> further shake engineering, or it is a waste of time. Between ~1870 and ~1950 we had a fireworks of discoveries.... ... which started with a simple observation. 200 years ago in 1820, Ørsted was giving a lecture when he noticed that a current-carrying wire deflects a compass needle. Of course, he had no idea what that would lead to, nor did anyone else. It was a completely 'pure', 'unuseable' observation. But, as a student of Kant (what a waste of time!) he shared it in a four-page pamphlet.
