Biography
Early rocks
Jean Baptiste Joseph Four'ie was 12 of 15 children in Kravets's homeland (nine were from another whore's father). My father, Joseph Fourie, came from the homeland of Kramar from the small town of Loryan. In the 16th-17th century, P'ère Fourie, the great-uncle of Jean Fourie, was a prominent figure in Counter Reformation in the area. His mother, Edmie, died in 1777, when Fourie was nine years old, and his father died at the same time. After other events, Fur'e became an orphan at the age of eight.
In his first school, as a church musician, Fourie showed success in the learned French and Latin. At the age of 12 years for the marriage of Bishop Auxerre, Four'e was in charge of the military school at the Benedictine monastery. Until the age of 13, Joseph became interested in mathematics, and at the age of 14, he mastered the six-volume “Course of Mathematics” by Bezout. At this very hour, we began to collect unburnt candles from the existing schools, so that our mothers could occupy themselves at night. In 1782-1783, Fur'e rejected the most important prizes from rhetoric, mathematics, mechanics and science. The onset of illness, perhaps, was explained by the intense activities.
In the 17th River, he started his military career and wanted to become an artilleryman or military engineer. Unrespectful of the support of school teachers and inspectors, Fur'e, having rejected Vidmova, is associated with his unknown adventures. In 1787, Four's family entered the Benedictine Abbey of St. Benoit-sur-Loire, intending to take rank. At the same time, the young man doubted his choice, submitted documents to Montucla Paris, lost the abbey in 1789 and went to the capital. In Paris at the Royal Academy of Sciences, Fourie presented a paper on the numerically superior level of any level.
At the hour of the Great Revolution
The revolution came earlier, no matter whether you are a Chen, a military man or a mathematician. The revolutionary decree of 1789 fatefully confiscated the religious houses, and immediately the churches and black orders were confiscated. Four turned back to Auxerre and began studying mathematics, rhetoric, history and philosophy at the school, which he himself had completed. The commissar, who went to school in 1792, wanted to take over the liberal atmosphere and, in the face of discontent, to take up the Latin language with a small amount, who, in spite of their fathers, decided to take over mathematics
Until the year 1793, Fourie did not engage in politics, regardless of the fact that in Auxerre the military provincial branch of the Jacobist party was growing. In 1793, a heated debate arose in Auxerre over the principles of bringing the people of the region to a powerful Convention. Fourie spoke at this debate and presented a plan that would be the solution to the attempts. In the birch of 1793, Four's fate, having rejected the proposition, entered before the Comite de Surveillance, having accepted it. In the spring of the same fate, a committee that took up the rights of mandrivniks, becoming part of the revolutionary terror and calls for the arrest of the thieves of tyranny or federalism and the enemies of freedom. Fury, who does not deserve to take his fate, submitted a written request to leave the committee, which was taken away
On the right, the committee of wines has been reduced to the department of Loiret. In the meantime, Orleans has become a participant in a local conflict, facing the death of the heads of several local families, if the representative of the Convention made anonymous arrests and decided to vikorize the over-the-top guillotine. As a result of the 29th of June 1793, the renaissance of the rebels was unable to be repealed and Fouriet returned to Auxerre in fear, continuing to serve in the local branch and attend school. Moreover, in the early 1794 he became president of the revolutionary committee in Oserie. After this, the Fury went straight to Paris in contact with Robespere, but was not successful, leaving 4 lines, immediately after turning to Auxerre, he was arrested. Vin has already checked for the guillotine, if as a result of the coup of the 9th Thermidor Robesp'er was arrested and expelled, after which Fur'e was released.
On June 30, 1794, by decree of the Convention near Paris, a Normal School was organized, and 1,500 students began to work in this small republic, who became school teachers. Students were nominated from various districts, Croreme, Auxerre, by nominating their candidate at the time that Four's seat was in office, from the district of Saint-Florentine and entering school after the Confirmation from Auxerre. The school has contributed such famous works as Lagrange, Laplace, Monge, Bertoli. Activities began on the 20th of June 1795, and in the spring of 1795 the school was founded.
