The Lab as Your Studio: 10 Hobbies for the Artistic Scientist
The Canvas in the Petri Dish
I thought “science” was rigid, logical, and colorless, while “art” was emotional and chaotic. I expected the two to be enemies. I started a hobby of growing slime molds in a petri dish. I wasn’t just observing a biological process; I was an artist, and the slime mold was my paint. I could guide its growth, creating intricate, beautiful, and living patterns. It wasn’t a sterile experiment; it was a collaboration with another life form. I realized the lab wasn’t the opposite of a studio; it was the most exciting, innovative, and beautiful studio I had ever worked in.
