history of vedic math

Tirthaji and the rediscovery of Vedic Mathematics

The ancient system of Vedic Mathematics was rediscovered from the Indian Sanskrit texts known as the Vedas, between 1911 and 1918 by Sri Bharati Krsna Tirthaji (1884-1960). At the beginning of the twentieth century, when there was a great interest in the Sanskrit texts in Europe, Bharati Krsna tells us some scholars ridiculed certain texts which were headed 'Ganita Sutras'- which means mathematics. They could find no mathematics in the translation and dismissed the texts as rubbish. Bharati Krsna, who was himself a scholar of Sanskrit, Mathematics, History and Philosophy, studied these texts and after lengthy and careful investigation was able to reconstruct the mathematics of the Vedas. According to his research all of mathematics is based on sixteen Sutras, or word-formulae.

Bharati Krsna wrote sixteen volumes expounding the Vedic system but these were unaccountably lost and when the loss was confirmed in his final years he wrote a single book: Vedic Mathematics, currently available. It was published in 1965, five years after his death.

Using VERTICALLY AND CROSSWISE you do not need to the multiplication tables beyond 5 X 5.

• Suppose you need 8 x 78 is 2 below 10 and 7 is 3 below 10.
  Think of it like this:
  
  The answer is 56.
  The diagram below shows how you get it.
  
  You subtract crosswise 8-3 or 7 - 2 to get 5,
  the first figure of the answer.
  And you multiply vertically: 2 x 3 to get 6,
  the last figure of the answer.
  That's all you do:
  See how far the numbers are below 10, subtract one
  number's deficiency from the other number, and
  multiply the deficiencies together.
• 7 x 6 = 42
  
  Here there is a carry: the 1 in the 12 goes over to make 3 into 4.

math

Use the formula ALL FROM 9 AND THE LAST FROM 10 to perform instant subtractions.

• For example 1000 - 357 = 643We simply take each figure in 357 from 9 and the last figure from 10.
  
  So the answer is 1000 - 357 = 643
  And thats all there is to it!
  This always works for subtractions from numbers consisting of a 1 followed by noughts: 100; 1000; 10,000 etc.
• Similarly 10,000 - 1049 = 8951
  
• For 1000 - 83, in which we have more zeros than figures in the numbers being subtracted, we simply suppose 83 is 083.So 1000 - 83 becomes 1000 - 083 = 917

corruption

280 लाख करोड़ का सवाल है ...
भारतीय गरीब है लेकिन भारत देश कभी गरीब नहीं रहा"* ये कहना है
डाइरेक्टर का. स्विस बैंक के डाइरेक्टर ने यह भी कहा है कि भारत का लगभग 280 लाख करोड़ रुपये उनके स्विस बैंक में जमा है. ये रकम
इतनी है कि भारत का आने वाले 30 सालों का बजट बिना टैक्स के बनाया जा सकता है. या यूँ कहें कि 60 करोड़ रोजगार के अवसर दिए जा सकते है. या यूँ भी कह सकते है कि भारत के किसी भी गाँव से दिल्ली तक 4 लेन रोड बनाया जा सकता है. ऐसा भी कह सकते है कि 500 से ज्यादा सामाजिक प्रोजेक्ट पूर्ण किये जा सकते है. ये रकम इतनी ज्यादा है कि अगर हर भारतीय को 2000 रुपये हर महीने भी दिए जाये तो 60 साल तक ख़त्म ना हो. यानी भारत को किसी वर्ल्ड बैंक से लोन लेने कि कोई जरुरत
नहीं है. जरा सोचिये ... हमारे भ्रष्ट राजनेताओं और नोकरशाहों ने कैसे देश को लूटा है और ये लूट का सिलसिला अभी तक 2011 तक जारी है. इस सिलसिले को अब रोकना बहुत ज्यादा जरूरी हो गया है. अंग्रेजो ने हमारे भारत पर करीब 200 सालो तक राज करके करीब 1 लाख करोड़ रुपये लूटा. मगर आजादी के केवल 64 सालों में हमारे भ्रस्टाचार ने 280 लाख करोड़ लूटा है. एक तरफ 200 साल में 1 लाख करोड़ है और दूसरी तरफ केवल 64 सालों में 280 लाख करोड़ है. यानि हर साल लगभग 4.37 लाख करोड़, या हर महीने करीब 36 हजार करोड़ भारतीय मुद्रा स्विस बैंक में इन भ्रष्ट लोगों द्वारा जमा करवाई गई है. भारत को किसी वर्ल्ड बैंक के लोन की कोई दरकार नहीं है. सोचो की कितना पैसा हमारे भ्रष्ट राजनेताओं और उच्च अधिकारीयों ने ब्लाक करके रखा हुआ है. हमे भ्रस्ट राजनेताओं और भ्रष्ट अधिकारीयों के खिलाफ जाने का पूर्ण अधिकार है.हाल ही में हुवे घोटालों का आप सभी को पता ही है - CWG घोटाला, २ जी स्पेक्ट्रुम घोटाला , आदर्श होउसिंग घोटाला ... और ना जाने कौन कौन से घोटाले अभी उजागर होने वाले है ........आप लोग जोक्स फॉरवर्ड करते ही हो. इसे भी फॉरवर्ड करो.

