Shirley Ann Jackson sees the unseen. She’s an expert in the invisible particles that make up everything in the universe, including you. Shirley is a theoretical physicist, a scientist who studies the subatomic world using only paper, pencils, computers and the most important tool of all: her imagination. Shirley’s passion for science blossomed during her childhood, with bumblebee experiments and go-cart races. But it’s her talent for math and her drive to succeed that have taken her career in amazing directions. Shirley uses her knowledge of electrons, neutrinos, and other particles of matter to better the lives of others–from solving important technology problems to teaching college physics to making nuclear power plants safer. A natural-born leader, Shirley has always seized opportunities and broken down racial barriers, not only for herself but for others. Strong Force is the compelling story of an African American scientist and her science. To tell this true story of courage, author Diane O’Connell drew on firsthand accounts from Shirley and her friends, family, and colleagues. How did a young bee collector grow up to be a world-renowned physicist? The life story of Shirley Ann Jackson will intrigue and inspire readers of all ages.
