Directory
Science and mathematics collects references, databases and study material for science and maths subjects. The listings cover chemistry, physics, biology, astronomy, earth science and maths, with a mix of reference databases, course pages, calculators, simulations and self-assessment tools. Some entries are large public databases such as compound or species catalogues, and others are small teaching sites or video series. Worth checking: the level each resource aims at, the date of its data and whether the authors are named. Accuracy matters most here, so prefer sources that explain how their numbers were produced.

An open-source software platform for distributed computing using volunteered resources. The BOINC app downloads scientific computing jobs and runs them in the background on a user's computer. About 30 science projects use it, investigating diseases, climate change, pulsars and other research.
Seeing Theory is an archived site offering a visual introduction to probability and statistics through interactive visualizations. It covers six chapters: basic probability, compound probability, probability distributions, frequentist inference, Bayesian inference and regression analysis. It was created by Daniel Kunin while an undergraduate at Brown University.
The Biology Project is an educational site from the University of Arizona's Department of Biochemistry & Molecular Biophysics. It provides instructional materials on topics including cell biology, human biology, immunology, Mendelian genetics, molecular biology and developmental biology. The site was last revised in July 2004 and is hosted by the Department of Molecular & Cellular Biology.
WebPath is an educational resource hosted by the University of Utah Eccles Health Sciences Library that contains pathology images, text, examinations and tutorials for medical education. It includes over 2700 images illustrating gross and microscopic pathologic findings and radiologic imaging, over 1300 examination items, and more than 20 tutorials. It is intended for students and workers in the health care sciences studying pathology.
