Albert Einstein’s theory of general relativity describes the effect of gravitation on the shape of space and the flow of time. But for more than four decades after its publication, the theory remained largely a curiosity for scientists; however accurate it seemed, Einstein’s mathematical code—represented by six interlocking equations—was one of the most difficult to crack in all of science. That is, until a twenty-nine-year-old Cambridge graduate solved the great riddle in 1963. Roy Kerr’s solution emerged coincidentally with the discovery of black holes that same year and provided fertile testing ground—at long last—for general relativity. Today, scientists routinely cite the Kerr solution, but even among specialists, few know the story of how Kerr cracked Einstein’s code. Fulvio Melia here offers an eyewitness account of the events leading up to Kerr’s great discovery. Cracking the Einstein Code vividly describes how luminaries such as Karl Schwarzschild, David Hilbert, and Emmy Noether set the stage for the Kerr solution; how Kerr came to make his breakthrough; and how scientists such as Roger Penrose, Kip Thorne, and Stephen Hawking used the accomplishment to refine and expand modern astronomy and physics. Today more than 300 million supermassive black holes are suspected of anchoring their host galaxies across the cosmos, and the Kerr solution is what astronomers and astrophysicists use to describe much of their behavior. By unmasking the history behind the search for a real world solution to Einstein’s field equations, Melia offers a first-hand account of an important but untold story. Sometimes dramatic, often exhilarating, but always attuned to the human element, Cracking the Einstein Code is ultimately a showcase of how important science gets done.

"The author, Bengt Beckman, for many years was the head of the cryptanalysis department of the Swedish signal intelligence agency. He has crafted a book that a reader at any level of mathematical sophistication will thoroughly enjoy. It will appeal to a broad audience of readers, from historians and biography buffs to mathematicians to anyone with a passing interest in cryptology and cryptanalysis."--BOOK JACKET.

Everyone is born curious. So, what happens? Why do some people become less curious than others? For individuals, leaders, and companies to be successful, they must determine the things that hold curiosity hostage. Think of the most innovative companies and you will notice they employ people who do not accept the status quo, they aren’t reluctant to change, they evolve with the times, they look for problems to solve, and focus on asking questions. Drawing on decades research and incorporating interviews from some of the top leaders of our time, Hamilton examines the factors that impact curiosity including fear, assumptions, technology, and environment (FATE). Through her ground-breaking research, she has created the Curiosity Code Index (CCI) assessment to determine how these factors have impacted curiosity and to provide an action plan to transform individuals and organizations to help improve areas impacted by curiosity, including innovation, engagement, creativity, and productivity. “I have no special talents. I am only passionately curious” – Albert Einstein

In 1799 Napoleon's army uncovered an ancient stele in the Nile delta. Its inscription, recorded in three distinct scripts--ancient Greek, Coptic, and hieroglyphic--would provide scholars with the first clues to unlocking the secrets of Egyptian hieroglyphs, a language lost for nearly two millennia. More than twenty years later a remarkably gifted Frenchman named Jean-Francois Champollion successfully deciphered the hieroglyphs on the stele, now commonly known as the Rosetta Stone, sparking a revolution in our knowledge of ancient Egypt. Cracking the Egyptian Code is the first biography in English of Champollion, widely regarded as the founder of Egyptology. Andrew Robinson meticulously reconstructs how Champollion cracked the code of the hieroglyphic script, describing how Champollion started with Egyptian obelisks in Rome and papyri in European collections, sailed the Nile for a year, studied the tombs in the Valley of the Kings (a name he first coined), and carefully compared the three scripts on the Rosetta Stone to penetrate the mystery of the hieroglyphic text. Robinson also brings to life the rivalry between Champollion and the English scientist Thomas Young, who claimed credit for launching the decipherment, which Champollion hotly denied. There is much more to Champollion's life than the Rosetta Stone and Robinson gives equal weight to the many roles he played in his tragically brief life, from a teenage professor in Revolutionary France to a supporter of Napoleon (whom he met), an exile, and a curator at the Louvre. Extensively illustrated in color and black-and-white pictures, Cracking the Egyptian Code will appeal to a wide readership interested in Egypt, decipherment and code-breaking, and Napoleon and the French Revolution.

A Best Book of 2021 by Bloomberg BusinessWeek, Time, and The Washington Post The bestselling author of Leonardo da Vinci and Steve Jobs returns with a “compelling” (The Washington Post) account of how Nobel Prize winner Jennifer Doudna and her colleagues launched a revolution that will allow us to cure diseases, fend off viruses, and have healthier babies. When Jennifer Doudna was in sixth grade, she came home one day to find that her dad had left a paperback titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved. When she read it on a rainy Saturday, she discovered she was right, in a way. As she sped through the pages, she became enthralled by the intense drama behind the competition to discover the code of life. Even though her high school counselor told her girls didn’t become scientists, she decided she would. Driven by a passion to understand how nature works and to turn discoveries into inventions, she would help to make what the book’s author, James Watson, told her was the most important biological advance since his codiscovery of the structure of DNA. She and her collaborators turned a curiosity of nature into an invention that will transform the human race: an easy-to-use tool that can edit DNA. Known as CRISPR, it opened a brave new world of medical miracles and moral questions. The development of CRISPR and the race to create vaccines for coronavirus will hasten our transition to the next great innovation revolution. The past half-century has been a digital age, based on the microchip, computer, and internet. Now we are entering a life-science revolution. Children who study digital coding will be joined by those who study genetic code. Should we use our new evolution-hacking powers to make us less susceptible to viruses? What a wonderful boon that would be! And what about preventing depression? Hmmm…Should we allow parents, if they can afford it, to enhance the height or muscles or IQ of their kids? After helping to discover CRISPR, Doudna became a leader in wrestling with these moral issues and, with her collaborator Emmanuelle Charpentier, won the Nobel Prize in 2020. Her story is an “enthralling detective story” (Oprah Daily) that involves the most profound wonders of nature, from the origins of life to the future of our species.
