Blaise Pascal French mathematician and philosopher who left many important results in mathematics, physics, and literature. He began to work on geometry at the age of 12, and wrote a paper on projective geometry when he was 16. Thus mathematics became one of his major fields of study. When he was 19 years old, he invented a mechanical calculator, called "Pascaline". A small number of machines were actually manufactured but only a few were sold. In 1653, he worked on hydrostatics and wrote Treatise on the Equilibrium of Liquids which contains Pascal's Law of pressure. Then in 1654, his correspondence with Fermat prepared the ground for mathematical theory of probability. Later, in his religious essay, he applied a game theoretic consideration to his apologetic argument for the existence of God (Pascal's wager). In 1654 also, his Treatise on the Arithmetical Triangl was completed. Pascal's triangle is the following figure: This figure is related to the binomial expansion of (a+b)(a+b) ..., and the numbers in the figure are nothing but binomial coefficients in a certain order: For instance, "2" in the third line is a sum of the two numbes "1" and "1" immediately above, and likewise "3" in the fourth line is a sum of "1" and "2" immediately above. This triangle has various applications to mathematical problems, including probability and games.

Back to Modern History Sourcebook Modern History Sourcebook: Blaise Pascal Penseés ( Thoughts Translation: W.F. Trotter, Introductory Note Blaise Pascal was born at Clermont in Auvergne on June 19, 1623, the son of the president of the Court of Aids of Clermont. He was a precocious child, and soon showed amazing mathematical talent. His early training was scientific rather than literary or theological, and scientific interests predominated during the first period of his activity. He corresponded with the most distinguished scholars of the time, and made important contributions to pure and applied mathematics and to physics. Meantime, an accident had brought the Pascal family into contact with Jansenist doctrine, and Blaise became an ardent convert. Jansenism, which took its name from Jansenius, the bishop of Ypres, had its headquarters in the Cistercian Abbey of Port-Royal, and was one of the most rigorous and lofty developments of post-Reformation Catholicism. In doctrine it somewhat resembled Calvinism in its insistence on Grace and Predestination at the expense of the freedom of the will, and in its cultivation of a thoroughgoing logical method of apologetics. In practise it represented an austere and even ascetic morality, and it did much to raise the ethical and intellectual level of seventeenth century France. Jansenism was attacked as heretical, especially by the Jesuits; and the civil power ultimately took measures to crush the movement, disbanding the nuns of Port-Royal, and by its persecutions affording to many of the Jansenists opportunities for the display of a heroic obstinacy. In this struggle Pascal took an important part by the publication, under the pseudonym of "Louis de Montalte," of a series of eighteen letters, attacking the morality of the Jesuits and defending Jansenism against the charge of heresy. In spite of the fact that the party for which he fought was defeated, in these "Provincial Letters," as they are usually called, Pascal inflicted a blow on the Society of Jesus from which that order has never entirely recovered.

Antecipamos o futuro que nos tarda, como para lhe apressar o curso; ou evocamos o passado que nos foge, como para o deter: tão imprudentes, que andamos errando nos tempos que não são nossos, e não pensamos no único que nos pertence; e tão vãos, que pensamos naqueles que não são nada, e deixamos escapar sem reflexão o único que subsiste. É que o presente, em geral, fere-nos. Escondemo-lo à nossa vista porque nos aflige; e se nos é agradável, lamentamos vê-lo fugir. Tentamos segurá-lo pelo futuro, e pensamos em dispor as coisas que não estão na nossa mão, para um tempo a que não temos garantia alguma de chegar. Examine cada um os seus pensamentos, e há-de encontrá-los todos ocupados no passado ou no futuro. Quase não pensamos no presente; e, se pensamos, é apenas para à luz dele dispormos o futuro. Nunca o presente é o nosso fim: o passado e o presente são meios, o fim é o futuro. Assim, nunca vivemos, mas esperamos viver; e, preparando-nos sempre para ser felizes, é inevitável que nunca o sejamos. Blaise Pascal, in "Pensamentos"

1640 AD Blaise Pascal's Arithmetic Machine As fate would have it, determining who invented the first mechanical calculator is somewhat problematical. Many references cite the French mathematician, physicist, and theologian, Blaise Pascal as being credited with the invention of the first operational calculating machine. Blaise Pascal. a Pascal's Arithmetic Machine. Courtesy of IBM In 1640, Pascal started developing a device to help his father add sums of money. The first operating model, the Arithmetic Machine, was introduced in 1642, and Pascal created fifty more devices over the next ten years. (In 1658, Pascal created a scandal when, under the pseudonym of Amos Dettonville, he challenged other mathematicians to a contest and then awarded the prize to himself!) a However, Pascal's device could only add and subtract, while multiplication and division operations were implemented by performing a series of additions or subtractions. In fact the Arithmetic Machine could really only add, because subtractions were performed using complement techniques, in which the number to be subtracted is first converted into its complement, which is then added to the first number. Interestingly enough, modern computers employ similar complement techniques. a See also: Leonardo da Vinci's mechanical calculator John Napier and Napier's Bones Wilhelm Schickard's mechanical calculator Gottfried von Libniz's Step Reckoner ...

