contemporary history
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.

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formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint until it was superseded by the theory of relativity.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.

Abraham Ortelius (Ortels) was a Brabantian cartographer, geographer, and cosmographer. He is recognized as the creator of the first modern atlas, the Theatrum Orbis Terrarum (Theatre of the World). Along with Gemma Frisius and Gerardus Mercator, Ortelius is generally considered one of the founders of the Netherlandish school of cartography and geography. He was a notable figure of this school in its golden age (approximately 1570s–1670s) and an important geographer of Spain during the age of discovery. The publication of his atlas in 1570 is often considered as the official beginning of the Golden Age of Netherlandish cartography. He was the first person proposing that the continents were joined before drifting to their present positions. Beginning as a map-engraver, in 1547 he entered the Antwerp Guild of Saint Luke as an illuminator of maps. In 1560 when travelling with Mercator to Trier, Lorraine, and Poitiers, he seems to have been attracted, largely by Mercator's influence, towards the career of a scientific geographer. In 1564 he published his first map, Typus Orbis Terrarum, an eight-leaved wall map of the world. On 20 May 1570, Gilles Coppens de Diest at Antwerp issued Ortelius's Theatrum Orbis Terrarum, the "first modern atlas" (of 53 maps).
Adam Smith was a Scottish economist and philosopher, one of the founders of economic theory as a science.
After graduating from Balliol College at Oxford University, Smith in 1751 became Professor of Logic and then Professor of Moral Philosophy at the University of Glasgow. And at the same time worked on publishing some of his lectures. His book The Theory of Moral Sentiments was published in 1759. As a philosopher, he wrote on a wide range of subjects: moral philosophy, jurisprudence, rhetoric and literature, and the history of science. He was one of the leading figures of the Scottish Enlightenment. Adam Smith also studied the social forces that give rise to competition, trade, and markets. On his trip to France, he met François Kenet and the Physiocrats.
In late 1763, Smith was given the position of tutor to the young Duke of Buccleugh and resigned his professorship. He began to socialize extensively with the intellectuals of his day, aristocrats and scholars, members of the government and representatives of big commerce, and gradually moved from philosophy to economics.
Adam Smith published his most important work, An Inquiry into the Nature and Causes of the Wealth of Nations (abbreviated as The Wealth of Nations), in 1776. It was the first major exposition of the theory of free trade, where the author advocates individual liberty and the accumulation of wealth, while strongly advocating moral justice and duty to society. He describes a system of natural liberty and justice that seeks to raise the standard of living of the general population by equating higher wages with a healthier and more productive labor force. He proves his belief that the limits to growth are political, not economic, and outlines the principles that should guide lawmakers. Smith also lays out a history of economic theory, a historical analysis of the wealth of nations, including China, and predictions for the future.
"The Wealth of Nations" was the first and still remains the most important book on political economy. And Adam Smith himself is considered the founder of classical political economy; he introduced the term "the invisible hand of the market." Although he did not use the word "capitalism", he is called the father of modern capitalism.
