Does living happily requires a knowledge of physics, and the nature of the universe?

Vatican Saying 49. (PD 12) It is impossible for someone to dispel his fears about the most important matters if he doesn’t know the nature of the universe but still gives some credence to myths. So without the study of nature there is no enjoyment of pure pleasure.

Vatican Saying 72. (PD 13) There is no advantage to obtaining protection from other men so long as we are alarmed by events above or below the earth or in general by whatever happens in the boundless universe.
