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

„Besides these improvements,… there are others,… which may… be interesting to those… engaged in those departments… Among these may be ranked, in the division of mechanics, properly so called, a simple demonstration of the law of the force by which a body revolves in an ellipsis; another of the properties of cycloidal pendulums; an examination of the mechanism of animal motions; a comparison of the measures and weights of different countries; and a convenient estimate of the effect of human labour: with respect to architecture, a simple method of drawing the outline of a column: an investigation of the best forms for arches; a determination of the curve which affords the greatest space for turning; considerations on the structure of the joints employed in carpentry, and on the firmness of wedges; and an easy mode of forming a kirb roof: for the purposes of machinery of different kinds, an arrangement of bars for obtaining rectilinear motion; an inquiry into the most eligible proportions of wheels and pinions; remarks on the friction of wheel work, and of balances; a mode of finding the form of a tooth for impelling a pallet without friction; a chronometer for measuring minute portions of time; a clock escapement; a calculation of the effect of temperature on steel springs; an easy determination of the best line of draught for a carriage; an investigation of the resistance to be overcome by a wheel or roller; and an estimation of the ultimate pressure produced by a blow.“

—  Thomas Young (scientist)
A Course of Lectures on Natural Philosophy and the Mechanical Arts (1807), Preface

„This statement appears to us to be conclusive with respect to the insufficiency of the undulatory theory, in its present state, for explaining all the phenomena of light. But we are not therefore by any means persuaded of the perfect sufficiency of the projectile system: and all the satisfaction that we have derived from an attentive consideration of the accumulated evidence, which has been brought forward, within the last ten years, on both sides of the question, is that of being convinced that much more evidence is still wanting before it can be positively decided. In the progress of scientific investigation, we must frequently travel by rugged paths, and through valleys as well as over mountains. Doubt must necessarily succeed often to apparent certainty, and must again give place to a certainty of a higher order; such is the imperfection of our faculties, that the descent from conviction to hesitation is not uncommonly as salutary, as the more agreeable elevation from uncertainty to demonstration. An example of such alternations may easily be adduced from the history of chemistry. How universally had phlogiston once expelled the aërial acid of Hooke and Mayow. How much more completely had phlogiston given way to oxygen! And how much have some of our best chemists been lately inclined to restore the same phlogiston to its lost honours! although now again they are beginning to apprehend that they have already done too much in its favour. In the mean time, the true science of chemistry, as the most positive dogmatist will not hesitate to allow, has been very rapidly advancing towards ultimate perfection.“
