Nikola Tesla was an inventor and a mechanical and electrical engineer. He is best known for many revolutionary contributions in the field of electricity and magnetism in the late 19th and early 20th centuries. On his birthday last week Google dedicated a logo to honor his contribution to the world of science. In reading through the article they linked to I liked a quote from Tesla about Thomas Edison: “If Edison had to find a needle in a haystack, he would proceed with the diligence of a bee to examine straw after straw until he found [it]. I was a sorry witness to such doings … a little theory … would have saved him ninety percent of his labor”.
