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.

Inspired by the best-selling novel "The Da Vinci Code," this imaginative cross-curricular resource is the perfect way to reinforce basic math skills as well as introduce the study of great "thinkers" to your class. A short biography is included for each featured "thinker" that contains secret, embedded information. Students must study the biography and crack the code to answer a set of worksheet questions. It is within these hidden codes that students will practice fractions, geometry. place value, and a variety of other valuable math skills.

A lost cipher. A race against time to decode it. Marine archaeologists Kate Wetherall and Lou Bates are diving off Howland Island in the middle of the Pacific Ocean, when a torpedo-shaped object hurtles through the water towards them; the fuselage of Amelia Earhart's lost plane. In the cockpit, they find a corroded metal cylinder the size of a baton. Landing back on US soil, Kate and Lou are arrested and interrogated by special forces, and the cylinder confiscated. Behind the arrests is Glena Buckingham, CEO of the powerful energy conglomerate Eurenergy, as she too has discovered that the wrecked plane may have held precious secret cargo. Meanwhile, an extraordinary piece of footage has come to light - of Einstein talking about a radical new defence technology he had been working on. Whoever can decrypt the lost cipher, which holds the key to Einstein's secret defence technology, could hold the key to global power.

" This is one of the most important books on quantum mechanics ever written for lay readers, in which an eminent physicist and successful science writer, Heinz Pagels, discusses and explains the core concepts of physics without resorting to complicated mathematics. "Can be read by anyone. I heartily recommend it!" -- New York Times Book Review. 1982 edition"--

Princeton, New Jersey, 1951: As a CIA operative watches from the shadows, two old men—Israeli prime minister David Ben-Gurion and world-renowned scientist Albert Einstein—enter Einstein’s home to speak privately about nuclear weapons and the existence of God. Present Day Cairo, Egypt: Over lunch in the Muslim quarter, world-famous cryptanalyst Thomas Noronha is hired by a beautiful dark-haired woman, Ariana Pakravan, to decipher a cryptogram hidden in a recently discovered secret document under heavy security in Tehran. A manuscript penned by Albert Einstein, it is titled Die Gottesformel: The God Formula. So begins a remarkable adventure that spans the world, as Thomas and Ariana pursue the dangerous truth behind an incredible document. The Einstein Enigma is a breathtaking fusion of science, thriller, and religion, a mind-bending trip to the source of time, the essence of the universe, and the meaning of life itself.

What do Stone Age axes, Toll House cookies, and Burning Man have in common? They are all examples of code in action. What is "code"? Code is the DNA of human civilization as it has evolved from Neolithic simplicity to modern complexity. It is the "how" of progress. It is how ideas become things, how ingredients become cookies. It is how cities are created and how industries develop. In a sweeping narrative that takes readers from the invention of the alphabet to the advent of the Blockchain, Philip Auerswald argues that the advance of code is the key driver of human history. Over the span of centuries, each major stage in the advance of code has brought a shift in the structure of society that has challenged human beings to reinvent not only how we work but who we are. We are in another of those stages now. The Code Economy explains how the advance of code is once again fundamentally altering the nature of work and the human experience. Auerswald provides a timely investigation of value creation in the contemporary economy-and an indispensable guide to our economic future.
