Delhi proposal for world record for ‘largest practical science lesson’

Published

on

In world record an attempt was made  for the largest practical science lesson by 2,000 schoolchildren from Delhi and the NCR region here on Monday.

The event, jointly organised by Vijnana Bharati (VIBHA) and the ministries of Science and Technology and Earth Sciences, at IIT Delhi was held as part of the 5th India International Science Festival (IISF) 2015.

Fifty students of Class 9 to 12 each were drawn from 40 government and private schools to set the Guinness World Record.

Students conducted two science practicals, both related to catalysis, a process that makes chemical reactions faster without any additional input of energy and is extensively used in manufacturing some 90 percent products used in the world today.

A major feature of the exercise was ‘Elephant Tooth Experiment’ in which hydrogen peroxide underwent catalytic decomposition in the presence of iodide, resulting in the liberation of a large amount of oxygen and foaming up to resemble a giant toothpaste being squeezed.

The other experiment was discolouration of methylene blue by hydrogen peroxide.

Shobit Ranjan, a student from Amity International School, Saket, said: “After a demonstration was given to us, we completed the experiment within 5 minutes. It’s a different thrill to take part in such events and conduct experiments on our own.”

Jyoti Francis, a physics teacher from Salwan Public School,Delhi, said this would encourage girls to enter the field of science. “Such experiments should be demonstrated in the schools as well.”

On the occasion, union Human Resource Development Minister Smriti Irani said efforts were required for similar festivals in all states, and hoped a bigger attempt would be made in the capital in about six months to set the world record of ‘The Largest Practical Science Lesson’.

“Hopefully, 6-7 months down the line, we would be able to make even a bigger attempt at the world record by assembling 20,000 students at the Jawaharlal Nehru Stadium in Delhi,” she said while addressing the schoolchildren at the IIT Delhi..

Union Science and Technology and Earth Sciences Minister Harsh Vardhan and Vijnana Bharati (VIBHA) president Vijay P. Bhatkar also attended the event.

A. Jayakumar, secretary general of VIBHA, said the experiment was conducted in a glitch-free manner.

“All students conducted the experiment successfully. We will be sending the result to the Guinness Book this evening (Monday). Hopefully, the results will be declared by 12th or 13th,”

“for the entire science department in the world it’s a great and motivational message that India can touch much more heights in the field of Science and Technology. It’s an eye opener to the government as well. Through such attempts, students from every district in India will be excited to come forward and join science,” he said.

Twitter acts on inactive accounts, new verification soon

Published

Micro-blogging platform Twitter has started removing blue verification badges from inactive and incomplete accounts and will begin the new verification process for its users in few weeks.

Twitter, which paused its public verification process or that elusive Blue Badge three years ago, in November announced to relaunch verification, including a new public application process, in early 2021.

“Last call! As part of our new verification policy, we’ll remove verification badges from inactive and incomplete accounts,” Twitter Safety said in a tweet.

The company is reading out directly to users who have issues with their accounts.

“We’ve reached out directly to those who need to take action to stay verified,” it added.

Twitter had said it would relaunch verification, including a new public application process, in early 2021.

Verified accounts on Twitter will have a blue check next to the display name throughout the app.

“When we relaunch the public application process in early 2021, there will be a link to the application in the Twitter apps and on twitter.com”.

Over three years ago, the platform paused the public verification programme after hearing feedback that it felt arbitrary and confusing to many people.

A year later, the company deprioritised this work further to focus on protecting the integrity of the public conversation around critical moments like the 2020 US election.

The company has identified six types of accounts in its draft policy as Notable Accounts — government; companies, brands and non-profit organisations; news; entertainment; sports and activists/organisers and other influential individuals.

According to the proposed policy, “the blue verified badge on Twitter lets people know that an account of public interest is authentic. To receive the blue badge, your account must be notable and active.”

Twitter had admitted that there are many verified accounts on its platform that should not be there.

The new verification policy is a starting point, and “we intend to expand the categories and criteria for verification significantly over the next year”.

The draft verification policy is available in English, Hindi, Arabic, Spanish, Portuguese, and Japanese.

“We are also working with local non-governmental organisations and our Trust and Safety Council to ensure as many perspectives are represented as possible,” Twitter said.
