Böcker av Joseph Adler

During my forty-eight years of teaching United States History, there were several myths that students had heard about Abraham Lincoln, African Slaves and the Civil War.When we began studying the unit on these topics and Abraham Lincoln's name was mentioned in discussion, in almost every class I taught students would say, "I heard that Lincoln owned slaves." Then students would tell me they learned in classes they took that slavery had nothing to do with the Civil War. And some students would point out there are superior races of people and inferior races of people, and that the inferior races are only fit for doing menial jobs.I started teaching in 1958, and I am writing this book in 2023 when I am 90 years old. The community where I started teaching was a suburban area of Los Angeles and teachers would tell me that until recently black people "knew" they were not permitted in the streets at night.I decided to write this book to set the record straight, because many of these attitudes still permeate our culture:¿ Lincoln was not a slave owner.¿ Slavery was the cause of the Civil War.¿ There are not superior and inferior races of people.I know you will enjoy reading and learning about the truth of the historical background of these topics.I taught United States History in a special and unique way. In my classes I would bring my guitar each session and sing at least one song that the people used to sing during the time period being discussed in class. To make this book more meaningful, and show how one important aspect of human experience, music can be integrated into an historical analysis. There will be songs that the slaves sang and songs that the soldiers sang. This will add a dimension to understand the historical events that most histories do not. I recorded these songs so you may, if you wish, join with me as I sing the melodies of the songs. The recordings are included as links within this book. I did not put in all the words to these songs because I did not intend the reader to see this as a songbook. It is an historical analysis, which includes songs.I hope you will enjoy this approach as my students did.

Baseball Hacks isn't your typical baseball book--it's a book about how to watch, research, and understand baseball. It's an instruction manual for the free baseball databases. It's a cookbook for baseball research. Every part of this book is designed to teach baseball fans how to do something. In short, it's a how-to book--one that will increase your enjoyment and knowledge of the game.So much of the way baseball is played today hinges upon interpreting statistical data. Players are acquired based on their performance in statistical categories that ownership deems most important. Managers make in-game decisions based not on instincts, but on probability - how a particular batter might fare against left-handedpitching, for instance. The goal of this unique book is to show fans all the baseball-related stuff that they can do for free (or close to free). Just as open source projects have made great software freely available, collaborative projects such as Retrosheet and Baseball DataBank have made great data freely available. You can use these data sources to research your favorite players, win your fantasy league, or appreciate the game of baseball even more than you do now.Baseball Hacks shows how easy it is to get data, process it, and use it to truly understand baseball. The book lists a number of sources for current and historical baseball data, and explains how to load it into a database for analysis. It then introduces several powerful statistical tools for understanding data and forecasting results.For the uninitiated baseball fan, author Joseph Adler walks readers through the core statistical categories for hitters (batting average, on-base percentage, etc.), pitchers (earned run average, strikeout-to-walk ratio, etc.), and fielders (putouts, errors, etc.). He then extrapolates upon these numbers to examine more advanced data groups like career averages, team stats, season-by-season comparisons, and more. Whether you're a mathematician, scientist, or season-ticket holder to your favorite team, Baseball Hacks is sure to have something for you.Advance praise for Baseball Hacks:"e;Baseball Hacks is the best book ever written for understanding and practicing baseball analytics. A must-read for baseball professionals and enthusiasts alike."e;-- Ari Kaplan, database consultant to the Montreal Expos, San Diego Padres, and Baltimore Orioles"e;The game was born in the 19th century, but the passion for its analysis continues to grow into the 21st. In Baseball Hacks, Joe Adler not only demonstrates thatthe latest data-mining technologies have useful application to the study of baseball statistics, he also teaches the reader how to do the analysis himself, arming the dedicated baseball fan with tools to take his understanding of the game to a higher level."e;-- Mark E.
