(February 8, 1700 – March 17, 1782)
Daniel is a prominent member of the renowned Bernoulli family, which produced generations of brilliant mathematicians. He with his father, Johann, brother Nikolaus, and uncle, Jacob, are the most outstanding geniuses of that Swiss family. He was also a friend of Leonhard Euler (another Swiss who is widely regarded as the greatest of all the mathematicians). Although Daniel excelled in mathematics, his father insisted that he study biology. That was the reason why he earned his PhD in anatomy and botany. But as soon as he became independent from his dad, he settled for maths (which came naturally to the Bernoullis). After pioneering works in statistics, he turned to mathematical physics where he made inaugural discoveries in fluid dynamics. His acclaimed Bernoulli Principle (including his Bernoulli’s Equation), was first presented in the Hydrodynamica treatise he published in 1738. Clever and meticulous, Daniel won the grand prix of the Paris Science Academy 10 times (between 1725 and 1749): for works spanning across astronomy, gravitation, magnetism and oceanography. His other works pertained to thermodynamics, kinetic theory, resonance and wave propagation. As an early proponent of mathematical physics, Daniel Bernoulli explored many areas of applied maths: making far-reaching contributions. For example, one of his treatises (titled Exercitationes quaedam Mathematicae) was about using differential equations to tackle various problems in fluid mechanics. And exactly 50 years after his Hydrodynamica was published, Joseph-Louis Lagrange emulated its pattern (as a model) in publishing his own masterpiece: Mécanique Analytique. Daniel Bernoulli’s name is immortalized in several maths and physics concepts.