At the same time, Four'ie's opponents wrote a letter to the Normal School, firmly insisting that it was impossible to prepare teachers for the children of these candidates, who were also supporters of Robesp'iere, Four'e's own sacristan. In 1795, fate came to Auxerre with two orders: on the 12th of May - to neutralize the participants in the terror, including Fourie, on the 30th of May - those who were tempted to take the war. At that time, Fourie took up a position at the Polytechnic School, as I call it at that time. You will be able to carry out the operation by checking the position and writing a letter to the municipality of Auxerre, as well as 7 copies of collections and referrals to contact. In connection with the war, having written faceless sheets on his protection, hardening zokrem, so that under Robesp'ier, he was imprisoned in the connection and the coup of the 9th Thermidor, in the end of his life and freedom. In 1795, for some unknown reason, Fury was released. This must be linked to the political climate that has changed in the region, or with the possible intercession of Lagrange and Monge.
Egyptian campaign

Bust of Fourieux in Grenoble
Fouries returned to France in 1801 and became a professor at the Polytechnic School. Prote, Napoleon assigned his post of prefect to the department of Isère, and Fourie was convinced of the proposal and defeated at Grenoble. Four's main achievements at his post were the maintenance of drainage at Bourgoin, as well as the construction of a new road that connected Grenoble with Turin. At the same hour, Fur was working on the collection en. with original text).
In 1809, Fury rejected the title of Baron from Napoleon and awarded the Order of the Legion of Honor.
In 1812, Napoleon suffered defeats and was sent to Elba. On our way to pass through Grenoble, Prote Fourie sent a note that the place might not be safe. If Napoleon had lost Elba and destroyed his army through Grenoble, Fourie hastily lost the place, causing Napoleon's dissatisfaction. Fur would later secure the favor of the Emperor, who recognized him as Prefect of Roni. However, Fur’s never lost his posad. On the 10th of June 1815, Napoleon awarded Fourie a pension of 6 thousand francs, but Fourie did not take it away every time, the fragments of 1 lime Napoleon recognized the defeats. After this, Fourie returned to Paris, where he worked as director of the Bureau of Statistics for an hour, and in 1817 he became a member of the Academy.
Pozni rocks
In 1826 he also became a member of the Académie Française and the Académie de Médecine.
In 1804, while in Grenoble, Fourie began work on the theory of the expansion of heat in solids. Until 1807, he prepared a sermon “On the expansion of heat in solids,” which he presented to 21 people at the same time in Paris. The testimony gave off an even superb assessment. Lagrange and Laplace could not come to terms with the fact that Four's expansion of the functions of trigonometric series, hence called his names. Further clarification, the Furs also could not have stolen their point of view. In addition, Bio spoke out against the formulation of Fur'e equal to the spread of heat. Fury in his work did not agree to a similar work by Bio, published by him in 1804. From Bio there was Laplace and later Poisson. Later, in 1812, the analytical theory of thermal conductivity, presented by Fourie, won the Grand Prize of the Academy. However, the greatest mastery was achieved only in the era of Hilbert.
In 1818, Fur's family began to work on the minds of the people using the method of numerical equations developed by Newton. Similar results were already obtained in 1768 by Murail. The results of this work were visible only 1831 years after the death of the deceased.
In 1817, Four's son was elected a member of the Academy of Sciences, resisting the pressure of the Bourbons. The first attempt in 1816 did not succumb to fate, King Louis XVIII succumbed to the crime. In 1822, after the death of d'Alembert, he was appointed secretary of the mathematical section. Almost immediately after this, his work “The Analytical Theory of Heat” (“Théorie analytique de la chaleur”) was published, which Lord Kelvin called “The Great Mathematical Poem.” Nowadays, Fury is engaged in the publication of his work in both pure and applied mathematics. His theory of heat was still crying out for supers, Bio attributing the feathers to his diet, and Poisson criticizing Fouret's mathematical approach and developing an alternative theory.

Having started at the Normal School, already being an accomplished speaker, Fourie assessed his teachers and their manner of delivering lectures. He noted the chaotic approach to Lagrange's report, as well as his compromise in propositions, as Four'e respected his Italian roots, calling him an extraordinary person. He called Laplace's lectures precise, but rather quick and of little value. Monge's lectures, behind Fourie's words, were careful and reasonable, delivered in a booming voice. I thought that Berthollet’s lectures on chemistry could understand only those who already knew the subject, who would speak forcefully, repeat themselves and repeat themselves too much.
Being engaged in the selection of students at the Polytechnic School, Four'e appreciated that more than diligence is an important talent. One of Fourie's students was Poisson, who replaced him in school during the Egyptian campaign, and then became his opponent of the analytical theory of heat proposed by Fourie.
Political look
Initially, Fur'e was in the position of an inveterate Jacobist, and later became a dead liberal.
