The story of the word

The Intel 4004 shipped in 1971 carrying about 2,300 transistors, and the word arrived with the thing. μικρός is doing real work in the name, since what was new was not the processing but the scale: a room of equipment reduced to a fingernail. Its exact Greek opposite, μακρός, gives macro.
