    "abstract": "The history is described of how one of the most commonly used electric\ncircuit components, an ordinary electric contact, has become a powerful tool\nfor the physicists to study various mechanisms of electron scattering in\nmetals. The physical principles of spectroscopy of quasi-particle excitations\nin metals by means of point contacts (PCs) whose dimensions range from only a\nfew to tens of nanometers are presented in a popular form.",
