This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    Graphs are not included, but both the graphs and the concepts behind them are explained; only basic math is included, and you can even skim over the math and still come away with an understanding of the concepts; statistics is not included at all.BASIC ECONOMICS FOR STUDENTS AND NON-STUDENTS ALIKE is an easy way to learn concepts relating to economics and the economy. It is a product of thousands of hours spent online, teaching basic concepts in economics to hundreds of students worldwide over the course of the past several years. From back and forth communications, I have discovered the explanations for the concepts that students find easiest to understand, as well as the areas that most often get misunderstood and under-emphasized.I have worked with students located throughout the United States and from many different countries, on six different continents; students from many different school systems with different points of emphasis; students with different levels of knowledge, different backgrounds, and different levels of interest in the subject. I have received numerous comments and testimonials regarding the teaching methods that I incorporate in BASIC ECONOMICS FOR STUDENTS AND NON-STUDENTS ALIKE.The subject matter included in BASIC ECONOMICS FOR STUDENTS AND NON-STUDENTS ALIKE comes from a compilation of many different textbooks at the introductory and intermediate levels. My goal was to include every subject in economics that normally will be found in an introductory level textbook of economics, microeconomics, or macroeconomics. Since different school systems, different classroom instructors, and different textbooks cover a slightly different combination of topics, BASIC ECONOMICS FOR STUDENTS AND NON-STUDENTS ALIKE is a little more comprehensive than most single introductory textbooks of economics. Some of the topics will be found in introductory classes in some schools, but in intermediate-level classes in other schools.

    The germ revolution came after two decades of scientific virtuosity, outstanding feats of intellectual courage and bitter personal rivalries, doctors at last recognised that infectious diseases are caused by mircoscopic organisms.

    The producers refused. In Doctor Who, the Twelfth Doctor's costume was inspired by David Bowie. In Game of Thrones, Hodor's real name is Wyllis. Matthew Perry plays Chandler in Friends. He says he can't remember a single thing from the show throughout three seasons. In The Simpsons, Hans Moleman has died at least 15 times. Many mobsters contacted James Gandolfini to tell him his performance was excellent in The Sopranos but warned him not to wear shorts in the show. Millie Bobby Brown was 11 when she was cast as Eleven in Stranger Things. The Tourette Syndrome Association praised the show, South Park, for its accurate portrayal of the Tourette's condition. In Family Guy, Meg's full name is Megatron Griffin.

    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    Maybe your teacher took the controversial stand that the Civil War was all about states’ rights… or maybe you learned all about the horrors slavery, but never quite figured out why things didn’t get better after the war ended. If you didn’t go to school in the United States, things are even more confusing. When the media is full of references to the Confederate flag, the legacy of slavery, and poverty in the American South, you might have a vague sense that things are bad because of the Civil War… but why? Why does a war that happened over a hundred and fifty years ago still cast a shadow over the United States? This book will tell you why. It will lead you, step-by-step, through the causes of the Civil War, and the effects. But unlike your high school history teacher, it won’t put you to sleep with long-winded biographies and lists of dates. The names you’ll learn are the big players, the ones with big personalities, who made big differences. In just a few minutes a day, you can read bite-sized stories from the Civil War – quick, easy explanations to guide you through the main points, with just enough scary, surprising, or just plain strange facts to keep you coming back for more. Each chapter ends with a bonus helping of trivia and some quick questions to test your knowledge. By the time you’re finished, you’ll know all the facts your history teacher never taught you – from who said slavery was a “positive good” (and why they thought that), to who dressed up in women’s clothing to escape from Union soldiers.

