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.
John Adams was an American statesman and politician and the second President of the United States (1797-1801).
The Adamses were among the first Puritan settlers in New England, and John's father was a farmer and shoemaker. John Adams graduated from Harvard College, taught grammar school in Worcester, Massachusetts, and then practiced law in Boston. In 1764, Adams married Abigail Smith, a minister's daughter, who became his confidante and lifelong political partner.
In 1765, Adams wrote "A Dissertation on Canon Law and Feudal Law," where he justified his opposition to British interference in the colonies. In the summer of 1774, Adams was elected to the Massachusetts delegation to the First Continental Congress, in which he became a major figure. He wrote Thoughts on Government as a basic guide to drafting new state constitutions. In July 1776, John Adams drafted the Plan of Treaties, which became the basis for the treaty with France and set the strategic priorities that would shape American foreign policy over the next century.
He was elected to the post of head of the War Council, in 1780 he became the author of the Massachusetts Constitution, which became a model for other states, in 1783 he signed the Treaty of Paris. From 1785 to 1788 John Adams served as the first American ambassador to Great Britain and proved himself worthy in this difficult situation, being the official embodiment of American independence from the British Empire. He studied European history extensively and the result was his three-volume book entitled A Defense of the Constitution of the Government of the United States of America (1787).
In 1789 Adams became the country's first vice president (Washington was the first president of the United States), and in 1797 he was elected the second president of the United States. However, his reign was not the best in the history of the new country. Deteriorating relations with France led to an undeclared naval war between the former allies. In 1798, Adams signed the controversial Alien and Sedition Acts, which restricted free speech rights. They met widespread opposition across the country. Adams resisted opposition demands for all-out war with France, but lost the 1800 election to Thomas Jefferson.
John Adams retired from politics and settled in his hometown of Quincy. He became the founder of an entire dynasty of politicians and died on July 4, 1826 (the 50th anniversary of the Declaration of Independence), living to see his eldest son John Quincy elected as the sixth president.
