VON NEUMANN, JOHANN (JOHN). - THE MATHEMATICAL FOUNDATION OF QUANTUM MECHANICSBiblio.com

192847068Berlin Weidmannsche Buchhandlung 1928. 8vo. Full cloth but spine gone. In: "Nachrichten von der Gesellschaft der Wissenschaften zu Göttingen aus dem Jahre 1927". 4469 pp. Von Neumann's papers: pp. 1-57 pp. 245-272 a. pp. 273-291. Internally clean and fine. 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. hardcover

SCHRODINGER, ERWIN - FIRST TREATMENT OF WAVE MECHANICS IN ENGLISHBiblio.com

An undulatory Theory of the Mechanics of Atoms and Molecules.

192647172Minneapolis Minn. The Physicalreview 1926. 4to. Contemp. full buckram. Small tear to first hinge at foot. A stamp in upper right corner on titlepage and 2 other pages. In: "The Physical Review. Conducted by the American Physical Society" Vol. 28 Second Series. VI1343 pp. Entire volume offered.Schrödinger's paper: pp. 1049-1070. Internally clean and fine. First appearance of the first treatment of Wave Mechanics in English.The paper reviews Schrödinger's own wave-mechanics and De Broglie's "phase waves" and covers all the results Schrödinger had hitherto obtained in his main communications of 1926 the 3 papers in German. An English translation of Schrödinger's main papers was not published until 1928."The paper gives an account of the author's work on a new form of quantum theory. §1. The Hamiltonian analogy between mechanics and optics. §2. The analogy is to be extended to include real "physical" or "undulatory" mechanics instead of mere geometrical mechanics. §3. The significance of wave-length; macro-mechanical and micro-mechanical problems. §4. The wave-equation and its application to the hydrogen atom. §5. The intrinsic reason for the appearance of discrete characteristic frequencies. §6. Other problems; intensity of emitted light. §7. The wave-equation derived from a Hamiltonian variation-principle; generalization to an arbitrary conservative system. §8. The wave-function physically means and determines a continuous distribution of electricity in space the fluctuations of which determine the radiation by the laws of ordinary electrodynamics. §9. Non-conservative systems. Theory of dispersion and scattering and of the "transitions" between the "stationary states." §10. The question of relativity and the action of a magnetic field. Incompleteness of that part of the theory." From the Abstract in front of the paper. hardcover

Providence Association of Mechanics and ManufacturersBiblio.com

To the City Council of the City of Providence. Manuscript petition to the Providence City Council concerning public schools

57701Providence: January 30 1837. 4to approx. 10" x 8 5 leaves of ruled stationery with manuscript in ink on rectos only in a neat secretarial hand bound with blue silk ribbon; previous folds very light staining otherwise near fine. Interesting chapter in the historical evolution of the Providence school system. The Providence Association of Mechanics and Manufacturers was politically involved in city affairs as early as 1799 when "the want of a better system of school instruction being deeply felt by the members a memorial was prepared and presented to the General Assembly urging the establishment of free schools throughout the State and reminding that body that liberty and security under a republican form of government depend on a general diffusion of knowledge amoug the people" A History of Public Education in Rhode Island: from 1636 to 1876 byThomas B. Stockwell 1876 In 1837 the association under President George Baker and Samuel Tingley Jr. Secretary whose names appear on page four presented the petition: "Your memorialists have been struck with one fact . that the instruction of youth in the public schools is a heavy tax upon the middling classes without an adequate return as they do not participate in the benefit of this public instruction. This argument which is evidently weighty in the present condition of these schools would be destroyed if they were raised to the condition desired by your memorialists. "Why is it that the middling classes do not become participants in this instruction There is evidently but one reason. They perceive that the crowded state of the schools alone would prevent proper attention to the pupil; and they are aware that with the small sum which the instructors receive it is difficult to procure and retain the services of competent persons to fill the station. But let the schools be made so numerous that the scholars may receive as much attention as they do in the private schools and let the salaries be so large as to induce men of equal ability to take charge of them and that which is now considered as a tax would then be viewed as an alleviation of one of the heaviest burdens put upon the middling classes. "Your honorable body have no doubt . perceived how far we are behind our neighboring cities in this particular. Whilst they are constantly aiming at perfection in their free school system we have been at a stand or retrograding . To remedy the defect in our present system your memorialists would suggest that a grade of schools be established between the primary and writing schools for reading writing and arithmetic only the design of which is to give a thorough instruction in these branches to those children whose parents need their services at as early an age as twelve or thirteen years and who under the present arrangement are compelled to leave school with a very superficial knowledge of those branches which are so necessary for obtaining a livelihood in any business . To effect an essential reform in our public school system great expense must necessarily be incurred; and your memorialists who represent a large portion of the heads of families of the city would meet this increased expense with hearty encouragement." The document is signed "George Baker President. Samuel Tingley Jr. Secretary." Page 5 is entitled "Resolutions" and includes a list of seven statements relative to the Association's petition beginning with "Resolved that no subject can be of more importance to the inhabitants of this city than the education of the rising generation" and that "the members of this association were the pioneers in the establishment of the Public Schools." "This petition or memorial was referred to a committee who subsequently reported a plan for the improvement of the schools; but the provisions of it were deemed unsatisfactory. A second plan was presented comprising twelve primary eight intermediate and four upper schools. With these modifications the bill was returned to the common council who refused to concur. After frequent meetings and protracted debates with no unity the board of aldermen devised a plan embracing ten primary schools six intermediate schools two upper schools and two schools for colored children. This when presented to the common council was voted down by a large majority and without any final decision the municipal year closed. The feeling on the school question was now stronger than ever" Stockwell. January 30, 1837 unknown

