When the meteor falls, it leaves a line full of fantasy in the sky.

Points are the simplest shapes and the most basic components of geometric figures. As an object in 1 0 dimensional space. In other fields, point is also the object of discussion. A line is a figure composed of countless points. A line is a graph generated when a moving point moves. A line is a length without width.

The history of the point

Aristotle's theory of celestial bodies has mentioned in the third volume that points in mathematics have no size. He refutes Plato's view that mathematical geometry is a constituent element of physical entities (see regular polyhedron), and emphasizes that this is contrary to the mathematical definition at that time: the plane of mathematics has no thickness, so physical entities cannot be constructed.

He believes that if the mathematical plane has a thickness, then the mathematical line must have a width to form a plane, and the mathematical point must have a size to form a line. But mathematics has clearly defined that mathematical points have no size, so Plato's theory and mathematics are in conflict.
