Joseph-Louis Lagrange was a mathematician and astronomer from the eighteenth century. Lagrange was not very interested in mathematics in his early life. It was not until he was a teenager that he became involved with mathematical study. He became curious about mathematics when he read a copy of Edmond Halley's 1693 work on the use of algebra in optics. Joseph-Louis Lagrange was one of the most renowned mathematicians in the eighteenth century. He contributed greatly to the progression of mathematics.

Joseph-Louis Lagrange was born in Turin, Italy on January 25, 1736 to Giuseppe Francesco Lodovico Lagrangia and Teresa Grosso. He was the eldest of eleven children, but one of only two to live to adulthood. Lagrange studied at the college of Turin. At first, his favorite subject was classical Latin. He later developed an interest in mathematics when he was around seventeen. Without the aid of the top mathematics of his time, Lagrange taught himself.

Lagrange published his first mathematical work on July 23, 1754. The paper described an analogy between the binomial theorem and the successive derivatives of the product of functions (O'Connor). After this, Lagrange began working on the tautochrone, the curve on which a weighted particle will always arrive at a fixed point in the same time independent of its initial position (O'Connor). He discovered a method of maximizing and minimizing functionals in a way similar to finding extrema of functions (Mathematical Thought). These discoveries would be major contributions to the new subject of the calculus of variations. This subject was beginning to be studied by mathematicians, but it was not called 'calculus of variations' until Leonhard Euler gave it the name. He se...

Near the end of his life, he published two more volumes of calculus lectures, one in 1797 and the other in 1800. Lagrange was named to the Legion of Honor and Count of the Empire in 1808 by Napoleon (Seikali). He received the Grand Croix of the Ordre Imperial de la Renuion award in April 3, 1813. (O'Connor). He died in Paris on April 10, 1813.

Joseph-Louis Lagrange was considered one of the greatest mathematicians of his time. By 1761, he was considered and described as the foremost mathematician living (Ball). He helped to advance a variety of branches of mathematics. He contributed to the fields of differential equations, number theory, and the calculus of variations. He also applied problems in dynamics, mechanics, astronomy, and sound. Lagrange was a very accomplished mathematicians, and he greatly influenced mathematics.

John did not actually go to formal school until he was at age thirteen, which he attended St. Andrews University. He only went to the university for a brief amount of time and left before he could even achieve his degree. Napier later went on to another educational institute to receive his higher studies. John was an expert in arithmetic and mathematics, which are the fields he made many contributions to. John Napier’s greatest discovery or invention is considered to be Naperian logarithm, which is often used to mean the natural logarithm.

Since Hilbert’s study in 1900 on mathematical problems, his questions have influenced mathematics still today. (Jeremy Gray) David Hilbert was born on 23rd January, 1862, Konigsberg, Germany. He attended the University of Konigsberg in the year 1880 to 1885, gymnasium of Wilhelm in the year 1879 to 1880 and Friedricskolleg gymnasium in the year 1872 to 1879. Some of the books that David Hilbert wrote include; statistical mechanics, theory of algebraic number fields, the foundations of geometry and principles of mathematical logic. Hilbert’s 23 mathematical problems were more than just a collection of mathematical problems because he outlined problems that addressed his mathematical philosophy.

His propensity for higher learning was so great that he studied with Johann Bernoulli, who was Jakob’s brother, as a young boy. His time with Johann urged his sense of mathematic discovery. Euler attended University of Basel where he earned his Master’s degree while he was still a teenager. While at the school he barely learned any mathematics because the school was basically a poor school. Due to his own mathematic curiosity and Johann’s private lessons, at the under-ripened age of 16, Euler became a college graduate with a Master’s degree.

He discovered exponential calculus, and co-discovered, with his brother, calculus of variations (Olanoff 612). He also used math in topics such as astronomy, optics, ships' sails, and the tides of oceans. In all, Bernoulli was a very interesting person who contributed to the math used today (Jones 211).

Recognizing his talent, his youthful studies were accelerated by the Duke of Brunswick in 1792 when he was provided with a stipend to allow him to pursue his education. In 1795, he continued his mathematical studies at the University of Gö ttingen. In 1799, he obtained his doctorate in absentia from the University of Helmstedt, for providing the first reasonably complete proof of what is now called the fundamental theorem of algebra. He stated that: Any polynomial with real coefficients can be factored into the product of real linear and/or real quadratic factors. At the age of 24, he published Disquisitiones arithmeticae, in which he formulated systematic and widely influential concepts and methods of number theory -- dealing with the relationships and properties of integers.

His father, Simon Jacobi, was a banker and his older brother, Moritz von Jacobi, was an engineer and later a physicist. As you can tell, part of his family was involved in mathematics before he even started. He was mostly taught by his uncle Lehman and by the age of 12 he went to the Potsdam Gymnasium where he was schooled. Although he was very young, after almost half of a year, Jacobi was promoted to the senior class because of his knowledge and learning abilities. He received high awards for his knowledge and perseverance in Latin, Greek, and history yet he excelled at mathematics.

He discovered what we now call Bode's Law, and the principle of squares, which we use to find the best fitting curve to a group of observations. Having just finished some work in quadratic residues in 1795, Karl Gauss moved to the University to access the works of previous mathematicians. He quickly began work on a book about the theory of numbers, which is seen as his greatest accomplishment. This book was a summary of the work that had been established up to the time, and contained questions that are still relevant today. While at the University in 1796, he discovered that a 17-sided polygon could be inscribed in a circle with only the tools of a compass and a ruler.

Cayley, who had a family of English ancestry, lived in St. Petersburg, Russia during his childhood where he attended his first years of schooling. In 1835 he began attending King’s College School in England because of his promise as a mathematician. After Cayley became a lawyer and studied math during his spare time, publishing papers in various mathematical journals. These journals were later looked at by Archibald and in a paper published in 1900 in Strasbourg he gave Cayley the honor of having the curve named after him. Cayley’s Sextic The polar form of the equation for the curve, Cayley’s Sextic, is shown as: r = 4a cos^3 (q/3).
