All Physics and Astronomy: Web Resources

A quick guide to physical constants, astronomy data, unit conversions, and other useful information for physics and astronomy.

Provides a summary of most of the units of measurement in use today, along with the appropriate conversions needed to change them into standard units of the SI system. Includes access to 40 different calculators for automatic conversions, and a printable pocket guide listing the most common conversion units.

Provides basic and advanced information on string theory and its connections with areas of study including cosmology and mathematics.

Provides general information on physics-related topics as well as links to other web sites with useful physics information. Users should register for free to use this site to the fullest.

Presents Einstein's theory of relativity in a clear, easily understood manner and includes related links for further and more in depth exploration.

Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.

Web site supporting the book and PBS NOVA program The Elegant Universe, covering the topic of string theory. Contains the full NOVA progarm and additional materials.

This site provides access to research on mathematics, quantum gravity, astrophysical relativity, and gravitational wave astronomy, including open access review articles and free access to most AEI publications. Max Planck is also known as the Albert Einstein Institute.

Contains biographical and bibliographical information for 83 women who made theoretical contributions to physics from 1900 to 1975.

Features basic information and references on a large number of topics in physics, including astrophysics, fluid mechanics, modern physics, optics, and thermodynamics.

arXiv is a free distribution service and an open-access archive for 1,931,221 scholarly articles in the fields of physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. Materials on this site are not peer-reviewed by arXiv.

Search over 3 million documents, plus patents and government data. Most atricles require a login to access, but when free full text access is available, it is provided.

The ComPADRE Digital Library is a network of free online resource collections supporting faculty, students, and teachers in Physics and Astronomy Education.

Minute Labs (minutelabs.io)

Fun, interactive, research-based simulations of physical phenomena from the PhET™ project at the University of Colorado.

Provides access to a research-quality global climate model (GCM) with a user-friendly interface that runs on desktop computers.

A commentary site (blog) for those interested in climate science run by working climate scientists . It aims to objectively educate, and the discussion is restricted to scientific topics and excludes political or economic implications of the science.

Historical archives of weather and climate data of all types, including the Storm Events Database and an archive of weather satellite images for nearly every day from July 1, 1992 to present. NOTE: not all data is free; see link on main page for free data.

Climatological Database for the World's Oceans. Contains daily oceanic climatological data compiled from naval logbooks from 1750-1859 covering the North and South Atlantic, Indian, and Pacific oceans.

Provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system.

Provides information on the history of the universe, focusing on the seven major epochs.

A "mini-net" of information on astronomy and astrophysics.

Maintains and provides access to three bibliographic databases containing more than 5.6 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. NOTE: please note that searching is free, but full text access to recent articles requires a subscription to the journal.

An extensive list of links to astronomy-related information on the Internet.

An interactive sky map allowing users to enter photos and comments.