It is important to note that Fourth began to promote the ideas of zeal long before joining the committee, as evidenced by a sheet of Fourth himself, writings from as early as 1795, and joining the committee itself is associated with the goal of seizing the Republic. against aggression side of Belgium and the uprising in Vendee.
Jean Baptiste Joseph Fourie.
(21.3.1768-16.5.1830)
French mathematician, member of the Paris Academy of Sciences (1817). Having graduated from military school in Auxerre, he was born and worked there as a bookkeeper. In 1796-98 he contributed to the Polytechnic School.
Fur's first steps lie before algebra. Already in lectures 1796 r. he introduced a theorem about the number of active roots of the level of algebra that lie between these boundaries (published in 1820), called his name; Above all, the number of active roots of the algebraic equation has been distilled into 1. . In 1818 Fur'e followed up on the food about the stagnation of the disintegrated I. Newton's method of numerical solution, without knowing about similar results, was adopted in 1768 by the French mathematician J. R. Murail. Fur's work on the numerical methods of unraveling the verses in his “Analysis of the Songs of the verses” dates back to approximately 1831.
Fur's main field was mathematical physics. In 1807 and 1811 he presented to the Parisian Academy of Sciences his first ideas on the theory of expansion of heat in solids, and in 1822 he published his work “Analytical Theory of Heat”, which played a great role in the future history of mathematics. She has developed a differential level of thermal conductivity and developed ideas from earlier studies by D. Bernoulli, breaking down the highest level of thermal conductivity for these and other set boundaries. of their minds, the method is so changeable that it stagnates to low drops (cube, cylinder and others...). This method is based on the discovery of functions by Fourie's trigonometric series, which had been seen earlier, but only became relevant to the important principles of mathematical physics in Fourie's work. The method of semi-changing developments in the practice of Z. Poisson, M.V. Ostrogradsky and other mathematicians of the 19th century. “Analytical theory of heat” became the starting point for the development of the theory of trigonometric series and the development of various hidden problems of mathematical analysis. Four'e's first applications are laid out in trigonometric series by Four'e's functions, which are set on different plots by different analytical viruses. Tim himself made an important contribution from the top of the famous superchka about the concept of functions, in which most mathematicians of the 18th century took part. His attempt to bring to light the possibility of expanding into a trigonometric Four'e series of any sufficient function was not far off, but began a great cycle of investigations devoted to the problem of representation of functions by trigonometric series (P. Dirichle, N.I. Loba Chevsky, B. Riman and in.). These investigations were significantly related to the theory of multiplicity and the theory of the function of an active variable.
Jean Baptiste Joseph Four'ie was 12 of 15 children in Kravets's homeland (nine were from another whore's father). His mother died when Fur was nine years old, and his father died. After other events, Fur'e became an orphan at the age of eight.
In his first school, as a church musician, Fourie showed success in the learned French and Latin. At the age of 12 years for the marriage of Bishop Auxerre, Four'e was in charge of the military school at the Benedictine monastery. Until the age of 13, Joseph became interested in mathematics, and at the age of 14, he mastered Bezout’s six-volume course of mathematics. In 1787, Four's family entered the Benedictine Abbey of St. Benoit-sur-Loire, intending to take rank. At the same time, the young man doubted his choice, submitted documents to Montucla Paris, lost the abbey in 1789 and went to the capital. In Paris, at the Royal Academy of Sciences, Four'e presented a paper on the numerically superior level of any level, and after turning around in 1790, he began to contribute to the military school in Oser, which he himself graduated from.
The revolution came earlier, no matter whether you are a Chen, a military man or a mathematician. 1793 Fourth joined the local revolutionary committee and became involved in politics. He wrote that “with the development of ideas of zeal, it became possible to implement the idea of creating a free order.” At the same time, Fury became dissatisfied with the terror, so he became incensed and decided to leave the committee, but did not dare. While in Orleans, Fury stole one of the revolutionary movements, which caused the arrest of Lipney in 1794. Fury was afraid that he would be wasted on the guillotine, but he was released after Robesp'er's death.
In 1794, Fur's family was admitted to the Parisian Normal School, which began training teachers. The work started at the moment of the oncoming fate. Yogo vikladachami bouli Lagrange, Laplace ta Monge. For their encouragement, Fourie took up a position at a polytechnic school, where he was able to continue his scientific work, as well as taking up his studies. The Orleans Incident was discontinued in 1795 when Fourie was again arrested. The support of his readers and the improvement of the political climate in the region helped him to be released. On Spring 1, 1795, Four turned to work, and two years later he became the chair of the department of analysis and mechanics, replacing Lagrange in this position.
