A history of telescopes
SCIENCE is frequently beautiful. But often, that beauty is familiar only to its practitioners. The physical sciences, especially, tend to reveal their charms only to those who can speak the spare and elegant language of higher mathematics in which they are conducted. Astronomy is one notable exception. Away from the light pollution of the cities, the night sky is a gorgeous sight in its own right. Training a telescope on it can produce scientifically valuable data. But it also dramatically amplifies the aesthetic experience.
