A universe of little black beach ballsReview Date: 2005-01-24
A mix of history and new theoryReview Date: 2000-07-31
Hawkins treats us to the theory only after 130 pages of his own views of the evolution of cosmological thought, complete with his take on the feuds, backbiting, and troubled waters of academic squabbling. His insights are interesting and his book a pleasure to read, but I had the troubling impression that I was being treated to someone else's dirty laundry all the while, though that's the way science works I suppose. Among opinions he expresses that ring true is that of the "HST bias," that results which come from HST observations are somehow given automatic priority over those of ground-based observations, a bias which is clearly not always warranted.
The most interesting part of his book, for me, was his detailed descriptions of his own observational programs - using a series of Schmidt plates of a single patch of sky, accumulated over a period of years, to search for faint variable stars. His hopes were to find microlensing events to bolster his theory. He ended up finding lots of previously unknown quasars, and finding new patterns of quasar variability spanning years, not months or weeks.
Hawkins is an unabashed UK promoter. I had to grin at many of his descriptions of the superior astronomy of the UK. He has a lot to brag about though.

"Inner Space" was edited and annotated by Rabbi Avraham Sutton, a disciple of Rabbi Kaplan who has become a great teacher of the inner Jewish traditions in his own right. Today he teaches in Jerusalem, where I merited to meet him, and was deeply impressed by his humility, generosity, kindness, and Torah learning.
A wise guide to an incomprehensible subject Review Date: 2004-12-26
Aryeh Kaplan was a great teacher who had a masterful ability to understand and make clear very difficult concepts. In this work he introduces the reader to the Kabbalah to the Sefirot, and then in the second section of the work writes of another difficult subject Meditation and Prophecy. Kaplan's great learning is evident throughout the work and it is highly readable, a great introduction to a most difficult subject matter. I myself however did not feel I was really in the reading mastering the material properly. But then I am not so high in the world of learning, and am not the best example.

A Work of Art!Review Date: 2007-04-12
It's the finest and most enjoyable mathematics book I've encountered to date, and that's taking into account the existence of many excellent math books. Certainly among books specifically on applied mathematics, this book is uniquely valuable.
The choice of topics, sequence of presentation, level of detail, use of examples, and clarity and elegance of exposition are all outstanding. Batschelet has crafted every chapter, section, paragraph, and even sentence with meticulous care and precision in the finest Swiss tradition.
If you've already studied mathematics through calculus, differential equations, probability, linear algebra, etc., this book is an especially good resource to review it all via a single coherent book.
To illustrate how much I cherish this book, I've bought two copies -- one to read, and the other in case the first is damaged and the book goes out of print.
If you love math, buy this book. If you just have an interest in math, buy this book and read it, and you may well come to love math.

