He could figure out the volume of irregularly-shaped objects this way, or of elements with mixed proportions of copper, zinc, silver, or gold. The amount which the counterweight had moved when it was immersed in water could be measured by the number of turns of the wire. He created a balance for weighing things in the air, and the counterweight was wrapped with metal wire used to balance it in water. It was frequently used by jewelers to display the purity of their metals. Christiaan Huygens built the first working version of this model, based on Galileo’s design, in 1657.īased on Archimedes’ principle of hydrostatic weighing of different objects, he invented a device called the ‘bilancetta’, or little balance. This also helped doctors measure the heartbeat of patients, which helped diagnose their condition. Together, they kept track of the accurate time, which was instrumental in creating the first timepiece which measured time. He experimented with two pendulums at his house, swinging one in a larger arc and the other in a smaller arc. While studying medicine, Galileo found the swinging of a chandelier took the same amount to return to its initial position, irrespective of the arcs. List of Galileo’s Inventions Discovery of the Pendulum Galileo’s Two Sciences is published in Holland and is now called the kinematics and strength of materials. Galileo’s Dialogue Concerning the Two Chief World Systems is published. Observed sunspots moving, which led him to the conclusion that the sun rotates on its own axis. He measured the heights of the mountains based on their shadows.ĭiscovered the Milky Way was made up of stars too far away to be seen by the naked eye.ĭiscovered the four satellites orbiting Jupiter.ĭiscovered Ganymede, the largest Moon of Jupiter which supported the Copernican model. He invented the telescope and magnified the power of the lens by 30.ĭiscovers the Moon has craters on it. Invents the thermoscope, the primitive thermometer. Invents the ‘sector’, the military compass used for solving mathematical problems of proportion, trigonometry, multiplication, and division.Įxperiments with the uniform theory of acceleration and publishes his Laws of Motion. Observed the isochronism of a chandelier and invented the pendulum.įollows Archimedes’ principle of hydrostatic weighing and created the ‘bilancetta’. In the memory of this great man, let’s take a look at the list of the discoveries made by Galileo Galilei. Although he was one of the most revered inventors of all time, he spent his last years under house arrest. ![]() But his plea had fallen on deaf ears, and he was prosecuted for heresy against the Church. ![]() His inventions even gained him the ear of Pope Urban VIII, and he was favored by the Catholic Church, as he was the first to propose the unity of faith and reason towards the betterment of science and progress. With a firm insight and focus, he detailed all his observations for future use. If you thought physics was his only forte, he proved us wrong by observing the heavenly bodies above. While everybody accepted all celestial bodies revolved around the Earth, he was the first to prove them wrong with scientific experiments and data to back up his theory. But the person who made this possible by contributing to the principles of physics was Galileo Galilei.Īlthough Galileo was a professor of mathematics, by profession, he constantly tinkered around with gadgets, unable to contain his fascination for science. ![]() Today, with the advances in science, we can reach the Moon easily, and expend our efforts trying to explore space and solve its infinite mysteries. While many thought reaching the Moon would be a pipe-dream, two astronauts proved us wrong by taking their first steps on the Moon. ![]() The Moon shines infinitely enveloping us with its luminosity. The charges of heresy against Galileo were dropped after 300 years.
