Condolences to the family and friends of Professor Rubin. She's not a household name, but in her field she was a remarkable individual, all the more so because she was a woman in an overwhelmingly male-dominated discipline. She discovered observational data that was completely counter-intuitive to the prevailing scientific theories of her day. She took a lot of flak for that, likely amplified because of gender bias. But she stood by her work- which was probably the first known evidence of dark matter- and was vindicated.
