Mathematics Mechanics Physics Philosophy. Yet it was more than simply a popularization. Music was still emerging from the mixture of Pythagorean numerical mysticism and theological principles that had marked its rationale during the late medieval period.

The first two were reprinted along with two more in ; a fifth and last volume was published in They make an odd mixture, for some are important in their exposition of Enlightenment ideals, while others are mere polemics or even trivial essays.

It was clearly an article meant to be propaganda, for the space devoted to the city was quite out of keeping with the general editorial policy.

These collections of mathematical essays were a mixed bag, ranging from theories of achromatic lenses to purely mathematical manipulations and theorems.

Included were many new solutions to problems he had previously attacked—including a new proof of the law of inertia.

His concept of the limit did not seem to be any more clear to his contemporaries than other schemes invented to explain the nature of the differential.

This evaluation must be qualified. No doubt he sensed the power of mathematics. He was rather in the tradition of Descartes.

Space was the realization of geometry although, unlike Descartes. It was for this reason that he could never reduce mathematics to pure algorithms, and it is also the reason for his concern about the law of continuity.

It was for this reason that the notion of perfectly hard matter was so difficult for him to comprehend, for two such particles colliding would necessarily undergo sudden changes in velocity, something he could not allow as possible.

The mathematical statement is:. The application of mathematics was a matter of considering physical situations, developing differential equations to express them, and then integrating those equations.

Mathematical physicists had to invent much of their procedure as they went along. For every such first, one can find other men who had alternative suggestions or different ways of expressing themselves, and who often wrote down similar but less satisfactory expressions.

He used, for example, the word fausse to describe a divergent series. The word to him was not a bare descriptive term. There was no match, or no useful match, for divergence in the physical world.

Convergence leads to the notion of the limit; divergence leads nowhere—or everywhere. Here again his view of nature, not his mathematical capabilities, blocked him.

He considered, for example, a game of chance in which Pierre and Jacques take part. Pierre is to flip a coin. He considered the possibility of tossing tails one hundred times in a row.

Metaphysically, he declared, one could imagine that such a thing could happen; but one could not realistically imagine it happening. In other words, any given toss is influenced by previous tosses, an assumption firmly denied by modern probability theory.

Jacques and Pierre could forget the mathematics; it was not applicable to their game. Moreover, there were reasons for interest in probability outside games of chance.

It had been known for some time that if a person were inoculated with a fluid taken from a person having smallpox, the result would usually be a mild case of the disease, followed by immunity afterward.

Unfortunately, a person so inoculated occasionally would develop a more serious case and die. The question was posed: Is one more likely to live longer with or without inoculation?

There were many variables, of course. For example, should a forty-year-old, who was already past the average life expectancy, be inoculated?

What, in fact, was a life expectancy? How many years could one hope to live, from any given age, both with and without inoculation?

It was not, as far as he was concerned, irrelevant to the problem. Aside from the Opuscules , there was only one other scientific publication after that carried his name: Unfortunately, Euler was never trusted by Frederick, and he left soon afterward for St.

Petersburg , where he spent the rest of his life. The work was seen through the press by Voltaire in Geneva, and although it was published anonymously, everyone knew who wrote it.

Paris, France, 29 October , mathematics, mechanics, astronomy, physics, philosophy. Other scientific writings appeared in the form of letters to Joseph-Louis Lagrange in the Memoirs of the Turin Academy and in those of the Berlin Academy between and In addition, he left several unpublished works: He held the positions of sous-directeur and directeur in and respectively.

As an academician, he was in charge of reporting on a large number of works submitted to the Academy, and he sat on many prize juries. In particular, one may believe that he had a decisive voice concerning the choice of works about lunar motion, libration, and comets for the astronomy prizes awarded to Leonhard Euler , Lagrange, and Nikolai Fuss between and Later , he extended the former property to polynomials with complex coefficients.

These results induce that any polynomial of the n th degree with complex coefficients has n complex roots separate or not, and also that any polynomial with real coefficients can be put in the form of a product of binomials of the first degree and trinomials of the second degree with real coefficients.

The study concerning polynomials with real coefficients was involved in the first of three memoirs devoted to integral calculus published in , , , in connection with the reduction of integrals of rational fractions to the quadrature of circle or hyperbola.

Furthermore he considered another class of integrals, which included, where P is a polynomial of the third degree, an early approach to elliptic integrals whose theory was later started by Adrien-Marie Legendre.

