    力摘数论皇冠上的明珠

      就在一间仅有6平方米简陋的房间里,陈景润(见图,新华社发)攻克了世界著名数学难题“哥德巴赫猜想”中的“1+2”,让人类距离数论皇冠上的明珠“1+1”只有一步之遥。

      1933年5月,陈景润生于福建省福州市。他从小性格内向,喜欢演算数学题。高中数学老师讲的一个故事让他铭刻在心:1742年,德国数学家哥德巴赫发现,每一个大偶数都可以写成两个素数的和。但这需要给予证明,否则便只是个猜想。哥德巴赫自己至死也没解出来。200多年来,许多数学家试图证明但都没有成功。1953年,陈景润从厦门大学数学系毕业。他对数论中一系列问题的出色研究得到老一辈数学家华罗庚的重视,于是他被调到中国科学院数学研究所工作。

      自然科学的皇后是数学,数学的皇冠是数论,“哥德巴赫猜想”则是皇冠上的明珠。一个关于陈景润忘我钻研的故事广为流传:他边走路边思考,不小心碰到了路旁的大树,连忙道歉,可对方并没有反应;仔细一看才发现,自己碰到的是一棵白杨树。

      1973年,陈景润找到了一条简明的证明“哥德巴赫猜想”的道路,发表了“1+2”详细证明,在国际数学界引起轰动,被称为“陈氏定理”。世界数学大师、美国学者阿威尔称赞道:“陈景润的每一项工作,都好像是在喜马拉雅山山巅上行走?!?/p>

      在解析数论的研究领域,陈景润取得多项重大成果,获得国家自然科学奖一等奖、何梁何利基金奖、华罗庚数学奖等。1981年,陈景润当选中科院学部委员。1996年3月,在患帕金森氏综合征10多年之后,由于突发性肺炎并发症造成病情加重,陈景润终因呼吸循环衰竭逝世,终年63岁。
