Convex glass lenses and bowls, for enlarging the appearance of objects, led to a scientific revolution in how one could see things that had previously been too small or too far away to be seen with the naked eye. In addition to these lenses, the microscope has thin glass surfaces on which the examined specimen can be placed. But what happens when this specimen is glass? These photographs, taken under an electron microscope, describe what happens to light as it passes through a present object hidden in space.
