Einstein's dreams - Alan Lightman

There have always been speculations about Albert Einstein getting his most inspired ideas while he was dreaming. Even though this has never been confirmed, it is true that our brain develops new connections providing insightful ideas during REM sleep, precisely when we are dreaming. Those of you who want to know more about what happens to our body and mind while we are comfortably slumbering on our beds can have a look at “Why we sleep”, a great popular science book written by Matthew Walker.
In “Einstein’s dreams” Alan Lightman, who is both a writer and a physicist, tries to figure out all the dreams that the famous Nobel prize winner could have had over the months preceding the publication of his revolutionary paper on relativity theory and specifically about the concept of time.

Life, the universe and everything - Douglas Adams

I was looking for the most famous book by the same author - The hitchhiker’s guide to the galaxy - and as I didn’t find it I left with this one instead, to see what it is about.

It’s a comic science fiction novel. I had already read some science fiction books before, even though it’s not my favorite genre, but never one of the “comic” variant. I didn’t even know it existed as a category, actually.
