Nicolas Chuquet was a 15th century French mathematician.
The exact dates of birth and death of this scientist are not known, nor are the places of birth. Chuquet received a Bachelor of Medicine degree from the University of Paris, went to Italy in the early 1470s, and around 1480 moved to Lyon, where he worked as a physician, mathematics teacher, and scribe. He is also known to have translated Latin works into French.
In 1484 he wrote his major algebraic work, the treatise Le Triparty en la Science des Nombres (The Science of Numbers in Three Parts), now considered one of the most original mathematical texts of the 15th century. At the time, arithmeticians lacked even the most basic notations for addition subtraction, multiplication, and division. Chuquet was one of the first to propose these symbols; he also introduced the names of large numbers into common use: billion, trillion, etc. In addition to general arithmetic and rules for calculating roots, the treatise contains a doctrine of equations and a collection of problems.
This treatise was published only in 1880, but the works of Nicolas Chuquet had a significant influence on the development of algebra, and they were consistently supplemented and expanded by scientists of the following generations.


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".

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.


Johann Zahn (German: Johann or Johannes Zahn) was a German scientist and philosopher, optician and astronomer, mathematician and inventor.
Zahn studied mathematics and physics at the University of Würzburg, was professor of mathematics at the University of Würzburg, and served as a canon of the Order of Regular Canon Premonstratensians. His other activities were optics as well as astronomical observations.
In 1686 Johann Zahn invented and designed a portable camera obscura with fixed lenses and an adjustable mirror, which is the prototype of the camera. In his treatise on optics, Oculus Artificialis Teledioptricus (1702), Zahn gives a complete picture of the state of optical science of his time. He begins with basic information about the eye and then moves on to optical instruments. The book is aimed at eighteenth-century microscope and telescope enthusiasts and includes all the necessary details of construction, from lens grinding to drawings.


Gaius Pliny Secundus (Latin: Gaius Plinius Secundus), known as Pliny the Elder, was an ancient Roman polymath, writer and statesman.
Pliny came from a wealthy family and was educated in Rome. In military service in Germany, he rose to the rank of cavalry commander, and then returned to Rome and was appointed governor of the province. In addition to public affairs, Pliny was engaged in the study of nature, wrote various scientific works.
His book Natural History has reached our time. This is an encyclopedic work, which became an authority in Europe in scientific matters until the Middle Ages. Natural History has historical significance as one of the greatest literary monuments of classical antiquity. It is still of value to those who wish to gain an insight into first-century Rome from a primary source.
In the year 79 Pliny was appointed by Vispasian to command a fleet in the Bay of Naples, and found himself near Vesuvius at the time of its eruption. He went ashore, where he died as a result of the natural disaster.


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.


Edward Donovan was a British-Irish amateur zoologist, illustrator and writer.
He was an avid collector and founded the Natural History Museum and Institute in London, which housed his extensive collection of natural history objects. Donovan was the author of a large number of works on natural history, and wrote several volumes on British birds, fish, and insects, botanical surveys, and on the entomology of China and India. All of these publications were supplied with good quality and detailed illustrations.


Charles Robert Darwin was an English naturalist, geologist, and biologist, widely known for contributing to the understanding of evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.


Fortunio Liceti (Latin: Fortunius Licetus) was an Italian physician, natural philosopher, writer and educator.
Liceti studied philosophy and medicine at the University of Bologna and earned doctorates in these disciplines. He taught logic and philosophy at the University of Pisa, and became professor of philosophy at the University of Padua and the University of Bologna. At the University of Padua, Liceti became friends with Galileo Galilei.
Liceti's inquisitive mind was interested in a wide range of subjects: from genetics and reproduction to gems and animals. In general, Fortunio Liceti was a very industrious and prolific scientist: he published a book each year, writing more than seventy works on a wide range of subjects, including the human soul, reproduction, and birth defects.
In 1616, Liceti wrote and published the first edition of De monstruorum causis, natura et differentiis (On the Causes, Nature, and Differences of Monsters), a chronologically ordered catalog of monsters from antiquity to the seventeenth century. Among these monsters were infants with congenital malformations. Liceti was one of the first scholars to attempt to systematically categorize birth defects according to their causes, including numerous causes not related to the supernatural. This topic interested the scientist greatly and he returned to it several times during his life, supplementing it with illustrations, among other things. From 1640 to 1650. Liceti also wrote and published seven different volumes in which he answered questions from famous people on a wide variety of medical topics.


Carl Linnaeus was a Swedish naturalist, botanist and physician.
Carl Linnaeus created a unified system of classification of flora and fauna, in which he summarized and organized the knowledge of the entire previous period of development of biological science. He was the first to formulate the principles of definition of living beings of natural nature and created a unified system of their names, binary nomenclature. Linnaeus' book "The System of Nature", first published in 1735, is one of the most important books in the history of science and practically opened the classification of plants and animals.
Linnaeus was a professor at Uppsala University for many years, and he is also valued in Sweden as one of the creators of the literary Swedish language in its modern form. In addition to his work in botany and scientific classification, Linnaeus led many activities for the betterment of his native country. He was also involved in the establishment of the Royal Swedish Academy of Sciences.


Johann Friedrich Meckel the Younger was a German anatomist, biologist and professor of anatomy.
Meckel came from a family of physicians; his grandfather and father were physicians and anatomists and had their own anatomical museum at home. Meckel studied medicine at the universities of Halle and Göttingen, writing his doctoral dissertation on congenital anomalies of the heart. As a pathologist, he specialized in the study of congenital malformations and aspects of lung and blood vessel development. He also described Meckel's diverticulum, which he discovered during a pathologic examination, and became the founder of the science of teratology.
After Napoleon's occupation, the University of Halle reopened in May 1808, and Meckel was appointed professor of surgery, normal and pathological anatomy, and obstetrics. He taught throughout his life, continued to conduct research in pathology, and collected specimens for his collection. The scientist was the author of numerous articles and several multi-volume treatises, including one on pathologic anatomy and an atlas depicting human anomalies. His principal labors were devoted to the comparative morphology of vertebrates. In 1810 he completed the translation of Cuvier's (1769-1832) five-volume Leçons d'anatomie Comparée from French into German.
Meckel was a member of the German Academy of Naturalists "Leopoldina," a corresponding member of the Paris Academy of Sciences, and a foreign member of the Royal Society of London.

Samuel Thomas von Soemmering was a German physician, anatomist, anthropologist, paleontologist, physiologist and inventor.
He studied medicine at Göttingen, where he received his doctorate, and in the same year became professor of anatomy at Kassel, then at Mainz. Among Soemmering's contributions to biology are the discovery of the macula in the retina of the human eye, studies of the brain, lungs, nervous system, and embryonic malformations, and he published many papers in the fields of neuroanatomy, anthropology, and paleontology. He was the first to give a reasonably accurate account of the structure of the female skeleton.
Soemmering also worked on fossil crocodiles and pterodactyls, which at the time were called ornithocephalians. In addition, Soemmering dabbled in chemistry, astronomy, philosophy, and various other fields of science. Among other things, he investigated the refinement of wines and sunspots, and designed a telescope for astronomical observations. In 1809, Soemmering developed a sophisticated telegraph system based on electrochemical current, which is now preserved in the German Science Museum in Munich.
