About This Book
natural-philosophyastronomyphilosophy
Why does the sun look enormous at the horizon but shrink as it climbs into the sky? Pierre Gassendi breaks down this classic optical illusion by treating light as a stream of physical particles striking the retina. You will discover how the mechanics of your own eyes determine the boundaries of the visible world.
