On the Inside of a Marble


Book Description

Keeping in mind that we can only see the universe from the comfort of our home galaxy, Bascom begins his text by meticulously laying the necessary groundwork to understand the Big Bang’s mathematics without using any equations. He then paints a freeze-frame picture of our universe as if we had taken a three-dimensional picture with a giant camera. Within this picture, he traces forces beginning with the smallest (a single atom) to the biggest (the cosmos), keeping in mind that in this frozen moment everything further away from the observer spatially is also further away from the observer in time; that is, older. Soon a very real and very vivid image of the Big Bang appears (especially in things that are loud or hot), echoing down through time and into our everyday lives, reflected in every atom during every measurement. Then, slowly but deliberately, Bascom unfreezes this picture, ratcheting each moment from one to the next, showing us how and why quantum particles are constantly in contact with the Big Bang and why that allows the particles to pop in and out of existence from moment to moment, what a photon is, and what exactly we mean when we say that free space has energy. Whether you’re interested in the Big Bang, the weirdness of quantum mechanics, or simply enjoy thinking about the biggest, loudest, and oldest things in our universe, this book will help you question your deepest notions about time and space, while staying firmly rooted in empirical observation. Throughout the text, Bascom sidesteps traditional non-fiction modes, using colorful explanations and vivid imagery to place the reader in simultaneous contact with both the Big Bang and fundamental particles. As a result, Bascom provides the tools and language necessary to contemplate the strangeness of our universe.




Information and the Internal Structure of the Universe


Book Description

Not so if the book has been translated into Arabic. Now the reader can discern no meaning in the letters. The text conveys almost no information to the reader, yet the linguistic informa tion contained by the book is virtually the same as in the English original. The reader, familiar with books will still recognise two things, however: First, that the book is a book. Second, that the squiggles on the page represent a pattern of abstractions which probably makes sense to someone who understands the mean ing of those squiggles. Therefore, the book as such, will still have some meaning for the English reader, even if the content of the text has none. Let us go to a more extreme case. Not a book, but a stone, or a rock with engravings in an ancient language no longer under stood by anyone alive. Does such a stone not contain human information even if it is not decipherable? Suppose at some point in the future, basic knowledge about linguistics and clever computer aids allow us to decipher it? Or suppose someone discovers the equivalent of a Rosetta stone which allows us to translate it into a known language, and then into English? Can one really say that the stone contained no information prior to translation? It is possible to argue that the stone, prior to deciphering contained only latent information.
