Precession is the wobble of the Earth's axis. This gyroscopic motion is due to the tidal forces exerted by the sun and the moon on the solid Earth, which has the shape of an oblate spheroid rather than a sphere. The sun and moon contribute roughly equally to this effect. Its period is about 26,000 years.
When the axis points toward the Sun, one polar hemisphere has a greater difference between the seasons while the other has milder seasons. The hemisphere that is in summer at perihelion receives much of the corresponding increase in solar radiation, but that same hemisphere in winter at aphelion has a colder winter. The other hemisphere will have a relatively warmer winter and cooler summer.
Planets orbiting the Sun follow elliptical (oval) orbits that rotate gradually over time (apsidal precession).
In addition, the orbital ellipse itself precesses in space, primarily as a result of interactions with Jupiter and Saturn. This shortens the period of the precession of the equinoxes from 25,771.5 to ~21,636 years.
The inclination of Earth's orbit drifts up and down relative to its present orbit with a cycle having a period of about 70,000 years. Milankovitch did not study this three-dimensional movement. This movement is known as 'precession of the ecliptic' or 'planetary precession'.
Researchers noted this drift, and also that the orbit moves relative to the orbits of the other planets. The invariable plane, the plane that represents the angular momentum of the Solar System, is approximately the orbital plane of Jupiter. The inclination of the Earth's orbit has a 100,000 year cycle relative to the invariable plane. This is very similar to the 100,000 year eccentricity period. This 100,000-year cycle closely matches the 100,000-year pattern of ice ages.
It has been proposed that a disk of dust and other debris exists in the plane, which affects the Earth's climate. The Earth moves through this plane around January 9 and July 9, when there is an increase in radar-detected meteors and meteor-related noctilucent clouds.
A study of the Antarctic ice core, using oxygen-nitrogen ratios in air bubbles trapped in the ice, concluded that the climatic response documented in the ice cores was driven by Northern hemisphere insolation as proposed by the Milankovitch hypothesis. This is an additional validation of the Milankovitch hypothesis by a relatively new method. It is not consistent with the "inclination" theory of the 100,000-year cycle.

Estopa
Estopa are a popular duo from Cornellà, Spain. The band consists of the brothers José and David Muñoz, who sing different sounds reflecting many genres, including rock, rumba and flamenco. Their first album, "Estopa", has sold over 1,000,000 copies to date. Their latest album, "Voces de Ultrarumba", sold more than 200,000 copies on its first day of release. Their music has made them one of the most successful rock groups in Spanish history.
José Muñoz, the younger brother, was born in 1978. He plays guitar for Estopa. David Muñoz, the older brother, was born in 1976. He is the singer and also plays some guitar. They are brothers born in Extremadura. The brothers grew up listening to such bands as Los Chichos, Los Chunguitos, and Bordón on their trips with their parents from Cornellà to Zarza Capilla, where their parents were from.
As they grew up, José and David attended college for some time before deciding that it was not right for them. After quitting their studies, they worked for a factory manufacturing car parts for the company SEAT. It was in that factory where they began composing their earliest songs and they began to play in local bars.
After playing a song for the bosses at BMG Music España, Estopa was given a record deal.

Jeffrey Skilling
Jeffrey Keith "Jeff" Skilling (born November 25, 1953 in Pittsburgh, Pennsylvania) is an American former businessman and former president of Enron Corporation. He is best known for being involved in the Enron scandal. Skilling was ultimately convicted of multiple federal felony charges that related to Enron's financial collapse, and he is currently serving a 24-year, four-month prison sentence at the Federal Correctional Institution in Englewood, Colorado. The Supreme Court of the United States heard arguments in the appeal of the case on March 1, 2010. On June 24, 2010, the Supreme Court vacated part of Skilling's conviction and sent the case back to the lower court for further proceedings.
In 2013, the United States Department of Justice said that they had reached a deal with Skilling that resulted in 10 years being cut from his sentence. He can be released sometime in 2019.
Charles J. Guiteau
Charles Julius Guiteau (September 8, 1841 – June 30, 1882) was the man who assassinated the 20th President of the United States, James A. Garfield.
