This website is part of the National Science Digital Library and is " network of free online resource collections supporting faculty, students, and teachers in Physics and Astronomy Education." The site includes a link to Physics To Go, an "online monthly mini-magazine and a collection of more than 900 websites" of images, activities, and information.
- Contributions of 20th Century Women to Physics
This site is an "archive presenting and documenting some important and original contributions made before 1976 by 20th century women." 83 women physicists are profiled.
- Einstein Archives Online
This site provides "online access to Albert Einstein’s scientific and non-scientific manuscripts held by the Albert Einstein Archives at the Hebrew University of Jerusalem and to an extensive Archival Database."
- Energy Citations Database
The Energy Citations Database (ECD) was created was created and developed by the Department of Energy's (DOE) Office of Scientific and Technical Information with the" science-attentive citizen in mind". "It provides free access to over 2,466,000 science research citations with continued growth through regular updates. There are over 300,000 electronic documents, primarily from 1943 forward, available via the database. It includes bibliographic citations to report literature, conference papers, journal articles, books, dissertations, and patents."
- Eric Weisstein's World of Physics
This site is an alphabetical index created by Eric Weisstein of physics definitions, derivations, equations, formulas, and figures.
- Fermi National Accelerator Laboratory (FNAL)
This Lab's states that its mission is to advance "the understanding of the fundamental nature of matter and energy by providing leadership and resources for qualified researchers to conduct basic research at the frontiers of high energy physics and related disciplines."
- Hands on CERN: English version
This award-winning site is "aimed at teachers and high school students studying natural sciences. The purpose of this project/course is to increase understanding of the most fundamental processes inside matter, and to explain modern research about particle collisions."
- How EveryThing Works
This site attempts to explain the "physics of everyday life."
- Inspire: the High-Energy Physics Literature Database
This database contains over a half million citations to high-energy and astroparticle physics related articles, including journal papers, preprints, e-prints, technical reports, conference papers and theses. The database provides citation tracking of an article through its life as an e-print through publication as a journal article. It is a joint project of the Stanford Linear Accelerator Center (SLAC), Deutsches Elektronen Synchrotron (DESY), the Fermi National Accelerator Laboratory and CERN, the European Organization for Nuclear Research.
- Institute of Physics
This professional society for physicists is based in London. Their Physics in Society team are the sponsors of Physics.org: a Guide to Physics on the Web (see entry for this site for more information)
- Max Planck Institute for Gravitational Physics
Research at this Institute, also known as the Albert Einstein Institute is aimed at investigating Einstein’s relativity and beyond: mathematics, quantum gravity, astrophysical relativity, gravitational wave astronomy, data analysis and cosmology."
- National Nuclear Data Center (NNDC) Databases
Five nuclear structure and decay databases, four nuclear reaction databases, and two bibliographic databases may be accessed from this site.
- NIST Physical Measurement Laboratory
Links to the online databases maintained by the Physical Measurement Laboratory may be found here. The databases include data on fundamental physical constants, atomic and molecular spectroscopy, ionization cross sections, absorption of x-rays and gamma rays, radiation dosimetry, half-life measurements, atomic weights, and condensed matter physics.
- Optical Society of America
- Particle Adventure: the Fundamentals of Matter and Force
This award-winning site is an "interactive tour of quarks, neutrinos, antimatter, extra dimensions, dark matter, accelerators and particle detectors from the Particle Data Group of Lawrence Berkeley National Laboratory."
- Physics Central
This site sponsored by the American Physical Society. Their stated aim with this site is to "answer your questions on how things work and keep you informed with daily updates on physics in the news."
- Physics.org: a Guide to Physics on the Web
The Institute of Physics' Physics in Society team are the sponsors of this site. They aim "to be your guide and show you the best physics places on the web."
- PhysLink.com: Physics and Astronomy Online Portal
This award-winning site is a "comprehensive physics and astronomy online education, research and reference web site."
- SPIRES-HEP Database
This database contains over a half million citations to high-energy and astroparticle physics related articles, including journal papers, preprints, e-prints, technical reports, conference papers and theses. The database provides citation tracking of an article through its life as an e-print through publication as a journal article.
- Stanford Linear Accelerator Center (SLAC)
"SLAC's research programs explore the structure and dynamics of matter and the properties of energy, space, and time—at the smallest and largest scales, in the fastest processes, and at the highest energies." It is the home of to a two-mile linear accelerator—the longest in the world.
- Thermodynamics Research Laboratory
This laboratory is located at the University of Illinois Chicago. This laboratory maintains a list of Nano, Quantum & Statistical Mechanics & Thermodynamics Data & Property Calculation Websites; as well as a list of interesting web sites.
- Virtual Library: Physics
"The VL is the oldest catalog of the web." "It is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are expert." The Physics section is divided by the various sub-disciplines of physics; e.g., acoustics, beam physics, laser physics, nuclear physics, and optical science and engineering.
