    «Since her death in 1979, the woman who discovered what the universe is made of has not so much as received a memorial plaque. Her newspaper obituaries do not mention her greatest discovery. […] Every high school student knows that Isaac Newton discovered gravity, that Charles Darwin discovered evolution, and that Albert Einstein discovered the relativity of time. But when it comes to the composition of our universe, the textbooks simply say that the most abundant atom in the universe is hydrogen. And no one ever wonders how we know.» — Jeremy Knowles, discussing the complete lack of recognition Cecilia Payne gets, even today, for her revolutionary discovery. (via alliterate)

    OH WAIT LET ME TELL YOU ABOUT CECILIA PAYNE

    • Cecilia Payne’s mother refused to spend money on her college education, so she won a scholarship to Cambridge.

    • Cecilia Payne completed her studies, but Cambridge wouldn’t give her a degree because she was a woman, so she said to heck with that and moved to the United States to work at Harvard.

    • Cecilia Payne was the first person ever to earn a Ph.D. in astronomy from Radcliffe College, with what Otto Strauve called “the most brilliant Ph.D. thesis ever written in astronomy.”

    • Not only did Cecilia Payne discover what the universe is made of, she also discovered what the sun is made of (Henry Norris Russell, a fellow astronomer, is usually given credit for discovering that the sun’s composition is different from the Earth’s, but he came to his conclusions four years later than Payne — after telling her not to publish).

    • Cecilia Payne is the reason we know basically anything about variable stars (stars whose brightness as seen from earth fluctuates). Literally every other study on variable stars is based on her work.

    • Cecilia Payne was the first woman to be promoted to full professor from within Harvard, and is often credited with breaking the glass ceiling for women in the Harvard science department and in astronomy, as well as inspiring entire generations of women to take up science.

    • Cecilia Payne is awesome and everyone should know her.

      #Cecilia Payne-Gaposchkin (née le 10 mai 1900 à Wendover en Angleterre et morte le 7 décembre 1979 à Cambridge dans le Massachusetts) est une astronome anglo-américaine. Elle est la première femme nommée cheffe du département d’astronomie de Harvard en 1956. Elle est notamment connue pour être, en 1925, une des premières astronomes à envisager que les étoiles soient composées majoritairement d’hydrogène, à l’encontre du consensus scientifique de l’époque.

      Did this Woman Really Discover What ’the Universe is Made of’? | Snopes.com

      Cecilia Payne (who went by Cecilia Payne-Gaposchkin most of her life) was instrumental in discovering the ubiquity of hydrogen in our universe, and the data she derived for her 1925 dissertation are likely the most significant contributions to our modern understanding of the true composition of stars. Despite this, she was, at the time, encouraged to downplay her paradigm-challenging results at the behest of men who would later verify them as accurate. That said, the viral post takes a few liberties. This article provides historical and scientific context about Payne-Gaposchkin, and then addresses each specific statement in the post.
