- Franklin Court - Independent National Historic Park (nps.gov)
Franklin Court was the site of the handsome brick home of Benjamin Franklin, who lived here while serving in the Continental Congress and the Constitutional Convention. Franklin died here in 1790; the house was torn down 22 years later. Today the site contains a steel “ghost structure” outlining the spot where Franklin’s house stood and features the Benjamin Franklin Museum, a museum that explores Franklin’s life and character through artifacts, animations, and hands-on interactives. The Franklin Court complex also includes a working reproduction of an 18th century printing office, an architectural/archeological exhibit, and an operating post office.
- Radius (Wikipedia)
In classical geometry, a radius (pl.: radii or radiuses) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel. The typical abbreviation and mathematical variable name for radius is R or r. By extension, the diameter D is defined as twice the radius