The author's mind has no boundary....Review Date: 2002-02-03
The first chapter is an overview of the history behind the subject, via the work of people who contributed to our current understanding of gravity. And then, with a masterfull use of diagrams he gives the reader a taste of the simplicity of the equivalence principle and the need to tack on an additional dimension (time) to the 3-dimensional space of everyday experience. The Pound-Rebka experiment is discussed as one that illustrates the idea of the spacetime interval, and the role of time dilation is discussed via the possibility of practical space travel. And such enthusiasm in his dialog: "the universe will grow ever more exciting", he says, and looking at the developments now taking place in today's science, he is indeed correct.
Chapter 4 gives a fascinating overview of what the author calls the boomerang, which illustrates the action of curvature on nearby test masses. This thought experiment involves the motion of a spacecraft through an imaginary tunnel through the Earth. The author analyzes the motion from the standpoint of Newtonian physics and general relativity. Curvature as the "grammar of gravity" is the topic of the next chapter, with illustrations of the paths of ants on spaces of zero, positive, and negative curvature. A very intuitive treatment of parallel transport around a closed path on a curved surface is given. The tides are discussed as a natural manifestation of the gravitational influence of the Moon on Earth.
Must difficult for a layman to understand is how spacetime acts on masive objects, but the author explains it brilliantly in the next chapter, taught via the concept of "momenergy". This entity is a 4-vector, and the author uses it to show how its creation in a spacetime region can be written as the sum of 8 terms, reflecting the fact that the "boundary" of a four-dimensional block in spacetime consists of eight three-dimensional cubes. That the contents of these cubes sum to zero is the famous "boundary of a boundary is zero", which is discussed in the next chapter. This chapter is one of the best explanations ever given (at this level) of the physics behind spacetime curvature and massive objects. The actual mathematical quantification of curvature is detailed in chapters 8 and 9, using elementary mathematics. The author discusses nicely the famous Scharwzschild geometry.
Concepts of a more concrete nature are discussed in chapter 10, wherein the author discusses the famous Pound-Rebka experiment and planetary motion. This is followed by a discussion of the elusive gravitational waves in chapter 11. Again with a clever use of illustrations, the author explains the transverse property of gravitational waves, and compares gravitational waves with electromagnetic waves. The role of the quadrupole moment in the creation of gravitational waves is brought out briliantly by the author. He discusses briefly various attempts to detect gravitational waves.
Black holes are the topic of chapter 12, wherein the famous Penrose process for extracting energy from a black hole is discussed, and the "no-hair" theorem for black holes. A neat symbolic representation of the Bekenstein number of a black hole is given. The role of the Hawking process, connection quantum processes with the physics of black holes is briefly discussed. The author ends the book with a look at the expansion of the universe, the missing mass problem, and another very interesting topic that has gained much attention recently: the concept of gravitomagnetism. This is a "weak-field" prediction of general relativity, and predicts that the rotation of the Earth should influence the motion of orbiting satellites. This topic is currently bringing together ideas such as the quantum Zeno effect, Mach's principle, and the notorious "frame dragging" effect in general relativity. Experiments do measure it are currently in play and in the proposal stage, namely the LAGEOS and LAGEOS II experiments, which measure the gravitomagnetic orbital perturbation, which is known as the Lense-Thirring effect.
Able to "see" spacetimeReview Date: 2004-01-10
The book is intended as an introduction to general relativity, without much tensor formalism, but it does not neglect the geometrical underpinnings. It presents a very nice way to get at the physics, with creative and light-hearted diagrams.
I'm not so sure that Wheeler's own poems, which introduce many of the chapters, are a great success, but I admire and salute him for including them. Even his poetry helps to open additional doors to understanding general relativity.
A book that is truly beautiful.
A stunner of a bookReview Date: 1999-12-13
Wheeler is able to pull off a major accomplishment: He explains Einstein's General Relativity in a clear, straightforward manner, with a minimum of math. It's "conventional wisdom" that General Relativity is seriously serious stuff, the domain of hardcore Physics geeks. That doesn't faze Wheeler. He leads the reader along, gleefully pointing out the scenery, making it all look quite simple and understandable. And then all of a sudden, when you least expect it, you find he's derived and presented Einstein's field equations with only a teensy-tiny bit of algebra! Even if you know this stuff already, his presentation makes you think about it with a new perspective.
And did I mention the illustrations? They are really exceptional.
If you have any interest or dealings with GR, ya gotta have this book!
Awesome: from an MSEEReview Date: 2002-08-25
Unfortunately when a key subject left me rather clueless, (Boundary of a Boundary) I spent quite a few frustrated hours being uncertain on whether or not to continue reading without the support of the material on those pages. As it turned out, the subject became clearer once I read on and returned again. I never did grasp it as completely as the rest of the book.
The book contains the most enlightening description of transverse wave propagation I've ever seen. It also helps solidify one's understanding of interval and relativity.
Not a book to be read overnight.

GREAT BOOK!!!!!!!!!!Review Date: 2004-06-19
Gorgeous illustrations with just enough informationReview Date: 2004-02-17
I am impressed by the entire series of picture books by Seymour Simon and our family has been enjoying his books, one about each planet, which we are using as part of our homeschooling. I have found that many of the books that attempt to cover all topics about space end up skimping on important general information that Simon easily communicates, such as the temperature and how it compares to Earth, why humans could not survive on the planet, and the general weather conditions and how they compare. The way these comparisons are made really helps children understand the conditions on the planets. This series by Simon is also superior to other books about Jupiter because the photos are in color; they are real, stunning photos, not lame illustrations drawn by hand.
I highly recommend that any parent read these books to their children. Teachers and homeschoolers would find this book a wonderful book to use while teaching about Jupiter.

