The VL is the oldest catalog of the web, started by Tim Berners-Lee, the creator of html and the web itself. Unlike commercial catalogs, it is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are expert; even though it isn't the biggest index of the web, the VL pages are widely recognised as being amongst the highest-quality guides to particular sections of the web.
The Columbia STS-107 mission lifted off on January 16, 2003, for a 17-day science mission featuring numerous microgravity experiments. Upon reentering the atmosphere on February 1, 2003, the Columbia orbiter suffered a catastrophic failure due to a breach that occurred during launch when falling foam from the External Tank struck the Reinforced Carbon Carbon panels on the underside of the left wing. The orbiter and its seven crewmembers (Rick D. Husband, William C. McCool, David Brown, Laurel Blair Salton Clark, Michael P. Anderson, Ilan Ramon, and Kalpana Chawla) were lost approximately 15 minutes before Columbia was scheduled to touch down at Kennedy Space Center. This site presents information about the STS-107 flight, as well as information related to the accident and subsequent investigation by the formal Columbia Accident Investigation Board.
This website from the NASA History Office has a wealth of information about the shuttle Columbia mission itself, the loss of the shuttle in February 2003, and the ensuing investigation. There are formal biographies of crew members, extremely detailed timelines, and a twenty-page document with accompanying acronym list entitled "STS-107 Accident Investigation Ground Track, Events Summary, and Sighting Data." A number of images and links to documents from NASA, Congress, and the White House are available, as is full information about the Columbia Accident Investigation Board, from its charter and members, to the six-volume report. Professionally-compiled bibliogaphies on Space Shuttles, the Columbia accident, and organizational culture are also included. Finally, reflections from the public gathered on the web are collected and displayed, adding individual responses to the loss of the shuttle to this very informative site.
Making the Modern World brings you powerful stories about science and invention from the eighteenth century to today. It explains the development and the global spread of modern industrial society and its effects on all our lives. The site expands upon the permanent landmark gallery at the Science Museum, using the Web and dynamic multimedia techniques to go far beyond what a static exhibition can do.
Making the Modern World is a vast online exhibit from the Science Museum of London that covers science and society in the modern era, from traditional research and inventions and engineering, to social sciences and everyday life. There are many ways to explore the hundreds of images, audio files, and texts of the exhibit that begins with “Enlightenments and Measurement” in 1750 and concludes with the “Age of Ambivalence” in 2000. The largest section of the site is the Stories and Timelines, which is in narrative and chronological form. There are guided tours along the themes of “Technology as Passport,” “Women Making the Modern World,” and “Conflict in the Modern World.” The Daily Life Section has six categories that include personal, leisure, work, health, and control, and the stories of nine contemporary people's interactions with technology, some inventors, others learning how to handle a screwdriver and "DIY- Do It Yourself." The Icons of Invention includes more than 100 objects from science, technology, and medicine, while the Learning Modules cover biology, English, chemistry, geography, history, mathematics, and psychology. Throughout the site are subsections called "rich media scenes" with moving images and sound that provide interaction with catalogued images and quizzes within a particular story. Finally, there are basic and advanced search options to navigate quickly to a particular item or term.
Science & Society Picture Library represents the collections of the National Museum of Science & Industry, Science Museum, National Museum of Photography, Film & Television, National Railway Museum.
The Science and Society Picture Library of the British National Museum of Science and Industry combines collections of the Science Museum, National Museum of Photography, Film & Television, and the National Railway Museum all on one website. It allows for searching or browsing of over 35,000 images, each of which can be sent as e-cards, or saved into a "wishlist" for second viewing or ordering reproductions. The images are of decent size to be viewed online, display a caption, and are completely categorized by keywords and fully seachable. This is an amazing resource for anyone interested in images of science and society up to the present day.
"Before the Web" is an online research project designed for the practitioners of the online services industry and its era. It is an interactive, digital variation of the oral history, the most common traditional technique used to collect the first-hand accounts from people who witnessed or took part in important events and eras.
The Internet boom and bust of 1996 to 2002 was the most important business phenomenon of the past several decades. In the wake of this historic period, we have an unprecedented opportunity to learn from our past mistakes and successes.
To help us learn from history, we are creating the Business Plan Archive (BPA) to collect business plans and related documents from the dot com era. These plans – the “blueprints” that lay out the assumptions and strategies of Internet entrepreneurs – will enable entrepreneurs and researchers to conduct both qualitative and quantitative research.
The Business Plan Archive, a project of Prof. David Kirsch at the University of Maryland, collects business plans and related documents from the dot com era to preserve and provide them for study of the Internet boom and bust of the last decade. The communication and records of these companies were all created electronically, and in the Archive are the Word documents, Power Point presentations, and emails of more than 2,000 failed businesses. “Top Ten Lessons from the Dot Com Meltdown” and “A Statistical Summary of the Dot Com Shakeout” provide context for the documents, which include funding requests, memos, draft press releases, anecdotal descriptions or images, and contract and investment-related information. For some companies there is a collection overview as well. The Archive can be searched by company name, alphabetical listing, market sector, market audience, or type of available information, making it easy to find companies of interest. Visitors are able to add more information to the Archive about any company’s events, files, or background, or just add a comment. A thorough Question and Answer Section accompanies the materials, along with links to the numerous articles and news coverage of the Archive.
Here you can find a PostScript (460 Kbytes), gzipped PostScript (146 Kbytes) and pdf (358 Kbytes) version of Shannon's paper. PDF files can be viewed by Adobe's acrobat reader. Tarred and gzipped contents of the directory (63 Kbytes) that contain the LaTeX code for the paper is also available.
Am I pregnant? The answer to this age-old question once demanded a combination of guesswork, intuition, and time. In 1978, however, the long wait to know for sure became a thing of the past. Trumpeted by advertisements as “a private little revolution,” the first home pregnancy tests started appearing on drug store shelves that year. A quarter of a century later, innovations promise to make even the telltale thin blue line obsolete. This web site looks at the history of the home pregnancy test—one of the most ubiquitous home healthcare products in America—and examines its place in our culture.
The home pregnancy test works by identifying the presence of the “pregnancy hormone,” human chorionic gonadotropin (hCG), in urine. Research that led to a sensitive, accurate test for hCG was done by scientists in the Reproductive Research Branch of the National Institute of Child Health and Human Development at NIH.
A Thin Blue Line: The History of the Pregnancy Test Kit, an online exhibit at the National Institutes of Health, explores the history of the pregnancy test kit from the laboratory to the digital age and invites women to share their personal stories through an online survey. In addition to the scientific background on the research that led to the development of the test, it also includes an historical timeline of pregnancy testing, as well as early advertisements for the test and portrayals of the test in television. There are excerpts from oral histories and interviews with Judith Vaitukaitis, M.D. and Glenn Braunstein, M.D., who in the early 1970’s collaborated on the experiments that led to the sensitive assay for hCG, the “pregnancy hormone.” The site is an interesting introduction to a modern technology that is so widespread and easily accessible as to be taken for granted.