In 1798, Napoleon launched his Egyptian campaign, requesting Fourie, Monge and Malus. At the time of the occupation of Egypt, Fury worked for the French administration, carrying out archaeological excavations, and also engaged in the formation of lighting. He took part in the creation of the Cairo Institute and was one of the 12 members of the mathematical department, next to Monge, Malus and Napoleon himself. In addition, Fury was elected secretary of the institute and lost the entire hour of his stay in Egypt.
In 1809, Fury rejected the title of Baron from Napoleon and awarded the Order of the Legion of Honor.
In 1812, Napoleon recognized his defeats and went to the Elba. On our way to pass through Grenoble, Prote Fourie sent a note that the place might not be safe. If Napoleon had lost Elba and destroyed his army through Grenoble, Fourie hastily lost the place, causing Napoleon's dissatisfaction. Fur would later secure the favor of the emperor, who recognized him as prefect of Roni. However, Fur’s never lost his posad. On the 10th of June 1815, Napoleon awarded Fourie a pension of 6 thousand francs, but Fourie did not take it away every time, the fragments of 1 lime Napoleon recognized the defeats. After this, Fourth returned to Paris, becoming director of the Bureau of Statistics, and in 1817 becoming a member of the Academy.
Together with Egyptologists, Fur'ie also became a member of the Académie Française and Académie de Médecine in 1826.

Back in 1789, in Paris at the Royal Academy of Sciences, Fourie presented a paper on the numerical superiority of any level. In his lectures in 1796, he introduced a theorem about the number of active roots of the algebra that lies between these cordons, called the year of his name. This robot found its logical conclusion in the robots of Sturm in 1829 and Koshy.
In 1804, while in Grenoble, Fourier developed a theory of the expansion of heat in solids. Until 1807, he prepared a sermon “On the expansion of heat in solids,” which he presented to 21 people at the same time in Paris. The testimony gave off an even superb assessment. Lagrange and Laplace could not come to terms with the fact that Four's expansion of the functions of trigonometric series, hence called his names. Further clarification, the Furs also could not have stolen their point of view. In addition, Biot spoke against the formulation of Fur's equalization of heat. Fury in his work did not agree to a similar work by Biot, published by him in 1804. With Biot there were Laplace and later Poisson. Later, in 1812, the analytical theory of thermal conductivity, presented by Fourie, won the Grand Prize of the Academy. However, the greatest mastery was achieved only in the era of Hilbert.
His methods (Four's series and integrals) are consistent with the theory of expansion of heat. All the same, the stench has become, in particular, a powerful tool for the mathematical investigation of various tasks - especially where there are husks and rocks. And this is incredibly broad - astronomy, acoustics, theory of tides, radio engineering, etc.
In 1818, Fur's family began to work on the minds of the people using the method of numerical equations developed by Newton. Similar results were already obtained in 1768 by Murail. The results of this work were visible only 1831 years after the death of the deceased.

His theory of heat was still crying out for supers, Biot attributing it to his diet, and Poisson criticizing Fouret's mathematical approach and developing an alternative theory.
Scientific achievements
- Having proved the theorem about the number of active roots of the algebra, what lies between these boundaries (Four's Theorem 1796).
- Following on from the work of J. Murail, the study of the minds of Isaac Newton developed the method of numerical solution of calculations (1818).
- The monograph “Analytical Theory of Heat”, in which the study of thermal conductivity in solids and the development of methods for its integration across various bordering minds were given. Four'e's method is based on the given function in the form of trigonometric Four'e's series.

- Having proved that a sufficiently criss-crossed line, folded from sections of arcs of different curves, can be seen in a single analytical way.
- In 1823, Ørsted discovered the thermoelectric effect, showing that superposition has power by creating a thermoelectric element.
His name is included in the list of the greatest treasures of France, placed on the first page of the Eiffel Tower.
