It's a Family Matter! The third family of fundamental particles of matter became more than just a theory with the discovery of the tau lepton by Martin Perl. It is the 20th Anniversary of Perl receiving the Nobel Prize in Physics for his discovery, which took place 40 years ago (1975). Evidence of this third family of fundamental particles inspired confidence in the Standard Model, the theory being developed in the 1970s by physicists to explain matter and the forces of nature.

Welcome to the Department of Energy (DOE) Research and Development (R&D) Accomplishments, a central forum for information about the outcomes of past DOE R&D that

  • have had significant economic impact,
  • have improved people's lives, or
  • have been widely recognized as remarkable advances in science.

An R&D accomplishment is the outcome of past DOE or predecessor research whose benefits are being realized now.

This site is comprised of the R&D Accomplishments Database, Featured Scientists/Topics pages, Laureates, Interesting Insights, and Snapshots. More information about DOE R&D Accomplishments content is available on the About page.

Remarkable advances in science are widely recognized when they lead to the Nobel Prize or the Enrico Fermi Award. Research and development accomplishments are exemplified by over one hundred ten (110) Nobel Laureates associated with the Department of Energy and/or predecessor agencies and by sixty (60) Enrico Fermi Award winners. DOE R&D Accomplishments provides information about these Nobel Laureates, the Enrico Fermi Laureates, and their outstanding achievements.

DOE R&D Accomplishments improves the visibility of DOE and predecessor accomplishments by broadening and integrating access to important advances made possible by past research and development, thus showcasing the Department's proud heritage.
