formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps

by peeling apart a couple pieces of Scotch tape. Prior to that, obtaining the single atomic layer of
graphene had been quite difficult. Carbon nanotubes, stronger than steel and lighter than aluminum,
are the new wonder product being used in electronics, mechanics, and medicine. Toxicologists, however,
are concerned that they might also be the next asbestos since their similarity to asbestos in shape
makes it difficult for the lungs to remove once inhaled. Fortunately, we know to study the potential
dangers of nanotechnology during its development phase... not as a crisis response to devastatingly
