Sometimes c is used for the speed of waves in any material medium, and c 0 for the speed of light in vacuum. [10] This subscripted notation, which is endorsed in official SI literature, [ 11 ] has the same form as related electromagnetic constants: namely, μ 0 for the vacuum permeability or magnetic constant, ε 0 for the vacuum permittivity ...

In SI units, the values of c, h, e and k B are exact and the values of ε 0 and G in SI units respectively have relative uncertainties of 1.6 × 10 −10 [16] and 2.2 × 10 −5. [17] Hence, the uncertainties in the SI values of the Planck units derive almost entirely from uncertainty in the SI value of G.

Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).
While c is an absolute upper bound to propagation speed, the maximum speed of a spaceship in Conway's Game of Life is c/2. [2] This is because it is impossible to build a spaceship that can move every generation. (This is not true, though, for cellular automata in general; for instance, many light-speed spaceships exist in Seeds.) It is ...
