wolfram alpha search engine (source-http://ambigram24.blogspot.com/)

 " Wolfram(http://www.wolframalpha.com)" is a computational search engine which gives statistical information on a query.My friend abhijeet had suggested this website.He was very impressed with the search engine, so i thought to give it a try.

I searched 'VNIT' in the engine,i was not impressed at the beginning for the simple fact that ,it portrays the information in detailed and precise form but i felt what's so great about that.

Then i browsed the website i saw that its not just a simple search engine which puts data in precise and detailed format.

Wolfram|Alpha introduces a fundamentally new way to get knowledge and answers—
not by searching the web, but by doing dynamic computations based on a vast collection of built-in data, algorithms, and methods.

It analyses data and gives conclusions.It has revolutionized the way of computing.Though it is not presently threat to google,but it might give a good competition in future.

For years Google has been there for us, serving to there level best. From

Energy-saving magnetic PCs, soon

Energy-saving magnetic PCs, soon - Times Of India: (source-TOI)

Coming soon- Magnetic computers which may use far less energy, say scientists.

A team at the University of California, which is developing such computers, claims that the future machines will rely on magnetic microprocessors which consume the least amount of energy allowed by the laws of physics.

Today's silicon-based microprocessor chips rely on electric currents, or moving electrons, that generate a lot of waste heat.

But microprocessors employing nanometer-sized bar magnets - like tiny refrigerator magnets - for memory, logic and switching operations theoretically would require no moving electrons, say the scientists.

Such chips would dissipate only 18 millielectron volts of energy per operation at room temperature, the minimum allowed by the second law of thermodynamics and called the Landauer limit. That's one million times less energy per operation than consumed by today's computers.

Brian Lambson , who led the team, said: "Today, computers run on electricity, by moving electrons around a circuit, you can process information. A magnetic computer, on the other hand, doesn't involve any moving electrons.

"You store and process information using magnets, and if you make these magnets really small, you can basically pack them very close together so that they interact with one another. This is how we are able to do computations, have memory and conduct all the functions of a computer."

TR35: Gert Lanckriet, 34 - Technology Review

TR35: Gert Lanckriet, 34 - Technology Review:

Is Lady Gaga's "Born This Way" a happy song? Is "Bohemian Rhapsody" sad? Gert Lanckriet wants computers to be able to tell. Then people could search for tunes that match a particular mood or instrumental style, and an online store could make better recommendations.

Lanckriet, an associate professor in the Department of Electrical and Computer Engineering at the University of California, San Diego, started by having his computers analyze a collection of 500 popular songs that human judges had categorized in six ways—by genre and tempo, for example. When fed a new piece of music not in the database, the computer uses that training to infer how a human would characterize it. Lanckriet continues to train the system through a Facebook game called Herd It, launched in 2009. Players listen to snippets of music and win points if they agree with the majority of their fellow users; the results are fed into Lanckriet's software.

After the software gets some more fine-tuning, Lanckriet plans to let it crawl the Web like a search engine, automatically classifying the huge amount of music available online. He's also exploring how to use the sensors in smart phones to cue up exactly the sort of music someone is in the mood for. If the phone's accelerometer detects that the user is exercising, it could choose something energetic, while sitting in a quiet room at night might lead it to choose something mellower.

Chinese Scientists Plan to Pull an Asteroid into Orbit Around Earth

Chinese Scientists Plan to Pull an Asteroid into Orbit Around

Earth

Last week Chinese scientists wanted to divert an asteroid away from Earth. This week, they want to pull one into orbit around the Earth. What’s possible objections could anyone have to this idea?

The notion stems from a phenomenon the researchers from Tsinghua University in Beijing noticed from time to time with Jupiter. Every now and then our solar systems biggest planet pulls in an object from space, which orbits the planet for a time before jetting off into interplanetary space again.

We could do something similar with a number of near earth objects (NEOs) that will pass near Earth in the coming years and decades. None of these objects will pass close enough to be naturally captured by Earth’s gravity, but a few will come so close that a small nudge in the right direction would put them in orbit--likely a temporary orbit--around Earth.

The idea isn’t simply to flirt with cataclysmic danger, but to bring a small object (they suggest a 10-meter object called 2008EA9 that will pass nearby in 2049) into a loop around the Earth so we can study it closely for a few years. If we can get the art of capturing asteroids orbitally down to a science, we could use it to temporarily make asteroids into Earth-bound satellites (orbiting at about twice the distance of the moon), mine them for minerals, and then send them on their ways.

Google sketch up

Google sketch up is the new application of Google which has appeared very interesting to me, as always google applications have lived up to their expectations.Google sketch up is an open source version  to well known CAD ,software used to create three dimensional images and design.Guess what it is easier to use,i can guarantee you that if you sit with for a half an hour ,you will be able to make your own 3D design.It is a small sized app and very convenient to make 3D design.Once a design is made,the designer has the flexibility to make images of the design in different angles in JPEG format. The various tools are easy to understand ,there are templates available to use directly ,saving your time.There are measuring tools ,just in case you want your design to have proper dimension ratio.

This is one of the design ,i came across

It is easy to make a design in sketch up, the few tools which might be new to user are 3 D projection tool and offset tool .

you just use projection tool to drag in the direction of projection needed

Apart from this others are self understandable .

