The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics
These black hole ideas are important...more
I was in the physics section of the library, and this book caught my eye. I have to admit that the title was the major contributing factor that incited me to read this. Now I have a soft spot for quantum mechanics and string theory (not to mention puppies, kittens and cheesecake, but that's an entirely different matter) and so it's no surprise that I j...more
I enjoyed learning about the physicists themselves. Their personalities, competitive yet respectful spirit, and comradery were the highlights of the book. The most memorable bits are Susskind's mus...more
I dislike how the emphasis of this book seems to be on this nebulous concept of "information" instead of in the physical states themselves from which this "information" is deduced. The world is made up of physical...more
It needs to be said, that this is not for everybody. Even if Leonard Susskind does a perfect job to explain even the more difficult concepts, what he talks about is still incredibly complex.
It needs to be read by somebody that has the basis for physics (but not too much: high school physics is enough to follow the reasoning), and is used to scientific reasoning.
That said, I would say this book is one of the few that classify still as not being technical (as I said before, you don...more

Chapter 2 - Black holes and the horizon at the Shwartzchild radius described. Einstein rejected black holes. Tidal forces are less at the horizon of large black holes. Einstein Equivalence Principle states that the effects of gravity and acceleration are indistinguishable.
Chapter 3 - Reimann proposed that space may be curved, an idea incorporated into General Relativity. Minkowski space incorporates space and time,...more
I recently critiqued Richard Panek's 4% Universe for what I considered to be poor science writing. Susskind is the antidote. On the whole, he is the clearest expositor of advanced physics concepts that I have encountered, much better than Bria...more
Susskind follows the events, developments, and personalities of the debate with a strong insider's knowledge and near reverence for the minds involved. He tends to go into lengthy asides about people and hits on string theory a bit harder than I think is needed but this is his book from his perspective and h...more
For the most part this book is a conversational discussion of many complicated concepts such as black holes, Quantum Mechanics, Quantum Gravity, and Sting Theory. There are times when it finds itself a bit long-winded. At times I get tired of Susskind blowing his own horn. There are times when I don't quite follow the explanations, but on the whole i...more
What was the issue? Hawking said he had proven that information that enters a black hole is lost forever. Susskind disagreed, mainly because that would mean that one of the fundamental tenets of physics -- that matter is never destroyed -- would be wrong. And...more
As a whole the book has too much science in it. I know I know, it's a book about Quantum Mechanics, thermal energy, space-time, partical difublators and time machines (not really som...more
Susskind not only follows the progression of some extremely...more
Hawking: seemed to prove that information is irretrievably lost in a black hole. Also, empty space full of super-flee...more
This is a very well written book about a lengthy debate in the scientific community about the rules of physics and their "universality", in a manner of speaking. Granted we really on get one side of the "argument", but he presents the opposition fairly and with enough detail to let the reader understand the gravity (pun intended) of the situ...more
Equivocation is my issue again. When physicists talk about the curvature of space-time, do then mean space? In spatial dimensions curves are familiar. However, the notion of curvature of time is not analogous to anything I can think of. This does i...more
Cosmology has been sexy since Carl Sagan, Richard Feynman, and Stephen Hawking stormed onto the scene three decades ago, popularizing science for the masses. In The Black Hole War, Susskind plays on our insatiable appetite for the gee-whiz moment, combining lucid explanations for some complex ideas with stories that tend to confirm the eccentricities of the highly intelligent. In fact, it's the author's knack for teaching and his conversational prose that make the book accessible and therefore a...more
I finished the book in tears because the content is so powerful.
My only trouble is that I have to just trust that the math he refers to is "right." For the most part, though, he relie...more
Obviously not me. I'm going to be optimistic and assume that it's possible to make clear why this conservation of information theorem is so important, and why the holographic principle is worth calling a principle. And thus Susskind, in failing to mak...more
