The early history of laser cooling is a tale of three Nobel Prizes, a lot of hard work and a soupcon of serendipity. https://physicsworld.com/a/cold-how-physicists-learned-to-manipulate-and-move-particles-with-laser-cooling/
As a former atomic physicist myself, it's been a real honour to edit @orzelc's three-part history of this field. Part 1 is available now, go read it! #physics #science
