A goal is to place the physics underlying the operation of the Franck-Hertz experiment within the context of contemporary gaseous electronics, and to that end we reach back even further in time to the 1872 kinetic equation of Ludwig Boltzmann. We also show how the experiment can be modelled ...
The One Hertz launches as a limited edition with the name “One Hertz 1912”. This was the year Tim and Bart’s grandfather started his career as a watchmaker. The name Grönefeld and the art of watchmaking have a family history spanning nearly one hundred years, representing a continuous,...

However, in FMCW lidar systems, especially those installed on airborne platforms, the engine and other mechanical equipment generate much more severe vibrations with frequencies of up to several hundred hertz. In this case, the velocity of vibration is time-varying for fast vibrations, which de...
