His tutor replied that it was the science of constructing exact figures and of determining the proportions between their different parts. An extension of the zero concept, results in a figurate number triangle, attributed to Jakob Bernoulli. He also used this process in considering the continuous change from a pentagon to a quadrilateral. If two pairs of opposite sides are parallel, then all three pairs of opposite sides form pairs of parallel lines and there is no Pascal line in the Euclidean plane in this case, the line at infinity of the extended Euclidean plane is the Pascal line of the hexagon. Two of the results are important as well as interesting.

If two pairs of opposite sides are parallel, then all three pairs of opposite sides form pairs of parallel lines and there is no Pascal line in the Euclidean plane in this case, the line at infinity of the extended Euclidean plane is the Pascal line of the hexagon. A cycloid is defined as the curve produced by the locus of points of a point on the circumference of a circle which rolls along a straight line. This proof proves the theorem for circle and then generalizes it to conics. The only mathematical work that he produced after retiring to Port Royal was the essay on the cycloid in Thus if the first player gain, then 64 pistoles belong to him, and if he lose, then 32 pistoles belong to him. Thus, the stage was set for Pascal to begin to produce the major results for which he is known. However, for a considerable part of his life, Pascal turned away from worldly issues and devoted his life to God, in which he developed a reputation as a master of prose through his religious writings Orcibal 1.

The discovery of certainties within that large uncertainty, to which Pascal made an essential contribution, deserves to rank as one pascls the triumphs of the human intellect.

He recorded his own solutions in letters to Carcavi. In dealing with problems of the cycloid, Pascal had to replace the characteristic property of the parabola with that of the cycloid to achieve an analogous sum in order to calculate areas pasals volumes Kline Perhaps as a mathematician Pascal is best known in connection with his correspondence with Fermat in in which he laid down the principles of the theory of probabilities.

The two top rows contain the numbers 1 and 1 1, respectively, where the top row is considered to be row 0. At the age of fourteen he was admitted to the weekly meetings of Roberval, Mersenne, Mydorge, and other French geometricians; from which, ultimately, the French Academy sprung.

His various contacts with illness and death from on, and his own near death in a carriage accident late intogether with the influence of a morbidly religious sister, turned him toward the Jansenist version of Pascalx. Pascal was also an early investigator of the physical world.

The second, which is really due to Desargues, is that if a quadrilateral be inscribed in a conic, and a straight line be drawn cutting the ob taken in order in the points ABCand Dand the conic in P and Qthen PA.

The Cayley—Bacharach theorem is also used to prove that the group operation on cubic elliptic curves is associative. Therefore, the risk of belief will be accepted by the wise and sober gambler, in the earthly casino in which his life is set.

It is named after Blaise Pascal.

The answer is obtained using the arithmetical triangle. Their scores and the number of points which constitute the game being given, it is desired to find in what proportion they should divide the stakes. The problem was this.

Pascal’s last mathematical gesturelike his first, was geometrical: Pascal is one of the most brilliant, and most tormented, figures in the history of mathematics. This naturally excited the boy’s curiosity, and one day, being then twelve years old, he asked in what geometry consisted. From his 14th year he was included in the Mersenne circle in Paris, and his first original mathematical discovery, which laid the foundations of projective geometry, was communicated to that group when he was However, at times Pascal also argued that the heart intervenes to assure us of the correctness of mathematical steps.

This configuration of 60 lines is called the Hexagrammum Mysticum. If a projection is formed of Figure 1 from a point outside the plane and then a section of this projection, the section will contain a conic and a hexagon inscribed in it.


This means that when n is fixed and r runs from 0 to n, the successive binomial coefficients are obtained.

Pascal’s theorem

That of Fermat is given later. His father, a local judge at Clermont, and himself of some scientific reputation, moved to Paris inpartly to prosecute his own scientific studies, partly to carry on the education of his only son, who had already displayed exceptional ability.

His correspondence with Fermat about this time shews that he was then turning his attention to analytical geometry and physics. It is only fair to add that no one had more contempt than Pascal for those who changes their opinions according to the ocnic of material benefit, and this isolated passage is at variance with the spirit of his writings.

Let us then divide these 32 pistoles equally, and give me also the 32 pistoles of which I am certain. To find any number in subsequent rows, add the two numbers above it.

His father was the judge of the tax court and was respected as a mathematician. Against that cosmic uncertainty, Pascal at least comes off better than Einstein. It was formulated by Blaise Pascal in a note written in when he was 16 years old and published the following year as a broadside titled ” Essay povr les coniqves.

Mathematical Thought from Ancient to Modern Times. Blaise Pascal Conic sections Theorems in projective geometry Theorems in plane geometry Theorems in geometry Euclidean plane geometry. At the age of sixteen, Blaise Pascal wrote an Essay on Conics that so greatly impressed Descartes that he could not believe that it had been written by someone esway young Kline Thus the group operation is associative.

Inat the age of eighteen, Pascal constructed the first arithmetic machine to help his father with tax computations.
