The taxonomy of materials,which at first contained the two general classes, magnetic and non-magnetic, began to assume more detail in the 1700's. We have seen that Gray's discovery of electrical conduction led to the division of non-magnetic materials into two types, conductors examples of ea...
When a magazine for high school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotateso they could follow the sun to take maximum advantage of its light and heat. Walls