Jean Baptiste Joseph Fourie was born in Auxerre (Auxerre), the homeland of the Kravets. Having become an orphan from the eight-digit family. As if the lady, “noticing his talent and tenderness at the camp,” joked about him, giving a good recommendation to the local bishop. He sent the boy to the military school. Jean Baptiste went through his apprenticeship with amazing ease, and after graduating from school, he lost his depository there. In 1796, he received the chair of mathematical analysis at the famous Polytechnic School, and his lectures were characterized by precision and sophisticated style. “The stench was not collected,” regretfully states François Arago, Fur’ie’s biographer, and adds: “The secret of his publication lay in the master’s collection of abstract truths with useful additions and scant historical details that I draw They are made from original jers, so they are very rare "
In 1798, Four's family, together with Gaspard Monge and Berthollet, took part in Napoleon's Egyptian expedition, without realizing its expansionist character, making extensive recommendations for thorough agriculture and irrigation technology to Egypt. His diplomatic gift and his efforts to establish friendly relations with the Arabs helped to stop the bloodshed. Having turned around, I became involved in administrative activities and, at the same time, the theory of the expansion of heat in solids.
Practicality and methodicality have been tested more than once or twice. Axis and Jean Fourie - carefully introduced the differential level of thermal conductivity, starting to joke about his decision in the field of change, setting different boundaries of the mind. In general, intuition is valued more than methodicality - if elections are carried out incorrectly, practicality is most important. Fur'e ruining for sure. We began to represent mathematical functions by trigonometric series. Rows that form harmonious warehouses. Rows of Fur'e - that's how they're called. And I will first criticize the lack of rigor of the principles.
Why is Jean Fur'e pershovidkrivachem? What was original about the idea of replacing a function with a trigonometric series? Science theorists say that the formulas for calculating coefficients were known to the great Leonhard Euler, who, in the words of Tibo, wrote his immortal works with a child on his knees and a gut on his back. Euler gave their drafts by way of member-by-member integration in 1777, and published them in 1798. Even earlier, before the St. Petersburg mathematician, he said Clairaut (1757). Both the one and the other vikorized them sporadically, hour after hour, and inexorably, Four'e's aims made them fit into the system. Trigonometric series dates back to Euler - in 1748, but it was only after Fourie that they became an ensign. We were the first to apply the laid out trigonometric series of functions, which are assigned to different analytical calculations in different plots. Lord Kelvin called Father Four a “great mathematical poem.”
The last life of Jean Fourie, who was appointed permanent secretary of the Paris Academy of Sciences, took place at countless stages. American investigator E.T. Bell reveals that Fury has become unbearably talkative and, instead, continues his investigation by entertaining the public with boastful reports about those who are going to earn money.
Joseph Fourie, who was born in Auxerre, near France, came from a humble homeland. Orphaned at an early age, Joseph begins his education at the Cathedral School, run by a church music teacher. After this, Fury continued his studies at the Royal Military School of Auxerre. The boy shows an extraordinary talent for literature, but in 15 years this talent obscures the skill for mathematics, which will drown one’s soul. Before his forty-nine birthdays, Joseph will have completed Bezout’s “Course of Mathematics”, and at the end of his life, he will retract his first letter to Bossu’s book “Fundamentals of Mechanics”.
U 1787 r. Fur'ie becomes a novice at the Benedictine Abbey of St. Benoit-sur-Loire, we are about to get a haircut from the Cheng. However, he reluctantly changes his plans, sending his scientific notes from algebra to Jean Montucla to Paris and declaring in a letter addressed to Bonard, his goal to make significant contributions to the developments of mathematics. Such actions reveal Four's doubts about whether he really wants to leave worldly life. U 1789 r. Fury goes to Paris, where he presents his paper on the topic of algebra at the Royal Academy of Sciences.
The coming fate of Fur'e embraces the seat of a young student at the Benedictine College - the Royal Military School in Auxerre, where he began to win himself.
Before the dilemma of whether to dedicate one’s life to serving God or to seriously study mathematics, another politics arises when Fouriet takes over the leadership of the local Revolutionary Committee. Turning to the city of Auxerre, Joseph contributes to colleges and works in the committee. U 1794 r. You should be arrested, otherwise you will be released into the wild. Through the river, which is headed by Vischu normal school of Paris - the initial investment that prepares depositors - de Vin, of course, appears to be the most successful among students. Joseph begins with the greatest compilers of his time - Lagrange, Laplace and Monge. Later, Fur'ie himself became a cash depositor at the Collège de France. With his teachers, he saves a good hundred dollars and, with their help, begins his journey to great mathematical achievements. The truck is quickly pushed through by service gatherings, removing the deposit from the Central School of State Works, which will soon be renamed to the Polytechnic School. However, in this old criminal case, new situations are opening up, as a result of which Furya is arrested again and tied up. It’s not too soon, and soon you’ll stumble upon freedom again.
