Define Universe And Give Two Examples

How patterns--from diagrams of spacetime to particle trails revealed by supercolliders--offer clues to the fundamental workings of the physical world. Our universe might appear chaotic, but deep down it's simply a myriad of rules working independently to create patterns of action, force, and consequence. In Ten Patterns That Explain the Universe, Brian Clegg explores the phenomena that make up the very fabric of our world by examining ten essential sequenced systems. From diagrams that show the deep relationships between space and time to the quantum behaviors that rule the way that matter and light interact, Clegg shows how these patterns provide a unique view of the physical world and its fundamental workings. Guiding readers on a tour of our world and the universe beyond, Clegg describes the cosmic microwave background, sometimes called the "echo of the big bang," and how it offers clues to the universe's beginnings; the diagrams that illustrate Einstein's revelation of the intertwined nature of space and time; the particle trail patterns revealed by the Large Hadron Collider and other accelerators; and the simple-looking patterns that predict quantum behavior (and decorated Richard Feynman's van). Clegg explains how the periodic table reflects the underlying pattern of the configuration of atoms, discusses the power of the number line, demonstrates the explanatory uses of tree diagrams, and more.

A thrilling biography of the universe, as seen through the lens of today’s most cutting-edge scientific thinking. Here’s the book that explains the universe. You Are Here is an exhilarating journey that shows the cosmos as it has never been seen before. From the smallest parts of matter to the largest structures in the universe, Christopher Potter traces the life of the universe from theories of its conception to theories of its eventual fate. Along this heart-stopping voyage from quarks to galaxies, he writes entertainingly about the history and philosophy of science. With wisdom and wonder, Potter traverses the cosmos from its formation to its eventual end – while exploring everything in between. Some questions You Are Here sets out to answer: • What is this ‘everything’ that has evolved from nothing? And what do we mean by everything? • What stuff is ‘nothing’ made out of? • If the universe contains everything there is then what is it contained in? • Where are we in the universe? • Is there room for God in a material universe? • How scared should we be? • What fate awaits the universe? Science actually has answers to these questions, and in You Are Here, Potter will explain them to you.

This book is an elementary introduction to geometric topology and its applications to chemistry, molecular biology, and cosmology. It does not assume any mathematical or scientific background, sophistication, or even motivation to study mathematics. It is meant to be fun and engaging while drawing students in to learn about fundamental topological and geometric ideas. Though the book can be read and enjoyed by nonmathematicians, college students, or even eager high school students, it is intended to be used as an undergraduate textbook. The book is divided into three parts corresponding to the three areas referred to in the title. Part 1 develops techniques that enable two- and three-dimensional creatures to visualize possible shapes for their universe and to use topological and geometric properties to distinguish one such space from another. Part 2 is an introduction to knot theory with an emphasis on invariants. Part 3 presents applications of topology and geometry to molecular symmetries, DNA, and proteins. Each chapter ends with exercises that allow for better understanding of the material. The style of the book is informal and lively. Though all of the definitions and theorems are explicitly stated, they are given in an intuitive rather than a rigorous form, with several hundreds of figures illustrating the exposition. This allows students to develop intuition about topology and geometry without getting bogged down in technical details.

Understanding Life, Third Editionis intended for non-major biology students.--General Biology (non-majors)-Principles of Biology

No philosophical idea, no matter how small, can live alone. Ideas always gain their force, power, and life from their surroundings - their ecosystem. The ecosystem of ideas defended in this book comes from the ancient Greek philosopher Aristotle and his medieval interpreter, Thomas Aquinas. The ongoing relevance of their philosophical thought to twenty-first century issues is opened up in fascinating ways in this book. Life, the Universe, and Everything is the product of thirty years of teaching introductory courses in philosophy. Assuming no prior background, it only requires of readers an enquiring mind and a willingness to think carefully. An ideal guide to the big questions we face.

The acclaimed author of Einstein’s Dreams tackles "big questions like the origin of the universe and the nature of consciousness ... in an entertaining and easily digestible way” (Wall Street Journal) with a collection of meditative essays on the possibilities—and impossibilities—of nothingness and infinity, and how our place in the cosmos falls somewhere in between. Can space be divided into smaller and smaller units, ad infinitum? Does space extend to larger and larger regions, on and on to infinity? Is consciousness reducible to the material brain and its neurons? What was the origin of life, and can biologists create life from scratch in the lab? Physicist and novelist Alan Lightman, whom The Washington Post has called “the poet laureate of science writers,” explores these questions and more—from the anatomy of a smile to the capriciousness of memory to the specialness of life in the universe to what came before the Big Bang. Probable Impossibilities is a deeply engaged consideration of what we know of the universe, of life and the mind, and of things vastly larger and smaller than ourselves.
