Waistline (clothing)
The waistline is the part of a piece of clothing that sits on the wearer's waist. The actual position of the waitline can be different depending on the fashion or how the person chooses to wear the garment, but it is normally just above the hips.
Waistlines can be secured with a variety of methods, such as buttons, knots and zippers. A waistband is a strip of elastic rubber that adjusts to keep the item tight against the body.
Waistline
Waistline can mean several things:
Heliocentrism
Heliocentrism is the idea that the Earth and other planets revolve around the Sun, which is the center of the solar system. Many people proposed heliocentrism, such as Aristarchus of Samos from ancient Greece, but Nicolaus Copernicus was the first to think of good reasons why it is true. This was the beginning of modern astronomy.
Before Copernicus, most people thought that the Sun and the other planets revolved around the Earth (this was called geocentrism). This is because if you stand on Earth, it looks like the Sun and stars are moving across the sky. However, when people watched for many years they saw many things that did not make sense if the Earth was the center of the Solar system. For example, sometimes the planets seemed to move back and forth instead of moving around the Earth. Copernicus explained why these things happen in 1543, when he published the book "De revolutionibus orbium coelestium" ("On the revolutions of the heavenly spheres"). This gave his reasons for thinking the Sun was at the center instead.
Other astronomers who made further advances after Copernicus were Johannes Kepler and Galileo Galilei. For example, Kepler showed that the planets do not orbit in perfect circles, and Galileo built very good telescopes that helped to confirm the heliocentric model.
Copernicus also thought that the sun was the center of the universe, but we now know that this is incorrect. The Sun is part of the Milky Way galaxy which is one out of billions of galaxies.
Trance
Trance describes a state of mind. A trance is when a person is conscious, and not sleeping, but is unaware of what is happening around him or her.
The term "trance" is associated with hypnosis, meditation, magic, flow, religion, and certain kinds of music. It is an "altered state of consciousness".
There are many efforts to define what a trance is. Some think it is a borderland between normal consciousness and spirituality
The most straightforward example is when a person is hypnotized, they are in a trance. Conscious, and responding to the hypnotist, the person seems to block out other thoughts and other information.
Another common example is the day-dream, where a person's mind drifts across private thoughts. Everyone daydreams, but young children constantly daydream, and have vivid imaginary fantasies. This is entirely normal. In the language of psychology, this kind of temporary separation from one's surroundings is called "dissociation". Research shows that a lot is going on when we daydream.
There are many examples of trance in religion. African animistic religions, such as that of the Yoruba, feature dances in celebration of the spirits. Under the influence of rhythm and song, a group dances, often for hours at a time. During this time, various members of the group may fall into trances, and some may act as if possessed by one of the spirits being worshiped. States of "spiritual ecstasy" are known in most forms of Christian worship. It is a main part of those aspects of religion known as "mysticism".
Spitzer Space Telescope
The Spitzer Space Telescope is a telescope launched into space by NASA in 2003. It is the fourth telescope in the Great Observatories program (the Hubble Space Telescope was the first). The Hubble Space Telescope takes pictures of visible light, and the Spitzer Space Telescope takes pictures of infrared light. Unlike Hubble, Spitzer orbits the Sun instead of the Earth.
The Spitzer Space Telescope is named after the scientist Lyman Spitzer. It was planned to last for 2.5 years, but it actually lasted until 2009 when it exhausted its supply of coolant. Some parts of the telescope can work even when they are warm, and are still working.
The Spitzer Space Telescope was able to see very good detail. Spitzer was the first telescope that could see light from extrasolar planets (planets outside the Solar System.) It was also able to see some of the first stars in the universe, believed to be only 100 million years after the Big Bang.
Age of the universe
In cosmology, the age of the universe is the amount of time since the Big Bang. The best measurement of the age of the Universe is 13.8 billion years (specifically, 13.798±0.037 billion years). The most recent and most accurate measurements were made by the Planck spacecraft. These measurements were made using the cosmic microwave background radiation and the expansion of the Universe.
In the 1800s, evidence from geology showed that the Earth was at least millions of years old. Later, it was thought that the universe was unchanging. However, in the 1920s, Georges Lemaître and Edwin Hubble determined that the universe was expanding (see Hubble's law). Although the estimates made using the initial data were low, radioactive dating on Earth could be used to give measurements of 11–20 billion years to 13–15 billion years. Eventually, scientists were able to make much better measurements using spacecraft.
Nominative case
In grammar, the nominative case is the grammatical case used when talking about the subject of the sentence. For example, "the boy kissed the girl."
The boy is the subject, so the nominative case is used.
Genitive case
In grammar, the genitive case is the grammatical case used when talking about possession: something that belongs to someone. For example, in the sentence "the boy's bike was red," the bike belongs to the boy. The word "boy's" is in the genitive case.
NuSTAR
NuSTAR is a telescope launched into space by NASA in 2012. It is the eleventh satellite in the "Small Explorer" program. Telescopes in space can see much better than on Earth, because the telescopes on Earth need to look through the atmosphere.
NuSTAR measures high-energy X-rays, which have a much higher frequency than visible light. It uses special optical devices to do this, so it works differently from a normal telescope. This type of telescope is called a Wolter telescope.
NuSTAR is searching for black holes. It is also looking at supernovae to help understand how the chemical elements are created. One of the first discoveries made by NuSTAR, along with another space telescope called XMM-Newton, was to measure the spin rate of a supermassive black hole for the first time.
Malahide
Malahide is a town near Dublin, Ireland. It is on the coast, right beside the estuary. It is in the administrative county of Fingal, and the traditional County Dublin, Ireland.
Carmelo Flores Laura
Carmelo Flores Laura (likely born July 16, 1906 – June 9, 2014) was a centenarian from Bolivia, who some believed to be born in 1890. That would have made him the person living to be the oldest ever known. However, other documents was found, that indicated he was actually born in 1906. Flores himself only said that he was about 100 years or more, which in that case was correct.
Laura was born on July 16, 1906 in Bolivia.
Carmelo Flores Laura worked for the rancher who owned Frasquia, a rural area of Bolivia near Lake Titicaca, until 1952. At that time, the government seized the land and redistributed it to peasants such as Flores. He has lived there since, never traveling father than La Paz, from his home.
Flores had three children, one of which is alive as of 2013 (Cecilio, aged 67). He has 40 grandchildren and 19 great-grandchildren. His wife died in the 2000s.
The Bolivian government was said to be planning to officially honor Flores as "a living heritage" of the Bolivian people.
