Optical theory
WebContemporary theory held that the eye emitted a visual spirit, which created vision when reflected back from objects. Only after Galileo's (1564-1642) improved telescope of 1609 encouraged Johannes Kepler (1571-1630) to formulate modern optical theory in his book Dioptrice (Concerning measuring altitude, 1611) did the eye become accepted as an ... Webreal and imaginary parts. Likewise, in quantum field theory the tree-level amplitudes are real, — at least for the elastic scattering in the forward direction, — but the loop corrections make for complex amplitudes. The reason for this behavior is the optical theorem (21), plus power-of-the-coupling counting in the perturbation theory.

WebAn optical theory in his day was expected to pronounce on the nature of light, on the transmission of light from the Sun to the Earth, on reflection and refraction, and on the workings of optical instruments such as mirrors and lenses. Hobbes took up these topics in several relatively short treatises and in correspondence, including with ...
