The Electron's Motion


ScienceDaily (Feb. 25, 2008) With the use of a newly developed technology for generating short pulses from intense laser light, scientists in Sweden have managed to capture the electron's motion for the first time. (Credit: Image courtesy of Johan Mauritsson, Lund University)
"It takes about 150 attoseconds for an electron to circle the nucleus of an atom. An attosecond is 10-18 seconds long, or, expressed in another way: an attosecond is related to a second as a second is related to the age of the universe," says Johan Mauritsson, an assistant professor in atomic physics at the Faculty of Engineering, Lund University.

Ein Sof




Kabbalists speak of the first aspect of God as Ein Sof (אין סוף); this is translated as "the infinite", "endless", or "that which has no limits". In this view, nothing can be said about this aspect of God. This aspect of God is impersonal. The second aspect of divine emanations, however, is at least partially accessible to human thought.
