They are the main concepts covered by lbl.gov.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics

Lawrence Berkeley National Laboratory Confidence: 86%

The Lawrence Berkeley National Laboratory (LBNL or LBL), commonly referred to as Berkeley Lab, is a United States national laboratory located in the Berkeley Hills near Berkeley, California that conducts scientific research on behalf of the United States Department of Energy (DOE). It is managed and operated by the University of California. The laboratory overlooks the University of California, Berkeley's main campus.

United States Department of Energy Confidence: 84%

The United States Department of Energy (DOE) is a Cabinet-level department of the United States Government concerned with the United States' policies regarding energy and safety in handling nuclear material. Its responsibilities include the nation's nuclear weapons program, nuclear reactor production for the United States Navy, energy conservation, energy-related research, radioactive waste disposal, and domestic energy production. It also directs research in genomics; the Human Genome Project originated in a DOE initiative. DOE sponsors more research in the physical sciences than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories.

Office of Science Confidence: 81%

The Office of Science is a component of the United States Department of Energy (DOE). The Office of Science is the lead federal agency supporting fundamental scientific research for energy and the Nation’s largest supporter of basic research in the physical sciences. The Office of Science portfolio has two principal thrusts: direct support of scientific research and direct support of the development, construction, and operation of unique, open-access scientific user facilities that are made available for use by external researchers.

University of California Confidence: 77%

The University of California (UC) is a public university system in the U.S. state of California. Under the California Master Plan for Higher Education, the University of California is a part of the state's three-system public higher education plan, which also include the California State University system and the California Community Colleges System.

Laboratory Confidence: 72%

A laboratory (CommE or, AmE; informally, lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.
