Description 3. Book Details Author: Sometimes more than one of these waves can interfere with each other - the crests and the troughs line up. This is called light interference. When light waves interfere with each other, this can make many colors. An example of this is the colors in soap bubbles. Chapter 5: Elementary Particles and Forces of Nature[ edit ] Quarks and other elementary particles are the topic of this chapter.

Quarks are very small things that make up everything we see matter. There are six different "flavors" of quarks: the up quark, down quark, strange quark, charmed quark, bottom quark, and top quark. Quarks also have three "colors": red, green, and blue. There are also anti-quarks, which are the opposite of the regular quarks. In total, there are 18 different types of regular quarks, and 18 different types of anti quarks.

Quarks are known as the "building blocks of matter" because they are the smallest thing that make up all the matter in the universe. A particle of spin 1 needs to be turned around all the way to look the same again, like this arrow. All particles for example, the quarks have something called spin. The spin of a particle shows us what a particle looks like from different directions. For example, a particle of spin 0 looks the same from every direction. A particle of spin 1 looks different in every direction, unless the particle is spun completely around degrees.

Hawking's example of a particle of spin 1 is an arrow. A particle of spin two needs to be turned around halfway or degrees to look the same.

The example given in the book is of a double-headed arrow. All of these particles follow the Pauli exclusion principle. Pauli's exclusion principle says that particles cannot be in the same place or have the same speed. If Pauli's exclusion principle did not exist, then everything in the universe would look the same, like a roughly uniform and dense "soup". This is a proton. It is made up of three quarks.

All the quarks are different colors because of confinement. Particles with a spin of 0, 1, or 2 move force from one particle to another. Some examples of these particles are virtual gravitons and virtual photons. Virtual gravitons have a spin of 2 and they represent the force of gravity. This means that when gravity affects two things, gravitons move to and from the two things.

Virtual photons have a spin of 1 and represent electromagnetic forces or the force that holds atoms together. Besides the force of gravity and the electromagnetic forces, there are weak and strong nuclear forces. Weak nuclear forces are the forces that cause radioactivity , or when matter emits energy. Strong nuclear forces are the forces that keep the quarks in a neutron and a proton together, and keeps the protons and neutrons together in an atom.

The particle that carries the strong nuclear force is thought to be a gluon. The gluon is a particle with a spin of 1. The gluon holds together quarks to form protons and neutrons.

However, the gluon only holds together quarks that are three different colors. This makes the end product have no color. This is called confinement. Some scientists have tried to make a theory that combines the electromagnetic force, the weak nuclear force, and the strong nuclear force. This theory is called a grand unified theory or a GUT. This theory tries to explain these forces in one big unified way or theory. Chapter 6: Black Holes[ edit ] A picture of a black hole and how it changes light around it.

Black holes are talked about in this chapter. Black holes are stars that have collapsed into one very small point. This small point is called a singularity.

Black holes suck things into their center because they have very strong gravity. Some of the things it can suck in are light and stars. Only very large stars, called super-giants, are big enough to become a black hole. The star must be one and a half times the mass of the sun or larger to turn into a black hole. This number is called the Chandrasekhar limit. If the mass of a star is less than the Chandrasekhar limit, it will not turn into a black hole; instead, it will turn into a different, smaller type of star.

The boundary of the black hole is called the event horizon. If something is in the event horizon, it will never get out of the black hole. Black holes can be shaped differently. Some black holes are perfectly spherical - like a ball. Other black holes bulge in the middle. Black holes will be spherical if they do not rotate.

The Illustrated A Brief History of Time/The Universe in a Nutshell by Stephen Hawking

Black holes will bulge in the middle if they rotate. Black holes are difficult to find because they do not let out any light. They can be found when black holes suck in other stars. When black holes suck in other stars, the black hole lets out X-rays , which can be seen by telescopes. In this chapter, Hawking talks about his bet with another scientist, Kip Thorne. Hawking bet that black holes did not exist, because he did not want his work on black holes to be wasted.

