It's principle use to to create very high speed oscillators, in the microwave range. Some natural semiconductors also seem to have this capability, Cornish arsenopyrite and wolframite seem to occasionally. In a curve plot it looks like a reverse loop, it's hard to capture as it's ra...")

This was caused when the ancient continents of Euramerica and Gondwana collided to from the supercontinent of Pangaea. The granite that rose towards the surface under what is now Cornwall distilled many elements from deep in the earth into the existing ('country') rock in the margins around the granite. It was these areas that would very muc...")

This detector consists of two crystals--copper pyrites (Cu Fe S2) and zincite (zinc oxide ZnO), held in firm contact against each other in the manner shown. The copper pyrite crystal is mounted in a cup mounted on a spring-actuated rod provided with a suitable knob, by which it can be swung in any direction. Zincite crystals are mounted in a large cup containing...")
