You’ve come quite a way since the beginning of your first-semester course in College Physics. You have literally covered hundreds of years’ worth of discovery and scientific development. (At times it may have seemed like you were having to live through every one of those years!) From the beginnings of kinematics and Newton’s laws, you have worked your way up to such topics as Blackbody Radiation, an introduction to Quantum Mechanics, Atomic and Nuclear Physics, and Digital Circuitry.
It is important to keep in mind that all of the topics that we’ve covered have just been introductions to those topics, some scratching the surface just a little more than others. We hope that you have learned a lot in this introduction to Physics, and would love to hear that you’d like to learn more. Whether it involves you wanting to take another course in physics, or just wanting to know where to find a good book on a topic that interests you, or perhaps a journal that you can use to check up on current research that’s being done, your instructor will be thrilled to hear from you.
If, during an evening stroll, you notice something and you pause and think, “Hey–that’s physics, and I understand what’s going on!”, this course will have fulfilled one of its primary purposes. It is our sincere wish that your eyes have been opened just a bit wider to the wonders of the world around you. Thanks for your perseverance and patience, and good luck in your future studies.
