A piece of physicist Sir Isaac Newton's apple tree is to defy gravity by being carried into space on the next NASA shuttle mission.

　　物理学家伊萨克 牛顿爵士的那棵苹果树上的一截树枝不久将随美国宇航局的宇航员们前往太空，体验零重力。

　　The 4-inch-long wood sample, which is normally held in the Royal Society archives in London, comes from the original tree from which an apple fell and inspired Newton's theory of gravity.

　　这截4英寸长的树枝现存于伦敦皇家学会档案馆，它来自那颗激发牛顿得出万有引力定律的苹果树。
