Mathematicians now possess a common vocabulary for solving a wide range of problems thanks to manifolds, a concept introduced by Bernhard Riemann in the mid-19th century that fundamentally altered the way mathematicians view space. Manifolds are shapes that appear flat to an observer on a small scale, even if their overall structure is more complex. This concept transformed space from being merely a physical setting for mathematical objects into an abstract object worthy of study in its own right.

This shift in perspective enabled mathematicians to rigorously investigate higher-dimensional spaces, leading to the development of modern topology, a field dedicated to the study of mathematical spaces like manifolds. The introduction of manifolds has also significantly impacted fields such as geometry, dynamical systems, data analysis, and physics.

Before Riemann's work, space was primarily considered a backdrop for mathematical objects. However, manifolds allowed mathematicians to treat space itself as a mathematical object with its own properties and characteristics. This abstraction proved crucial for developing new mathematical tools and theories.

The impact of manifolds extends beyond pure mathematics. In physics, they are used to model the structure of spacetime in general relativity. In data analysis, they provide a framework for understanding high-dimensional data sets. Their versatility has made them indispensable across various disciplines.

Today, manifolds are a fundamental concept in mathematics, akin to the alphabet in language. Their continued study promises further advancements in our understanding of space and its applications in diverse fields.
