On July 4, 2012, the announcement came that one of the longest-running mysteries in physics had been solved: the Higgs boson, the missing piece in understanding why particles have mass, had finally been discovered. On the rostrum, surrounded by jostling physicists and media, was the particle’s retiring namesake—the only person in history to have an existing single particle named for them. Why Peter Higgs? Drawing on years of conversations with Higgs and others, Close illuminates how an unprolific man became one of the world’s most famous scientists.

'Trinity' was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. This exceptional book - Trinity - tells the story of the bomb's metaphorical father, Rudolf Peierls; his intellectual son, the atomic spy, Klaus Fuchs; and the ghosts of the security services in Britain, the USA and USSR.

The second half of the 20th century witnessed a scientific gold rush as physicists raced to chart the inner workings of the atom. The stakes were high, the questions were big, and there were Nobel Prizes and everlasting glory to be won. Many mysteries of the atom came unraveled, but one remained intractable-what Frank Close calls the "Infinity Puzzle."

This short, smart book tells you everything you need to know about "nothing". What remains when you take all the matter away? Can empty space - "nothing" - exist? To answer these questions, eminent scientist Frank Close takes us on a lively and accessible journey that ranges from ancient ideas and cultural superstitions to the frontiers of current research, illuminating the story of how scientists have explored the void and the rich discoveries they have made there.

Following the discovery of the Higgs boson, Frank Close has produced this major revision to his classic and compelling introduction to the fundamental particles that make up the universe. Frank Close takes us on a journey into the atom to examine known particles such as quarks, electrons, and the ghostly neutrino, and explains the key role and significance of the Higgs boson. Along the way he provides fascinating insights into how discoveries in particle physics have actually been made, and discusses how our picture of the world has been radically revised in the light of these developments.

The charges of the proton and electron are opposite and equal, even though the proton is bigger. But why are they equal? This is one of the deepest unresolved puzzles of physics. Frank Close takes us on a journey into the quantum subatomic world of particles. He describes the strong and weak forces that operate alongside electromagnetism, the color and flavor charges, as well as the parallels between them, giving hints of a deeper unity.

Eclipses: What Everyone Needs to Know helps explain the profound differences between a 99.99 percent partial eclipse and true totality, and inform listeners how to experience this most beautiful natural phenomenon successfully. It covers eclipses of sun, moon, and other astronomical objects, and their applications in science, as well as their role in history, literature, and myth. It describes the phenomena to expect at a solar eclipse and the best ways to record them - by camera, video, or by simple handmade experiments.

The memo landed on Kim Philby's desk in Washington, DC, in July 1950. Three months later Bruno Pontecorvo, a physicist at Harwell, Britain's atomic energy lab, disappeared without a trace. When he resurfaced six years later, he was on the other side of the Iron Curtain.
