The Origin of the Gravitational Constant

The gravitational constant, or at least what it represents, is a fundamental part of our universe. It represents the strength of gravity and, to our knowledge, remains unchanged throughout space and time. But how did our knowledge of this come about? It all started with the Principia, but Newton did not introduce the constant G. This video takes you through the historical process of discovering G and integrating it into the science landscape.