People all over the world have used this software to design things which are not technical, just to pass their time.It has become the new 'Paint'...

Hats off to Google for making such a dynamic and useful application...I personally feel everyone should try this application once.

Mobile Phone History | Invention story of Mobile Phones

Mobile Phone History | Invention story of Mobile Phones

Mobile Phones have proved themselves to be one of the greatest gifts to the mankind. They have become an indispensible part of our lives. But going back in time, owning a mobile phone was confined to members of affluent class. All thanks to cost cutting techniques and innovations over a period of time; mobile phones are now affordable for everyone. With a plethora of mobile phones sets flooding the market, they are not just catering to the needs but are acting as status symbols for many.

Origin of this gadget is quite interesting. Starting from bulky mobiles phones which were as long and heavy as one’s forearms, to ultra thin and techno savvy handsets, mobiles phones have covered a long way so far. It all started with the basic telephony. Alexander Graham Bell was the first one to patent telephone in the year 1876. This technology was developed using the equipment designed for telegraph. Calls were connected with the help of operators. And a pillar of the mobile telephony came into existence when Charles Stevenson invented radio communication in early 1890s for keeping contacts with the offshore lighthouses. Marconi transmitted signals over the distance of 2 kms in year 1894. And Fessenden capably broadcasted music through radio by 1906.

And the following development was merger of radio telephone technology. In 1926, first class passenger trains, running from Berlin to Hamburg used the technology. These radio telephones were also used for air traffic safety as well as in the passenger airplanes. At the time of Second World War, German tanks made great use of these radio telephones too.

Two way radios was an ancestor of the mobiles phones. These radios also known as the mobile rigs, were fixed police cruisers, ambulances, taxicabs before advent of handheld mobile phones. Since the mobile radios were given connection to telephone network, one could not dial these from the home phones. And slowly this technology gained popularity among the mobile radio users.

Later versions of these radio phones incorporated cigarette lighter plugs and were called bag phones. Fixed in the vehicles, these gadgets were either used as portable two way radios or mobile phones. And then in 1940s, Motorola came with new developments in mobile phones. And this is how Walkie Talkie was born. Large, bulky and battery operated, this Handie Talkie soon found a way to US military.

Another turning point came in the history of mobile phones when the base station for mobile phones came into being. Engineers from Bell Labs developed the base stations in 1947. The same year, W. Rae Philip and Douglas H. Ring developed hexagonal cells for these mobile phones. But an engineer, Porter from Bell Labs, suggested positioning of the cell towers at corners of hexagons instead of center. He also argued for the directional antennas, for transmitting or receiving the signals in the three directions, into adjacent hexagon cells.

In 1956, Ericsson Company released the earliest full automatic cellular phone system called MTA in Sweden. Though this gadget was operated automatically but due to its bulkiness, could not really hold the users interest for long. It is surprising to hear that this mobile phone weighed around 40 kgs back then. And then improved and lighter version of the same phone was introduced in 1965. This was known as MTB and used the DTMF signaling.

Soon in 1957, Leonid Kupriyanovich developed experimental model of wearable mobile phones in Moscow, operating with the help of base station. This young engineer had earlier developed the radio phone known as LK-1. The battery life of the wearable mobile phone by the young inventor lasted for around 20-30 hours. Weighing 3 kg, it worked within the distance of 20 to 30 km from the station. Later he patented the mobile phones and also came up with a version of pocket mobile phone that was just of 0.5 Kgs in the same year.

Then again automatic pocket mobile phone was developed in 1966 at Bulgaria. Called RAT-0.5, phone coordinated with the base station known as RATZ-10. And further developments in the field of the cellular phones were witnessed in 1967. It was decided that every mobile phone would be catered to a base station throughout its life. Though this was not that novel concept, need of one base station at least broke continuity of the automatic services to the mobile phones. After three years, in 1970, another engineer Ames E. Joel invented automatically operated call handoff technology. This system allowed the mobile phones to pass through cell areas while making a phone call without any loss of conversation. This was the time when the mobile user could use the gadget without any disturbance.

Further in year 1971, AT&T Incorporation projected mobile phone service that was approved by FCC later. Another development in the history of mobile phones was registered with ARP network’s success launched in Finland. It was the earliest commercial cellular phones and was known as Zero Generation mobile network.

Invention of mobile phones that closely resembles today’s mobile phones is credited to Martin Cooper, employer and researcher of Motorola. He initially developed cellular phone named Motorola Dynatac in 1973. With 5 inches width and 9 inches length, this 2.5 pounds weighing phone carried around 30 circuit boards in it. With recharge time of around 10 hours, talk time of 35 minutes, this phone gave comfortable talking experience to the users. One could listen, dial and talk on this mobile phone but what was missing was display screen. With passing time, refinements were made and these mobile phones improved by leaps and bounds.

With introduction of Global System for the mobile communications, radio spectrum could be used effectively. The technology gave great voice quality, international roaming facilities along with compatibility with ISDN systems. And further for providing coverage to the remote areas that ISDN, GSM and cellular phones could not offer, satellite phones came into being. Base station for the satellite phones were built in the geostationary satellites. And now there is no place on the planet that is untouched by the mobile phones.