camera

It is next to impossible to capture a photo without a camera. A camera is a device, which enables the recording of still and moving photographs within seconds. Without camera, it was never possible to capture good memories.

Camera was first designed by Joseph N. Niepce, who was from France, a retired Military Officer. He invented the first camera in 1826 in France. His camera known as "Obscura" had two wooden boxes out of which one box had a lens and the other had a screen, which was green in color. He then invented a diaphragm, which helped in the clarity of the image by sharpening the image.

The first discovery of the camera was made by a German Mathematician, Friedrich Risner. As there were more and more developments in the technology of camera, this led to improvement in the quality of pictures, film, flash and color pictures. With all these improvements and the developments in the camera, today we are able to see our past in our present. If there were no camera to capture our past, it would have been simply impossible to record our memories and moments of the past.

Alhazen was the person, who invented the first Pinhole Camera, also known as "Camera Obscura". It made the people know the true reason as to why the image often was upside down. Joseph N. Niepce made the first photographic image. The main idea of Joseph was to capture the image by making the light draw the picture.

With many inventors, there was a development of a modern photography. In 1829, it was Louis Daguerre in partnership with Joseph N. Niepce, who made a major improvement in photography. However, soon after the death of Joseph N. Niepce, Louis took over the charge to develop the most modern photography, which was named with his name as daguerreotype. He together with the son of Niepce sold its right to the government of France. He then gained a wide popularity and subsequently, there were as many as seventy photo studios developed in the city of New York.

new printer

 

Lexmark's new concept combines style, speed and elegance into one single all in one inkjet printer, termed the Genesis.

Utilising Flash Scan technology, the Genesis produces prints incredibly quickly and switches between print and scan functions in the blink of an eye. The scanning process is said not to last any longer than three seconds, based on the premise that your Operating System is up to date, your PC is equipped with an up to date specification in terms of hardware and the usage of character recognition software.

The Lexmark Genesis looks smart in its upright position, made even more slick by posessing a 4.4 inch color touch screen. The printer comes wirelessly enabled allowing you to access web technologies quickly, without the need for booting up your PC also. Browse through Twitter feeds, look through Facebook all from the printer itself, and upload scans to wherever you wish. This really is a printer for the current generation, which makes most other printers on the market look a bit cheap and dated.

The Australian team has rubbished a report that its two opening batsmen, Shane Watson and Brad Haddin, have been scrutinised for potential spot-fixing in the cricket World Cup match against Zimbabwe.
India's national wire service, the Press Trust of India, reported that the International Cricket Council has launched an investigation into the Australian pair because of their slow-scoring start in the match against Zimbabwe on February 21 - although it erroneously reported it related to the Australia-New Zealand match on February 25. Specifically, it alleged the spot-fixing element related to Australia only making five runs in the first two overs.
Australian team manager Steve Bernard, who last week had to contend with false stories in the Indian media that Australia captain Ricky Ponting had smashed a TV with his bat, said the story was "the silliest thing I've heard this week - and I've heard a lot of silly things since I've been here".

