And an electron is something where, i n fact, we might be able to, if we calculate it and see how that works out, actually observe some of its wave-like properties.
如果我们对电子做计算,并且知道如何算出来的,那么我们是可以观测到,电子的一些波动性质的。
And what we've been talking about with all of these properties are, of course, how can we figure out what that is for a certain atom by looking at the periodic table, so we want to think about the periodic trend for atomic radius.
对于我们讲过的这些性质,我们所讨论的一直都是,当然是,我们如何能够判断某一个原子的这些性质,通过观察周期表,因此我们需要思考一下原子半径的周期性规律。
A capability for asymmetric division and the production of cells that become differentiating more mature cells, those are properties of stem cells.

So it's a science that's based on macroscopic properties of matter.
所以它是一门,基于物质宏观性质的科学。
And that property could be color.
这种性质可以是颜色。
After that, we'll move on to matter as a wave, and then the Schrodinger equation, which is actually a wave equation that describes the behavior of particles by taking into account the fact that matter also has these wave-like properties.
之后,我们会转移到物质,是一种波的话题和薛定谔方程,薛定谔方程是描述粒子,在考虑物质的波动性质后,的行为的方程。
So that's asymmetrical division and that's a property of stem cells.
以上说的就是不对称分裂,是干细胞的性质之一
And there will be a little bit of history in there, but this is mostly modern chemistry and represents the basic properties of matter, and it's basic properties of all matter, including living matter, which was what really interested me, that connection between chemistry and biology.
它们都有一些历史,但都是最现代的化学,代表了物质的最基本的性质,而且是所有物质的最基本性质,包括生物,这个让我很感兴趣,因为它连接着化学和生物学。
