Venice, Gabriel Giolito de' Ferrari, 1559. Folio. Uncut in later (?) blank limp boards. A tear to middleof spine. Upper margins with brownspots, decreasing towards end. Large printer's woodcut-device at titlepage, 6 woodcut vignettes, 6 large woodcut initials. (12),563 pp. Wide-margined and printed on good paper. Apart from browning to upper margins, a clean copy. There were printed 2 editions the same year, one in Venice (the item offered) and one in Pesaro.Cavalcanti (1503-62) was a Florentine scholar-diplomat who served the Republic (1527-30), went into exile (1537), and spent his remaining years working for the Este and Farnese families. He died in poverty in Padua . His works reflect his interest in politics and scholarship: an oration to the Florentine militia (1530), political memoranda, diplomatic letters, translations from Polybius, essays on classical political thought (1571), and an amazingly successful Retorica (ten editions from 1559 to1585). The last, a comprehensive compendium of classical rhetoric written in Italian with Italian examples, maintains that the function of rhetoric is civic and practical rather than literary.Adams C 1175 (but with the wrong year).

London, Baldwin, Cradock, and Joy, 1816 a. 1821. Bound in 2 uniform contemp. moiré boards. Light wear along edges and a fes smaller scratches.

VIII,479 pp. a. 9 engraved plates, VIII,479 pp. a. 7 engraved plates. (Entire volumes offered). Herapath's papers: pp. 56-60 (1816) a. pp. 273-293, 340-351 a. 401-416. First printing of these contoversial papers where Herapath revived the kinetic theory of gases. His theory was more or less neglected by the scientific community at his time. The kinetic theory remained dormant and forgotten after Euler's and Bernouilli's work "until 1816, when Herapath proposed a theory which is essential Bernoulli's. Unfortunately he chose to define temperature as being proportional to the momentum rather than the kinetic energy of molecules. Herapath was the first to show, more or less, that kinetic theory can provide simple explanations for the changes of state, diffusion, and the propagation of sound."(Trousdell "Essayas in the History of Mechanics", pp. 283 ff.).Euler, Bernoulli, Herapath and Waterston may be considered the principal scientists who prior to 1850 attempted a more or less complete mathematical treatment of gases, based on a set of molecular postulates. (Jamie Wisniak)."Having published a preliminary notice of his theory in the Annals of Philosophy in 1816, Herapath submitted a detailed account to the Royal Society in 1820. Davy, who was elected to the presidency of the Society in November of that year, was primarily responsible for the fate of the paper. Although Davy was already known as an advocate of the qualitative idea that heat is molecular motion, he found Herapath’s quantitative development too speculative and complicated; he rejected the hypothesis of an absolute temperature implying an "absolute zero" of cold. Having been told that his paper would not be accepted for publication in the Philosophical Transactions, Herapath withdrew it and published it instead in the Annals of Philosophy in 1821. Five years later he launched an attack on Davy in the Times of London, accusing him of circulating unfounded criticisms of his experimental work, which prevented its publication. Although Davy ignored a series of letters and challenges published in the Times, Herapath later claimed Davy’s resignation from the presidency of the Royal Society (1827) as a victory for himself."(DSB).

First printing of von Neumann's importent papers in which he gave a mathematically precise formulation of the foundation of Quantum MeChanics, basing the theory on the use of Hilbert spaces."He (von Neumann) developed between 1927 and 1929 a new mathematical framework of the theory subsequently proved to be the most suitable formalism of nonrelativistic quantum mechanics as we use it today, as well as of its extensions, the relativistic quantum mechanics of partcles and the quantum theory of fields."(Max Jammer "The Conceptual Development og Quantum Mechanics", pp.314-15"Von Neumann’s most famous work in theoretical physics is his axiomatization of quantum mechanics. When he began work in that field in 1927, the methods used by its founders were hard to formulate in precise mathematical terms; "operator" on "functions" were handled without much consideration of their domain or definition to their topological properties: and it was blithely assumed that such "operators," when self-adjoint, could always be "diagonalized" (as in th finite dimensional case), at the expense of introducing "Dirac functions" as "eigenvectors." Von Neumann showed that mathematical rigor could be restored by taking as basic axioms the assumptions that the states of a physical system were poinds of a Hilbert space and that the measurable quantities were Hermitian (generally unbounded) operators densely efined in that space. This formalism. the practical use of which became available after von Neumann had developed the spectral theory of unbounded Hermitian operators (1929), has survived subsequent developments of quantum mechanics and is still the basisi of non relativistic quantum theory; with the introduction of the theory of distributions, it has even become possible to interpret its results in a way similar to Dirac’s original intuition."(DSB).

Stamp to lower part of title-page. Upper front hindge with 3 cm long tear. otherwise a fine copy. Pp. 433-58. [Entire volume: VIII, 876 pp. + 3 folded plates]. First appearance of the account of Lebedev's seminal experiment proving that light exerts a mechanical pressure on material bodies thereby confirming Maxwell's electromagnetic theory for the very first time - a landmark discovery in modern physics. James Clerk Maxwell "made an important new prediction from his electromagnetic theory-that electromagnetic waves exert a radiation pressure. Bright sunlight, he calculated, presses on the earth's surface with a force of around 4 pounds per square mile [...] This was too tiny a value to be observable in everyday life and its detection posed a challenge to experimenters. Eventually, in 1900, the Russian physicist Pyotr Lebedev succeeded, and confirmed James' prediction. Although small on an earthly scale, radiation pressure is one of the factors that shape the universe. Without it there would be no stars like our sun. [The] discovery also helped to explain a phenomenon that had puzzled astronomers for centuries-why comets' tails point away from the sun" (Mahan, The Man who Changed Everything: The Life of James Clerk Maxwell, 183)."As early as 1891 Lebedev became seriously interested in the pressure of light. He turned his attention to the fact that since the force of gravity is proportional to the volume of a body whereas light pressure must be proportional to its surface, it may be asserted that in a particle of cosmic dust the forces of light pressure pushing the particle away from the sun will be equals to the force of gravity attracting it toward the sun. Lebedev used this theory to explain why comets'tails always point away from the sun. His hypothesis was considered correct until the discovery of the solar wind, which creates substantially greater pressure than the sun's light.Around 1898, Lebedev began experimental research on light pressure. Although its presence had been predicted by Maxwell's theory, it had not been detected experimentally before Lebedev. He first undertook research on the pressure of light on solid bodies. Because of the weakness of the effect itself and the considerable number of possible side effects, this experimental problem presented very great difficulties: if a body that is supposed to react to light pressure is placed in a gas, the warming of the body by the light will inevitably cause convection currents and thus set the body in motion. If the body is placed in a vacuum (in practice, in gas at very low pressure), the so called radiometric effect will occur. As a result of the uneven warming of the front and back of the body, the molecules of gas hitting the body from the front will be repulsed more forcefully than those striking the back, thereby exerting greater pressure. By extremely ingenious methods Lebedev succeeded in completely eliminating these side effects and not only detected the pressure of light but also measured it and showed the correctness of Maxwell's quantitative theory. "Opytnoe issledovanie svetovogo davlenia"("An Experimental Investigation of the Pressure of Light") was read by Lebedev at the International Congress of Physicists at Paris in 1899 and was published in 1901."
