The Brain



The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.

1. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever
wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the superspeedy
movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.


2. The brain operates on the same amount of power as 10watt
light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the
mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.


3. The human brain cell can hold 5 times as much information as the EncyclopediaBritannica. Or any other encyclopedia for that matter. Scientists have yet to settle on adefinitive amount, but the storage capacity of the brain in electronic terms is thought tobe between 3 or even 1,000 terabytes. The National Archives of Britain, containing over
900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.

The World Islands






  • The World involves the creation of over 300 man made islands that are designed to represent the world map



  • The vision for The World project was provided by His Highness General Sheikh Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai and UAE Defence Minister and was officially released on September 21, 2003



  • The islands will be built in the shape of the world map and consist of four protective breakwaters on the outer perimeters to provide shelter from long and cross-shore waves. The inner breakwaters will be a submerged reef and the outer breakwaters will be above water



  • Located just off the coast of Dubai in the United Arab Emirates, The World is located 4km off shore from a point halfway between Port Rashid and The Palm, Jumeirah





  • Construction of The World commenced in September 2003, after many years of research. The project is scheduled to be completely raised from the sea in 2008.



  • Investors will have the freedom to create their own personal vision on the islands for private or commercial use, whether it is for leisure, residential or tourist developments. The 300 islands will be offered for sale on a freehold basis to selected investors only



  • Nakheel will hand over the islands to the investors once the land has been reclaimed in 2008.



  • The World will measure approximately 9km in length and 7km in width. It will cover over 9,340,000 square metres, and will add 232 kilometres of beachfront to Dubai’s coastline.



  • All of the islands will range from 150,000 sq feet to 450,000 sq feet in size, with the average island measuring approximately 300,000 square feet



  • 326 million cubic metres of sand will be used to form the islands



  • 32 million tons of rock will be used to construct the breakwater



  • The islands prices range from US$ 10 million – 45 million



  • The average distance between islands is 50-100 metres, with an average depth of water in the navigation channels of at least 5 metres



  • The World will be a sophisticated network of islands – Nakheel will integrate a series of waterways, canals and lakes to enhance the overall design




  • All 300 islands will only be accessible by marine or air transport, with world-class marinas to berth boats, yachts and cruise liners. 2 mainland marinas will service The World. 4 hub islands in The World will service the islands.



  • Construction on The World is round-the-clock, 24 hours a day, seven days a week



  • The main Contractors for The World are Van Oord ACZ Marine Contractors Gulf FZE – Dubai who are responsible for land reclamation, dredging works and the breakwaters. This is the largest project Van Oord has undertaken in the region



  • The jumbo trailers being used to build The World can handle 20-25 thousand cubic metres of sand at any one time and require a water depth of at least 12 metres to operate.
  • Crop Circles

    What are Crop Circles?

    Crop circles are patterns that appear in fields. The pattern is created when certain areas of the crops are tamped down, but others are left intact. The edge is so clean that it looks like it was created with a machine. Even though the stalks are bent, they are not damaged. Most of the time, the crop continues to grow as normal.

    Sometimes, the patterns are simple circles. In other instances, they are elaborate designs consisting of several interconnecting geometric shapes.

    Farmers have reported finding strange circles in their fields for centuries. The earliest mention of a crop circle dates back to the 1500s. A 17th-century English woodcut shows a devilish creature making a crop circle. People who lived in the area called the creature the “mowing devil.”

    Mentions of crop circles were sporadic until the 20th century, when circles began appearing in the 1960s and ’70s in England and the United States. But the phenomenon didn’t gain attention until 1980, when a farmer in Wiltshire County, England, discovered three circles, each about 60 feet (18 meters) across, in his oat crops. UFO researchers and media descended on the farm, and the world first began to learn about crop circles.

    By the 1990s, crop circles had become something of a tourist attraction. In 1990 alone, more than 500 circles emerged in Europe. Within the next few years, there were thousands. Visitors came from around the world to see them. Some farmers even charged admission to their mysterious attractions.

    Crop Circle Designs

    Crop circles are not just circles,they can come in many different shapes. The most basic (and the most common) crop circle is the single circle. Circles may also come in sets of two (doublets), three (triplets) or four (quadruplets). Circles also may be enclosed in a thin outer ring.

    The stalks inside a crop circle are typically bent into what is known as a swirl pattern, and the circles may spin clockwise or counterclockwise. In patterns with several circles, one circle may spin clockwise and another counterclockwise. Even a single circle may contain two “layers” of stalks, each spinning in a different direction.

    Crop circles can range in size from a few inches to a few hundred feet across. Most early crop circles were simple circular designs. But after 1990, the circles became more elaborate. More complex crop patterns, called pictograms, emerged. Crops can be made to look like just about anything smiling faces, flowers or even words. Crop circles are sometimes unique designs, but they can also be based on ancient motifs.

    Most circles are concentrated in the south of England, primarily in the counties of Hampshire and Wiltshire. Many of them have been found near Avebury and Stonehenge, two mystical sites containing large stone monuments.

    But crop circles are not confined to England. They have been spotted in the United States, Canada, Australia, Japan, India and other parts of the world.

    The “season” for crop circles runs from April to September, which coincides with the growing season. Circles tend to be created at night, hiding their creators (human or otherwise) from curious eyes.

    Crop circles can be found in many different types of fields wheat, corn, oats, rice, oil-seed rape, barley, rye, tobacco even weeds. Most circles are found in low-lying areas close to steep hills, which may explain the wind theory of their creation
