Today, scientists have created the world’s fastest 2D movie using a laser and particles! The movie captures the behavior of electrons as they move through a material in just a few thousandths of a trillionth of a second, making it the fastest ever recorded by a human-made device. The movie provides unprecedented insight into the behavior of electrons in materials, allowing scientists to better understand the basic science of materials and to develop new technologies.
