Charles Francis Richter in southern California. Since 1935, several other magnitude scales have been developed. Richter was an active and avowed naturist. He travelled to many nudist communities with his wife. At his retirement party, a group of colleagues at Caltech, called the "Quidnuncs," played and sang a ditty titled "Richter Scale," which gave examples of earthquakes in American history, told in ballad style. Richter was not amused, however; he was furious. The author of the song, Kent Clark, stated in a 1989 interview that Richter enjoyed the song. The song is played on the Dr. Demento show occasionally. Richter died of congestive
Macroscopic scale particles with lower mass-energies are also part of high energy physics; they also have a mass-energy that is far higher than that at the macroscopic scale (such as electrons), or are equally involved in reactions at the particle level (such as neutrinos). Relativistic effects, as in particle accelerators and cosmic rays, can further increase the accelerated particles' energy by many orders of magnitude, as well as the total energy of the particles emanating from their collision and annihilation. Macroscopic scale The macroscopic scale is the length scale on which objects or phenomena are large enough to be visible almost practically
