I plan to focus on Gentics, and I am just finishing my freshman physics, I haven't got to my bio or chem classes yet.. So I was wondering, how important is physics and our understanding of it, if we want to go into the field? I can do pretty decent on the tests and understand the formulas and how most things work. But when I dwelve deeper... like trying to understand magnetic constant, and most of the stuff they just give to us but don't explain, I kinda get lost. For example.. We learned that to find the force between two charged particles, you have to use the equation "(ke x q1 x q2) / r2). The book and class doesn't go into how we got ke or what ke is. So does it help a lot to try and understand stuff like that on my own, as preparation for when I get to the bio and chem classes? Edit: Didn't know how to use properly use the power sign on the forum until now.
