Actor and writer Robert Shaw passed away #onthisday in 1978, just three years after his iconic performance as Quint in Steven Spielberg's #JAWS. He was just 51 years old.

Probably the best "slow fuse" paper I've discovered yet. This is the citation history for Fritz Zwicky's 1937 paper on the possibility of dark matter in the Coma cluster of galaxies. It really didn't get going until the '90s:

Amazing what you find in an astro department deep clear out. 30-year-old dot matrix printout of the Starlink kappa package bug fix anyone?
