张衡(78-139),字平子,南阳西鄂(今河南南阳县石桥镇)人。他是我国东汉时期伟大的天文学家,为我国天文学的发展作出了不可磨灭的贡献;在数学、地理、绘画和文学等方面,张衡也表现出了非凡的才能和广博的学识。儿时的张衡天资聪明,态度谦虚,特别喜欢思考问题。他对自然界中的万事万物都充满了兴趣。早上带着露珠的花朵,中午高悬天空的太阳,晚上天空中皎洁的月亮、一闪一闪的星星都让他产生了无穷无尽的联想。他总是跟在父母身后问这问那。

有一次,他和母亲一起到田野中挖野菜。出去的时候,太阳刚刚从东方升起,红艳艳的,煞是可爱。他不经意间看见了自己的影子是那么长。他想,我要是长得像影子那样高大多好哇。不知不觉到了中午,母亲挖了满满一篮子野菜。他跟在母亲后面,一蹦一跳地走着。“咦!影子哪里去了呢?”他惊奇地叫道。低头一看,影子缩成了一团,踩在脚底下。张衡赶忙问母亲这是怎么回事,母亲说这是由于中午到了,太阳升得最高,影子就会变短缩成一团,到了傍晚太阳快要落山的时候,影子还会变长的。

回到家里,张衡一直关注着自己的影子的长度。他发现真的像母亲说的那样:傍晚时分,自己的影子又变得像早晨时那样长。他感觉自己又学到了一点新知识,高兴极了。

一个夏天的晚上,父母带着小张衡一起到打谷场上纳凉。这是人们一天当中最快乐的时光。大人们一边摇着扇子,一边海阔天空地聊天;孩子们则叽叽喳喳地玩得不亦乐乎,一会儿捉迷藏,一会儿过家家。只有张衡一个人不声不响地呆在旁边,望着茫??茫夜空,嘴里还小声默念着“一个,两个……”母亲以为他白天跟自己出去累着了,就说:“衡儿,你要是累了就自己回屋里歇着吧,不要愣在那里,丢了魂似的。”张衡好像没听见,依然站在那里,目不转睛地望着苍穹。

父母见他没吱声,也就不再管他。又过了好一会儿,大人们都困倦了,接二连三地回家睡觉了,他还在那里望着天空。这时,一个大点儿的孩子过来拍了拍他的肩膀,说:“咳!傻了,老瞅着天上干什么,那上边又不会掉金豆子。”张衡这才回过神来,揉一揉酸痛的脖子说:“谁指望天上掉金豆子了,我在数星星。”此语一出,大家都愣住了。“什么,什么,数星星,真新鲜,还有数星星的傻瓜。那我问你,数清了吗?”那位大哥哥问。“我还没有数完呢,不过现在己经数到一千多颗了。”

旁边的一位老爷爷插话道:“孩子呀,别数了,天上的星星是数不完的。这些星星无穷无尽,飘忽不定……”张衡却打断老爷爷的话:“才不是呢,那一片天空就只有一千多颗,只要我坚持数下去,肯定会数完的。”老爷爷被张衡的执着精神打动了,一下子不知道说什么好。

张衡的父亲赶紧过来打圆场:“不许这样跟老爷爷说话。”张衡意识到自己的不对,连忙向老爷爷道歉。但他回过头来,还是想跟父亲辩解一番。父亲早看出他的心思,就说:“衡儿,我知道你的想法,但你这样挨个数是不行的。天上的星星分布是有规律的,你要按照这些规律,把它们分成一个个星座。这样才会把它们弄清、记牢。”

小张衡点了点头,按照父亲说的去做,果然又认识了许多新的星星。 开住宿费发票【159l4l58529】林先生-微ィ訁号同步...十分钟我们一定能“服务至上”的理念为您服务,致力于打造最专业,最健康,最舒适的品牌服务

随着年龄的增长,张衡的求知欲越来越强烈。当时,各种自然灾害频繁地发生,地震带来的灾难尤为严重。它来无影去无踪,一旦发生却极具破坏力。这引起了张衡的思考。他想,能不能制造一种在地震发生后准确测定其方位的仪器,以便及时调拨物资进行救援。定下目标以后,他查阅了大量关于地震的资料,并且多次实地勘测。

有时,张衡为了获得第一手资料,亲自来到刚刚发生地震的地方,测量大地的震感。有一次,他把测震仪插入大地,刚要读取数据,一波剧烈的余震袭来,离他不远处的一道土墙轰然坍塌。幸亏他眼疾手快,往旁边一跳,才躲过一劫,不然肯定要被砸成肉泥。他拍拍身上的灰土,继续看仪器上的数据。远处的老百姓十分不理解他的做法,认为他简直是发疯了。但张衡不为所动,仍然夜以继日地研究地动仪。

不久,地动仪成功间世了。
