Why was I so nervous? I’d spoken in hundreds of seminars and classes, in front of large audiences, and even politicians and lawmakers. So, why was I clammy and pacing?

Admittedly, I’d never explained my research to a crowd of nonscientists relaxing over food and drink at a local tavern. Was I afraid the audience might oppose genetically modified organisms? Or question the environmental risks of recombinant DNA?

It was 2016 and I was hosting one of the first science caf茅s for the Rockville Science Center, a nonprofit I’d established with a group of interested citizens and a local chapter of the research honor society, Sigma Xi.

With biotechnology booming and many major government labs nearby, we thought Rockville, Maryland was the ideal location for a center focused on explaining science to the public. We wanted to put on science presentations in the style of Ben Wiehe.

Wiehe now heads the , but back in the day, he worked at Boston’s public TV station and pioneered the concept of science caf茅s. He used to walk into Boston bars and start talking about all things science. No slides, no flip charts, just conversation. And that’s what we wanted to do: share science in bars, restaurants, community centers — anywhere.

I was the inaugural leader, giving the first presentation to a packed crowd.

As soon as I started chatting about the research in our university biotechnology institute, I realized my anxiety was unfounded. Everyone paid rapt attention. Although my presentation lasted only 10 minutes, the audience questions kept me under the spotlight for over an hour.

The audience was more receptive to technology than opposed. It was really quite inspiring. A few questions pertained to translating basic science into cures and therapies: How long does it take? How much does it cost? How complicated is it? Parents asked how their children could learn how to do science that makes a difference. Some asked what the students we trained went on to do. And a couple of people asked about risk, compliance with regulations, and safety. But really not too many.

Afterward, more than a few people offered to buy me a drink to continue the conversation.

That science caf茅 allowed me to connect with the public and communicate all types of science. I’ve done more than a handful since, but I’ll never forget my first. You should host one too; it’s a great experience — for everyone.