Applied Physics Mechanics Thermodynamics Fluid Mechanics and Engineering Handwritten and Finely Illustrated Notebooks1878-9

1878215461878. EngineeringPhysics Three manuscript volumes 1878-1879 compiled in Germany notes on nineteenth-century study of applied physics mechanics thermodynamics and fluid engineering at a moment when the German states were consolidating their position as leaders in industrial science and technical education. Produced during the height of Imperial Germany's expansion of polytechnic institutes and research universities these notebooks reflect the rigorous mathematical formalism and applied design training that undergirded the nation's rapid industrialization. The systematic integration of theoretical mechanics with detailed machine drawings situates the work within the educational culture that supported advances in steam power turbine development and precision engineering in the decades following unification in 1871. As working instructional volumes they provide primary evidence of how Newtonian mechanics thermodynamic principles and mechanical design were taught to engineers in the late nineteenth century. Three handwritten volumes titled "I. Band" "II. Band" and continuation volume. Germany 1878-1879. The first volume opens with "Allgemeine Mechanik" outlining foundational principles including "Zusammensetzung und Zerlegung der Kräfte" and a carefully drafted "Parallelogramm der Kräfte" accompanied by geometric constructions and vector decompositions central to applied statics. Subsequent sections demonstrate lever calculations and force polygons rendered with precision technical drafting. The second volume advances into applied mechanics addressing "elastische Körper" rotational dynamics and "Zentripetalkraft" with formula derivations and diagrams of circular motion. Detailed gear assemblies and meshing systems indicate practical engagement with machine design while a section devoted to "Schmidt'scher Wassermotor" includes a sectional rendering of a turbine mechanism. The third volume transitions to thermodynamic systems including extended treatment of heat exchangers "Caloriferes" and a large fold-out "Schieberdiagramm für variable Expansion" attributed to G. Huber illustrating valve timing in steam engines through radial plotting. A further fold-out cross-section of a high-pressure steam engine demonstrates piston-cylinder interaction and valve actuation accompanied by efficiency calculations and pressure analyses. The presence of fold-out engineering plates systematic red and black ink notation and sequential theoretical development strongly suggests production within a university or technical institute environment. Three volumes. Extensive manuscript text with numerous diagrams and multiple fold-out plates. Original marbled paper boards with manuscript title labels. Bindings intact; minor hinge wear; spine cracking on one volume; pages clean and bright; fold-outs crisp with slight fraying at some edges. Overall very good. As a comprehensive and internally coherent set of engineering study notebooks from the period when German technical education shaped global industrial practice these volumes offer substantive insight into the pedagogical transmission of classical mechanics and steam engineering at a formative moment in modern industrial history. unknown
