Physics of The Impossible

Book For Physics Students Who Love Science-Fiction!

book review of physics of the impossible by michio kaku best physics books

Do you happen to be a Doctor Who or Star Trek fan? Have you ever wondered how time travel or teleportation or invisibility could become a reality well within the laws of physics? If yes, then this book is a must for you, no kidding!

The guiding philosophy of this book is this: If, in principle, it is possible, then it may be achieved! Various futuristic technologies have been divided into different classes of impossibilities...Meaning how unlikely they are going to be.


  • Class I Impossibilities are "technologies that are impossible today, but that do not violate the known laws of physics."
  • Class II Impossibilities are “technologies that sit at the very edge of our understanding of the physical world."
  • Class III Impossibilities are “technologies that violate the known laws of physics but their development would represent a crucial shift in our understanding of physics!"

The author is renowned American theoretical physicist Michio Kaku known for his contributions to the string field theory. The book is primarily aimed for aspiring physicists, that is, undergraduate and graduate students; but engineers will also enjoy it!

Why did Kaku decide to write a whole 350-pages book in order to predict the technology of tomorrow? Because, he strongly believes that, what's impossible today, might become pretty common tomorrow.

For example, William Thomson Kelvin, a mathematical physicist and creator of the Kelvin scale had declared that “heavier than air” flying machines would be impossible.

Similarly, Ernest Rutherford, a physicist who experimentally described the atom, thought the atom bomb was impossible and he compared it to moonshine (a crazy or foolish idea).


Such technologies were considered impossible because the basic laws of physics and science were not understood as well as they'd subsequently be.

Kaku has shown in the book, with numerous examples, how scientists and technicians around the world are trying to realize tomorrow...today...in their own individual laboratories.

There's a whole lot of physics in it as well...such as the description of LASER and how it works. Histories of telepathy and artificial intelligence have been narrated in a manner which do not sound boring.

As you unravel the secrets of them alien technologies (which you can see only on TV shows), you will begin to feel a sense of fulfillment...more like a feeling of accomplishment!

That we're headed on the right track; this book will surely renew your confidence in the possibilities of physics. To be honest, the phrase, "one of a kind" was probably invented for such a book because this is a book unlike any other!
