Believe it or not, what physicists do every day is just an extension of what everyone does and experiences. From your first breath, you have been experimenting and interacting with the world around you.

Physics helps us understand so many phenomena. Learning physics lets us visit the outer edge of the universe as well as its tiniest corners and everything in between. Through many experiments, physicists have not only stretched our comprehension of the world, but have also helped us to understand what we can and can't do.

Welcome to this continuing adventure in physics. Part of any good adventure is not knowing exactly what will happen. I hope that at least some of what you learn will surprise you and make you think. Now that it is your turn to study physics, who knows what you might contribute!
