Behind one of history's greatest scientific minds was a man who never stopped loving the person he lost. In 1946, 16 months after his wife and childhood sweetheart Arline died from tuberculosis at just 25, Richard Feynman wrote her a deeply personal letter that he never mailed. He ended it by saying he couldn't send it because he didn't know her new address. Years later, Feynman would go on to share the 1965 Nobel Prize in Physics. 📸: LaBeouf, Rönkkö & Turner / NewHive #physics #loveletter #science
