第378章 历法(2 / 2)

“。。。?”胡青看着面带微笑的老师,忽然想起早上出门时爷爷脸上和蔼的笑容,一时间竟将两人的笑脸重合,不自禁的打了个寒战。

之后又陆陆续续来了二十来人,人数不到昨天的一半。闻人楚并不生气,甚至有点高兴,因为那几个基础差的学生一个都没来。

“之前我们讲了天文学的意义以及星宿的分类,今天我们讲个更加贴进我们日常生活的东西,阴阳历与节气。阴阳历在天文学中是指兼顾太阳、月亮与兽人大陆关系的一种历法。阳历年固定在365天,阴历年相比阳历年在天数上有时会相差一个月。

为了协调阳历年与阴历年之间的天数,于是产生了阴阳历。在阳历上又分了若干节令,在阴历上表现出了节令的时间,称为中气,两个合起来统称为节气。”闻人楚讲完一段,等着学生们消化。

“楚老师,据我爷爷说我们以前全年只有10个月,每个月30天,还有65天是年末的休息月。那为什么要改为现在的12个月?现在有的月是30天,有的月是31天,多麻烦呀~”胡青提问道。

闻人楚没有立刻回答,而是从包里取出一样类似折叠尺的东西,然后走到屋内大落地窗前将它打开立于地面。这才说道,“这个东西叫土圭,是一种测量日影长短的工具。大家如果感兴趣,可以在家中立一根大一点的垂直于地面的杆子,更加便于观察,观察记录的时间在每日正午。关于重新划分月份的依据就是由这根看似普通的杆子而来,它在正午时的影子长短帮我们确定了季节的变化。”

“季节变化。。。?可是兽人大陆夏天与冬天差不多长呀。。。”胡青挠挠头,他有点听不懂了。

“这好多了,我母父的外公说,他们那会只有雨季和雪季,春秋都没呢,气温可以昨天还泼水成冰,今天就在石头上摊鸡蛋!”狮族青年边说边夸张的比划。

“啊。。。?那食物还不都坏了呀。。。”

“就是坏了啊,所以过去才总是饿肚子!”

“。。。”闻人楚嘴角抽动的听着学生们讨论,心里想的却是人家怎么都到第四代第五代了,自己连第三代的影子都没看见。多凄凉啊。。。

他轻咳一声继续讲道,“过去的兽人大陆气候确实如此,季节得到区分是在几次剧烈的地壳变化之后。但是海平面上升又让季节变化没那么明显了。不过这都是暂时的。”

闻人楚干脆与一群学生一起蹲在土圭边上,指着杆子的影子讲,“一年365天,取正午时的数据,我们将圭表日影最长的这天作为冬至日,以冬至日为八个节气的起点,即冬至、立春、春分、立夏、夏至、立秋、秋分、立冬等。再细节的发现与划分要靠你们了。”

“老师,冬至土圭的影子最长,那么夏至是不是最短呀?”胡青将视线从土圭上转向闻人楚,期待的问。

“对。”这真是个会举一反三的好孩子,闻人楚心想。

“那春分秋分呢?什么意思?影子有一样长的时候嘛?”胡青觉得,今天的天文学比昨天的有意思多了。
