In May of 1888, Tesla delivered his lecture "A New System of Alternating Current Motors and Transformers" be...

Henry Fords design of the Model T automobile between 1906 and 1908 was an extraordinary achievement. The industry was, at the time, still in an experimental phase and yet this design lasted without major change for nearly two decades.
