Looking for a book that’ll teach me something, but that is also not so hard to read

As the title says. I’m trying to improve my reading habits/skills and wanted to read a book that I’ll learn something through. But I don’t want it to be such heavy reading that I give up in the middle of it. I would really appreciate your guys’ help. Topics that interest me are science (I’m majoring in mechanical engineering), history, music and philosophy

Thank you! 🙂
