Walther Bothe and Bruno Rossi: the birth and development of coincidence methods in cosmic-ray physics
Walther Bothe and Bruno Rossi cosmic-ray physics
2011/8/31
In 1924 Walther Bothe and Hans Geiger applied a coincidence method to the study of Compton scattering with Geiger needle counters. Their experiment con rmed the existence of radiation quanta and estab...
This is a short essay I wrote for an online publication affiliated with the business school at the University of Technology, Sydney. I discuss how the methods used in physics can apply to economics in...
Theoretical Analysis of Formation and Sustainment Methods for Compact Toroids
Theoretical Analysis Formation and Sustainment Methods Compact Toroids
2010/10/27
Recent theoretical studies on the use of neutral beams (NB), rotating magnetic fields (RMF) and helicity injection (HI) to form and sustain compact toroids are reported. A Monte Carlo code was employe...
Comparing the Mori Formalism and the Green Function Methods
the Mori Formalism the Green Function Methods
2010/10/26
Using a simple model described by a Hamiltonian of fermions coupled to bosons, we show that the relaxation function calculated via a low temperature approximation to the Mori memory function is simila...
