Discoveries in the physical sciences have a long history of fueling innovation. They often lead to new devices and new inventions that even the discoverers could not have imagined.

Working with the Emilio Segrè Visual Archives at the American Center for Physics in College Park, Maryland, we dug up images from classic physics experiments conducted over the last two centuries. We also found some swell pics of technological advances ranging from police radar guns to space telescopes.

Can you match each experiment to the innovations it made possible?
