Hi, I am currently a beginning engineering student. I'm thinking mechanical engineering, but nothing is really set in stone. I am trying to spend a lot of this summer exploring different aspects of engineering and actually go out and go through the entire engineering process of designing, creating, and refining something. But as I do this, I also want to explore the things that are core to engineering. I am reviewing math and physics in order to develop more of an understand to why things happen. But beyond just that, I am looking for textbooks, books, videos, any resources that I can use to explore engineering. I know that engineering is a hugely broad field, but I can't really say that I have a huge interest in a super specific aspect of it because I have no true experience yet. I am trying to understand the philosophy behind engineering along with important core aspects and concepts of engineering itself. What suggestions would you guys have for me?
