Insects attracted to light because they think it is the Sun, or is it just that they use them as travelling reference points?
Nobody really knows for sure, but moths/Insects are thought to use the moon as a point of reference to travel in a straight line. This might help to explain why more moths seem to be attracted to artificial lights on nights when there is no moon. If moths are drawn in very close to a bright light source they may become dazzled, due to their eyes being unable to adjust quickly enough to the sudden brightness, so will circle the light instead of flying away from it.
You might imagine the inventor being someone from the Army or a policeman, but the true creator was a pizza delivery man! On July 21st, 1969, Richard Davis was delivering pizzas in Detroit when he was held up at gunpoint.
Luckily for the former marine, Davis had a gun of his own and shot two of the attackers but was hit twice himself. This incident gave him an idea for people like cops to avoid injury by wearing padding of some kind. The first prototype for the bulletproof vest was created by Davis out of a roll of nylon and the straps from his car’s seatbelt.
He went around to police stations shooting himself in the chest to demonstrate its power. Later, Davis created a second vest design using Kevlar, which is 230% stronger than nylon.
