Greetings everyone! Without wasting any time, I would like to ask for a a piece of advice. I graduated a couple of years ago with a bachelor in biology. Immediately, I stepped into teaching elementary or primary science at some schools. And since science isn't all about biology only, I've came across some physics topics (elementary physics topics like the gravity, electricity...). As odd and as lame as it might sound, a never felt interest gradually took over. I let this interest freely control my life, so I'd find myself reading physics books (not university level books) and browsing through the internet for physics phenomena, just as I am doing now. Anyway, I've made a decent amount of money over the past 2 years from teaching, enough money that will allow me to comfortably pursue my graduate studies. Now initially, I looked to this interest in physics as a mere say 'hobby' just as a sales promoter would watch boxing matches, but still at times envisions himself in the ring throwing'em jabs and hooks. I actually started envisioning myself studying physics and exploring this field hungrily. Lately, I've been seriously thinking about my chances in studying physics and I'm at the verge of deciding what I should be studying. Assuming we neglect the waste of time and money and that we neglect the possibilities of me blowing off decent opportunities I might meet if I will have continued grad studies in my current field, do you think a person with no undergraduate physics or maths knowledge, like myself, could jump into a graduate physics program and pull it off? Now I'm not talking about my chances of getting acceptance into the program as I already know the answers for that. Or, do you think I should rather take an unusual step by going back to undergrad school and start studying physics from zero? Appreciate your opinions.
