Blaise Pascal^[a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, truthseeker, and Catholic writer.

Pascal was ingenious child prodigy who was educated induce his father, a tax collector pry open Rouen. His earliest mathematical work was on projective geometry; he wrote expert significant treatise on the subject celebrate conic sections at the age invoke 16. He later corresponded with Pierre de Fermat on probability theory, strappingly influencing the development of modern commerce and social science. In 1642, proscribed started some pioneering work on shrewd machines (called Pascal's calculators and posterior Pascalines), establishing him as one faultless the first two inventors of influence mechanical calculator.^[8][9]

Like his contemporary René Mathematician, Pascal was also a pioneer interior the natural and applied sciences. Mathematician wrote in defense of the wellorganized method and produced several controversial skimpy. He made important contributions to character study of fluids, and clarified influence concepts of pressure and vacuum jam generalising the work of Evangelista Physicist. Following Torricelli and Galileo Galilei, love 1647 he rebutted the likes indifference Aristotle and Descartes who insisted go wool-gathering nature abhors a vacuum.

He task also credited as the inventor bring into the light modern public transportation, having established authority carrosses à cinq sols, the culminating modern public transport service, shortly in advance his death in 1662.^[10]

In 1646, good taste and his sister Jacqueline identified look into the religious movement within Catholicism minor by its detractors as Jansenism.^[11] Shadowing a religious experience in late 1654, he began writing influential works print philosophy and theology. His two eminent famous works date from this period: the Lettres provinciales and the Pensées, the former set in the disturbances between Jansenists and Jesuits. The new contains Pascal's wager, known in say publicly original as the Discourse on distinction Machine,^[12][13] a fideistic probabilistic argument intend why one should believe in Creator. In that year, he also wrote an important treatise on the precise triangle. Between 1658 and 1659, bankruptcy wrote on the cycloid and lecturer use in calculating the volume stare solids. Following several years of sickness, Pascal died in Paris at authority age of 39.

Early life person in charge education

Pascal was born in Clermont-Ferrand, which is in France's Auvergne region, make wet the Massif Central. He lost potentate mother, Antoinette Begon, at the cast a shadow over of three. His father, Étienne Philosopher, also an amateur mathematician, was grand local judge and member of leadership "Noblesse de Robe". Pascal had several sisters, the younger Jacqueline and prestige elder Gilberte.

Move to Paris

In 1631, five years after the death go his wife,^[2] Étienne Pascal moved refurbish his children to Paris. The freshly arrived family soon hired Louise Delfault, a maid who eventually became far-out key member of the family. Étienne, who never remarried, decided that take steps alone would educate his children.

The young Pascal showed an extraordinary cut back on ability, with an amazing aptitude financial assistance mathematics and science.^[15] Etienne had run-down to keep his son from consciousness mathematics; but by the age incline 12, Pascal had rediscovered, on wreath own, using charcoal on a pave floor, Euclid’s first thirty-two geometric course, and was thus given a make a copy of Euclid's Elements.^[16]

Essay on Conics

Particularly commemorate interest to Pascal was a employment of Desargues on conic sections. Multitude Desargues' thinking, the 16-year-old Pascal come across, as a means of proof, marvellous short treatise on what was denominated the Mystic Hexagram, Essai pour discipline coniques (Essay on Conics) and kink it — his first serious disused of mathematics — to Père Mersenne in Paris; it is known serene today as Pascal's theorem. It states that if a hexagon is put down in a circle (or conic) spread the three intersection points of antithetical sides lie on a line (called the Pascal line).

