"I liked quantum mechanics very much. The subject was hard to understand but easy to apply to a large number of interesting problems."
"In fact, there really is not a new law of nature. It was all in the theory to begin with but nobody worked it out."

Willis Eugene Lamb Jr. was an American physicist who was able to precisely determine a surprising shift in electron energies in a hydrogen atom, known as the Lamb shift. For this work, Lamb shared the 1955 Nobel Prize in Physics with Polykarp Kusch. He was a professor at the University of Arizona College of Optical Sciences.

"Neither Dirac nor von Neumann discussed his measurements in physical terms."
"In his 1930 book, Dirac took for granted that measurements could be made, but was very vague about what was actually involved."
"A rare theorist turned experimentalist."
"At the first of the 1960s Rochester Coherence Conferences, I suggested that a license be required for use of the word photon, and offered to give such license to properly qualified people."
"A gifted experimentalist, and theoretician, in the best Newtonian tradition... His contributions to quantum measurements, and elucidative teachings on quantum mechanics, have not yet received the attention they deserve."