    Over five decades, Star Trek's celebration of mankind's technical achievements and positive view of the future have earned it an enduring place in our global culture. Its scientific vision has also had a profound effect on the past thirty years of technological breakthroughs. Join William Shatner, the original captain of the Starship Enterprise, as he reveals how Star Trek has influenced and inspired some of our greatest scientific minds -- the people behind the future we will all share. In interviews with dozens of scientists we learn about the inventions that will revolutionise our lives and the discoveries that will make it truly possible to explore the last great frontier -- space. As one Nobel Laureate commented on being shown a wood and plastic model of the engine core from a Star Trek: The Next Generation starship: I'm working on that. From the technicalities of warp speed to real-life replicators to the likelihood of our being able to beam across continents, this always-informative book takes us on a fascinating and eye-opening voyage to

    But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list.  Maxwell, an unassuming Victorian Scotsman, explained how we perceive colour. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.   Along the way, he set up one of the most enduring challenges in physics, one that has taxed the best minds ever since. ‘Maxwell’s demon’ is a tiny but thoroughly disruptive thought experiment that suggests the second law of thermodynamics, the law that governs the flow of time itself, can be broken. This is the story of a groundbreaking scientist, a great contributor to our understanding of the way the world works, and his duplicitous demon.

    

    We currently see no evidence of any kind indicating that extraterrestrials exist outside of our solar system. But at this moment, millions of engineers, scientists, corporations, universities and entrepreneurs are racing to create the second intelligent species right here on planet earth. And we can see the second intelligent species coming from all directions in the form of self-driving cars, automated call centers, chess-playing and Jeopardy-playing computers that beat all human players, airport kiosks, restaurant tablet systems, etc. The frightening thing is that these robots will soon be eliminating human jobs in startling numbers. The first wave of unemployed workers is likely to be a million truck drivers who are replaced by self-driving trucks. Pilots will be eliminated soon as well. Then, as new computer vision systems come online, we will see tens of millions of workers in retail stores, fast food restaurants and construction sites replaced by robots. Unless we take steps now to change the economy, we will soon have tens of millions of workers who are unemployed and seeking welfare because they will have no other choice. Marshall Brain's new book "The Second Intelligent Species: How Humans Will Become as Irrelevant as Cockroaches" explores how the future will unfold as the second intelligent species emerges. The book answers questions like: - How will new computer vision systems affect the job market? - How many people will become unemployed by the second intelligent species? - What will happen to millions of newly unemployed workers? - How can modern society and modern economies cope with run-away unemployment caused by robots? - What will happen when the first sentient, conscious computer appears? - What moral and ethical principles will guide the second intelligent species? - Why do we see no extraterrestrials in our universe? "The Second Intelligent Species" offers a unique and fascinating look at the future of the human race, and the choices we will need to make to avoid massive unemployment and poverty worldwide as intelligent machines start eliminating millions of jobs.

    Just a half century ago, this idea was revolutionary. In April 1953, James Watson and Francis Crick published in Nature their groundbreaking work revealing the double helix structure of DNA. While this discovery received wide attention from both mainstream media and the academic community, it was just one part of the bigger story in this history of molecular biology. By the mid-1950s, the scientific community confirmed that genes were indeed comprised of DNA; they just needed to crack the genetic code—and the race was on. Life’s Greatest Secret is the full and rich history of this challenge and the characters—many of whom were not biologists—whose work contributed to this grand scientific endeavor: mathematician and father of cybernetics Norbert Wiener, physicist Erwin Schrödinger, information theorist Claude Shannon, and biologists Jacques Monod and Marshall Nirenberg.In Life’s Greatest Secret, science historian and zoologist Matthew Cobb shows that the race to crack the genetic code was mostly a matter of craft—individuals or small groups struggling with ideas and concepts as much as they were with facts, trying to find the right experiment to answer the right questions, even if they didn’t know what the questions were, and finding that, even when the most definitive answer served mostly to reveal more ignorance, whether in 1953, with Watson and Crick, or in 1961, when Nirenberg and Matthaei showed how DNA codes for specific amino acids, and again and again thereafter, or in 2000, with the first publication of a human genome. Each discovery was a leap forward in our understanding of the natural world and our place within in, akin to the discoveries of Galileo and Einstein in the realm of physics, or the publication of Darwin’s On the Origin of Species. And each served to show how much bigger the problem was that anyone had previously imagined, a trend that continues, as Cobb shows, even today, whether we are discussing gene regulation, epigenetics, or GMOs.Life’s Greatest Secret is a story of ideas and of experimentation, of ingenuity, insight, and dead-ends, in the hunt to make the greatest discovery of twentieth century biology. Ultimately, though, this is a story of humans exploring what it is that makes us human.
