How Did They Get to the Moon Without Powerpoint? How Did They Get to the Moon Without PowerPoint? Mordechai (Moti) Ben-Ari Department of Science Teaching Weizmann Institute of Science [email protected] Keynote speech at the Finnish Computer Science Society, May, 2003. 1 Developing a Technology The invention of writing, however, was the invention of an entirely new Let me start with a description of one of my first technology.[3, p. 9] full-time jobs: There is something to be said for this definition: I developed a technology for data min- do you remember those old movies that show “typ- ing in order to consolidate enterprise- ing pools,” where rows and rows of people, usually customer relations. women, sat pecking away at keyboards all day? Since I held that job in the early 1970s, clearly I would not have described my work in this terminol- ogy! What I actually did was: I wrote a program that read the system log, computed usage of CPU time and printed reports so that the users could be billed. My point in this talk is that hi-tech in general and computer science in particular did not begin in the 1990s, but that we have been doing it for decades. I believe that today’s students are being fed a lot of marketing propaganda to the contrary, and that they Well, things haven’t changed all that much! have completely lost a historical perspective of our discipline. I further believe that we have a respon- sibility as educators to downgrade the hype and to give our students a firm background in the scientific and engineering principles of computer science. The idea for this talk came to me while reading the hi-tech supplement that appears occasionally in a local newspaper. The supplement has a section in which they profile new startup companies, and invariably these companies “develop a technology,” though as far as I can understand from the short pro- files, they have simply designed and constructed a box of electronics or a computer program. So what is a “technology”? Here is one extreme view: I wouldn’t go so far as to claim that microchips Basically, microchips are merely a tech- are a mere “technical improvement,” but I certainly nical improvement over clay tablets. can’t accept that every new gadget or program is a 1 new technology.

  • I: the Conception
    Excerpt from: Mayo, Keenan and Newcomb, Peter. “How the Web Was Won,” Vanity Fair, July 2008. I: The Conception Paul Baran, an electrical engineer, conceived one of the Internet’s building blocks—packet switching— while working at the Rand Corporation around 1960. Packet switching breaks data into chunks, or “packets,” and lets each one take its own path to a destination, where they are re-assembled (rather than sending everything along the same path, as a traditional telephone circuit does). A similar idea was proposed independently in Britain by Donald Davies. Later in his career, Baran would pioneer the airport metal detector. Paul Baran: It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind. The problem was that we didn’t have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone- communication system. At that time the Strategic Air Command had just two forms of communication. One was the U.S. telephone system, or an overlay of that, and the other was high-frequency or shortwave radio. So that left us with the interesting situation of saying, Well, why do the communications fail when the bombs were aimed, not at the cities, but just at the strategic forces? And the answer was that the collateral damage was sufficient to knock out a telephone system that was highly centralized. Well, then, let’s not make it centralized. Let’s spread it out so that we can have other paths to get around the damage.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.

  • The Internet Development Process: Observations and Reflections
    The Internet Development Process: Observations and Reflections Pål Spilling University Graduate Center (UNIK), Kjeller, Norway [email protected] Abstract. Based on the experience of being part of the team that developed the internet, the author will look back and provide a history of the Norwegian participation. The author will attempt to answer a number of questions such as why was The Norwegian Defense Research Establishment (FFI) invited to participate in the development process, what did Norway contribute to in the project, and what did Norway benefit from its participation? Keywords: ARPANET, DARPA, Ethernet, Internet, PRNET. 1 A Short Historical Résumé The development of the internet went through two main phases. The first one laid the foundation for packet switching in a single network called ARPANET. The main idea behind the development of ARPANET was resource sharing [1]. At that time computers, software, and communication lines were very expensive, meaning that these resources had to be shared among as many users as possible. The development started at the end of 1968. The U.S. Defense Advanced Research Project Agency (DARPA) funded and directed it in a national project. It became operational in 1970; in a few years, it spanned the U.S. from west to east with one arm westward to Hawaii and one arm eastward to Kjeller, Norway, and then onwards to London. The next phase, the “internet project,” started in the latter half of 1974 [2]. The purpose of the project was to develop technologies to interconnect networks based on different communication principles, enabling end-to-end communications between computers connected to different networks.

