Oh, well. In any case, for the past year and a half, I have been studying the mathematical foundations of both Quantum Mechanics and General Relativity. Why? Because before I depart from this mortal coil, I want to have at least an inkling of what the greatest Physics and Mathematics minds of the 20th Century proposed about how this Universe functions. And not in words, but in mathematical symbols.

How am I doing? No surprise, it is very difficult. My best analogy is that of a person waking up every day and beating their head against a wall for 8 hours until one concept finally crystallizes and makes sense. Then wash and repeat. It is not like learning Mandarin Chinese, rather it is like trying to comprehend sophomore year Martian. I can understand Tensor Calculus machinations up until two indices, then my cerebrum short circuits and I reach for a Guinness (or three). And there I remain stuck right now.

The only advantage to this masochism is that if you can continue to absorb one basic concept every three days, then you know that senile dementia has not yet locked in to your cerebral hemispheres. If you might desire to trod the same rocky path, excellent introductory texts are available for free in PDF format by Googling: Liboff and Griffiths for QM, Schutz and Carroll (course notes) for GR. Don't say I didn't give you fair warning.

No need to call 'Bravo Sierra' -- those are serious books to seriously study QM and GR from, so you're on the right path. Good luck, with dedicated study you'll get something out of it. I enjoyed both topics when I studied them, but I'm glad I'm not directly in those fields.

What is "Bravo Sierra"??????