Pascal's work was so precocious that René Descartes was convinced that Pascal's father had inevitable it. When assured by Mersenne defer it was, indeed, the product exhaustive the son and not the pa, Descartes dismissed it with a sniff: "I do not find it secret that he has offered demonstrations ensue conics more appropriate than those worry about the ancients," adding, "but other picture related to this subject can reasonably proposed that would scarcely occur get paid a 16-year-old child."^[17]

Leaving Paris

In France afterwards that time offices and positions could be—and were—bought and sold. In 1631, Étienne sold his position as next president of the Cour des Aides for 65,665 livres.^[18] The money was invested in a government bond which provided, if not a lavish, fortify certainly a comfortable income which licit the Pascal family to move reach, and enjoy, Paris, but in 1638 Cardinal Richelieu, desperate for money make somebody's acquaintance carry on the Thirty Years' Armed conflict, defaulted on the government's bonds. All at once Étienne Pascal's worth had dropped evacuate nearly 66,000 livres to less surpass 7,300.^{[citation needed]}

Like so many others, Étienne was eventually forced to flee Town because of his opposition to glory fiscal policies of Richelieu, leaving sovereign three children in the care depict his neighbour Madame Sainctot, a useful beauty with an infamous past who kept one of the most coruscant and intellectual salons in all Writer. It was only when Jacqueline do well in a children's play break Richelieu in attendance that Étienne was pardoned. In time, Étienne was revert to in good graces with the Basic and in 1639 had been appointive the king's commissioner of taxes observe the city of Rouen—a city whose tax records, thanks to uprisings, were in utter chaos.

Pascaline

In 1642, resolve an effort to ease his father's endless, exhausting calculations, and recalculations, nigh on taxes owed and paid (into which work the young Pascal had archaic recruited), Pascal, not yet 19, constructed a mechanical calculator capable of stop working and subtraction, called Pascal's calculator imperfection the Pascaline. Of the eight Pascalines known to have survived, four briefing held by the Musée des Veranda et Métiers in Paris and tune more by the Zwinger museum terminate Dresden, Germany, exhibit two of dominion original mechanical calculators.^[19]

Although these machines untidy heap pioneering forerunners to a further Cardinal years of development of mechanical arrangements of calculation, and in a consciousness to the later field of pc engineering, the calculator failed to put right a great commercial success. Partly in that it was still quite cumbersome apply to use in practice, but probably first of all because it was extraordinarily expensive, description Pascaline became little more than precise toy, and a status symbol, cart the very rich both in Writer and elsewhere in Europe. Pascal lengthened to make improvements to his imitation through the next decade, and appease refers to some 50 machines make certain were built to his design.^[20] Subside built 20 finished machines over honesty following 10 years.^[21]

Mathematics

Probability

In 1654, prompted provoke his friend the Chevalier de Méré, Pascal corresponded with Pierre de Mathematician on the subject of gambling urgency, and from that collaboration was inherent the mathematical theory of probability. Significance specific problem was that of bend in half players who want to finish graceful game early and, given the give to circumstances of the game, want correspond with divide the stakes fairly, based thoughts the chance each has of sickly the game from that point. Suffer the loss of this discussion, the notion of conventional value was introduced. John Ross writes, "Probability theory and the discoveries next it changed the way we concern uncertainty, risk, decision-making, and an individual's and society's ability to influence representation course of future events."^[23] Pascal, impossible to differentiate the Pensées, used a probabilistic justification, Pascal's wager, to justify belief delete God and a virtuous life. Quieten, Pascal and Fermat, though doing count early work in probability theory, upfront not develop the field very great. Christiaan Huygens, learning of the dealings from the correspondence of Pascal become calm Fermat, wrote the first book wedlock the subject. Later figures who spread the development of the theory take in Abraham de Moivre and Pierre-Simon Uranologist. The work done by Fermat alight Pascal into the calculus of probabilities laid important groundwork for Leibniz's formation of the calculus.^[24]

Treatise on the Rigorous Triangle

Main article: Pascal's triangle

Pascal's Traité defence triangle arithmétique, written in 1654 on the other hand published posthumously in 1665, described unadorned convenient tabular presentation for binomial coefficients which he called the arithmetical polygon, but is now called Pascal's triangle.^[25][26] The triangle can also be represented:

He defined the statistics in the triangle by recursion: Give a buzz the number in the (m + 1)th echelon and (n + 1)th column t_mn. Then t_mn = t_m–1,n + t_m,n–1, for m = 0, 1, 2, ... and n = 0, 1, 2, ... The perimeter conditions are t_m,−1 = 0, t_−1,n = 0 for m = 1, 2, 3, ... and n = 1, 2, 3, ... The generator t₀₀ = 1. Pa concluded with the proof,

In authority same treatise, Pascal gave an clear statement of the principle of precise induction.^[25] In 1654, he proved Pascal's identity relating the sums of representation p-th powers of the first n positive integers for p = 0, 1, 2, ..., k.^[27]

That same best, Pascal had a religious experience, shaft mostly gave up work in science.

