An introduction to dimensional analysis, a method of scientific analysis used to investigate and simplify complex physical phenomena, demonstrated through a series of engaging examples. This book offers an introduction to dimensional analysis, a powerful method of scientific analysis used to investigate and simplify complex physical phenomena. The method enables bold approximations and the generation of testable hypotheses. The book explains these analyses through a series of entertaining applications; students will learn to analyze, for example, the limits of world-record weight lifters, the distance an electric submarine can travel, how an upside-down pendulum is similar to a running velociraptor, and the number of Olympic rowers required to double boat speed. The book introduces the approach through easy-to-follow, step-by-step methods that show how to identify the essential variables describing a complex problem; explore the dimensions of the problem and recast it to reduce complexity; leverage physical insights and experimental observations to further reduce complexity; form testable scientific hypotheses; combine experiments and analysis to solve a problem; and collapse and present experimental measurements in a compact form. Each chapter ends with a summary and problems for students to solve. Taken together, the analyses and examples demonstrate the value of dimensional analysis and provide guidance on how to combine and enhance dimensional analysis with physical insights. The book can be used by undergraduate students in physics, engineering, chemistry, biology, sports science, and astronomy.

Everything you've always wanted to know about self-driving cars, Netflix recommendations, IBM's Watson, and video game-playing computer programs. The future is here: Self-driving cars are on the streets, an algorithm gives you movie and TV recommendations, IBM's Watson triumphed on Jeopardy over puny human brains, computer programs can be trained to play Atari games. But how do all these things work? In this book, Sean Gerrish offers an engaging and accessible overview of the breakthroughs in artificial intelligence and machine learning that have made today's machines so smart. Gerrish outlines some of the key ideas that enable intelligent machines to perceive and interact with the world. He describes the software architecture that allows self-driving cars to stay on the road and to navigate crowded urban environments; the million-dollar Netflix competition for a better recommendation engine (which had an unexpected ending); and how programmers trained computers to perform certain behaviors by offering them treats, as if they were training a dog. He explains how artificial neural networks enable computers to perceive the world-and to play Atari video games better than humans. He explains Watson's famous victory on Jeopardy, and he looks at how computers play games, describing AlphaGo and Deep Blue, which beat reigning world champions at the strategy games of Go and chess. Computers have not yet mastered everything, however; Gerrish outlines the difficulties in creating intelligent agents that can successfully play video games like StarCraft that have evaded solution-at least for now. Gerrish weaves the stories behind these breakthroughs into the narrative, introducing readers to many of the researchers involved, and keeping technical details to a minimum. Science and technology buffs will find this book an essential guide to a future in which machines can outsmart people.

Die vollstandige Berechnung und Darstellung von Schallvorgangen macht schon in den Fallen, wo es sich im einfaohe Strahleranordnungen handelt, nicht unerhebliche Schwierigkeiten. Damit hangt es wohl zu- sammen, dass eine systematische Behandlung daruber nicht vorliegt. Im folgenden wird der Versuch gemacht, die grundlegenden Formeln und Begriffe zu entwickeln und an einer Reihe von einfachen Beispielen praktisch anzuwenden. Dabei erscheint es wegen der ausserordentlichen Vereinfaohung naturgemass, die Berechnung zunachst auf das Gebiet in grosser Entfernung vom Strahler zu beschranken. Bei dieser Ein- schrankung ergibt sich der UEbergang vom ungerichteten zum gerichteten Strahler sehr einfach, indem die Formeln des ungerichteten Schall- senders durch einen zusatzlichen Faktor, der als Richtfaktor bzw. Strah- lungsfaktor gekennzeichnet ist, erganzt werden. Auch maoht dann die Berechnung des Sohallfeldes von solchen Membranen, die im Gegensatz zur Kolbenmembran keine konstante Sohwingungsamplitude hab:: m oder Knotenlinien besitzen, keine besonderen Schwierigkeiten. Der zweite Teil behandelt die Darstellung des in unmittelbarer Nahe des Strahlers vorhandenen Schallfeldes. Der zunachst untersuchte Fall von zwei punktfoermigen Strahlern zeigt bereits, dass jetzt ganz wesent- lich kompliziertere Verhaltnisse vorliegen. Man ist daher auch ge- zwungen, das Schallfeld an jeder Stelle zu beschreiben. Das geschieht am einfachsten, indem man die Kurven zeichnet, fur welche die Druck- amplitude einen konstanten Wert besitzt. Oft ist es jedoch auch zweck- voll, Kurven konstanter Phase zu berechnen. Im Falle der kreisfoermigen Kolbenmembran, der praktisch von besonderer Bedeutung ist, ist es wesentlich, dass wenigstens die Werte auf der Mittelachse, auch in in- mittelbarer Nahe, sehr einfach angegeben werden koennen.
