    人物事跡

    2017年9月15日,我國著名天文學家、“天眼之父”南仁東先生因病逝世,享年72歲。

    此前的23年時間里,南仁東從壯年走到暮年,把一個樸素的想法變成了國之重器,成就了中國在世界上獨一無二的項目——500米口徑球面射電望遠鏡FAST,人們習慣稱它為“中國天眼”。

    “天眼”能夠接收到137億光年以外的電磁信號,觀測范圍可達宇宙邊緣。借助這只“天眼”,科學家可以窺探星際之間互動的信息,觀測暗物質,測定黑洞質量,甚至搜尋可能存在的星外文明。

    作為世界最大的單口徑望遠鏡,FAST有望在未來10年到20年保持世界一流設備的地位。

    24年前,日本東京,國際無線電科學聯盟大會。科學家們提出,在全球電波環境繼續惡化之前,建造新一代射電望遠鏡,接收更多來自外太空的訊息。南仁東坐不住了,一把推開同事房間的門:“我們也建一個吧!”

    南仁東當時在日本國立天文臺擔任客座教授,擁有世界級別的科研條件和待遇,一天的薪水頂得上國內一年,可他卻說:“我得回國。”

    選址,論證,立項,建設。哪一步都不易。

    有人告訴他,貴州的喀斯特洼地多,能選出性價比最高的“天眼”臺址,南仁東跳上了從北京到貴州的火車。1994年到2005年,南仁東走遍了貴州大山里的上百個窩凼。亂石密布的喀斯特石山里,不少地方連路都沒有,只能從石頭縫間的灌木叢中,深一腳、淺一腳地挪過去。

    “天眼”之艱,不只有選址。

    這是一個涉及領域極其寬泛的大科學工程,天文學、力學、機械、結構、電子學、測量與控制、巖土……從紙面設計到建造運行,有著十萬八千里的距離。

    “天眼”之難,還有工程預算。

    有那么幾年時間,南仁東成了一名“推銷員”,大會小會、中國外國,逢人就推銷“天眼”項目。

    “天眼”成了南仁東傾注心血的孩子。

    功夫不負有心人,2016年9月25日,“天眼”項目正式落成啟用,習近平主席親自致信表示祝賀。這一天,中國在世界天文史上鐫刻下了新的高度。

    “南老師這20多年只做了這一件事。”他的同事和學生們說。23載,8000多個日夜,為了追逐夢想,南仁東心無旁騖,殫精竭慮,終有所成。

    23載“天眼”夢,夢圓他卻離去,但是我們相信,南仁東先生堅毅執著的科學精神和無私奉獻的高尚品格會永遠印刻在國人的心中。

    人物解讀

    一個人的夢想能有多大?大到可以直抵蒼穹。一個人的夢想能有多久?久到能夠穿越一生。

    當個人名利和報效祖國不可兼得時,南仁東用他的選擇告訴了我們何為愛國,何為奉獻;當事業面臨艱難險阻,目標看上去遙不可及時,南仁東用他的一生告訴了我們何為夢想,何為堅守。
