SftP Videos: Cosmos

More has been learned about the origin and structure of the cosmos in the last century than in the entire history of humanity. And new discoveries are made constantly, thanks to the skills of the international science community and the great technological advances that make it possible to probe the universe. Here are SftPublic lectures and conversations on leading areas of investigation.