In particular, he gave an original method, using multipliers, for solving systems of linear differential equations of the first order with constant coefficients, and he introduced the reduction of linear differential equations of any order to systems of equations of the first order.

He considered a system of two differential expressions supposed to be exact differential forms in two independent variables, which should be equivalent to two independent linear partial differential equations of the second order with constant coefficients.

He used the condition for exact differential forms and introduced multipliers leading to convenient changes of independent variables and unknown functions.

His solution involved two arbitrary functions, to be determined by taking into account the boundary conditions of the physical problem.

That gave rise to a discussion with Euler about the nature of curves expressing boundary conditions.

These works were continued by Lagrange and Laplace. One of them is the motion of a solid body around its center of mass.

First he separated the motion of the Earth attracted by the Sun and the Moon into two independent motions: Then applying his principle to the Earth, supposed to be a solid body of revolution about its polar axis called axis of figure , he established two differential equations of the second order giving the motion of the figure axis in space and a third one expressing angular displacement around the figure axis.

He also proved the existence of an instantaneous axis of rotation moving both in space and in the Earth, but close to the figure axis. They accounted for the observed motions of the axis: But, though in a memoir published in he extended his differential equations to an ellipsoid with three unequal axes, he failed to account for the empirical laws found by Jean-Dominique Cassini.

The position of the solid was defined by six functions of time: In the twenty-second memoir , he simplified his equations by using what is called principal axes of inertia as body-fixed axes.

He did not take part in the controversy raised by Clairaut about the Newtonian formulation of universal gravitation, but he tried to account for the discrepancy between theory and observation by a force acting complementarily in the vicinity of the Earth.

The unpublished manuscript of that lunar theory was deposited at the Paris Academy in May , after Clairaut had stated his successful calculation of the apsidal mean motion.

He resumed it from the end of on and then achieved an expression of the apsidal mean motion compatible with the observed value. His new theory was finished in January , but he did not submit it to the St.

Petersburg Academy of Sciences for the prize, because of the presence of Euler on the jury. Independent variable z is analogous to ecliptic longitude.

The first equation is formulated as where unknown function t is simply connected to radius vector of the projection; N is a constant, 1 — N being proportional to the apsidal mean motion; and M depends on the position of the body through the disturbing forces.

The whole system has to be solved by an iterative process; at each step, M is considered as a known function of z , and constant N is determined so that the differential equation in t could not have any solution increasing indefinitely with z.

In the theory, only the first step of the iterative process was performed, whereas further steps are necessary to obtain a good value of N.

These latter also contain interesting developments about lunar theory, some of them connected to the problem of the secular acceleration of the Moon.

Rousseau, to whom he remained devoted. Although he shared many of the goals of the other philosophes, his correspondence in particular with Voltaire consistently shows not only a refusal to jeopardize his career and freedom to remain in Paris but also an unflinching conviction that enlightenment must be a gradual and tactful process of persuasion rather than a series of attacks, whether open or anonymous.

In this work he provides a synthesis of his prior thought in epistemology, metaphysics, language theory, science, and aesthetics. However, his most important work is without doubt the Preliminary Discourse to the Encyclopedia.

However, he also attempts to provide a rational, scientific method for the mapping of human knowledge as well as a historical account of the evolution of human thought.

From that point on, his health became increasingly fragile. In his last years he wrote little, instead concentrating on his duties as permanent secretary of the French Academy.

He was also a pioneer in the study of partial differential equations. He was christened Jean Baptiste le Rond. The infant was given into the care of foster parents named Rousseau.

Jean was the illegitimate son of Madame de Tencin, a famous salon hostess, and Chevalier Destouches, an artillery officer, who provided for his education.

He became a barrister but was drawn irresistibly toward mathematics. A prize essay on the theory of winds in led to membership in the Berlin Academy of Sciences.

Two people especially claimed his affection; his foster mother, with whom he lived until he was 50, and the writer Julie de Lespinasse, whose friendship was terminated only by her death.

It concerns the problem of the motion of a rigid body. The principle states that, owing to the connections, this second set is in equilibrium.

Applying calculus to the problem of vibrating strings in a memoir presented to the Berlin Academy in , he showed that the condition that the ends of the string were fixed reduced the solution to a single arbitrary function.

His contributions are discussed in Thomas L. Science and the Enlightenment ; reprinted, The illegitimate son of the chevalier Destouches, he was named for the St.

He was abandoned by his mother on the steps of the baptistry of Saint-Jean-Le-Rond in Paris, from which he received his name.
