A Mini-History of Computing

This book was produced by George K. Thiruvathukal for the American Institute of Physics to promote interest in the interdisciplinary publication, Computing in Science and Engineering. It accompanied a limited edition set of playing cards that is no longer available (except in PDF). This book features a set of 54 significant computers by era/category, including ancient calculating instruments, pre-electronic mechanical calculators and computers, electronic era computers, and modern computing (minicomputers, maniframes, personal computers, devices, and gaming consoles)

The ingenuity of common workmen: and the invention of the computer

Since World War II, state support for scientific research has been assumed crucial to technological and economic progress. Governments accordingly spent tremendous sums to that end. Nothing epitomizes the alleged fruits of that involvement better than the electronic digital computer. The first such computer has been widely reputed to be the ENIAC, financed by the U.S. Army for the war but finished afterwards. Vastly improved computers followed, initially paid for in good share by the Federal Government of the United States, but with the private sector then dominating, both in development and use, and computers are of major significance.;Despite the supposed success of public-supported science, evidence is that computers would have evolved much the same without it but at less expense. Indeed, the foundations of modern computer theory and technology were articulated before World War II, both as a tool of applied mathematics and for information processing, and the computer was itself on the cusp of reality. Contrary to popular understanding, the ENIAC actually represented a movement backwards and a dead end.;Rather, modern computation derived more directly, for example, from the prewar work of John Vincent Atanasoff and Clifford Berry, a physics professor and graduate student, respectively, at Iowa State College (now University) in Ames, Iowa. They built the Atanasoff Berry Computer (ABC), which, although special purpose and inexpensive, heralded the efficient and elegant design of modern computers. Moreover, while no one foresaw commercialization of computers based on the ungainly and costly ENIAC, the commercial possibilities of the ABC were immediately evident, although unrealized due to war. Evidence indicates, furthermore, that the private sector was willing and able to develop computers beyond the ABC and could have done so more effectively than government, to the most sophisticated machines.;A full and inclusive history of computers suggests that Adam Smith, the eighteenth century Scottish philosopher, had it right. He believed that minimal and aloof government best served society, and that the inherent genius of citizens was itself enough to ensure the general prosperity

Inverted spin polarization of Heusler alloys for new spintronic devices

A new magnetic logic overcomes the major limitations of field programmable gate arrays while having a 50% smaller unit cell than conventional designs utilizing magnetic tunnel junctions with one Heusler alloy electrode. These show positive and negative TMR values at different bias voltages at room temperature which generally adds an additional degree of freedom to all spintronic devices

Comparison of the most popular operating systems in terms of functionalities

The main purpose of research is comparison of the following modern operating systems: Windows 10, Windows 11, MacOS Catalina and Linux Ubuntu 20.04 LTS. An analysis was made in terms of functionalities and time needed to perform basic activities. The systems were selected on the basis on performed popularity analysis, by using StatCounter [1] statistic. To study each operating system it was necessary to create two test stands corresponding to the requirements of the systems. Conducted research were divided on two sections. In the first one, analysis of the possessed functionalities, assessment of the advancement and ease of using them was performed. In the second section, examination was carried out to compare the operating system in terms of the time of performing specific activities
