Magic squares are squares that contain particular numbers arranged in equal rows and columns such that the sum of each row and column (and sometimes diagonal) are the same. The earliest known magic square appeared in China dating back to at least 650 B.C.E.(Lo Shu and the tortoise who could talk with a boy after the flood), but magic squares were represented also in Persia, India, Arabia and Europe.

## The Moon Trajectory on a flat Earth

When considering earth as stationary and flat, the sun must be moving on a conic trajectory . (Maybe you can remember my article “Our Earth Pond and the Tent of the Sun”). In the same way the moon, in its movement in the space/ time, has to follow a trajectory moving in the shape of a cone. And this will be the basic theme of the following consideration.

The theory As indicated in the articleThe-paradox-of-gravity-not-respecting-the-energy-conservation-principle/ satellites are subject to a double different force, the gravitational one and the centrifugal one. This implies that the nearer a satellite is orbiting around the earth, the faster it has to move to win the bigger gravitational force and the other way round. To better describe this idea we have to introduce the concept of angular moment. This is the product of the impulse of the satellite[…]

Here you can find our book The reproducible reality Math is the key to understand and describe the universe. The question is: can we consider the opposite situation always true? I mean, is it possible to reproduce in the real world all the ideal abstractions that are possible in the math world?
