時(shí)差N小時(shí):數(shù)字零的由來(lái)(上)

Did you know that the number zero was discoveredby Hindu mathematicians around the sixth century?What? That's crazy! Zero is just a number. It's notsomething that you have to discover, just there.Well, actually what I mean is … isn't it there?That's… You know what I mean. That was exactly theproblem. Sure, people had the idea of a number thatstands for nothing, but they were confused by it.For many centuries the notion of number “zero” wasdisregarded as nonsense. The whole thing actuallyfrighten people. No,kid? No.Why Aristotle himselfargued that the idea of zero should be outlawed? because when you try to divide othernumbers by zero you don’t get anywhere. Zero times infinity is still zero!

你知道“0”這個(gè)數(shù)字是由印度數(shù)學(xué)家在6世紀(jì)左右發(fā)明的嗎?什么?那太瘋狂了。“0”只是一個(gè)數(shù)字，那并不是你必須發(fā)明的，它就在那兒。是的，事實(shí)上我的意思是……它不在那兒?jiǎn)?那是……我要說(shuō)的。那正是問(wèn)題所在，當(dāng)然，人們腦中有這樣一個(gè)什么都不表示的數(shù)字概念，但是他們被這個(gè)概念搞糊涂了。許多世紀(jì)以來(lái)，零的概念被當(dāng)作胡鬧而沒(méi)人理會(huì)。零的事讓人們感到恐懼。不會(huì)吧?你在開(kāi)玩笑?我不是開(kāi)玩笑。為什么亞里士多德?tīng)?zhēng)論零的概念是不受法律的?因?yàn)楫?dāng)你用0除以任何數(shù)字時(shí)，得到的仍然是0。0乘以無(wú)限大的數(shù)字仍然是0。
