@mcnees
A "standard candle" is actually an older term -- it was a recipe for a light source of fixed intensity. (And, in fact, an actual candle, made from whale fat)

@level98 @mcnees yeah. But the term itself was not “coined” by her. (And the whales part is a cool story)

@mcnees I sometimes do a thing in class "Put up your hand if you have a relative who was alive in 1923, 1929, 1965..." -- that person was born before... But the 1923 one has got a bit harder :-)
