The Universe in a Nutshell by Stephen Hawking introduces you to the frontiers of theoretical physics, right in the light where reality is far more bizarre and wonderful than fantasy.
Hawking, like many other scientists, sought a theory in this field that could explain and interpret all the events of this vast world.
He combines Einstein’s theory of general relativity with Richard Feynman’s theory of multiple histories, and presents them as a unified theory called Theory-M.
Hawking takes you on an exciting journey through space-time and talks about strings, particles, probes, time travel and the eleventh dimension.
In The Universe in a Nutshell, you will learn the mysteries of black holes and the origin of the world, and put the pieces of the universe together.
About the Author: Stephen Hawking
Stephen Hawking was an English physicist, cosmologist, and author, and director of research at the Center for Theoretical Cosmology at the University of Cambridge, born January 8, 1942 in England.
He was a regular member of the Society of Bishops of Science and received the Presidential Medal of Freedom in 2009.
From 1979 to 2009, he held the Lucas Chair in Mathematics for thirty years. He was best known for his cosmology and quantum gravity, especially for black holes. His most famous book, History of Time, which was the best-selling book in Britain for 237 weeks, made him even more famous.
Hawking’s other book, The Big Plan, released in 2010, quickly became one of Amazon’s best-selling books.
He had amyotrophic lateral sclerosis and had no movement, was unable to sit or walk or stand.
He could not even move his arms and legs, or bend his body, or speak. He finally died in 2018 at the age of 76 at his home.
In a part of the book The World in Walnut Peel, we read:
Einstein’s theory of general relativity transformed time and space from a passive background in which events take place to an active actor in the mechanisms of the universe.
This led to a major problem that remains at the forefront of physics problems in the 21st century. The universe is full of matter, and matter swings space so much that objects fall on each other.
Einstein found that his equations had no answer to describe a static world that did not change over time.
Instead of abandoning such a long-standing universe, which he and many others believed in, he manipulated equations and added a phrase called cosmological constant.
The cosmological constant swung space-time in opposite directions as objects moved away from each other.
According to the honorary correspondent of the International Quran News Agency (IQNA), this book has won the Ontis Award as the best scientific book.
The World in a Walnut Skin is a sequel to The History of Time, which includes Stephen Hawking’s latest comments on black holes, as well as Larry King’s interview with Professor Hawking. Stephen Hawking is one of the most influential thinkers of our time.
His adventurous ideas and his witty way of expressing his thoughts have made him famous.
The book History of Time, which has sold millions of copies, provides an enchanting view of theoretical physics for readers around the world.
Now, in a new book full of illustrations and diagrams, Hawking addresses the most important events that have taken place since History.
He takes us to the most advanced parts of theoretical physics. Where reality is often marvelous in imagination and simply expresses the principles that govern the world.
Professor Hawking, like many other scientists in the international scientific community, seeks the sum of knowledge, the deceptive theory of all that is hidden in the heart of the universe.
In The World in Walnut Peel, he guides us on an exploratory journey to unravel the mysteries of the universe, from supergravity to super symmetry, from quantum theory to M theory, from halogography to duality.
In this most exciting mental adventure, he seeks to combine Einstein’s theory of general relativity with Richard Feynman’s multiple-history theory, and to provide a unified stop theory that describes everything that happens in the world.
He takes us to the pristine and untouched frontiers of knowledge. Perhaps the theory of the superstring and the P-branes may be the key to unraveling this puzzle. Reading the book The World in Walnut Peel is essential for anyone who wants to know the world in which they live.
This book is written in six chapters, the topics of which include 1- A brief history of relativity 2- The shape of time 3- The world in walnut shell 4- Foretelling the future 5- Guarding the past 6- Our future? Star Trek or not? And 7- The new world is the best.
Man has always sought to discover the secrets of the world in which he lives: the touch of “the world in the shell”; Just as briefly and to the extent available.
The environment around us is familiar to us because we know it. But if we want to look at the world through a much larger lens, all we have to do is look up at the sky above us. It seems that not only the ground beneath us, but also what seems infinite and deep above us, is so great that the temptation to know and the fear of its immense vastness shakes our limbs.
This is not a modern-day temptation, and perhaps trying to know the world beyond what we feel under our feet will last a lifetime.
The natural sciences, astronomy, astronomy, physics, and, as our contemporary scientist Stephen Hawking followed, cosmology, were manifestations of human endeavors to explore the universe that make life on earth amazing and full of undiscovered but very small rules in the heart of the universe. .
