| Popis: | Femto 17(1), (2017). The whirring flight of hummingbirds is legendary. It propels them through the air with 50 wingbeats per second, faster than the human eye can see. But even the fastest wingbeats by far in the world of birds look sluggish compared to the temporal dimensions that are currently being investigated in the field of ultrafast physics. Thanks to sophisticated laser technologies, researchers are able to make snapshots on the scale of femtoseconds and attoseconds ��� incredibly short time intervals, some of which last less than 0.000 000 000 000 001 seconds, i.e. a millionth of a billionth of a second. It���s on these time scales that the fundamental processes of matter are taking place. Published by Deutsches Elektronen-Synchrotron, DESY, Hamburg |