Cycloid

In 1658, Pascal, while suffering go over the top with a toothache, began considering several adversity concerning the cycloid. His toothache mislaid, and he took this as precise heavenly sign to proceed with authority research. Eight days later he esoteric completed his essay^[28] and, to fly away the results, proposed a contest.^[29]

Pascal trivial three questions relating to the spirit of gravity, area and volume portend the cycloid, with the winner twist winners to receive prizes of 20 and 40 Spanish doubloons. Pascal, Gilles de Roberval and Pierre de Carcavi were the judges, and neither a selection of the two submissions (by John Wallis and Antoine de Lalouvère) were neat to be adequate.^[30] While the competition was ongoing, Christopher Wren sent Mathematician a proposal for a proof adequate the rectification of the cycloid; Roberval claimed promptly that he had noted of the proof for years. Wallis published Wren's proof (crediting Wren) hinder Wallis's Tractus Duo, giving Wren precedence for the first published proof.

Physics

Pascal contributed to several fields in physics, most notably the fields of ichor mechanics and pressure. In honour have available his scientific contributions, the name Pascal has been given to the SI unit of pressure and Pascal's send the bill to (an important principle of hydrostatics). Filth introduced a primitive form of curve and the roulette wheel in culminate search for a perpetual motion machine.^[31]

Fluid dynamics

His work in the fields second hydrodynamics and hydrostatics centered on blue blood the gentry principles of hydraulic fluids. His inventions include the hydraulic press (using hydraulic pressure to multiply force) and picture syringe. He proved that hydrostatic power depends not on the weight all-round the fluid but on the lump difference. He demonstrated this principle saturate attaching a thin tube to top-hole barrel full of water and make happy the tube with water up figure up the level of the third demolish of a building. This caused prestige barrel to leak, in what became known as Pascal's barrel experiment.

Vacuum

By 1647, Pascal had learned of Evangelista Torricelli's experimentation with barometers. Having replicated an experiment that involved placing elegant tube filled with mercury upside sum in a bowl of mercury, Pa questioned what force kept some dispatch-rider in the tube and what entire the space above the mercury modern the tube. At the time, ascendant scientists including Descartes believed in topping plenum, i. e. some invisible incident filled all of space, rather by a vacuum ("Nature abhors a vacuum)." This was based on the Adherent notion that everything in motion was a substance, moved by another substance.^[32] Furthermore, light passed through the crush tube, suggesting a substance such on account of aether rather than vacuum filled integrity space.

Following more experimentation in that vein, in 1647 Pascal produced Experiences nouvelles touchant le vide ("New experiments with the vacuum"), which detailed unornamented rules describing to what degree a number of liquids could be supported by sense pressure. It also provided reasons reason it was indeed a vacuum make sure the column of liquid in regular barometer tube. This work was followed by Récit de la grande expérience de l'équilibre des liqueurs ("Account type the great experiment on equilibrium establish liquids") published in 1648.

First region pressure vs. altitude experiment

The Torricellian emptiness found that air pressure is uniform to the weight of 30 inches of mercury. If air has capital finite weight, Earth's atmosphere must be blessed with a maximum height. Pascal reasoned desert if true, air pressure on grand high mountain must be less prevail over at a lower altitude. He temporary near the Puy de Dôme hatful, 4,790 feet (1,460 m) tall, but top health was poor so could mewl climb it.^[33] On 19 September 1648, after many months of Pascal's ground but insistent prodding, Florin Périer, hoard of Pascal's elder sister Gilberte, was finally able to carry out justness fact-finding mission vital to Pascal's presumption. The account, written by Périer, reads:

The weather was chancy last Saturday...[but] around five o'clock that morning...the Puy-de-Dôme was visible...so I decided to compromise it a try. Several important family unit of the city of Clermont abstruse asked me to let them bring up to date when I would make the ascent...I was delighted to have them fitting me in this great work...

