[++] "Lorenz introduced [in the paper offered here] the maximum simplification equations and demonstrated that they could be used to understand certain atmospheric phenomena, such as the index cycle. The dynamical equations were simplified to a point where reasonable predictions of atmospheric conditions could not be expected, however, certain physical processes and features of interest were retained.Lorenz [in this paper] was able to capture many of the qualitative features of the flow including the exchange of kinetic energy between the zonal and meridional components. Motivated by this success, the basic spirit of this ground-breaking work of [this work] namely approximating the solution of complex realistic problems using a low-order model (LOM) has become a standard arsenal in problem solving in geophysical domain."--"Further Analysis of Lorenz's Maximum Simplification Equations", S. Lakshmivarahan et al, Journal Atmospheric Sciences 1 November 2006. [++]The Keeling abstract: "A systematic variation with season and latitude in the concentration and isotopic abundance of atmospheric carbon dioxide has been found in the northern hemisphere. In Antarctica, however, a small but persistent increase in concentration has been found." .

Scarce set of original issues from 2nd through 4th years ofDr. Dobb's Journal,which was launched as a quarterly xerographed newsletter by Bob Albrecht and Dennis Allison. The privately circulated publication was so popular, the magazine launched the following year with Jim Warren as its editor, and as the first ongoing periodical devoted entirely to software and programming. This set includes 8 issues from Volume 2 (lacking issues 4 and 7), along with complete runs of 10 issues of Volumes 3 and 4. At least one of these issues has articles by Steve Wozniak at Apple. Each of the early volumes were published the year following in collected volumes, but original issues from the first few years remain scarce. . 28 staple bound issues in printed self wrappers, generally 50-60pp in length. Few illustrations, ads, publisher's renewal cards, etc. Some toning to pages, mostly in Volume 4. Few bent corners, edge wear. Generally very good.

Nice press photo of this dual, redundant computer system developed by Moore Systems, Inc. of San Jose. The photograph shows the system in use for directing hydroelectric processes at the Bureau of Reclamation Energy Control Center in Casper, WY. 8x10" black and white photograph, captioned in 5 lines of text below. Light edge wear, nearly fine.

Vintage Bakelite prototype model hard disk pack, created circa 1967. Small printed label of Caelus Memories Incorporated adhered to the bottom of the canister, with a small engraving on the bottom crediting manufacturer Jupitor [sic] Corporation in Japan. Caelus was a start-up created around 1966, of note initially as an early supplier of "IBM clone" (IBM compatible) disk packs. The disks, also known as platters, were typically supplied with a protective canister featuring a lifting handle, as shown here. The model, a miniature representation of the 14-inch hard disks used by IBM, was likely created for a trade show. Approximately six inches in diameter. Near Fine.

Department of the Air Force and related publications on guided missiles issued between 1958 and 1959 document the technical, strategic, and institutional development of missile systems during the Cold War arms race, including coordination between U.S. military training programs and NATO aligned industrial production. Produced for both instructional and public facing contexts, these works establish missile technology as a central component of military doctrine, combining engineering principles with battlefield application and geopolitical strategy. The archive supports research into Cold War science, aerospace engineering, military training, and the integration of civilian industry within defense systems. Department of the Air Force. Guided Missiles Fundamentals (AFM 52-31). Washington, D.C.: Department of the Air Force, 1958; Department of the Air Force, U.S. Air Reserve. General Training: Missiles (SSM). Maxwell Air Force Base, AL: Air University, 1959; Missiles and Rockets. New York: American Aviation Publications, June 15, 1959 issue. Three volumes totaling 575, 28, and 58 pages respectively, illustrated with diagrams and black and white photographs, in original vinyl and paper wraps. The General Training booklet defines surface to surface missiles as ranging from "a small solid propellant antitank bazooka weapon. to intercontinental ballistic missiles. capable of reaching targets 3,000 to 5,000 miles away," and traces the origins of rocketry from ancient China through twentieth century experimentation, noting that missile development advanced under figures including Wernher von Braun. Systems discussed include Redstone, Jupiter, and Atlas missiles. The Missiles and Rockets issue features coverage of Nike Hercules missile deployments in Taiwan, NATO systems such as the British Bloodhound missile, and articles linking telecommunications automation to missile guidance and radar systems. Guided Missiles Fundamentals provides detailed classifications of guidance systems as active, passive, and preset, with diagrams illustrating control components, trajectory systems, and electronic coordination, including descriptions of guidance processes operating at "microsecond intervals." These publications were produced at a time when missile systems and space technology were rapidly advancing in response to geopolitical competition with the Soviet Union, and they reflect the integration of scientific research, military training, and industrial production within Cold War defense infrastructure. The materials demonstrate how technical knowledge was standardized and disseminated across military personnel while also being communicated to broader audiences through trade publications that linked defense innovation to industry. The emphasis on guidance systems, propulsion, and deployment strategies illustrates the centrality of missile technology in deterrence and warfare planning during this period. Bindings secure with interiors clean; minor chipping to wraps of Missiles and Rockets and light rust to staples of the training booklet; overall very good condition.

First Edition. United States Air Force. Guided Missiles Fundamentals. 1957. This manual presents the technical framework used by the U.S. Air Force to train personnel in guided missile systems during the early Cold War, when missile development became central to military strategy and nuclear delivery capability. The text outlines the principles of missile guidance, control, and accuracy, including the classification of guidance systems and the role of onboard computation, situating the material within the rapid expansion of aerospace engineering and electronic control technologies in the 1950s. It provides direct evidence of how the Air Force standardized knowledge of missile operation at a time when guided weapons were reshaping military doctrine. United States Air Force. Guided Missiles Fundamentals (AFM 52-31). Washington: Department of the Air Force, 20 September 1957. First edition. The manual includes sections such as "Components of Guided Missile Guidance Systems" and "Computer Units of Guidance Systems," describing the integration of sensor units, reference systems, and computational processes required to maintain flight paths. Diagrams illustrate beam-rider guidance, celestial navigation, and electronic control systems, including a "Basic missile guidance block diagram" showing how course corrections are made at "microsecond intervals." The text explains three principal types of guidance systems-active, passive, and preset-and distinguishes guided missiles from guided bombs by noting that missiles rely on onboard propulsion while bombs depend on aircraft velocity and altitude. A representative passage states, "Any guidance system must employ certain components; that is, there must be an adequate number of stages in the system to accomplish the guidance function," emphasizing the layered structure of control systems. Issued during a period of accelerated weapons development following World War II, the manual reflects the integration of electronics, computation, and aeronautics that defined Cold War military research and training. Manuals such as this were used to instruct personnel in emerging technologies that supported both conventional and nuclear capabilities. 575 pages; illustrated with technical diagrams; original vinyl covers. Mild chipping to covers and spine; binding tight; interior clean and bright; overall very good. A detailed instructional document of early guided missile systems, preserving the technical language and training standards of Cold War aerospace engineering.
