Last week, Caltech's Feynman Lecture Hall was transformed into a modern-day Greek theatre. Actors moved all around the space with fervor, portraying the life story of Chien-Shiung Wu, an American experimental physicist who, in the 1950s, famously proved that parity, a type of symmetry in particle physics, is not conserved—a finding that opened the door to a better understanding of why there is more matter than antimatter in the universe.

Now in its 13th year, the festival solicits submissions by playwrights from the Los Angeles community and pairs the writers with scientists from Caltech and JPL (which Caltech manages for NASA). "We bring together dedicated writers who are passionate about exploring complex scientific ideas," says Brian Brophy, director of TACIT.…
