The Möbius strip is a single-sided and single-edged geometric structure frequently studied in mathematics and topology. It was first independently defined in the 19th century by German mathematicians August Ferdinand Möbius and Johann Benedict Listing. Although this strip initially appears like an ordinary strip, it is formed by rotating one end 180 degrees and joining it to the other end, and due to this property, it is considered "single-sided." The Möbius strip is not only a subject of mathematical curiosity but also a remarkable structure in art, engineering, and natural sciences.

Properties of the Möbius Strip
The Möbius strip is one of the fundamental structures for understanding surface topology. As a surface, it is one-sided; this means that if a line is drawn with a pen along the surface of the strip, the entire surface can be traversed until the line reaches its starting point. Similarly, it has only one edge. This is the key feature that distinguishes the strip from an ordinary surface.
Formation and Basic Structure
To obtain a Möbius strip, a narrow and long rectangular strip is taken. When this strip is rotated 180 degrees at one end and joined with the other end, the Möbius strip is formed. Although the resulting structure appears three-dimensional, it is actually a two-dimensional surface. The "one-sided" nature of the surface is surprising for individuals accustomed to classical geometry.
Mathematical and Physical Properties
Due to the topological property of the Möbius strip, cutting it crosswise does not yield the same results as with classical surfaces. When the strip is cut lengthwise down the middle, the resulting structure is still a strip, but this strip is no longer single-sided. This cut results in a new strip that is twice the length of the original structure, but two-sided and two-edged. If this new strip is cut in half again, two separate strips are obtained this time. This experimental situation is a frequently used example for intuitively understanding the topological structure of the Möbius strip.
Scientific Importance of the Möbius Strip
The Möbius strip is not merely a theoretical structure. It has counterparts in modern science, particularly in chemistry, physics, and engineering.
Möbius Strip in Molecular Structures
The Möbius strip also appears at the molecular level. Since the 2000s, chemists have begun to create Möbius structures with carbon-based molecules. However, the stability of these structures has been a major problem. In a study published in 2021, a molecule with a complete Möbius strip structure was synthesized, and this discovery was regarded as the solution to a 50-year scientific problem. This synthesized molecule became the first example to carry the topological properties of the Möbius strip at a chemical level.1
Electronics and Nanotechnology Applications
The Möbius strip is among the structures used in modeling electron movement and magnetic fields. The symmetry conditions encountered by electrons moving in closed circuits can resemble the Möbius strip. Furthermore, the use of Möbius structures in nanotechnology is important for the future development of functional materials.
The Place of the Möbius Strip in Art
The Möbius strip is an inspiring structure not only in science but also in art. Artists have used the Möbius strip as a visual theme, particularly in sculpture and graphic design. The famous artist M.C. Escher frequently drew inspiration from this structure in his works. In this respect, the Möbius strip contributes to establishing a strong connection between mathematics and art.
