Palm Islands Dubai

 ^ Due to its immense scale and unique shape, The Palm, Jumeirah and The Palm, Jebel Ali are visible from space with the naked eye. 

The creation and development of The Palm is an unparalleled feat of design and engineering. The Palm is destined to be like no other place on earth.
.
.
.


^ The brilliance of The Palm is both in its tribute to the date palm tree, referred to as 'bride of orchard', and in its ideal geometry for creating maximum beach frontage.

Each island will add 60 kilometres of shoreline to Dubai, increasing the UAE's beachfront by an extraordinary 166%.
.
.
.


^ Rocks weighing a total of 7 million metre cubed (per island) are being brought in from sixteen different quarries throughout the United Arab Emirates. 
The Palm comprises approximately 100 million cubic metres of sand and rock.
.
.
.


^ If all the fill materials used to build one Palm island were placed end to end, a wall two meters high and half a metre thick could circle the world three times.
.
.
.


^ Dredges play a prominent role in building The Palm. Sand is first dropped into place and piled at a specific angle of repose, ensuring it will hold its place.

.
.
.


^ After the initial dumping of sand, a dredger brings the sand level to the surface with a process called "rainbowing", which literally sprays the sand into proper position.
.
.
.


^ The Crescent surrounds the island and acts as a breakwater - able to withstand a 4m wave. It is built from the bottom up, beginning with the sand, geotextile fiber, small rocks, and then medium sized rocks, once above water.
.
.
.


^ Expert Divers examine rock placement underwater to ensure correct positioning. Divers are also used to review placement of geotextile.

Over 100 studies from transportation, marina design and water supply to technology and civil works have been completed to assess and ensure The Palm's feasibility.
.
.
.


^ Where do all the trees that the islands will require come from? 
Over 12,000 Palm trees will be grown on a nursery in Jumeirah, Dubai.
.
.
.


^ From crabs to shell fish, reefs, coral and rocks, the Arabian Gulf is full of marine life. The Palm will help stimulate its development by adding nutrient rich materials. Residents and visitors will delight in snorkelling, scuba and diving in this rich resource.

Fun facts about engineering, science and technology

       
 1.      220 million tons of old computers and other technological hardware are trashed in the  United            States each year.
2.      A diamond will not dissolve in acid. The only thing that can destroy it is intense heat.
3.      According to Moore's Law, microchips double in power every 18 to 24 months.
4.      Albert Einstein won the Nobel Prize for physics in 1921.
5.      Although the famous first flight at Kitty Hawk took place on December 17, 1903, the secretive Wright Brothers did not demonstrate the technology to the broader public until August 8, 1908.
6.      As of early 2009, there have been 113 space shuttle flights since the program began in 1981.
7.      Bill Clinton's inauguration in January 1997 was the first to be webcast.
8.      Chuck Yeager blasted through the sound barrier at Edwards Air Force Base in 1947.
9.      Einstein received the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect, the phenomenon by which electrons are knocked out of matter by electromagnetic radiation such as light.
10.   In 1901, the Spanish engineer Leonar do Torres-Quevedo was responsible for the earliest developments in the remote control with his Telekine that was able to do "mechanical movements at a distance."
11.   In their Miyagi, Japan laboratories, beginning in 1924, Professor Hidetsugu Yagi and his assistant, Shintaro Uda, designed and constructed a sensitive and highly-directional antenna using closely-coupled parasitic elements. The antenna, which is effective in the higher-frequency ranges, has been important for radar, television, and amateur radio.
12.   Marie Curie was the first person to win two Nobel Prizes for Science
13.   No one has received more U.S. patents than Thomas Edison – 1,093 to be exact.
14.   On 11 July 1962, France received the first transatlantic transmission of a TV signal from a twin station in Andover, Maine, USA via the TELSTAR satellite.
15.   On 9 June 1906 the Winnipeg Electric Railway Co. transmitted electric power from the Pinawa generating station on the Winnipeg River to the city of Winnipeg at 60,000 volts. It was the first year-round hydroelectric plant in Manitoba and one of the first to be developed in such a cold climate anywhere in the world.
16.   On December 12, 1901, a radio transmission of the Morse code letter 'S' was broadcast from Poldhu, Cornwall, England, using equipment built by John Ambrose Fleming.
17.   One third of the world population has never made a telephone call.
18.   Samuel Morse, the inventor of the Morse code, was a painter as well. One of his portraits is of the first governor of Arkansas and hangs in the governor’s mansion of that state.
19.   Telecommunications satellites, and other satellites that need to maintain their position above a specific place on the earth, must orbit at 35,786 kilometers and travel in the same direction as the earth's rotation.
20.   The circumference of the earth is about 25,000 miles. Its surface area is about 200,000,000 square miles and it weighs 6,588,000,000,000,000,000,000 tons.
21.   The Ericsson Company first produced cellular phones in 1979.
22.   The first computer mouse was introduced in 1968 by Douglas Engelbart at the Fall Joint Computer Expo in San Francisco.
23.   The first Japanese-language word processor was developed in Tokyo between 1971 and 1978.
24.   The first laser was made in California in 1960.
25.   The first two video games copyrighted in the U.S. were Asteroids and Lunar Lander in 1980.
26.   The Internet is the fastest-growing communications tool ever. It took radio broadcasters 38 years to reach an audience of 50 million, television 13 years, and the Internet just 4 years.
