Although the system is still new, it has already generated massive interest and excitement among technology pundits and internet watchers.

Computer professionals think that the new search engine could be an extraordinary jump in the evolution of the internet. Nova Spivack, an internet and computer expert, advised that Wolfram Alpha could prove equally as popular as Google. "It is really impressive and significant," he wrote. "In fact it may be as important for the web (and the world) as Google, but for a different purpose."

Tom Simpson, of the blog www.convergenceofeverything.com, said: "What are the wider implications exactly? A new paradigm for using computers and the web? Probably. Emerging artificial intelligence and a step towards a self-organizing internet? Possibly... I think this could be big."

Wolfram Alpha will not only provide a direct answer to questions such as "how high is Mount Everest?", but it will additionally create a organized page of related information – all properly annotated – such as geographical location and nearby towns, and other mountains, complete with charts and charts.

The real innovation, however, is in its ability to figure information out "on the fly", according to its British inventor, Dr Stephen Wolfram. If you ask it to compare the height of Mount Everest to the length of the Golden Gate Bridge, it will tell you. Or ask what the weather was like in London on the day John F. Kennedy was assassinated, it will cross-check and provide the answer. Ask it about D sharp major, it will play the scale. Type in "10 flips for four heads" and it will determine that you need to know the probability of coin-tossing. If you want to know when the next solar eclipse over Chicago is, or the precise current location of the International Space Station, it can work it out.

Dr. Wolfram, an award-winning physicist who is based) in America, added that the information is "curated", meaning it is assessed first by experts. This means that the weaknesses of sites such as Wikipedia, where doubts are cast on the information because anyone can contribute, are removed. It is based on his best-selling Mathematica software, a standard tool for scientists, engineers and academics for deciphering complex maths.

"I\'ve wanted to make the knowledge we\'ve accumulated in our civilization computable," he said last week. "I was not sure it was possible. I\'m a little surprised it worked out so well."

Dr. Wolfram, 49, who was educated at Eton and had completed his PhD in particle physics by the time he was 20, added that the launch of Wolfram Alpha later this month would be just the beginning of the project.

"It will understand what you are talking about," he said. "We are just at the beginning. I think we\'ve got a reasonable start on 90 per cent of the shelves in a typical reference library."

The engine, which will be free to use, computes by drawing on the knowledge of the internet, as well as non-public databases. Dr. Wolfram said he expected that about 1,000 employees would be required to maintain its databases current with the most recent discoveries and information.

Wolfram Alpha has been created with professionals and intellectuals in mind, so its grasp of popular culture is, at the moment, comparatively poor. The term "50 Cent" caused "absolute horror" in tests, for example, because it confused a discussion on money with the American rap artist. For this reason alone it is unlikely to provide an immediate threat to Google, which is working on a similar type of search engine, a version of which it launched last week.

"We have a lot amount of popular culture facts," Dr Wolfram said. "In some senses popular culture information is much more shallowly computable, so we can figure out who\'s related to who and how tall people are. I fully expect we will have masses of popular culture information. These are linguistic horrors because if you put in books and music a lot of the names collide with other ideas."

He added that to assist with that Wolfram Alpha would be using Wikipedia\'s popularity index to decide what users were likely to be interested in.

With Google now one of the world\'s top brands, worth $100bn, Wolfram Alpha has the potential to become one of the biggest names on the planet.

Dr. Wolfram, however, did not rule out working with Google in the future, as well as Wikipedia. "We\'re working to partner with all possible organisations that make sense," he said. "Search, narrative, news are complementary to what we have. Hopefully there will be some great synergies."
