Instead, a nanoscientist could use a scanning tunneling microscope or an atomic pressure microscope. Scanning tunneling microscopes use a weak electric current to probe the scanned material. Both microscopes send information to a computer, which assembles the data and projects it graphically onto a monitor. Atomic force microscopes scan surfaces with an incredibly advantageous tip. The one blemish on his report was an eight-spherical draw with Lloyd Christie in 1982. Although Marsh had a fine a...
