Скачать или смотреть Day 30 - The Silent Pulse: (How a $0.30-an-Hour Clerk Mapped the Cosmos)

In 1908, a woman paid less than a secretary discovered the key to measuring the universe. Her boss took the credit. Her name was erased. And yet, every image of a distant galaxy, every calculation of cosmic expansion, rests on the simple law she found in the stars' heartbeat.

The human "computer" who:
•Discovered the Period-Luminosity Law for Cepheid variable stars—astronomy's most crucial "standard candle"
•Gave science the first reliable yardstick to measure interstellar distances
•Made it possible for Edwin Hubble to prove the existence of other galaxies and discover the expanding universe
•Was paid 30 cents an hour for her groundbreaking work
•Had her discovery announced under her male director's name
•Died in obscurity while her work revolutionized cosmology

She found the rhythm of the cosmos. The world forgot the drummer.
