Book Description
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.

Book Description
What is space? What is time? Where did the universe come from? The answers to mankind's most enduring questions may lie in science's greatest enigma: black holes. A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. This can occur when a star approaches the end of its life. Unable to generate enough heat to maintain its outer layers, it shrinks catastrophically down to an infinitely dense point. When this phenomenon was first proposed in 1916, it defied scientific understanding so much that Albert Einstein dismissed it as too ridiculous to be true. But scientists have since proven otherwise. In 1971, Paul Murdin and Louise Webster discovered the first black hole: Cygnus X-1. Later, in the 1990s, astronomers using NASA's Hubble Space Telescope found that not only do black holes exist, supermassive black holes lie at the heart of almost every galaxy, including our own. It would take another three decades to confirm this phenomenon. On 10 April 2019, a team of astronomers made history by producing the first image of a black hole. A Crack in Everything is the story of how black holes came in from the cold and took cosmic centre stage. As a journalist, Marcus Chown interviews many of the scientists who made the key discoveries, and, as a former physicist, he translates the most esoteric of science into everyday language. The result is a uniquely engaging page-turner that tells one of the great untold stories in modern science.

Book Description
An epidemic such as COVID-19 challenges life’s very order and meaning, interferes in our relations with others, and breaks apart our routine. It raises many questions in the realms of ethics, politics, theology, psychology, and beyond. Perhaps more than anything else, it prompts us to ponder: what does this encounter with widespread anguish and distress imply about the human self-perception as sovereign rulers of Earthly life? In this book, renowned thinker Avi Sagi explores the existential matters brought to the philosophical fore by the pandemic. He shows how we, when thrown into the terror of a crisis, carry the traditions, values, ideals, hopes, failures, and habits that constitute our lives, all shaping the way we grapple with questions seemingly resolved. We may then find that the crack that opens up at times of sorrow can also be a moment of discovery. Sagi analyzes various ways of confronting the crack now at the heart of our existence. What emerges is a clear normative statement: We are not only what we were but also what we can be, and we can create a world of meaning by standing together with others.

Press your chin hard against your throat. Now turn your head to the left and lift your left shoulder until it touches your ear. Keep your chin against your throat, your left ear against your left shoulder, contract your neck and shoulder muscles as tightly as you can and hold it like that for the rest of your life. That’s right. Eat like that, brush your teeth like that, drive like that and keep your head like that when you go to sleep at night. This is what psychiatrists in South Africa did to me and they expect me to live like that for the rest of my life.

When growth requires the baptism of blood, when a road requires the accumulation of bones, when a grain of sand can shake the heavens, when a drop of water can water the earth... When a person lifted his hand to pick up the stars, the sun and moon, or the rivers and mountains with his hands covered ... In this era where all races coexist, the legend had been erased from history. At the limit of a certain period, the legend of the Ji Realm had been opened ... In this life, a young man covered in blood crawled out of the Blood Cauldron. A story of exploration, conquest, slaughter, rise to prominence, hot-blooded, and a lone emperor began to play out ... The survival of the apocalypse, the vicissitudes of life, the struggles in battle, the emotions between life and death... The world was sad, but it was also boiling. When the myth finally lifted the veil of mystery, was it as perfect as you thought it was?
