In "Seeing Further: The Story of Science and the Royal Society," Bill Bryson discusses the simplicity of astronomy compared to the complexity of human sciences. He emphasizes that while astronomy deals with clear and measurable phenomena, the human sciences involve the unpredictable behaviors and interactions of people, making them more challenging to study and understand.

This distinction highlights the inherent difficulties when trying to analyze human behavior and social systems, which are influenced by a myriad of factors. Bryson's observation sheds light on the nature of scientific inquiry, illustrating how some fields, like astronomy, offer more straightforward paths to knowledge than those involving human dynamics.
