WAS THE 1969 MOON LANDING A FAKE?

On July 21, 1969, U S astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon. Even today, however, some people believe that the moon landing was an elaborate hoax that was actually staged in a secret area of the Nevada desert. There are conspiracy theories that supposedly support this claim, one such being that no footprints should have been left on the surface of the moon, as there’s no moisture there to allow the dust to clump together to form prints.

WHEN DID THE GAME ROCK, PAPER, SCISSORS BEGIN?

Rock, Paper, Scissors is a game of chance generally used to decide trivial matters between two people. Each participant shakes a fist three times, producing on the third shake either a clenched fist (Rock), an open hand (Paper) or two extended fingers (Scissors). Rock beats Scissors (because it can crush them), Paper beats Rock (because it can cover it) and Scissors beats Paper (because it can cut it). If the two players produce the same item, the game is replayed until the stalemate is broken.

However, while a CB set is what’s known as a “simplex” device (i e , two people can communicate at the same time but only one person can talk at a time), a mobile phone is described as a “duplex” device (i e , it uses one frequency for transmitting and another for receiving, enabling people on either end of the line to talk and listen simultaneously).
