PUBQUIZ 2009-04-30 med Steinar K.



Vinner var Pungråttan.

Dette var siste quiz for sesongen. Vi begynner på nytt til høsten.

Det er en feil i spørsmålene. Det står at det bare er mulig å brette et papir 7 ganger. Dette er en myte. for mer informasjon se http://en.wikipedia.org/wiki/Paper_folding

A popular belief holds that it is impossible to fold a sheet of paper in half more than 7 times, possibly due to the difficulty of performing even 6 folds. This belief was debunked by then high school student Britney Gallivan who successfully folded a piece of paper 12 times in "Single Direction Folding".[1] However, some argued that the folder should fold in half, turn 90 degrees, then fold in half again, rather than folding the same way.

The television series MythBusters "busted the myth" of the 7 fold limit by folding taped-together sheets in half and turning 90 degrees each time, for a total of 11 folds. The first eight folds were completed by hand, while the rest were completed using both steam rollers and fork lifts. [2][3] This was accomplished using 17 large rolls of paper taped together to form a very large yet relatively thin "sheet."

One of the reasons why high-fold-count paper folding is so difficult is that the height, and thus width of the paper required and height of the successive folds, grow exponentially. Folding a piece of paper in half 100 times, if it were possible, would produce a stack of paper approximately 8×1022 miles in height.[4]
