2.4.2 Relativity, space, time and gravity Throughout the development of mechanics and electromagnetism the role of space and time had been clear and simple. Space and time were simply the arena within which the drama of physics was played out. Speaking metaphorically, the principal 'actors' were matter and ether/fields; space and time provided the setting but didn't get involved in the action.

Presents the most significant documents from our fourth President, James Madison. Most relate to two events in which Madison played a key role: the drafting and ratification of the Constitution (1787-8) and the introduction in the First Federal Congress of the amendments (1789) that became the Bill of Rights. Other documents relate to the freedom of religion and the burning of Washington, D.C., by the British in 1814 -- perhaps the major embarrassment of Madison's career.
