Meanwhile, he also published his views and thoughts on mechanics, physical anatomy and calculus in many papers and journals. He also simultaneously focused on the philosophical and mathematical concepts of statistics and probability. ‘Celestial Mechanics’ is one of his notable books in which he has extended and summarized the work of his antecedents. Laplace’s method for approximating integrals and solution of the linear partial difference equation are few others of his most used contributions in the mathematics. Here are some notable quotes and thoughts by one of the greatest scientists of all time which have been excerpted from his works, life, journals, research papers and books.
