A team from Ludwig-Maximilians-Universität (LMU) and Max Planck Institute of Quantum Optics (MPQ) has now managed to shorten electron pulses down to 28 femtoseconds in duration. One femtosecond is a millionth of a billionth of a second. Such shutter speeds enable us to directly observe the truly fundamental motions of atoms and molecules in solids, similar to stroboscopy.
