The Bohr radius (a0 or rBohr) is a physical constant, approximately equal to the most probable distance between the proton and electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.2917721067×10^−11 m.
A city block is between 1⁄20 and 1⁄8 mi (80 and 200 m). In Manhattan, the measurement "block" usually refers to a north–south block, which is 1⁄20 miles or 80 meters. Someti ..more definition+
