Non-Euclidean Geometry: Understanding the World Beyond Euclid’s Framework When one thinks of Geometry, the first name that comes to mind is often Euclid, the father of geometry. His book, “Elements”, laid the foundation for thousands of years of mathematical studies and set the standard for what was considered “true” geometry. However, in the 19th century, a breakthrough in the field of mathematics challenged Euclid’s previously undisputed theories and gave birth to the revolutionary concept known as Non-Euclidean geometry.
