1 Introduction Ancient Greek philosophers used to speculate (as early as 500 BC) on whether matter could be divided at infinitum ...
The most radical revolution, however, was quantum mechanics. The key experiments that were crucial in the development of quantum ...
Instead of Joules (J), one often uses electron-volts (eV) to express energy; the two are related by 1eV = 1. 60219 × 10 −^19 J. ...
1.4 Reductionism The success of modern science, including physics, is due to ever advancing experimentation, as well as to the s ...
2 Two-state quantum systems The configuration of a quantum system is described in terms of a quantum state. The bound states of ...
Figure 1: Polarizer and analyzer set-up A more elaborate tool is abirefringent plate, which may again be inserted into the beam ...
2.2 Polarization of photons The entire discussion of the preceding subsection has concentrated on the behavior of classi- cal wa ...
Figure 3: Experiment with two birefringent plates found after the analyzer will beNcos^2 (θ−α). Translated into probabilities, t ...
In our context, these are given byax= cosθ,ay= sinθ, anda′x= cosα,a′y= sinα. The total amplitude results from linearly combining ...
