风(四)兼花(一)

in #steempress5 years ago (edited)

继续说风,风是由于空气流动而产生的。空气流动带来什么呢?带来变化嘛。变化是一个永恒的话题,任何事物都处在不断变化之中。不管是有生命的,还是无生命的,都在变。

从科学的角度看,如何描述变化,也是一个重要的问题。从数学上来说,变化可以看成是


继续往下思考,就会问当分母趋近于零的时候,分子也趋近于零,那么零比零有意义吗?在某些情况下,倒也是有意义的,也就是


这个极限是存在的,从这里出发最终导致了微积分的发明。微积分早已成为了现代科学的重要工具,可谓变化一小步,人类一大步。

虽然变化不一定总是好的,但没有变化确是万万不能的。比如说如果没有空气流动变化,也就是没有风,这个世界会怎么样呢?至少那些借助风才能存活的生命就都完蛋了。比如说很多花,就是借助风力传粉。虽然在每年的那几个月里,花粉被风吹得到处飞,让人很烦。特别是对花粉过敏的人来说,那段时间真是不好过,但这也实在是没法的事情,大自然的规律没法改变啊。也只能忍一忍,终究就过去。

说到花,还能想到什么呢?且听下回分解。
