Daniel bernoulli's research field is very extensive, and his work almost involved the frontier problems of mathematics and physics at that time. In pure mathematics, his work involves algebra, calculus, series theory, differential equations, probability theory and so on, but his best job is to apply calculus and differential equations to physics and study fluid problems, vibration and oscillation of objects. He is regarded as the founder of mathematical physics methods.
Daniel 17 13 began to study philosophy and logic, 17 15 got a bachelor's degree, and 17 16 got a master's degree in art. During this period, his father, especially his brother Nicolaus Bernoulli II (1695- 1726) taught him to study mathematics, which made him influenced by his math family. His father tried to make him a business apprentice and find a business career, but the idea failed. So he was sent to study medicine. At first, he went to Heidelberg, Basel. 17 18, 6436 1720, and he returned to Basel. 172 1 thesis defense, obtained the medical doctorate. His thesis is entitled "Breathing". In the same year, he applied for the professorship of anatomy and botany in university of basel, but failed. 1723, Daniel went to Venice. 1724, he published his exercise Mathematica e in Venice, which attracted many people's attention and was invited to work in the Academy of Sciences in Petersburg. 1725, he returned to Basel. Later, he and his brother Nicholas accepted the invitation of Petersburg Academy of Sciences. He works in the Academy of Sciences in Petersburg. During his eight years in Petersburg (1725— 1733), he was appointed as an academician of physiology and mathematics. From 1727, he worked with L. Euler, who initially served as Daniel's assistant and later took over Daniel's position as a mathematics academician. During this period, Daniel taught medicine, mechanics and mathematics. He did a lot of work to show his creativity. However, due to the sudden death of his brother Nicholas II and the bad weather, he returned to Basel on 1733. In Basel, he first became a professor of anatomy and botany, 1743 became a professor of physiology, and 1750-65438 became a professor of physics.
After Daniel left Petersburg on 1733, he began the most acclaimed scientific exchange with Euler. In the communication, Daniel provided the most important scientific information for Euler, and Euler used his excellent analytical ability and rich work experience to give him the fastest help. They communicated for 40 years, and the most important communication was between 1734- 1750. They are.
Daniel's academic works are very rich. He has written more than 80 books and papers on mathematics and mechanics. 1738, he published the most important book in his life, Fluid Mechanics A. During the 30 years from 1725- 1757, he engaged in astronomy (1734) and gravity (65438). Magnetism (1743, 1746), ocean current (1748), ship navigation stability (1753, 1757), vibration theory (1747) He and his father, John, put "the reasons for the different angles between planetary orbits and the equator of the sun" (Quelle est al cause physique de l 'Inclinaison des plans des orbiters des PLA-nè tes Parr Rapport au plan de lé quateur de la ré vol). The masterpiece "Axe of the Sun" (1734) won the double prize of Paris Academy of Sciences. Daniel's number of awards can be compared with that of the famous mathematician Euler, so he is loved by European scholars. 1747 became an academician of Berlin Academy of Sciences, and 1748 became an academician of Paris Academy of Sciences. 1750 was elected as a member of the royal society. He is also a member of the academies or societies of science in Bologna (Italy), Bern (Switzerland), Turin (Italy), Zurich (Switzerland) and Munich (Germany). He still retained the title of academician of Petersburg Academy of Sciences during his lifetime.
