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

„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

„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

„In the department of, the phenomena of halos and parhelia have been explained, upon principles not entirely new, but long forgotten: the functions of the eye have been minutely examined, and the mode of its accommodation to the perception of objects at different distances ascertained: the various phenomena of coloured light have been copiously described, and accurately represented by coloured plates; and some new cases of the production of colours have been pointed out, and have been referred to the general law of double lights, by which a great variety of the experiments of former opticians have also been explained; and this law has been applied to the establishment of a theory of the nature of light, which satisfactorily removes almost every difficulty that has hitherto attended the subject.“

— Thomas Young (scientist)
Preface, p. viii

„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.“

— Thomas Young (scientist)
Preface, p. x

„[T]he lectures... may be expected to remain tolerably commensurate to the state of the sciences for a much longer period; since, in investigations so intimately connected with mathematical principles, the essential improvements will always bear a very small proportion to the number of innovations.... the references, which it contains, are... sufficient to lead those, who may consult the passages quoted, to the works of every author of eminence that has treated of the respective subjects.“

— Thomas Young (scientist)
Preface, p. xi

„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

„In the hydraulic and optical part, may be enumerated an over flowing lamp; a simplification of the rules for finding the velocity of running water; remarks on the application of force to hydraulic machines; a mode of letting out air from water pipes; an analysis of the human voice; and some arrangements for solar s, and for other optical instruments of a similar nature.“

— Thomas Young (scientist)
Preface

„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.“

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

„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

„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.“

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

„I have resolved to confine my studies and my pen to medical subjects only. For the talents which God has not given me, I am not responsible, but those which I possess, I have hitherto cultivated and employed as diligently as my opportunities have allowed me to do; and I shall continue to apply them with assiduity, and in tranquillity, to that profession which has constantly been the ultimate object of all my labours.“
