GPS was first thought of back in the 1960s, inspired by the Sputnik Satellites. While originally contrived as a military device during the cold wars, now it is used for many other purposes, mostly for consumers, but is also used to map out areas, earthquake research, and climate research.

Telescopes were initially contrived for looking over long distances, the skyward facing one was invented by a man named Galileo. Galileo used telescopes to observe our solar system, moon, and even a distant look at the Milky Way. Over time, Galileo's model was improved in various ways, and telescopes are still used today for that very purpose.

Radio, while initially created by Nikolai Tesla, is often credited to being created by Guglielmo Marconi, who was the first man to transmit radio signals across the sea. While originally used for spy purposes, Radios soon became a common place household item used to distribute music on a large scale.

Smelting is an age old technique in where metals such as copper or iron is melted down into workable forms. Being used for several millenniums now, Smelting is usually done by heating the metal to incredibly hot levels, and then casting it into molds to form the wanted object.

Antiseptics are a common medicine used to prevent infections on wounds, whether it's during surgery or just a plain old scratch. They were originally used by Doctor Joseph Lister, who used carbolic acid (Phenol) to clean his surgical tools. Antiseptics are also used today in common mouthwashes, such as Listerine.
