Silence, Speech, and Self-Censorship

Silence, Speech, and the Spaces In Between

Silence has followed me all my life, across languages, countries, and classrooms.

I grew up in Tashkent, Uzbekistan, where silence wasn’t just the absence of noise; it was a habit of survival. In a post-Soviet culture shaped by censorship and hierarchy, speaking too loudly or differently could still carry invisible consequences. The unspoken rule was simple: blend in, don’t question, don’t stand out.

When I came to the United States for college, I thought I was leaving that behind. I thought the air here, free, open, and brimming with ideas, would finally let me breathe. Instead, I learned that silence wears different masks everywhere. In American classrooms, it hides behind fear of judgment, fear of being “too much,” fear of saying the wrong thing in a room that claims to value “open dialogue.”

The irony is that higher education celebrates discourse while quietly punishing dissent. In my first philosophy class, when we read Plato’s Republic, I hesitated before disagreeing with my professor. Not because I lacked conviction, but because I could feel the tension—that moment when a woman of color raises her hand and everyone turns to see what “perspective” she’ll offer. I spoke anyway. The silence that followed said more than the words I’d just said. I realized then that silence is not always imposed from outside. Sometimes it’s internalized, a quiet calculation of belonging.

But silence isn’t always the enemy. There’s a kind that listens, that holds space for thought and reflection. In engineering, I spend hours debugging code or testing spacecraft systems in near-total quiet. That silence feels alive; it hums with purpose. But when silence turns into self-censorship, when it stops curiosity instead of nurturing it, it becomes dangerous.

At CU Boulder, I’ve learned to live between these two silences. In the Integrated Teaching and Learning Laboratory, where I work as an Engineering Support Student, I mentor others on prototyping and fabrication. It’s loud, printers whirring, students brainstorming, but within that noise is a deeper kind of listening. Some of the most important conversations I’ve had there aren’t about equations or design choices; they’re about confidence, identity, and learning to take up space in a field that wasn’t built for us.

That’s also why I mentor young women through UniSat, a satellite-building program supported by UNICEF. I’ve seen students whisper their questions at first, unsure if their curiosity belongs. Then, slowly, they begin to raise their voices, to own their knowledge. That transformation feels revolutionary every time.

Yet, even as I encourage others to speak, I’m still unlearning my own silence. I often wonder: how many brilliant ideas never leave someone’s mind because they fear being wrong, or different, or unwelcome? How many students stay quiet not out of disinterest, but out of exhaustion from navigating invisible barriers of culture, gender, or language?

In my aerospace engineering classes, discussions often orbit around technology, but rarely around the humans behind it—the politics of innovation, the ethics of exploration. I’ve started asking those questions more openly now: Who benefits from this mission? Whose voices are missing? Sometimes the room goes quiet. But that silence, I’ve realized, can also be a beginning, an opening.

The lesson I’ve learned is this: speech and silence are both essential to learning. The courage lies in knowing when to use each, when to speak for others who cannot, and when to listen so that others may rise.

For me, speaking up is not about volume; it’s about intention. It’s the quiet but steady decision to exist fully in spaces that were not designed for you. It’s the willingness to risk discomfort for truth. It’s the refusal to let inherited silence dictate the boundaries of your imagination.

Sometimes I still falter. There are days when I sit in class and choose silence again, not out of fear, but to listen deeper, to find words that matter. That, too, is a form of resistance.

When I wrote my essay “Voices” for the Buffs One Read Contest, I explored how silence shaped generations in my homeland, how we learned to survive by not being heard. That essay won the 2026 award, but more importantly, it started conversations. People came up to me after the event, telling me how my words helped them reflect on their own silence—cultural, political, personal. That was when I realized the power of voice is not in breaking silence once, but in making sure it keeps echoing.

Today, as I continue my work in quantum computing research at NIST and lead projects like Sproutnik, a lunar greenhouse system for the South Pole of the Moon, I carry that lesson with me: discovery and dialogue must grow together. Scientific progress means little if the people shaping it are too afraid to speak.

I still believe in silence, but only the kind that listens, not the kind that erases.

Speech, especially in academia, is not just expression; it’s courage in practice. It’s the act of existing out loud in systems that ask you to shrink. And if my journey has taught me anything, it’s that every time one of us dares to speak with conviction, curiosity, or compassion, the world grows a little wider.
