In 1950, the University of Pennsylvania Museum of Archaeology and Anthropology sent scholars to a site in central Turkey, about 50 miles southwest of Ankara. There they began an effort to uncover — literally and figuratively — details about the societies and cultures of the people who lived there hundreds to thousands of years before.
PHILADELPHIA — The field of metamaterials involves augmenting materials with specially designed patterns, enabling those materials to manipulate electromagnetic waves and fields in previously impossible ways. Now, researchers from the University of Pennsylvania have come up with a theory for moving this phenomenon onto the quantum scale, laying out blueprints for materials where electrons have nearly zero effective mass.
Such materials could make for faster circuits with novel properties.
PHILADELPHIA — Learning calculus is no easy feat. But beginning next month, the University of Pennsylvania’s Robert Ghrist will use a new, visually stimulating approach to engage tens of thousands of students in the task with a massive open online course, or MOOC, offered through Coursera’s online platform.
