A New Kind of Science


Stephen Wolfram - 1997
    Wolfram lets the world see his work in A New Kind of Science, a gorgeous, 1,280-page tome more than a decade in the making. With patience, insight, and self-confidence to spare, Wolfram outlines a fundamental new way of modeling complex systems. On the frontier of complexity science since he was a boy, Wolfram is a champion of cellular automata--256 "programs" governed by simple nonmathematical rules. He points out that even the most complex equations fail to accurately model biological systems, but the simplest cellular automata can produce results straight out of nature--tree branches, stream eddies, and leopard spots, for instance. The graphics in A New Kind of Science show striking resemblance to the patterns we see in nature every day. Wolfram wrote the book in a distinct style meant to make it easy to read, even for nontechies; a basic familiarity with logic is helpful but not essential. Readers will find themselves swept away by the elegant simplicity of Wolfram's ideas and the accidental artistry of the cellular automaton models. Whether or not Wolfram's revolution ultimately gives us the keys to the universe, his new science is absolutely awe-inspiring. --Therese Littleton

The Holocaust: The Human Tragedy


Martin Gilbert - 2014
       Rich with eyewitness accounts, incisive interviews, and first-hand source materials—including documentation from the Eichmann and Nuremberg war crime trials—this sweeping narrative begins with an in-depth historical analysis of the origins of anti-Semitism in Europe, and tracks the systematic brutality of Hitler’s “Final Solution” in unflinching detail. It brings to light new source materials documenting Mengele’s diabolical concentration camp experiments and documents the activities of Himmler, Eichmann, and other Nazi leaders. It also demonstrates comprehensive evidence of Jewish resistance and the heroic efforts of Gentiles to aid and shelter Jews and others targeted for extermination, even at the risk of their own lives.   Combining survivor testimonies, deft historical analysis, and painstaking research, The Holocaust is without doubt a masterwork of World War II history.   “A fascinating work that overwhelms us with its truth . . . This book must be read and reread.” —Elie Wiesel, Nobel Peace Prizing–winning author of Night

Seeing Further: Ideas, Endeavours, Discoveries and Disputes — The Story of Science Through 350 Years of the Royal Society


Bill BrysonJohn D. Barrow - 2010
    A twenty-eight year old — and not widely famous — Christopher Wren was giving a lecture on astronomy. As his audience listened to him speak, they decided that it would be a good idea to create a Society to promote the accumulation of useful knowledge.With that, the Royal Society was born. Since its birth, the Royal Society has pioneered scientific exploration and discovery. Isaac Newton, Charles Darwin, Albert Einstein, Robert Hooke, Robert Boyle, Joseph Banks, Humphry Davy, Isambard Kingdom Brunel, John Locke, Alexander Fleming — all were fellows.Bill Bryson’s favourite fellow was Reverend Thomas Bayes, a brilliant mathematician who devised Bayes’ theorem. Its complexity meant that it had little practical use in Bayes’ own lifetime, but today his theorem is used for weather forecasting, astrophysics and stock market analysis. A milestone in mathematical history, it only exists because the Royal Society decided to preserve it — just in case. The Royal Society continues to do today what it set out to do all those years ago. Its members have split the atom, discovered the double helix, the electron, the computer and the World Wide Web. Truly international in its outlook, it has created modern science.Seeing Further celebrates its momentous history and achievements, bringing together the very best of science writing. Filled with illustrations of treasures from the Society’s archives, this is a unique, ground-breaking and beautiful volume, and a suitable reflection of the immense achievements of science.

