So one thing that seems odd about the way we set up this model is that the voters are not evenly distributed.
有一点使我们建立此模型的假设很牵强,即是选民们不是均匀分布的
So, if I've got positive charge uniformly distributed, look at the choice. It's a brilliant experiment.

But if you think about it, it would not be surprising if the Gaussians, at least, gave us some surprising, more extreme, results, than the uniform.
但是如果你去思考,你不会惊讶高斯分布,会给我们的答案会,比均匀分布大。
If you drill down at the level of molecules you see that it's not homogeneous.
如果你深入到分子层面上,你就会发现它是不均匀的。

但是它们在宏观上,以均匀的方式融合了。
I'm the heterogeneous system, soft stuff, hard stuff, liquid stuff.
我是非均匀系统,有软的物质,硬的物质,液体物质等。
Or it could be uniform, where every value was equally probable.
还有均匀分布,每个值都有相同的可能性。
We're going to assume that consumers are evenly spread along this city.
我们假设,消费者均匀分布在这个城市中
This can't make sense because the plum pudding model says you've got uniformly distributed charge.
这是讲不通的,因为布丁模型说的是电荷在里面均匀分布。
Because, if you look at this molecule, you say that, well, the electrons are a little bit closer to the right than to the left so the charge is not uniformly distributed.
因为,你看到这分子时,因为,你看到这分子时,对更偏向右边,它的电荷一定不是均匀分布的。
And think about, what's the difference between the Gaussian and the normal?
高斯分布和均匀分布的,差别是什么?
I'm going to say that the positive charge is not uniformly distributed.
我要说,正电荷不是均匀分布的。
Because the uniform, as we've set it up here, is bounded.
因为我们在设定的时候均匀分布,是有界的。
Coffee is homogeneous, even though it's made up of many components.
咖啡是均匀的,使它是由许多不同的组分组成的。
And then I'll create this function, d1 this distribution d 1, which will, whenever I call it, give me a random, a uniformly selected value between minus and plus volatility.
然后我会创建这个函数,这个概率分布,每次我调用这个函数的时候,他会给我返回一个随机的,按照均匀分布,从正负浮动值之间选择的值。
These are so-called homo-polar molecules.
这就是所谓的均匀极化的分子。
You need toknow it's heterogeneous or homogeneous.
要知道系统是均匀的还是非均匀的。

You're going to have to know when you describe the system, if your system is homogeneous, like your coffee with milk in it, or heterogeneous like water with an ice cube in it So heterogeneous means that you've got different phases in your system.
你要知道,当你描述一个系统时,你的系统是均匀的呢,像掺了牛奶的咖啡,那样还是非均匀的,像放了冰块的水,非均匀系统就是说,在你的系统中有不同的相存在。
