Precision is the heart of science.
Theories open new vistas, and many experiments give qualitative answers.
Yet those who measure precisely give life to all that we call science. Albert Michelson was the Great Measurer. In 1854, two years after Albert was born, the Michelson's emigrated from their home in Poland to New York City and then to California. They settled among the miners in Murphy's Camp and then followed the silver rush to Virginia City, Nevada. Albert's father supported the family with profits from his small dry goods store.
