Early Evolution of Coincidence Counting a Fundamental Method in Cosmic Ray PhysicsThe roots of the coincidence method introduced in Cosmic Ray physics by Bothe and Kolhörster (1929) can be traced back to Professor Geiger’s laboratory for radioactivity in the former “Physikalisch-Technische-Reichsanstalt” in Berlin.

The Early Stage of Cosmic Ray Particle ResearchWhat follows is a brief account of “personal recollections” pertaining to the pre-history of cosmic-ray research, written by probably the oldest living participant of the scientific events of that period.

The Institute rose among olive trees, on the hill of Arcetri, a short distance from the villa where Galileo had spent the last years of his life as a political exile. The chair of physics was held by Professor Antonio Garbasso (Fig. 1) who, in earlier years, had done s

Keeping this in mind, the author does not intend to emphasize unduly the importance of a particular German effort but only to be reminiscent of some personal impressio

This arises partly from the difficulty of detecting the radiation in the first place but also from the wholly unexpected nature of the many phenomena encountered. Almost everyone in the game made mistakes. These involved errors not only in the taking of the da

Erratum to: Zusammengesetzte Gleichungen by Lord Rutherford for work in the Cavendish Laboratory, Cambridge. Being interested in instruments, I spent much of my time perfecting the gold-leaf tilted electroscope of C.T.R. Wilson. Eventually I produced a very quick-acting, critically damped quartz-fiber**electroscope with sensitivity limite

Vorlesungen über Maschinenelementewas gradually driven into oblivion by the advent of the new accelerators. Because of my health, I have not had access to a library except under very trying and difficult circumstances, and hence this paper was prepared at my home, based wholly on a limited amount of material and my own recollections