Stephen Hawking talks about cosmology to the general public
Stephen Hawking is known almost to everyone.
A scientist whose research in the field of cosmology and quantum gravity has brought remarkable achievements to science, especially in the field of black holes. In addition, his harsh physical condition and even his personal life always left room for even unscientific quotes from Stephen Hawking.
Stephen Hawking was 21 years old when he realized that occasional falls on the steps of the University of Cambridge and not mastering the tying of his shoes were not due to being helpless or traveling to other worlds!
He is the most famous person to suffer from the rare disease ALS, which resulted in nothing but gradual paralysis and disability.
Of course, for someone who was skeptical of textbooks as a child and doubted everything, the belief that he would not really survive for another two or three years was questionable. Maybe the doctors are wrong too! And so it was, and he lived to be seventy-six years old, and until the end of his life he was the most famous scientist known to ordinary people today.
How is it that when we want to talk about a complex and strange subject, we liken its incomprehensibility to quantum physics, but at the same time we follow the profession of a quantum physicist and not only understand it to a great extent, but sometimes at Do we publish short sentences on social networks?
This is what Stephen Hawking had in mind since 1988 when he wrote A Brief History of Time. He wanted to explain the complexities of cosmology to ordinary people in a language as far from complex as possible without the aid of mathematical equations.
Of course, he himself did not think that the writing of this book would be so welcomed and that it would remain the best-selling book in Britain with a record of 237 weeks, which is almost five years.
The book was later followed by Stephen Hawking, who was asked to write a sequel, and in 2001, The World in a Walnut Skin was published. Of course, Hawking himself points out in the introduction that this book is not necessarily a sequel to the previous book.
The book “The World in Walnut Peel” is recommended for those who are fascinated by the world of science-fiction books, except for those who are interested in science books.
This time, not to read a new sci-fi story, but because the curiosity and excitement of exploring the world of fantasy is undoubtedly sweeter than having a background in science.
It can be guaranteed that if you are a fan of science-fiction genres, you will definitely like the world of science fiction books in simple language.
In fact, for anyone who has ever thought about time travel or from the strange discoveries of man in space and the thought of traveling by spacecraft, smoke rises from his head, the book “The world in walnut shell” will be interesting and readable.
You may also remember your last encounter with these areas in high school by choosing a career and study path far removed from mathematics and physics.
But do not forget that this book has exactly the same audience as you. Also, the Internet is with us everywhere and always these days, so wherever you have a problem, you can easily search.
It is true that when you hold the book, a series of unfamiliar words scare you from not understanding the rest of the book, but put that fear aside and treat yourself to the joy of revelation in cosmology!
In the introduction to this book, Stephen Hawking writes:
I did not want to write about the boy in “A Brief History of Time” or a slightly longer history, but I came to the conclusion that there is room for a different book with a different understanding.
The brief history book was organized in a linear manner, and most of the chapters were logical and dependent on previous chapters.
This was enjoyable for some readers, but others got stuck in the very first chapters and never got to the more exciting content of the later chapters.
In contrast, the book is more like a tree. Chapters one and two form the central trunk and the other chapters branch off from it.
The branches are more or less independent and can be dealt with after each of the central trunks.

The pictures as well as the captions in the columns next to the content are good guides that are almost everywhere in the book. One of the fascinating branches of the “walnut shell world” is related to string theory and, of course, the possibility of time travel.
In one of the feasibility studies, Hawking, assuming the existence of wormholes, says about time travel:
It takes tens of thousands of years for a galaxy to pass through a galaxy at a speed slower than the speed of light, but you may pass through a wormhole and cross the galaxy and return home for dinner.
It can be shown that if there are wormholes, you can also use them and return to your original position before starting to move. So you might think to blow up a rocket on the launch pad to prevent your departure.
This is another version of “Grandfather Contradiction.” What happens if you travel back in time and kill your grandfather before your father was born? -Part of the book-
Part of the book related to the first chapter
A very important result of relativity is the relationship between mass and energy. Albert Einstein’s claim that the speed of light should be the same for all observers requires that nothing can move faster than light.
As a result, using energy to accelerate anything, whether it is a particle or a spaceship, increases its mass and makes more work harder.
It will be impossible to accelerate a particle to the speed of light. Because it will require an infinite amount of energy. Mass and energy are equivalent.
As summarized in Einstein’s famous formula: E = MC 2 It can be said that this equation in physics is the only equation that has a special and general reputation.
Among its findings was the realization that if the nucleus of a uranium atom split and split into two nuclei with almost lower masses, it would produce enormous energy.