"I've just heard the story a moment ago and I'm not sure how to respond, except to say it would make a cat laugh. It's the most ludicrous thing I've ever heard in my life that a side can be 0-5 after two overs and that that's suspicious," Bernard said in Colombo, Sri Lanka, during a training session.
"At the start of any campaign, on a fresh track that the guys weren't used to, it took a bit of time [to adjust] but 260-odd was a pretty good score.
"I'm not sure if it's a make-up story by someone being a bit adventurous or a bit malicious . . . but I don't pay it any credence."
While Zimbabwe is ranked 11th in the world for one-day international cricket, its spinner Ray Price - who opened the bowling against Australia - is ranked the fourth-best bowler in the world in that format.
The PTI story quoted an unnamed source's that the ICC's Anti-Corruption and Security Unit (ACSU) was "taking no chances at all and all matches are under the scanner for possible indications that any spot-fixing has taken place", because of the fall-out of the guilty verdicts against Pakistan trio Salman Butt, Mohammad Amir and Mohammad Asif.
The ICC says it does not comment on any ACSU matter, including whether or not a match had or had not been investigated, as a matter of policy.
Haddin is expected to address the allegations after the Australian's team's training session is completed.

On/Off Paint on Switches

The On/Off paint turns any surface, even an entire wall, into an electric switch.

Designed by the French firm Quarks, the paint contains embedded electronic mechanisms which can be controlled by touch. The On/Off paint can be applied onto any normal material, and can function when covered with another coat of paint or even wallpaper. The switch can be any size desired- an entire wall, a selected spot, or a long narrow strip- and can be combined with any electrically controlled devices.

CBI arrests DB group MD Shahid Balwa in 2G scam

The Central Bureau of Investigation on Tuesday night arrested Dynamix Balwas (DB) group managing director Shahid Usman Balwa in connection with the 2G spectrum allocation scam. Highly-placed sources in the agency said Balwa was arrested from his Bandra residence in Mumbai this evening and would be taken to Delhi for being confronted with former Telecom Minister A Raja whose CBI custody was extended by two more days on Tuesday.on Tuesday. The arrest of Balwa comes two days before the 2G case comes up for hearing in the Supreme Court.
He would be produced before a magistrate tomorrow for transit remand to Delhi, the sources said.
Balwa-promoted DB Reality floated Swan Telecom. Raja allegedly helped Swan bag 2G licences for 13 circles, including Mumbai and Delhi, for Rs 1,537 crore but Swan sold 45 per cent shares to the UAE telecom giant Etisalat for approximately Rs 4,500 crore within months of bagging the spectrum.
The sources claimed CBI has evidence from the Income Tax department that Balwa, considered close to Raja, was instrumental in channelling the kickbacks allegedly received by the former telecom minister from the sale of 2G spectrum.
According to the sources, Balwa had allegedly helped the former Telecom Minister and some of his aides park the money in real estate sector.
Balwa is the fourth person to be arrested in 2G spectrum case after Raja, his former personal secretary R K Chandolia and former telecom secretary Siddharth Behura.
Chandolia and Behura were today sent by a court in Delhi to judicial custody on completion of their interrogation by CBI.

laser beam rocket

Laser Beam Rocket Launch

NASA is looking into the idea of using beamed energy to provide propulsion for space launches, which would allow for reusable rockets and cut payload costs.

The system, developed by Laser Motive, would involve focusing laser beams on a heat exchanger on board the rocket. The heat exchanger would transfer the energy to a liquid propellant such as hydrogen, which would covert it into a gas and force it out of a nozzle.

The thermal propulsion vehicles would be safer, since the potential for explosion would be eliminated and pieces would not need to drop off during flight. Since most of the complex components would remain on the ground, they would also be smaller, lighter, and less expensive to launch.

graphene

Physicists at the University of California have taken a major step towards developing a "spin computer" by successfully tunneling "spin injection" into graphene.
"An electron can be polarized to have a directional orientation, called 'spin.' This spin comes in two forms: 'up' or 'down' - and allows for more data storage than is possible with current electronics," explained UC associate professor Roland Kawakami.
"[Now], spin computers, when developed, would utilize the electron's spin state to store and process vast amounts of information while using less energy, generating less heat and performing much faster than conventional computers in use today."

