Article: When we talk about superstitious beliefs , the beliefs associated with Friday the 13th , no doubt , deserve a special mention . In fact , such is the fear associated with this date that people just can't seem to stick to their daily routine on this day . The data from Stress Management Center and Phobia Institute suggests that somewhere around 17 to 21 million Americans are affected by the fear associated with this day , i.e. the combination of Friday and 13 . Even worse , the financial losses caused on this day amounts to as much as US$800 million every year . As we flipped through the pages of history , we realized that Friday the 13th bears the brunt of bad luck associated with number 13 , the unluckiest number , and Friday , the unluckiest day of the week . Number 13 has always been considered unlucky , mainly as a result of it being associated with various occurrences in mythology . While some associate it with the instance of Norse mythology , in which the god of joy and gladness - Balter , was killed in a dishonest manner by Loki - the god of discord and mischief , who was the 13th guest , others associate it with the Last Supper , in which the 13th guest was Judas , who betrayed Jesus to his enemies for 30 pieces of silver . Similarly , Friday has also been a sign of bad luck to many people , with incidents like Jesus being crucified on this unfaithful day , contributing to this belief . It is also widely believed that Cain killed Able on this very day of the week . The fear of Friday the 13th is known as friggatriskaidekaphobia and paraskevidekatriaphobia , the former combining the words frigga , meaning Friday , and triskaidekaphobia , meaning the phobia of number 13 . Over the period , the belief that Friday the 13th is an unlucky day has just become one of the most widely accepted superstitions , which consequently causes much blind panic and unreasonable fear in the world . Question: What is the passage mainly about? Yes or no, is the answer "The origins of Friday the 13 th"?

Maps Mashups Many people use online maps developed by Google, but not many know about the mashups of them.Working in a similar way to Green Maps, Map Mashups allows people to add icons of their own to existing maps to express a certain topic.The mashups is so called because it combines all the knowledge you could ever need.It ranges from the extremely useful, such as where all the World Heritage Sites are, to the most bizarre ,such as where America's drunkest cities are.With the mashups added to the basic Google Maps, a multi-layered map can be created.
