So, what I'm thinking of is the universe is kind of like an atomic nucleus.

所以，我认为宇宙类似于原子核(atomic nucleus)。

Nucleon density distribution is one of the most important characters of an atomic nucleus.

核子密度分布是原子核的一个重要性质。

One Becquerel corresponds to the transformation (disintegration) of one atomic nucleus per second.

1贝可相当于每秒转换(分解)1个原子核。

We are expecting to see that it decreases because it's feeling a stronger pull, all the electrons are being pulled in closer to the nucleus, so that atomic size is going to get smaller.

我们将看到它是减小的,因为电子会感受到越来越强的吸引力，所有的电子将会被原子核拉得越来越近，所以原子半径将越来越小。

This is because even though z, the atomic number is still increasing, we are also getting further away from the nucleus.

从有效核电量方面来想一想为什么，这是因为，尽管，Z，原子序数依然在变大，但我们同时也在离原子核越来越远。

Their demon is another atomic nucleus, which interacts with the first as the demon would.

ECONOMIST: The cost of forgetting

Radioactivity is measured in Becquerels, which convey the disintegration of an atomic nucleus per second.

Other ideas include building a detector to see if the spin of an atomic nucleus can be measured, or using the technique as an ultrasensitive antenna.
