### Read & download The Poincaré Conjecture In Search of the Shape of the Universe

Henri Poincaré was one of the greatest mathematicians of the late nineteenth and early twentieth century He revolutionized the field of topology which studies properties of geometric configurations that are unchanged by stretching or twisting The Poincaré conjecture lies at the heart of modern geometry and topology and even pertains to the possible shape of the universe The conjecture. So the shape of the universe It s a giant ball right Especially when you think of its beginning in a big bang But that brings up the awkward uestion of what s outside the ball Space universe is not infinite It s believed to be finite but without a boundary It becomes easier to understand this if you consider two dimensional beings living in a spherical the two dimensional surface of a ball universe Their universe is finite but has no boundaries There are no edges and if they start off from one point and keep going in the same direction they ll come back to where they started Our universe is finite and without boundary in the same way If you get on a spaceship and keep going in the same direction eventually you ll be back in the same neighborhood This one is harder to imagine isn t it In the case of two dimensional people living on a sphere we can see how it can be finite but without boundary because we can see how the sphere bends in a third dimension But how is it for our three dimensional universe There s no fourth dimension to bend in Reading this book didn t make it any easier for me to really understand how the universe can be finite but without a boundary All I can do is uote the two dimensional analogy but I m still a three dimensional earthling But even assuming that the universe is finite and without boundary is it a three sphere To go back to the two sphere analogy just because Magellan sailed in the same direction and came back to where he started doesn t mean that the earth is a sphere It can also be doughnut shaped and the same would still happen No one really knows what the shape of the universe is There s a lot of evidence for it being flat whatever that means And the Poincare Conjecture It says that a finite no boundary space that is simply connected is a three sphere This uestion is obviously of great interest both to mathematicians and to the physicists studying the geometry of the universe We still don t know if the universe is simply connected or not A ball is simply connect but something like a doughnut is not simply connected Unlike Reimann s Hypothesis the Poincare Conjecture was finally proved after much heartbreak and agony by an eccentric Russian mathematician named Gregori Perelman who didn t even accept the award for it The book tells the story of the conjecture and the man who proved it Good pop science and math history A Passion for More century He revolutionized the field of topology which studies properties of geometric Kodak and the Lens of Nostalgia configurations that are unchanged by stretching or twisting The Poincaré Spojrzenie na sztukę conjecture lies at the heart of modern geometry and topology and even pertains to the possible shape of the universe The Nue conjecture.

States that there is only one shape possible for a finite universe in which every loop can be contracted to a single pointPoincaré's conjecture is one of the seven millennium problems that bring a one million dollar award for a solution Grigory Perelman a Russian mathematician has offered a proof that is likely to win the Fields Medal the mathematical euivalent of a Nobel prize in Augus. This book was in the mathematics section in the library and I was expecting something mathematics focused Hence I was disappointed by the history lesson this book turned out to be Except for the initial confusion it was a nice read

My meeting with this book fell considerably short of love at first sight Not saw it on sale yesterday at a Melbourne bookstore and asked if I thought it might be interesting I picked it up glanced at the less than brilliant cover and leafed through it for a minute or two; the writing seemed lackluster and the first anecdote I found was one I'd seen before I was about to put it back when I reconsidered It cost 10 and was evidently

So – the shape of the universe It’s a giant ball right? Especially when you think of its beginning in a big bang But that brings up the awkward uestion of what’s outside the ball Space universe is not infinite It’s believed to be finite but without a boundary It becomes easier to understand this if you consider

There was some explanation earlier in the book but later explanation was poor I came away with little understanding of how the Poincare conjec

Why is this book not widely read? It's at least as good as books like Fermat's Last Theorem with far mathematical content If any layman wants a glimpse into the world of top level mathematics I cannot recommend a better book

I've been interested in the Millennium problems since I first read about them several years ago It was exciting to read about the first one to be solved I never took topology in college though so I have to admit

This book was in the 'mathematics' section in the library and I was expecting something mathematics focused Hence I was di

As a recent grad student in mathematics I found this book incredibly interesting It made me want to go on and get my PhD in manifold theory

The fact is I would need infinitive sets of lifes to read all the books I want and another set of infinitive lifes to put into practice everything I read in all the books I would achieve to read in those other infinite sets of lifes certainly an infinite number of books And yet I would need an infinite memory to

This was a decent book but a bit of a hard readFirstly the book introduces many concepts by name with some short descriptions and then goes on to discuss them in some ualitative detail; how one concept leads to another; how concepts fail to connect For me at least this was difficult to follow Granted in order to truly understand what is being discussed you would need to understand the mathematics; perhaps this is just
