Niel Bohr said that before 1913 no one expected that the lines of color you get from burning hydrogen would tell you anything about physics even though the colors follow a pattern. Just like butterflies have patterns with the colors on their wings, “but nobody thought that one could get the basis of biology from …

How Tesla And Ferraris Invented The Two-Phase Motor

As I said in my video on the history of 3-phase electricity, both Nikola Tesla and Galileo Ferraris discovered two-phase electricity and the two-phase motor that were, according to Tesla, “identical almost to the smallest detail.” 1 So, how did these two men develop this fantastic discovery? Table of Contents Introduction How Ferraris Got Involved …
