Unformatted text preview: Gribbin Chapter 11 Until the end of 18 th century Newtons perception of light as a stream of particles dominated the wave model of light. Up to the early twentieth century Newtons statements was accepted as right, but after 20th century even his laws of motion were not the last word in mechanics. By the end of the eighteenth century bi ok gzlemler yaplm ve bunlar wave modelin olumasn salam. Newtondan nce bile varm bu gzlemlerin bazlar. An Italian physicist Francesco Grimaldi (1618-1663), professor of mathematics at the Jesuit college, studied light by letting a beam of sunlight into a darkened room through a small hole. (Bunu daha sonralar Newton da yapm)He found 1. Bu adam grmki k ikinci delikten geip ekrana kavuunca saakl bir grnm salyor ve bu sacaklar direk gelen n oluturcandan daha genimi. Demiki the light had been bent outwards slightly as it passed through the hole bunun adnada diffraction koymu =) 2. when a small object was placed in the beam of light, the shadow cast by the object had coloured edges where light had been diffracted around the edge of the object and leaked into the shadow. ( buda n dalga gibi yayldnn rnei oluyormu) bu shadowa parantez amak lazm o parantezide yle doldurmak lazm (The fringes are coloured, like a rainbow, because different wavelengths of light are bent by different amounts, and different wavelengths correspond to different colours) Bu herif bu dnceleri adam ldkten 20 yl sonra Physico-mathesis de lumine, coloribus, et hide ; denen kitapta yaynlanm. Tabi adam ldnden dncelerini savunmak yada gelitirmek iin orda yokmu. Bu deneylerde hasas lm filan gerektirdiinden kimse bunla ilgilenmek istememi. Galiba bu kitaptan sonra Newton fikrini wave modele doru deitirmi. 1727 de Newton ldkten sonra k teorileri hakknda dnmek btn yz yl domine etmi. Swiss mathematician Leonhard Euler introduced mathematical notations such as n, e and i , and he is also the archetypal example ofthe dangers of looking directly at the Sun. Salak sa gzn kaybetmi =) Daha sonrada katarakt tan dier gzn kaybetmi ama bunlar matematikle uramasn engellememi. Bu herif kla sesi badatrarak alm. 1760larda yazd mektupta kendini yle ifade etmi sunlight is 'with respect to the ether, what sound is with respect to air' and Sun as 'a bell ringing out light Joseph Lagrange (1736-1813), provided the basis for a mathematical description of the quantum world in the twentieth century. (nemsiz galiba adamdan bukadar bahsedilmi) 19th yzyla kadar hi kimse n yapsyla alakal bir dnce deiikliine gitmemi. Ta ki Thomas Young doana kadar....
