What are the best intro books for different science fields?

I wish to know more about science in general and books are a good way to do that. We have a good assortment of science-minded people on Tildes, so I think it would be interesting to know what everyone recommends. The one requisite is that the books must be adequate for a general audience. This means that the books must not require the reader to hold a STEM degree or even have a particular aptitude for STEM.

Just so it is abundantly clear: I am looking for books that people with an arts and humanities background can read. Laypeople. "Dummies".

I'm asking more about books that are intros to a specific field than introductions to science in general.

Thanks!
