Physics

American Institute of Physics advances, promotes and serves the physical sciences for the benefit of humanity.

This is an interactive Periodical Table Chart that enables you to click on a particular element and find information like atomic weight, ionization energy, ground-state level, and ground-state configuration. It also links to various databases with lots of research information.

The National Institute of Standards and Technology (NIST) provides interactive tables for constants.

The Institute of Physics (IOP) is the professional body and learned society for physics in the UK and Ireland, with an active role in promoting co-operation in physics around the world. We strive to make physics accessible to people from all backgrounds.

Physics research at NIST includes everything from improving the safety of medical radiation procedures to developing future "quantum information" technologies that generate unbreakable codes. NIST provides the measurements, standards, and technical expertise scientists and industries need to push the limits of the fundamental properties of nature.

The National Nuclear Data Center (NNDC) collects, evaluates, and disseminates nuclear physics data for basic nuclear research and applied nuclear technologies. The NNDC is a worldwide resource for nuclear data. The information available to the users of NNDC services is the product of the combined efforts of the NNDC and cooperating data centers and other interested groups, both in the United States and worldwide.

Textbook on classical mechanics that compiles 15 years of lecture notes by Prof. Douglas Cline, from the Physics Department at the University of Rochester.

A tour of quarks, neutrinos, the Higgs boson, extra dimensions, dark matter, accelerators and particle detectors from the Lawrence Berkeley National Lab.
