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».

„When I was a boy, I thought myself a man. Now that I am a man, I find myself a boy.“
— Thomas Young (scientist)

„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.“

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

Preface, pp. ix-x
„I have... begun to collect materials for a work... relating to every department of medical knowledge:... it will be comparatively more concise than these lectures, in proportion to what has been said and written respecting physic, but, I hope, much more complete, with regard to all that is known with certainty, and can be applied with utility.“

„The theory of waves has been much simplified, and somewhat extended, and their motions have been illustrated by experiments... A similar method of reasoning has been applied to the circulation of the blood, to the propagation of sound, either in fluids or in solids, and to the vibrations of musical chords; the general principle of a velocity, corresponding to half the height of a certain modulus, being shown to be applicable to all these cases: and a connexion has been established between the sound to be obtained from a given solid, and its strength in resisting a flexure of any kind; or, in the case of ice and water, between the sound in a solid and the compressibility in a fluid state. The doctrine of sound and of sounding bodies in general has also received some new illustrations, and the theory of music and of musical intervals has been particularly discussed.“
— Thomas Young (scientist)
Preface, p. vii
„Physic is one of those departments, in which there is frequent necessity for the exercise of an incommunicable faculty of judgment, and a sagacity, which may be called transcendental, as extending beyond the simple combination of all that can be taught by precept. Nor is there any other mode of cultivating these powers, than by pursuing a much more extensive range of elementary study, than appears, to a common and superficial observer, to be in any way connected with the immediate objects of the profession.“
— Thomas Young (scientist)
p. 5
„There is no study more difficult than that of physic: it exceeds, as a science, the comprehension of the human mind: and those who blunder onwards, without attempting to understand what they see, are often very nearly on a level with those, who depend too much on imperfect generalisations, applied to facts, which can scarcely be subjected to any well marked analogy. Hence it may happen, that talents and labour may become useless for want of a proper direction... To assist in furnishing the student with a sufficient direction... is the principal object of this work.“
— Thomas Young (scientist)
p. 2
„In the astronomical and physical division of the work, will be found a general rule for determining the correction on account of aberration; a comparison of observations on the; formulae for finding the heat of summer and winter; remarks on the theory of the winds; and a comparative table of all the mechanical properties of a variety of natural bodies.“
