Blaise Pascal Biography

Blaise Pascal, a mathematician, invented the Pascaline calculator, an early calculator, in the 1640s, establishing Evangelista Torricelli's theory about the source of barometrical variations. Pascal and Pierre de Fermat founded probability theory in the 1650s, and in the same year, he produced Les Provinciales, a groundbreaking series of letters defending his Jansenist faith. Pascal is also known for the Pensées, a collection of notes published after his death. His father, a tax collector in Rouen, educated him as a child prodigy. Pascal's first mathematical work was on conic sections, and at the age of 16, he authored an important dissertation on the subject of projective geometry. Later, he corresponded with Pierre de Fermat about probability theory, which had a significant impact on the development of social science and modern economics.

He began pioneering work on calculating devices (named Blaise Pascal calculator and later Pascalines) while still a teenager in 1642, establishing himself as one of the first two creators of the mechanical calculator. Pascal, like his colleague Rene Descartes, was a natural and applied science pioneer. Pascal defended the scientific method and produced some contentious results. By generalising the work of Evangelista Torricelli, he made significant advances to the science of fluids and clarified the notions of pressure and vacuum. In 1647, he rebutted Aristotle and Descartes, who claimed that nature abhors a vacuum, following Torricelli and Galileo Galilei.

Life History

Pascal, the third of four children and the only son of Etienne and Antoinette Pascal, was born on June 19, 1623, in Clermont-Ferrand, France. Pascal's mother died while he was a child, and he grew up to be quite close to his two sisters, Gilberte and Jacqueline. Etienne, his father, was a tax collector and gifted mathematician. Etienne moved the family to Paris in the year of 1631. He'd opted to homeschool Pascal, a young prodigy, so he could create an unconventional curriculum and ensure that Pascal could explore his natural curiosity. Pascal is also thought to have received his education at home due to health reasons. Etienne, ironically, left mathematics out of his son's early education because he was worried that Pascal would become so engrossed in geometry that he wouldn't be able to concentrate on classical subjects.

Pascal's education began with a focus on languages, particularly Latin and Greek. Even then, Etienne's scheme backfired: the fact that mathematics was a banned subject piqued the attention of the inquisitive child, who began investigating geometry on his own at the age of 12. He made up his language because he didn't know any formal mathematical jargon, and figured out that the sum of a triangle's angles equals two right angles very quickly. During the Fronde, the Pascal family (Blaise, Etienne, and Jacqueline) left Paris again, but they returned later that year to a new location in the French city. Mazarin and the regent reached an agreement with the parlement to terminate the Fronde, which made Étienne's job as a tax collector in Rouen obsolete. Within a few years of his return to Paris, Blaise Pascal experienced a significant change in the emotional and nursing support he had had throughout his childhood. Gilberte, his oldest sister, had married Florin Périer and relocated to Clermont-Ferrand in June 1641. 

Blaise Pascal Education

His only formal education was in classical languages and mathematics, and he never received any formal training in theology or school philosophy. Pascal's decision to educate himself at home was influenced by the fact that he had been in terrible health since he was two years old.

Mystic Hexagram and Religious Conversion

Pascal's father allowed him to read the writings of ancient Greek mathematician Euclid in response to his unwavering fascination. Etienne also permitted Pascal to join him at Mersenne's Academy in Paris for meetings. Pascal presented a number of his early theorems, notably his Mystic Hexagram, to some of the most prominent mathematical intellectuals of the period there when he was 16 years old. After a period of political turmoil, the Pascal family decided to stake their claim once more in 1640. They relocated to Rouen, France, where Pascal's father had been hired as a tax collector the previous year. 

Pascal's first written work, Essay on Conic Sections, was published in 1640. The papers were a significant step forward in projective geometry, which entailed projecting a three-dimensional object onto a two-dimensional field. Etienne was severely hurt in a fall in 1646, resulting in a shattered hip that rendered him housebound. The Pascals had never fully adopted local Jesuit views, therefore the accident caused a shift in their religious convictions. Following Etienne's accident, he was visited by two brothers who were also members of Jansenism, a Catholic denomination.

Blaise Pascal Inventions and Discoveries

Pascal Pascal began work on the Pascaline calculator in 1642, spurred by the desire to make his father's job of calculating taxes easier. (An earlier version of the calculator was invented and manufactured in 1623 by German polymath William Schickard.) A number wheel calculator with moveable dials, each representing a numerical digit, was known as the Pascaline. However, the invention was not without flaws: there was a mismatch between the design of the calculator and the structure of French currency at the time. Blaise Pascal continued to improve the device, and by the 1652 year, he had produced 50 prototypes, but the Pascaline was never a big seller.

Mathematical and Scientific Achievements:

Pascal's father had become a tax collector for Rouen, France, by 1642. Pascal created the Pascaline calculator to assist his father. This mechanical calculator included a number wheel with movable dials and could add and subtract. The calculator couldn't handle the French currency because there were 20 sols in a livre and 12 deniers in a sol at the time. Although his calculator was not a commercial success, Pascal continued to modify and improve it for ten years. Pascal made contributions to hydrostatics in the 1640s. Fluids at rest are studied in this section of fluid mechanics. He invented the syringe and the hydraulic press as a result of his experiments.

Pascal experimented with different air pressures. He backed up Evangelista Torricelli's notion of what causes barometer changes. He published “New Experiments Concerning Vacuums” in 1647 after proving the existence of a vacuum to his satisfaction.

Pascal's Other Works

His theoretical study on fluid equilibrium led to the publication of his treatise “Treatise on the Equilibrium of Liquids” in 1653, which described Pascal's law of pressure. According to the Pascal principle, any rise in pressure at any place in a confined fluid causes an equal increase in pressure at all other points in the container. Pascal also explored conic sections and developed key projective geometry theorems. His work on cones, titled "Generation of Conic Sections," began in 1648 and was not completed until 1653/4. He also looked into the Pascal Triangle, making many new mathematical discoveries. Each number in this triangle is the sum of the two numbers just above it. 

Pascal's Identity was proven using the triangle. This is a helpful comb theorem that deals with binomial coefficients. In the year 1653, he published “Traite du triangle arithmetic” (“Treatise on the Arithmetical Triangle”). Pascal first corresponded with mathematician Pierre de Fermat in 1654. He experimented with dice and determined that the probability of a given outcome was set. This was the birth of probability theory. Today, Fermat and Pascal are credited with co-founding probability theory. In his attempt to develop the perpetual motion machine, Pascal accidentally invented the roulette wheel, which is now a well-known gaming gadget.

How Did Blaise Pascal Die?

Pascal became unwell with an unknown ailment when he was barely a year old. His stomach bloated, and he started having violent fits in which he thrashed around in his bed. Blaise Pascal died of this ailment while he was only 39 years old.