Late period
1st Veresnya 1795 r. The transport starts again before the end of the day at the Polytechnic School. Two years later, in 1797, he replaced Lagrange as head of the department of analysis and mechanics. Regardless of those that Fourie has begun to establish himself as a distinguished lecturer, he will no longer engage in serious follow-up work. In 1798, at the time of the invasion of Egypt, Fourie became a scientific base under Napoleon's army. Although this military company was initially extremely successful, the French fleet suffered further defeats. Napoleon appears with a sharpened edge, as if he had buried. With the help of Fourie, he establishes here a typical French political system and administration. Fur is also involved in the discovery of initial deposits in Egypt and the organization of archaeological excavations. Kaira has been helping to establish the Cairo Institute, and she is one of the twelve members of its mathematical department, instructed by Monge, Malus and Napoleon himself. Relying on the weak English influx at the Assembly, he wrote a number of mathematical articles. Later, Fur became the scientific secretary of the Institute and remained in this position throughout the entire period of the French occupation of Egypt. His publication also has many scientific and literary works.
At 1801 r. Fury turns back to Paris and takes up his extra position as head of the department of analysis at the Polytechnic School. Prote Napoleon Mav on his new plans. The route goes to Grenoble, where he is appointed prefect of the department of Isère. He has been working on a number of projects for a long time, including the visible operation of draining the city of Bourgoin and monitoring the functioning of the new road from Grenoble to Turin. Here Fur himself draws his conclusions from the “extension of heat.” On April 21, 1816, at the Paris Institute, he presented to the scientific public his article “Thermal conductivity of solids”, which would lead to the monumental French publication “Description of Egypt”. Whose fate is it to destroy before England, turning from which, after six fates, replace Jean Baptiste Joseph Delambre as Permanent Secretary of the French Academy of Sciences.
Praci Fur'ie
In 1822, Fourie presented his article on the topic of heat flow under the title “Théorie analytique de la chaleur” (“Analytical theory of heat”). Based on Newton's law of cooling, Fourth worked out that the heat flow between two adjacent molecules is directly proportional to the small difference between their temperatures. The robot had three aspects: one mathematical and two physical. From a mathematical point of view, Fourth argues that any function that is variable, either continuous or disruptive, can be laid out in a series of sinuses that are multiples of the variable. Although this assertion was not true, the idea that certain distinct functions are given by formulas that would include endless rows became a sign of great importance. p align="justify"> Among the physical concepts of the robot there was a theory of uniformity of dimensions of the alignment, therefore, formally, the alignment can only be correct if the dimensions in both parts of the alignment are equal huddle. Another significant contribution of Four's to the developments of physics was the proposal of a water differential equation in private approaches for thermal conductivity. Until this day, the whole world knows a student who studies mathematical physics.
Before all the over-reinsurance, we can add Fur'e's unfinished work on the theme of the Rivne, which the victors took revenge on in 1831. finish and see Claude-Louis Navier. This work presents Four'ie's theorem for calculating the number of active roots of algebra. In addition to mathematical conclusions, Fur is the first to propose the theory of the greenhouse effect. Having completed the necessary developments, we can conclude that if the Earth was warmed by the sun’s vibrations, then, regardless of its size and rise to the Sun, on our planet it would be much colder. Based on this, it is necessary to come to the conclusion that a significant portion of additional heat is removed by the planet due to interplanetary radiation. This idea that the Earth's atmosphere acts as a kind of insulating ball was the first theory in the history of a phenomenon known to us today as the greenhouse effect. Relying on the evidence of Ferdinand de Saussure, Fourie suggests that gases in the atmosphere can create a strong barrier, like a glassy greenhouse, which lays the foundation for the current theory of the greenhouse effect.
Death is a mess
In 1830 r. Fur's health is deteriorating sharply. The first symptoms of a heart aneurysm appear just before the time of stay in Egypt and Grenoble, and after returning to Paris, the attacks of the poison become increasingly important. All this compiles the fall of Fur'e from the gatherings that took place on the 4th of May 1830 r. Within a few days, on May 16, 1830, Fur died. Pokhovaniya ceremonies at the center of Père Lachaise in Paris. His grave is decorated in the Egyptian style as a sign that he was the secretary of the Cairo Institute, as well as a reminder of his contribution in the book “Description of Egypt”. The name of Four is on the list of 72 two names of prominent people of France, recognized in the first version of the Eiffel Age.
