Rhodri Evans tells the story of what we know about the universe, from Jacobus Kapteyn's Island universe at the turn of the 20th Century, and the discovery by Hubble that the nebulae were external to our own galaxy, through Gamow's early work on the cosmic microwave background (CMB) and its subsequent discovery by Penzias and Wilson, to modern day satellite-lead CMB research. Research results from the ground-based experiments DASI, BOOMERANG, and satellite missions COBE, WMAP and Planck are explained and interpreted to show how our current picture of the universe was arrived at, and the author looks at the future of CMB research and what we still need to learn. This account is enlivened by Dr Rhodri Evans' personal connections to the characters and places in the story.

Acclaimed popular-science writer Brian Clegg and popular TV and radio astronomer Rhodri Evans give us a Top Ten list of physicists as the central theme to build an exploration of the most exciting breakthroughs in physics, looking not just at the science, but also the fascinating lives of the scientists themselves. The Top Ten are: 1.Isaac Newton (1642-1727) 2.Niels Bohr (1885-1962) 3.Galileo Galilei (1564-1642) 4.Albert Einstein (1879-1955) 5.James Clerk Maxwell (1831-1879) 6.Michael Faraday (1791-1867) 7.Marie Curie (1867-1934) 8.Richard Feynman (1918-1988) 9.Ernest Rutherford (1871-1937) 10.Paul Dirac (1902-1984) Each of these figures has made a huge contribution to physics. Some are household names, others more of a mystery, but in each case there is an opportunity to combine a better understanding of the way that each of them has advanced our knowledge of the universe with an exploration of their often unusual, always interesting lives. Whether we are with Curie, patiently sorting through tons of pitchblende to isolate radium or feeling Bohr's frustration as once again Einstein attempts to undermine quantum theory, the combination of science and biography humanizes these great figures of history and makes the Physics itself more accessible. In exploring the way the list has been built the authors also put physics in its place amongst the sciences and show how it combines an exploration of the deepest and most profound questions about life and the universe with practical applications that have transformed our lives. The book is structured chronologically, allowing readers to follow the development of scientific knowledge over more than 400 years, showing clearly how this key group of individuals has fundamentally altered our understanding of the world around us.

'These minibiographies of women who persisted will move anyone with an avid curiosity about the world.' Publishers Weekly With a foreword by Athene Donald, Professor of Experimental Physics, University of Cambridge and Master of Churchill College. Ten Women Who Changed Science tells the moving stories of the physicists, biologists, chemists, astronomers and doctors who helped to shape our world with their extraordinary breakthroughs and inventions, and outlines their remarkable achievements. These scientists overcame significant obstacles, often simply because they were women. Their science and their lives were driven by personal tragedies and shaped by seismic world events. What drove these remarkable women to cure previously incurable diseases, disprove existing theories or discover new sources of energy? Some were rewarded with the Nobel Prize for their pioneering achievements -Madame Curie, twice - others were not and, even if they had been, many are still not the household names they should be. Despite living during periods when the contribution of women was disregarded, if not ignored, these resilient women persevered with their research, whether creating life-saving drugs or expanding our knowledge of the cosmos. By daring to ask 'How?' and 'Why?' and persevering against all odds, each of these women, in a variety of ways, has helped to make the world a better place. The scientists are: Henrietta Leavitt (United States, Astronomy); Lise Meitner (Austria, Physics); Chien-Shiung Wu (United States, Physics); Marie Curie (France, Chemistry); Dorothy Crowfoot Hodgkin (United Kingdom, Chemistry); Virginia Apgar (United States, Medicine); Gertrude Elion (United States, Medicine); Rita Levi-Montalicini (Italy, Biology); Elsie Widdowson (United Kingdom, Biology); Rachel Carson (United States, Biology).
