'Includes exciting recent advances in studying gravity and its cosmic manifestations.' Lord Martin Rees, Astronomer Royal, former President of the Royal SocietyA fascinating historical account of how we have reached our current understanding of gravity.There have been sensational developments in gravitational physics in recent years. The detection of gravitational waves - ripples in the fabric of space - has opened a new window on the universe. These waves are produced by the most cataclysmic events in the universe - the collisions and mergers of black holes and neutron stars. There have also been great strides in our understanding of supermassive black holes. We now know that a black hole with a gargantuan mass lies at the heart of every galaxy, and we even have an image of one such beast. Gravity: From Falling Apples to Supermassive Black Holes provides an engaging and accessible account of how we have reached our current understanding of gravity and places these amazing discoveries in their true context.Gravity: From Falling Apples to Supermassive Black Holes is written in a captivating historical style with stories about the researchers of the past and present that illuminate many key ideas in astronomy and physics. The historical material leads from discussions of the early cosmologies to the great breakthroughs of Tycho and Kepler. We then consider Galileo's contributions to astronomy and mechanics, and the significance of Jeremiah Horrocks's ideas to the Newtonian revolution that would follow. Newton's theories brought about a new scientific age and his description of gravity was unrivalled for over two centuries until it was superseded by Einstein's description in terms of curved spacetime. The outlandish predictions of Einstein's theory have been confirmed again and again, including black holes and gravitational waves. Finally, we move on to more speculative ideas including Hawking radiation and primordial black holes and attempts to find a quantum theory of gravity.

The Physical World offers a grand vision of the essential unity of physics that will enable the reader to see the world through the eyes of a physicist and understand their thinking. The text follows Einstein's dictum that 'explanations should be made as simple as possible, but no simpler', to give an honest account of how modern physicists understand their subject, including the shortcomings of current theory. The result is an up-to-date and engaging portrait of physics that contains concise derivations of the important results in a style where every step in a derivation is clearly explained, so that anyone with the appropriate mathematical skills will find the text easy to digest. It is over half a century since The Feynman Lectures in Physics were published. A new authoritative account of fundamental physics covering all branches of the subject is now well overdue. The Physical World has been written to satisfy this need.The book concentrates on the conceptual principles of each branch of physics and shows how they fit together to form a coherent whole. Emphasis is placed on the use of variational principles in physics, and in particular the principle of least action, an approach that lies at the heart of modern theoretical physics, but has been neglected in most introductory accounts of the subject.

The Cosmic Mystery Tour takes us on a lightning tour of the mysteries of the universe enlivened by brief stories of the colourful characters who created modern science. It explores hot topics in physics and astronomy, including the recent discovery of gravitational waves; the quest for the origin of dark matter; the study of the supermassive black hole at the centre of the galaxy; the ongoing search for Earth-like exoplanets; the search for signals from extraterrestrials; and the development of technologies to send spacecraft to the stars.The first part of the book explores the laws that govern the universe. Physics is a spiritual quest to find deep meaning in the cosmos. Its goal is to provide a concise, but accurate description of the world that accounts for all the amazing features that it contains. The second part takes a look at the history of the cosmos, studies its geography and explores some of its architectural highlights such as red giants, white dwarfs, neutron stars and the ultimate cosmic mysteries-supermassive black holes. The last part considers the possibility that life might exist elsewhere in the universe, and explores the cosmos from the outer fringes of science fiction to the ongoing search for alien civilizations.

Artists and scientists view the world in quite different ways. Nevertheless, they are united in a search for hidden order beneath surface appearances. The quest for eternal geometrical designs is also seen in the sacred mathematical patterns created by the world's great religions. Tibetan monks fashion chalk mandalas representing the emergence of order in the universe. Moslem architects wrap their buildings in elaborate abstract tessellating designs.Celestial Tapestry places mathematics within a vibrant cultural and historical context. Threads are woven together telling of surprising influences that pass between the Arts and Mathematics. The story involves intriguing characters: the soldier who laid the foundations for fractals and computer art while recovering in hospital after suffering serious injury in the First World War; the mathematician imprisoned for bigamy whose books had a huge influence on twentieth century art; the pioneer clockmaker who suffered from leprosy; the Victorian housewife who amazed mathematicians with her intuition for higher-dimensional space.