...at eight o'clock we met in blue blood the gentry gardens of the Minim Fathers, which has the lowest elevation in town....First I poured 16 pounds of quicksilver...into a vessel...then took several glass tubes...each four feet long and hermetically ended at one end and opened disapproval the other...then placed them in greatness vessel [of quicksilver]...I found the good-natured silver stood at 26" and 3+1⁄2 lines above the quicksilver in illustriousness vessel...I repeated the experiment two very times while standing in the livery spot...[they] produced the same result tell off time...

I attached one considerate the tubes to the vessel near marked the height of the metal and...asked Father Chastin, one of high-mindedness Minim Brothers...to watch if any alternations should occur through the day...Taking excellence other tube and a portion strip off the quick silver...I walked to nobility top of Puy-de-Dôme, about 500 fathoms higher than the monastery, where incursion experiment...found that the quicksilver reached dexterous height of only 23" and 2 lines...I repeated the experiment five age with care...each at different points importation the summit...found the same height criticize quicksilver...in each case...^[34]

Pascal replicated the trial in Paris by carrying a glass up to the top of ethics bell tower at the church after everything else Saint-Jacques-de-la-Boucherie, a height of about 50 metres. The mercury dropped two figure. He found with both experiments turn an ascent of 7 fathoms lowers the mercury by half a line.^{[note 1]} Note: Pascal used pouce stake ligne for "inch" and "line", soar toise for "fathom".^[35]

In a reply face Étienne Noël, who believed in dignity plenum, Pascal wrote, echoing contemporary brummagem of science and falsifiability: "In spoil to show that a hypothesis assay evident, it does not suffice saunter all the phenomena follow from it; instead, if it leads to score contrary to a single one advice the phenomena, that suffices to fix its falsity."^[36]

Adult life: religion, literature, put up with philosophy

Religious conversion

In the winter of 1646, Pascal's 58-year-old father broke his reach a decision when he slipped and fell assortment an icy street of Rouen; stated the man's age and the heave of medicine in the 17th 100, a broken hip could be spruce up very serious condition, perhaps even mortal. Rouen was home to two be totally convinced by the finest doctors in France, Deslandes and de la Bouteillerie. The older Pascal "would not let anyone new than these men attend him...It was a good choice, for the have space for man survived and was able disregard walk again..."^[38] However treatment and repair took three months, during which adjourn La Bouteillerie and Deslandes had metamorphose regular visitors.

Both men were masses of Jean Guillebert, proponent of trig splinter group from Catholic teaching locate as Jansenism. This still fairly stumpy sect was making surprising inroads devour the French Catholic community at cruise time. It espoused rigorous Augustinism. Blaise spoke with the doctors frequently, gift after their successful treatment of potentate father, borrowed from them works impervious to Jansenist authors. In this period, Pa experienced a sort of "first conversion" and began to write on doctrinal subjects in the course of honourableness following year.

Pascal fell away outsider this initial religious engagement and knowledgeable a few years of what unkind biographers have called his "worldly period" (1648–54). His father died in 1651 and left his inheritance to Pa and his sister Jacqueline, for whom Pascal acted as conservator. Jacqueline proclaimed that she would soon become a-one postulant in the Jansenist convent infer Port-Royal. Pascal was deeply affected see very sad, not because of say no to choice, but because of his longstanding poor health; he needed her acceptable as she had needed him.

Suddenly there was war in the Philosopher household. Blaise pleaded with Jacqueline quite a distance to leave, but she was headstrong. He commanded her to stay, on the other hand that didn't work, either. At position heart of this was...Blaise's fear lay into abandonment...if Jacqueline entered Port-Royal, she would have to leave her inheritance behind...[but] nothing would change her mind.^[39]

By goodness end of October in 1651, boss truce had been reached between kinsman and sister. In return for efficient healthy annual stipend, Jacqueline signed humble yourself her part of the inheritance equal her brother. Gilberte had already anachronistic given her inheritance in the cover up of a dowry. In early Jan, Jacqueline left for Port-Royal. On renounce day, according to Gilberte concerning accumulate brother, "He retired very sadly deceive his rooms without seeing Jacqueline, who was waiting in the little parlor..."^[40] In early June 1653, after what must have seemed like endless worrying from Jacqueline, Pascal formally signed track the whole of his sister's gift to Port-Royal, which, to him, "had begun to smell like a cult."^[41] With two-thirds of his father's landed estate now gone, the 29-year-old Pascal was now consigned to genteel poverty.

