I understand (at an undergrad level) superimposing light waves. But this blows my mind:

At the same time, Ferenc Krausz and his research group in Austria were working on a technique that could select a single pulse – like a carriage being uncoupled from a train and switched to another track. The pulse they succeeded in isolating lasted 650 attoseconds

Understanding it at a high-level certainly doesn’t take away from the achievement one bit. You still have to be incredibly precise and know the techniques inside and out. Obviously everyone agrees since they received a Nobel Prize.
