The Opposite of Five
An excellent and most interesting question reader.
The number five predates any number, coming before six, seven and even one. Five was invented shortly after the invention of the number one however at this stage the number system was of no use as the then five numbers of two, three, four and five did not make any sense without the introduction of the number one. Number one was invented of course by Pythagoras in 121 BC - a great achievement for man kind. Four of course came before five but this does not necessarily answer the question of 'what is the opposite of five?'
Let us look at this problem in a different light; find you're nearest electrical retailer and buy an ultraviolet lamp. Switch it on and point it at the question; 'What is the opposite of five?' Does this help? If not, read on.
A close encounter of the opposite of five was encountered in laborotories in Cambridge University in 1997. Researchers there discovered that by turning the number five upside down, caused the number five to become number 2. However it was later argued that they're research was flawed because the angle of the second line going down from the number two was not in fact the correct angle when encountered by a number five.