Pascal, Blaise (16231662) Pascal was born in France and was encouraged by his father to study science. He met Fermat and was inspired to work on applied science problems. As early as 1640, he wrote an essay on conic sections and earned praise for his work from Descartes Even though he suffered from poor health, Pascal designed an "arithmetic machine" to perform computations for tax collecting. He completed the first operating model in 1642 and built fifty more during the next decade. The machine was a small box with eight dials, each geared to a drum that displayed the digits in a register window. Pascal also contributed to the development of differential calculus Later, he became interested in the physics of fluids under pressure and other components and concepts of hydrostatics. After poor health adversely affected his pursuits in science, Pascal became interested in games of chance. This led to his study of probability and his contributions to the foundations of the calculus of probability. Poor health and interest in religious affairs kept him from pursuing mathematics full time; however, he still continued to produce important mathematical results in geometry and algebra.

Studying under the direction of his father, a civil servant, Pascal showed great precocity, especially in mathematics and science. Before he was 16 he wrote a paper on conic sections which won the respect of the mathematicians of Paris; at 19 he invented a calculating machine. Credited with founding the modern theory of probability, Pascal also discovered the properties of the cycloid and contributed to the advance of differential calculus. In physics his experiments increased knowledge of atmospheric pressure through barometric measurements and of the equilibrium of fluids (see Pascal's law (1656).

Blaise Pascal Pascal, Blaise (1623-1662), französischer Philosoph, Mathematiker und Physiker, der als einer der großen Denker der westlichen Geistesgeschichte betrachtet wird. Pascal wurde am 19. Juni 1623 in Clermont-Ferrand geboren, und seine Familie ließ sich 1629 in Paris nieder. Von seinem Vater unterwiesen, wurde Pascal bald zu einem mathematischen Wunderkind, und im Alter von 16 Jahren formulierte er einen seiner wichtigen Lehrsätze der projektiven Geometrie, der als Pascalscher Satz bekannt wurde und in seinem Werk Essai pour les coniques (1639, Über die Kegelschnitte) dargelegt wurde. 1642 erfand er die erste mechanische Addiermaschine. 1648 bewies Pascal experimentell, dass die Höhe einer Quecksilbersäule in einem Barometer vom Luftdruck abhängig ist. Diese Entdeckung bestätigte die Hypothese des italienischen Physikers Evangelista Torricelli über die Wirkung des Luftdruckes auf das Gleichgewicht von Flüssigkeiten. Sechs Jahre später formulierte Pascal in Zusammenarbeit mit dem französischen Mathematiker Pierre de Fermat die mathematischen Grundlagen der Wahrscheinlichkeitsrechnung, die große Bedeutung für die Statistik bekommen hat, besonders in den Bereichen Versicherungs- und Bevölkerungstatistik, aber auch wichtige Grundlage für Berechnungen in der modernen theoretischen Physik geworden ist. Zu Pascals weiteren wichtigen, wissenschaftlichen Leistungen zählt das Pascalsche Gesetz oder Prinzip, das besagt, dass in Flüssigkeiten der Druck gleichmäßig in alle Richtungen weitergeleitet wird, ferner seine Untersuchungen zur Infinitesimalrechnung.

Start Geschichte Entwicklungen Napier, John Schickard, Wilhelm Pascal, Blaise Leibniz, G. Wilhelm Babbage, Charles Hollerith, Herman Zuse, Konrad ... Kommentare Blaise Pascal (1623-1662) In Unwissenheit von Schickards "Calculating Clock" erarbeitete Pascal ein Gerät, das seinem Vater, einem Steuereintreiber, eine Arbeitserleichterung bringen sollte. Der Hintergrund für diese Bemühungen war, dass die damalige französische Währung ähnlich komplex war, wie deren englisches Pendant. Pascal baute also eine Maschine, die später nach ihm benannt wurde, welche lediglich die Addition beherrschte. Subtraktion war nur durch rechnerisches Beitun des Anwenders möglich. Pascal war zugleich Philosoph. "[...]Die Vergangenheit und die Gegenwart sind unsere Mittel; allein die Zukunft ist unser Ziel. Deshalb leben wir nie, sondern hoffen auf das Leben, und da wir uns ständig bereit halten, glücklich zu werden, ist es unausbleiblich, dass wir es niemals sind.[...]" So formuliert er den tieferen Sinn für sein Tun, nämlich wollte er durch seine Erfindungen die Zukunft reformieren "[...]Wir halten uns nie an die Gegenwart. Wir rufen uns die Vergangenheit zurück; wir greifen der Zukunft vor, als käme sie zu langsam und als wollten wir ihr Eintreten beschleunigen, oder wir rufen uns die Vergangenheit zurück, als wollten wir sie festhalten, da sie zu schnell vorübereilte, wir sind so unklug, dass wir in Zeiten umherirren [...]" Diese Aussage macht deutlich dass Pascal sein Tun und das Tun seiner Kollegen durchaus kritisch betrachten konnte.