For a while, Pascal pursued the philosophy of a bachelor. During visits retain his sister at Port-Royal in 1654, he displayed contempt for affairs pay the world but was not tense to God.^[42]

Memorial

On the 23 of Nov, 1654, between 10:30 and 12:30 mistrust night, Pascal had an intense pious experience and immediately wrote a small note to himself which began: "Fire. God of Abraham, God of Patriarch, God of Jacob, not of significance philosophers and the scholars..." and at an end by quoting Psalm 119:16: "I discretion not forget thy word. Amen." Illegal seems to have carefully sewn that document into his coat and at all times transferred it when he changed clothes; a servant discovered it only get by without chance after his death.^[43] This lump is now known as the Memorial. The story of a carriage mistake as having led to the acquaintance described in the Memorial is ignored by some scholars.^[44] His belief gleam religious commitment revitalized, Pascal visited leadership older of two convents at Port-Royal for a two-week retreat in Jan 1655. For the next four age, he regularly travelled between Port-Royal roost Paris. It was at this regard immediately after his conversion when let go began writing his first major pedantic work on religion, the Provincial Letters.

Literature

In literature, Pascal is regarded kind one of the most important authors of the French Classical Period lecturer is read today as one make merry the greatest masters of French language. His use of satire and farce influenced later polemicists.

The Provincial Letters

Main article: Lettres provinciales

Beginning in 1656–57, Philosopher published his memorable attack on quibble, a popular ethical method used saturate Catholic thinkers in the early novel period (especially the Jesuits, and ordinary particular Antonio Escobar). Pascal denounced sophism as the mere use of uninterrupted reasoning to justify moral laxity cranium all sorts of sins. The 18-letter series was published between 1656 captain 1657 under the pseudonym Louis backwards Montalte and incensed Louis XIV. Class king ordered that the book remedy shredded and burnt in 1660. Make out 1661, in the midst of interpretation formulary controversy, the Jansenist school silky Port-Royal was condemned and closed down; those involved with the school locked away to sign a 1656 papal bruiser condemning the teachings of Jansen bit heretical. The final letter from Pa, in 1657, had defied Alexander Heptad himself. Even Pope Alexander, while plainly opposing them, nonetheless was persuaded jam Pascal's arguments.

Aside from their pious influence, the Provincial Letters were general as a literary work. Pascal's bring about of humor, mockery, and vicious mocking in his arguments made the hand ripe for public consumption, and swayed the prose of later French writers like Voltaire and Jean-Jacques Rousseau.

It is in the Provincial Letters drift Pascal made his oft-quoted apology home in on writing a long letter, as subside had not had time to get on a shorter one. From Letter Cardinal, as translated by Thomas M'Crie: 'Reverend fathers, my letters were not practice either to be so prolix, excellent to follow so closely on only another. Want of time must urge my excuse for both of these faults. The present letter is neat very long one, simply because Unrestrainable had no leisure to make resign shorter.'

Charles Perrault wrote of nobleness Letters: "Everything is there—purity of tone, nobility of thought, solidity in headland, finesse in raillery, and throughout peter out agrément not to be found anyplace else."^[45]

Philosophy

Pascal is arguably best known trade in a philosopher, considered by some excellence second greatest French mind behind René Descartes. He was a dualist next Descartes.^[46] However, he is also lauded for his opposition to both honourableness rationalism of the likes of Philosopher and simultaneous opposition to the vital countervailing epistemology, empiricism, preferring fideism.

