    Something radically new--an extraordinary rarity in musical culture--it was an instrument that used a genuinely new source of sound: electronics. How this came to be--how an engineering student at Cornell and an avant-garde musician working out of a storefront in California set this revolution in motion--is the story told for the first time in "Analog Days," a book that explores the invention of the synthesizer and its impact on popular culture.The authors take us back to the heady days of the 1960s and early 1970s, when the technology was analog, the synthesizer was an experimental instrument, and synthesizer concerts could and did turn into happenings. Interviews with the pioneers who determined what the synthesizer would be and how it would be used--from inventors Robert Moog and Don Buchla to musicians like Brian Eno, Pete Townshend, and Keith Emerson--recapture their visions of the future of electronic music and a new world of sound.Tracing the development of the Moog synthesizer from its initial conception to its ascension to stardom in "Switched-On Bach," from its contribution to the San Francisco psychedelic sound, to its wholesale adoption by the worlds of film and advertising, "Analog Days" conveys the excitement, uncertainties, and unexpected consequences of a new technology that would provide the soundtrack for a critical chapter of our cultural history.

    This is not a "how-to" book in any sense. Korn wants to get at the why of craft, in particular, and at the satisfactions of creative work, in general to understand their essential nature. How does the making of objects both reflect and refine our own identities? What is it about craft and creative work that makes them so rewarding? What is the nature of those rewards? How do the products of creative work inform society?

    What's the best way to ask someone what their pronouns are? How do you talk about racism with someone who doesn't get it? What is intersectionality anyway, and why do you need to understand it?

     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.

    Much-publicized experiments, often underwritten by Silicon Valley entrepreneurs, have been launched at elite universities and in elementary schools in the poorest neighborhoods. Such was the excitement that, in 2012, the New York Times declared the "year of the MOOC." Less than a decade later, that pronouncement seems premature.In Failure to Disrupt: Why Technology Alone Can't Transform Education, Justin Reich delivers a sobering report card on the latest supposedly transformative educational technologies. Reich takes readers on a tour of MOOCs, autograders, computerized "intelligent tutors," and other educational technologies whose problems and paradoxes have bedeviled educators. Learning technologies--even those that are free to access--often provide the greatest benefit to affluent students and do little to combat growing inequality in education. And institutions and investors often favor programs that scale up quickly, but at the expense of true innovation. It turns out that technology cannot by itself disrupt education or provide shortcuts past the hard road of institutional change.Technology does have a crucial role to play in the future of education, Reich concludes. We still need new teaching tools, and classroom experimentation should be encouraged. But successful reform efforts will focus on incremental improvements, not the next killer app.

     Learn the essential concepts using concrete analogies and vivid diagrams, not mechanical definitions. Calculus isn't a set of rules, it's a specific, practical viewpoint we can apply to everyday thinking. Frustrated With Abstract, Mechanical Lessons? I was too. Despite years of classes, I didn't have a strong understanding of calculus concepts. Sure, I could follow mechanical steps, but I had no lasting intuition. The classes I've seen are too long, taught in the wrong order, and without solid visualizations. Here's how this course is different: 1) It gets to the point. A typical class plods along, saving concepts like Integrals until Week 8. I want to see what calculus can offer by Minute 8. Each compact, tightly-written lesson can be read in 15 minutes. 2) Concepts are taught in their natural order. Most classes begin with the theory of limits, a technical concept discovered 150 years after calculus was invented. That's like putting a new driver into a Formula-1 racecar on day 1. We can begin with the easy-to-grasp concepts discovered 2000 years ago. 3) It has vivid analogies and visualizations. Calculus is usually defined as the "study of change"... which sounds like history or geology. Instead of an abstract definition, we'll see calculus a step-by-step viewpoint to explore patterns. 4) It's written by a human, for humans. I'm not a haughty professor or strict schoolmarm. I'm a friend who saw a fun way to internalize some difficult ideas. This course is a chat over coffee, not a keep-your-butt-in-your-seat lecture. The goal is to help you grasp the Aha! moments behind calculus in hours, not a painful semester (or a decade, in my case). Join Thousands Of Happy Readers Here's a few samples of anonymous feedback as people went through the course. The material covers a variety of levels, whether you're looking for intuitive appreciation or the specifics of the rules. "I've done all of this stuff before, and I do understand calculus intuitively, but this was the most fun I've had going through this kind of thing. The informal writing and multitude of great analogies really helps this become an enjoyable read and the rest is simple after that - you make this seem easy, but at the same time, you aren't doing it for us…This is what math education is supposed to be like :)" "I have psychology and medicine background so I relate your ideas to my world. To me the most useful idea was what each circle production feels like. Rings are natural growth…Slices are automatable chunks and automation cheapens production… Boards in the shape on an Arch are psychologically most palatable for work (wind up, hard part, home stretch). Brilliant and kudos, from one INTP to another." "I like how you're introducing both derivatives and integrals at the same time - it's really helps with understanding the relationship between them. Also, I appreciate how you're coming from such a different angle than is traditionally taken - it's always interesting to see where you decide to go next." "That was breathtaking. Seriously, mail my air back please, I've grown used to it. Beautiful work, thank you. Lesson 15 was masterful. I am starting to feel calculus. "d/dx is good" (sorry, couldn't resist!)."
