In world record, Bolt triumphed over air

July 26, 2013

Bolt_triumphedParis, Jul 26: Scientists today said Usain Bolt performed a feat of biomechanics when he ran 100m in a record 9.58sec at the 2009 World Championships in Berlin.

Crossing the line in a time that is still a world record meant Bolt had to muster "truly extraordinary" power and energy to overcome exceptional drag, they said.

Taking into account the altitude of the Berlin track, the temperature at the time of the race and the resistance caused by Bolt's 1.95m (six feet five inch), 94-kilo (207-pound) frame, the researchers calculated he had a drag coefficient of 1.2, which is less aerodynamic than the average human.

Bolt hit peak power after only 0.89 seconds, expending 81.58 kilojoules of energy by the time he finished the race.

But 92.21 percent of this energy was used to overcome air resistance, according to a paper appearing in the European Journal of Physics. Only 7.79 percent was used to achieve motion. After 41 strides, he crossed the line at 43.92 kilometres (27.29 miles) per hour.

"The enormous amount of work that Bolt developed in 2009, and the amount that was absorbed by drag, is truly extraordinary," said scientist Jorge Hernandez from the National Autonomous University of Mexcio.

"It is so hard to break records nowadays, even by hundredths of a second, as the runners must act very powerfully against a tremendous force which increases massively with each bit of additional speed they are able to develop.

"This is all because of the 'physical barrier' imposed by the conditions on Earth. Of course, if Bolt were to run on a planet with a much less dense atmosphere, he could achieve records of fantastic proportions."

The team compared Bolt's time in Berlin with his previous world-record time, of 9.69sec, set during the 2008 Beijing Olympics. In Berlin, he benefited from a tiny tailwind of 3.23 kph (2 mph), the researchers found.

Without this boost, he would have come in at 9.68sec, thus beating the previous mark by 0.01sec. The analysis was made from data provided by the International Association of Athletics Federations (IAAF), whose laser tracker recorded Bolt's position and speed every 0.1 of a second in Berlin.

Washington D.C., Jan 6: 'The Irishman,' and 'Two Popes' were shut out from the winners list despite getting multiple nominations, the movies didn't win a single award at the Golden Globes Award held on Sunday (local time). Other movies in the list include 'Bombshell,' 'Dolemite Is My Name,' 'Harriet,' 'Jojo Rabbit,' 'Knives Out' and 'Little Women.'

According to The Hollywood Reporter, 'The Irishman' may have gone into the 2020 Golden Globes with the second-highest number of film nominations, tied with 'Once Upon a Time in Hollywood' with five nods, but Martin Scorsese's highly anticipated mob epic for Netflix was completely shut out at the award ceremony.

Netflix landed the most film nominations of any company with 17 mentions, but it won only one award which is the best-supporting actress for 'Marriage Story's' Laura Dern. Netflix's nominated films 'Dolemite Is My Name' and 'The Two Popes' was tied with 'Joker' with four mentions each and failed to grab any awards.

'Dolemite Is My Name' star Eddie Murphy was expected by a number of pundits to win for best actor in a motion picture, musical or comedy.

'Bombshell', 'Harriet',' Frozen 2', 'Jojo Rabbit', 'Knives Out', 'The Lion King', 'Little Women' and 'Pain and Glory' are among the other films that received multiple nominations but didn't win a single award.

On the TV side, Netflix's 'Unbelievable' tied in the race to most small-screen nominations with 'Chernobyl' and 'The Crown' with four nominations, and 'The Crown' won only one award, for star Olivia Colman.

The three-time nominees 'Barry', 'Big Little Lies', 'The Kominsky Method' and 'The Morning Show' also didn't grab any award. 'Catch-22', 'Killing Eve', 'The Marvelous Mrs. Maisel' and 'The Politician' who were two-time nominees that were also iced out.

'Hustlers' star Jennifer Lopez failed to take home the best-supporting actress award as she was predicted to win the award by a number of pundits. Billy porter also failed to make history with the best drama actor win for his role on 'Pose,' if he would've won the award, he reportedly would have been the first openly gay African-American to win that award.

