“If Edison needed to find a needle in a haystack, he would not stop to reason where the needle Nikola Teslamight be, but rather would examine every straw, straw after straw like a diligent bee until he found the object of his search. I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 percent of his labor.”

–Nikola Tesla
