Sphere curvature calculator

Sphere curvature calculator Scheme Ángulos: α: angle variation $\overline{\rm A_0 B_0}$. α1: angle variation$\overline{\rm A_0 G_0}$. α2: angle variation $\overline{\rm G_0 B_0}$. Distancias: d: distance from $\overline{\rm A_1 B_1}$. d1: distance from $\overline{\rm A_1 G_0}$. d2: distance from $\overline{\rm G_0 B_1}$. h0$: observer height, $\overline{\rm A_0 A_1}$. h1: target hidden height, $\overline{\rm B_0 B_1}$. R: radius of the sphere / circle. Puntos: A0: base of the observer A1: top of the observer B0: base of hidden object B1: top of hidden object G0: curvature shear, geometric limit C: center of the circle / sphere Representation of a sphere of radius (R=6371 Km) with distances and heights. ...

The problem of common ancestors of a generation

A few months ago when I was doing my family tree I had a doubt about the common ancestors. One of the branches of the family data records went back to the seventeenth century (around 1650), specifically the eleventh generation. Based on this I asked myself the following question: how many common relatives of the eleventh generation did I have? To get the result I thought if the first generation we have 2 parents, the second 4 grandparents, the third 8 great-grandparents, the fourth 16 great-great-grandparents and so on. The number of members of each generation is double the previous one, it follows a serial pattern expressed with the equation: $Y = 2^n$, where Y: is the number of members of each generation n: is the number of the generation, $n \in N$. ...

What is the horizon?

Introduction. To answer this question let’s start by analyzing its etymology, the word “horizon” comes from the Ancient Greek ὁρίζων (horízōn, “definite boundary”) participle of the verb [ὁρίζω](https://en. wiktionary.org/wiki/%E1%BD%81%CF%81%CE%AF%CE%CE%B6%CF%89#Ancient_Greek “ὁρίζω”) (horízō, “to define, determine”) which comes from the noun ὅρος (hóros, “boundary”). To observe the horizon a three-dimensional space is necessary, in higher physical dimensions it could also occur but with another geometry. It also requires a separation of media to observe it, in which the horizon forms the base that separates both media while the vertical would be the height, in the case of the earth the horizon separates the atmosphere from the land or sea surface. ...

Earth models comparison

Sphere vs. plane In this article we will present in an organized way all types of arguments between the models proposed to describe the shape of the Earth, the spherical model and the flat circular model, in order to compare and try to find the model that best fits reality. From now on it will be cited as spherical or flat as appropriate. Brief description (shape, rotation, sky) Spherical: official version from the 15th to the 15th century. XV to s. XXI, planet inclined 23.4º with respect to the plane of the ecliptic. The Earth has its own rotational motion around the Sun as it moves in the Solar System (Heliocentric model), with the Moon in asynchronous motion rotating around it. Flat: Flat round motionless round Earth. The Sun and Moon rotate at the top around the Earth (Geocentric model), forming the days and nights. Celestial Vault Verifiable from Earth Magnetic field ...

Heliocentrism deception

Official version In 2021 for the official science the Earth is a sphere that rotates and moves along with the Moon (only satellite) and with more planets all orbiting around the Sun forming the solar system. In addition this system rotates around a larger system within the Milky Way galaxy, which is located within a supercluster of galaxies, within an observable universe in constant accelerated expansion. This system is formed by the planets listed by their proximity to the Sun as: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. ...
