  1. Apr 11, 2024 · Euler’s mathematical ability earned him the esteem of Johann Bernoulli, one of the first mathematicians in Europe at that time, and of his sons Daniel and Nicolas. In 1727 he moved to St. Petersburg, where he became an associate of the St. Petersburg Academy of Sciences and in 1733 succeeded Daniel Bernoulli to the chair of mathematics.

    Johann tried to map out Daniel's life, selected a wife for him and decided he should be a merchant. Strangely enough, his own father had tried a similar strategy but Johann had resisted - so did Daniel. However, Daniel spent considerable time with his father and learned much about the secrets of the Calculus which Johann had exploited to gain his f...

    By the age of 23, Daniel was in Padua, Italy. Whilst recovering from illness he designed a ship's hour glass which would produce a reliable trickle of sand even in stormy weather. He submitted his design to the French Academy and took first prize. Meanwhile a friend, Christian Goldbach, arranged for some of Daniel's other work to be published under...

    When he was 25, Daniel returned home to Basel to find a letter from Empress Catherine I of Russia awaiting him, inviting him to become professor of mathematics at the Imperial Academy in St. Petersburg. At first Daniel was not keen to travel to such a distant land, but his elder brother Nikolas offered to go with him. Catherine was so keen to secur...

    Together Bernoulli and Euler tried to discover more about the flow of fluids. In particular, they wanted to know about the relationship between the speed at which blood flows and its pressure. To investigate this, Daniel experimented by puncturing the wall of a pipe with a small open ended straw and noted that the height to which the fluid rose up ...

    Taking his discoveries further, Daniel Bernoulli now returned to his earlier work on Conservation of Energy. It was known that a moving body exchanges its kinetic energy for potential energy when it gains height. Daniel realised that in a similar way, a moving fluid exchanges its kinetic energy for pressure. Mathematically this law is now written: ...

    By the age of 30 Daniel's father had just been awarded a prize by the French Academy. Daniel himself had almost completed his treatise Hydrodynamicaand longed to return to Basel. Despite numerous attempts Daniel repeatedly lost out in ballots for academic positions in Basel but two years later he finally succeeded. He returned home in 1734 to disco...

  4. M.B.W. Tent suggested, in her fictionalized account of the lives of Euler and the Bernoullis, [12] that the elder Waldkirch wanted someone trained in mathematics, since he had learned that the mathematician Girolamo Cardano (1501-1576) had been involved in teaching literacy to the blind.

  5. Dec 24, 2016 · Euler was given the opportunity to attend private lectures by Johann Bernoulli, who recognized Euler’s extraordinary potential in mathematics. At the age of 18, Euler began his own investigations on mechanics and mathematics.

  6. The year 1727 marked an important historical moment when, shortly after Isaac Newton died, Leonhard Euler began his distinguished career in Saint Petersburg. In mathematics at the start of the Enlightenment, many expected few major new achievements or fundamental innovations.
