We all love things that are constant, predictable, with no surprises and as a consequence the world of Science is full of it... constants. Here's a few for illustration purposes:
Speed of light in vacuum
Gravitational constant Planck constant Electric constant / Vacuum Permittivity
Magnetic constant / Vacuum Permeability Cosmological constant There are loads of them used for the most varied purposes, from rocket launches to utilities meter readings. We tend to forget how they came about, the process that lead to the calculated figures above. It all started with measuring, collecting data from experiments, finding that there is a relationship between the measurements and the common factor between them all.
