The experiments determine some of the fundamental constants (Planck constant, e/m of electron, gravitational constant, Rydberg constant, Boltzmann constant) or quantitatively demonstrate some of the concepts (quantum analog, Single photon interference) and applications (Thermionic emission, Solar Cells) of quantum physics. Also there are experiments that illustrate applications of thermodynamics (Johnson Noise, thermoelectric effect and Peltier effect), and non-linear dynamics (chaos). The lectures consist of introduction to error analysis and essential tools of modern experiments (vacuum and low temperatures), discussion of experiments leading to quantum mechanics and a brief introduction to other experiments carried out in the lab.
