Bank Clerk Becomes First From Haryana To Summit Mount Kanchenjunga
Last Updated: Sunil Kumar Rohilla from Haryana summited Kanchenjunga, becoming the first from his state to conquer five peaks above 8,000 metres. In a feat that elevated the spirit of an entire state, Sunil Kumar Rohilla from Haryana has carved his name into mountaineering history by summiting Kanchenjunga, the third-highest peak in the world and the highest in the country. Rohilla, a modest bank clerk in Rasulpur village in Karnal, climbed the 8,586 metre-high mountain, becoming the first mountaineer from his state to conquer five peaks above 8,000 metres. Not only did he reach the summit's peak but also unfurled the tricolour upon reaching it. 'This was a dream I've seen for years," said Rohilla, upon returning home on June 25 last year after a gruelling two-month expedition. His journey began on April 22, and it marked more than just a physical challenge, it was a test of mental endurance, willpower, and his lifelong commitment to mountaineering. The climb was far from easy. 'Kanchenjunga is extremely difficult," he explained. The terrain is treacherous and the oxygen levels are dangerously low. Weather can change without warning. I attempted it last year but had to turn back due to severe conditions, he said. This time, with the support of the Indian Army and an international expedition team, and aided by more favourable weather, he triumphed. Rohilla began his mountaineering journey in 2015. Over the past nine years, he has relentlessly scaled some of the most dangerous peaks in the world, including Mount Everest (8,848 metres), Mount Lhotse (8,516 metres), and Mount Manaslu (8,163 metres). Just a month before his Kanchenjunga success, he summited Annapurna I (8,091 metres), often cited as one of the deadliest peaks due to its fatal weather patterns and avalanche risks. With five 8000ers now under his belt, Rohilla is not stopping anytime soon. He has already set his sights on two more of Nepal's giants: Mount Makalu (8,485 metres), the fifth-highest mountain on Earth, and Mount Dhaulagiri (8,167 metres), ranked seventh. His journey from the flatlands of Haryana to the icy heights of the Himalayas is not just a personal victory but a beacon of hope and inspiration. 'He has shown us what passion and perseverance can do," said Ravi Kumar, a close friend. To rise from a small village and stand atop the world's tallest peaks is no small feat. Sunil has become a symbol of what rural people can aspire to, Kumar added. First Published: May 28, 2025, 16:30 IST

The best way to make a huge splash in the pool (it's very hard to do)
Now, scientists at the Georgia Institute of Technology have worked out the mechanics of exactly what these divers are doing to create their massive splashes - and it's a far cry from the simplicity of a belly buster. "It's very difficult to master, it can be quite dangerous, and it requires millisecond control," said Pankaj Rohilla, a postdoctoral researcher and co-author on the paper "Mastering the Manu--how humans create large splashes," published on May 19. The Georgia Tech team of fluid dynamics and biomechanics experts spent months working on the problem. Learning the mechanics involved analyzing more than 75 videos of people doing manu jumps, then taking lab members to Georgia Tech's pool to do more than 50 trial jumps, all filmed in high definition to capture exactly what their bodies were doing at each millisecond. Finally, researcher and co-author Daehyun Choi built a "Manubot," a hand-sized robot that could mimic a diver's body movements during a manu jump to test what exact angle was best to create the biggest possible movement of water. Making the biggest splash possible What Maori jumpers have perfected turns out to involve specific movements all done within as little as 0.14 seconds of each other -- and the exact opposite of the techniques taught to traditional divers, as seen every four years during the Olympics. "It's all about making a V-shape with your body during water entry and then a specific set of underwater body dynamics," said Rohilla. Specifically, the best manu jumpers form a perfect 45-degree V with their bodies in the air. Then, as soon as they touch the water's surface, the diver rolls back and kicks to straighten their body out. This expands the air cavity created when their body enters the water. The height of the splash corresponds to the size of that cavity. The time of cavity collapse is known as the "pinch-off time." Gravitational forces push the water back in the vertical direction, generating an upward jet of water. "It's basically about how much energy you're trapping underwater," said Rohilla. Technically, the initial splash created by the diver's body entering the water is called the crown splash, while the second, caused by the collapsing air cavity, is called a Worthington jet. It requires extreme body control and split-second timing. The V-shape of the body has to be a 45-degree angle to create the fastest and highest Worthington jet, while ensuring the diver's safety. The roll back and kick motion must occur within 0.14 to 0.15 seconds of entering the water when the diver is jumping from 3 meters, said Rohilla. That's about 10 feet high. The higher the jump, the shorter the time the diver has to perform the roll back and kick. "It looks easy but it's actually very challenging," he said. Manu diving can hurt The researchers caution that the manu maneuver is not only difficult but can be risky and painful. "The higher you jump, the less reaction time you have. So it can be quite dangerous," said Rohilla. Especially if you miss the landing shape of 45 degrees, the water can slap the diver's back with a lot of force. "That hurt a few of our teammates. It was very painful," Rohilla said. "You could even hurt your spine, so it can be a risky sport." Manu diving has been banned in some pools in New Zealand, including one area where a child was injured. A Maori cultural sport The sport back at least several decades and has become an important cultural tradition in New Zealand. The name most likely comes from the Maori word "manu" which means bird, though some suggest it's a shortened form of Mangere, a suburb of Auckland where the sport is popular. It's gone from something people did for fun to showing off their prowess as a competitive sport. In 2024, the first Manu World Championships were held in New Zealand's capital, Wellington. Other competitions appeared to have been held dating back to at least 2011. In Wellington this year, more than $23,000 in prize money is on the line. Jump heights range from three feet above the water for children to as high as 16 feet for adults. Divers can compete in the traditional manu style of the V-Bomb, but new styles have also been introduced, including The Gorilla, the Cannonball, and The Coffin. The competition uses high-tech cameras to calculate the splash height of each diver to ensure fair scoring. 'Thousands and thousands of hours of practice' The fun of manu diving is making a huge splash, something people love given the quantity of splashes observed wherever children play in pools. It's also the exact opposite of the clean, minimal splash demanded in competitive diving, where scoring depends, in part, on producing the smallest possible splash as the diver plunges into the water. "We call it 'ripping,'" said Phil Tonne, a dive coach at the University of California, Davis. "The least amount of splash correlates to the highest scores." Making no splash is as hard as making a big splash. "You want to be as streamlined as you can possibly get," Tonne said. "It takes thousands and thousands of hours of practice."

