This tutorial site includes information on fracture analysis and fracture mechanics. There are some case studies of failures which occurred in wire ropes, aircraft undercarriages and tow bars. A discussion of how design structures to reduce the risk and impact of structural failure is provided. Tutorial questions are given.

World Commission on Protected Areas
The WCPA (World Commission on Protected Areas) is one of 6 commissions of the World Conservation Union (also known as the IUCN). WCPA works by helping governments and others plan protected areas and integrate them into all sectors by providing strategic advice to policy makers. The site includes details of the protected areas programme, WCPA's activities by regions, biomes, and World Heritage work. The site also includes sections on news, events and publications.

Fossils in Antarctica: British Antarctic Survey
Although marching penguins add to Antarctica's allure, The British Antarctic Survey (BAS) has found fossil evidence that dinosaurs, marsupials, and forests inhabited the area long before penguins charmed the world with their trademark waddle. Since 1940, when the fossil collection of the BAS was started, it has grown to 40,000 specimens. The "Fossils" section of the BAShttp://www.antarctica.ac.uk/about_antarctica/geography/rock/fossils.php
website can be found on the left side of the homepage in the "About Antarctica" area, and is divided into two explanatory sections: "Fossils from the Antarctic" and "Fossil Locations in Antarctica". There are also links in each section, near the top right hand corner of the page, to "Type and Figured Fossil Collection" and "Fossils Picture Gallery". In the "Fossils from the Antarctic" section, the types of fossils found are explained and include: molluscs, arthropods, echinoderms and plants. The "Fossil Locations in Antarctica" section has a map of the three islands where a large amount of fossils have been found, along with descriptions of each island and what general types of fossils have been found on them.

The Microbial World: The Nitrogen cycle and Nitrogen fixation
Part of the Microbial World website at the Institute of Cell and Molecular Biology, University of Edinburgh, this page provides an introduction to the role of nitrogen in the biosphere, and describes the mechanism of biological nitrogen fixation. The site is produced by Jim Deacon as a resource for university teaching and learning.

Oral histories at the Niels Bohr Library and Archives
Interview transcripts are made available of several hundred tape-recorded interviews conducted by the staff of the American Institute of Physics Center for History of Physics and other historians with physicists, astronomers and others. Selected voice clips are also available online. The Niels Bohr Library and Archives of the American Institute of Physics holds the recordings of more than 1000 of these interviews and the transcripts for most of them are available in the Library. The main subject areas are quantum physics, nuclear physics, modern astrophysics and astronomy, solid state physics, laser science, multi-institutional collaborations in high-energy physics, space science and geophysics, physicists in industry, science education, science societies and institutions, and science and society.

Cambridge Physics: Past, Present and Future
Opened in 1874, the Cavendish Laboratory at the University of Cambridge is one of the oldest teaching laboratories in England. Researchers at the Laboratory have made key findings regarding the electron, positive rays, and the nucleus. This interactive site was created by staff members at the Cavendish (with the collaboration of the physics department) in order tohttp://www-outreach.phy.cam.ac.uk/camphys/
educate the public about their work and history. First-time visitors should scroll over the boxes on the homepage to learn more about some of their key discoveries as a way of becoming familiarized with their work. Moving on, the "Past, Present, Future" area provides a virtual tour of the Cavendish Laboratory, along with biographies of the key figures who've worked at the Laboratory since the 19th century.
