A website's ranking on Google can spell the difference between success and failure for a new business. NCAA football ratings determine which schools get to play for the big money in postseason bowl games. Product ratings influence everything from the clothes we wear to the movies we select on Netflix. Ratings and rankings are everywhere, but how exactly do they work? Who's #1? offers an engaging and accessible account of how scientific rating and ranking methods are created and applied to a variety of uses. Amy Langville and Carl Meyer provide the first comprehensive overview of the mathematical algorithms and methods used to rate and rank sports teams, political candidates, products, Web pages, and more. In a series of interesting asides, Langville and Meyer provide fascinating insights into the ingenious contributions of many of the field's pioneers. They survey and compare the different methods employed today, showing why their strengths and weaknesses depend on the underlying goal, and explaining why and when a given method should be considered. Langville and Meyer also describe what can and can't be expected from the most widely used systems. The science of rating and ranking touches virtually every facet of our lives, and now you don't need to be an expert to understand how it really works. Who's #1? is the definitive introduction to the subject. It features easy-to-understand examples and interesting trivia and historical facts, and much of the required mathematics is included.

Why doesn't your home page appear on the first page of search results, even when you query your own name? How do other web pages always appear at the top? What creates these powerful rankings? And how? The first book ever about the science of web page rankings, Google's PageRank and Beyond supplies the answers to these and other questions and more. The book serves two very different audiences: the curious science reader and the technical computational reader. The chapters build in mathematical sophistication, so that the first five are accessible to the general academic reader. While other chapters are much more mathematical in nature, each one contains something for both audiences. For example, the authors include entertaining asides such as how search engines make money and how the Great Firewall of China influences research. The book includes an extensive background chapter designed to help readers learn more about the mathematics of search engines, and it contains several MATLAB codes and links to sample web data sets. The philosophy throughout is to encourage readers to experiment with the ideas and algorithms in the text. Any business seriously interested in improving its rankings in the major search engines can benefit from the clear examples, sample code, and list of resources provided. Many illustrative examples and entertaining asides MATLAB code Accessible and informal style Complete and self-contained section for mathematics review

One of the most extraordinary books ever written about chess and chessplayers, this authoritative study goes well beyond a lucid explanation of how todays chessmasters and tournament players are rated. Twenty years' research and practice produce a wealth of thought-provoking and hitherto unpublished material on the nature and development of high-level talent: Just what constitutes an "exceptional performance" at the chessboard? Can you really profit from chess lessons? What is the lifetime pattern of Grandmaster development? Where are the masters born? Does your child have master potential? The step-by-step rating system exposition should enable any reader to become an expert on it. For some it may suggest fresh approaches to performance measurement and handicapping in bowling, bridge, golf and elsewhere. 43 charts, diagrams and maps supplement the text. How and why are chessmasters statistically remarkable? How much will your rating rise if you work with the devotion of a Steinitz? At what age should study begin? What toll does age take, and when does it begin? Development of the performance data, covering hundreds of years and thousands of players, has revealed a fresh and exciting version of chess history. One of the many tables identifies 500 all-time chess greatpersonal data and top lifetime performance ratings. Just what does government assistance do for chess? What is the Soviet secret? What can we learn from the Icelanders? Why did the small city of Plovdiv produce three Grandmasters in only ten years? Who are the untitled dead? Did Euwe take the championship from Alekhine on a fluke? How would Fischer fare against Morphy in a ten-wins match? 1t was inevitable that this fascinating story be written, ' asserts FIDE President Max Euwe, who introduces the book and recognizes the major part played by ratings in today's burgeoning international activity. Although this is the definitive ratings work, with statistics alone sufficient to place it in every reference library, it was written by a gentle scientist for pleasurable reading -for the enjoyment of the truths, the questions, and the opportunities it reveals.

In 1978, Sally Ride, a PhD candidate at Standford University, responded to a newspaper ad to join the US astronaut program. She was accepted and became the first American woman astronaut to fly in space! Among her other accomplishments, she played tennis like a professional, was an astrophysicist who helped develop a robotic arm for space shuttles, and later, through Sally Ride Science, worked to make science cool and accessible for girls. Sally Ride, who died on July 23, 2012, will continue to inspire young children.

“Big questions are Gazzaniga’s stock in trade.” —New York Times “Gazzaniga is one of the most brilliant experimental neuroscientists in the world.” —Tom Wolfe “Gazzaniga stands as a giant among neuroscientists, for both the quality of his research and his ability to communicate it to a general public with infectious enthusiasm.” —Robert Bazell, Chief Science Correspondent, NBC News The author of Human, Michael S. Gazzaniga has been called the “father of cognitive neuroscience.” In his remarkable book, Who’s in Charge?, he makes a powerful and provocative argument that counters the common wisdom that our lives are wholly determined by physical processes we cannot control. His well-reasoned case against the idea that we live in a “determined” world is fascinating and liberating, solidifying his place among the likes of Oliver Sacks, Antonio Damasio, V.S. Ramachandran, and other bestselling science authors exploring the mysteries of the human brain.

The Russia Hoax

Fox News legal analyst Gregg Jarrett reveals the real story behind Hillary Clinton’s deep state collaborators in government and exposes their nefarious actions during and after the 2016 election. The Russia Hoax reveals how persons within the FBI and Barack Obama’s Justice Department worked improperly to help elect Hillary Clinton and defeat Donald Trump in the 2016 presidential election. When this suspected effort failed, those same people appear to have pursued a contrived investigation of President Trump in an attempt to undo the election results and remove him as president. The evidence suggests that partisans within the FBI and the Department of Justice, driven by personal animus and a misplaced sense of political righteousness, surreptitiously acted to subvert electoral democracy in our country. The book will examine: How did Hillary Clinton manage to escape prosecution despite compelling evidence she violated the law? Did Peter Strzok, James Comey, Andrew McCabe, Loretta Lynch, and others obstruct justice by protecting Clinton? Why was there never a legitimate criminal investigation of Clinton in the Uranium One case? Are the text messages exchanged between Strzok and FBI lawyer Lisa Page evidence of a concerted effort to undermine the electoral process? Was there ever any real evidence of "collusion" between Trump and the Russians? Did Trump obstruct justice in the firing of Comey or was he legally exercising his constitutional authority? Did the FBI and DOJ improperly use a discredited "dossier" about Trump to obtain a FISA warrant to spy on Trump associates? Should Muller have disqualified himself under the special counsel law based on glaring conflicts of interest? Was fired National Security Adviser Michael Flynn unfairly charged with making a false statement? With insightful analysis and a fact-filled narrative, The Russia Hoax delves deeply into Democrat wrongdoing.
