The Art of the Unknown

The first major challenge was facing my own initial lack of knowledge. Suddenly, I found myself surrounded by entirely new protocols: what can be touched with gloves, what is strictly glove-free, and how to safely move items through the space. As I did not fully know how new equipment operates, getting startled when something goes off-routine is inevitable.

I remember one day working inside the glovebox. Due to simple fate and normal wear and tear, a valve unexpectedly failed—something that was bound to happen sooner or later—and the chamber began to inflate rapidly. Since I had just used an air tool inside, my mind jumped to the worst conclusion: "It was me, I ruined everything." The panic of those first few minutes was overwhelming. 

Not long after, another mishap occurred while preparing samples. Not being completely familiar with the exact structure they use here, I misplaced a component, and the final design didn't turn out as expected. Lacking a deep understanding of the architecture of the process, my mind blocked, and I couldn't find a way out or a solution on my own.

Therefore, I had to pause and shift my mindset. I learned that when these things happen, it is completely okay to feel stressed or scared. You have to give yourself permission to feel those emotions, accept them, and let them be, because they are a natural response to things you cannot control. But the biggest lesson is not to get stuck there.

Once I let those first few minutes of frustration pass, I forced myself to stay calm. I understood that the only real way out was to put pride aside, ask questions, and let myself be guided. To my surprise and relief, when I spoke with the laboratory team, we found quick solutions. It was highly enriching to discover how different professionals, each with their own way of working—some warmer, others cooler and more direct—were always willing to support me.

Nowadays, instead of freezing in front of the machines, I take the initiative. If I get startled or make a mistake, I ask myself: "What are we going to do tomorrow to feel better and lose the fear of doing things?" The answer is always the same: ask before acting, rely on my colleagues, and see every stumble as a necessary recalibration. This summer is teaching me that true scientific work isn’t about being perfect from day one, but about learning to navigate uncertainty so that the learning process stops being terrifying and becomes deeply fruitful.

    When I arrived at HZB for the International Summer Student Programme, I expected to learn about chemistry, new instruments, and research techniques. During the welcome event, each of us received a small gift bag. Inside was a sticker that read, "Science is Diverse."

    When an unexpected result opens a new research direction
    Every morning, as I step out of my room and feel the gentle Berlin sunshine on my face, I tell myself, “Today is a brand-new day.” Yet I never imagined that my research journey in Berlin, after joining HZB, would begin with an experimental result that did not go as expected.

    A Story of Baking a Crystal
    Once upon a time, I was a kid who loved doing home experiments and unravel the explanation behind everyday phenomena. This passion and curiosity helped me to land up here in Berlin to work on the growth of crystalline materials at the wonderful campus of Helmholtz-Zentrum Berlin. But unlike many other stories, mine starts with an introductory question: What makes growing crystals fun and also challenging?
