For Claude Cohen-Tannoudji · 2d ago
My junior year roommate had the Cohen-Tannoudji textbook propped open on her desk every single night that whole semester, two thick blue volumes, and she'd read bits out loud to me like it was poetry even though I was an art major and understood maybe none of it. She called it just 'the Cohen-Tannoudji,' like everyone did. 93 years old. That's a whole life spent explaining light to people.