According to Kawakami, graphene has amongst "the best" spin transport characteristics of any material at room temperature. 

"This makes it a promising candidate for use in spin computers. But [still], electrical spin injection from a ferromagnetic electrode into graphene is inefficient. 


"And an even greater concern is that the observed spin lifetimes are thousands of times shorter than expected theoretically. We would like longer spin lifetimes because the longer the lifetime, the more computational operations you can do."
To address the above-mentioned shortcomings, Kawakami and his colleagues inserted a nanometer-thick insulating layer - known as a "tunnel barrier" - in between the ferromagnetic electrode and the graphene layer.
"We found a 30-fold increase in the efficiency of how spins were being injected by quantum tunneling across the insulator and into graphene. [This is because the] insulator was operating like a one-way valve, allowing electron flow in one direction - from the electrode to graphene - but not the other," said Kawakami.


"[Clearly], the insulator helps to keep the injected spin inside the graphene, which is what leads to high spin injection efficiency. This counterintuitive result is the first demonstration of tunneling spin in graphene"

Russian scientists have won the Nobel Prize

Two Russian scientists have won the Nobel Prize for Physics for their work developing graphene

.
Andrei Geim

and Konstantin Novoselov demonstrated that carbon in this extremely thin form - just one atom thick - had exceptional properties originating in the world of quantum physics.
Konstantin Novoselov is a Royal Society Research Fellow at the University of Manchester in their Mesoscopic Research Group researching mesoscopic systems and nanostructures.
He was awarded the 2008 Europhysics Prize for the same discovery.
Andre Geim is a physicist who, as well as the discovery of graphene, is known for the development of gecko tape and demonstrations of diamagnetic levitation. He's also based at the University of Manchester.
Graphene is both the thinnest and the strongest material yet discovered. Geim and Novoselov extracted it from ordinary graphite, and used ordinary adhesive tape to obtain a flake of carbon with a thickness of just one atom.
"Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics," says the Royal Swedish Academy of Sciences.
"A vast variety of practical applications now appear possible including the creation of new materials and the manufacture of innovative electronics. Graphene transistors are predicted to be substantially faster than today’s silicon transistors and result in more efficient computers."
 

nucler

Nuclear reactors placed on the ocean floor may provide another option for nations determined to find alternative energy sources.

Developed by the French naval defense company DCNS, the reactors, known as Flexblue, could produce up to 250 megawatts of energy on the ocean floor. The Flexlblues are quite small, only 300 feet long, and include a nuclear reactor, steam turbine-alternator set, and equipment that carries the electricity to the coast.

Because the Flexblue plants would be hidden under water and several miles out to sea, they would be out of sight and, possibly, out of mind. Which may or may not be a good thing.

mouse

The new optical mouse is made of the same combination of Arboform and Biograde materials as those that were used in an eco-friendly keyboard released by Fujitsu last year. Arboform is based on a by-product of the paper making process, while Biograde is a biodegradable cellulose acetate. The mouse is also a bit more comfortable to use, since the outer shell is more elastic than other renewable materials.

plastic

By altering the wavelength of light, researchers have developed a method of welding transparent plastics together without the need for added absorbers.

Because soot particles must be used to absorb the radiation, conventional laser welding of plastic are usually limited to joining transparent plastic to black plastic. Researchers from Germany’s Fraunhofer Institute for Laser Technology studied a variety of transparent polymers to determine at what wavelengths they themselves absorbed radiation and then developed a laser that emits that particular wavelength, eliminating the need for soot or expensive alternatives.

The new technology could be applied in the production of microfluidic lab-on-a-chip devices.

solar

A new bridge proposal in Italy could utilize a Solar Wind concept, incorporating both wind and solar energy into its design.

The Solar Wind concept was conceived for a contest to repurpose unused viaducts in Southern Italy. Wind turbines installed in the spaces between the viaduct could provide 36 million kilowatt hours of energy, while a solar paneled roadway would provide an additional 11.2 million kilowatt hours. The concept even includes plans for solar powered greenhouses along the bridge and pull over spaces for travelers to enjoy the view.
