He introduced the problem as follows: Nothing is more attractive to intelligent people than an honest, challenging problem, whose possible solution will bestow fame and remain as a lasting monument.

They were all descendants of Niklaus Bernoulli, a prominent merchant in the city of Basel. Each of these mathematicians was compelled by his parents to study for one of the established professions before being permitted to embark upon his real interest, mathematics.

Within the group there were four in particular who contributed to the theory of probability and mathematical statistics: Jakob i and Johann i The first in the line of the Bernoulli mathematicians, Jakob I —was the son of the merchant Niklaus. He completed theological studies and then spent six years traveling in England, France, and Holland.

Returning to Basel, he lectured on physics at the university until he was appointed professor of mathematics in His younger brother, Johann I —studied for a medical degree, at the same time receiving instruction in mathematics from Jakob.

The brothers were inspired by the works of Leibniz on the infinitesimal calculus, and they became his chief protagonists on the Continent. The new methods enabled them to solve an abundance of mathematical problems, many with applications to mechanics and physics.

They applied differentiation and Johann bernoulli essay to find the properties of many important curves: Jakob was particularly fascinated by the logarithmic spiral, which he requested be engraved on his tombstone. Both used infinite series as a tool; the Bernoulli numbers were introduced by Jakob.

Johann was perhaps even more productive as a scientist than was Jakob. He studied the theory of differential equations, discovered fundamental principles of mechanics, and wrote on the laws of optics. The personal relations between the brothers were marred by violent public strife, mainly disputes about priority in the discovery of scientific results.

Particularly bitter was their controversy over the brachystochrone, the curve of most rapid descent of a particle sliding from one point to another under the influence of gravity. The problem was of great theoretical interest, since it raised for the first time a question whose solution required the use of the principles of the calculus of variation the solution is a cycloid.

During his stay in Holland, Jakob became interested in the theory of probability. In his lifetime he published very little on the subject—only a few scattered notes in the Acta eruditorum.

It is divided into four books. The second gives a systematic presentation of the theory of permutations and combinations, and in the third this is applied to a series of contemporary games, some quite involved.

For each, Jakob computed the mathematical expectations of the participants. The fourth book shows the greatest depth. Here Jakob tried to analyze the events to which probability theory is applicable; in other words, he dealt with the basic question of mathematical statistics: He emphasized that a great number of observations are necessary.

This he did, with complete rigor and without the use of calculus, by examining the binomial probabilities and estimating their sums.

Illustrations with numerical computations for small intervals are given. The author concluded with some philosophical observations which show the importance he attached to his theorem. To the Ars conjectandi Jakob added a supplement on the jeu de paume similar to the game of tennisin the form of a letter to a friend.

Here he computed the chances of winning for a player at any stage of the game, given players with equal skill and players with differing skill, and in the latter cases he determined how great an advantage the more skilled one can allow the other.

True to the family tradition, Niklaus studied for one of the older professions, jurisprudence, while on the side he attended the lectures in mathematics of his two uncles. His law thesis straddled both fields: He accepted a professorship in mathematics at Padua in but disliked the university there and returned to Basel in In he was appointed professor of logic; in he changed to a chair of jurisprudence.Daniel Bernoulli was the son of Johann Bernoulli, a mathematician, and his brother Nicolaus and his uncle Jacob were also mathematicians.

Daniel was sent to Basel University at the age of 13 to study philosophy and logic. Johann Bernoulli Essay - On August 6, , a famous Swiss mathematician was born in Basel, Switzerland.

He was the tenth child of Nikolaus Bernoulli and Margaretha Schonauer (McElroy 31). Bernoulli Family. Jakob i and Johann i.

The Life of Johann Bernoulli By Cheryl Wagner Smith Prelude The ’s were an exciting time in the development of mathematics and science. In the early ’s John Napier () and Henry Briggs () developed. Johann Bernoulli soon discovered Euler's great potential for mathematics in private tuition that Euler himself engineered.

Euler's own account given in his unpublished autobiographical writings, see [ 1 ], is as follows soon found an opportunity to be introduced to a famous professor Johann Bernoulli.
