When e2 becomes e4, e1 becomes e1e2 and not e1 because the new position of e2 is now occupied by the piece that was previously on e1. Therefore, to indicate the movement of the piece from e1 to e2, the notation e1e2 is used. This helps to clearly show the movement of the piece from its original position to its new position on the chessboard. **

An elliptical orbit is a type of orbit in which an object, such as a planet or satellite, follows an oval-shaped path around another object, typically a star or planet. In an elliptical orbit, the object's distance from the central body varies, with the closest point being the perigee and the farthest point being the apogee. The shape of the ellipse is determined by the gravitational pull of the central body and the object's velocity. Elliptical orbits are common in our solar system, with planets like Earth and Mars following elliptical paths around the Sun. **

Elliptical orbits occur due to the gravitational forces between celestial bodies. When an object is under the influence of a central force, such as gravity, its path will often take the shape of an ellipse. This is because the force of gravity is stronger at shorter distances, causing the object to move faster when closer to the center of mass and slower when farther away. As a result, the object follows a curved path that is elliptical in shape. **
