Corona discharge with a discharge current of a few hundred microamperes can blow out a small candle flame within about 1 cm of a discharge point. A pinwheel, with radial metal spokes and pointed tips bent to point along the circumference of a circle, can be made to rotate if energized by a corona discharge; the rotation is due to differential electric attraction between the metal spokes and the space charge shield region that surrounds the tips. Corona discharge A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is
Word and Object behavior from the native and the visible environment the native interacts with. The same view is displayed in chapter 3 where Quine describes how a baby learns its first words. In this chapter Quine also mentions B.F. Skinner, a well known behaviorist, as one of his influences. In the second chapter of "Word and Object", Quine investigates the concept of meaning. He shows to what extent his own, empirical, notion of meaning can give an account for our intuitive concept of meaning: 'what a sentence shares with its translation'. Quine also introduces his famous principle of "indeterminacy of translation", with
