A hundred years ago, Percy Bridgman invented mechanical devices that dramatically expanded the high-pressure range available for carrying out physics and chemistry experiments into an unprecedented regime of high densities. His pioneering work revolutionized condensed matter research. His spirit remains alive today as researchers continue to push back the boundaries of high-pressure science.
