What's the difference between i.e. and e.g.?
the first U.S. national research laboratory, located in Argonne, Illinois, some 40 km (25 miles) southwest of Chicago, and operated by the University of Chicago for the U.S. Department of Energy. It was founded in 1946 to conduct basic nuclear physics research and to develop the technology for peaceful uses of nuclear energy. Argonne National Laboratory now supports more than 200 basic and applied research programs-in science, engineering, and technology-that are directed to maintain basic scientific leadership, guide energy-resource development, improve nuclear-energy technology, and promote environmental-risk management.
