The physics of viruses /
The Physics of Viruses presents what is known about viruses from the viewpoint of a physicist. In so doing, a major aim has proved to be the description of viruses, their shape, and structure. Rather surprisingly, definite shapes and structures are emerging, and it is with a heightened sense of exci...