'Chernobyl' won two of its four nominations. Despite that, star Jared Harris didn't win the best actor in a limited series Globe which was predicted by many prognosticators. The award was bagged by Russell Crowe for his portrayal of Roger Ailes in 'The Loudest Voice.' But the star was absent from the ceremony.

Indore, Jan 7: With the first T20I being washed out, India and Sri Lanka will now hope that rain gods stay away from the Holkar Stadium when the two teams face each other in the second match of the ongoing three-game series on Tuesday.

Only toss could take place on Sunday at Guwahati`s Barsapara Cricket Ground before rain gods came in and left damp spots on the pitch thus forcing the game to be called off without a ball being bowled.

Hairdryers were used to dry the pitch after water seeped in through leaking covers at the Barsapara Stadium, a sight which is not usually seen in international cricket. And that hasn`t gone down well with the Board of Control for Cricket in India (BCCI) which now awaits chief curator Ashish Bhowmick`s report on the same.

The Men in Blue, who enjoyed a brief break, are coming into the series on the back of T20I series victories against Bangladesh and West Indies respectively and thus would be the more confident side out of the two.

Just like Guwahati, the team management and other Indian cricket fans would focus on comeback man Jasprit Bumrah who is making his return to international cricket. Bumrah has been out of action after India`s tour of the West Indies in July-August due to a stress fracture on his back and thus would be rearing to go and perform for the team.

Dhawan, like Bumrah, was not part of the West Indies series after he hurt his knee during the Syed Mushtaq Ali Trophy. The left-handed opener was not at his absolute best in the T20I series against Bangladesh and faced criticism from several quarters.

While Bumrah will grab more eyeballs during the remaining two matches, the series is also important for left-handed opening batsman Shikhar Dhawan, making a comeback into the team post knee injury.

However, recently, he scored a century in the Ranji Trophy and showed glimpses of returning to form.

In the bowling department, the team management would be checking out how the likes Navdeep Saini and Shardul Thakur react to pressure situations in death overs alongside Bumrah in the absence of frontline speedsters Mohammed Shami Deepak Chahar and Bhuvneshwar Kumar.

Young-off spinner Washington Sundar would like to put up performances to ensure that he gets to be part of the squad travelling to Australia for the World T20 in October.

Shivam Dube would also like to perform better - both with bat and ball - till Hardik Pandya is fully fit and back in action.

Wicketkeeper-batsman Rishabh Pant - like recent times - will once again be watched with careful eyes. Pant knows that he cannot take things lightly and need to perform as Sanju Samson as already warmed the benches for six straight T20Is.

For Sri Lanka, the remaining two matches of the series would be about giving match practice to the likes of Angelo Mathews who is returning to the national side having last played a T20I against South Africa in August 2018

In their last T20I series, Sri Lanka suffered a 0-3 rout in Australia as all their three departments failed to put in a commanding performance.

India and Sri Lanka have faced each other in 17 T20Is, out of which India have won 11 -- joint most for them against all opponents faced in shortest format.

With the three-match series now effectively turning into a two-game affair, both India and Sri Lanka would want to win in Indore to make sure they can`t lose the series. Also, Sri Lanka have never beaten India in a bilateral T20I series, a record which they would desperately like to change in the remaining two games.

Squads:

India: Virat Kohli (c), Shikhar Dhawan, KL Rahul, Shreyas Iyer, Rishabh Pant (wk), Ravindra Jadeja, Shivam Dube, Yuzvendra Chahal, Kuldeep Yadav, Jasprit Bumrah, Navdeep Saini, Shardul Thakur, Manish Pandey, Washington Sundar, Sanju Samson.

Sri Lanka: Lasith Malinga (c), Dhanushka Gunathilaka, Avishka Fernando, Angelo Mathews, Dasun Shanaka, Kusal Perera, Niroshan Dickwella, Dhananjaya De Silva, Isuru Udana, Bhanuka Rajapaksa, Oshada Fernando, Wanindu Hasaranga, Lahiru Kumara, Kusal Mendis, Lakshan Sandakan, Kasun Rajitha.
