Where do asteroids come from and what are they made of? What clues do they hold about the evolution of the Solar System? Scientists have catalogued hundreds of thousands of asteroids, and many are thought to contain water and amino acids, the building blocks of life. Michael K. Shepard tells the fascinating story of their discovery, and what they can tell us about the history of our own planet.
Relax: no one understands technical mathematics without lengthy training but we all have an intuitive grasp of the ideas behind the symbols. To celebrate the 50th anniversary of the founding of the Institute of Mathematics and its Applications (IMA), this book is designed to showcase the beauty of mathematics – including images inspired by mathematical problems – together with its unreasonable effectiveness and applicability, without frying your brain.
Although widely criticised and hugely wasteful, The Common Agricultural Policy did at least afford British farmers a degree of support. Post-Brexit, that support will vanish – to be replaced with a woefully misconceived agricultural export drive that cannot possibly deliver. Bittersweet Brexit suggests a solution: paying workers decent wages in the agricultural sector could radically transform the nature of farming in Britain. It would improve yields, increase sustainability and ensure greater self-sufficiency at a time when food security is becoming a vital issue. This scenario provides a progressive, forward-thinking and optimistic future for food and farming in Britain, which, unlike many other industries, is currently being ignored.
There is more than one way to think. Most people are familiar with the systematic, rule-based thinking that one finds in a mathematical proof or a computer program. But such thinking does not produce breakthroughs in mathematics and science nor is it the kind of thinking that results in significant learning. Deep thinking is a different and more basic way of using the mind. It results in the discontinuous “aha!” experience, which is the essence of creativity.
Heart of Darkness describes the incredible saga of humankind’s quest to unravel the deepest secrets of the universe. Over the past thirty years, scientists have learned that two little-understood components–dark matter and dark energy–comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe’s fate. The story of how evidence for the so-called’Lambda-Cold Dark Matter’model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton.
The Big Bang, the birth of the universe, was a singular event. All of the matter of the universe was concentrated at a single point, with temperatures so high that even the familiar protons and neutrons of atoms did not yet exist, but rather were replaced by a swirling maelstrom of energy, matter and antimatter. Exotic quarks and leptons flickered briefly into existence, before merging back into the energy sea.This book explains the fascinating world of quarks and leptons and the forces that govern their behavior. Told from an experimental physicist’s perspective, it forgoes mathematical complexity, using instead particularly accessible figures and apt analogies.
The present Editorial introduces the Special Issue dedicated by the journal Universe to the General Theory of Relativity, the beautiful theory of gravitation of Einstein, a century after its birth. It reviews some of its key features in a historical perspective, and, in welcoming distinguished researchers from all over the world to contribute it, some of the main topics at the forefront of the current research are outlined.
‘Why’? Why is the world, the Universe the way it is? Is space infinitely large? How small is small? What happens when one continues to divide matter into ever smaller pieces? Indeed, what is matter? Is there anything else besides what can be seen? Pursuing the questions employing the leading notions of physics, one soon finds that the tangible and visible world dissolves — rather unexpectedly — into invisible things and domains that are beyond direct perception. A remarkable feature of our Universe is that most of its constituents turn out to be invisible, and this fact is brought out with great force by this book.
Today we know what no previous generation knew: the history of the universe and of the unfolding of life on Earth. Through the astonishing combined achievements of natural scientists worldwide, we now have a detailed account of how galaxies and stars, planets and living organisms, human beings and human consciousness came to be. And yet… we thirst for answers to questions that have haunted humanity from the very beginning.
In this comprehensive and engaging volume, medical historian Jonathan Reinarz offers a historiography of smell from ancient to modern times. Synthesizing existing scholarship in the field, he shows how people have relied on their olfactory sense to understand and engage with both their immediate environments and wider corporal and spiritual worlds. This broad survey demonstrates how each community or commodity possesses, or has been thought to possess, its own peculiar scent.