Male vs. Man: How to Honor Women, Teach Children, and Elevate Men to Change the World


Dondré T. Whitfield - 2020
    Men look to be of service. Emmy Award–nominated actor best known for his role on Queen Sugar and transformational speaker Dondré Whitfield challenges us to be real men in this provocative look at the power found in serving others.Too many males abuse the power they have.Often those males grow up without healthy role models and so, while they look like men, they act like boys. Only now there are adult consequences to their actions.And many of us are caught in the shifting cultural ideas about manhood, unsure of how to make sound decisions or truly be a man. Every day we find evidence that the role of men at home, at work, and out in the world is deeply misinterpreted.In Male vs. Man, Dondré Whitfield equips us to become men rather than simply "grown males." Men are healthy and productive servant-leaders who bring positive change to their communities. Males are self-serving and stuck in negative cycles that we hear and read about daily. They create chaos instead of cultivating calm.Male vs. Man is an uplifting playbook for men who want to level up. It will help men and women alike understand what real manhood is, based on biblical wisdom as well as hard-earned lessons from someone who has been there. With practical guidance and a strong spiritual foundation, Dondré shows how to cultivate the life-changing spiritual, emotional, and psychological attributes of servant leadership at home, at work, and in our communities.

Essays on the Theory of Numbers


Richard Dedekind - 1901
    W. R. Dedekind. The first presents Dedekind's theory of the irrational number-the Dedekind cut idea-perhaps the most famous of several such theories created in the 19th century to give a precise meaning to irrational numbers, which had been used on an intuitive basis since Greek times. This paper provided a purely arithmetic and perfectly rigorous foundation for the irrational numbers and thereby a rigorous meaning of continuity in analysis.The second essay is an attempt to give a logical basis for transfinite numbers and properties of the natural numbers. It examines the notion of natural numbers, the distinction between finite and transfinite (infinite) whole numbers, and the logical validity of the type of proof called mathematical or complete induction.The contents of these essays belong to the foundations of mathematics and will be welcomed by those who are prepared to look into the somewhat subtle meanings of the elements of our number system. As a major work of an important mathematician, the book deserves a place in the personal library of every practicing mathematician and every teacher and historian of mathematics. Authorized translations by "Vooster " V. Beman.

A More Perfect Heaven: How Copernicus Revolutionized the Cosmos


Dava Sobel - 2011
    Over the next two decades, Copernicus expanded his theory through hundreds of observations, while compiling in secret a book-length manuscript that tantalized mathematicians and scientists throughout Europe. For fear of ridicule, he refused to publish.In 1539, a young German mathematician, Georg Joachim Rheticus, drawn by rumors of a revolution to rival the religious upheaval of Martin Luther's Reformation, traveled to Poland to seek out Copernicus. Two years later, the Protestant youth took leave of his aging Catholic mentor and arranged to have Copernicus's manuscript published, in 1543, as De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres)-the book that forever changed humankind's place in the universe.In her elegant, compelling style, Dava Sobel chronicles, as nobody has, the conflicting personalities and extraordinary discoveries that shaped the Copernican Revolution. At the heart of the book is her play And the Sun Stood Still, imagining Rheticus's struggle to convince Copernicus to let his manuscript see the light of day. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of narration, giving us an unforgettable portrait of scientific achievement, and of the ever-present tensions between science and faith.

