Or at least the next best thing. The Earth Simulator, the most powerful supercomputer ever built, was designed for a single purpose: to create a virtual twin of our home planet. Before the Earth Simulator arrived, the fastest computer in the world was an American military machine that can perform 7.2 trillion calculations per second. The Earth Simulator runs at more than 35 trillion calculations per second, almost five times faster. In fact, it's as powerful as the next 12 fastest supercomputers in the world put together. Located at a vast, newly built facility in Yokohama, the Earth Simulator is the size of four tennis courts. The price tag? Around $350 million.
It was worth every penny. By plugging real-life climate data from satellites and ocean buoys into the Earth Simulator, researchers can create a computer model of the entire planet, then scroll it forward in time to see what will happen to our environment. Scientists have already completed a forecast of global ocean temperatures for the next 50 years, and a full set of climate predictions will be ready by year's end. Soon, instead of speculating about the possible environmental impact of, say, the Kyoto accord, policymakers will be able to plug its parameters into the virtual Earth, then skip ahead 1,000 years to get a handle on what effect those policies might have. That kind of concrete data could revolutionize environmental science. By digitally cloning the Earth, we might just be able to save it. via.

AUDIO – An audio (sound) wave is a one-dimensional acoustic (pressure) wave. When an acoustic wave enters the ear, the eardrum vibrates, causing the tiny bones of the inner ear to vibrate along with it, sending nerve pulses to the brain. These pulses are perceived as sound by the listener.
VIDEO – The human eye has the property that when an image is flashed on the retina, it is retained for some number of milliseconds before decaying. If a sequence of images is flashed at 50 or more images/sec, the eye does not notice that it is looking at discrete images. All video systems exploit this principle to produce moving pictures.

The amazing music composed by Bruno Coulais complements well with the amazing documentary; however, the lack of narration can be quite easily felt during the entire one and a half hour of the show - but then nothing is perfect to the satisfaction of everybody. Most of the show is filled with sounds from insects while occassionally accompanied by contextual music and sound effects. However, not all insects and their sounds are familiar unless you are a zoologist specializing in arthropods. This is a highly recommended documentary for all ages because of the uniqueness of its contents.

First open the movie in VirtualDub. Now, in the Audio menu, make sure the Direct Stream Copy option is selected. After the options are saved, select the portion you want to extract. Just move the Timeline slider until you reach the starting point of the song you want to extract. Press HOME to mark the start position of the song. Now move the slider until you reach the end position of the song you want to extract. Press END to mark this option. Click on File > Save Wav and enter the location where you want to save this file as Temp.wav. As WAV files are uncompressed format, this will be a huge file but don't worry, you can convert this file to MP3 later, using encoders such as RazorLame.

Set in the not so far future, Neuromancer is about a wannabe ubergeek named Case. He lives in a world that is saturated with ubiquitous technology. Cities are no longer metropolises - they have developed into urban sprawls. People no longer log in to the Internet - they use neural jacks to directly plug in their brains so that they can visualize whatever they encounter inside the "Matrix", today's version of the Internet. Although the book does not portray a commoner's lifestyle in detail, it shows how society is surviving under complex atmosphere created due to corporate pressure because in Neuromancer, multinational companies are the true rulers of the society.
Case lives in the backyards of Chiba, a suburb of Tokyo. It is a dark world - the streets are hangouts for sex agents, drug addicts and brokers selling blackmarket body parts. Case used to be a talented hacker, working for companies who employed him in order to steal valuables of other companies. In one of his missions, Case tried to steal money from his employers, who then took revenge by damaging Case's brain and his central nervous system rendering him unable to gain access to the matrix. The matrix is everything for case - and seeing no future without being able to jack in again, he comes to Chiba with hopes of repairing his damaged body. After a lot of unsuccessful attempts at buying replacement parts, Case runs out of money, thus forcing himself to live at the backstreets of Chiba.
The story begins when a person called Armitage offers him job as a hacker - with an offer to repair his body parts. Case instantly agrees and teaming up with Molly, also recruited by Armitage, he is all set to begin his new life. Molly is not an ordinary girl - her body is cybernetically enhanced with biometric surgeries of all kinds. Her nails contain hidden razors, her reflex system is faster and her face is enhanced so as to protect her eyes. She is swift for a warrior, skilled for a number of combats - which is why she's been dubbed a street-samurai. As the story unfolds, Case and Molly develop a personal relationship and go on a number of adventures around the world working for Armitage. Later they begin to secretly inquire into the life of Armitage and come up with strange conclusions.
I am not a fan of science fiction stories and I can count the number of SciFi stories I have read so far (The Time Machine, Contact and Brave New World). Unlike the other three, this book portrays a strong and dark world that could be waiting human civilization in the very near future. I am referring to the society, depicted in Neuromancer, which is surviving directly under multinational companies. Today, governments are powerful enough to control the companies (big or small) within their jurisdiction - but there is limited or no law to check a manufacturing company from researching, practicing and selling new technologies. In fact this very limitation of the law could be the hidden key to large companies, with resource and expertise, to grow their technological prowess in the market. So how long will it take before large corporations begin to own technologies that surpass any government power? As such, would a company still want to remain under a government or wouldn't it want to become the new government itself? Neuromancer, thus, has an extremely valid plot that is convincing to its readers from every angle - be it the description of the Matrix, the street-samurai, or Wintermute (an AI that rivals the humans who created it).
I wonder whether The Matrix has anything to do with Neuromancer, especially because of the strange resemblance of cyberspace in both of these works. Wachowski Brothers could indeed reply!
