Did you know . . . • Ancient cultures measured time accurately with water clocks? • An engineer in the first century B.C. designed an odometer to calculate distance traveled? • People computed the first values of pi about four thousand years ago? Computing technology is as old as human society itself. The first humans on Earth used basic computing skills. They counted by carving tally marks in bone. They used body parts and basic tools to measure. Over the centuries, ancient peoples learned more about computing. People in the ancient Middle East used scales to measure goods for trading. The ancient Egyptians wrote textbooks including multiplication and division problems. The ancient Chinese developed an abacus for speedy calculations. Ancient Greeks made advances in geometry. What kinds of tools and techniques did ancient mathematicians use? Which of their inventions and discoveries have stood the test of time? And how did the ancients set the stage for our own modern computing? Learn more in Ancient Computing Technology.

Computer: A History of the Information Machine traces the history of the computer and shows how business and government were the first to explore its unlimited, information-processing potential. Old-fashioned entrepreneurship combined with scientific know-how inspired now famous computer engineers to create the technology that became IBM. Wartime needs drove the giant ENIAC, the first fully electronic computer. Later, the PC enabled modes of computing that liberated people from room-sized, mainframe computers. This third edition provides updated analysis on software and computer networking, including new material on the programming profession, social networking, and mobile computing. It expands its focus on the IT industry with fresh discussion on the rise of Google and Facebook as well as how powerful applications are changing the way we work, consume, learn, and socialize. Computer is an insightful look at the pace of technological advancement and the seamless way computers are integrated into the modern world. Through comprehensive history and accessible writing, Computer is perfect for courses on computer history, technology history, and information and society, as well as a range of courses in the fields of computer science, communications, sociology, and management.

Describes the mathematical technology used by ancient societies, covering techniques used for counting, measurements, weights, time, and calculations, including the ancient civilizations of China, Greece, Rome, India, and the Middle East.

In Antikythera Mechanism: The Story Behind the Genius of the Greek Computer and Its Demise, Evaggelos Vallianatos, historian and ecopolitical theorist, shows that after the conquest of Persia by Alexander the Great in the late fourth century BCE, the Greeks, especially in Egypt, reached unprecedented heights of achievements in science, technology, and civilization. The Antikythera Mechanism, an astronomical computer probably crafted in Rhodes in the second century BCE, was proof of that prowess. It’s the grandfather of our computers. Greek sponge divers discovered the Antikythera Mechanism in 1900 on a 2,100-year-old Roman-era shipwreck. The hand-powered device reveals a sophisticated Greek technology previously unknown to scholars and historians, not seen and understood again until the twentieth and twenty-first centuries. The book not only describes how the sophisticated political and technological infrastructure of the Greeks after Alexander the Great resulted in the Antikythera celestial computer, and the bedrock of science and technology we know today, but also how the influence of Christianity on Greek civilization destroyed the nascent computer age of ancient Greece. Vallianatos, born in Greece and educated in America, is a historian, author, and journalist. He is a passionate champion of Greek culture and a well-suited guide to this historical account. Vallianatos explains how and why Greek scientists employed advanced engineering in translating the beautiful conception of the Antikythera Mechanism into an astronomical computer of genius: a bronze-geared device of mathematical astronomy, predicting the eclipses of the Sun and the Moon; calculating the risings and settings of important stars and constellations, and the movements of the planets around the Sun; while mechanizing the predictions of scientific theories. The computer’s accurate calendar connected these cosmic phenomena to the Olympics and other major Panhellenic religious and athletic celebrations, bringing the Greeks closer to their gods, traditions, and the Cosmos.

A strikingly illustrated overview of the computing machines that have changed our world—from the abacus to the smartphone—and the people who made them, by the New York Times bestselling author and illustrator of Women in Science. “A beautifully illustrated journey through the history of computing, from the Antikythera mechanism to the iPhone and beyond—I loved it.”—Eben Upton, Founder and CEO of Raspberry Pi ONE OF THE BEST BOOKS OF THE YEAR: The New York Public Library Computers are everywhere and have impacted our lives in so many ways. But who created them, and why? How have they transformed the way that we interact with our surroundings and each other? Packed with accessible information, fun facts, and discussion starters, this charming and art-filled book takes you from the ancient world to the modern day, focusing on important inventions, from the earliest known counting systems to the sophisticated algorithms behind AI. The History of the Computer also profiles a diverse range of key players and creators—from An Wang and Margaret Hamilton to Steve Jobs and Sir Tim Berners-Lee—and illuminates their goals, their intentions, and the impact of their inventions on our everyday lives. This entertaining and educational journey will help you understand our most important machines and how we can use them to enhance the way we live. You’ll never look at your phone the same way again!

Silicon Valley gets all the credit for digital creativity, but this account of the pre-PC world, when computing meant more than using mature consumer technology, challenges that triumphalism. The invention of the personal computer liberated users from corporate mainframes and brought computing into homes. But throughout the 1960s and 1970s a diverse group of teachers and students working together on academic computing systems conducted many of the activities we now recognize as personal and social computing. Their networks were centered in New Hampshire, Minnesota, and Illinois, but they connected far-flung users. Joy Rankin draws on detailed records to explore how users exchanged messages, programmed music and poems, fostered communities, and developed computer games like The Oregon Trail. These unsung pioneers helped shape our digital world, just as much as the inventors, garage hobbyists, and eccentric billionaires of Palo Alto. By imagining computing as an interactive commons, the early denizens of the digital realm seeded today’s debate about whether the internet should be a public utility and laid the groundwork for the concept of net neutrality. Rankin offers a radical precedent for a more democratic digital culture, and new models for the next generation of activists, educators, coders, and makers.

This revised edition of the popular reference and textbook outlines the historical developments in computing technology. It explains and describes historical aspects of calculation with an emphasis on the physical devices used in different times to aid people in their attempts at automating the process of arithmetic.
