Astronomical aberration is a phenomenon that makes a star, seen in a telescope, appear in a place slightly different from the expected. Aberration has been observed in 1727 by the English astronomer James Bradley who, in the course of his surveys, noticed that stars seemed to be subject to a slight movement within a period of one sidereal year. He thought that this movement depended on the position of the star inside the celestial sphere. Read more
Here the reader will find some of the measures of our earthly ponds and platform. The calculations given are the consequence of some premises I’m going to expose in this week blog article. Here I will consider Ezekiel’s book at chapter one and his vision of the four wheels with smaller wheels in their midst (1:16). Morover, I will give reasons for Cosmas Indicopleustis’ belief about the rectangular shape as the basic pattern of the earth. Read more
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. Read more
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.
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 ( I=mxv where I is the impulse, m is the mass of the satellite and v its speed) and the distance of the satellite from the Earth, R. Read more