He lost the bet. Hawking realized that the event horizon of a black hole could only get bigger, not smaller. The area of the event horizon of a black hole gets bigger whenever something falls into the black hole.

He also realized that when two black holes combine, the size of the new event horizon is greater than or equal to the sum of the event horizons of the two original black holes.

This means that a black hole's event horizon can never get smaller. Disorder, also known as entropy , is related to black holes. There is a scientific law that has to do with entropy. This law is called the second law of thermodynamics , and it says that entropy or disorder will always increase in an isolated system for example, the universe. The relation between the amount of entropy in a black hole and the size of the black hole's event horizon was first thought of by a research student Jacob Bekenstein and proven by Hawking, whose calculations said that black holes emit radiation.

This was strange, because it was already said that nothing can escape from a black hole's event horizon. This problem was solved when the idea of pairs of "virtual particles" was thought of.

One of the pair of particles would fall into the black hole, and the other would escape. This would look like the black hole was emitting particles.

This idea seemed strange at first, but many people accepted it after a while. Chapter 8: The Origin and Fate of the Universe[ edit ] The Big Bang and the evolution of the universe How the universe started and how it might end is discussed in this chapter. Most scientists agree that the universe started in an expansion called the Big Bang. The model for this is called the "hot big bang model". When the universe starts getting bigger, the things inside of it also begin to get cooler.

When the universe was first beginning, it was infinitely hot. The temperature of the universe cooled and the things inside the universe began to clump together. Hawking also discusses how the universe could have been. For example, if the universe formed and then collapsed quickly, there would not be enough time for life to form. Another example would be a universe that expanded too quickly.

If a universe expanded too quickly, it would become almost empty. It was something that always stuck with me and when I saw the opportunity There's a reason I never took physics It was something that always stuck with me and when I saw the opportunity to download an illustrated version coupled with a second book by Hawking for super cheap at my Borders' closing sale, I snatched it up. In both books, Dr. Hawking explains amazingly complex concepts in an easily comprehensible if not necessarily understandable way which seems to break things down as simply as possible.

On it's own, I would give "Brief History" 5 Stars. The book starts with a fairly clear thesis and moves step by step describing all the points it intended to hit.

And the illustrations are a nice bonus. It should be noted that this text was updated from the original version published in the late 80's. I'm not sure if it differs any from the version I read in the late 90's but there definitely seemed to be a few concepts I don't recall from the first time around. But over all, Brief History is pretty understandable, and eye opening once you can wrap your mind around the concepts involved.

Perhaps part of the problem comparing the two books is that relativity as a theory is over years old. It seems to be something that most averagely not a word I know educated people have a basic grasp up, so the elaborations in Brief History are easier to follow.

Then the book gets into string theory. Which I seem to recall understanding once upon a time. And then the second book elaborates on that, and moves from there to "branes" and ten dimensional space and imaginary time and a whole lot of much more modern theory is thrown at you all at once.

Plus, Hawking acknowledges in the prologue to "Universe in a Nutshell" that he conceived that book as one that has, more or less, stand alone chapters which refer to each other but don't build a story flow as it were.

There's a whole lot going on in that book and a lot of it, even if I read it over a few times, flew right over my head. Though a part of me feels I could really grasp everything it discusses if I push myself to struggle through a reread. And maybe in about years I'll feel up to it.

I'm keeping the book so it'll always be on the shelf. And I'll willingly admit, perhaps it's not fair to not give this book a full 5 star rating based on my own ignorance and inability to understand what seems like the easiest explanation of very complicated ideas. But as I said before May 25, Lon rated it liked it.

A Brief History of Time

Didn't like the computer-generated graphics that served as illustrations. Really I read this because the library didn't have his newest book called The Grand Design.