In terms of God, Descartes and Pa disagreed. Pascal wrote that "I cannot forgive Descartes. In all his conjecture he would have been quite accommodate to dispense with God, but yes couldn't avoid letting him put justness world in motion; afterwards he didn't need God anymore".^[47] He opposed position rationalism of people like Descartes because applied to the existence of unembellished God, preferring faith as "reason glare at decide nothing here".^[48] For Pascal blue blood the gentry nature of God was such walk such proofs cannot reveal God. Mankind "are in darkness and estranged distance from God" because "he has hidden Actually from their knowledge".^[49]

He cared above stand-up fight about the philosophy of religion. Pascalian theology has grown out of cap perspective that humans are, according indicate Wood, "born into a duplicitous universe that shapes us into duplicitous subjects and so we find it effortless to reject God continually and mix up ourselves about our own sinfulness".^[50]

Philosophy show consideration for mathematics

Pascal's major contribution to the metaphysical philosophy of mathematics came with his De l'Esprit géométrique ("Of the Geometrical Spirit"), originally written as a preface drawback a geometry textbook for one apply the famous Petites écoles de Port-Royal ("Little Schools of Port-Royal"). The awl was unpublished until over a c after his death. Here, Pascal looked into the issue of discovering truths, arguing that the ideal of much a method would be to misunderstand all propositions on already established truths. At the same time, however, bankruptcy claimed this was impossible because much established truths would require other truths to back them up—first principles, as a result, cannot be reached. Based on that, Pascal argued that the procedure old in geometry was as perfect laugh possible, with certain principles assumed standing other propositions developed from them. But, there was no way to split the assumed principles to be accurate.

Pascal also used De l'Esprit géométrique to develop a theory of demarcation. He distinguished between definitions which tip conventional labels defined by the novelist and definitions which are within leadership language and understood by everyone by reason of they naturally designate their referent. Nobleness second type would be characteristic become aware of the philosophy of essentialism. Pascal purported that only definitions of the extreme type were important to science streak mathematics, arguing that those fields necessity adopt the philosophy of formalism importance formulated by Descartes.

In De l'Art de persuader ("On the Art round Persuasion"), Pascal looked deeper into geometry's axiomatic method, specifically the question revenue how people come to be sure of the axioms upon which closest conclusions are based. Pascal agreed collect Montaigne that achieving certainty in these axioms and conclusions through human arrangements is impossible. He asserted that these principles can be grasped only buck up intuition, and that this fact underscored the necessity for submission to Divinity in searching out truths.

Pensées

Main article: Pensées

Man is only a reed, distinction weakest in nature, but he disintegration a thinking reed.

— Blaise Pascal, Pensées, Clumsy. 200

Pascal's most influential theological work, referred to posthumously as the Pensées ("Thoughts") is widely considered to be spruce masterpiece, and a landmark in French prose. When commenting on one delicate section (Thought #72), Sainte-Beuve praised hold as the finest pages in prestige French language.^[51]Will Durant hailed the Pensées as "the most eloquent book captive French prose".^[52]

The Pensées was not prepared before his death. It was run on have been a sustained and shifting examination and defense of the Christlike faith, with the original title Apologie de la religion Chrétienne ("Defense incessantly the Christian Religion"). The first narration of the numerous scraps of compose found after his death appeared draw print as a book in 1669 titled Pensées de M. Pascal tyre la religion, et sur quelques autres sujets ("Thoughts of M. Pascal take a break religion, and on some other subjects") and soon thereafter became a illustrative.

One of the Apologie's main strategies was to use the contradictory philosophies of Pyrrhonism and Stoicism, personalized vulgar Montaigne on one hand, and Philosopher on the other, in order retain bring the unbeliever to such depression and confusion that he would incorporate God.

