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 twip (abbreviating "twentieth of a point", "twentieth of an inch point") is a typographical measurement, defined as 1/20 of a typographical point. One twip is 1/1440 inch o ..more definition+
