Johann Heinrich Lambert was born at Mülhausen on August 28, 1728, and died at Berlin on September 25, 1777. He was the son of a small tailor, and had to rely on his own efforts for his education; from a clerk in some ironworks he got a place in a newspaper office, and subsequently, on the recommendation of the editor, he was appointed tutor in a private family, which secured him the use of a good library and sufficient leisure to use it. In 1759 he settled at Augsburg, and in 1763 removed to Berlin where he was given a small pension, and finally made editor of the Prussian astronomical almanack.
Lambert's most important works were one on optics, issued in 1759, which suggested to Arago the lines of investigation he subsequently pursued; a treatise on perspective, published in 1759 (to which in 1768 an appendix giving practical applications were added); and a treatise on comets, printed in 1761, containing the well-known expression for the area of a focal sector of a conic in terms of the chord and the bounding radii. Besides these he communicated numerous papers to the Berlin Academy. Of these the most important are his memoir in 1768 on transcendental magnitudes, in which he proved that is incommensurable (the proof is given in Legendre's Géométrie , and is there extended to ): his paper on trigonometry, read in 1768, in which he developed Demoivre's theorems on the trigonometry of complex variables, and introduced the hyperbolic sine and cosine denoted by the symbols sinh x, cosh x: his essay entitled analytical observations, published in 1771, which is the earliest attempt to form functional equations by expressing the given properties in the language of the differential calculus, and then integrating his researches on non-Euclidean geometry: lastly, his paper on vis viva, published in 1783, in which for the first time he expressed Newton's second law of motion in the notation of the differential calculus.
约翰·海因里希·兰伯特的背景和介绍
约翰·海因里希·兰伯特是一位杰出的数学家和科学家,出生于18世纪,当时科学思想正在迅速扩展和发展。尽管兰伯特出身于裁缝的家庭,但他凭借决心和自学成才,最终成为了一位受人尊敬的学者。他的生平故事有力地证明了对学习的毅力和热情如何能够克服社会和经济障碍。
关于作者
兰伯特从在铁厂当职员到成为天文年历的编辑,展现了他对知识和科学的奉献精神。他很大程度上是自学成才的,这使得他的成就更加令人印象深刻。他的研究涵盖了许多领域,包括光学、几何学、三角学和天文学。他不仅是一位数学家,还是一位物理学家和哲学家,为现代科学的发展做出了重大贡献。
兰伯特贡献的详细解释
兰伯特在光学方面的研究具有开创性,并启发了后来的科学家,如阿拉戈。他关于透视法的论文帮助艺术家和科学家理解如何在二维表面上准确地呈现三维物体。他关于彗星的论文包含了重要的数学表达式,有助于描述彗星的路径。
他最著名的成就之一是证明了某些数字的无理性,这意味着这些数字不能表示为简单的分数。这是现代数学发展中的一个重要步骤。他还介绍了三角学中的重要概念,包括双曲正弦和余弦函数,这些函数在当今的许多科学和工程领域中至关重要。
兰伯特对非欧几里德几何学的探索走在了时代的前沿,为高斯和黎曼等未来的数学家奠定了基础。他使用微积分符号对牛顿定律的研究,帮助使物理学更加精确和数学严谨。
