Gilbert N. Lewis and Richard C. Tolman, The Principle of Relativity and Non-Newtonian Mechanics. In: the full volume of the London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science; London. Taylor & Francis, 1909. Vol. 18, Sixth Series, viii, 944 pp., 28 plates, with the Lewis/Tolman on pp 510-523. Beautifully rebound in half-morocco over marbled boards, with new endpapers and pastedowns, and with subtly-decorated dentelles with raised bands, and spine labels in red and black. The text is clean and bright, and the binding outstanding. [++] First appearance of this paper published outside the U.S.[++] "In 1909, Lewis and Tolman, then physical chemists at the Massachusetts Institute of Technology, wrote a paper which built on an earlier paper by Lewis. This gave a more mechanics based approach to the subject, in contrast to Einstein’s original work which drew on electrodynamics. This work played a significant role in the early development of special relativity theory, then only four years old and still under heated discussion worldwide. This paper with Tolman, though a relatively minor part of Lewis’s overall work, has historical and pedagogical value and gives a glimpse of his breadth, early growth and influence as a scientist."--"G N Lewis and Special Relativity. A Little Known Side of a Great Chemist" by Rajaram Nityananda in "Resonance", July 2019. [++]"The publication of Einstein’s theory of relativity (1905) and his mass-energy equation renewed Lewis’ interest in his early speculations on radiation. He derived the mass-energy equation from his early idea of the pressure of light without using the principle of relativity (1908). This striking concurrence of his view with Einstein’s convinced Lewis of the value of his youthful ideas and made him one of the very few early supporters of Einstein and relativity in America. A second paper with Richard Tolman (1912), deriving Einstein’s equation from conservation laws and the principle of relativity, illustrates Lewis’ delight in the bizarre paradoxes of relativity theory that most people found so profoundly disturbing: Lewis was an iconoclast and reveled in the overthrow of long-established ideas."--Complete DSB online (Lewis) [++] Relativistic Mass concept. "In the first years after 1905, following Lorentz and Einstein, the terms longitudinal and transverse mass were still in use. However, those expressions were replaced by the concept of relativistic mass, an expression which was first defined by Gilbert N. Lewis and Richard C. Tolman in 1909."--Wikipedia  (The first appearance of this paper was 1909, "The Principle of Relativity, and Non-Newtonian Mechanics," Proceedings of the American Academy of Arts and Sciences, 44 (25): 709–726.)