Disappointments aside, Hawking does have a gift for explaining these theories and their bizarre implications for the general reader. I can't imagine anyone less trained than myself to grasp the science behind these concepts; fortunately, no background in upper math or physics is presupposed. What I get is an almost dizzying sense of awe and wonder and, yes, giddiness over the mind-bending, trippy, conceptual gymnastics Hawking presents.

May 31, Deanne rated it really liked it Shelves: One of the greatest minds, a reminder that it's easy to dismiss someone based on their ability to communicate or their disadvantages.

I work in a Neuro theatre and often deal with people who due to illness or injury find it hard to respond, wonder how they feel I treated them. As for the book, love science and find black holes fascinating even if I had to read the book several times to understand exactly what professor Hawking meant. Nov 24, Roewoof rated it it was amazing.

This book is gorgeous. Let's get that out of the way. The illustrations and photos go a long way to engage the reader in a way that draws them further into the subject. The language is accessible for anyone who might be interested in reading. Often science books use language that seems to want to repel people from being interested in the subject it's discussing where with this book, you get the sense that Hawking really wants people, and children to learn and understand the concepts that he's ex This book is gorgeous.

Often science books use language that seems to want to repel people from being interested in the subject it's discussing where with this book, you get the sense that Hawking really wants people, and children to learn and understand the concepts that he's explaining. A lot has been made out of intelligence and how children who don't understand or are interested in science or mathematics are not intelligent, where in reality we have to consider how the subject are being explained to them, and reevaluate how differently people perceive the world around them and learn.

One size does not fit all. And yet, this book is a joy to read. I love taking one chapter at a time, and I don't feel like I'm reading an academic book at all. Science becomes an art, like fiction, interesting and marvelous. Granted, I always did enjoy science, but I think everyone enjoys science.

There isn't a person on the face of the planet that isn't curious about the world they live in and how it works. I can't wait to hand this book over to my children when they're a little older, and just watch it get read over and over again. May 08, Julien V rated it it was amazing Shelves: This was way harder to read than I would've thought, being a worldwide "popular science" bestseller.

It's probable that most people bought that book and just kept it on their coffee table to impress visitors. Some stuff about black holes and the life of the universe simply blew my mind. In the later chapters, I had a hard time distinguishing proper science form boundless speculations, but I guess that's the state of the art in quantum physics meeting general relativity whew!

May 22, Jonathan rated it really liked it Recommends it for: Those seeking a good introduction to modern physics. Life, the universe, and everything.

We know the answer 42 , but have we learned to ask the question? In these two books, conveniently collected into one exceedingly well-produced volume, Stephen Hawking sets forth the fundamental thinking underlying modern cosmology. From this vantage point, he also probes some of those deeper questions which naturally follow from the empirical study.

Though t Life, the universe, and everything. Though the title would suggest, well, a history book, the possible origins of the universe occupy only a portion of the discussion. Of these latter two in particular are of great interest: Both theories completely overthrew the conventional wisdom which had preceded them, both agree to a high degree of accuracy with empirical observation — and both are mutually exclusive to the other.

A Brief History Of Time Summary

With these tools of the trade, incomplete though they are, in hand, Hawking then does turn his attention to their implications on the origin and development of the universe. Much of the discussion centers around singularities — termination points on the space-time continuum at which infinite density results in infinite temperature, the cessation of time, and a complete breakdown of all known laws of science.

Hawking handles two examples: But Hawking also introduces another possibility, that there might be no beginning singularity at all. In this case, space-time could be viewed as a finite, unbounded expanse, like the surface of a ball but in four dimensions instead of three. Thus, the universe had no beginning, no moment of creation, and by implication, no creator. In The Universe in a Nutshell , Hawking continues his discussion of advanced physics studies and their implications on the observable world.

Having laid the foundations in the previous book, here he tackles a number of topics, from string theory to time travel, in chapters than can be read more or less independently.

