Пьер-Симо́н, маркиз де Лапла́с — французский математик, механик, физик и астроном; известен работами в области небесной механики, дифференциальных уравнений, один из создателей теории вероятностей. Заслуги Лапласа в области чистой и прикладной математики и особенно в астрономии громадны: он усовершенствовал почти все разделы этих наук.

Лаплас состоял членом шести академий наук и королевских обществ, в том числе Петербургской Академии , и членом Французского Географического общества. Его имя внесено в список величайших учёных Франции, помещённый на первом этаже Эйфелевой башни.

Цитаты Пьер-Симон Лаплас

„... в этой гипотезе я не нуждался.“

— Пьер-Симон Лаплас
Наполеон как-то спросил: «Ньютон в своей книге говорил о Боге, в Вашей же книге я не встретил имени Бога ни разу». Лаплас ответил: «Гражданин первый консул, в этой гипотезе я не нуждался»

„Given for one instant an intelligence which could comprehend all the forces“

— Pierre-Simon Laplace
Context: Given for one instant an intelligence which could comprehend all the forces by which nature is animated and the respective situation of the beings who compose it—an intelligence sufficiently vast to submit these data to analysis—it would embrace in the same formula the movements of the greatest bodies of the universe and those of the lightest atom; for it, nothing would be uncertain and the future, as the past, would be present to its eyes. The human mind offers, in the perfection which it has been able to give to astronomy, a feeble idea of this intelligence. Its discoveries in mechanics and geometry, added to that of universal gravity, have enabled it to comprehend in the same analytical expressions the past and future states of the system of the world.<!--p.4

„All these efforts in the search for truth tend to lead it“

— Pierre-Simon Laplace
Context: All these efforts in the search for truth tend to lead it [the human mind] back continually to the vast intelligence... but from which it will always remain infinitely removed. This tendency peculiar to the human race is that which renders it superior... and their progress in this respect distinguishes nations and ages and constitutes their true glory.<!--pp.4-5

„The theory of chance consists in reducing all the events of the same kind to a certain number of cases equally possible“

— Pierre-Simon Laplace
Context: The theory of chance consists in reducing all the events of the same kind to a certain number of cases equally possible, that is to say, to such as we may be equally undecided about in regard to their existence, and in determining the number of cases favorable to the event whose probability is sought.<!--p.6

„Imaginary causes have gradually receded with the widening bounds of knowledge“

— Pierre-Simon Laplace
Context: Imaginary causes have gradually receded with the widening bounds of knowledge and disappear entirely before sound philosophy, which sees in them only the expression of our ignorance of the true causes.<!--p.3

„Translation: "Read Euler, read Euler, he is the master of us all." (Sometimes freely translated as: "Read Euler: he is our master in everything.")“

— Pierre-Simon Laplace
Reported by Gugliemo Libri in the Journal des Savants, January 1846, p. 51: « ...ces paroles mémorables que nous avons entendues de sa propre bouche : "Lisez Euler, lisez Euler, c'est notre maître à tous". »

„Translation: "It is therefore obvious that..."“

— Pierre-Simon Laplace
Frequently used in the Traité de mécanique céleste when he had proved something and mislaid the proof, or found it clumsy. Notorious as a signal for something true, but hard to prove.

„The most important questions of life... are indeed for the most part only problems of probability.“

— Pierre-Simon Laplace
Context: The most important questions of life... are indeed for the most part only problems of probability. Strictly speaking it may even be said that nearly all our knowledge is problematical; and in the small number of things which we are able to know with certainty, even in the mathematical sciences themselves, the principal means for ascertaining truth—induction and analogy—are based on probabilities.<!--p.1

„Translation: "Man follows only phantoms."“

— Pierre-Simon Laplace
His true last words, according to Augustus De Morgan's Budget of Paradoxes (1866). Compare Edmund Burke's famous remark, after a parliamentary candidate's sudden death, about "what shadows we are, and what shadows we pursue".

„Translation: "The last thing we expect of you, General, is a lesson in geometry!"“

— Pierre-Simon Laplace
Laplace to Napoléon, after the latter had reported on some new elementary geometry results
