Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets move around the Sun in elliptical orbits.
Kepler created the three fundamental laws of planetary motion. He also did seminal work in optics and geometry, calculated the most accurate astronomical tables, and made many inventions and discoveries in physics on which further scientific discoveries by advanced scientists were based.

Sir John Frederick William Herschel, 1st Baronet was a British astronomer and son of the Uranus discoverer Wilhelm Herschel. He is credited with the first double star and nebula catalogues of the southern starry sky, which he observed during a five-year stay near Cape Town.

Christiaan Huygens van Zeelhem was a Dutch mechanic, physicist, mathematician, inventor and astronomer who formulated the wave theory of light.
An admirer of Descartes, Huygens preferred to conduct new experiments himself to observe and formulate laws. In physics, he contributed to the development of the crucial Huygens-Fresnel principle, which applies to wave propagation. He also extensively investigated free fall. He experimentally proved the law of conservation of momentum. He derived the law of centrifugal force for uniform circular motion.
He also invented the pendulum clock, discovered centrifugal force and the true shape of Saturn's rings as well as its moon Titan. Huygens is considered the first theoretical physicist to use formulas in physics and one of the founders of theoretical mechanics and probability theory.

Tycho Brahe, born Tyge Ottesen Brahe, more commonly called Tycho, was a prominent Danish astronomer, astrologer, and alchemist of the Renaissance.
As a young man he traveled extensively throughout Europe, studying in Wittenberg, Rostock, Basel, and Augsburg and acquiring mathematical and astronomical instruments. In 1572 Tycho unexpectedly even for himself discovered a new star in Cassiopeia, and the publication of this turned the young Dane into an astronomer of European reputation. For further astronomical research he established an observatory and gathered around him modern progressive scientists.
Besides practicing astronomy, Tycho was an artist, scientist, and craftsman, and everything he undertook or surrounded himself with had to be innovative and beautiful. He even founded a printing house to produce and bind his manuscripts in his own way, and he perfected sanitary ware for convenience. His development of astronomical instruments and his work in measuring and fixing the positions of the stars laid a solid foundation for future discoveries.
Tycho's observations - the most accurate possible before the invention of the telescope - included a comprehensive study of the solar system and the precise positions of more than 777 fixed stars. What Tycho accomplished using only his simple instruments and intellect remains a remarkable achievement of the Renaissance.
Isaac Newton was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus.
In the Principia, Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of the equinoxes and other phenomena, eradicating doubt about the Solar System's heliocentricity. He demonstrated that the motion of objects on Earth and celestial bodies could be accounted for by the same principles. Newton's inference that the Earth is an oblate spheroid was later confirmed by the geodetic measurements of Maupertuis, La Condamine, and others, convincing most European scientists of the superiority of Newtonian mechanics over earlier systems.
