The extraordinary legacy of the Bernoulli family.
The Bernoulli family was a remarkable dynasty of Swiss mathematicians and physicists who made significant contributions to various fields of science in the 17th and 18th centuries. The family produced 8 prominent academics, most notably Jacob, Johann, and Daniel Bernoulli, who were among the pioneers of calculus, differential equations, probability theory, and fluid mechanics.
