Why do people sing about science? Science songs can be used as educational tool, but sometimes a science song has a different purpose. Singing about science can generate a sense of community, to build a connection with other scientists and science fans. In 2011, scientists widely shared a YouTube video of the Zheng lab at Baylor College of Medicine performing a science-themed parody of a Lady Gaga song. It was popular not just for the impressive performance and the well-known melody, but because it described familiar situations for anyone working in a biomedical lab. This sense of community building through STEM music is a bit like "filk" – a style of music originating at science fiction conventions, where fans create songs about their favourite sci-fi and fantasy universes. To what extent science songs and filk music overlap is a matter of debate, but comparing the filk and science songs communities may give us a better sense of the cultural role of science music.
