Check out Sean Carroll's recent books if you want an introduction to these ideas that conveys the actual mathematical content and not just a word jumble.
Sean Carroll's content really hits the spot. Technical and mathematical enough to avoid metaphors that don't hold up to careful thought, but straightforward enough to be enjoyable even after work when my brain is fried. He's incredibly prolific too, hours of content per week that's accessible to people like me go up on his Mindscape podcast and Youtube posted lectures.
