In 654 AD, 900 years after the collapse of the Colossus, the Saracens plundered Rhodes and sold the metallic remains of the colossus. It is said that the buyer used 900 camels to transport the fragments to Syria . Thus the image of the god who once saved the city from the foreign invasion had a fate similar to that of the siege machines of Demetrius, which when sold financed the construction of the Colossus.
Lighthouse of Alexandria
The Lighthouse of Alexandria, or the Pharos, was a tall tower built between 285 and 247 BCE. It was built on the island of Pharos in Alexandria, Egypt to serve as a lighthouse for sailors. The top of the tower had a mirror that reflected sunlight during the day; a fire was lit at night.
The word for "lighthouse" in some languages is "pharos" or its equivalent
Legend holds that Ptolemy I Soter would not allow Sostratus to put his name on the tower, but the architect left the following inscription on the base's walls:
ΣΟΣΤΡΑΤΟΣ ΔΕΞΙΦΑΝΟΥ ΚΝΙΔΙΟΣ ΘΕΟΙΣ ΣΩΤΕΡΣΙΝ ΥΠΕΡ ΤΩΝ ΠΛΩΙΖΟΜΕΝΩΝ</small>. (Sostratus of Cnidus, son of Dexiphanes, to the Gods protecting those upon the sea.)
These words were hidden under a layer of plaster, on top of which was chiseled another inscription honoring Ptolemy the king as builder of the Pharos. After centuries the plaster wore away, revealing the name of Sostratus.
With a height estimated at between 115 and 145 meters (384 – 469 ft), it was among the tallest man-made structures on Earth for many centuries. It was identified as one of the Seven Wonders of the World by Antipater of Sidon. It was the third tallest building after the two Great Pyramids (of Khufu and Khafra). It was destroyed by earthquakes.
Divers discovered remains of the lighthouse in fall 1994 on the floor of Alexandria's Eastern Harbour. Some of these remains were brought up and were lying at the harbour on public view at the end of 1995. An episode of the PBS television series "Nova" chronicled the discovery. Later satellite imaging has revealed further remains. It is possible to go diving and see the ruins.
Telesto (moon)
Telesto is a tiny moon of Saturn. It was discovered by a number of astronomers in 1980, based from some observations from the Earth. It was named after Telesto in Greek mythology. Telesto orbits around Saturn together with much larger moon Tethys. Thus, Telesto is also known as a Trojan moon. The moon leads at a point 60 degrees in front of Tethys in its orbit. Another small moon, Calypso, orbits with Telesto.
Calypso (moon)
Calypso is a small moon of Saturn. It was discovered by a few astronomers in 1980, based on observations from the Earth. It is named after Calypso in Greek mythology. Calypso is a Trojan moon, as it orbits together with larger moon Tethys. It orbits behind Tethys by 60 degrees in its orbit around Saturn. Telesto is another moon which shares Calypso's orbit. Calypso was named after Calypso, a nymph in Greek mythology.
Pallene (moon)
Pallene is a small moon of Saturn. It was discovered by the Cassini Imaging Science Team in 2004. It orbits between two larger moons, Mimas and Enceladus. Pallene is about 4 km in diameter.
Methone (moon)
Methone is a small moon of Saturn. It was discovered by the Cassini Imaging Science Team in 2004, the same time as a close-by moon, Pallene. It is only about 3 km in diameter.
Dione (moon)
Dione is the fourth largest moon of Saturn. It has a diameter of 1,123 km (698 miles). It was discovered in 1684 by Giovanni Domenico Cassini. It is named after the titan Dione in Greek mythology. The moon has many craters and ice cliffs. It is tidally locked with Saturn, meaning the same face of Dione always faces Saturn.
Helene (moon)
Helene is a moon of Saturn. It shares its orbit with larger moon Dione. It leads in front of Dione in its orbit around Saturn by 60 degrees. It was discovered in 1980 by a couple of astronomers based on observations from the Earth.
Polydeuces (moon)
Polydeuces is a small moon of Saturn. Its diameter is only 3.5 km. It shares its orbit with larger moon Dione. It was discovered by the Cassini Imaging Science Team in 2004.
Boyfriend
A boyfriend is a term which usually means the male partner in a romantic non-marital relationship. Partners in a non-marital relationship are sometimes called "significant others". Using the word "boyfriend" to mean "a male partner or lover" was first done in 1906. It became popular in the 1920s, when people started to go out on dates rather than have romantic meetings at home.
It is less common to use the term "boyfriend" to mean a male friend in a platonic relationship.
Aspirator
An aspirator is a device that makes vacuum, because of the Venturi effect. In the aspirator, fluid flows through it. The tube gets more thin, making the fluid flow faster, and making the pressure smaller. Then, vacuum is taken from it. The aspirator is also known as an ejector or a filter pump.
The most common type of aspirator is the water aspirator. It is used in laboratories for chemistry and biology. The aspirator has a fitted tee, which is attached to a faucet. It has a hose barb on one side. The flow of water passes through the straight part of the tee, which restricts the water flow at the intersection with the hose barb. The vacuum hose should be connected to this barb.
The strength of the produced vacuum is limited by the vapour pressure of the flowing water. However, the strength of the vacuum is not limited if a gas is used as the working force.
Venturi effect
The Venturi effect is a case where fluid flows through a tube that is narrow. The velocity of the fluid increases as it flows through the narrower tube while the pressure decreases, due to conservation of energy. The effect is an example of Bernoulli's principle.
With the B.E. a simple flow of either A. Fluids, or B. Air, will cause pressure. Within an amount of time, this will cause a decrease in pressure and have the potential of creating energy.
Santa Fe, Argentina
Santa Fe is the capital city of the province of Santa Fe in Argentina. As of 2001, about 369,000 people lived there.
Geography of Argentina
Argentina is almost 3,700 km long from north to south, and 1,400 km from east to west (maximum values). It can be divided into three parts: the Pampas in the central part of the country, Patagonia in the southern part down to Tierra del Fuego; and the Andes mountain range along the western border with Chile, with the highest point located in the province of Mendoza. Cerro Aconcagua, at 6,960 metres (22,834 ft), is the Americas' highest mountain.
The most important rivers include the River Plate, Paraguay, Bermejo, Colorado, Uruguay and the largest river, the Paraná.
List of retired Atlantic hurricane names
This article is about a list of retired Atlantic hurricane names. Atlantic hurricane names only get retired if and when they are notable enough by causing a lot of damage or killing many people. They can also be retired if and when the government or country requests the name to be retired, by the World Meteorological Organization.
