Gordon Moore thought that continually improving technology would result in the number of transistors that could fit on a microchip doubling every eighteen months. What is a microchip?

Read these paragraphs from "There's Still Gold in Those Hills."
Unless a gold seeker spies a nugget in the pan (what luck!), he needs to add more water to the mix. He swishes the material in the pan in a slow, circular movement. The pan is tilted slightly so that the lightweight sand slips over the edge. Water is added as needed, and the process is repeated.
Soon, only a small part of the pan will be covered with concentrated material of what appears to be black sand. The swishing motion will spread the sand out in a feather pattern. The bits of material at the tail end of the feather are called tailings. This is where the gold bits can be found.