Collected as the two are here in one volume, Universe reads more like a set of extended appendices to Brief History , which probably aids comprehension as well as presentation. Nevertheless, the latter does provide a primer to several trendy topics as well as provide ammunition for a few good physics puns braaaaaaaanes , and thus is worth at least a glance.

The narrative will move, mostly seamlessly, from scientific explication to philosophical speculation, but is never didactic in the first case and never dogmatic in the second. Though easy to read and follow Brief History contains just one equation — guess which one , this conversational tone does have its drawbacks. Those who have studied physics at the university level will find the collection a good refresher, but not plumbing any uncharted waters.

Another detriment stems from the lack of mathematical proofs: While most of the fundamental theories discussed are universally accepted, many of the conjectures the author makes are not, and without being able to consider the step-by-step reasoning the reader must simply take them on faith.

I understand the reasoning here — the book is a primer, not a college text — but I did find myself wishing some of the sweeping claims were given more support. That being said, both of those complaints can be rectified by further study, and Hawking does provide a long list of references. I highly recommend that anyone wishing to tackle the subject start with this particular edition ISBN Not only do you get two books in one, but the whole volume is filled with charts and diagrams that illustrate otherwise difficult-to-picture concepts.

This volume is an excellent way to dive into that discussion. Mar 14, Geoffrey rated it really liked it. Different version, perhaps? I had originally downloadd a copy of "A Brief History of Time" many years ago at a used bookstore and it just sat on my bookshelf collecting dust. It looked a bit overwhelming to read. I gotta say, I was blown away by the amount of knowledge crammed inside this page coffee-table style book. The full color illustrations throughout the pages in this book make what you're reading all the more fascinating.

Stephen Hawking explains the mysteries of the universe in a way that the layman can comprehend. He "dumbs" it all down for the rest of us in a way that makes astrophysics fun and easier to understand.

Science has only just begun to unlock the door to the many secrets of our expansive and ever expanding universe, and Stephen Hawking is one of the few greats who had the key. You get a crash course in Einstein's general relativity, quantum theory, The Big Bang theory, black holes, possible advanced civilizations, time travel, space travel among the stars by the use of wormholes, and so much more!

So, if once upon a time you were one of those kids who fell asleep during science and astronomy lectures in high school, who has now become interested in astrophysics as an adult but have so little free time; then this book is for you. I just heard the sad news that Stephen Hawking died this morning at age He had been physically debilitated most of his life by Lou Gehrig's Disease. He will be missed. There are many styles of reading.

One can skim a book once, then use it as reference in the future. Or one can carefully pour over every word, trying to absorb every possible nuance that an author weaves through his work. I think neither approach is appropriate for most readers of this book.

The Illustrated A Brief History of Time

The central theme of this book is the human quest for understanding, with a sub-theme of balancing the anthropic principle: It does not take deep scientific knowledge to understand this. However, Hawking takes great care to prevent a backlash from this understanding: Did the universe begin the way it did for the sole purpose of allowing creatures like us to exist?

If we take the anthropic principle too far, we are using science to support divine creation and thus undermining the quest to understand nature. There is also a second, less clearly defined division: While the conclusion is pithy, it very effectively sums up Hawking's hope for the future: Not only will humanity someday discover the unified law of nature, but soon enough this understanding will common to all humanity, just as Newtonian physics is taught to school children today.

However, I think Hawking does a good job explaining things in ways most people can understand, to a point. About halfway through the book, he seems to give up on this, perhaps thinking, if you have made it this far, you are either versed enough in physics to keep up, or you have resigned yourself to never really getting it, and thus he devotes less energy to dumbing the content down too much. However, the book does not drag. It is entertaining all the way through. Hawking is witty and fun-loving, laying out some of his hijinks, and being self-deprecating to the point of being high and mighty, a very clever trick.

It is profound and entertaining. The only thing keeping it 4 stars instead of 5 is the fact that I feel like I will always be missing something by not being an expert in cosmology. Aug 19, Galicius rated it liked it Shelves: Hawking has two long chapters on black holes.
