Simulating Physics with Computers
International Journal of Theoretical Physics, VoL 21, Nos. 6/7, 1982 Simulating Physics with Computers Richard P. Feynman Department of Physics, California Institute of Technology, Pasadena, California 91107 Received May 7, 1981 1. INTRODUCTION On the program it says this is a keynote speech--and I don't know what a keynote speech is. I do not intend in any way to suggest what should be in this meeting as a keynote of the subjects or anything like that. I have my own things to say and to talk about and there's no implication that anybody needs to talk about the same thing or anything like it. So what I want to talk about is what Mike Dertouzos suggested that nobody would talk about. I want to talk about the problem of simulating physics with computers and I mean that in a specific way which I am going to explain. The reason for doing this is something that I learned about from Ed Fredkin, and my entire interest in the subject has been inspired by him. It has to do with learning something about the possibilities of computers, and also something about possibilities in physics. If we suppose that we know all the physical laws perfectly, of course we don't have to pay any attention to computers. It's interesting anyway to entertain oneself with the idea that we've got something to learn about physical laws; and if I take a relaxed view here (after all I'm here and not at home) I'll admit that we don't understand everything. -
Analytical Engine, 1838 ALLAN G
Charles Babbage’s Analytical Engine, 1838 ALLAN G. BROMLEY Charles Babbage commenced work on the design of the Analytical Engine in 1834 following the collapse of the project to build the Difference Engine. His ideas evolved rapidly, and by 1838 most of the important concepts used in his later designs were established. This paper introduces the design of the Analytical Engine as it stood in early 1838, concentrating on the overall functional organization of the mill (or central processing portion) and the methods generally used for the basic arithmetic operations of multiplication, division, and signed addition. The paper describes the working of the mechanisms that Babbage devised for storing, transferring, and adding numbers and how they were organized together by the “microprogrammed” control system; the paper also introduces the facilities provided for user- level programming. The intention of the paper is to show that an automatic computing machine could be built using mechanical devices, and that Babbage’s designs provide both an effective set of basic mechanisms and a workable organization of a complete machine. Categories and Subject Descriptors: K.2 [History of Computing]- C. Babbage, hardware, software General Terms: Design Additional Key Words and Phrases: Analytical Engine 1. Introduction 1838.

William Gibson Fonds
William Gibson fonds Compiled by Christopher Hives (1993) University of British Columbia Archives Table of Contents Fonds Description o Title / Dates of Creation / Physical Description o Biographical Sketch o Scope and Content o Notes File List Catalogue entry (UBC Library catalogue) Fonds Description William Gibson fonds. - 1983-1993. 65 cm of textual materials Biographical Sketch William Gibson is generally recognized as the most important science fiction writer to emerge in the 1980s. His first novel, Neuromancer, is the first novel ever to win the Hugo, Nebula and Philip K. Dick awards. Neuromancer, which has been considered to be one of the influential science fiction novels written in the last twenty-five years, inspired a whole new genre in science fiction writing referred to as "cyberpunk". Gibson was born in 1948 in Conway, South Carolina. He moved to Toronto in the late 1960s and then to Vancouver in the early 1970s. Gibson studied English at the University of British Columbia. He began writing science fiction short stories while at UBC. In 1979 Gibson wrote "Johnny Mnemonic" which was published in Omni magazine. An editor at Ace books encouraged him to try writing a novel. This novel would become Neuromancer which was published in 1984. After Neuromancer, Gibson wrote Count Zero (1986), Mona Lisa Overdrive (1988), and Virtual Light (1993). He collaborated with Bruce Sterling in writing The Difference Engine (1990). Gibson has also published numerous short stories, many of which appeared in a collection of his work, Burning Chrome (1986). Scope and Content Fonds consists of typescript manuscripts and copy-edited, galley or page proof versions of all five of Gibson's novels (to 1993) as well as several short stories. -

