Electronics is the field of manipulating electrical currents and voltages using passive and active components that are connected together to create circuits. Electronic circuits range from a simple load resistor that converts a current to a voltage, to computer central-processing units (CPUs) that can contain more than a million transistors. The following indices and documents provide a basic reference for understanding electronic components, circuits, and applications.
Wow, what wonders will the Twentieth Century bring? We might even soon have radios, television and home computers!
Don't knock it. You could write one of these things about metalworking, and we'd be ready for the 19th century.
"Metalworking is the field of manipulating metal into desired shapes by means of heat, force, and shearing, using mostly active components that are connected together to create tools and machines. Metalworking tools range from simple chisels and hammers that shear off pieces of metal, to..."
"The following indices and documents provide a basic reference for understanding metalworking tools, machines, and applications. You, too, can build a wood stove and outhouse using nothing but ores you can pick up on a road trip and trees from your woodlot..."
