 It's funny, because so many people say, well, why am I going through this math? I'm not going to use this. Well, it comes up all the time. Calculus comes up all the time in the work that I do. Now that I'm not as involved in research, I actually have to find myself forgetting some things if I'm not doing it on a regular basis. But all the math that you end up learning, it totally applies to physics and the physics that I do. Plasma physics, for instance, is very important for the work that I do, because the sun is a big ball of plasma. So that is a course that I took that has just been ongoing. I use it all the time. But there's fundamental science, fundamental physics. Not only do you use the tools that you learn in these courses, but there's on a higher level, you learn how to solve problems in other areas of your life as well. When you're good at or you learn how to tackle problems in math and science, you have that ability to apply problem solving to other areas of your life. So I always tell people that even though they don't see the benefit in why are they going through learning all these things, well, you never know when it's going to come into play or when it might be beneficial. It actually comes into play in my life even outside of my work. So I think it's important. It may not always be obvious how it's going to apply or how it's going to be important, but generally, if you go into the sciences, it definitely will apply. But even if you don't, some of these tools that you learn can actually be beneficial in other things.
