Flowerfield was a station along the Port Jefferson Branch of the Long Island Rail Road in Saint James, New York. The station opened in 1910 on a 1,000-acre (400 ha) parcel purchased by John Lewis Childs to grow plants and seeds, which was later acquired by the Gyrodyne Company of America. The second floor of the station even had a small greenhouse. The station agency closed in 1944. On July 2, 1959, the LIRR petitioned with the New York State Public Service Commission for permission to discontinue all passenger services and team tracks at the station.Reopening the Flowerfield station, along with a closure of the St. James station, was proposed in the mid-1990s as part of a plan to redevelop the Gyrodyne site.

Three Village Central School District is a school district located on Long Island, New York. It serves Setauket, East Setauket, Stony Brook, Poquott, Head of the Harbor, Old Field, and small portions of Port Jefferson, Saint James and Lake Grove. Its name came from the older, original "Three Villages" of Setauket, Stony Brook and Old Field after the merger of the Stony Brook and Setauket school districts in the 1960s. Ward Melville, a local philanthropist, was a proponent of the Three Village school district, and contributed land for its new schools. The school district is renowned for its InSTAR program, a three-year science research program which produces record numbers of Regeneron Science Talent Search (formerly Intel STS) semifinalists. In 2008, the district's program produced 13 semifinalists, the most semifinalists from a single school in the entire nation. The district's Intellectually Gifted (I.G.) program is housed at its Nassakeag Elementary School. The Three Village CSD has been represented at nationals for Science Olympiad and by various varsity sports teams.The current Superintendent of Schools is Dr. Kevin Scanlon.

The Simons Center for Geometry and Physics is a center for theoretical physics and mathematics at Stony Brook University in New York. The focus of the center is mathematical physics and the interface of geometry and physics. It was founded in 2007 by a gift from the James and Marilyn Simons Foundation. The center's current director is physicist Luis Álvarez-Gaumé.

The C. N. Yang Institute of Theoretical Physics (YITP) is a research center at Stony Brook University. In 1965, it was the vision of then University President J.S. Toll and Physics Department chair T.A. Pond to create an institute for theoretical physics and invite the famous physicist Chen Ning Yang from Institute for Advanced Study to serve as its director with the Albert Einstein Professorship of Physics. While the center is often referred to as "YITP", this can be confusing as YITP also stands for the Yukawa Institute for Theoretical Physics in Japan. The active research areas of the institute include: quantum field theory, string theory, mathematical physics and statistical mechanics. The YITP is situated on top of the Math Tower, home to the Department of Mathematics which is connected to the Department of Physics and the Simons Center for Geometry and Physics—therefore the physicists enjoy intimate interactions with the mathematicians. This close relationship dates back to the friendship of C.N. Yang and the mathematician James Harris Simons. Founded in 1967, YITP celebrated its 50th anniversary in 2017. During the time span, the YITP has produced significant results in different areas, most notably was the discovery of supergravity in 1976 by Peter van Nieuwenhuizen, Daniel Z. Freedman, and Sergio Ferrara, who were all working there at the time. It houses two Breakthrough Prize in Fundamental Physics laureates; Peter Van Nieuwenhuizen (2019) and Alexander Zamolodchikov (2024). Former director Chen Ning Yang is a Nobel Prize in Physics laureate (1957).

Island Federal Credit Union Arena, commonly referred to as Island Federal Arena, is a 4,000-seat multi-purpose arena in Stony Brook, New York. It is the home of the Stony Brook Seawolves men's and women's basketball teams. Originally built in 1990 as the Stony Brook University Arena, it underwent a $21.1 million renovation in 2012–14. Naming rights were sold to a regional credit union, Island Federal Credit Union. The Island Federal Arena has hosted the America East Conference men's basketball tournament finals in 2012 and 2016, as well as the NBA G League Finals in 2019.It contains four scoreboards and two video boards, plus four luxury suites with 16 seats each. It is also used for concerts, trade shows, conventions, graduations, and other special events.
