The thoughtful reader might propose the charge of the electron as an obvious candidate for the third natural unit.

善于动脑筋的读者，可能提出电子的电荷作为第三个自然单位的明显的候选者。

There are some basic physical properties ofthe universe, such as the charge of the electron, the precise strength ofgravity, the speed of light, etc.

宇宙有一些基本的物理性质，比如电子的带电性、重力的精确大小、光速，等等。

We said that that second electron was so far out of the picture, that it had absolutely no affect on what the charge was felt by that first electron.

我们说第二个电子远离这张图片，这样它就彻底的对，第一个电子感觉到的电荷没有影响了，所以。

youdao

And let's say our second electron now is really far away, such that it's actually not going to shield any of the nuclear charge at all from that first electron.

距离原子核非常非常近,我们说第二个电子处于非常远的位置,这样它不会对第一个电子,感受到的来自原子核的电荷量有任何屏蔽作用,我们最后要说的是。

Again we have the charge of the nucleus on plus 2, +2 but let's say this time the electron now is going to be very, very close to the nucleus.

对于我们的氦原子，我们有一次得到了原子核电荷量为,但是我们说这次电子。

What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.

前人们所做的就是他们说让我们确定,一个能量单位用来代表一单位电荷,加速穿过形成的一单位电势差，我们叫它电子伏特。

Has the charge of the electron or the speed of light altered over time, or has some combination of effects occurred?

ECONOMIST: Fundamental physics

His main characters include G, the strength of gravity, h, Planck's constant, which governs the quantum nature of reality at small scales, e, the charge of the electron, and c, the speed of light itself.

ECONOMIST: Modern physics

The physicist Robert Millikan (who showed minor confirmation bias in his own work on the charge of the electron by omitting outlying observations that did not fit his hypothesis) devoted more than 10 years to trying to disprove Einstein's theory that light consists of particles (photons).
