#科普#量子物理(5)
我随身带的kindle是由原子构成的,

<img class="alignnone size-full wp-image-21731" src="http://cnstm.oss-cn-shenzhen.aliyuncs.com/2019/10/IMG_20191018_205839.jpg" alt="" width="739" height="861" /><br/>

原子是由电子和原子核构成的,电子围绕原子核转啊转,原子核是由中子和质子组成的。默里·盖尔曼发现中子和质子是由夸克组成的。目前人类极限拆分水平到最小单位是夸克。谁下一个再能拆,保证诺贝尔奖跑不掉。

世界上所有物质基本上都是由夸克和电子所构成。

&nbsp;
<blockquote>三十辐,共一毂,当其无,有车之用。埏埴以为器,当其无,有器之用。凿户牖以为室,当其无,有室之用。故有之以为利,无之以为用。
</blockquote>
——《道德经》

这段意思是空也有其作用,强调了空的重要性。

&nbsp;

原子内部是真的叫一个空。

一个原子我们来把它想象成一幢9000平方米大别墅,中间的原子核往大里说大概只有一个网球那么大,而围绕它转悠的电子大概就绣花针的针尖那么小(只有更小的可能)。原子的空旷率比最纯的黄金99.999%还要空,空到99.999999999999%

&nbsp;

看上去那么实在,敲上去硬硬的kindle组织结构是很空的,不是紧实的,所有的物质是很空的,沙发也是很空的。那为啥我一屁股也没坐穿沙发坐穿地球,这是力在发挥作用。

&nbsp;

大自然有4力,分别是引力、电磁力、强和弱相互力。

&nbsp;

天体运转、苹果坠落都是引力起作用。而克服引力你只要把苹果捡起来放桌上就行。

&nbsp;

电磁力可以用吸铁石做参考,吸铁石的吸力能够克服引力。中间传递的电磁力(由光和电产生出的力)要比引力大n百万倍。

沙发坐不穿是因为我也是原子构成的,沙发皮面原子壳上的和我的负电荷相斥。

而我的负电荷与沙发的负电荷相斥,我才会有我是坐在沙发上了的认知。

实际上我没有坐在沙发上,我离沙发有一埃7的距离。
<blockquote>71埃=10(右上角-10)米
</blockquote>
&nbsp;

你把二正极吸铁石或二负极铁石使劲捏一起,闭上眼感觉一下它们,会感觉出两块吸铁石中间总是有什么隔开它们的。这个感觉就是电磁力造成的。这个和我知道我是坐在沙发上了的感觉是一样的道理。

你那里天气如何?你好!家中可愛的寵物照想要跟大家分享嗎?或是出去玩拍到一些可愛的動物,別忘了到@dpet分享,可以得到@dpet的獎勵喔!倘若你想让我隐形,请回复“取消”。
