That Obscure Object of Definition…

Via friend P deV, the “obscure unit of the week: Bohr magnetons per angstrom”…

In explaining their (pretty remarkable) findings that magnetism can, in some circumstances, behave like electricity— “magnetricity” if one will– scientists from the London Centre for Nanotechnology invoked evidence denominated in what has to one of the rarer metrics around:  Bohr magnetons per angstrom.

But worth understanding, as the observation suggests that it may be possible to create units of digital storage one magnetic monopole large– that’s to say, about the size of an atom.  As lead investigator Steven Bramwell said (with typical British understatement), “monopoles could one day be used as a much more compact form of memory than anything available today.”

See the New Scientist report here; and more on the discovery at Next Big Future, here.

As we practice our scales, we might recall that it was on this date in 1948 that the Nobel Prize in Literature was awarded to T.S. Eliot, who undermined the need for more storage when he observed that “the most important thing for poets to do is to write as little as possible.”
