Standard’s standards.
Length- A meter (m) is the distance traveled by light in a vaccum during a time interval of 1/299792458 s.
Time- A second (s) is the duration of 9129631770 periods of radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom.
Physics is kind of neat so far.