Mental Math: Tricks To Become A Human Calculator


Abhishek V.R. - 2017
    Just read this till the end You don’t have to buy this book. Just read this till end & you will learn something that will change the way you do math forever. Warning: I am revealing this secret only to the first set of readers who will buy this book & plan to put this secret back inside the book once I have enough sales. So read this until the very end while you still can.School taught you the wrong way to do mathThe way you were taught to do math, uses a lot of working memory. Working memory is the short term memory used to complete a mental task. You struggle because trying to do mental math the way you were taught in school, overloads your working memory. Let me show you what I mean with an example:Try to multiply the 73201 x 3. To do this you multiply the following:1 x 3 =0 x 3 =2 x 3 =3 x 3 =7 x 3 =This wasn’t hard, & it might have taken you just seconds to multiply the individual numbers. However, to get the final answer, you need to remember every single digit you calculated to put them back together. It takes effort to get the answer because you spend time trying to recall the numbers you already calculated. Math would be easier to do in your head if you didn’t have to remember so many numbers. Imagine when you tried to multiply 73201 x 3, if you could have come up with the answer, in the time it took you to multiply the individual numbers. Wouldn’t you have solved the problem faster than the time it would have taken you to punch in the numbers inside a calculator? Do the opposite of what you were taught in schoolThe secret of doing mental math is to calculate from left to right instead of from right to left. This is the opposite of what you were taught in school. This works so well because it frees your working memory almost completely. It is called the LR Method where LR stands for Left to Right.Lets try to do the earlier example where we multiplied 73201 x 3. This time multiply from left to right, so we get:7 x 3 = 213 x 3 = 93 x 2 = 60 x 3 = 03 x 1 = 3Notice that you started to call out the answer before you even finished the whole multiplication problem. You don’t have to remember a thing to recall & use later. So you end up doing math a lot faster. The Smart ChoiceYou could use what you learnt & apply it to solve math in the future. This might not be easy, because we just scratched the surface. I've already done the work for you. Why try to reinvent the wheel, when there is already a proven & tested system you can immediately apply. This book was first available in video format & has helped 10,000+ students from 132 countries. It is available at ofpad.com/mathcourse to enroll. This book was written to reach students who consume the information in text format. You can use the simple techniques in this book to do math faster than a calculator effortlessly in your head, even if you have no aptitude for math to begin with.Imagine waking up tomorrow being able to do lightning fast math in your head. Your family & friends will look at you like you are some kind of a genius. Since calculations are done in your head, you will acquire better mental habits in the process. So you will not just look like a genius. You will actually be one.

The Written World: The Power of Stories to Shape People, History, Civilization


Martin Puchner - 2014
    Puchner introduces us to numerous visionaries as he explores sixteen foundational texts selected from more than four thousand years of world literature and reveals how writing has inspired the rise and fall of empires and nations, the spark of philosophical and political ideas, and the birth of religious beliefs. Indeed, literature has touched the lives of generations and changed the course of history.At the heart of this book are works, some long-lost and rediscovered, that have shaped civilization: the first written masterpiece, the Epic of Gilgamesh; Ezra’s Hebrew Bible, created as scripture; the teachings of Buddha, Confucius, Socrates, and Jesus; and the first great novel in world literature, The Tale of Genji, written by a Japanese woman known as Murasaki. Visiting Baghdad, Puchner tells of Scheherazade and the stories of One Thousand and One Nights, and in the Americas we watch the astonishing survival of the Maya epic Popol Vuh. Cervantes, who invented the modern novel, battles pirates both real (when he is taken prisoner) and literary (when a fake sequel to Don Quixote is published). We learn of Benjamin Franklin’s pioneering work as a media entrepreneur, watch Goethe discover world literature in Sicily, and follow the rise in influence of The Communist Manifesto. We visit Troy, Pergamum, and China, and we speak with Nobel laureates Derek Walcott in the Caribbean and Orhan Pamuk in Istanbul, as well as the wordsmiths of the oral epic Sunjata in West Africa.Throughout The Written World, Puchner’s delightful narrative also chronicles the inventions—writing technologies, the printing press, the book itself—that have shaped religion, politics, commerce, people, and history. In a book that Elaine Scarry has praised as “unique and spellbinding,” Puchner shows how literature turned our planet into a written world.

To Explain the World: The Discovery of Modern Science


Steven Weinberg - 2015
    He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world—they did not understand what there is to understand, or how to understand it. Yet over the centuries, through the struggle to solve such mysteries as the curious backward movement of the planets and the rise and fall of the tides, the modern discipline of science eventually emerged. Along the way, Weinberg examines historic clashes and collaborations between science and the competing spheres of religion, technology, poetry, mathematics, and philosophy.An illuminating exploration of the way we consider and analyze the world around us, To Explain the World is a sweeping, ambitious account of how difficult it was to discover the goals and methods of modern science, and the impact of this discovery on human knowledge and development.
