Audi R8 Spyder.......for naren

Audi R8 Spyder is open-top two-seater supercar. 2011 model  will be available both with V-10 and V-8 power.

Audi R8 Spyder is powered by a 5.2-litre V10 engine, large parts of which are built by hand. It has 518bhp that’s generated at 8,000rpm and 530Nm of torque at 6,500rpm. Get medieval with the throttle and the 0-62mph time is 4.1s, then the car will pass 124mph in just 12.7s on its way to a screaming 194mph maximum. Power is sent to the road through a six-speed manual gearbox and Audi famous quattro four-wheel-drive system which has a heavy bias towards the rear wheels in the R8. There’s also the option of an R Tronic automated manual gearbox with paddle shifters.

the Spyder is just fractionally slower than its hardtop sibling (which is lighter by 220 pounds). Audi also claims that the power soft top is good all the way to the Spyder’s 194-mph top speed. The Spyder not only loses the fixed roof but also the optional sideblades of the coupe. The car’s top-up profile borrows a bit from the BMW 6-series convertible, with an upright, glass rear window (which can be powered up and down) tucked between the trailing edges of the top, which extend rearward. Another idea borrowed from BMW droptops is the use of special heat-reflective seat upholstery, in this case Nappa leather. The R8 Spyder does offer an entirely unique new feature, too, one that’s perfectly suited to the cell-phone age: a series of microphones attached to the shoulder belts (with one more inthe dash), to facilitate hands-free calls even during high-speed, top-down driving. The R8 Spyder goes on sale in Europe this spring but won’t reach North America until summer 2010. When it arrives, as a 2011 model, it will be available both with V-10 and V-8 power.

Integral to the way the R8 drives is its mid-mounted engine which enables a 43:57 weight distribution. The suspension system is a double wishbone set-up on all four wheels and Audi’s magnetic ride dampers are standard. These can adjust their settings automatically according to the driver’s style. They can be set into one of two modes for a more comfortable experience or a more dynamic one.

Indian freedom fighter Bhagat Singh, at the age of 21 in jail

Bhagat Singh

Bhagat Singh was one of the most prominent faces of Indian freedom struggle. He was a revolutionary ahead of his times. By Revolution he meant that the present order of things, which is based on manifest injustice must change. Bhagat Singh studied the European revolutionary movement and was greatly attracted towards socialism. He realised that the overthrow of British rule should be accompanied by the socialist reconstruction of Indian society and for this political power must be seized by the workers

Though portrayed as a terrorist by the British, Sardar Bhagat Singh was critical of the individual terrorism which was prevalent among the revolutionary youth of his time and called for mass mobilization. Bhagat Singh gave a new direction to the revolutionary movement in India. He differed from his predecessors on two counts. Firstly, he accepted the logic of atheism and publicly proclaimed it. Secondly, until then revolutionaries had no conception of post-independence society. Their immediate goal was destruction of the British Empire and they had no inclination to work out a political alternative. Bhagat Singh, because of his interest in studying and his keen sense of history gave revolutionary movement a goal beyond the elimination of the British. A clarity of vision and determination of purpose distinguished Bhagat Singh from other leaders of the National Movement. He emerged as the only alternative to Gandhi and the Indian National Congress, especially for the youth.Bhagat Singh was born in a Sikh family in village Banga in Layalpur district of Punjab (now in Pakistan). He was the third son of Sardar Kishan Singh and Vidyavati. Bhagat Singh's family was actively involved in freedom struggle. His father Kishan Singh and uncle Ajit Singh were members of Ghadr Party founded in the U.S to oust British rule from India. Family atmosphere had a great effect on the mind of young Bhagat Singh and patriotism flowed in his veins from childhood.

While studying at the local D.A.V. School in Lahore, in 1916, young Bhagat Singh came into contact with some well-known political leaders like Lala Lajpat Rai and Ras Bihari Bose. Punjab was politically very charged in those days. In 1919, when Jalianwala Bagh massacre took place, Bhagat Singh was only 12 years old. The massacre deeply disturbed him. On the next day of massacre Bhagat Singh went to Jalianwala Bagh and collected soil from the spot and kept it as a memento for the rest of his life. The massacre strengthened his resolve to drive British out from India.

