Müsste Edison eine Nadel im Heuhaufen finden, würde er einer fleißigen Biene gleich Strohhalm um Strohhalm untersuchen, bis er das Gesuchte gefunden hat.
If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search. ... I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.
