It is truly an honor to stand before you today, filled with immense gratitude and inspiration from this remarkable summer school. Jointly organized by Shanghai Jiao Tong University and the Tsung-Dao Lee Institute, this experience has been nothing short of eye-opening.
Reflecting on my time here, I arrived in Shanghai brimming with curiosity and enthusiasm. As I prepare to leave, I carry so much more: a profound deepening of my understanding of physics, crystallized goals for my research and studies, and friendships that I believe will endure.

Throughout these past weeks, we've explored the cutting edge of physics, significantly broadening our academic horizons. Yet, beyond the knowledge itself, one insight about the spirit of our field struck me deeply. Professor A.Z.'s statement, "We are physicists, not mathematicians," might sound radical at first. But its essence resonates powerfully: our primary task is to grasp the clear physical picture within complex phenomena, before reaching for mathematical tools.
Indeed, sometimes, in our pursuit, we risk losing sight of this seemingly simple principle. It's easy, especially as students navigating complex theories, to become fixated on the intricate mathematics – the equations and symbols themselves – and prioritize deciphering them above uncovering the core physics concepts they represent. Physics, after all, isn't merely about memorizing formulas or solving problems. As Dirac reminded us by seeking inspiration in the Poisson bracket, it's about cultivating physical intuition and building clear conceptual frameworks to truly understand our universe.

Equally invaluable has been the opportunity to connect with peers from such diverse backgrounds. I was amazed, for instance, when I asked about differential geometry, and someone immediately responded, sparking an active and insightful discussion. And at the dinner table, everyone talked about their scientific research plans and ideals. In countless conversations, collaborative projects, and shared moments, I've witnessed extraordinary qualities in all of you: unwavering dedication, innovative thinking, and a genuine spirit of collaboration. The wisdom of the old saying, “When I walk along with two others, they may serve me as my teachers,” rings true. Meeting such a passionate and exceptional group of friends loving physics has been a gift, and I am constantly learning from your strengths.

Naturally, my deepest appreciation goes to SJTU and TDLI for the exceptional organization of this program. The meticulously designed curriculum, the thoughtfully planned activities, and the seamless logistics created the perfect environment for learning to thrive. Adding further richness, beyond the classroom, the cultural experiences and explorations of Shanghai allowed us to appreciate this city's vibrant beauty and rich heritage.

Now, as this incredible journey concludes, I depart not only with new knowledge but with a transformed perspective on what it means to pursue physics. This experience has solidified my commitment to scientific research. It has equipped me with new tools – like the exciting potential of AI for science – and, more importantly, reignited the inspiration to strive for meaningful contributions to our field.

To my fellow participants: Let's cherish the connections we've forged. As we embark on our individual academic paths, let's continue to support and inspire one another. And to the organizers and faculty: Thank you for crafting this profoundly significant and unforgettable experience.

I am certain the seeds of knowledge, inspiration, and friendship planted here will undoubtedly grow. I am filled with confidence that many among us will go on to make significant contributions, not only to physics, but to the broader pursuit of scientific understanding.
Thank you.
