I've heard time and again on this forum that in order to understand Physics, wannabes and newbies need to bite the bullet, learn math, and go to University. I've taken it to heart and am in the process of doing just that. Since I'm in my 40's and I'm entrenched in an existing career and lifestyle, I'm trying to make the transition as smooth as possible. My plan, if it shakes out, is to earn an undergrad from The Open University (http://www.open.ac.uk) in the next 6-8 years. Then I would like to have the option to go after a post-graduate degree at (most likely) a bricks and mortar school in the US. I consulted with a two PhDs I know about this plan and they gave it a thumbs-up. But I'm interested in feedback from this community as well. There's also a little bit of a hiccup in my plan already. The OU doesn't offer Mathematics degrees to students residing in the US. My first choice for a degree was a BSc Mathematics and Physics as it seemed like the most serious minded course of study for someone with an interest in Theoretical Physics. The next best option for me available from OU would be a BSc Natural Science. If anyone has thoughts about the outlook of a Natural Science undergrad in terms of how it will effect trying to get to the next level (a postgraduate degree), I would appreciate it. Thank you!
