Instead, an observer would find Dr. Cale’s assistants moving between the machines, most of them wearing T-shirts or tank tops and jeans, a few with dirty white lab coats thrown over the top, as if to say, “I’m working in an indoor farm, but I’m still a scientist; I will always be a scientist.” The number of lab coats had dwindled even in the weeks since I’d come to the factory, as people realized that maybe some trappings of the old world were less important to hang on to than others.
What's this with the lab coats? Scientists don't care about lab coats anywhere near as much as nonscientists apparently think they do.
