Brightness Quote by Henrietta Swan Leavitt
“A straight line can readily be drawn among each of the two series of points corresponding to maxima and minima, thus showing that there is a simple relation between the brightness of the variables and their periods.”
About This Quote
Source Scientific Paper: 1908 Study on Cepheid Variable Stars
A straight line relates the brightness and period of variable stars, showing a simple proportionality.
In simple terms: Brightness and period are directly linked.
Key Takeaway
Use this relation to measure cosmic distances.

![“[It] may be laid down as a general rule that, if the result of a long series of precise observations approximates a simple relation so closely that the remaining difference is undetectable by observation and may be attributed to the errors to which they are liable, then this relation is probably…” quote by Pierre-Simon Laplace](https://sms4smile.com/quotes/img-quotes/1b9/pierre-simon-laplace-15849_differences_it-may-be-laid-down-as-a-general-rule-th_2647235.jpg)
