Homemade Microgram Electrobalance. By Shawn Carlson, Scientific American, June 1996 Microgram balances are clever devices that can measure fantastically tiny masses.
Top-of-the-line models employ an ingenious combination of mechanical isolation, thermal insulation and electronic wizardry to produce repeatable measurements down to one tenth of a millionth of one gram.

New models can cost more than $10,000 and often require a master's touch to coax reliable data from background noise. But for all their cost and outward complexity, these devices are in essence quite simple. And that is good news for amateurs. George Schmermund of Vista, Calif., made this fact clear to me.

Suddenly, you may have no choice but to barter for what you need. How often will the guy with goat you want, need the generator you have to trade? And how will you buy small items, like a dozen eggs, or a pail of milk, without a good substitute for currency? Silver and gold may step in and function as a true replacement currency.
