Newton’s Dusty Mirror: Old experiment inspires ultrafast imaging

Occasionally, science museums can stimulate new science. Inspired by an exhibit on an optical experiment performed by Isaac Newton, physicists have taken the first X-ray snapshot of a microscopic explosion.

NEWTON REVISITED. An X-ray beam (yellow) passes through one mirror, blows up a microscopic particle suspended on a membrane (in green frame), bounces off a second mirror (right), and hits the exploding particle again.
