2nd Episode Memex RaiScuola:The technology to spy on the matter
Technologies to closely observe the atom and matter are many. The spectroscopy (atoms and molecules in motion), and the synchrotron light and pulsed electromagnetic radiation such as that produced in a free electron laser, allow to observe transient phenomena that take place inside of the molecules. These are phenomena which occur in very small time intervals, of the order of a millionth of a billionth of a second (femtosecond).
