We list here many important events in the history of astronomy, particularly high-energy astronomy (X-ray astronomy, gamma-ray astronomy and cosmic-ray astronomy), with particular emphasis on events concerning space-based observatories with X-ray and gamma-ray detectors on board which observed cosmic (i.e., non-solar) sources. (Some of the major events in planetary exploration missions are listed, but for a comprehensive chronology, see the NSSDC Chronology of Lunar and Planetary Exploration). A graphical version of the dates of operation of high-energy astrophysics missions is also available, as is a review paper on X-ray astronomy missions up to the early 1990s.

The Association for History and Computing is an international organisation which aims to promote and develop interest in the use of computers in all types of historical study at every level, in both teaching and research.
The AHC was proposed at a large conference at Westfield College, University of London, in March 1986. At a second conference at Westfield, in March 1987, it was founded and its constitution approved. A central co-ordinating body, the Council, organises the AHC's international activities, including annual international conferences, and supervises publications.

The Bradbury Science Museum's primary mission is (1) to interpret Laboratory research, activities, and history to official visitors, the general public, and Laboratory employees; (2) to promote greater public understanding of the Laboratory's role in national security programs; (3) to assist the taxpaying public in making informed judgments in these matters; and (4) to contribute to visitors' knowledge of science and technology and to improve the quality of math and science education in northern New Mexico.

The Buffalo Museum of Science, through collections, research, education and interpretation, provides opportunities for all people to develop a scientific understanding of the natural and cultural world with an emphasis on the Greater Niagara Region. The Museum challenges everyone to use their knowledge of science to enhance respect for each other and the environmen

Mathematics has been vital to the development of civilization; from ancient to modern times it has been fundamental to advances in science, engineering, and philosophy. As a result, the history of mathematics has become an important study; hundreds of books, papers, and web pages have addressed the subject in a variety of different ways.

Africanized honey bees have moved into the Southwest and are here to stay. In addition to the safety issues that need to be addressed because of the defensiveness of these bees, honey bees are also fascinating subjects to study. These lesson plans were developed to familarize students with honey bees and bee safety issues through a variety of interesting activities.

  Since 1992, the Electronic Text Center at the University of Virginia Library has pursued twin missions with equal seriousness of purpose:
to build and maintain an internet-accessible collection of SGML and XML texts and images;
to build and maintain user communities adept at the creation and use of these materials.

Long before condoms came in rainbow colors and exotic skins, legendary lover Casanova was sewing together strips of fine linen. Centuries before nonoxynol 9, young women in Constantinople shook the gritty sand from sea sponges and dipped them in lemon juice before insertion. Contraception has a long and inventive history. Now there is a museum dedicated to one of humankind's most persistent quests

After reading James Watson's The Double Helix (1968), Anne Sayre began working on an account of the role of Rosalind Franklin in the discovery of the structure of DNA. Sayre felt that the portrait of her friend Franklin (who had died in 1958) that emerged from Watson's book was not only unflattering, but wrong. After publication of Rosalind Franklin and DNA in 1975, Sayre deposited all her research materials with the ASM Archives: background materials and notes; correspondence; and interviews (taped and, in some instances, transcribed). Of additional interest is the file of post-publication correspondence, which provides insight into the reaction to Sayre's book.
