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 ...
