I tried to hide my embarrassment and frustration, but I’m sure my averted gaze and nervous fidgeting made it obvious that I had bad news to share.

I’d been a member of the lab for a few months but, looking at the state of the project, you might not have guessed that. Progress had been slow, and I now had to report to my mentor not only that I’d failed again to get our experiment working, but also that I’d broken over a thousand dollars-worth of equipment with one clumsy mistake. I managed to get the words out with a flimsy stoicism and prepared myself for reprimand.

He gave me a look that was somewhere between understanding and amused and said “Happens to everyone! You did good. Just fail better next time.”

The summer before my senior year of undergrad, I was combing through the course catalog, hoping to add more than quantum mechanics to my schedule, when I discovered the Department of Medical Physics at my university.

I, like so many others, had discovered medical physics by chance.

On a scorching hot, dry summer day in inland Southern California, I found myself walking into a small, dimly lit room that was situated above a bail bonds shop. The building felt like it had been there forever. The walls were lined with a myriad of playbill posters and photos from Shakespeare productions. A large bookcase was filled to the brim with worn copies of plays and books. In the center of the room were two short rows of chairs facing the far wall, where there was a small setup of two handheld cameras and chairs facing each other. I was handed a short script, told to read it only once and then wait for my turn to do a “cold read” of the scene with my partner.

For many academics, news of a one-day strike from labs and classrooms arrived just a day or two before the event itself—“probably because so few [senior faculty/administrators] are active on social media,” said Bret Eshman, a postdoctoral fellow at Florida International University. “That’s how I found out about it on Tuesday.”

The following day, June 10, protests against racial discrimination and violence entered the ivory tower, spread by Twitter hashtags like #ShutDownSTEM, #ShutDownAcademia, #BlackInTheIvory, and #Strike4BlackLives. Organized by a group of physicists, #ShutDownSTEM asked for the suspension of all non-essential work in favor of open dialogue, education, and action to eradicate anti-Black racism within research and academia.
