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.Know More
Many of Galileo's astronomical discoveries occurred because of the telescope that he had built. With the magnification on his homemade telescope, Galileo was able to study the moon as well as other celestial bodies. Galileo's invention started as a telescope with 3x magnification, but he built upon that idea to create a telescope with 30x magnification. Other inventions of Galileo's included a compass, thermometer and several telescopes.
With Galileo's invented telescopes, he was able to see objects, such as Jupiter's satellite moons. These moons are now known as the Galilean satellites, named after Galileo. While Galileo was an inventor, he was more known for his pursuits in other subjects, such as physics, mathematics, astronomy and philosophy. However, because of Galileo's telescope inventions, he put forth the heliocentric, sun-centered view of the universe. Galileo's synopsis was correct, but he was charged with heresy for it.Learn more in Inventions
Polish astronomer Nicolas Copernicus, considered the father of modern astronomy, is also, for all intents and purposes, the inventor of the globe. To illustrate his belief that the Earth was spherical, Copernicus built globes and terrain models called armillary spheres. These constructions were the first globes.Full Answer >
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 >
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 >
The Wright brothers became interested in airplanes and flying after learning about the studies of the late 19-century glider pilot Otto Lilienthal. They then began to study glider experiments and the theories of flying. Eventually, they became known as the first people to successfully fly a manned, powered flight in a heavier-than-air machine.Full Answer >
