Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 B.C., when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.
Crystals, such as quartz, can be tapped for electricity using a piezoelectric (mechanical energy discharge) method. By securing the crystal and subjecting it to direct force with a permanent magnet, a detectable amount of electricity is released. This technology is used in .

A typical quartz is expected to drift about 1 PPM per °C. Even for a system that has been running for several days in a non-air-conditioned office, the correction value changed by more than 1 PPM within a week (See Figure 2 for a snapshot from that machine). It is possible that a change in supply voltage also changes the drift value of the quartz.
