The Modern Submarine
The original submarine was made in the 1880s, but the version used today didn't become popular until the 20th century. It was used as an underwater weapon for World War One, and is now primarily used in the navy. This has developed a lot over time, due to things like nuclear energy. -
The Automobile
This very commonly used device used for transportation, used to not be used at all. Most people thought it was impractical, until the 20th century, when it became what it is today. A primary source of transportation for most people. -
The Airplane
This was one idea made real by two brothers who decided they wanted to fly. They created a long distance transportation device that is commonly used today. People use airplanes for travel and to transport things across the world. -
Antibiotics
This type of medicine is good and bad in many ways. Some people can be allergic to certain antibiotics, or certain ones can give someone a different type of infection. They do fight against many illnesses, and they do a good job, most of the time -
The Personal Computer
Most people can't imagine their life without their computer. These first editions of them are huge and clunky and not portable. Even with this fact, it was still a revolution to everyone who had one at the time. -
My Reasoning
The reason I chose the order that they are in is because all of these things are very important, but some are more commonly used than others. The submarine was important, but is it as important as antibiotics that help save someones life? That is how I chose the importance of these discoveries.
