In 1700's, one of the most brilliant minds of physics, mathematics and medicine was born. Daniel Bernoulli was born into the family of the leading mathematician Johann Bernoulli on February 8, 1700. Since the beginning, Daniel Bernoulli was surrounded by mathematics and great talent from his father and his brother—also his archenemy—Jacob Bernoulli. Albeit, one would think his father would have given him plenty of support for being a mathematician, he didn't. Johann Bernoulli forced his son to study medicine for he believed that being a mathematician brought no good fortune; nevertheless, Daniel Bernoulli beat all odds. After convincing his father to give him a few lessons in mathematics, he became one of the greatest physicists of the century; publishing many discoveries.
During his tenure of medical studies, Daniel became interested in the work of William Harvey, On the Movement of Heat and Blood in Animals. Harvey suggested that the heart was like a pump that forced blood like fluid through the arteries. This findings marked the beginnings of Daniel's interest in fluid dynamics (Miller, 2011).
In 1720, he traveled to Venice to study medicine but ended up working in mathematics. After winning the annual contest at the Paris academy for an hourglass that would continue to give the exact hour even under constant movement, Bernoulli was invited to Saint Petersburg by Catherine I of Russia. According to Allali and Bui, the next few years in Russia would be his most prosperous and productive. For instance, he worked with Leonhard Euler and helped him discover the Euler-Bernoulli beam theory. The theory was a simplified version of the linear theory of elasticity. It provided the means to calculate the load carrying and deflection characteristics of beams. Moreover, with Euler he continued to study the flow of fluids; specifically, they wanted to understand the relationship between the speed at which the blood flows and its pressure. Daniel experimented by puncturing the wall of a pipe with and open ended straw. Then by measuring the height the fluid rose, he discovered the height was related to the fluid's pressure. Soon, all over Europe, physicians were puncturing their patients arteries to measure blood pressure; the practice wasn't replaced until 170 years later by the modern method (Miller, 2012).
While studying vibrating systems, he defined simple nodes and frequencies of a system in oscillation; he demonstrated that the strings of musical instruments moved in an infinite number of harmonic vibrations all along the string. From 1725 to 1749, Daniel won 10 prizes from the Paris Academy of Sciences for his work in magnetism, tides, ocean currents, gravity, astronomy, and the behavior of ships at sea. (Bui & Ali, 2011).
In 1738, he published “Hydrodynamica” which was a milestone in the theory of fluid dynamics. His main work was based in the principle of conservation of energy, which he studied with his dad, although this time...