  • List of Internet Pioneers
    List of Internet pioneers Instead of a single "inventor", the Internet was developed by many people over many years. The following are some Internet pioneers who contributed to its early development. These include early theoretical foundations, specifying original protocols, and expansion beyond a research tool to wide deployment. The pioneers Contents Claude Shannon The pioneers Claude Shannon Claude Shannon (1916–2001) called the "father of modern information Vannevar Bush theory", published "A Mathematical Theory of Communication" in J. C. R. Licklider 1948. His paper gave a formal way of studying communication channels. It established fundamental limits on the efficiency of Paul Baran communication over noisy channels, and presented the challenge of Donald Davies finding families of codes to achieve capacity.[1] Charles M. Herzfeld Bob Taylor Vannevar Bush Larry Roberts Leonard Kleinrock Vannevar Bush (1890–1974) helped to establish a partnership between Bob Kahn U.S. military, university research, and independent think tanks. He was Douglas Engelbart appointed Chairman of the National Defense Research Committee in Elizabeth Feinler 1940 by President Franklin D. Roosevelt, appointed Director of the Louis Pouzin Office of Scientific Research and Development in 1941, and from 1946 John Klensin to 1947, he served as chairman of the Joint Research and Development Vint Cerf Board. Out of this would come DARPA, which in turn would lead to the ARPANET Project.[2] His July 1945 Atlantic Monthly article "As We Yogen Dalal May Think" proposed Memex, a theoretical proto-hypertext computer Peter Kirstein system in which an individual compresses and stores all of their books, Steve Crocker records, and communications, which is then mechanized so that it may Jon Postel [3] be consulted with exceeding speed and flexibility.

  • Internet Technical Standardization: Low Public Visibility, High Public Policy Impact
    Internet Technical Standardization: Low public visibility, high public policy impact. Lecture Notes for a Guest Lecture in the context of the course “Internet Governance” St. Gallen University, 2014-10-06 Norbert Bollow <[email protected]> 1. Disclosures In any effort aimed at explaining matters of public policy (which can reasonably be seen as matters of politics) it is important for the person who is speaking to start by explaining their particular background and perspective. Hence I declare myself as follows: • I have come to the whole topic area of Internet Governance originally with a very much technical perspective, involving for example in-depth interest in the technical standards for email. • Over time I have however become more and more interested in the social, economic and political dimensions, becoming active in the civil society activities of in particular the Swiss Open Systems User Group /ch/open and Just Net Coalition. One of my major concerns is that what is happening and not happening in Internet governance must not be allowed to undermine democracy. • More generally, I'm looking for solutions to organize business and global governance in a sustainability oriented way. 2. Brief historical overview of the Internet success story The ways in which Internet Technical Standardization is conducted today are very much related to the work of the technical pioneers who have very significantly shaped these processes. We therefore start with a historical overview with a focus on (what are from my perspective at least) the key technical pioneers. 2.1 Louis Pouzin (*1931) The key technical innovation at the basis of the Internet was the invention of the “datagram”, and thereby the concept of “packet switching networks”, by Louis Pouzin, a Frenchman.

Lievrouw, Chair Technological time has been a topic of much theorization and dread, as both intellectuals and laypeople fear that human life is increasingly becoming secondary to the technological world. Feelings of despair and nihilism, perhaps attributable to social, political and economic upheavals brought by the synchronization of human life with technology, have been theorized by numerous scholars in a plethora of overlapping disciplines. What is left undertheorized is how technology develops in ways that might or might not actually foster these sensations of synchronicity, or speed. Technological development includes patterns of social coordination and consumption, as well as individual use and goals, that all relate to a sense of lived time. But what of the ways that technical design fosters these relations? What is the discourse of time in technological projects? This dissertation investigates the aforementioned questions in the context of NSF-funded Future Internet Architecture (FIA) projects—Named Data Networking (NDN), eXpressive Internet Architecture (XIA), and Mobility First (MF)—which are currently underway.
