A320rider, don't you mean a physicist? I fail to see why a medical practitioner such as a physician would have an advantage in the ATPL's.
Oreo, having done an Undergraduate degree in Engineering, and pursuing a Doctorate degree in Applied Physics, I can honestly say you really don't need to go to these extents to be able to complete the ATPL's.
I personally have not done the ATPL's (yet), but I've seen some of the material and exams papers, and the level of maths and physics ability is not that high.
I'm not sure where you're from. If its UK, then I'd say good passes at AS-Level maths and physics would suffice. If you're not at that level yet, don't fret, its nothing sitting down with a few maths and physics books and some self-study can't put right.
Oh yeah Oreo, take everyone's advice and ignore A320rider. I think he's having a rough time of it in the aviation industry at the minute!
I wish you the best of luck Oreo.
