Dragon's Egg

In a moving story of sacrifice and triumph, human scientists establish a relationship with intelligent lifeforms—the cheela—living on Dragon's Egg, a neutron star where one Earth hour is equivalent to hundreds of their years.

The cheela culturally evolve from savagery to the discovery of science, and for a brief time, men are their diligent teachers.
