singularity75Fact of the Day:
A spider web weighing only once ounce is so thin, it could reach from New York to Paris.
Question of the Day:
How do houseflies manage to land on the ceiling upside down?
Think about this one...When the fly is heading for the ceiling, it's flying right side up. When it lands on the ceiling it is upside down. At some point along the way it has to flip over. But when? And Where? And How?
Scientists dispelled the prevalent theory, that the fly performed a fighter pilot-like barrel roll just prior to landing, by capturing this momentous event on film.
Freeze frames, from the high-speed cameras scientists used, proved that flies do not flip, but flop, as they land upon the ceiling. Prior to impact, the fly extends its forward legs over its head, makes contact, and uses the momentum it has gathered in flight to hoist the remainder of its body to the ceiling. Thus, the fly proves to be more of an acrobat, than of a fighter pilot practicing his maneuvers.
