Learn about planets outside our solar system through Exoplanets and Alien Solar Systems by Tahir Yaqoob, Ph.D., a book in our online store book collection.

Fundamental Physics

Physics is the study of basic properties, materials, and forces in our Universe. Our new physics section will start off with some background material about space, time, and matter. It will also include sections on mechanics, electricity and magnetism, thermal physics, atomic physics and particle physics, and tools for math and science (vectors, coordinate systems, units of measurement, etc.).

The new physics section will also have links to many data sources relevant to Earth and space science. The links below provide access to some of the physics-related materials currently on the site. They are organized roughly into the categories we will use in the forthcoming physics section.
