"Melba Roy, NASA Mathmetician, at the Goddard Space Flight Center in Maryland in 1964. Ms. Roy led a group of NASA mathmeticians known as ""computers"" who tracked the Echo satellites. The first time I shared Ms. Roy on VBG, my friend Chanda Prescod-Weinstein, a former postdoc in astrophysics at NASA, helpfully explained what Ms. Roy did in the comment section. I am sharing Chanda's comment again here: ""By the way, since I am a physicist, I might as well explain a little bit about what"
