Lorentz transformation
The Lorentz transformations is a set of equations that describe a linear transformation between a stationary reference frame and a reference frame in constant velocity. The equations are given by
[math]\displaystyle{ x'=\frac{x-vt}{\sqrt{1-\frac{v^2}{c^2}}} }[/math] , [math]\displaystyle{ y'=y }[/math] , [math]\displaystyle{ z'=z }[/math] , [math]\displaystyle{ t'=\frac{t-\frac{vx}{c^2}}{\sqrt{1-\frac{v^2}{c^2}}} }[/math]