Rodda definitely has ended the book with room for sequelsReview Date: 2008-08-11
When Leo inherits an antique music box from his kind but dull great-aunt Bethany, he is flattered to be responsible for an object that has been in his family for generations. Little does he know that the beautifully painted box will be the source of an adventure that will bring him closer to understanding all the Langlander family stories that Bethany loved to share. Leo planned to respect the rules for the music box that had been handed down: don't wind it more than three times, don't turn the key or pick up the box while the music is still playing, and don't close the lid until the music has stopped. But when his annoying and defiant cousin Mimi comes to stay with him and his parents, she breaks the rules right away, thus setting in motion a perilous and exciting adventure that tests their loyalty, reveals much about the Langlander clan, and challenges Leo and Mimi to find strength and confidence in their true selves.
When Mimi winds the music box an additional turn, it brings to life the Blue Queen, one of the figures painted on the box. She snatches Mimi's dog Mutt and heads back to Rondo, the world painted on the box's sides. Despite Leo's warnings, Mimi is determined to follow the queen into Rondo to rescue Mutt. And against his better judgment, Leo goes with her. They find themselves in the street scene painted on one side of the box, but things are different from what they remember: there has been an earthquake in Rondo and much disorder.
A shady character calling himself Tom offers to help the two youngsters find their way to the Blue Queen's castle, but he is scared away by the police. Now Leo and Mimi are on their own and distrustful of everyone they meet. Do Conkers and his talking duck Freda really want to help them? What about the strange-looking Tye, who has the body of a woman and the face of a tiger? What are they to make of the tales of Jim and Polly, who tell them all about the Dark Times and a hero named Hal who thwarted the queen?
As they move closer and closer to the queen's castle, Leo and Mimi must work together to hatch a plan that will free the dog and get them home safely. They team up with a talking pig named Bertha and decide to confront the queen face to face. Along the way they learn about Rondo and begin to comprehend how Rondo and the Langlander family are connected.
THE KEY TO RONDO is great fun to read. Leo and Mimi make a fantastic pair, especially as they come to know each other better and work together to balance their strengths and weaknesses. The supporting characters are sympathetic, and the bad guys are just bad enough without being unbelievable. Young readers will enjoy the twists, turns and surprises; the writing is fresh and the adventure thrilling. Rodda's contribution to this otherworldly quest is a worthwhile one, and she definitely has ended the book with room for sequels. There are still many mysteries of Rondo to be revealed!

"The stars and galaxies that fill our view as we survey the depths of the universe are really just a froth delineating the massive, dark unseen structures beneath."
He is telling us that almost all of the matter of the universe is hidden from our view. All of the stars we see just account for 10% of the matter in the universe. The other 90% is invisible.
How does he arrive at this conclusion? A certain amount of mass is necessary to provide enough gravitational force to balance the opposite force in the universe, the force that drives stars away from each other. Without this mass, the stars would be hurtling off into space, not forming galaxies.
And the stars we can see only account for 10% of the necessary mass. What is the other 90%?
He answers this too. The other 90% of the matter of the universe is composed of black holes the size of beach balls and the mass of Jupiter.
What leads him to say that? He'll explain it all to you. It has to do with variations in the light of far-away quasars. He believes that this light is varying because it is being seen through the "lens" of a lot of little black holes that happen to exist in the line of sight between us and those quasars.
What is a quasar? What does baryonic mean? What is a black hole? What is inflation? There is a terrific glossary near the back of the book. It might be the best part of the book. You will learn a lot just from taking your time browsing through the glossary.
It is mind-boggling to me that all these millions of little black holes would have formed within the first millionth of a second of the universe's existence.
If there is a creator, she was certainly not hurried by our conception of time. She came from a place that isn't hampered by time constrictions.
He addresses the debate between the Big Bang and the Steady State theories, and he believes that the Big Bang necessarily supports the existence of a creator while the Steady State does not. I don't really see his point there.
If you choose to believe in a creator (and I can't think of a reason why you should back away from that idea, except for being utterly fed up with the nonsense of Noah chasing around the arctic to kidnap polar bears and haul them to the Middle East in a damn hurry) you are pretty well stuck with her (the creator) even with the Steady State theory. Wouldn't she have been the one who made the stars in the first place? That's her job, no?
This book also leaves us with the cheery thought that the world's scientists tend to be stubborn, jealous, impressed by status, rarely objective, and a bunch of annoying crapheads. Thank you for letting us know. It renews my faith in humanity.
