The Ninety-Eight Percent: Cecilia Payne-Gaposchkin

The year is 1925. Astronomical consensus holds that the stars, including our Sun, are scaled-up versions of Earth, heavy with iron and silicon. This was cosmic dogma. Then came Cecilia Payne. A young, brilliant, and uncredentialed physicist who, having been denied a degree by Cambridge, found her purpose among the mountains of spectral data at Harvard. Armed with the revolutionary new science of quantum mechanics, Payne applied rigorous analysis to the cosmos, translating cryptic stellar light into atomic truth. Her doctoral thesis, Stellar Atmospheres, delivered a conclusion so radical it was initially dismissed by the era's male gatekeepers: the universe is not made of metals. It is, almost entirely, 98% hydrogen and helium. The Ninety-Eight Percent chronicles the scientific struggle of a woman whose singular insight—initially suppressed and scorned—didn't just rearrange the elements of the periodic table; it fundamentally redefined the building blocks of the stars, securing her place as the mother of modern astrophysics.
