This book examines the huge scope of mathematical areas explored and developed by Euler, which includes number theory, combinatorics, geometry, complex variables and many more. The information known to Euler over 300 years ago is discussed, and many of his advances are reconstructed. Readers will be left in no doubt about the brilliance and pervasive influence of Euler's work.

     They are also used in countless industries such as medicine, manufacturing and finance to help companies make better decisions and reduce risk. Whether coded or scratched out by hand, both algorithms are powerful tools that can make a significant impact. This book is a visual introduction for beginners that unpacks the fundamentals of decision trees and random forests. If you want to dig into the basics with a visual twist plus create your own machine learning algorithms in Python, this book is for you.

    Information is provided on the fundamental concepts of table and graph design, the numbers and knowledge most suitable for display in a graphic form, the best tabular means to communicate certain ideas, and the component-level aspects of design. Analysts, technicians, and managers will appreciate the solid theory behind this outline for ensuring that tables and graphs present quantitative business information in a truthful, attractive format that facilitates better decision making.

    At the time we were hoping that our approach of writing a book which would be both accessible without mathematical sophistication and portray these exiting new fields in an authentic manner would find an audience. Now we know it did. We know from many reviews and personal letters that the book is used in a wide range of ways: researchers use it to acquaint themselves, teachers use it in college and university courses, students use it for background reading, and there is also a substantial audience of lay people who just want to know what chaos and fractals are about. Every book that is somewhat technical in nature is likely to have a number of misprints and errors in its first edition. Some of these were caught and brought to our attention by our readers. One of them, Hermann Flaschka, deserves to be thanked in particular for his suggestions and improvements. This second edition has several changes. We have taken out the two appendices from the firstedition. At the time of the first edition Yuval Fishers contribution, which we published as an appendix was probably the first complete expository account on fractal image compression. Meanwhile, Yuvals book Fractal Image Compression: Theory and Application appeared and is now the publication to refer to.

    If you use Python, even as a beginner, this book will teach you practical ways to build your own machine learning solutions. With all the data available today, machine learning applications are limited only by your imagination.You'll learn the steps necessary to create a successful machine-learning application with Python and the scikit-learn library. Authors Andreas Muller and Sarah Guido focus on the practical aspects of using machine learning algorithms, rather than the math behind them. Familiarity with the NumPy and matplotlib libraries will help you get even more from this book.With this book, you'll learn:Fundamental concepts and applications of machine learningAdvantages and shortcomings of widely used machine learning algorithmsHow to represent data processed by machine learning, including which data aspects to focus onAdvanced methods for model evaluation and parameter tuningThe concept of pipelines for chaining models and encapsulating your workflowMethods for working with text data, including text-specific processing techniquesSuggestions for improving your machine learning and data science skills

If you're interested in developing web applications, analyzing multilingual news sources, or documenting endangered languages -- or if you're simply curious to have a programmer's perspective on how human language works -- you'll find Natural Language Processing with Python both fascinating and immensely useful.

    This connectedness is found in many incarnations: in the rapid growth of the Internet, in the ease with which global communication takes place, and in the ability of news and information as well as epidemics and financial crises to spread with surprising speed and intensity. These are phenomena that involve networks, incentives, and the aggregate behavior of groups of people; they are based on the links that connect us and the ways in which our decisions can have subtle consequences for others. This introductory undergraduate textbook takes an interdisciplinary look at economics, sociology, computing and information science, and applied mathematics to understand networks and behavior. It describes the emerging field of study that is growing at the interface of these areas, addressing fundamental questions about how the social, economic, and technological worlds are connected.

    His only hope for survival is to partner with an alien Artificial Intelligence named Alyssa. She is the brain of the most improbable star ship Gus has ever seen, part ancient sailing ship, part incredible star-faring vessel. But there is a catch. Alyssa’s first priority is to finish an epic yacht race that started twenty-eight thousand years ago. THE WORLD IS CAPTURED BY THE ALIEN DRAMA Every day Gus sends a video love letter to his wife via the lifeboat’s one-way subspace signal where it is automatically posted on YouTube. Few people care until another lifeboat crashes with two young women aboard, both of them celebrities. Their fame turns Gus into a worldwide phenomenon; everyone watches the three castaways fight to carve a life from the tiny island life even though they have little hope of rescue. When disaster threatens, Gus and the girls have no choice but to resurrect the crippled galleon. Their impossible task is to sail Alyssa across an alien sea and then fly her across unimaginable galactic reaches. WHEN ALYSSA FINALLY AGREES TO HELP, SPACE PIRATES STRIKE On live television, the public watches helplessly when a ship of vicious murderers attack the three survivors. The world grieves when the now-famous exiles go silent. At least until Earth's Space Navy reports they are under attack by a ship that is beyond imagination.

    Pilates’ and William J. Miller’s first complete fitness writings. It details the exercises, poses, and instructions fundamental to the matwork developed by Joseph and Clara Pilates. Based on his concepts of a balanced body and mind, and drawn from the approach espoused by the early Greeks, these are the exercises that continue to sustain a worldwide revolution in fitness strategies and exercise techniques. Joseph Pilates has been nothing short of revolutionary in his impact on the world of fitness and exercise. Readers will learn and view the original 34 exercises that Pilates taught to his students, many of whom have become exercise gurus in their own right. These carefully designed exercises constitute the results of decades of scientific study and research into the variety of physical ills that upset the balance of body and mind. Practitioners of Pilates’ forms and exercises in the 21st century continue to expand upon this earlier work by presenting a variety of creative new approaches involving circular movements, standing postures, and core strengthening exercises using props such as tubes, weights, poles, bands, magic circles, mini-balls, stability balls, foam rollers, and more.Now included in this Revised Edition are 18 additional pages of explanations of what has transpired since the original 1945 work, along with several photo/text sequences of the latest 21st-century enhancements in the Pilates world. There are new descriptive pages of text that first describe the fitness principles evolved from Pilates’ original Contrology work. This is followed by detailed text describing 21st-century evolutionary developments that present the key dancers, choreographers, and leaders in the Pilates Studio and certifying organizations through the present. This section ends with a discussion of evolutionary props and apparatus developments, plus 21st-century sample exercises drawn from our larger new book, Pilates Evolution for the 21st Century. Following this section are three complete prop-based demonstration exercises that include both photographic sequences (four per exercise) and step-by-step instructions for 21st-century Pilates exercises using the magic circle, elastic resistance, and the small fitness mini-ball.
