The arrival of Nicolaus Copernicus into the theatre of the Renaissance marked the beginning of the decline of the "unique" human condition to and within a physical universe.
Today marks the 540th birthday of Nicolaus Copernicus (Google doodle - listed after February 19), the Polish mathematician of the early 16th century, formulator of the heliocentric model of the solar system.
This blog is named for his eponymous principle from physical cosmology: that the Earth doesn’t exist in a specially favoured position in this universe.
Its broader scientific counterpart is the mediocrity principle, which says that the state of the Earth is not a product of intent but all of it does follow rules.
Both these principles are central to the study of natural phenomena as they are and the modelling of the scientific method as it is.
