It was the best show ever. I saw a variety of aircraft, but the most unforgettable one was the Thunderbirds. Their flying skills were absolutely breathtaking and the powerful roar of their engines slicing through the air made my heart race. After the show, overwhelmed with emotion, I bought a souvenir T-shirt with the Thunderbirds on it. It was the most meaningful and worthwhile purchase I’ve made since coming to the U.S.

Unfortunately, I didn’t get to meet anyone new this week. But I had a great time with the lab members. Nathan, Zahir, Yehyun and I went out to grab some amazing tacos and explore downtown. With Zahir’s help, ordering was much easier and the pork taco he recommended was absolutely incredible. It was so good that I honestly felt like I could die happy after eating it! Even after we left, I couldn’t stop thinking about having another one.

I saw people at the airshow talking with those next to them and enjoying the show together. In Korea, people usually talk only with friends or family they come with. But seeing people openly share their thoughts and laugh together, even with strangers, made the show even more exciting for me. The overall atmosphere felt warmer and more lively because of that and I really liked it.

I thought I was a very outgoing person who liked spending time outside with others. But it turns out that I'm not as extroverted as I believed. There are still so many places in Las Vegas I haven’t visited, things I haven’t seen, and experiences I haven’t had. As I look back on these past three months which feel short yet somehow long, I’ve been thinking a lot about what I’ve done, what I’ve gained, and how I should spend my last month here so that I won’t have any regrets.

I learned fuzzy control. Fuzzy control is a control method that processes input values not as precise numbers, but as ranges between 0 and 1. The fuzzy input values are processed through these rules to determine the control output. This allows for stable control even in uncertain or ambiguous situations.
I also learned that it's possible to design a circuit for PID control using op-amps. In one of my major courses, I built differentiator and integrator circuits using op-amps and observed how the output signal changed in response to the input signal. Now, I’m planning to use these characteristics to build a PID control circuit for a motor, and I’m really looking forward to it because it seems like it’ll be very fun.
