Friday, 13th - Are you feeling superstitious?

According to folklorists, there is no written evidence for a "Friday the 13th" superstition before the 19th century.The earliest known documented reference in English occurs in Henry Edwards' 1869 biography of Gioachino Rossini.
Consequently, several theories have been proposed about the origin of the Friday the 13th superstition.
One theory states that it is a modern amalgamation of two older superstitions: that thirteen is an unlucky number and that Friday is an unlucky day.
In numerology, the number twelve is considered the number of completeness, as reflected in the twelve months of the year, twelve hours of the clock, twelve Gods of Olympus, twelve tribes of Israel, twelve Apostles of Jesus, the 12 successors of Muhammad in Shia Islam, whereas the number thirteen was considered irregular, transgressing this completeness. There is also a superstition, thought by some to derive from the Last Supper, that having thirteen people seated at a table will result in the death of one of the diners.
Friday has been considered an unlucky day at least since the 14th century's The Canterbury Tales, and many other professions have regarded Friday as an unlucky day to undertake journeys, begin new projects or deploy releases in production. Black Friday has been associated with stock market crashes and other disasters since the 1800s.
If you are spooked by Friday the 13th, you're in for a whammy of a year. This  unlucky day is the second of three for 2012. Many superstitions stem from the same human trait that causes us to believe in monsters and ghosts: When our brains can't explain something, we make stuff up. In fact, a 2010 study found that superstitions can sometimes work, because believing in something can improve performance on a task.
If you're not scared of Friday the 13th, you should be scared of the word used to describe those who are: friggatriskaidekaphobics. (An alternative, though just as tongue-twisty, word for the fear is "paraskevidekatriaphobia.")
For a superstition, Friday has long been considered an unlucky day - according to Christian tradition, Jesus died on a Friday.
According to the Stress Management Center and Phobia Institute in the USA, about 17 million people fear Friday the 13th. Many may fall prey to the human mind's desire to associate thoughts and symbols with events.
"If anything bad happens to you on Friday the 13th, the two will be forever associated in your mind," psychologists say. "All those uneventful days in which the 13th fell on a Friday will be ignored."

The Marshmallow Challenge

Tom Wujec from Autodesk presents some surprisingly deep research into the "marshmallow problem" -- a simple team-building exercise that involves dry spaghetti, one yard of tape and a marshmallow. Who can build the tallest tower with these ingredients? And why does a surprising group always beat the average?
