The cutting edge sequence is aimed toward making the nice works of medical discovery available to scholars and lay readers. for every quantity, unusual historians of technological know-how have rigorously chosen unique texts (or extracts) and followed them with interpretive observation, explanatory notes, and bio-bibliographical fabric. those volumes usually are not synopses or histories to take where of the unique works. as an alternative, they permit non-specialists to learn those classics for themselves and take an lively half in learning the thrill of medical discovery.
Newton first published his medical genius in his pathbreaking paintings on optics and the homes of sunshine. via Newton’s early 1672 letter to the Royal Society and lengthy extracts from his mature paintings, Opticks (1704), the reader can persist with Newton’s personal descriptions of his experiments on prisms and movies, his arguments approximately white and coloured mild and the “particle” nature of sunshine, and his influential feedback on clinical technique. Dennis Sepper’s deft commentaries, diagrams, and notes support make clear problems that smooth readers are apt to come across in Newton’s language and technology. Sepper additionally presents an enticing caricature of Newton’s existence, the medical heritage to those discoveries, and their aftermath.
The exploration of the 1st billion years of the historical past of the Universe represents one of many nice demanding situations of latest astrophysics. in this time, the 1st constructions begin to shape the 1st stars, galaxies, and probably additionally quickly the 1st quasars. while, mild involves the darkish, impartial Universe. This e-book comprises the labored out lectures given on the thirty sixth Saas-Fee complex direction "First gentle within the Universe" through 3 eminent scientists within the field.

Die ganzen 50 Jahre bewußter Grübelei haben mich der Antwort der Fra ge »Was sind Lichtquanten" nicht näher gebracht. Heute glaubt zwar jeder Lump, er wisse es, aber er täuscht sich ... ALBERT EINSTEIN (in einem short an M. BESSO vom Jahre 1951) Erfahrungsgemäß fällt es uns nicht leicht, uns von der aus unmittelbarem Erleben geborenen Vorstellung zu trennen, daß ein jedes Ding bestimmte, über längere Zeiten unveränderliche Eigenschaften besitzt, die einander nicht widersprechen. Bekanntlich wurde dieses scheinbar so fest gefügte Weltbild nachhaltig durch die Quantenmechanik erschüttert, die aufzeigte, daß je denfalls im Mikrokosmos eine Einordnung der Dinge in säuberlich getrennte Schubfächer nicht möglich ist. Sie lehrt uns, daß die elementaren Objekt- und dazu zählt auch das Licht - eine verblüffende Gabe der Verwandlung besitzen: Einmal erscheinen sie uns als Welle und einmal als Teilchen. Heutzutage ist die Optik wie keine andere Disziplin dazu geeignet, uns diesen Dualismus unmittelbar, und dazu noch im Wortsinn, vor Augen zu führen.
