Newton
The anecdote of the apple we learn from Voltaire， who had it from Newton’s favourite niece， who with her husband lived and kept house for him all his later life. It is very like one of those anecdotes which are easily invented and believed in，1 and very often turn out2 on scrutiny to have no foundation.3 Fortunately this anecdote is well authenticated， and moreover is intrinsically probable； I say fortunately， because it is always painful to have to give up4 these child-learnt anecdotes，....This anecdote of the apple we need not resign. The tree was blown down in 1820 and part of its wood is preserved.
— O. J. Lodge
scrutiny n. 细察
foundation n. 根据
authenticate v. 证明……是真的
intrinsically adv. 本质上
probable adj. 很可能发生的
preserve v. 保存，保留
中译 苹果趣事（牛顿）
这件有关苹果的轶事，我们是从伏尔泰那儿听来的，他又是从牛顿钟爱的侄女那儿听来的。这位侄女和她的丈夫陪伴牛顿度过晚年，并且替他料理家务。这件趣事极似那些随意编造而且人们信以为真、可是一旦追根问底却是毫无根据的轶闻故事。幸而这则趣事的可靠性是经过证实的，而且就其本身而言也是可能发生的。我之所以用“幸而”这个词，是因为这些孩提时期就听到的轶闻趣事，最后不得不割爱，总是令人心痛……这则苹果的趣闻，我们不必抛弃。那株苹果树在1820 年被风刮倒，而一部分树干还保留至今。
——〔英〕洛奇
