Three Essays In Phenomenology And Ontology [Bok / Häftad]

When the downtrodden animals of Manor Farm overthrow their master, Mr Jones, and take over the farm themselves, they imagine it is the beginning of a life of freedom and equality. But gradually a cunning, ruthless elite among them, masterminded by the pigs Napoleon and Snowball, starts to take control. Soon the other animals discover that they are not all as equal as they thought, and find themselves hopelessly ensnared as one form of tyranny is replaced with another. Orwell's chilling 'fairy story' is a timeless and devastating satire of idealism betrayed by power and corruption.

<p><b>DROPOUT. </b><b>PACIFIST. </b><b>PHYSICIST. </b><b>CASANOVA. </b><b>REFUGEE. </b><b>REBEL. </b><b>GENIUS.</b><br/><b>THINK YOU KNOW EINSTEIN? THINK AGAIN</b><br/><br/>His face is instantly recognisable. His name is shorthand for genius. Today, he's a figurehead as much as a man, symbolic of things larger than himself: of scientific progress, of the human mind, even of the age. But who was Einstein really?<br/><br/>The Nobel Prize-winning physicist who discovered relativity, black holes and E = mc2, dined with Charlie Chaplin in Hollywood and was the inspiration for (highly radioactive) element 99, Albert Einstein was also a high school dropout with an FBI file 1,400 pages long.<br/><br/>In this book, Samuel Graydon brings history's most famous scientist back to life. From his lost daughter to escaping the Nazis, from his love letters to unlikely inventions, from telling jokes to cheer up his sad parrot Bibo to refusing the Presidency of Israel, through the discoveries and thought experiments that changed science, <i>Einstein in Time and Space </i>tells 99 unforgettable stories of the man who redefined how we view our universe and our place within it.</p>

<p>Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born . . .<br/><br/>With lightness and magic, here Rovelli traces the ongoing adventure of his own cutting-edge research, of the uncertainty and joy of going where we've not yet been. Guiding us to the edge of theory and experiment, he invites us to go beyond, to experience the fever and the disquiet of science. Here is the extraordinary life of a white hole.</p>

Do you know the basics of general relativity?<br/>Do you want to know something of what more there is?<br/>Do you wonder how the theory of relativity came into being?<br/><br/>Then this book is for you!<br/><br/>Partial contents:<br/><br/>- Black holes and gravitational collapse<br/><br/>- Cosmological solutions of Einstein's field equations<br/><br/>- Gravitational waves<br/><br/>- Space-time singularities<br/><br/>- The problem of motion for massive particles<br/><br/>- A collection of exact solutions of Einstein's field equations<br/><br/>- A history of Einstein's creation of the theory of relativity in the years 1905-1915<br/><br/>- A short course for repetition of the basics of general relativity<br/><br/>- Bibliography, references, and index<br/><br/>The book, although not very advanced, covers a number of topics not often seen in text books. The selection, of course, refelects my own interests. The different chapters may to a large extent, though not completely, be read in any desired order.<br/><br/>The author has a PhD in theoretical physics and is lecturer of mathematics. He has for many years taught physics and mathematics at senior high school as well as university level.

Frequently Asked Questions About The Universe [Bok / Häftad]

<p>The received wisdom in quantum physics is that, at the deepest levels of reality, there are no actual causes for atomic events. This idea led to the outlandish belief that quantum objects - indeed, reality itself - aren't real unless shaped by human measurement. Einstein mocked this idea, asking whether his bed spread out across his room unless he looked at it. And yet it remains one of the most influential ideas in science and our culture.<br/><br/>In <i>Escape from Shadow Physics</i>, Adam Forrest Kay takes up Einstein's torch: reality isn't mysterious or dependent on human measurement, but predictable and independent of us. At the heart of his argument is groundbreaking research with little drops of oil. These droplets behave as particles do in the long-overlooked quantum theory of pilot waves; crucially, they display quantum behaviour while being described by classical physics.<br/><br/>What if the original doubters of our quantum orthodoxy (not least Einstein himself) were onto something? What if pilot wave theory was right all along? In that case, our whole story of twentieth-century physics is topsy-turvyand we must give up the idea that reality is simply too weird to grasp. Weird it may still be, but a true understanding of nature now seems within our reach.</p>