Mirrorshade Women: Feminism and Cyberpunk
Mirrorshade Women: Feminism and Cyberpunk at the Turn of the Twenty-first Century Carlen Lavigne McGill University, Montréal Department of Art History and Communication Studies February 2008 A thesis submitted to McGill University in partial fulfilment of the requirements of the degree of Doctor of Philosophy in Communication Studies © Carlen Lavigne 2008 2 Abstract This study analyzes works of cyberpunk literature written between 1981 and 2005, and positions women’s cyberpunk as part of a larger cultural discussion of feminist issues. It traces the origins of the genre, reviews critical reactions, and subsequently outlines the ways in which women’s cyberpunk altered genre conventions in order to advance specifically feminist points of view. Novels are examined within their historical contexts; their content is compared to broader trends and controversies within contemporary feminism, and their themes are revealed to be visible reflections of feminist discourse at the end of the twentieth century. The study will ultimately make a case for the treatment of feminist cyberpunk as a unique vehicle for the examination of contemporary women’s issues, and for the analysis of feminist science fiction as a complex source of political ideas. Cette étude fait l’analyse d’ouvrages de littérature cyberpunk écrits entre 1981 et 2005, et situe la littérature féminine cyberpunk dans le contexte d’une discussion culturelle plus vaste des questions féministes. Elle établit les origines du genre, analyse les réactions culturelles et, par la suite, donne un aperçu des différentes manières dont la littérature féminine cyberpunk a transformé les usages du genre afin de promouvoir en particulier le point de vue féministe. -
Analytical Engine: the Orig- Inal Computer
Chapter 2 Analytical Engine: The Orig- inal Computer As we learned in the fourth grade science course, back in 1801, a French man, Joseph Marie Jacquard, invented a power loom that could weave textiles, which had been done for a long time by hand. More interestingly, this machine can weave tex- tiles with patterns such as brocade, damask, and matelasse by controlling the operation with punched wooden cards, held together in a long row by rope. 1 How do these cards work? Each wooden card comes with punched holes, each row of which corresponds to one row of the design. In each position, if the needle needs to go through, there is a hole; other- wise, there is no hole. Multiple rows of holes are punched on each card and all the cards that compose the design of the textile are hooked together in order. 2 What do we get? With the control of such cards, needs go back and forth, moving from left to the right, row by row, and come up with something like the following: Although the punched card concept was based on some even earlier invention by Basile Bou- chon around 1725, “the Jacquard loom was the first machine to use punch cards to con- trol a sequence of operations”. Let’s check out a little demo as how Jacquard’s machine worked. 3 Why do we talk about a loom? With Jacquard loom, if you want to switch to a different pattern, you simply change the punched cards. By the same token, with a modern computer, if you want it to run a different application, you simply load it with a different program, which used to keep on a deck of paper based punched cards. -
History of Computing Prehistory – the World Before 1946
Social and Professional Issues in IT Prehistory - the world before 1946 History of Computing Prehistory – the world before 1946 The word “Computing” Originally, the word computing was synonymous with counting and calculating, and a computer was a person who computes. Since the advent of the electronic computer, it has come to also mean the operation and usage of these machines, the electrical processes carried out within the computer hardware itself, and the theoretical concepts governing them. Prehistory: Computing related events 750 BC - 1799 A.D. 750 B.C. The abacus was first used by the Babylonians as an aid to simple arithmetic at sometime around this date. 1492 Leonardo da Vinci produced drawings of a device consisting of interlocking cog wheels which could be interpreted as a mechanical calculator capable of addition and subtraction. A working model inspired by this plan was built in 1968 but it remains controversial whether Leonardo really had a calculator in mind 1588 Logarithms are discovered by Joost Buerghi 1614 Scotsman John Napier invents an ingenious system of moveable rods (referred to as Napier's Rods or Napier's bones). These were based on logarithms and allowed the operator to multiply, divide and calculate square and cube roots by moving the rods around and placing them in specially constructed boards. 1622 William Oughtred developed slide rules based on John Napier's logarithms 1623 Wilhelm Schickard of Tübingen, Württemberg (now in Germany), built the first discrete automatic calculator, and thus essentially started the computer era. His device was called the "Calculating Clock". This mechanical machine was capable of adding and subtracting up to 6 digit numbers, and warned of an overflow by ringing a bell. -

The 3.2 kilogram InflateSail is “3U” in size and is equipped with a 1 metre long inflatable boom and a 10 square metre deployable drag sail. InflateSail's primary goal is to demonstrate the effectiveness of using a drag sail in Low Earth Orbit (LEO) to dramatically increase the rate at which satellites lose altitude and re-enter the Earth's atmosphere. InflateSail was launched on Friday 23rd June 2017 into a 505km Sun-synchronous orbit. Shortly after the satellite was inserted into its orbit, the satellite booted up and automatically started its successful deployment sequence and quickly started its decent. The spacecraft exhibited varying dynamic modes, capturing in-situ attitude data throughout the mission lifetime. -
