    數學無處不在

    編輯:作文網 | 來源:優秀作文

         數學無處不在。生活中有,故事中也有。而且這些數學往往都會有著一個數學原理、規律或邏輯。古今中外,每個數學家都是在生活中通過一次發現,實驗從而有了靈感。然后便刻苦鉆研從而發現數學原理成為數學家。
          例如祖沖之。他從小就閱讀了許多天文、數學方面的書籍,勤奮好學,刻苦實踐,終于使他成為我國古代杰出的數學家、天文學家。 祖沖之在數學上的杰出成就,是關于圓周率的計算。秦漢以前,人們以"徑一周三"做為圓周率,這就是"古率”。后來發現古率誤差太大,圓周率應是"圓徑一而周三有余",不過究竟余多少,意見不一。直到三國時期,劉徽提出了計算圓周率的科學方法--"割圓術",用圓內接正多邊形的周長來逼近圓周長。劉徽計算到圓內接96邊形, 求得π=3.14,并指出,內接正多邊形的邊數越多,所求得的π值越精確。祖沖之在前人成就的基礎上,經過刻苦鉆研,反復演算,求出π在3.1415926與3.1415927之間。并得出了π分數形式的近似值,取為約率 ,取為密率,其中取六位小數是3.141929,它是分子分母在1000以內最接近π值的分數。

       像這樣的人還有很多,他們都是從生活中刻苦鉆研從而得出數學原理的。今天,我要講一個小故事。同樣,這個故事里也蘊含著一個數學知識呢。讓我們一起來看一看吧。

       阿凡提運用他的聰明才智為人民行俠仗義,無情地嘲弄那些殘暴而又愚昧無知的封建統治者,那些老爺們對阿凡提恨之入骨。
        一天,國王召阿凡提進宮,煞有介事地對阿凡提說:“阿凡提先生,聽說你經常在外面講我的壞話,這樣吧,人們都說你很聰明,我這里有一個問題,你如果能解答出來,我就釋你無罪,如果答不出來,那就加重處罰。”原來,國王想用這個辦法作借口來報復阿凡提。國王讓人拿來了三個盒子,對阿凡提說:“這三個盒子中只有一個盒子里放著我的一粒珍珠。每個盒子上各寫著一句話,但只有一句真話,其余都是假話。你給我找出珍珠在哪個盒子里。”阿凡提一看,第一個盒子是紅色的,上面寫著:“珍珠在這里”;第二個盒子是藍色的,上面寫著:“珍珠不在紅盒子里”;第三個盒子是黃色的,上面寫著:“珍珠不在這里”。阿凡提看完了盒子上的字,略一沉思,馬上就指出了珍珠在哪個盒子里。國王和手下大臣一聽,一個個都驚訝得半天說不出話來。國王只好把阿凡提放了。
           聰明的小讀者,你能找出珍珠在哪個盒子里嗎?
          是這樣的。 如果珍珠在紅盒子中,自然珍珠便不在黃盒子中,那么紅盒子上的話和黃盒子上的話都是真話,這與“只有一句是真話”相矛盾,所以這是不可能的。如果珍珠在藍盒子中,自然珍珠就不在紅盒子和黃盒子中,那么藍盒子和黃盒子上的話也都是真話。因此,這也是不可能的。因為珍珠在三個盒子中的一個盒子里,既然不在紅盒子和藍盒子里,那么一定在黃盒子里。

      這個故事反映出的就是: 在現實生活中,任何事情都遵循一個規律,要么是這,要么是那,不可能兩者都是,這一規律叫排中律。

      結合上述,證明數學無處不在,只要大家愿意去到生活中、故事中刻苦鉆研一番,就能發現數學原理。數學是無止境的。
