The Structure of the Universe: An Introduction to Cosmology (1949)
Let an observer B on the star estimate the distance and epoch of the nova outburst to be x<nowiki>'</nowiki> units of length and t<nowiki>'</nowiki> units of time, respectively. Then the Lorentz formulae, relating x<nowiki>'</nowiki> to t<nowiki>'</nowiki>, are<center><math>x' = \frac {x-vt}{\sqrt{1-\frac{v^2}{c^2}}} ; \qquad t' = \frac {t-\frac{vx}{c^2}}{\sqrt{1-\frac{v^2}{c^2}}}</math></center>
These formulae are... quite general, applying to any event in line with two uniformly moving observers. If we let c become infinite then the ratio of v to c tends to zero and the formulae become<center><math>x' = x - vt ; \qquad t' = t</math></center>.

“From which stars have we fallen to meet each other here?”

“It is time that we steered by the stars, not by the lights of each passing ship.”
Statement (31 May 1948), quoted in An Inconvenient Truth : The Planetary Emergency Of Global Warming And What We Can Do About It (2006) by Al Gore
“Two men looked out from prison bars,
One saw the mud, the other saw stars.”
