This is the world of physics, light and lasers, quantum technology, chemistry, materials, the Earth, oceans, weather, space, and math. People here run experiments, build instruments, model the future, and turn discoveries into things like lasers, chips, medicines, and weather warnings. There are paths for every level of training, from two-year laser and lab technicians to PhD scientists, and plenty of jobs that most people never hear about.
