National Shrine of St Therese

Waterfall Glen is a forest preserve in Downers Grove Township, DuPage County, Illinois, between the towns of Darien and Lemont, covering 2,492 acres (1,008 ha). It contains several waterfalls on Sawmill Creek as it empties into the Des Plaines River. Rocky Glen Falls, the largest waterfall in the preserve, is actually a natural dam in the valley glen. In the 1930s, the Civilian Conservation Corps helped restore the waterfall to its naturally tiered state, after years of erosion due to runoff from a nearby mill. It completely surrounds Argonne National Laboratory. It is also home to a popular model airplane field, located in the southwest section of the forest preserve. Hikers can also make the interior trip to St. Patrick Cemetery nestled deep in the preserve. Waterfall Glen's tallgrass prairies, bogs, and Midwestern oak savannas contain 740 native plant species, 75 percent of all the plants known to grow naturally in DuPage County. Over 300 species of mammals, birds, fish, amphibians, and reptiles and another 300 species of invertebrates use the forest preserve, either year-round or during their migrations.

Argonne National Laboratory is a federally funded research and development center in Lemont, Illinois, United States. Founded in 1946, the laboratory is owned by the United States Department of Energy and administered by UChicago Argonne LLC of the University of Chicago. The facility is the largest national laboratory in the Midwest. Argonne had its beginnings in the Metallurgical Laboratory of the University of Chicago, formed in part to carry out Enrico Fermi's work on nuclear reactors for the Manhattan Project during World War II. After the war, it was designated as the first national laboratory in the United States on July 1, 1946. In its first decades, the laboratory was a hub for peaceful use of nuclear physics; nearly all operating commercial nuclear power plants around the world have roots in Argonne research. More than 1,000 scientists conduct research at the laboratory, in the fields of energy storage and renewable energy; fundamental research in physics, chemistry, and materials science; environmental sustainability; supercomputing; and national security. Argonne formerly ran a smaller facility called Argonne National Laboratory-West (or simply Argonne-West) in Idaho next to the Idaho National Engineering and Environmental Laboratory. In 2005, the two Idaho-based laboratories merged to become the Idaho National Laboratory.Argonne is a part of the expanding Illinois Technology and Research Corridor.

Chicago Pile-5 (CP-5) was the last of the line of Chicago Pile research reactors which started with CP-1 in 1942. The first reactor built on the Argonne National Laboratory campus in DuPage county, it operated from 1954-1979.CP-5 was a thermal-neutron reactor using enriched uranium as fuel and heavy water as coolant and as a neutron moderator. It produced neutrons for use in research. The reactor had an output rating of 5 megawatts.Cleanup and decommissioning of the site of CP-5 was started in 1991 completed in 2000. The cleanup process included removal of all contaminated equipment and spent fuel, decontamination of the reactor vessel and associated plumbing, and removal of the spent fuel pool, reactor internals and the hot cell liner. The accessible areas of the structure have been certified as having radiation levels equivalent to background radiation.

Now the NBL Program Office, the New Brunswick Laboratory (NBL), was a United States government-owned and operated, center of excellence in the measurement science of nuclear materials. It was established in 1949 by the Atomic Energy Commission and was located in New Brunswick, New Jersey. It was relocated between 1975 and 1977 and was located, as a Federal enclave, on the site of Argonne National Laboratory, about 40 kilometers (25 miles) southwest of Chicago, Illinois. NBL was part the Department of Energy's Office of Science Chicago Office.NBL is the U.S. Government's Nuclear Materials Measurements and Reference Materials Laboratory and the National Certifying Authority for nuclear reference materials and measurement calibration standards. As an internationally recognized Federal laboratory, NBL provides reference materials, measurement and interlaboratory measurement evaluation services, and technical expertise for evaluating measurement methods and safeguards measures in use at other facilities for a variety of Federal program sponsors and customers.

Edward Paul Krynski (September 12, 1927 – November 15, 2004) was a pinball game designer and innovator who worked for D. Gottlieb & Co between 1965 and 1984. During this time Krynski designed more than 200 games and innovated new pinball standards such as the laneways to the flipper, carousel targets, vari-targets, multiple drop targets, and the first solid state pinball machine with the speaker in the backbox instead of the bottom cabinet. Krynski is a member of the Pinball Hall of Fame. The first pinball machine designed by Krynski was Hi Straight, released in December 1959, and the last was El Dorado City of Gold, in October 1984. The Internet Pinball Machine Database identifies 225 machines designed by Krynski, including "300", 2001, 4 Square, The Amazing Spider-Man, El Dorado City of Gold, Genie, Spirit of 76, Central Park, Royal Flush, Big Shot, and Sing Along.Stan Lee, the co-creator of Spider-Man and public face of Marvel Comics, claimed ownership of one of Krynski's first The Amazing Spider-Man pinball machines off the assembly line in 1980 and kept it in his Marvel office until he auctioned it as part of his "Stan Lee collection". Lee said that "Over the years, I have spent countless frustrating yet perversely enjoyable hours attempting to play on it, as have numerous colleagues, friends and business associates (some quite famous, though a combination of modesty, shame and my legendary bad memory prevents me from divulging their names here) during their unrelenting pilgrimages to my office. In fact, I think many of these scions of arts and industry came over JUST to beat me up at pinball. I hope its new owner will be a better player than I am."Krynski served in the U.S. Navy during World War II.

The Track Imaging Cherenkov Experiment (TrICE) is a ground-based cosmic ray telescope located at Argonne National Laboratory near Chicago, IL. The telescope, which contains a Fresnel lens, eight spherical mirrors, and a camera with 16 multianode photomultiplier tubes, uses the atmospheric Cherenkov imaging technique to detect Cherenkov radiation produced when cosmic rays interact with particles in the Earth's atmosphere. The telescope is primarily a research and development tool for improving photomultiplier tube cameras and electronic systems for future gamma and cosmic ray telescopes. It is also used to study the energy and composition of cosmic rays in the TeV–PeV range, and the collaboration is currently conducting pioneering work in detecting direct Cherenkov signals from cosmic rays.
