Book Description
The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science. Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions. The single most important skill for a computer scientist is problem solving. Problem solving means the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately. As it turns out, the process of learning to program is an excellent opportunity to practice problem-solving skills. That's why this chapter is called, The way of the program. On one level, you will be learning to program, a useful skill by itself. On another level, you will use programming as a means to an end. As we go along, that end will become clearer.

Book Description
#1 NEW YORK TIMES BESTSELLER • NAACP IMAGE AWARD WINNER • A dramatic expansion of a groundbreaking work of journalism, The 1619 Project: A New Origin Story offers a profoundly revealing vision of the American past and present. “[A] groundbreaking compendium . . . bracing and urgent . . . This collection is an extraordinary update to an ongoing project of vital truth-telling.”—Esquire NOW AN EMMY-NOMINATED HULU ORIGINAL DOCUSERIES • FINALIST FOR THE KIRKUS PRIZE • ONE OF THE BEST BOOKS OF THE YEAR: The Washington Post, NPR, Esquire, Marie Claire, Electric Lit, Ms. magazine, Kirkus Reviews, Booklist In late August 1619, a ship arrived in the British colony of Virginia bearing a cargo of twenty to thirty enslaved people from Africa. Their arrival led to the barbaric and unprecedented system of American chattel slavery that would last for the next 250 years. This is sometimes referred to as the country’s original sin, but it is more than that: It is the source of so much that still defines the United States. The New York Times Magazine’s award-winning 1619 Project issue reframed our understanding of American history by placing slavery and its continuing legacy at the center of our national narrative. This book substantially expands on that work, weaving together eighteen essays that explore the legacy of slavery in present-day America with thirty-six poems and works of fiction that illuminate key moments of oppression, struggle, and resistance. The essays show how the inheritance of 1619 reaches into every part of contemporary American society, from politics, music, diet, traffic, and citizenship to capitalism, religion, and our democracy itself. This book that speaks directly to our current moment, contextualizing the systems of race and caste within which we operate today. It reveals long-glossed-over truths around our nation’s founding and construction—and the way that the legacy of slavery did not end with emancipation, but continues to shape contemporary American life.

Book Description
"Nuclear weapons, since their conception, have been the subject of secrecy. In the months after the dropping of the atomic bombs on Hiroshima and Nagasaki, the American scientific establishment, the American government, and the American public all wrestled with what was called the "problem of secrecy," wondering not only whether secrecy was appropriate and effective as a means of controlling this new technology but also whether it was compatible with the country's core values. Out of a messy context of propaganda, confusion, spy scares, and the grave counsel of competing groups of scientists, what historian Alex Wellerstein calls a "new regime of secrecy" was put into place. It was unlike any other previous or since. Nuclear secrets were given their own unique legal designation in American law ("restricted data"), one that operates differently than all other forms of national security classification and exists to this day. Drawing on massive amounts of declassified files, including records released by the government for the first time at the author's request, Restricted Data is a narrative account of nuclear secrecy and the tensions and uncertainty that built as the Cold War continued. In the US, both science and democracy are pitted against nuclear secrecy, and this makes its history uniquely compelling and timely"--

Book Description
The existence Moses as well as the Exodus is a crucial question because, according to the Bible, the character related to that famous event forms the basis of the Passover which meant the Promised Land for Jews and later the Paradise for Christians. However, according to most Egyptologists, there is absolutely no evidence of Moses and the Exodus in Egyptian documents, which leads them to conclude that the whole biblical story is a myth written for gullible people. However, according to Egyptian accounts the last king of the 15th dynasty named Apopi, “very pretty”, which was Moses' birth name (Ex 2:2), reigned 40 years in Egypt (1613-1573) and met Seqenenre Taa, 40 years later, the last pharaoh of the 17th dynasty who died in May 1533 BCE in dramatic and unclear circumstances (Ps 136:15). The state of his mummy proves that his body received severe injuries and remained abandoned for several days before being mummified. The eldest son of Seqenenre Taa, Ahmose Sapaïr, who was crown prince died in a dramatic and unexplained way shortly before his father (Ex 12:29). Prince Kamose, Seqenenre Taa's brother, assured interim of authority for 3 years and threatened attack the former pharaoh Apopi, new prince of Retenu (Palestine) who took the name Moses, according to Manetho, an Egyptian priest and historian. In the stele of the Tempest, Kamose also blames Apopi for all the disasters that come to fall upon Egypt, which caused many deaths. Ironically, those who believe Egyptologists are actually the real gullible ones