Scientists report the best way to make a huge splash when jumping in a pool
Scientists report the best way to make a huge splash when jumping in a pool A unique and fiendishly difficult type of diving has been perfected by the Māori of New Zealand. It can shoot out 32-foot water jets. Show Caption Hide Caption At US Olympic diving trials, Olympians will pass down their rings When a diver qualifies for the Paris Games at the U.S. diving trials, former Olympians will pass down a token to the next generation. Sure, there's the bellyflop. The cannonball. The bomb. But for the biggest pool splash of all, nothing beats "popping a Manu," a unique and fiendishly difficult type of diving perfected by the Māori of New Zealand that can shoot up 32-foot water jets. The decades-old cultural tradition is so popular that there's an annual world championship held in Auckland with cash prizes, the most recent of several such events over the past two decades.

Royal club forced to let ‘cheating' golfer back on fairway
A royal golf club that kicked out a member accused of cheating has been forced to let her back on the fairway. Rina Rohilla had her membership at the Royal Mid-Surrey Golf Club, where King Edward VIII was once captain, terminated after being accused of fiddling her scores in September 2019. She sued, claiming she was unfairly booted out because she was unpopular with some members of a 'core clique' at the club. Ms Rohilla said 'chief amongst them' was the vice-captain Beverley Mayes, with complaints made in an email about her 'gamesmanship, the terrible way in which she treats her opponents' and comments that 'her traits/mannerisms/conduct are certainly not as we would want from a member'. She has now won her legal fight to force the club to take her back after a judge ruled in her favour. Giving judgment, Judge Andrew Holmes said there was a 'clear dislike' for Ms Rohilla among some at the club. He said some 'minds were made up' about her guilt soon after she was accused and that there had been 'clear bias' against her, with a 'clear desire to secure her expulsion.' 'I found Ms Rohilla to be an honest witness and I found no basis upon which I could have concluded that she was lying to me when she denied that she had changed the scores.' Central London County Court heard Ms Rohilla, an insolvency practitioner, had joined the club in 2003 and was devoted to golf. But her expulsion from the club stemmed from her participation in the Harare 125 Bowl competition in September 2019, during which she played a round with two golfers. Her score was marked by opponent Eva Haupt and when, after the round, she went to log her score in the computer in the clubhouse, she did so using the scores on Ms Haupt's card, which turned out to be wrong. Instead of sixes on holes three and six, the scores had been rubbed out and replaced with fives. Ms Rohilla recorded the fives and was immediately challenged and accused of making the alteration herself. She denied cheating, but the matter was passed on to the club's Captain's Committee and subsequently the General Management Committee (GMC), which terminated her membership. After an investigation, the club found that she had cheated by altering the scores on the scorecard, which she then entered into the computer. But in court, Mr Crow argued that some club members had 'smelled blood' after the allegation and assumed her guilt. He claimed the decision-making process was 'fundamentally flawed' and that Ms Rohilla was not provided a 'fair opportunity' to defend herself as she was not given adequate notice of the case against her. Ruling in her favour after last month's trial, Judge Holmes said the decision to kick her out was a 'breach of natural justice' and 'breach of contract.' However, he said there was 'no evidence to support any suggestion that anyone in the club was motivated in any way by Ms Rohilla's race.' The judge ordered that she be reinstated as a member and awarded £1,000 compensation for 'injury to feelings.' The club began in 1892 and gained Royal status by command of King George V in 1926. It was transformed by five times Open Champion John Henry Taylor into two 18-hole courses across 296 acres of land next to Kew Gardens. Broaden your horizons with award-winning British journalism.
