The Lab Door That Wouldn’t Open—Until I Learned to Build a Wider One

The first time I walked into the physics lab, the room smelled like solder and dry-erase markers. Fluorescent light pooled on metal tables, turning every surface the color of winter. A few students leaned over circuit boards with the quiet confidence of people who already knew the language. I stood near the doorway with my notebook pressed against my chest, trying to look like I belonged.

I had come to college believing STEM was a meritocracy—show up, work hard, and the equations would make space for you. But that assumption began to crack the moment I realized how many small, invisible “prerequisites” existed long before anyone touched a textbook.

A Seat at the Table, and the Weight of Silence

I grew up loving puzzles: the satisfying click when a pattern resolves, the calm certainty of a correct answer. In high school, I was “the math kid”—the one teachers praised for being diligent, the one classmates asked for help before exams. Yet when I arrived on campus, I noticed something unsettling: many of the students who spoke most easily in lab already had years of exposure. They had built robots with a parent, coded since middle school, or attended summer programs I hadn’t known existed.

In my first lab group, I became the unofficial note-taker. While others debated voltage and resistance, I wrote down what they said, as if recording expertise could substitute for owning it. When I did offer an idea, I softened it with “I’m not sure, but…” as though confidence required permission.

That wasn’t just shyness—it was a learned defense. Somewhere along the way, I had absorbed the stereotype that certain people were “naturals” in STEM, and others were visitors.

The Moment I Nearly Quit

Midway through the semester, our project failed three times in a row. Each failure felt like evidence: I didn’t speak the right technical dialect, I didn’t have the right background, I didn’t have the right kind of brain. I stayed late one night after my group left, staring at our uncooperative circuit until the lines blurred.

What made it worse was how normal struggle seemed for others. They treated mistakes like weather—annoying, temporary. I treated them like verdicts. I began to wonder if I should switch majors to something “safer,” something where I wouldn’t feel like I was trespassing.

Finding the Story Behind the Science

Relief came from an unexpected place: a campus talk about widening participation in STEM. The speaker quoted a line that lodged itself in my head: STEM fields are “engines of innovation,” but they only work properly when “fuelled by a diversity of talent and perspectives” (Times Higher Education). It sounded obvious—until I realized I had been blaming myself for a structural problem.

The talk linked personal doubt to broader patterns: women and minority groups remain under-represented, and in the US and UK, women make up less than a third of STEM employees (Times Higher Education). The speaker also described practical ways doors can open—programs that welcome students without a technical background into computing through joint degrees and accessible master’s pathways (Times Higher Education). For the first time, I saw my experience not as a private failing but as a familiar barrier with a name.

Learning to Take Up Space

I returned to the lab with a different goal: not to prove I belonged, but to participate until belonging followed. I started asking blunt questions without apologizing for them. I practiced explaining my reasoning aloud, even when it was incomplete. I sought out office hours, then became the student who stayed five minutes after to clarify one last detail.

Later, I joined a peer mentoring group that paired newcomers with students who had once felt like outsiders too. Watching a mentor—someone who didn’t match the “genius” stereotype—walk confidently through a complicated problem rearranged my internal map of who STEM is for. The most powerful lesson wasn’t technical; it was human: representation doesn’t just inspire—it reduces the cost of imagining yourself in the room.

A Wider Door Than the One I Entered

Our circuit finally worked on a rainy afternoon. The LED blinked—a small, steady pulse of light—and my group cheered like we’d discovered a new planet. But what I remember most is what came after: I realized I wanted to make that moment easier for the next student hovering uncertainly in the doorway.

Now, I volunteer at outreach events and tutor intro students, especially those who think they’re “behind.” I tell them what I needed to hear: STEM doesn’t only need brilliance; it needs breadth. The future is being built in these labs, and the builders should look like the world.

Because sometimes the most important engineering isn’t in the circuit—it’s in the system that decides who gets to touch it.
