This is going to be a very specific request but I'm looking for something like The Imponderables series by David Feldman (the other books are on my TBR; currently reading the one about science) and that book by Stephen Hawking, I think it's titled Brief Answers to the Big Questions, also on my TBR
I do not want books that is targeted specifically for kids, though the aforementioned series seems like it is one, but the questions goes beyond age. That's what I'm looking for, the questions dwelling in the Goldilocks zone—not childish but also not advanced.
Thank in advance