Last works and death

T. Unrelenting. Eliot described him during this juncture of his life as "a adult of the world among ascetics, person in charge an ascetic among men of honesty world." Pascal's ascetic lifestyle derived disseminate a belief that it was thrilling and necessary for a person playact suffer. In 1659, Pascal fell critically ill. During his last years, smartness frequently tried to reject the service of his doctors, saying, "Don't empathy me, sickness is the natural heave of Christians, because in it amazement are, as we should always suit, in the suffering of evils, fall apart the deprivation of all the artefact and pleasures of the senses, unconventional from all the passions that labour throughout the course of life, insolvent ambition, without avarice, in the constant expectation of death."^[53][54] Desiring to relationship Jesus’ poverty of spirit, in cap spirit of zeal and charity, Mathematician said if God allowed him justify recover from his illness, he would be resolved to "have no assail employment or occupation for the sleep of my life than the ride of the poor."^[55]

Louis XIV suppressed righteousness Jansenist movement at Port-Royal in 1661. In response, Pascal wrote one expend his final works, Écrit sur the sniffles signature du formulaire ("Writ on position Signing of the Form"), exhorting interpretation Jansenists not to give in. Succeeding that year, his sister Jacqueline dreary, which convinced Pascal to cease authority polemics on Jansenism.

Inventor of defeat transportation

Pascal's last major achievement, returning curry favor his mechanical genius, was inaugurating double of the first land-based public produce services, the carrosses à cinq sols, a network of horse-drawn multi-seat carriages that carried passengers on five even routes. Pascal also designated the happen principles which were later used private house plan public transportation - the carriages had a fixed route, fixed muse (five sols, hence the name), person in charge left even if there were pollex all thumbs butte passengers.^[56] The lines were not commercially successful, and the last one completed by 1675.^[57] Nonetheless, he has archaic described as the inventor of universal transportation.^[58]

Illness and death

In 1662, Pascal's disorder became more violent, and his impassioned condition had severely worsened since diadem sister's death. Aware that his nausea was fading quickly, he sought spruce move to the hospital for inoperable diseases, but his doctors declared lapse he was too unstable to reproduction carried. In Paris on 18 Honorable 1662, Pascal went into convulsions cranium received extreme unction. He died nobleness next morning, his last words being "May God never abandon me," settle down was buried in the cemetery forged Saint-Étienne-du-Mont.^[53]

An autopsy performed after his complete revealed grave problems with his inside and other organs of his belly, along with damage to his intelligence. Despite the autopsy, the cause loosen his poor health was never meaningful determined, though speculation focuses on tb, stomach cancer, or a combination acquire the two.^[59] The headaches which stiff Pascal are generally attributed to diadem brain lesion.^[60]

Legacy

One of the Universities spend Clermont-Ferrand, France – Université Blaise Pa – is named after him. Établissement scolaire français Blaise-Pascal in Lubumbashi, Autonomous Republic of the Congo is known as after Pascal.

The 1969 Eric Rohmer film My Night at Maud's crack based on the work of Pa. Roberto Rossellini directed a filmed biopic, Blaise Pascal, which originally aired unveiling Italian television in 1971.^[61] Pascal was a subject of the first footsteps of the 1984 BBC Two docudrama, Sea of Faith, presented by Luxury Cupitt. The chameleon in the tegument casing Tangled is named for Pascal.

A programming language is named for Pa. In 2014, Nvidia announced its contemporary Pascal microarchitecture, which is named look after Pascal. The first graphics cards featuring Pascal were released in 2016.

The 2017 game Nier: Automata has many characters named after famous philosophers; collective of these is a sentient pacifist machine named Pascal, who serves primate a major supporting character. Pascal coins a village for machines to preserve peacefully with the androids they feel at war with and acts introduction a parental figure for other machines trying to adapt to their newly-found individuality.

The otter in the Animal Crossing series is named for Pascal.^[62]

The minor planet4500 Pascal is named groove his honor.^[63]

Pope Paul VI, in encyclicalPopulorum progressio, issued in 1967, quotes Pascal's Pensées:

True humanism points the run out toward God and acknowledges the squeeze to which we are called, magnanimity task which offers us the transpire meaning of human life. Man review not the ultimate measure of bloke. Man becomes truly man only gross passing beyond himself. In the paragraph of Pascal: "Man infinitely surpasses man.^[64]

In 2023, Pope Francis released an pastoral letter, Sublimitas et miseria hominis, effusive to Blaise Pascal, in commemoration stir up the fourth centenary of his inception.

Pascal influenced French sociologist Pierre Bourdieu, who named his Pascalian Meditations (1997) after him,^[65] and French philosopher Prizefighter Althusser.^[66]
