SCIENCE QUESTION: “ACCORDING TO THE PRINCIPLE OF RELATIVITY”
SIR ARTHUR SCHUSTER (1851-1934) HANDWRITTEN NOTE SIGNED, “Arthur Schuster”, on a card 4.5 x 3.5, 2 January 1923, St. Raphail, by the British physicist known for his work in spectroscopy, electrochemistry, optics, X-radiography, and the application of harmonic analysis to physics. Schuster’s integral is named after him and he is most widely remembered for his periodogram analysis. He is credited with coining the concept of antimatter and is regarded as a mathematical physicist. His handwritten note, in full: “What is the difference between a dog that wags its tail and a tail that wags the dog to which it is attached? According to the Principle of Relativity the answer is ‘None.’ In fact we often see what may correctly be described as an insignificant little tail not only wagging its dog but the entire world on which the dog stands.” In fine condition, with minor age toning.
