Дата смерти: 10. Май 1829

То́мас Юнг — английский учёный широкого профиля: физик , механик, врач , астроном, филолог и востоковед . Полиглот — владел 13 языками. Учёный секретарь Королевского общества по переписке с заграницей . В 1801—1803 годах был профессором Королевского института в Лондоне. С 1818 года — секретарь Бюро долгот и редактор «Морского альманаха». Иностранный член Французской академии наук и Шведской королевской академии наук . Занимаясь египтологией, вплотную подошёл к расшифровке древнеегипетской иероглифики, в англоязычном мире именно Юнг, а не Шампольон, считается дешифровщиком египетского письма. За широту интересов и фундаментальность вклада в науку биограф Эндрю Робинсон охарактеризовал Юнга как «последнего человека, который знал всё».

Цитаты Томас Юнг

„Каждый может сделать то, что могут сделать другие.“

— Томас Юнг

„It is surprising that so great a mathematician as Dr. Smith could have entertained for a moment, an idea that the vibrations constituting different sounds should be able to cross each other in all directions, without affecting the same individual particles of air by their joint forces: undoubtedly they cross, without disturbing each other's progress; but this can be no otherwise effected than by each particle's partaking of both motions. If this assertion stood in need of any proof, it might be amply furnished by the phenomena of beats, and of the grave harmonics observed...“

— Thomas Young (scientist)

„A permanent alteration of form limits the strength of materials with regard to practical purposes, almost as much as fracture; since, in general, the force which is capable of producing this effect is sufficient, with a small addition, to increase it till fracture takes place.“

— Thomas Young (scientist)
(1807) Nat. Phil. Vol. i, p. 14. as quoted by Robert Henry Thurston, Materials of Engineering (1884) Part III https://books.google.com/books?id=0p1BAAAAIAAJ p. 548.

„With respect to the cohesion and of liquids, I have had the good fortune to anticipate Mr. Laplace in his late researches, and I have endeavoured to show, that my assumptions are more universally applicable to the facts, than those which that justly celebrated mathematician has employed.“

— Thomas Young (scientist)
Preface, p. viii

„have enumerated, in a compendious and systematical form, the principal facts which have been discovered with respect to galvanic electricity; and I have fortunately been able to profit by Mr. Davy's most important experiments, which have lately been communicated to the, and which have already given to this branch of science a much greater perfection, and a far greater extent, than it before possessed.“

— Thomas Young (scientist)
Preface, pp. viii-ix

„The passive of all kinds has been very fully investigated, and many new conclusions have been formed respecting it, which are of immediate importance to the architect and to the engineer, and which appear to contradict the results of some very elaborate calculations.“

— Thomas Young (scientist)
Preface, p. vii

„I have... attempted to throw some new light on the general properties of matter in other forms: and on the doctrine of heat, which is materially concerned in them; and to deduce some useful conclusions from a comparison of various experiments on the elasticity of s.“

— Thomas Young (scientist)
Preface, p. viii

„With respect to the mathematical part of optics, the curvature of the images, formed by lenses and mirrors, has been correctly investigated, and the inaccuracy of some former estimations has been demonstrated.“

— Thomas Young (scientist)
Preface, pp. vii-viii

„The theory of the tides has been reduced into an extremely simple form, which appears to agree better with all the phenomena, than the more intricate calculations which they have commonly been supposed to require.“

— Thomas Young (scientist)
Preface, p. viii

„The historical part of the work can scarcely be called new, but several of the circumstances, which are related, have escaped the notice of former writers on the history of the sciences.“

— Thomas Young (scientist)
Preface, p. ix

„The fundamental doctrines of motion have [herein]... been more immediately referred to axioms simply mathematical than has hitherto been usual; and the application of these doctrines to practical purposes has [herein]... been facilitated.“

— Thomas Young (scientist)
Preface (March 30, 1807), p. vii

„It may hereafter be considered how far the excellent experiments of Count Rumford, which tend very greatly to weaken the evidence of the modern doctrine of heat, may be more or less favourable to one or the other system of light and colours.“

— Thomas Young (scientist)

„The well known elevation of the pitch of wind instruments, in the course of playing, sometimes amounting to half a note, is not, as is commonly supposed, owing to any expansion of the instrument, for this should produce a contrary effect, but to the increased warmth of the air in the tube.“

— Thomas Young (scientist)

„When I was a boy, I thought myself a man. Now that I am a man, I find myself a boy.“

— Thomas Young (scientist)
as quoted by Horatio B. Williams, Thomas Young, The Man and Physician, J. Opt. Soc. Am. 20, 35-49 (1930).

„The arrangement of the whole work is probably different... from any other... the extent of the subjects... rendered it necessary to preserve a... methodical and uniform system; and it is presumed, that this arrangement will be... of some value, especially in a work calculated to serve as a key, by means of which, access may be obtained to all the widely scattered treasures of science; and which will enable those... desirous of extending their researches in any particular department, to obtain expeditiously all the information that books can afford them.“

— Thomas Young (scientist)
Preface, pp. x-xi

„I met with an accident about five weeks ago in London, which has prevented my walking ever since, and I think I broke one of the metatarsal bones; this has been a favourable circumstance, for it has increased my literary application in a considerable degree. I have been studying, not the theory of the winds, but of the air, and I have made observations on harmonics which I believe are new. Several circumstances unknown to the English mathematicians which I thought I had first discovered, I since find to have been discovered and demonstrated by the foreign mathematicians; in fact, Britain is very much behind its neighbours in many branches of the mathematics: were I to apply deeply to them, I would become a disciple of the French and German school; but the field is too wide and too barren for me.“

— Thomas Young (scientist)
Letter to Dr. Bostock (June, 1798) as quoted by George Peacock, Life of Thomas Young (1855)
