kaku outlines its promises, problems, and the breathtaking, almost inconceivable array of possibilities it presents. Kaku's latest captures the awesome and mysterious beauty of the universe, of our planet, and of ourselves, and will intrigue anyone who ponders existence.” (Booklist)

Theory of Everything

No need for a personal god if you have a theory of everything and theoretically we seem close but technologically we have a long ways to go to test that beautiful theory.

One equation, one theory for all of physics but what’s God got to do with it? What is this obsession with a god? Einstein said God does not play dice, Higg’s God particle and now Michio Kaku’s “The God Equation.” Good book though, It supports superstring theory. He uses no mathematics to explain the physics of string theory, which is a very mathematical concept and he does a great job at it. His explanations are clear and simple presenting the theory of everything.

Before he died Einstein was looking for a unified field theory. Michio Kaku thinks String theory is the answer as do many other physicists though he does mention that there is currently no testable evidence. He leaves it open and asks if string theory is an answer to everything or perhaps to nothing.

It’s an easy to read book which asks the ultimate question as he goes through the historical search for it and ties mathematical rules to it discussing relativity with a clear description of the light speed conundrum tying relativity to the beginnings of unification.

Beauty is symmetry.

He goes on through the rise of the quantum by bringing us through chemistry and the rise of the periodic table then moving on to the dual slit experiment but also tying quantum physics with our current technologies and even biology. The book goes on to tie field theory with particle theory (leaning towards string).
Mentioning the ad hoc way that the standard model was put together, notwithstanding that it is accurate for what it describes, but notes it doesn’t cover everything.

Pay attention to the discussion of the graviton and the problem of integrating it with the standard model, infinities occur. That and black holes and the conflict of theory of gravity and the quantum theory and the next great revolution, string theory.

Interesting, something new for me, https://www.ima.umn.edu/sites/default/files/691.pdf, Euler’s scattering equation for evolution of flow in an ideal fluid matches the scattering of two subatomic particles. The beginning of string theory. I did not know what was the seed of it.

Talks about how string field theory and how gravity can be married to particle theory’s standard model then goes on to explain Calabi yau space and its place in string theory.

Chapter 6 ‘Promise and Problems’ requires your undivided attention.

Not what you may think

In sum: At best, this book is a historical overview of select milestones in physics. Overall, it is a good starting point for beginners in this effort, but is dense enough to evade their understanding of the themes. This book is NOT, on the other hand, a user friendly overview of modern physics that a layman can read and change their view of the universe. I am regretful of starting this book thinking it was the latter.

At its heart, this is a book about string theory (super string theory), but the book fails to describe string theory, distinguish it from super string theory, and provide tangible description of how this mathematical model structures the world around us. At the end of listening, I both feel like I learned something (maybe insight into Einstein the person) and am somehow unable to articulate any new information about physics.

At worst, this book reads like a PowerPoint lecture. Perhaps even worse (and I’m not usually the guy who makes this point), Kaku seems to deftly avoid mentioning any women or their contribution to the field. Names like Vera Rubin (who spent 20 years developing ideas that resulted in the concept of Dark Matter) or Katie Bouman (who was made famous as the first person to see the first image of a black hole) are not found here. He mentions Curie and Roslyn Franklin (for some reason, though she was not a physicist!), but this book smacks of a male-centric, ivory tower view of physics. Any book is just the view of its author, I suppose, but this reaaaally just feels like the views of one, out-of-touch scientist.

Overall, I can’t recommend this for almost anyone with any level of physics background.

kinda irrelevant...

If you've read his other great works then this will feel like an irrelevant publish. basically just a simple explanation of how we got somewhat to the scientific explanation of everything, that still can't be confirmed. So nothing new or ground breaking really. Makes me glad it was so short.

Inspirational for good scifi and education.

The excellent combination of scientific information with futuristc possibility based on solid science, makes this book worth several readings, givin new insights everytime.
for those who write scifi, this book is a great source for story plots based on excellent science.

Nice Historic Explanation of Physics

The book provides a historic explanation of physics and how we got to where we are now as well as a look at where physics is headed.

Ok

The God Equation

This book would be ok for someone new to the ideas and concepts. If one has read his other books or has read books from others in similar fields, there's nothing new here.

Great for anyone, but excellent for educators (and students) of STEM

Great mix of science, math, technology, and philosophy. Very applicable to the modern day and the technological advancements that are anticipated with the 4th industrial revolution. I teach high school AP chemistry and after the test we study quantum mechanics from two perspectives: science and also philosophy. If my school budget can afford it- I’d love to buy a classroom set of this book for students (or maybe the author might hook us up with this stellar review! Signed of course).

less substantive than I expected

Interesting overview, but less substantive than I was hoping for. Not worth a full credit.

This was an awesome read and it left me with a feeling wonderment without feeling wholly satisfied. Believe it or not, I thoroughly enjoyed reading it.

The God Equation

An excellent overview of scientific theories about the universe. I am not a scientist but I learned a lot about what we do know and perhaps more important what we don’t know.
It discusses modern science from Newton to string theory in a succinct and clear way. I would highly recommend it.

Novice

This was an interesting book and good for an inquisitive mind, basic enough for a novice to grasp!
