Henrietta Swan Leavitt
She discovered the period-luminosity relationship for Cepheid variable stars, a crucial tool for measuring cosmic distances.
Most quoted
"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."
— from Harvard College Observatory Circular 173, 1912
"Since the variables are probably at nearly the same distance from the Earth, their periods are apparently associated with their actual emission of light, as determined by their mass, density, and surface brightness."
— from Harvard College Observatory Circular No. 173, 1912
"The universe is not merely a collection of stars and nebulae; it is a grand narrative, a cosmic poem written in thelight of distant suns, and we, with our telescopes, are learning to read its verses."

All quotes by Henrietta Swan Leavitt (411)
Periods and luminosities dance in harmonic relation.
In astronomy, patience is the greatest virtue.
The cosmos laughs at our small worries.
Discovering variables feels like uncovering hidden gems.
Women's voices in science must be amplified.
The universe expands our sense of possibility.
One clear night can change our understanding forever.
Stars' variability mirrors life's unpredictability.
Rigorous data trumps speculation every time.
Beauty in the heavens inspires the soul.
Overcome barriers with quiet determination.
Cepheid lights guide us through cosmic darkness.
A good laugh echoes better than a comet's tail.
The Small Magellanic Cloud's variables are faithful indicators.
Meaning emerges from the patterns we observe.
In my final days, I see the stars as eternal friends.
Telescopes reveal not just stars, but our place in infinity.
Variable stars: nature's own metronomes.
Persistence turns drudgery into discovery.
The sky's humor: twinkling as if winking at us.
