Phosphors radiate visible light after being energized. This means you have to expose the items to light for a while before they will glow in the dark. Phosphors then slowly release their stored energy over time. As they release the energy, they emit small amounts of light, which we see as an object glowing.
Julius Caesar (c. July 12 or 13, 100 BC to March 15, 44 BC) was a politically adept and popular leader of the Roman Republic who significantly transformed what became known as the Roman Empire by greatly expanding its geographic reach and establishing its imperial system. Allegedly a descendant of Trojan prince Aeneas, Caesar’s birth marked the beginning of a new chapter in Roman history. By age 31, Caesar had fought in several wars and become involved in Roman politics. After several alliances, he became dictator of the Roman Empire, a rule that lasted for just one year before his death.
Goal posts were originally kept on the goal lines, but after they began to interfere with play, they moved back to the end lines in 1927, where they have remained in college football ever since. The National Football League moved the goal posts up to the goal line again in 1932, then back again to the end line in 1974.
