In September 2011, it was reported that a tau neutrino had traveled faster than the speed of light in a major release by CERN; however, later updates from CERN on the OPERA project indicate that the faster-than-light readings were resultant from "a faulty element of the experiment's fibre optic timing system".
In modern physics the term "tachyon" often refers to imaginary mass fields rather than to faster-than-light particles. Such fields have come to play an important role in modern physics.

Gelatin
Gelatin is a protein substance that comes from collagen. Collagen is a natural protein found in the tendons, ligaments, and tissues of mammals as well as fish. Gelatin has no smell, no taste, and is either colorless or light yellow. It can be found in sheets, flakes, or as a powder. It can be dissolved in water, but not in alcohol.
It is made by boiling the connective tissues, bones and skins of animals, usually cows and pigs. Once the boiling is done, the collagen will cool and make a jelly. As a food, gelatin is used to make jellied desserts; used in the preservation of fruit and meat, and to make powdered milk. Gelatin can also be used as glue for matches or for paper money. You can also find it used as the syrup in medicine, also known as medicine emulsions. Gelatin is also found in some makeup.
Gelatin is classed as a liquid when above room temperature but reverts to a solid if below room temperature.
Because gelatin comes from animals, vegetarians and vegans do not eat or use products that have gelatin added. Some religious or cultural groups also do not eat gelatin because of the animals used to make it. For example, people that keep kosher or halal will not eat gelatin because it is often made from cows. Alternatives to gelatin are products like agar or carrageenan which comes from seaweed or pectin which comes from plants.
Christian naturism
Naturist Christians are the Christians who practice naturism or nudism, and are a part of the clothes-free movement. They believe that the human body was the greatest making of God. It is not shameful and should not be covered. Naturist Christians can be found in almost all of the different groups of Christianity, called "denominations". They do not find any conflict with the teachings of the Bible, and living their lives and worshiping God without any clothing. However, most have various differences with New Age and man-centered philosophy (called "humanism") which is common among other naturists and wish to be separated from it. This includes not worshiping nature at all.
In the Book of Genesis, Adam and Eve were living in the Garden of Eden as 'man and wife' . They ate the fruit not allowed by God, after being talked into it by the devil in the form of a snake. Then their eyes were opened, and they knew that they were naked. So, they gathered fig leaves to be used as simple clothing to cover their sexual organs. These became lacking very quickly, and Adam and Eve hid themselves from God in the trees.
Lake Eyre
Lake Eyre (pronounced "air") is the lowest point in Australia, at about below sea level. When it fills with water, it is the largest lake in Australia, being long and wide. It is also in the driest part of Australia, getting only about of rain each year. It is in the north of South Australia, about north of Adelaide. The lake was named after the explorer, Edward Eyre, who was the first Europen to see it in 1840. It is the centre of the Lake Eyre National Park.
Lake Eyre is in the driest desert region of central Australia. It is a large endorheic lake system, which means that the water flows in, but does not flow out. As the water evaporates, the lake dries up leaving a dry salt lake. The lake does not usually completely dry up, there is often water in small areas on the lake surface. The rate that the water dries up is per year, that is about 20 times more than the rainfall in the area.
During the wet season the rivers from Queensland flow towards the lake through the Channel Country. These rivers drain about one sixth of Australia, an area the size of Spain. How much water reaches the lake depends on how rain falls in Queensland. Since 1885 the lake has filled in 1886/1887, 1889/1890, 1916/1917, 1950, 1955 and 1974-1976. In 1974 Lake Eyre was deep. Local rain filled Lake Eyre to in 1984 and 1989. Very heavy rain in January 2007 took about six weeks to reach the lake but put only a small amount of water into it. In February 2009, water from flooding rains in Queensland were flowing along the creeks to the lake covering about 40 km per day. The lake fills to about every three years, to , every ten years, and fills up about four times every 100 years.
When Lake Eyre is full, the water is almost fresh and native fresh water fish can live in it. The lake becomes saltier as the salt crust dissolves over six months. This kills millions of fish. When about 4m deep the Lake is as salty as the sea. It becomes more salty as the water evaporates. At about 500mm depth the Lake becomes a "pink" color because of a beta-carotene pigment made by the algae "Dunaliella salina".
Beaches made by wave action suggest that during the Medieval Warm Period Lake Eyre possibly held "permanent water" at levels above those of 1974.
The local Aboriginal people, the Arabunna people, have stories that explain the creation of Lake Eyre. These stories are part of their sacred traditions, and are only told to initiated people.
Fresh water fish found in the full lake include boney bream ("Nematolosa erebi"), the Lake Eyre Basin sub-species of golden perch ("Macquaria ambigua") and various small hardyhead species ("Craterocephalus spp"). The Lake Eyre hardyhead, can live in water up to 15 times saltier than the ocean.
When there is water more than 8 million birds, from more than 60 different species, flock to the lake. The pelicans are usually the first to arrive, followed by silver gulls, hoary headed grebes, Australasian grebes, cormorants, ducks, banded stilts, kites, falcons and wedge tailed eagles. Scientists still do not know how the birds know when the lake holds water.
There is also a lizard, the Lake Eyre Dragon, Ctenophorus maculosus, that lives in the cool mud below the salt crust of the lake.
The "Lake Eyre Yacht Club" is a small group of people who sail on the lake's floods, including recent trips in 1997, 2000, 2001, 2004, 2007 and 2009. A number of 6 m Trailer Sailers sailed on Lake Eyre in 1975, 1976 and 1984 when the flood depth reached 3–6 m.
The salt crust on the lake is not thick and can break like glass under a person's weight. At Level Post Bay, the crust is more than one metre thick, and because of its flat surface it has been the site for various land speed record attempts. In 1964, British driver, Sir Donald Campbell, set a new record of , in the "Bluebird-Proteus CN7".
Castanets
Castanets are percussion instruments which come from Spain. They are often used in an orchestra. Castanets are hollowed-out wooden shells. A hardwood such as ebony or rosewood is used.
Castanets are used in pairs. Traditionally two pairs are played together, one pair held in each hand. There is a string which passes through small holes in the shells. The player winds the string around the thumb and finger so that the two shells can be clicked together. The two pairs of castanets used are slightly different sizes so that they make a slightly different pitch. The higher pair, known as "hembra" (female), is usually held in the right hand, with the larger "macho" (male) pair held in the left.
Castanets are traditionally played by singers and dancers. Spanish folk dancers often use castanets. They are often associated with flamenco dancing.
