Driving Naari Programme launched in Chandigarh
New Delhi, Have you ever wondered what will happen if all the people on Earth jump together or if a person is born in outer space? These questions may appear to be weird but science has answers for them as well.
There are many popular educational channels on YouTube which provide answers to weird but natural questions and also explain the science behind the events happening around us or far in outer space.
Interesting videos related to the topics of science, psychology, human behaviour and general perceptions are uploaded on these channels.
These short videos can make a long-lasting impact on users by helping them in developing a better understanding of a given topic, experts say.
These videos can explain that if people on the Earth gathered at a particular place at a given time and jumped together, they will feel a slight shaking of Earth, although the intensity of this shaking will almost be negligible on Richter scale.
Greg Foot, a science presenter of BBC performed this experiment with 50,000 people at Reading Festival in the UK and recorded the intensity of the earthquake caused. It had a magnitude of 0.6 on Richter scale.
He then calculated that if the whole population of the Earth jumped at the same time, it will still be a factor of seven million short of changing the speed at which the Earth rotates.
Vsauce, AsapSCIENCE, MinutePhysics, CrashCourse and Scishow are some of the popular YouTube channels among the netizens.
“These videos are good enough to give a logical idea about scientific concepts,” Dr S K Dhaka, Associate Professor at Department of Physics and Electronics, Rajdhani College, Delhi University told PTI.
“There could be a deviation from the expected results but that is close to reality if we do calculations,” Dhaka said.
“Content of video discussing about impact on human body during space residence period is quite reasonable and based on real experiments carried on astronauts,” he said.
However, Dr N S Goswami, Retired Assistant Professor of Chemistry in Delhi University emphasises on classroom studies and demonstrations to get command over the subjects.
“One can watch these videos but in-depth knowledge of any topic and command over the subject requires further studies and research,” Goswami said.
