The Nuclear Princeton project innovates interdisciplinary, self-reflexive, and decolonial approaches in the social sciences and humanities by connecting teaching, research, and student activism. By centering on thus far silenced Native perspectives on science and technology, the project explores Princeton's legacies in nuclear science and technology and its ongoing roles in making the world irreversibly radioactive. In doing so, the project invites Princeton faculty, staff, and students to reckon with our collective responsibility for the long-term environmental effects of the current practice of science and technology "in the Nation's Service and the Service of Humanity." The project uses diverse visualization technologies, including but not limited to a web-based GIS platform, "re: earth, animation, and data physicalization to make the invisible legacies of nuclear materials visible and tangible.
