Níquel para tus pensamientos: urey y el origen de la luna
Resumen
Harold C. Urey fue
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- La ciencia lunar es la ciencia lunar.
- Historia del sistema solar Historia del sistema solar
Sus antecedentes:
- Discute las teorías de Harold C. Urey sobre el origen lunar.
- Compara las ideas de Urey con la hipótesis de la fisión de George Howard Darwin.
- Examina la defensa de Urey para las misiones lunares tripuladas basadas en la teoría de la captura.
Objetivo del estudio:
- Para analizar las hipótesis en evolución de Harold C. Urey con respecto a la formación de la Luna.
- Para conectar las teorías de Urey con los datos de observación de las misiones lunares.
- Para rastrear el razonamiento científico detrás del cambio de Urey en los modelos de selenogonía.
Principales métodos:
- Análisis histórico de las teorías científicas sobre el origen lunar.
- Revisión de la evidencia de los resultados de la misión Apolo, específicamente las abundancias elementales.
- Estudio comparativo de las hipótesis de captura y fisión para la formación de la Luna.
Principales resultados:
- Urey inicialmente favoreció la captura de la Luna por la Tierra, lo que influyó en su apoyo a los aterrizajes lunares.
- Los datos de la misión Apolo revelaron una deficiencia de elementos siderófilos en la corteza lunar.
- Esta deficiencia elemental contradecía la hipótesis de captura.
Conclusiones:
- Los datos del elemento siderófilo llevaron a Urey a abandonar la teoría de la captura.
- Urey tentativamente readoptó la hipótesis de la fisión como una explicación más plausible para el origen lunar.
- El estudio destaca cómo la evidencia empírica da forma a las teorías científicas a lo largo del tiempo.

Gravity between Spherical Bodies
Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

Circular Orbits and Critical Velocity for Satellites
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.

Kepler's First Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.
On the other hand,...

Kepler's Second Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
Gravitation
In the years before Newton, a general belief prevailed that different laws governed objects in the sky than objects on Earth. When Kepler wrote down the three laws of planetary motion, explaining in detail the geometrical properties of the planetary orbits around the Sun, there was no immediate idea to discern their connection with more fundamental laws. It was Isaac Newton who, in 1665–66, figured out the connection between planetary motion, the motion of the moon around the Earth, and the...
