Historically the equation of time ET, giving the difference between the solar mean time and true solar time, has been useful to improve estimates of latitudes. Today with GPS accurate positioning systems, and with accurate atomic clocks, the equation of time is seldom of practical use. It is nonetheless of interest from a basic physics standpoint because of its connection with Earth orbital...

The air fluorescence detection technique is widely used in ultra-high energy cosmic ray experiments to reconstruct the shower cascade profile and determine both the energy and arrival direction of the primary particle. Using the CORSIKA air shower simulation code, the evolution of extensive air showers induced by primary particles with energies reaching up to 100 EeV is modeled, considering...

When I speak of Metrology to people, they often think I’m talking about Meteorology …until they get very confused. That’s because Metrology – the science of measurement – despite playing a fundamental role in our everyday lives, is mostly working behind the scenes. Metrology is best known in industrial contexts, where interoperability and matching parts is paramount to doing business....
