There have been many great inventions in human history. One great invention is the printing press. A German, Johannes Gutenberg, in the 1400s, invented a press that made it easy to print books. Books became much more common after the invention of the printing press. Books helped other inventors make new things.
The invention of the steam engine around 1700 led to the Industrial Revolution. Inventors made many new machines that were powered by steam engines. They invented locomotives, steamboats, and all kinds of factory machines.
The discovery of electricity led to many wonderful inventions. Many scientists studied electricity. An American inventor named Thomas A. Edison invented the electric lamp, phonograph, and other things that ran on electricity in the late 1800s.
New things are invented today faster than ever before. The ways people invent things have changed over time. Until the 1900s, most inventors worked alone. Today, most inventions come from scientists and engineers who work in teams.