In response to Mahatma Gandhi's call for non-cooperation against British rule in 1921, Bhagat Singh left his school and actively participated in the movement. In 1922, when Mahatma Gandhi suspended Non-cooperation movement against violence at Chauri-chaura in Gorakhpur, Bhagat was greatly disappointed. His faith in non violence weakened and he came to the conclusion that armed revolution was the only practical way of winning freedom. To continue his studies, Bhagat Singh joined the National College in Lahore, founded by Lala Lajpat Rai. At this college, which was a centre of revolutionary activities, he came into contact with revolutionaries such as Bhagwati Charan, Sukhdev and others.he

He went to Lahore and formed a union of revolutionaries by name 'Naujavan Bharat Sabha'. He started spreading the message of revolution in Punjab. In 1928 he attended a meeting of revolutionaries in Delhi and came into contact with Chandrasekhar Azad. The two formed 'Hindustan Samajvadi Prajatantra Sangha'. Its aim was to establish a republic in India by means of an armed revolution.

In February 1928, a committee from England, called Simon Commission visited India. The purpose of its visit was to decide how much freedom and responsibility could be given to the people of India. But there was no Indian on the committee. This angered Indians and they decided to boycott Simon Commission. While protesting against Simon Commission in Lahore, Lala Lajpat Rai was brutally Lathicharged and later on succumbed to injuries. Bhagat Singh was determined to avenge Lajpat Rai's death by shooting the British official responsible for the killing, Deputy Inspector General Scott. He shot down Assistant Superintendent Saunders instead, mistaking him for Scott. Bhagat Singh had to flee from Lahore to escape death punishment.

Instead of finding the root cause of discontent of Indians, the British government took to more repressive measures. Under the Defense of India Act, it gave more power to the police to arrest persons to stop processions with suspicious movements and actions. The Act brought in the Central Legislative Assembly was defeated by one vote. Even then it was to be passed in the form of an ordinance in the "interest of the public." Bhagat Singh who was in hiding all this while, volunteered to throw a bomb in the Central Legislative Assembly where the meeting to pass the ordinance was being held. It was a carefully laid out plot, not to cause death or injury but to draw the attention of the government, that the modes of its suppression could no more be tolerated. It was decided that Bhagat Singh and Batukeshwar Dutt would court arrest after throwing the bomb.

On April 8, 1929 Bhagat Singh and Batukeshwar Dutt threw bombs in the Central Assembly Hall while the Assembly was in session. The bombs did not hurt anyone. After throwing the bombs, Bhagat Singh and Batukeshwar Dutt, deliberately courted arrest by refusing to run away from the scene. During his trial, Bhagat Singh refused to employ any defence counsel. In jail, he went on hunger strike to protest the inhuman treatment of fellow-political prisoners by jail authorities. On October 7, 1930 Bhagat Singh, Sukh Dev and Raj Guru were awarded death sentence by a special tribunal. Despite great popular pressure and numerous appeals by political leaders of India, Bhagat Singh and his associates were hanged in the early hours of March 23, 1931.

Black Mamba Snake .....it for black mamba lovers specially for naren

Black Mamba Snake

Black mambas are one of Africa''s most dangerous and feared snakes. Nothing is truer when you are standing in front of big black mamba hissing loudly, mouth gaping, striking rapidly in your direction. But are all the frightening stories about black mambas true? I don''t think so
Black mambas are one of Africa''s most dangerous and feared snakes. Nothing is truer when you are standing in front of big black mamba hissing loudly, mouth gaping, striking rapidly in your direction. But are all the frightening stories about black mambas true? I don''t think so. On the African continent many myths are told about these wonderful creatures. Stories abound about black mambas chasing people for miles, attacking when they notice you and visiting houses to kill every single person inside. All are exaggerations.


Black mambas live in the savannas and rocky hills of southern and eastern Africa. They are Africa''s longest venomous snake, reaching up to 14 feet (4.5 meters) in length, although 8.2 feet (2.5 meters) is more the average. They are also among the fastest snakes in the world, slithering at speeds of up to 12.5 miles per hour (20 kilometers per hour).

A black mamba family was observed on the banks of the Limpopo River. There were three mambas, each about 2,5 meters long, occupying a heap of large creeper-covered boulders near a river bank. Sugar birds would hover near the creeper, virtually motionless despite their whirring wings as they gathered nectar, pursuing one another in swift, darting flight, seemingly unaware of the snakes.


Black Mamba Snake Description

Adult Black mamba snakes have an average length of 2.5 metres (8.2 feet) and a maximum length of 4.5 metres (14 feet). The Black mamba snake receives it''s name from the black colouration inside of it''s mouth, rather than their skin colour which is a grey to olive tone. The Black mamba snake is the fastest moving snake in the world, capable of moving up to 20 km/h (12.5 mph). However it uses this speed to evade danger, rather than catch prey.

Behavior

A single bite from a Black Mamba may inject enough venom to kill 20-40 grown men, easily killing one unless the appropriate anti-venom is administered in time. When cornered, they will readily attack. When in the striking position, the mamba flattens its neck, hisses very loudly and displays its inky black mouth and deadly fangs.

Habitat

Black mambas can be found generally in Eastern Africa, from southern Ethiopia to southwest Africa. They prefer the open areas and will settle in spots such as savannahs, rocky areas and open woodlands. They will settle down in the same spot nightly and tend to be diurnal or day hunters. They like to occupy empty termite mounds, rocky crevices, burrows and hollow trees.

Breeding

This takes place in spring and early summer. Males may travel long distances looking for females. After mating, the snakes return to their own holes. Females lay between 10 and 25 eggs, usually in decaying vegetation. The decomposition of the vegetation gives off heat, which helps to warm the eggs and speed up hatching time. The shells of the eggs allow water and oxygen to reach the developing embryos.

Thomas Alva Edison

                  Thomas Alva Edison

               Edison was born in Milan, Ohio, on February 11, 1847. He attended school for only three months, in Port Huron, Michigan. When he was 12 years old he began selling newspapers on the Grand Trunk Railway, devoting his spare time mainly to experimentation with printing presses and with electrical and mechanical apparatus. In 1862 he published a weekly, known as the Grand Trunk Herald, printing it in a freight car that also served as his laboratory. For saving the life of a station official’s child, he was rewarded by being taught telegraphy. While working as a telegraph operator, he made his first important invention, a telegraphic repeating instrument that enabled messages to be transmitted automatically over a second line without the presence of an operator.


              Edison next secured employment in Boston and devoted all his spare time there to research. He invented a vote recorder that, although possessing many merits, was not sufficiently practical to warrant its adoption. He also devised and partly completed a stock-quotation printer. Later, while employed by the Gold and Stock Telegraph Company of New York City he greatly improved their apparatus and service. By the sale of telegraphic appliances, Edison earned $40,000, and with this money he established his own laboratory in 1876. Afterward he devised an automatic telegraph system that made possible a greater speed and range of transmission. Edison’s crowning achievement in telegraphy was his invention of machines that made possible simultaneous transmission of several messages on one line and thus greatly increased the usefulness of existing telegraph lines. Important in the development of the telephone, which had recently been invented by the American physicist and inventor Alexander Graham Bell, was Edison’s invention of the carbon telephone transmitter.



            In 1877 Edison announced his invention of a phonograph by which sound could be recorded mechanically on a tinfoil cylinder. Two years later he exhibited publicly his incandescent electric light bulb, his most important invention and the one requiring the most careful research and experimentation to perfect. This new light was a remarkable success; Edison promptly occupied himself with the improvement of the bulbs and of the dynamos for generating the necessary electric current. In 1882 he developed and installed the world’s first large central electric-power station, located in New York City. His use of direct current, however, later lost out to the alternating-current system developed by the American inventors Nikola Tesla and George Westinghouse.




          In 1887 Edison moved his laboratory from Menlo Park, New Jersey, to West Orange, New Jersey, where he constructed a large laboratory for experimentation and research. (His home and laboratory were established as the Edison National Historic Site in 1955). In 1888 he invented the kinetoscope, the first machine to produce motion pictures by a rapid succession of individual views. Among his later noteworthy inventions was the Edison storage battery (an alkaline, nickel-iron storage battery), the result of many thousands of experiments. The battery was extremely rugged and had a high electrical capacity per unit of weight. He also developed a phonograph in which the sound was impressed on a disk instead of a cylinder. This phonograph had a diamond needle and other improved features. By synchronizing his phonograph and kinetoscope, he produced, in 1913, the first talking moving pictures. His other discoveries include the electric pen, the mimeograph, the microtasimeter (used for the detection of minute changes in temperature), and a wireless telegraphic method for communicating with moving trains.


           At the outbreak of World War I, Edison designed, built, and operated plants for the manufacture of benzene, carbolic acid, and aniline derivatives. In 1915 he was appointed president of the U.S. Navy Consulting Board and in that capacity made many valuable discoveries. His later work consisted mainly of improving and perfecting previous inventions. Altogether, Edison patented more than 1000 inventions. He was a technologist rather than a scientist, adding little to original scientific knowledge. In 1883, however, he did observe the flow of electrons from a heated filament—the so-called Edison effect—whose profound implications for modern electronics were not understood until several years later. Edison died in West Orange on October 18, 1931.
