Sir Isaac Newton is one of the most influential scientists of all time. He came up with numerous theories and contributed ideas to many different fields including physics, mathematics and philosophy.
In 1687, Newton published Philosophae Naturalis Principia Mathematica, what is widely regarded to be one of the important books in the history of science. In it he describes universal gravitation and the three laws of motion, concepts that remained at the forefront of science for centuries after. Newton’s law of universal gravitation describes the gravitational attraction between bodies with mass, the earth and moon for example.
Johannes Kepler helped lead a scientific revolution in the 17th century with his amazing work in the field of astronomy. Among his many contributions were the three laws of planetary motion.
Kepler achieved much of his work around the same time as another famous astronomer, Galileo Galilei. The two often had disagreeing opinions but their concurrent work helped spur physics, philosophy and astronomy forward rapidly to a new level of understanding.
Galileo Galilei is an Italian scientist best known for his works that contributed to a new way of thinking about how our solar system works and astronomy in general.
Born in Pisa, Italy on February 15, 1564, Galileo was an inventor and a pioneer in the field of astronomy, physics, mathematics, and philosophy.
Among his many inventions were telescopes, a compass, and a thermometer. With his telescopes, Galileo was able to observe the skies like never before. In 1610, he made observations of four objects that surround the planet Jupiter. Behaving unlike stars, these objects turned out to be Jupiter’s largest satellite moons: Europe, Callisto, Io, and Ganymede. They were later renamed “Galilean satellites” to honor Galileo.
The geocentric model of the universe, which was also supported by earlier astronomers, has the planet Earth at the very center of the universe, with other heavenly bodies moving around it. But Galileo’s work, along with other scientists like Johannes Kepler and Nicolaus Copernicus, superseded this theory with a more accurate heliocentric model, placing the Sun as the center of the universe and the planets orbiting around it.
