Zipper Joins Fast
Zipper Joins Fast explores the fascinating history and technological innovation behind the zipper, a seemingly simple device that revolutionized the garment industry and consumer culture. The book examines how this invention, patented in 1917, transformed clothing design and manufacturing, replacing cumbersome buttons and laces with speed and efficiency. One intriguing aspect is Gideon Sundback's pivotal role in perfecting the design through numerous iterations. Another is how the zipper's widespread adoption spurred mass production and changed labor practices, impacting the economics of the fashion world. The book begins by detailing pre-zipper closure methods and the early clasp-lockers, then progresses through the key figures and design evolutions led by Sundback. It dedicates a chapter to the mechanics of zipper construction and analyzes its influence on clothing manufacturing. Ultimately, it examines the zipper's presence in contemporary fashion, its symbolic meanings, and its role in discussions about sustainability. The book uses diverse sources, including patent documents, trade catalogs, and advertising campaigns, to support its arguments. This approach emphasizes the zipper not just as a functional object but as a cultural artifact embodying innovation and technological change.

Dive Into Algorithms is a broad introduction to algorithms using the Python Programming Language. Dive Into Algorithms is a wide-ranging, Pythonic tour of many of the world's most interesting algorithms. With little more than a bit of computer programming experience and basic high-school math, you'll explore standard computer science algorithms for searching, sorting, and optimization; human-based algorithms that help us determine how to catch a baseball or eat the right amount at a buffet; and advanced algorithms like ones used in machine learning and artificial intelligence. You'll even explore how ancient Egyptians and Russian peasants used algorithms to multiply numbers, how the ancient Greeks used them to find greatest common divisors, and how Japanese scholars in the age of samurai designed algorithms capable of generating magic squares. You'll explore algorithms that are useful in pure mathematics and learn how mathematical ideas can improve algorithms. You'll learn about an algorithm for generating continued fractions, one for quick calculations of square roots, and another for generating seemingly random sets of numbers. You'll also learn how to: • Use algorithms to debug code, maximize revenue, schedule tasks, and create decision trees • Measure the efficiency and speed of algorithms • Generate Voronoi diagrams for use in various geometric applications • Use algorithms to build a simple chatbot, win at board games, or solve sudoku puzzles • Write code for gradient ascent and descent algorithms that can find the maxima and minima of functions • Use simulated annealing to perform global optimization • Build a decision tree to predict happiness based on a person's characteristics Once you've finished this book you'll understand how to code and implement important algorithms as well as how to measure and optimize their performance, all while learning the nitty-gritty details of today's most powerful algorithms.
