Questions about Jacob Bernoulli

Short answers, pulled from the story.

When was Jacob Bernoulli born and where did he enter the world?

Jacob Bernoulli entered the world in 1655 within the Swiss Confederation. He died in 1705 at the age of 50 years and 7 months.

What mathematical constant did Jacob Bernoulli discover while studying compound interest questions?

Jacob Bernoulli discovered a fundamental constant now known as e based on his initial findings regarding force of interest. Euler later named this number e after Bernoulli calculated that continuous compounding reaches $2.7182818....

Which book published posthumously introduced the term Bernoulli trial to probability theory?

Ars Conjectandi appeared in Basel in 1713, eight years after his death. The term Bernoulli trial resulted directly from this specific work which covers combinatorics and uses Bernoulli numbers in discussions of exponential series.

How did Jacob Bernoulli contribute to the development of differential equations between 1690 and 1696?

In May 1690, Jacob Bernoulli showed that determining the isochrone equates to solving a first-order nonlinear differential equation. By 1696, he solved what we now call the Bernoulli differential equation.

Why was a logarithmic spiral engraved on Jacob Bernoulli's tombstone instead of an Archimedean one?

Jacob Bernoulli requested a logarithmic spiral be engraved on his tombstone along with the motto Eadem mutata resurgo to symbolize fortitude and constancy in adversity according to his writings. An Archimedean spiral was engraved instead of the intended logarithmic one.
