Drawing from Scientific American's "Fact or Fiction" and "Strange But True" columns, we've selected fifty-eight of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

    In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    Although it is usually seen as an unqualified success, the Battle for Normandy was actually a much more closely fought affair. In The D-Day Deception the author and journalist Alex Gerlis explores whether it would have been won at all without the Allied deception operation. It was not until the 1970s that details began to emerge the Allies’ top secret and audacious deception plan. Operation Fortitude succeeded in confusing the Germans about where the Allies were going to land: would it be Normandy, or the Pas de Calais? The D-Day Deception looks at the part the deception played in the eventual Allied victory and asks to what extent it may have been helped by those in the German High Command and intelligence organizations who by 1944 wanted to see a swift end to the war. Alex Gerlis was born in Grimsby, Lincolnshire and now lives with his family in West London. He was a BBC journalist for over 25 years, leaving in 2011 to concentrate on his writing. He is the author of The Best of Our Spies, a highly acclaimed espionage thriller based on D-Day and especially the deception operation that played a big part in its success. The Best of Our Spies was published in December 2012, since when it has featured prominently in the Amazon Kindle Spy best-selling lists and has over 180 Amazon reviews.

    V. and VI. of The History of the United States for the Year 1796, in which the Charge of Speculation against Alexander Hamilton, late Secretary of the Treasury, is fully refuted. Written by himself. Philadelphia: Printed for John Fenno, by John Bioren, 1797.ABOUT THE AUTHOR:Alexander Hamilton was a Founding Father, soldier, economist, political philosopher, one of America's first constitutional lawyers and the first United States Secretary of the Treasury. He has been described as one who "more than any other designed the Government of the United States": As Secretary of the Treasury, Hamilton was the primary author of the economic policies of the George Washington Administration, especially the funding of the state debts by the Federal government, the establishment of a national bank, a system of tariffs, and friendly trade relations with Britain. He became the leader of the Federalist Party, created largely in support of his views, and was opposed by the Democratic-Republican Party, led by Thomas Jefferson and James Madison.

    As recently as 1918, a pandemic of influenza claimed over 50 million lives worldwide. The advent of drugs and vaccines led to an era of hope when we thought our battles with infectious disease were won, but our optimism has been eroded by the recognition that many pathogens have the capacity to transform themselves and escape our efforts to eradicate them. Are we now facing an inevitable repeat of a calamity such as the 1918 influenza pandemic or the Black Death? Can we anticipate and thwart such an event, or are we wilfully creating the conditions that would promote the emergence of new and highly virulent human infectious disease?Sunetra Gupta is Professor of Theoretical Epidemiology at the University of Oxford specialising in infectious diseases. She holds a bachelor's degree from Princeton University and a Ph.D. from the University of London. She has been awarded the Scientific Medal by the Zoological Society of London and the Royal Society Rosalind Franklin Award for her scientific research. She is also a novelist whose books have been awarded the Sahitya Akademi Award, the Southern Arts Literature Prize, shortlisted for the Crossword Award, and longlisted for the DSC and Orange Prizes.

    During World War I, the young women who were hired to work in America's radium watch dial factories were considered the lucky ones. They were paid well, they got to work with the luminous element dubbed "liquid sunshine" that was all the rage, and they were helping the war effort by providing instruments that shone in the dark. And their bodies literally glowed because of the amount of radium they were ingesting. In her new book, The Radium Girls: The Dark Story of America's Shining Women, author Kate Moore gives voice to two groups of workers who became horribly ill and fought back against the companies that poisoned them. Using diaries and letters from the women, their statements in court documents, medical records and archived x-rays, as well as using ancestry documents to track down their relatives for interviews, Moore showcases the forgotten young women whose legal fight led to life-changing workplace safety regulations amid one of the biggest scandals of America's twentieth century. Preorder and find out how their story ends on May 2.

    The Age of Reason represents the results of years of study and reflection by Thomas Paine on the place of religion in society.Paine wrote: "Of all the tyrannies that affect mankind, tyranny in religion is the worst; every other species of tyranny is limited to the world we live in; but this attempts to stride beyond the grave, and seeks to pursue us into eternity."The cool rationale of Paine's The Age of Reason influenced religious thinking throughout the world; and its pervasieve influence continues to the present day.

    It had an illustration that captivated him–a diagram showing Earth’s interior as it would look if you cut into it with a large knife and removed about a quarter of its bulk. The idea of lots of startled cars and people falling off the edge of that sudden cliff (and 4,000 miles is a pretty long way to fall) was what grabbed him in the beginning, but gradually his attention turned to what the picture was trying to teach him: namely that Earth’s interior is made up of several different layers of materials, and at the very centre is a glowing sphere of iron and nickel, as hot as the Sun’s surface, according to the caption. And he very clearly remembers thinking: “How do they know that?”Bill’s storytelling skill makes the “How?” and, just as importantly, the “Who?” of scientific discovery entertaining and accessible for all ages. He covers the wonder and mystery of time and space, the frequently bizarre and often obsessive scientists and the methods they used, and the mind-boggling fact that, somehow, the universe exists and against all odds, life came to be on this wondrous planet we call home.

    A classic biblical analysis from the great physicist and philosopher

    

    That unfortunate situation began to change when Einstein published several of the papers and speeches contained in this book which explain the central core of the theory in clear and often beautiful language accessible to any interested reader.In addition to lucid explications of both the Special and General theories, Einstein holds forth on the principles of research, the nature of scientific truth, and the method of theoretical physics. He also offers acute analyses and appreciation of the work of such giants as Johannes Kepler, Isaac Newton, Clerk Maxwell, and Niels Bohr.
