Hello everyone. Welcome to Introduction to In-depth solutions for Maxwell's Equations. This will be the last part of our electrodynamics and its application series. My name is Professor Seungbum Hong and to my right side, we have my teaching assistant, Melodie Glasser. So, let me introduce ourselves. I myself is a professor at KAIST and alumni of KAIST as well as visiting researcher at Argonne National Lab. Melodie Glasser is a student at KAIST. She will receive her master's thesis this year and she's also a Colorado School of Mines alumni. So, KAIST is a University in Korea and the mascot is nub-ju-gi, and you can see the symbol of the university. The location is in South Korea and you can see this red spot which is Daejeon. This is Mecca of science and engineering of South Korea, the next, we can see the table which lays out the overall structure of our lecture series. So, you can see if you're here, you're already check number one and number two and number three. Congratulations. So, the last part of our journey is named Electrodynamics In-depth solutions for Maxwell Equations. So, you will spend five more weeks with us to finish or complete the lecture series. So, Melodie. Yes. Among those four, which one is your favorite? I like the electric and magnetic fields one because it really started coming together and we can see the larger practical applications like generators, but number four is also great. So, I'm excited to go through that with you guys. Very good. What is your choice, I'm very curious? So, with that question left behind, let's see what we will cover. So, we will firstly recap what we have covered before including the scope of the first two lecture series. So, Melodie, can you tell our students what we did in the previous past two lectures? Yeah. So, what we focused on a lot was like the visualization. So, we talked about like, how can we use scalers or vectors or mapping or something to visualize our field and then we also did derivation. So, we told you a lot of mathematical and ways to come up with solutions for many different scenarios. Then, we also have taken a look at the full picture. We talked about the micro-scale forces between atoms and then we talked about the macroscale which is forces in capacitors. So, that's just in the first two lecture series and then we also did more and the third one. Exactly. We covered vector fields, scalar fields, how to visualize them. We also covered micron scale to macroscale. So, we covered multiscale physics in the previous past lectures. Now, this third lecture series, you have probably understood how magnetic fields are created by rotating current around the loop. You also were able to apply that knowledge to generators or motors that you can see on the right side of the picture. Now, we've got still more to learn. So, in the final part of our lecture series, we will get seriously into the Maxwell equations in free space and also with charges and currents as the sources. We will also cover the wave equation which will describe the fields as a function of space and time and we will have a lot more equations like the one that is written here to understand the underlying physics. Okay. So, in this part of our lecture series, we're going to cover five bullet points. Number one, the laws of induction. Number two, Maxwell's equations will be revisited with more rigorous approach and we will tell you about Maxwell's equations in free space that will include some of the concepts from relativity. We will also cover Maxwell's equations with currents and charge as the sources. Then, in the last part of our lecture, we will cover some of the features of AC circuits which is nicely combined with electrodynamics. With that, I'd like you to stay tuned with our lecture series and embark on the journey. Okay? See you.
