    科學之美 初中班 閃瑞澤 科學與人生活息息相關,從過去的馬燈、煤油燈,到現在的手電、電燈。從過去的土房木屋,到現在高樓大廈。從過去的騎馬騎驢到現的汽車、火車…。這一切都源于科學。愛迪生是一位大家都熟知的大發明家,他是崇尚科學的。

    他發明電燈泡的燈芯時曾用過許多材料做實驗,三千多次從未成功過一次,有人勸他放棄,堅信科學的他卻幽默地說:“我的成功就是排除了三千多種不能做燈芯的材料。”不知經過多少次的失敗,也不知為此付出了多少艱辛,他最后成功了,發明了電燈,造福了全人類。 這就是“科學之美”,這種美別有源于過人的堅持和不懈的努力,也源于對“科學”一詞的崇尚。 諾貝爾是一位家喻戶曉的偉人,它不僅是“諾貝爾獎”的創始人,還是“炸藥”的發明者。

    因為開鑿山洞靠人的雙手和鎬頭是很慢的,質量也不高,諾貝爾為此發明了一種“液體炸藥”,炸藥的出現,減少了人們的勞動強度,受到了人們的好評。但“液體炸藥”極易爆炸,在運輸的過程中,一旦遇到亂石橫生的山路就會發生爆炸的危險。為此,崇尚科學的他又開始研究固體炸藥,在研究實驗過程中他的爸爸炸斷了雙腿,弟弟被炸死。但他沒有放棄,最終在房子里點燃了新型“固體炸藥”,炸藥爆炸了,從一片廢墟中爬出了一個渾身是血的人,他就是諾貝爾,新型“固體炸藥”從此誕生了。

    這就是“科學之美”,這種源于一種不懈的冒險的精神,也源于對“科學”一詞的崇尚。 科學,是一種美,這種美源于人們不懈的努力和追求,成為一個科學家很難,但擁有一雙發現科學之美的眼睛卻很簡單。科學,是與人類密不可分,是人類進步發展必不可少的,所以,擁有一雙發現科學之美的眼睛很重要。我正努力地培育這雙慧眼,你呢?

      更重要的是,南京人民有著無限的熱情,時刻歡迎著各國朋友及嘉賓的光臨;他身手敏捷,速度極快,以快刀斬亂麻之勢,沖到最后一關,只用二十秒。科學之美700字作文要吃莊稼的。真是矛盾;實際上,早戀無罪。十六歲我們還不懂憂愁是是什么。
