When I think of physics I think of a more concrete science than chemistry or biology. To me, physics means studying the physical world and how different forms of energy lend themselves to it. All of the sciences I've taken so far deal with matter - whether I was dissecting it, mixing it, or studying living forms of it. But I feel like physics will be different in that I'll learn more practical ways of recognizing the nature of it. I'll be able to predict the general behavior of physical matter that I encounter regularly, and be able to explain why they behave as such.
They say every science has its place in every day life, and that's technically true. But with chemistry and biology it's easy to ignore the science-y aspects. When it's so cold outside that you see your breath, you don't automatically think about it's only visible because of the chemical reaction that occurs when the moisture from your lungs, mixed the CO2 you're breathing out, reacts with oxygen at low temperatures. When someone sneezes near you, you don't immediately start thinking about how all of the macrophages, B-lymphocytes, and T-lymphocytes that make up your immune system would work together to take down a virulent antigen. But every time I see a yo-yo, I wonder what the hell is going on. Whenever I think about space (which is a lot), I wonder just how many other laws of physics are the opposite from those on Earth besides gravity, and I think about how integral physics is to the way the part of the world that we most commonly observe functions. Maybe it's because I haven't taken a class on it yet and so don't really know anything about it yet, but physics seems like it's going to be interesting.
