    The enormous steel ball you see in the photos (and the incredible video below) is the world’s largest ‘tuned mass damper’ and sits near the top of the world’s largest completed skyscraper on earth, taipei 101 in taiwan. the idea behind a tuned mass damper is quite simple: as a building sways (resulting from high winds, earthquakes etc), its tuned mass damper, essentially a finely tuned and ridiculously heavy pendulum, will move in opposition to the structure’s oscillations and minimise any movement. if that makes no sense, watch the crude gif below.

    due to both the immense size of taipei 101 and the fact that it sits just over 600ft from a major fault line, engineers had no choice but to install one of this size at a cost of $4m. too heavy to be lifted by crane, the damper was assembled on site and hangs through 4 floors of the skyscraper. it can reduce the building’s movement by up to 40%.

    What happens if they forget to grease it?:eek:
    At Coretta Scott King's funeral in early 2006, Ethel Kennedy, the widow of Robert Kennedy, leaned over to him and whispered, "The torch is being passed to you." "A chill went up my spine," Obama told an aide. (Newsweek)
