FARTHEST DISTANCE TRAVELLED ON A ZIP WIRE USING HAIR

Sailendra Nath Roy was an Indian man from Siliguri, West Bengal, who registered his name in the Guinness Book of World Records for the farthest distance travelled on a zip wire using hair. He created the record at Neemrana Fort Palace, Neemrana, Rajasthan, India, on 1 March 2011. Sailendra zip lined the entire 82.5 m attached to the zip wire only by his hair, which he tied in a looped ponytail. Again in September 2012 he pulled a Darjeeling Himalayan Railway locomotive with his ponytail in north Bengal for 2.5 metres (8.2 feet) in the town of Siliguri, West Bengal. He worked as a home guard under West Bengal Police.

Death
Roy died on 28 April 2013, while trying to beat his own record of farthest distance travelled on a zip wire using hair. Roy died due to heart failure during his record try at Teesta River. After completing about 40 per cent of the distance, which started from a point close to the Sevak Coronation Bridge, he got stuck on the wire and was unable to move. He was left hanging in midair for about 25 minutes. He died while struggling to free himself as helpless spectators looked on. He was 49 years old.

WORLD'S LARGEST SUNDIAL

The Jantar Mantar, situated at Jaipur, Indua is the world's largest sundial. It is a collection of architectural astronomical instruments, built by Sawai Jai Singh who was a Mughal Commander and served Emperor Aurangzeb and later Mughals. He had constructed a total of five such facilities at different locations, including the ones at Delhi and Jaipur. The Jaipur observatory is the largest and best preserved of these. It has been inscribed on the World Heritage List as "an expression of the astronomical skills and cosmological concepts of the court of a scholarly prince at the end of the Mughal period". Early restoration work was undertaken under the supervision of Major Arthur Garrett, a keen amateur astronomer, during his appointment as Assistant State Engineer for the Jaipur District.

The name is derived from jantar("instrument/machine"), and Mantar ("formula", or in this context "calculation"). Therefore jantar mantar means literally 'calculation instrument'. This observatory has religious significance, since ancient Indian astronomers were also Jyotisa masters.

The observatory consists of fourteen major geometric devices for measuring time, predicting eclipses, tracking stars' location as the earth orbits around the sun, ascertaining the declinations of planets, and determining the celestial altitudes and related ephemerides. Each is a fixed and 'focused' tool. The Samrat Yantra, the largest instrument, is 90 feet (27 m) high, its shadow carefully plotted to tell the time of day. Its face is angled at 27 degrees, the latitude of Jaipur. The Hindu chhatri (small cupola) on top is used as a platform for announcing eclipses and the arrival of monsoons.

Built from local stone and marble, each instrument carries an astronomical scale, generally marked on the marble inner lining. Bronze tablets, all extraordinarily accurate, were also employed. Thoroughly restored in 1901, the Jantar Mantar was declared a national monument in 1948.

The instruments are in most cases huge structures. The scale to which they have been built has been alleged to increase their accuracy. However, the penumbra of the sun can be as wide as 30 mm, making the 1mm increments of the Samrat Yantra sundial devoid of any practical significance. Additionally, the masons constructing the instruments had insufficient experience with construction of this scale, and subsidence of the foundations has subsequently misaligned them. The samrat yantra, for instance, which is a sundial, can be used to tell the time to an accuracy of about two seconds in Jaipur local time.[3] The Giant Sundial, known as the Samrat Yantra (The Supreme Instrument) is the world's largest sundial, standing 27 meters tall. Its shadow moves visibly at 1 mm per second, or roughly a hand's breadth (6 cm) every minute, which can be a profound experience.

Today the observatory is a popular tourist attraction. However, local astronomers still use it to predict the weather for farmers, although their authority is becoming increasingly questionable. Students of astronomy and Vedic astrology are required to take some of their lessons at the observatory, and it can be said that the observatory is the single most representative work of Vedic thought that still survives, apart from the texts. Many of the smaller instruments display remarkable innovation in architectural design and its relation to function, for instance - the Ram Yantra.

WORLD'S LARGEST HUMAN GATHERING

An estimated 30 million people visited the Maha Kumbh Mela on 10 February 2013 and an estimated 100 million are expected to visit the place during the festival spread over 55 days. Both (in a single day and over a specific period) are the largest peaceful human assemblies in the world. According to estimates, around 70 million people participated in the 45-day Ardh Kumbh Mela at Prayag in 2007. The Purna Kumbh Mela held in 2001 in Prayag was estimated to have attracted between 30 and 70 million people.

The Maha Kumbh Mela, or Grand Pitcher Festival, takes place every 12 years in Northern India and sees millions of devotees bathe in the Ganges to purify their sins. The Kumbh is held at the confluence of the Ganges and Yamuna rivers, where Hindu scriptures say the gods spilt a drop of the elixir of immortality.

Kumbh Mela takes place every twelve years at one of four places: Allahabad, Haridwar, Ujjain and Nashik. The Mela in its different forms alternates between Prayag, Nashik, Ujjain and Haridwar every third year. The Ardh (half) Kumbh Mela is celebrated every six years at only two places, Haridwar and Prayag.

    Kumbha Mela: Held at all four places.
    Ardha Kumbha Mela: Held at Haridwar and Prayag, every 6 years.
    Purna Kumbha Mela: Held only at Prayag every 12 years.
    Maha Kumbha Mela: Held only at Prayag, every 144 years.

