Jakob Bernoulli

1654 - 1705

Jakob Bernoulli was the first of long series of Bernoulli family members, all mathematicians, whose combined contributions to mathematics and physics is unequalled in history.

• Experiments/Discoveries
• Bernoulli discovered the constant \$e\$, often referred to as Euler's number: \$e = {lim}↙{n→∞}(1+1/n)^n\$

Jakob planted the family tree in Basel, Switzerland. He travelled extensively, and was a contemporary of Roberts Boyle and Hooke. He took the side of the German Gottfried Leibniz against Isaac Newton in the infamous dispute over the invention of calculus. Jakob developed calculus further, together with his younger brother Johann.

The two brothers were among the earliest to develop and champion the calculus of Leibniz, published in 1684. Jakob's initial collaboration with his brother Johann turned to destructive rivalry as the latter sought to exit the shadow of elder brother.

Quote of the day...

It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.
