When lightning strikes, the surface rubs electrons from the lightning, and a spark of electricity shoots from the lightning to the surface. In a thunderstorm, the lower cloud has as many as 100 million volts of electricity. This electricity is given out either within the cloud, to the ground, to another cloud, or into the air. Lightning has been known to travel from the ground upwards to the cloud. In 1993, scientists discovered lightning bolts that shot upward from the top of a cumulonimbus cloud.
People can make and study lightning with a Tesla coil or a Van de Graaff Generator.
Benjamin Franklin experimented with electricity and was interested in lightning. He discovered many things about lightning. In 1772, he was the first to show that a thunderstorm lets out electricity. In his book he suggested an experiment to test it. Joseph Priestley said that Franklin flew a kite to prove the presence of electricity in the storm, using a dry silk string to protect himself from the electricity in the wet hemp kitestring.
Roseau
Roseau is the capital city of the Caribbean island of Dominica. It is home to more than fourteen thousand people.
Roseau (Dominican Creole: Wozo) is the capital and largest city of Dominica, with a population of 14,725 as of 2011.[1] It is a small and compact urban settlement, in the Saint George parish and surrounded by the Caribbean Sea, the Roseau River and Morne Bruce. Built on the site of the ancient Island Carib village of Sairi, it is the oldest and most important urban settlement on the island of Dominica.
It is on the west (leeward) coast of Dominica and has a combination of modern and colonial French architecture.
Roseau is Dominica's most important port for foreign trade. Some exports include bananas, bay oil, vegetables, grapefruit, oranges, and cocoa. The service sector is also a large part of the local economy. There are several private institutions registered in Dominica, like Ross University, Ballsbridge University, international university for graduate studies, All Saints University, New World University, Western Orthodox University.
There is a prominent diocese called Roman Catholic Diocese of Roseau.Event
An event is something which happens or takes place. An event is brief, possibly extremely brief. Contrast with a process, which takes time.
Paint
Paint is the general term for liquid that is used to add colour to the surface of an object by covering it with a pigmented (coloured) coating. As a verb, painting means "applying paint" (putting paint onto something). Someone who paints is called a painter.
Paint is made from a coloured pigment which is usually a powder. The powder is made from different chemicals. Some of the pigments come straight from natural things like clay. The pigment must be made wet by mixing it with something that will make it stick onto the surface and not come off easily. The wet stuff is called the "medium" or "vehicle". Some paints are just mixed with water. Other paints are mixed with oils or chemicals of different sorts. Most painters buy paint that is already mixed. House-painters use paint already mixed in large cans. Artists buy paint in tubes. Some artists buy dry pigment and mix it for themselves.
The paint is usually put onto the surface with a paint brush. Paint brushes are used by painters of all sorts. House painters also use rollers and spray-guns to put on paint. A modern invention is paint in a pressurized can which can be sprayed on. Some modern artists also use spray paint. In factories there are machines which spray paint onto objects. Cars are usually painted in this way.
Paint must be allowed to dry. Some paints such as watercolour, dries in a few minutes. Other paints, such as artist's oil paint, can take days or even weeks to dry. Most other types of paints fit between these two. Many types of paint are best if they are put on in several layers. The painter must first prepare the surface so it is smooth, clean and dry. The first layer of paint is often an "undercoat" or "ground" which is smooth and sticks very well. The coloured paints are put on over the top. A house-painter who is using oil paint on a wooden window frame might used three layers of paint to give very good protection from the weather. Other types of modern house paint only need one layer, particularly on the inside. Artists using oil paint and tempera often use many layers to get just the right effect.
Paint has four important uses.
Paint is used to protect all sorts of buildings and structures from the effects of water and sun. Wooden buildings such as houses are usually painted because a coat of paint prevents water seeping into the wood and making it rot. The paint also helps to prevent the wood from drying out in the hot sun.
Metal structures and objects of all sorts are painted to stop them from rusting. A very large steel structure such as a bridge must have a team of painters who keep the paint in good condition all the time.
Paint is used to decorate all sorts of objects. Since pre-historic times, people have painted the inside walls of their houses to make them look attractive. Painting and decorating the exterior (outside) and interior (inside) of houses is an important industry in many countries. There are many types and colours of paint to chose from.
All sorts of other objects are painted to make them attractive. This includes furniture, toys, tools and utensils, and street fittings. Sometimes things made of wood such as furniture are painted in decorative patterns. In some countries, many people enjoy decorating furniture and other small things like trays and boxes. This is one form of what is often called Folk Art. In other countries such as Japan, painting furniture is a very skilled profession and an antique piece of decorated furniture is very valuable.
Other people enjoy the hobby of painting small objects such as model planes or soldiers.
Paintings are pictures that are done in paint. Many different types of paint are used for paintings. They include tempera, oil paint, gouache, watercolours and acrylic paints. The paintings are usually done on board, canvas or paper. Many other famous paintings are done on the walls and ceilings of buildings, such as the Sistine Chapel ceiling which was painted by Michelangelo.
Many artists are famous for their painted pictures. Old, beautiful and famous paintings are very valuable and are sometimes sold for millions of dollars. Famous painters include Giotto, Leonardo da Vinci, Titian and Rembrandt.
Paint is a very good way to give important information to people, using painted signs. Painted signs include lane markings on the road, street signs of all sorts, advertising signs and warning signs.
Mark Antony
Mark Antony (Latin: Marcus Antonius, 14 January "circa" 82 BC – 1 August 30 BC), was a Roman patrician from an upper-class family. He became a general and politician. He was an important supporter of Julius Caesar as a military commander and administrator.
After Caesar's assassination, Antony, left as sole Consul, surrounded himself with a bodyguard of Caesar's veterans. He forced the senate to transfer to him the province of Cisalpine Gaul, at the time administered by Brutus, one of the conspirators. Brutus refused to surrender the province and Antony set out to attack him in the beginning of 43 BC, besieging him at Mutina.
Encouraged by Cicero, the Senate denounced Antony. In January 43 they granted Octavian "imperium" (commanding power), and sent him to relieve the siege. In April 43, Antony's forces were defeated at the battles of Forum Gallorum and Mutina, forcing Antony to retreat to Transalpine Gaul.
