Lost Cities

September 28th 2007 12:34
In the popular imagination lost cities were real, prosperous, well-populated areas of human habitation that fell into terminal decline and whose location was later lost. Most lost cities are found, and have been studied extensively by scientists. Abandoned urban sites of relatively recent origin are generally referred to as ruins.

Lost cities generally fall into three broad categories: those whose disappearance has been so complete that no knowledge of the city existed until the time of its rediscovery and study, those whose location has been lost but whose memory has been retained in the context of myths and legends, and those whose existence and location have always been known, but which are no longer inhabited. The search for such lost cities by European adventurers in the Americas, Africa and in Southeast Asia from the 15th century onwards eventually led to the development of the science of archaeology.


Below are some pictures of various Lost Cities around the world today. More photos can be seen here.

Space Walking

September 26th 2007 12:25
Space Walking or Extra-vehicular activity (EVA) looks like the most calming and awe-inspiring activity you could do.

Space Walk EVA Spacewalk


However, an untethered Space Walk like the one you see above is very dangerous for a number of reasons. The primary one is collision with space debris. Orbital velocity at 300 km above the Earth (typical for a Space Shuttle mission) is 7.7 km/s. This is 10 times the speed of a bullet, so the kinetic energy of a small particle with a mass 1/100th that of a bullet (e.g. a fleck of paint or a grain of sand) is equal to that of a bullet. Every space mission creates more orbiting debris, so this problem will continue to worsen (see also Kessler Syndrome).

Another reason for danger is that external environments in space are harder to simulate before the mission, though approximate simulations can be achieved at facilities like NASA's Neutral Buoyancy Laboratory. Space walks are avoided for routine tasks because of their danger. As a result the EVAs are often planned late in the project development when problems are discovered, or sometimes even during an operational mission. The exceptional danger involved in EVAs inevitably leads to emotional pressures on astronauts.

Other possible problems include a space walker becoming separated from their craft or suffering a spacesuit puncture which would depressurize the suit, causing anoxia and rapid death if the space walker is not brought into a pressurized spacecraft quickly

Would you still like to give it a try?

Dragon Art

September 24th 2007 11:59
The dragon is a mythical creature typically depicted as a gigantic and powerful serpent or other reptile with magical or spiritual qualities.

Most experts on mythology and folklore argue that legends of dragons are based upon ordinary snakes and similar creatures coupled with common psychological fears amongst disparate groups of humans.

Some believe that the dragon may have had a real-life counterpart from which the various legends arose — typically dinosaurs or other archosaurs are mentioned as a possibility — but there is no physical evidence to support this claim, only alleged sightings collected by cryptozoologists. In a common variation of this hypothesis, giant lizards such as Megalania are substituted for the living dinosaurs. Some believe dragons are mental manifestations representing an assembly of inherent human fears of reptiles, teeth, claws, size and fire in combination.

Dinosaur and mammalian fossils were occasionally mistaken as the bones of dragons and other mythological creatures — for example, a discovery in 300 BC in Wucheng, Sichuan, China, was labelled as such by Chang Qu. It is unlikely, however, that these finds alone prompted the legends of such monsters, but they may have served to reinforce them.

As with every mythological creature, dragons are perceived in different ways by different cultures. Below is some beautiful and varied Dragon Art, more can be seen here.

Zebras and Their Stripes

September 19th 2007 13:02
The Zebra is a member of the horse family, native to eastern and southern Africa. They are best known for their distinctive black and white stripes.

Zebras are white with black stripes and their bellies have a large white blotch for camouflage purposes. The reasons is it believed that that zebras are black with white stripes are: (1) white equids would not survive well in the African plains or forests; (2) The quagga, an extinct zebra species, had the zebra striping pattern in the front of the animal, but had a dark rump; (3) when the region between the pigmented bands becomes too wide, secondary stripes emerge, as if suppression was weakening. The fact that zebras have white bellies is not very strong evidence for a white background, since many animals of different colours have white or light coloured bellies.

The stripes are typically vertical on the head, neck, forequarters, and main body, with horizontal stripes at the rear and on the legs of the animal. The "zebra crossing" is named after the zebra's white and black stripes.

Zoologists believe that the stripes act as a camouflage mechanism. This is accomplished in several ways. First, the vertical striping helps the zebra hide in grass. While seeming absurd at first glance considering that grass is neither white nor black, it is supposed to be effective against the zebra's main predator, the lion, which is colour blind. Theoretically a zebra standing still in tall grass may not be noticed at all by a lion. Additionally, since zebras are herd animals, the stripes may help to confuse predators - a number of zebras standing or moving close together may appear as one large animal, making it more difficult for the lion to pick out any single zebra to attack. A herd of zebras scattering to avoid a predator will also represent to that predator a confused mass of vertical stripes travelling in multiple directions making it difficult for the predator to track an individual visually as it separates from its herdmates, although biologists have never observed lions appearing confused by zebra stripes.

Zebras and their stripes for camouflage


A more recent theory, supported by experiment, posits that the disruptive colouration is also an effective means of confusing the visual system of the blood-sucking tsetse fly. Alternative theories include that the stripes coincide with fat patterning beneath the skin, serving as a thermoregulatory mechanism for the zebra, and that wounds sustained disrupt the striping pattern to clearly indicate the fitness of the animal to potential mates.

White Rhinoceros

September 17th 2007 12:42
The White Rhinoceros or Square-lipped rhinoceros is one of the five species of rhinoceros that still exist and is one of the few megafauna species left. Behind the elephant, it is probably the most massive remaining land animal in the world, along with the Indian Rhinoceros which is of comparable size. It is well known for its wide mouth used for grazing and for being the most social of all rhino species. The White Rhino is the most common of all rhinos and consists of two subspecies, with the northern subspecies being rarer than the southern. The northern subspecies may have as few as 50 remaining world wide.

The Northern White Rhino formerly ranged over parts of north-western Uganda, southern Chad, south-western Sudan, the eastern part of Central African Republic, and north-eastern Democratic Republic of the Congo (DRC). The only confirmed population today occurs in north-eastern DRC

Paris Motor Show

September 5th 2007 11:25
The Mondial de l'Automobile (Paris Motor Show in English) is a bi-annual auto show in Paris. Held in late September, it is one of the most important auto shows, often with many new production automobile and concept car debuts. The show was the first motor show in the world, started in 1898 by industry pioneer, Albert de Dion. The show takes place in Paris Expo in Porte de Versailles. The Mondial is scheduled by the Organisation Internationale des Constructeurs d'Automobiles, which considers it a major international auto show.

Until 1986 it was called Salon de l'Auto. It took the name Mondial de l'Automobile in 1988

Dubai City

September 3rd 2007 10:39
The Dubai government's decision to diversify from a trade-based but oil-reliant economy to one that is service- and tourism-oriented has made real estate and other developments more valuable, resulting in the property boom from 2004–2006. Construction on a large scale has turned Dubai into one of the fastest-growing cities in the world.

The Burj Dubai is a super tall skyscraper currently under construction in the "New Downtown" of Dubai. Projected to be completed and occupied in 2008, the silvery glass-sheathed concrete building will restore the title of Earth's tallest structure to the Middle East — a title not held by the region since Lincoln Cathedral upset the four millennial reign of Egypt's Great Pyramid of Giza in 1311 AD
