‘The sublunar world’ explores how the early modern view of the world moved on from Aristotle's teachings. Nicholas Steno found that layers of rock provided information about the earth's history. Gilbert elucidated the idea of Earth having magnetic poles. Galileo reduced the world to mathematical concepts, paving the way for a new form of physics. Torricelli found that air had weight, which directly contradicted Aristotle. Alchemy was not popular in academic circles at the time, but alchemists postulated a mechanical philosophy involving the interaction of particles (or atoms). Whilst Aristotle's ideas were challenged throughout this time, many scholars attempted to update his ideas rather than abandon them.
