Klein bottle

Klein Bottle - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

Operating instructions: Press the "Separate" or "Close" button to control the changes in the state of the Klein bottle model and understand the structural characteristics of the Klein bottle. Function Overview: Exhibition items consist of a set of detachable and closable Klein bottles, corresponding driving mechanisms, operating devices, LED effect lights, and exhibition stands. The audience presses the "split" or "close" button to control the changes in the state of the Klein bottle model and understand the structural characteristics of the Klein bottle. It is a closed surface without boundaries. And it can allow a moving object to pass through two surfaces on one orbit. Scientific principle: In mathematics, a Klein bottle refers to an undirected plane, such as a two-dimensional plane, which has no distinction between "inside" and "outside". In topology, the Klein Bottle is an undirected topological space. The Klein bottle was originally proposed by the German geometer Felix Klein. In 1882, the renowned mathematician Felix Klein discovered the famous "bottle" that was later named after him. The structure of a Klein bottle can be described as follows: there is a hole at the bottom of the bottle, and now the neck of the bottle is extended and twisted into the inside of the bottle, and then connected to the hole at the bottom. Unlike the cups we usually use to drink water from, this object has no "edges" and its surface does not end. It is different from a sphere, as a fly can fly directly from the inside of the bottle to the outside without crossing the surface (i.e. it has no distinction between inside and outside). Or it can be said that this bottle cannot hold water.
