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.Know More
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 about Inventions

The Ancient Egyptians are the well-known constructors of the Pyramids and the Great Sphinx. They invented hieroglyphs, one of the earliest writing systems, and a number system for whole numbers and fractions, including rudimentary algebraic formulations. Egyptians created breath mints, toothpaste, the calendar and bowling. Perhaps their greatest invention, however, was papyrus scrolls, which allowed information to be collected, transported and stored for immediate use or for future generations.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 >
