Biography about Pascal

Blaise Pascal Pascal died when he was 39 years old, but, despite such a short life, he went down in history as an outstanding mathematician, physicist, philosopher and writer. A unit of pressure of Pascal and a programming language that are very popular today are named after him. Pascal's works cover a variety of areas. It is one of the creators of mathematical analysis, project geometry, probability theory, hydrostatics is widely known for the law of Pascal, according to which the changes in pressure in the resting liquid are transmitted to other points without changes, the creator of the mechanical counting device - “Paskalev Wheel”, as contemporaries said.

Pascal's philosophical thoughts after his death in different versions, under various names, published materials in the form of a book that is most often called “thoughts” influenced many outstanding people and, in particular, on the great Russian writers - I. Turgenev, F. Dostoevsky, L., some of the practical achievements of Pascal were awarded the highest distinction - today few people know the name of their author.

So, now very few will say that the most ordinary wheelbarrow is the invention of Blaz Pascal.

He also owns the idea of ​​omnibuses - publicly accessible carriages with fixed routes - the first type of regular city transport. Already at the age of sixteen, Pascal formulated the theorem about the hexagon, inscribed in the conical section of the Pascal Theorem. It is known that later he received from his theorem near the investigations. Blez Pascal was born in Clermont Ferrane on June 19.

Blaz was the third child in the family of a well -educated lawyer, carried away by mathematics. However, for unknown reasons, his father forbade him to study the exact sciences of up to 15 years. However, soon the ban was lifted: the young genius struck the parent, telling him that the sum of the corners in any triangle was equal to degrees. Well, how can you not introduce the child to Euclid after that?

Later, the father of the young Pascal was taken as a tax inspector. And the profession of the fundus involves a large number of calculations, which, of course, takes a lot of time even with a person who has known for mathematics. Blaz decided to simplify the life of the parent and took up the construction of the counting machine. The result of his work was the mechanical calculator "Pascalin", "trained" complexity and subtraction.

But Bleza Pascal’s scientific interests were not limited to the creation of a calculator: he found a common algorithm for finding signs of divisibility of any number for any other whole, a way of calculating binomial coefficients, formulated a number of basic regulations of elementary theory of probabilities. And he entered the history of physics by establishing the basic law of hydrostatics and confirming the assumption of the existence of atmospheric pressure.

Over the years, Pascal was more and more disappointed in abstract knowledge. In the years of the XVII century, he became close to representatives of Jansenism and soon went to the monastery. No, he did not accept the tonsure, but, having settled in a small monastery, he entered the polemic with the Jesuits. And he came out of it by the author of the masterpiece of French literature “Letters to the Provincial”.

Blaz Pascal created a mechanical computing device - a summarizing machine, which allowed to add numbers in the decimal number system. The son of the tax collector, Pascal decided to build a computing device, observing the endless tiring calculations of his father. In the year, when Pascal was 19 years old, he began to work on the creation of a summarizing car. Believing that this invention will bring good luck, father and son invested a lot of money in the creation of his device.

But the clerks opposed Pascal's accounting device - they were afraid to lose their jobs because of him, as well as employers who believed that it was better to hire cheap accounts than buying an expensive car. In this machine, the numbers of a six -digit number were set by the corresponding turns of wheels with digital divisions, and the result of the operation could be read in six windows - one for each digit.

The discs were mechanically connected, when added, the transfer of a unit in the next category was taken into account. The disk of units was associated with the disk of dozens, the disk of dozens - with the disk of hundreds, etc. If, when turning, the disk passed through zero, then the next disk turned a unit forward. Other operations were performed using a rather uncomfortable procedure for repeated additions, and this was the main drawback of the machine.

However, the principle of related wheels invented by Pascal was the basis on which most computing devices were built over the next three centuries. Blaz Pascal and another great Frenchman, Pierre Farm, became the founders of probability theory, and the year of birth of this theory is often called the year when Pascal and the Farm, independently of each other, gave the correct explanation of the so -called paradox of the bet section.

But perhaps the most popular mathematical work of Pascal is a treatise on the "arithmetic triangle" formed by binomal coefficients of the Pascal triangle and has the use in probability theory.But the remarkable curve of the 4th order of Pascal snail is named after Father Blaz Pascal Etienne, who combined public service with mathematics.
