Gaspard Monge was born at Beaune on May 10, 1746, and died at Paris on July 28, 1818. He was the son of a small pedlar, and was educated in the schools of the Oratorians, in one of which he subsequently became an usher. A plan of Beaune which he had made fell into the hands of an officer who recommended the military authorities to admit him to their training school at Mézières. His birth, however, precluded his receiving a commission in the army, but his attendance at an annexe of the school where surveying and drawing were taught was tolerated, though he was told that he was not sufficiently well born to be allowed to attempt problems which required calculation. At last his opportunity came. A plan of a fortress having to be drawn from the data supplied by certain observations, he did it by a geometrical construction. At first the officer in charge refused to receive it, because etiquette required that not less than a certain time should be used in making such drawings, but the superiority of the method over that then taught was so obvious that it was accepted; and in 1768 Monge was made professor, on the understanding that the results of his descriptive geometry were to be a military secret confined to officers above a certain rank.
In 1780 he was appointed to a chair in mathematics in Paris, and this with some provincial appointments which he held gave him a comfortable income. The earliest paper of any special importance which he communicated to the French Academy was one in 1781, in which he discussed the lines of curvature drawn on a surface. These had been first considered by Euler in 1760, and defined as those normal sections whose curvature was a maximum or a minimum. Monge treated them as the locus of those points on the surface at which successive normals intersect, and thus obtained the general differential equation. He applied his results to the central quadrics in 1795. In 1786 he published his well-known work on statics.
Monge eagerly embraced the doctrines of the revolution. In 1792 he became minister of the marine, and assisted the committee of public safety in utilizing science for the defence of the republic. When the Terrorists obtained power he was denounced, and escaped the guillotine only by a hasty flight. On his return in 1794 he was made a professor at the short-lived Normal school, where he gave lectures on descriptive geometry; the notes of these were published under the regulation above alluded to. In 1796 he went to Italy on the roving commission which was sent with orders to compel the various Italian towns to offer pictures, sculpture, or other works of art that they might possess, as a present or in lieu of contributions to the French republic for removal to Paris. In 1798 he accepted a mission to Rome, and after executing it joined Napoleon in Egypt. Thence after the naval and military victories of England he escaped to France.
Monge then settled down at Paris, and was made professor at the Polytechnic school, where he gave lectures on descriptive geometry; these were published in 1800 in the form of a textbook entitled Géométrie descriptive . This work contains propositions on the form and relative position of geometrical figures deduced by the use of transversals. The theory of perspective is considered; this includes the art of representing in two dimensions geometrical objects which are of three dimensions, a problem which Monge usually solved by the aid of two diagrams, one being the plan and the other the elevation. Monge also discussed the question as to whether, if in solving a problem certain subsidiary quantities introduced to facilitate the solution become imaginary, the validity of the solution is thereby impaired, and he shewed that the result would not be affected. On the restoration he was deprived of his offices and honours, a degradation which preyed on his mind and which he did not long survive.
Most of his miscellaneous papers are embodied in his works, Application de l'algèbre à la géométrie , published in 1805, and Application de l'analyse à la géométrie , the fourth edition of which, published in 1819, was revised by him just before his death. It contains among other results his solution of a partial differential equation of the second order.
Latar Belakang dan Pengantar Penulis
Gaspard Monge adalah seorang matematikawan dan ilmuwan Prancis yang luar biasa yang lahir pada tahun 1746 di Beaune, Prancis. Berasal dari latar belakang yang sederhana sebagai putra seorang pedagang kecil, kisah hidup Monge adalah kisah tentang tekad dan kecemerlangan intelektual yang mengatasi hambatan sosial. Terlepas dari rintangan awal karena status kelahirannya, ia mengejar pendidikan dengan penuh semangat dan dengan cepat membedakan dirinya di bidang geometri dan matematika. Karyanya meletakkan dasar bagi geometri deskriptif, cabang matematika yang membantu kita merepresentasikan objek tiga dimensi dalam dua dimensi—keterampilan penting dalam teknik, arsitektur, dan seni.
Monge hidup melalui periode yang bergejolak dalam sejarah Prancis, termasuk Revolusi Prancis. Ia tidak hanya seorang ilmuwan tetapi juga seorang pelayan publik yang menggunakan pengetahuannya untuk mendukung pemerintahan revolusioner. Karirnya termasuk peran sebagai profesor, menteri, dan penasihat ilmiah untuk Napoleon. Kontribusinya terhadap matematika dan sains sangat terkait erat dengan perubahan sosial dan politik pada masanya.
Interpretasi dan Signifikansi Terperinci
Kisah Gaspard Monge bukanlah kisah fiksi tetapi narasi kehidupan nyata tentang ketekunan, inovasi, dan kekuatan pendidikan. Pengembangan geometri deskriptifnya merupakan terobosan dalam cara kita memvisualisasikan dan memecahkan masalah spasial. Metode ini memungkinkan bentuk tiga dimensi yang kompleks dipahami melalui gambar dua dimensi, yang sangat mendasar di banyak bidang saat ini.
Karya Monge tentang garis kelengkungan, statika, dan persamaan diferensial juga memajukan pemahaman matematika secara signifikan. Pendekatannya menggabungkan wawasan teoretis dengan aplikasi praktis, menunjukkan bagaimana matematika abstrak dapat memecahkan masalah dunia nyata. Lebih lanjut, perannya selama Revolusi Prancis menyoroti bagaimana sains dan politik dapat berpotongan, terkadang dengan risiko pribadi yang besar.
