I'm pretty sure the reason for both disciplines having the "s" at the end is because of their original Greek names.
When you bring math down to it, what is the basic operands? Addition, subtraction, multiplication, and division. Everything mathmatical is based off that, because that IS math. you may have different variables, but everything comes down to that. If you break it farther, multiplication is just addition. Now you might go into division, but division is just multiplication (if you change the equation) which ends up with addition AGAIN. What math doesn't use the basic principles of math, and then you think about it THAT IS MATH. You want to get real crazy, what does a computer do? It can't multiply or divide but it does every form of math imaginable (only addition and subtraction).
Now phycis, you have the standard theories like you just listed but those occupy a distinct set of rules outside of quantum physics. If you get down to it, there is only one set of physics, it's quantum physics. We just haven't really mapped that out enough to explain the non-sub atomic physics theories. That's the difference, you have a sub-atomic physics and then a "set" of physics that explains the non-sub atomic world. Two real main categories, one just branches off into the theories you listed.
 If you don't get my direction... Small phycis = quantum physics, large physics = the world around us. The world around us has several branches of physics now, but it's no longer a main category after Quantum Physics was created. Because it makes an entire NEW set of rules that none of physics in the "world around us" follow. Such as, two objects in the same place. Questions?
[edit2] Now technically Physics used to be multiple subjects, I'm just being a dick. However, math was always a single subject. When you can break an equation down to nothing but addition and subtraction, you really start to understand. Now I'm not saying it's practical, just that all math breaks down into those two operands. We use everything else as a form of short hand, which makes us create more complex theories. However they all follow the same rules if you broke them down.
[edit3] My bad, a processor only adds. it adds negative numbers for subtraction. Though since subtraction is the reverse of addition, it's essentially the same step. I still hold that addition and subtraction would be the root subject in Math. That is what Math is at it's base form, a singular function that can go both ways.Edited by mushroomboy - 5/10/12 at 3:00am
