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.

Girolamo Franzosi was an Italian physician and philosopher.
He was born in Polpenazza (now Polpenazze del Garda), near the Lombard lakeshore, in the late sixteenth and early seventeenth centuries. Franzosi was a student at Padua and became a convinced Aristotelian. He opposed the anatomists of the Neoteric Academy, which represented the new trends of medicine in Verona in contrast to the Galenic tendencies of traditional medicine.
Franzosi's other works, written under the influence of Girolamo Cardano and Agostino Nifo, deal with such wide-ranging topics as dreams, prophecies, imagination, and the medicinal properties of viper venom. He printed most of his works in Verona, calling himself "medicus and philosopher of Verona".
Nicolaus Copernicus (Polish: Mikołaj Kopernik) was a Polish and German scientist, astronomer, mathematician, mechanic, economist, and Renaissance canonist. He was the author of the heliocentric system of the world, which initiated the first scientific revolution.
Copernicus studied the humanities, including astronomy and astrology, at the University of Krakow and at the University of Bologna in Italy. Together with other astronomers, including Domenico Maria de Novara (1454-1504), he was engaged in observing the stars and planets, recording their movements and eclipses. At the time, medicine was closely related to astrology, as the stars were believed to influence the human body, and Copernicus also studied medicine at the University of Padua between 1501 and 1503.
Nicolaus Copernicus, based on his knowledge and observations, was the first to suggest that the Earth is a planet that not only revolves around the sun every year, but also rotates once a day on its axis. This was in the early 16th century when people believed the Earth to be the center of the universe. The scientist also suggested that the Earth's rotation explained the rising and setting of the Sun, the movement of the stars, and that the cycle of the seasons was caused by the Earth's rotation around itself. Finally, he correctly concluded that the Earth's motion in space causes the planets to move backwards across the night sky, the so-called retrograde direction.
Although Copernicus' model was not completely correct, it laid a solid foundation for future scientists, such as Galileo, who developed and improved mankind's understanding of the motion of celestial bodies. Copernicus completed the first manuscript of his book De Revolutionibus Orbium Coelestium (On the Rotation of the Celestial Spheres) in 1532. In it, the astronomer outlined his model of the solar system and the paths of the planets. However, he published the book only in 1543, just two months before his death, and dedicated it to Pope Paul III. Perhaps for this reason, and also because the subject matter was too difficult to understand, but the church did not finally ban the book until 1616.
Galileo Galilei was an Italian naturalist, physicist, mechanic, astronomer, philosopher, and mathematician.
Using his own improved telescopes, Galileo Galilei observed the movements of the Moon, Earth's satellites, and the stars, making several breakthrough discoveries in astronomy. He was the first to see craters on the Moon, discovered sunspots and the rings of Saturn, and traced the phases of Venus. Galileo was a consistent and convinced supporter of the teachings of Copernicus and the heliocentric system of the world, for which he was subjected to the trial of the Inquisition.
Galileo is considered the founder of experimental and theoretical physics. He is also one of the founders of the principle of relativity in classical mechanics. Overall, the scientist had such a significant impact on the science of his time that he cannot be overemphasized.

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.

Leonhard Euler was the greatest mathematician of the 18th century and history in general.
Euler brilliantly graduated from the University of Basel and entered the St. Petersburg Academy of Sciences, then began to work at the Berlin Academy, and later to lead it. In 1766, the scientist received an invitation from the Russian Empress Catherine II and again came to St. Petersburg to continue his scientific work.
Here he published about 470 works in a wide variety of fields. One of them is a large-scale work "Mechanics" - an in-depth study of this science, including celestial mechanics. Euler by that time was practically blind, but continued to be actively engaged in science, in the records he was helped by his son Johann Albrecht and stenographers. Leonhard Euler made many fundamental discoveries that brought great benefit to mankind.
His massive contribution to the development of mathematics, mechanics, physics and astronomy cannot be overestimated, and his knowledge in the most diverse branches of science is admirable. During his lifetime, he published more than 850 works that contain in-depth studies of botany, chemistry, medicine, ancient languages, and music. Euler held membership in many academies of science around the world.

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.
