Geometry's evolution from land surveying and astronomy to modern applications in physics and digital technology is profound. It encompasses the development of analytic geometry by Descartes, the rise of non-Euclidean and projective geometries, and the use of geometric principles in art and architecture. The field's expansion into discrete and computational geometry reflects its significance in the digital age, while its influence on theoretical physics illustrates its role in understanding the universe.
