Perhaps my best (or possibly worst) quality is that I'm eternally dissatisfied with my very own expertise.
This might be why I have actually revealed a specific skill for maths as well as physics. Merely knowing is never good enough for me; I need to at least aim to rigorously understand the reasoning behind the mathematics I do, then, take my knowledge to its limits. Asking excessively why something is the way it is, probably to the annoyance of my lecturers, is something I'm compelled to do. I, in addition to many others, consider this Socratic technique of understanding as well as teaching to be extremely beneficial in developing a fundamental understanding of mathematics and physics from standard principles, as well as I endeavour to enlighten in exactly this fashion.
I hope I could encourage students with my extreme love of mathematics and physics or, at least, expose the topics as far much less complicated than they show up. Naturally not everybody is a mathematician, and various minds learn at various rates, nevertheless I will aim to leave an enduring and valuable impression.
