Today’s personal computers are drastically different from the massive, hulking machines that emerged out of World War II–and the difference isn’t only in their size. By the 1970s, technology had evolved to the point that individuals–mostly hobbyists and electronics buffs–could purchase unassembled PCs or “microcomputers” and program them for fun, but these early PCs could not perform many of the useful tasks that today’s computers can. Users could do mathematical calculations and play simple games, but most of the machines’ appeal lay in their novelty. Today, hundreds of companies sell personal computers, accessories and sophisticated software and games, and PCs are used for a wide range of functions from basic word processing to editing photos to managing budgets. At home and at work, we use our

Iron, Coal, and Steam

Early in the 1700s two English inventors set the stage for the Industrial Revolution. This was a period of great growth of industry. Abraham Darby discovered that a coke-burning furnace produced good iron. Coke is a form of coal. Thomas Newcomen invented a pump that kept coal mines from filling with water. A steam engine powered the pump.

With these developments, coal and iron production expanded rapidly. Iron remained the main metal for building and toolmaking until the late 1800s. At that time steel (a mixture of iron and carbon) began to replace regular iron.

Meanwhile, in the late 1700s steam began to replace wind and water as the major source of power. In a steam engine, burning coal heated water. The boiling water produced the steam that ran the engine.

Other inventions also sped up the production of goods—especially textiles, or cloth.

  5. The World Wide Web

Unlike technologies such as the light bulb or the telephone, the internet has no single “inventor.” Instead, it has evolved over time. The internet got its start in the United States more than 50 years ago as a government weapon in the Cold War. For years, scientists and researchers used it to communicate and share data with one another. Today, we use the internet for almost everything, and for many people it would be impossible to imagine life without it.

The Sputnik Scare

On October 4, 1957, the Soviet Union launched the world’s first manmade satellite into orbit. The satellite, known as Sputnik, did not do much: It relayed blips and bleeps from its radio transmitters as it circled the Earth. Still, to many Americans, the beach-ball-sized Sputnik was proof of something alarming:
