The Story of Gandhi

Author:Divakarbabu                                                                                               There was a boy. His name was Mohan.
He was studying in a school at Rajkot. He was not bright at studies, but was very fond of reading.
Once he read the story of Shravana. Shravana used to carry his old and blind parents in two baskets slung on a bamboo yoke. Mohan was deeply touched by his devotion to his old parents. He resolved to be like Shravana and serve his parents.
Once Mohan saw a play depicting the life of King Harishchandra, who lost his kingdom and suffered much for truth. Mohan was so deeply moved by this play that he was in tears. He decided never to swerve from the path of truth and be ever truthful and honest like Harishchandra.
In his childhood the young Gandhi was very timid. He feared to step in darkness, even in his own house. He feared ghosts and thieves and snakes. Rambha was a maid servant in his house. Once she said to Mohan: `Why are you so much fearful? Remember Rama! Rama will always protect you. Fear never encounters him who remembers Rama.'
Mohan was deeply impressed by these words. He took to reciting the name of Rama. His faith in Rama increased as he grew up. He remembered God and dedicated all his work to him. When he died his last words were `He Rama!'
Mohan's father, Karamchand Gandhi, was popularly known as Kaba Gandhi. In early years, he was the Diwan of Porbandar, and after that he became the Diwan of Rajkot. During his stay in Rajkot, his Parsee and Muslim friends often visited his house and discussed the good in their religions. Young Mohan, who quite often sat by father's side, heard these discussions. These debates created in him a real love for all religions.
Once the Inspector of schools came to visit his school. He wanted to test the boys, so he dictated a few English words to the boys. Mohan could not spell one of the words correctly. His teacher prompted him to copy that word from his neighbour's slate, but Mohan didn't. He did not like to cheat anybody, come what may. The result was that all the students except Mohan, spelt all the words correctly. The teacher scolded Mohan after the class and Mohan felt wounded. But deep inside him he knew that what he had done was right.
Mohan's full name is Mohandas Karamchand Gandhi. He was born in Porbandar, on the sea-coast of Saurashtra, on October 2, 1869. He did many great things when he grew up. Throughout the world he is now known as Mahatma Gandhi. He led us Indians to the non-violent fight for freedom and finally lay down his life for our sake. He ranks among the greatest teachers of all time like Buddha and Christ. He is the Father of our Nation. Every year, his birthday is celebrated throughout the world.
In those days, India was under the British rule. Once a boy told Mohan: `Do you know why the British are so strong and why they can rule over us? It is because they eat meat. If we become meat-eaters, like them, we will be able to drive them out.'
Mohan was convinced by this argument. But everybody in Mohan's house was strictly vegetarian, so he tried meat-eating outside. He did not disclose this secret to anybody, yet he was averse to telling a lie and deceiving the parents, so finally he decided not to touch meat again.
Mohan was taken to smoking also. For this he had to steal money and to incur debt. When the debt increased, he stole a piece of gold from one of the gold-bracelets that his brother wore and paid off the debt.
But soon after that, his heart was filled with remorse. He resolved never to steal again. He wrote down a confession of his crime on a piece of paper and put it in the hands of his father who was then sick.
The father read the letter and without uttering a word, tore up the paper with a deep sigh.
Mohan was deeply grieved. Tears rolled down his cheeks. He saw the power of truth. From that day, telling the truth became a passion with him. He loved his father more and more. He massaged his legs and served him in all possible ways.
But his father did not live long. He died when Mohan was only sixteen.
After passing his Matriculation examination, Gandhiji joined a college for further study, but his eldest brother decided to send him to England to become a barrister.
Now, Mother Putlibai asked Mohan to take a vow not to eat meat, not to drink and not to live an immoral life, Gandhiji took this vow, and boarded a steamer for England.
He arrived in London in October, 1888. At first, he had to face numerous handicaps. He almost starved until he found a good vegetarian restaurant. He learned Latin and French too, and finally passed his law examination. Now he was a barrister.
Then he returned to India. He was anxious to meet his mother and tell her that he had kept his vows in England. But as soon as he landed in Bombay, he heard that his mother had passed away only a few weeks ago! It was a terrible shock, yet he restrained himself.
Now Gandhiji started practice as a lawyer in Rajkot. After some time, an offer came to him to go to South Africa as a legal adviser to an Indian firm owned by a Gujarati Muslim businessman there. Gandhiji accepted the offer and in May 1893, he went to Natal in South Africa.
In South Africa, Indians were ill-treated and disgraced. They were called `Coolies'. Very soon Gandhiji too had his share of this experience. He was travelling in a train to Pretoria, in a first class compartment. On the way, a European passenger entered the compartment and found Gandhiji in it. He complained to the station master: `Take this coolie out and put him in a lower class!'. Gandhiji raised an objection that he had a first class ticket, but nobody heard him. A policeman pushed him out with his bag and baggages. The train left. Gandhiji spent the night shivering in cold, but he did not touch his luggage.
This incident changed the whole course of his life. He decided to fight all such injustices with the weapon of Truth. Later on, he named this weapon Satyagraha.
More trouble was still in store for him. Next morning, he went to Charlestown by train. He had now to travel by a stage-coach to Johannesburg, but he was not allowed to sit inside the coach with white passengers. To avoid confrontation Gandhiji sat outside on the coach-box behind the coachman. After some time the conductor asked him to sit on a dirty sack on the step below. Gandhiji refused. The conductor began to pull him down and give him blows upon blows. Some of the passengers now came to his rescue and Gandhiji was allowed to sit where he was.
These experiences inspired him to do something to end these sufferings of Indians. He called a meeting of the Indians in Pretoria and told them to form a league. This was his first public speech. It caused a new awakening among Indians.
Gandhiji settled out of court the case for which he had gone to South Africa. This enhanced his reputation. He had helped many to settle their disputes out of court.
After his stay for three years in South Africa, Gandhiji returned to India in 1896. In India, he made speeches about the plight of Indians in South Africa. He then set sail for South Africa, with his wife Kasturbai and two sons. In the meanwhile, the newspaper reports of his speeches in India had reached South Africa in a distorted form. From it, the whites thought that Gandhi had abused them in India, and they were furious.
As soon as Gandhiji landed at the port of Durban, a mob of angry whites threw stones and bricks and rotten eggs at him. They tore off his turban and beat him and kicked him until he was almost unconscious.
At that time, the wife of the Superintendent of Police happened to pass by. She ran to his rescue and opened her parasol to protect him, holding it between him and the crowd. She led Gandhiji to a safe place.
The South African Government wanted to punish the wrong-doers, but Gandhiji refused to file a complaint. This had a very good effect on the whites.
In 1906, the Transvaal Government issued an order that all Indians — men, women and children should register themselves with Government by giving their full finger-prints and get their permits. He who fails to do so, will be fined, imprisoned or deported from the country.
Gandhiji declared: `This is an insult to the Indian community. We must fight this `Black Act' in a non-violent way. The Government might use force, arrest us, send us to jail, and prosecute us, but we must face all this without resistance.' He called this `Satyagraha'.
Indians gathered in large numbers and took an oath in the name of God, not to register themselves. They showed wonderful unity. Hundreds of Indians were arrested, but they didn't put up any defence in courts and went to jail. Gandhiji, too, was imprisoned. At last Government made a compromise with Gandhiji and gave a promise in writing to repeal the Black Act if the Indians registered themselves voluntarily.
All the prisoners were released. Most of the Indians supported Gandhiji, but a few rose against. They accused him of being a coward. A Pathan named Mir Alam was one of them. When Gandhiji set out for registration, Mir Alam hit him with a heavy stick. Gandhiji was knocked down unconscious. When he recovered he found himself in the house of an unknown Englishman. The first thing he did was to inquire about Mir Alam and forgive him saying, `I don't want to prosecute him.' Then he called the registration officer, gave him his finger-prints and got himself duly registered.
Thus Gandhiji fulfilled his part of the agreement at the risk of life, but Government went back from its promise and refused to repeal the Black Act.
The Government of South Africa had imposed a heavy poll-tax on Indians. Gandhiji wanted to get all these injustices removed. So again he started the satyagraha movement. A big bonfire was lit and more than two thousand permits were burnt in it. Those who called Gandhiji a coward now greeted him as a real hero.
Gandhiji and many of his colleagues were imprisoned several times in course of this struggle. Gandhiji gave up his practice as a lawyer and devoted all his time in the service of the great cause that he had taken up. He renounced his European dress and put on the simple clothes of a poor Indian labourer. He walked barefoot. He took only one meal a day.
In jail, Gandhiji did hard labour for nine hours a day cheerfully. He never complained about any hardships. He suffered terrible pain of boils in hands, yet did not budge from the work given him. He was made to carry luggage's, and was taken to court handcuffed.
Meanwhile, the court in South Africa declared all Hindu, Muslim and Parsee marriages illegal and the Government supported the court. Kasturba could not brook this insult of Indian womanhood. She asked Gandhiji to enlist her name as the first woman satyagrahi. Women under her leadership broke the law and courted arrest. Kasturba was also arrested and jailed.

Blood ivory: poachers use poison to slaughter elephants in Africa

Cyanide kills at least 87 elephants in Zimbabwe massacre                                            By Divakarbabu on

Poachers have begun using more subtle techniques to slaughter elephants in Zimbabwe, swapping rifles and machetes for industrial grade poison. Yesterday, a provincial courtconvicted three poachers on charges of using cyanide to kill scores of elephants in Zimbabwe's largest national park, sentencing each to at least 15 years in prison. Earlier this week, authorities confirmed that 87 elephants have been killed by cyanide in Hwange National Park, a total that includes the 41 poisoned animals discovered there earlier this month.
It's not entirely clear how the elephants were poisoned, though authorities believe poachers placed cyanide in areas where the animals are known to graze before seizing their valuable ivory tusks. Fifty-one tusks have been recovered thus far, officials told CNN, meaning that poachers may have escaped with more than 120. Investigations are ongoing, but officials believe the operation likely impacted other animals in the area, as well.
"Several other animals have also died, but we don't have the total number yet," Jerry Gotora, director of the Zimbabwe parks department, told AFP on Tuesday.
"THIS IS SOMETHING OF A FIRST FOR ZIMBABWE."
Elephant and rhinoceros populations have declined at alarming rates over the past few years, due in large part to surging demandfor ivory in China, where the material is used for valuable carvings and traditional elixirs. Rising demand has sent prices skyward — one pound of ivory can fetch $1,300 on the black market — fueling a nefarious network of poachers across Africa. Reports suggest that ivory trade revenue has been used tofund wars and terrorist groups, including al-Shabaab, the Somalia-based militant group believed be behind last week's attack on a mall in Kenya.
The Convention on International Trade in Endangered Species (CITES) passed an international ban on ivory trading in 1989, but enforcing it has proven to be difficult. Experts believe tens of thousands of elephants are killed for their ivory every year, and evidence suggests that the trend is only worsening; in 2011, authorities seized more illegal ivory at ports than at any point since 1989, when record keeping began.

Poachers in Namibia have been known to poison vultures in order to prevent them from circling over an elephant carcass and alerting authorities. There have been reports ofisolated wildlife poisonings in the past — including an incident at Hwange National Park two years ago — but experts say the practice is far from common, and has never been deployed on a scale as large as what happened in Zimbabwe.
"This is something of a first for Zimbabwe, and it may be a first for most elephant-rich countries," says Jimmiel Mandima, director of program design and policy at the African Wildlife Foundation in Washington, DC.
Mandima, a Zimbabwe national, says the country has long been a leader in conservation among African nations, though budget constraints have hampered its efforts to protect its wildlife population. According to AFP, approximately 50 rangers are responsible for Hwange National Park, and authorities say at least 10 times that are needed to patrol the 5,660-square mile area.
"AS LONG AS THE MARKET IS ROBUST FOR IVORY THERE WILL BE CRUEL POACHING OF WILD ELEPHANTS."
"Because economic conditions are not the best, the wildlife authority responsible for overseeing anti-poaching and protection is really running on a tight budget," Mandima said in a phone interview with The Verge. "They are not always able to be on the ground when needed."
Environment Minister Saviour Kasukuwere has vowed to crack down on those responsible for the Hwange massacre, calling for stiffer jail time and penalties for convicted poachers. Earlier this year, the Obama administration pledged $10 million to help combat wildlife poaching in Africa, but experts say more cooperative and forceful action must be taken to fight an ivory market that has shown no signs of slowing down.
"Parties with strong domestic markets — from Zimbabwe to Japan to the United States — should shut these markets down and enact strict domestic legislation prohibiting the commercialization of ivory," Adam Roberts, executive vice president of the animal welfare group Born Free, said in an email to The Verge. "As long as the market is robust for ivory there will be cruel poaching of wild elephants to supply this demand."


prosthetic leg

See the world's first mind-controlled prosthetic leg in action

ric bionic leg
Prosthetic legs have gotten smarter and smarter thanks to advanced sensors and lightweight motors, but this week they're getting their biggest overhaul yet: the latest bionic leg can be controlled entirely by its wearer's mind. Though the mind-controlled prosthetic leg has been in the works for four years now, the research team behind it has only today published the details of its development, which are appearing in a paper in The New England Journal of Medicine.
The work comes out the Rehabilitation Institute of Chicago (RIC), which has a center dedicated to researching bionic medicine. The institute says that the leg can naturally switch between different types of movements simply by having its wearer think about them. "The bionic leg allows me to seamlessly walk up and down stairs and even reposition the prosthetic by thinking about the movement I want to perform," Zac Vawter, who tested the bionic leg, says in a statement. "This is a huge milestone for me and for all leg amputees."
"A MISTAKE OR ERROR ... COULD BE POTENTIALLY CATASTROPHIC."
Though mind-controlled arms are already available, making a mind-controlled leg is an entirely different matter. "If there is a mistake or error that could cause someone to fall, that could be potentially catastrophic," Levi Hargrove, the project's lead researcher, tells NBC News. "We want to avoid that at all costs." But the mind-controlled leg appears to be operating smoothly. Last year, the research team publicized its progress after Vawter, while wearing the leg, climbed the full 103 floors of Chicago's Willis (née Sears) Tower.
The technology works much in the same way that researchers have been able to build bionic arms: Nerves heading toward a patient's damaged muscle are rewired onto healthy muscle, and a sensor is placed nearby to read what the nerves are saying. The bionic leg is then able to take that information and turn it into whatever action that its wearer originally conveyed through thought.
The RIC was given $8 million in funding from the US Army to work on creating the mind-controlled bionic leg. Defense arms of the US government have been interested in advancing prosthetics for some time now, particularly as a way to help injured veterans, and this isn't the only defense-funded project at the RIC. The RIC has also received funding from DARPA for improving the overall speed of neural interfaces — something that should help the RIC's bionic leg, as well as DARPA's own mind-controlled bionic arm.
The RIC hopes to have its bionic legs available for anyone to test within the next five years. Of course, cost may be a big issue, but Hargrove says that they're doing their best to keep the price down. "We are leveraging developments in related industries to make sure we use low-cost components whenever possible," he tells NBC News, which notes that bionic arms can run anywhere from $20,000 to $120,000.
"IT MAKES A PHENOMENAL DIFFERENCE."
For now, Vawter is the only person wearing one the RIC's mind-controlled bionic legs. But if the leg works as well as he says it does, it should be a marked improvement over existing technology once it leaves the lab. He tells NBC News, "It makes a phenomenal difference.

carbon nanotube electronics

Stanford scientists create world's first carbon nanotube computer

Computers of the future could be even smaller, faster, and more efficient — all by doing away with the very material that currently comprises their core.
In a finding that builds on earlier work from several institutions, including IBM, a team of electrical engineers at Stanford University today announced the creation of the first-ever computer based on carbon nanotubes. The nanotubes are used to create a novel kind of transistor, one that doesn't rely on conventional silicon. "This is the most complex electronic ever built with carbon nanotubes," said Max Shulaker, a co-author on the paper announcing the progress, which is published in Nature. "There's been a lot of hype around this field, but people weren't actually sure if you could use them in a practical way like this."
ENHANCED SPEED AND ENERGY EFFICIENCY
Carbon nanotubes, or CNTs, are infinitesimally small cylinders made from sheets of carbon atoms. When arrayed into transistors, the nanotubes are small enough that engineers can fit many more of them onto a single chip compared to silicon transistors. Their size, combined with other properties of the nanotubes — including high conductivity and rapid on-off ability — would mean enhanced speed and energy efficiency. That's particularly important given the inherent limits of silicon-based transistors: researchers have been doubling the number of transistors on a chip approximately every two years (a process known as Moore's Law) but that progress will within decades reach an end.
"WHEN ONE CHIP HAS BILLIONS OF TRANSISTORS, THAT 2 PERCENT BECOMES A BIG PROBLEM."
The computer that Shulaker and his colleagues build is extremely basic: it contains only 178 transistors, and runs a rudimentary operating system that allows for the completion of counting and number sorting tasks (as well as the ability to toggle between the two). Still, getting to this point has been years in the making — and required that researchers overcome two daunting challenges. Carbon nanotubes tend to self-assemble unpredictably, and that assembly process also yields some nanotubes with metallic properties, which will cause a transistor to short-circuit. "We had to do a lot of work to get these nanotubes to align how we wanted, and to be perfectly reliable," Shulaker said. "Even 98 percent isn't good enough; when one chip has billions of transistors, that 2 percent becomes a big problem."
To overcome those challenges, the Stanford team used what they've dubbed as "an imperfection-immune design." The approach essentially uses electricity to vaporize metallic nanotubes during the fabrication process, and relies on an algorithm to create circuit designs that function despite any misalignment of the nanotubes. According to Shulaker, the methods can be scaled to support industrial manufacturing of carbon nanotube transistors in the future. "You can't expect to make these transistors one-by-one," he said. "I think what this shows is that we can actually start to compete with silicon."
"MAYBE ONE DAY, SILICON VALLEY WILL BECOME CARBON VALLEY."
Despite the exciting progress, Shulaker is also realistic about the prospects of electronics running on carbon nanotubes anytime soon. Additional research will be necessary to yield more sophisticated CNT-based computers, and the nanotubes are only one of several emerging technologies with the potential to replace silicon. Not to mention that any major disruption to the silicon-based electronics industry would be a formidable challenge. "I'd be naive to think that one fine morning, the industry will just wake up and toss silicon out the window," he said. "But I like to think that, maybe one day, Silicon Valley will become Carbon Valley."

First 360-Degree Panorama From NASA's Curiosity Mars Rover

First 360-Degree Panorama From NASA's Curiosity Mars Rover

PASADENA, Calif. -- Remarkable image sets from NASA's Curiosity rover and Mars Reconnaissance Orbiter are continuing to develop the story of Curiosity's landing and first days on Mars.
The images from Curiosity's just-activated navigation cameras, or Navcams, include the rover's first self-portrait, looking down at its deck from above. Another Navcam image set, in lower-resolution thumbnails, is the first 360-degree view of Curiosity's new home in Gale Crater. Also downlinked were two, higher-resolution Navcams providing the most detailed depiction to date of the surface adjacent to the rover.
"These Navcam images indicate that our powered descent stage did more than give us a great ride, it gave our science team an amazing freebie," said John Grotzinger, project scientist for the mission from the California Institute of Technology in Pasadena. "The thrust from the rockets actually dug a one-and-a-half-foot-long [0.5-meter] trench in the surface. It appears we can see Martian bedrock on the bottom. Its depth below the surface is valuable data we can use going forward."
Another image set, courtesy of the Context Camera, or CTX, aboard NASA's Mars Reconnaissance Orbiter has pinpointed the final resting spots of the six, 55-pound (25-kilogram) entry ballast masses. The tungsten masses impacted the Martian surface at a high speed of about 7.5 miles (12 kilometers) from Curiosity's landing location.
Curiosity's latest images are available at: http://1.usa.gov/MfiyD0 .
Wednesday, the team deployed the 3.6 foot-tall (1.1-meter) camera mast, activated and gathered surface radiation data from the rover's Radiation Assessment Detector and concluded testing of the rover's high-gain antenna.
Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on NASA's Mars rovers Spirit and Opportunity. Some of the tools, such as a laser-firing instrument for checking rocks' elemental composition from a distance, are the first of their kind on Mars. Curiosity will use a drill and scoop, which are located at the end of its robotic arm, to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into the rover's analytical laboratory instruments.
To handle this science toolkit, Curiosity is twice as long and five times as heavy as Spirit or Opportunity. The Gale Crater landing site places the rover within driving distance of layers of the crater's interior mountain. Observations from orbit have identified clay and sulfate minerals in the lower layers, indicating a wet history.
The Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE) camera is operated by the University of Arizona in Tucson. The instrument was built by Ball Aerospace & Technologies Corp. in Boulder, Colo. The Mars Reconnaissance Orbiter and Mars Exploration Rover projects are managed by JPL for NASA's Science Mission Directorate, Washington. The rover was designed, developed and assembled at JPL. JPL is a division of the California Institute of Technology in Pasadena. Lockheed Martin Space Systems in Denver built the orbiter.
