What should an ancient old non-mathematical fossil do when trying to understand GR? I'm reading "Gravity" by Shutz, no problem so far, but understand I need to up my game. What do you all recommend? Note: by non-mathematical, I'm not up to speed in tensors, get most of what else there is. What's next without blowing me out of the water.(adsbygoogle = window.adsbygoogle || []).push({});

Note(2), anyone wanting to know practical knowledge of the physics of sound in water in regard to tactical usages, let me know.
