Atrevida: Game Programming Tutorials
Although it is labeled as an introduction to PC game programming, the tutorials given on Atrevida additionally cover many aspects of mathematics and general computer science. A modest background in the C language is suggested, but many of the sections involve more theory than actual programming. There are nearly twenty topics that explain basic computer operation, graphics programming, and the 80x86 assembler. A very interesting section describes sound waves and compression techniques, while ano
Design a Parachute
After a discussion about what a parachute is and how it works, students will create a parachute using different materials that they think will work best. The students will test their designs, which will be followed by a class discussion (and possible journal writing) to highlight which paper material worked best.
PicSNP: A Catalog of Non-Synonymous SNP
Maintained by Hangil Chang at the University of Tokyo, PicSNP "is a catalog of non-synonymous Single Nucleotide Polymorphism (SNP) in the human genome." Recently updated, the database allows users to select SNPs by gene name, function of affected genes, biological process relevant to affected genes, or cellular component that contain affected genes. The site does not include much instruction on how to use the database, meaning it is most suitable for users who are familiar with the subject.
ECOTOX Database System
The US Environmental Protection Agency (EPA) provides this database of chemical toxicity. Three individual EPA databases are combined to provide information on chemical-specific toxicity values for aquatic and terrestrial plants and animals. Users can search for research reports by chemical name, species name, or environmental effect. The site has informative help files and browse features. This Web site is useful for evaluating industrial chemicals or for environmental assessment research.
