While in attendance, she met Pierre Curie, a professor at the university. Marie used this "Curie electrometer" to make exact measurements of the tiny electrical changes that uranium rays caused as they passed through air. By 1898, Marie has discovered another radioactive element, known as thorium, and her husband Pierre became so intrigued by her work that he abandoned his research of crystals to assist Marie in her study of radioactivity. He has a bachelor's degree in environmental science from Worcester Polytechnic Institute and a master's degree in education from Harvard University.
