[net.physics] Correction: jow much mercury in a light bulb?

DIETZ@RUTGERS.ARPA (10/31/84)

A torr is a mm of mercury, not an atmosphere, so there's only about
110 micrograms of mercury in a bulb, not 90 milligrams.  With that much
you can afford really inefficient separation techniques and still make
a profit.