WORLD'S FASTEST FISH

The fastest swimming fish on earth are the sailfish, reaching speeds of up to 110 km/h (68 mph), which is the highest speed reliably reported in a fish. Sailfish are two species of fishes in the genus Istiophorus, living in warmer sections of all the oceans of the world, including the seas of India. They are blue to gray in color and have a characteristic sail (dorsal fin) which often stretches the entire length of the back. Another notable characteristic is the elongated bill, resembling that of the swordfish and marlins.

The two species are:
* Atlantic sailfish (Istiophorus albicans).
* Indo-Pacific sailfish (Istiophorus platypterus).
Both species of sailfishes feed on the surface or at mid-depths on smaller pelagic fishes and squid. Generally, sailfish grow to a size of more than 3 m (10 ft) in length and rarely weigh over 90 kg (200 lb).

The sail is normally kept folded down and to the side when swimming, but it may be raised when the sailfish feels threatened or excited, making the fish appear much larger than it actually is. This tactic has also been observed during feeding, when a group of sailfish use their sails to "herd" a school of fish or squid.

Sailfish are highly prized game fish and are known for their incredible jumps.

The Indo-Pacific sailfish, Istiophorus platypterus, is a sailfish native to the Indian and Pacific Oceans. It is dark blue on top, brown-blue laterally, silvery white underbelly; upper jaw elongated in form of spear; first dorsal fin greatly enlarged in the form of a sail, with many black spots, its front squared off, highest at its midpoint; pelvic fins very narrow, reaching almost to the anus; body covered with embedded scales, blunt at end; lateral line curved above pectoral fin, then straight to base of tail.they have a large and sharp bill, that they use for hunting. They feed on tuna and mackerel, some of the fastest fish in the Ocean. They are able to prey on the faster fish in the sea because of their faster speed.

WORLD'S LARGEST CANNON

The Jaivana cannon is the world's biggest wheeled cannon ever made. It is located at the Jaigarh Fort, Jaipur. It was cast in 1720, during the reign of Maharaja Sawai Jai Singh II of Jaipur. Jaivan rests on a high 4 wheeled carriage. The front wheels are 2.74 m in diameter and the rear wheels are 1.37 m in diameter. The barrel is 6.147 m (20 feet 2 inches) long and weighs 50 tons. It rests on a 7.3 m long shaft. The tip of the barrel is 711 mm in dia., while the rear of the barrel is 906 mm dia. An 776 mm long elevating screw was used for raising and lowering the barrel. The barrel has floral design. An elephant rests on the tip of the barrel and a pair of peacocks are carved in the centre. A pair of ducks also decorates the rear of the barrel. Reportedly, it took four elephants to swivel it around on its axis. About 100 kg. (a quintal) of gun powder fired a shot ball weighing 50 kg.

Never used in battle, the Maharaja Jai Singh reportedly test-fired it once in 1720. The cannon ball is said to have landed at Chaksu about 40 km to the south. The impact formed a pond at the spot. Cannons always had a water tank beside them, for the gunner to jump into to avoid the massive shock wave. Jaivan's gunner is said to have died on the spot on firing the cannon, before he could jump into water. Eight people and one elephant were also reportedly killed by the shock wave and many houses collapsed in Jaipur.The two thick rings on the barrel were used for lifting it with the help of a crane which, though incomplete, is still lying in Jaigarh.

Jaigarh Fort was a center of artillery production for the Rajputs. The foundries provide fascinating information for the visitors. The manner in which they drew in blasts of air from the desert is most intriguing. The formidable strength of Jaivan's builder, the scientifically inclined warrior Sawai Jai Singh II, lay in the large number of artillery and copious supply of munitions which he maintained.

WORLD'S HIGHEST MOTORABLE ROAD

Khardung La (elevation 5602 m or 18 380 ft)in India’s Ladakh, in the state of Jammu & Kashmir is known as the world’s highest motorable mountain pass.

The pass on the Ladakh Range lies north of Leh and is the gateway to the Shyok and Nubra valleys. The Siachen Glacier lies partway up the latter valley. Built in 1976, it was opened to motor vehicles in 1988 and has since seen many automobile, motorbike and mountain biking expeditions. Maintained by the Border Roads Organisation, the pass is strategically important to India as it is used to carry essential supplies to the Siachen. Khardong La is historically important as it lies on the major caravan route from Leh to Kashgar in Chinese Central Asia. About 10,000 horses and camels used to take the route annually, and a small population of Bactrian camels can still be seen at Hundar, in the area north of the pass, mute witnesses to history. The camels can be hired for ride by tourists.

Khardung La is situated 37 km by road from Leh. The first 24 km, as far as the South Pullu check point, are paved. From there to the North Pullu check point about 15 km beyond the pass the roadway is primarily loose rock, dirt, and occasional rivulets of snow melt. However, this pass is in better repair than many of the surrounding passes (Tanglang La, for example). From North Pullu into the Nubra Valley, the road is very well maintained (except in a very few places where washouts or falling rock occur). Hired vehicles (2 and 4-wheel-drive), heavy trucks, and motorcycles regularly travel into the Nubra Valley, though special permits may need to be arranged for travellers to make the journey.
