"I got 20 flashlight batteries and lots of wire and bulbs and some kind of doorbell mechanism, so that was fun. Then I found that if you didn’t use the light bulb in the circuit but only the wire, it becomes red hot. That was pretty nice, because the insulation was burned by that [...] that led me to research on other things, such as black powder, which my father helped to buy the components for. By the time I was in eighth grade I was a researcher for minor explosives, so I feel right at home in the Nobel company."
- John Hall on how his scientific career started at an early age.
Hall, together with his co-laureate Theodor Hänsch, developed the frequency comb technique, in which laser light with a series of equidistant frequencies is used to measure frequencies with great precision.
