Johns Hopkins

Johns Hopkins (May 19, 1795 – December 24, 1873) was an American entrepreneur, abolitionist and philanthropist of 19th-century Baltimore, Maryland.

His bequests founded numerous institutions bearing his name, most notably Johns Hopkins Hospital, and Johns Hopkins University (including its academic divisions such as Johns Hopkins School of Nursing, Johns Hopkins School of Medicine, Johns Hopkins Carey Business School, and Johns Hopkins Bloomberg School of Public Health).

A biography entitled Johns Hopkins: A Silhouette written by his cousin, Helen Hopkins Thom, was published in 1929 by the Johns Hopkins University Press.

Early life

Johns Hopkins was born on May 19, 1795. He was one of eleven children born to Samuel Hopkins (1759–1814) of Crofton, Maryland, and Hannah Janney (1774–1864), of Loudoun County, Virginia. His home was Whitehall, a 500-acre (two km²) tobacco plantation in Anne Arundel County. His first name was inherited from his grandfather Johns Hopkins who received his first name when his mother Margaret Johns married Gerard Hopkins.

Applied physics

Applied physics is physics which is intended for a particular technological or practical use. It is usually considered as a bridge or a connection between physics and engineering.

"Applied" is distinguished from "pure" by a subtle combination of factors such as the motivation and attitude of researchers and the nature of the relationship to the technology or science that may be affected by the work. It usually differs from engineering in that an applied physicist may not be designing something in particular, but rather is using physics or conducting physics research with the aim of developing new technologies or solving an engineering problem. This approach is similar to that of applied mathematics. In other words, applied physics is rooted in the fundamental truths and basic concepts of the physical sciences but is concerned with the utilization of these scientific principles in practical devices and systems.

Applied physicists can also be interested in the use of physics for scientific research. For instance, the field of accelerator physics can contribute to research in theoretical physics by enabling design and construction of high-energy colliders.

Applied Physics Laboratory

The Johns Hopkins University Applied Physics Laboratory (APL), located in Howard County, Maryland, near Laurel and Columbia, is a not-for-profit, university-affiliated research center employing 5,300 people. APL is primarily a defense contractor. It serves as a technical resource for the Department of Defense, NASA, and other government agencies. The Lab is an engineering research and development organization rather than an academic division of Johns Hopkins University. Hopkins’ Whiting School of Engineering offers part-time graduate programs through its Engineering for Professionals program. Courses are taught at seven locations in the Baltimore-Washington metropolitan area, including the APL Education Center.

History

APL was created in 1942 during World War II under the Office of Scientific Research and Development as part of the Government’s effort to mobilize the nation’s science and engineering expertise within its universities. Its founding director was Merle Anthony Tuve. The Laboratory succeeded in developing the variable-time proximity fuze that played a significant role in the Allied victory. In response to the fuze's success, the APL created the MK 57 gun director in 1944. Pleased with the APL's work, the Navy then tasked it with the mission to find a way to negate guided missile threats. From there on, the APL became very involved in wartime research. Expected to disband at the end of the war, APL instead became heavily involved in the development of guided missile technology for the Navy. At governmental request, the University continued to maintain the Laboratory as a public service.

Johns Hopkins University

The Johns Hopkins University (commonly referred to as Johns Hopkins, JHU, or simply Hopkins) is a private research university in Baltimore, Maryland. Founded in 1876, the university was named after its first benefactor, the American entrepreneur, abolitionist, and philanthropist Johns Hopkins. His $7 million bequest—of which half financed the establishment of The Johns Hopkins Hospital—was the largest philanthropic gift in the history of the United States at the time.Daniel Coit Gilman, who was inaugurated as the institution's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research. Adopting the concept of a graduate school from Germany's ancient Heidelberg University, Johns Hopkins University is considered the first research university in the United States.

Johns Hopkins is organized into ten divisions on campuses in Maryland and Washington, D.C. with international centers in Italy, China, and Singapore. The two undergraduate divisions, the Krieger School of Arts and Sciences and the Whiting School of Engineering, are located on the Homewood campus in Baltimore's Charles Village neighborhood. The medical school, the nursing school, and the Bloomberg School of Public Health are located on the Medical Institutions campus in East Baltimore. The university also consists of the Peabody Institute, the Applied Physics Laboratory, the Paul H. Nitze School of Advanced International Studies, the education school, the Carey Business School, and various other facilities.

New Horizons

New Horizons is an interplanetary space probe that was launched as a part of NASA's New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory (APL) and the Southwest Research Institute (SwRI), with a team led by S. Alan Stern, the spacecraft was launched with the primary mission to perform a flyby study of the Pluto system, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs).

On January 19, 2006, New Horizons was launched from Cape Canaveral Air Force Station directly into an Earth-and-solar escape trajectory with a speed of about 16.26 kilometers per second (58,536 km/h; 36,373 mph). After a brief encounter with asteroid 132524 APL, New Horizons proceeded to Jupiter, making its closest approach on February 28, 2007, at a distance of 2.3 million kilometers (1.4 million miles). The Jupiter flyby provided a gravity assist that increased New Horizons' speed; the flyby also enabled a general test of New Horizons' scientific capabilities, returning data about the planet's atmosphere, moons, and magnetosphere.
