Math Planet is a free platform for learning mathematics, offering high school courses in Pre-algebra, Algebra 1, Algebra 2 and Geometry, plus SAT and ACT preparation with practice tests and tips. It is run by Mattecentrum, a non-profit organization.
Bartosz Ciechanowski's site presents interactive articles about science and engineering, including an article on the Moon covering its motion in space, its illumination, and its path around Earth. The articles include draggable visualizations and sliders for controlling viewpoint and date and time.
A personal site about model and high-power rocketry by John Coker, documenting his rocket fleet and launch reports. It also hosts how-to articles on techniques and research, and links to related resources.
The Catalogue of Life is described as the most complete authoritative list of the world's species, maintained by hundreds of global taxonomists. It lists species counts for Animalia, Plantae, Fungi, and other kingdoms. The active release is COL26.9 XR, and the catalogue includes a base release verified by taxonomic experts and an Extended Release with extra data.
MathJax is a JavaScript display engine for mathematics that works in all browsers. It provides tools to transform print content into accessible web content and ePubs, and the team offers training and consultancy on online teaching materials.
Jetphotos is an educational resource for documentaries, courses, books, reference material, or self-learning.
