Otto von Guericke invented the air pump in 1650. This invention demonstrated that a vacuum could exist, something previously considered impossible. Asserting the existence of the vacuum was essential to future study and innovation in electronics and other areas of research.
Von Guericke's invention and his elaborate demonstrations disproved the notion that nature abhors a vacuum. Instead, he proved that substances were not pulled by a vacuum, but were pushed by the pressure of the surrounding fluids.
The inventor also applied the barometer to weather prediction, thus paving the way for the study of meteorology and the very first electric generator in 1660.Learn More

Albert Einstein worked in the fields of mathematics and physics, and most of his contributions were in terms of academic theory. There is, however, a refrigerator that bears his name, and he had also developed a compass, a gyrocompass and a hearing aid.Full Answer >
Italian astronomer Galileo Galilei was the inventor of the first pendulum clock, after his discovery of isochronism, which is the time that the pendulum takes to swing. Contrary to popular belief, Galileo was not the inventor of the telescope; Galileo built a telescope based on creations by the Dutch, and it was known as a spyglass. Galileo also built a thermometer and a compass during his lifetime.Full Answer >
