During the next 100 years, enormous developments changed how people communicated, traveled, and went about their daily lives. These changes are far too numerous to list entirely, but here are a few major inventions and listed them below. It's unlikely you'll need to know all of these for the exam, but an understanding of the impact of the Industrial Revolution is perhaps best grasped by looking at the details. There isn't one item on the list below that you can deny has changed the world.
The Telegraph-Invented in 1837 by Samuel Morse. Allowed people to communicate across great distances within seconds.
The Telephone-Invented in 1876 by Alexander Graham Bell. Don't answer it while you're studying.
The Light bulb-Invented in 1879 by Thomas Edison. Kind of huge.
The Internal Combustion Engine-Invented in 1885 by Gottlieb Daimler. If you've ever been in a car, you've personally benefited from the internal combustion engine.
The Radio-Invented in the 1890s by Marconi Guglielmo.
The Airplane-Invented in 1903 by Orville and Wilbur Wright. It travels ever so slightly faster than a steamship (invented just one hundred years prior).
At the same time, there were huge advances in medicine and science. Pasteurization and vaccinations were developed. X-rays came onto the scene. Charles Darwin developed the concept of natural selection. The developments of this time period go on and on and on.
