Gian Battista Valentini, known as Nanni Valentini, was an Italian painter, sculptor and ceramist.
Jan Swammerdam was a Dutch naturalist and biologist, anatomist and microscopist.
Swammerdam graduated from the Faculty of Medicine at Leiden University, then studied in Paris, earning a doctorate in medicine, and devoted himself exclusively to microscopic research. He used a single-lens microscope to study insect anatomy, and accurately described and illustrated the life history and anatomy of many species. His observations of their development allowed him to divide insects into four major divisions according to the degree and type of metamorphosis. His greatest contribution to biology was to understand insect development and to demonstrate that the same organism persists through different stages.
Jan Swammerdam wrote a voluminous work entitled A General History of Insects (1669) and The Bible of Nature (1737-1738), one of the finest collections of microscopic observations ever published. Considered the most accurate of the classical microscopists, he was the first to observe and describe erythrocytes in 1658.
Swammerdam was also a recognized anatomist: in 1670 he was granted the privilege of dissecting human bodies in Amsterdam, which at the time required a special license available only to a limited number of researchers. He developed a new dissection technique and also designed several new instruments.
John Milton was a British poet and writer-publicist, intellectual and politician of the English Revolutionary period.
Milton first planned to become a priest, studied at Cambridge University, and then abandoned this activity. Several years he spent reading and self-education, learning many languages. In 1638 Milton traveled around the continent for about a year and a half, spending much time in Italy, primarily in Rome and Florence. He befriended young Italian literati, and his encounter with Galileo further influenced his writing.
Milton became best known for his poem Paradise Lost in Ten Books, which declares its purpose to justify the ways of God to man, but also touches on both universal and personal themes. Milton was the first author to use the word "cosmos" in our modern sense of "outer space," and his space epic takes place in a confidently Copernican universe.
In his prose works, Milton advocated the abolition of the Church of England and the execution of Charles I. From the outbreak of the English Civil Wars in 1642 and long after the restoration of Charles II as king in 1660, he spoke out against tyranny and state-sanctioned religion in all his works. As a Protestant, Milton was often in conflict with the Roman Catholic Church. As a civil servant, Milton became the voice of the English Commonwealth after 1649 and then under Oliver Cromwell, conducting international correspondence and defending the government against polemical attacks from abroad.
John Milton is considered the most important English writer after William Shakespeare. Author of political pamphlets and religious treatises, he is one of the most famous writers of the 1650s, the vibrant era of the English Revolution (Civil War).
Albert Einstein was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics. His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius".
