Default An enormous troll blunder.

If we place x'=x-vt, it is clear that a point at rest in the system k must
have a system of values x', y, z, independent of time.
xi = (x-vt) / sqrt(1-v^2/c^2)
xi = x' * beta where beta = 1/sqrt(1-v^2/c^2)

He [Einstein] wrote the lowercase greek letter Xi instead of x', -- Sylvia

What a way to begin a new year - change Einstein's notation and then change
its meaning.
Poor sick sad Sylvia the psychopathic bigot.
