以前寫過在地球上最遠的距離是當相方背對背的時侯.可是即使再遠,假如相方意志堅定,一路向前走,始終會有相遇的一天…
有個很舊的的數學問題: 兩個人每天的距離近了一半,何時彼此之間會變成零距離呢?任何距離都理論上可以除二,即是說,這兩人永遠都不能接觸對方*.
可見而不可踫是不是比最遠的距離更遠呢?
*其實數學上是可以計出這個零距離的時間,即是會有零距離的一日,不過我們不是在研究數學.
I wrote before that the fartherest distance between two people on Earth is when they stand back to back. However, regardless of how far apart that distance is, so long as they both have the will and continue to move forward, one day they’d be able to meet.
There’s an old mathmetical enigma: Two people walk every day such that they’re half as close to each other as the day before. When would they be able to share the same space? In theory, every length can be cut in half. Following this train of thought, the distance between these two people could never be zero*.
If you can see the other but can’t touch him…wouldn’t it be a farther distance than the fartherest distance?
*mathematically the time when they both occupy the same distance CAN be calculated, but we’re not in a math class, are we?
