An interactive whiteboard is a large, interactive screen that connects a computer and a projector. The projector projects the computer's desktop onto the screen of the interactive whiteboard. The user can control the computer by using a special pen, finger or another tool to touch the screen of the interactive whiteboard. Normally, interactive whiteboards are fixed on walls. However, there are some mobile interactive whiteboards. Interactive whiteboards are used in many different places such as in classrooms, in work groups and in training rooms for professional coaching. Interactive whiteboards are the modern version of the traditional whiteboards used in schools.
The interactive whiteboard must be connected to an PC before you can use the whiteboard. Most whiteboards are connected to the computer's Serial port or to a USB port. Some newer systems can use a wireless connection to the computer.
The summary of use the interactive whiteboard includes three words: controlling, translation and presentation.

Sue (dinosaur)
"Sue" is the nickname given to FMNH PR 2081, one of the largest, most complete and best preserved "Tyrannosaurus rex" fossil ever found.
Sue was discovered in the summer of 1990 by Sue Hendrickson, a paleontologist, and was named after her. She contacted the Black Hills Institute, whose staff retrieved and prepared the bones.
First, ownership disputes were settled in court. There was a long dispute between the owners of the land, the Sioux tribe, the United States Department of the Interior, and the Black Hills Institute, whose staff had done the work.
The fossil was then auctioned in October 1997 for US$8.36 million, the highest amount ever paid for a dinosaur fossil.
After preparation, the skeleton became a permanent feature at the Field Museum of Natural History in Chicago, Illinois. The money had been raised by public subscription.
Some researchers think the skeleton shows evidence that Sue suffered from the painful condition known as gout.

Empoli
Empoli is a town in Tuscany, Italy, about 30 km southwest of Florence. It is 30 m above sea-level, to the south of the Arno. The plain of the town has been usable for agriculture since Roman times. Empoli is on the main railway line from Florence to Pisa and is well joined with the city of Siena.
Empoli has a long tradition as an agricultural centre. It has given its name to a local kind of artichoke.
Empoli was already settled in the time of the early Roman Empire, and still existed in the 4th century AD. The river near the city was a good route for the trade of agricultural products, together with the local amphorae.
Since the 8th century Empoli grew as a town around the castle, known as "Emporium" or "Empolis". In 1119 it was controlled by Guidi. In 1182 it went under Florentine rule. In 1260, after the Battle of Montaperti, Empoli was the seat of a famous council in which Farinata degli Uberti opposed the destruction of Florence. Later Empoli became an important fortress.

Larderello
Larderello is a "frazione" of the "comune" of Pomarance, in Tuscany in central Italy. Larderello is famous for its geothermal productivity.
The region was known from ancient times for its volcanic nature and for the very hot springs. The Romans used its sulphur springs for bathing. In 1827, François de Larderel, a Frenchman, invented a way of extracting boric acid from the volcanic mud by using steam to separate the two. The town Larderello has the name in honour of Larderel's work. The region was the site of a pioneering experiment in the production of energy from geothermal sources in 1904. Prince Piero Ginori Conti tested the first geothermal power generator on 4 July 1904, at the Larderello dry steam field in Italy. It was a small generator that lit four light bulbs. Later, in 1911, the world's first geothermal power plant was built there. In 1911, the world's first geothermal power plant was built in the Valle del Diavolo ("Devil's Valley"), named for the boiling water in the area. Larderello now produces 10% of the world's entire supply of geothermal electricity, amounting to 4,800 GWh per year.
