Mangaluru: Vigour and enthusiasm mark ICYM’s Yuva Samavesh 2015

Mangaluru, Mar 26: About 2,771 people are home-quarantined in the wake of the novel coronavirus in Dakshina Kannada district here, Deputy Commissioner said on Wednesday.

"Meanwhile, about 20 people have completed the mandated 28 days of quarantine, DC Sindhu B Rupesh said in a statement here.

More than 38,000 people from the district have been screened and seven are admitted and are under observation, he added.

Bengaluru, Jun 7: An eminent scientist on Sunday suggested a shift system in schools to prevent spread of the coronavirus and continuing with online classes with focus on project-based learning in a big way to promote creativity.

Former Director General of the Defence Research and Development Organisation (DRDO) V K Saraswat supported the idea of online teaching in the absence of regular classes in view of closure of schools due to the COVID-19 pandemic.

But, he said it should be organised in far better and more interactive ways so that delivery of knowledge can be better. The NITI Aayog member stressed the need for schools to have a strategy when they reopen keeping in mind the safety of students.

May be they will have to organise shifts so that within the same space they can handle the students; May be they will have to employ more teachers, and they can run two shifts. "May be half the strength in a class can come in the morning and others in the afternoon.

Or students of first to sixth standard can come in the morning and seventh to tenth can come in the afternoon, Saraswat told PTI. Reopening strategy will have to be worked out by the education department, added the former Chief Scientific Advisor to the Defence Minister.

Along with normal classes, online education should be continued as a regular system in future, and promoted in a big way because that is the way technology is going to help delivery of knowledge, he added. Saraswat also raised the pitch for reforms in the education sector, saying India is facing the problem of rote learning.

Rote learning has to give way for more project-based teaching, he underlined. Children should be made to work on projects at home and that can be done online. That will also support the changeover from rote learning to creative learning.

I personally believe the education delivery system -- primary, secondary and college levels -- has to be completely changed because creativity in India is less and creativity would come only if we replace rote learning with project-based learning, Saraswat said.

On some academics holding the view that the marks-based model is killing the education system in India as it does not promote creativity, he said evaluation of any outcome is important. Even when we perform in our normal way, evaluation cannot be replaced.

Otherwise, you cant find out how much you have succeeded in delivery. Certainly evaluation cannot be dispensed with. He did not agree with some experts, who favoured a single, uniform system for school education in India by dispensing with CBSE, ICSE and state boards. I am not for normalising everything in life.

I personally believe variety should be there. This concept of one kind of a system is okay for a Communist society, society which was trying to drive everybody like a herd, he said.

Creativity comes with variety, and there is nothing wrong in having different kinds of education system, but one thing which is important is we have to integrate vocational training as part of the education curriculum," Saraswat said. Vocational part cannot be kept away from the education system, he added.

Mangaluru, Apr 23: An astronomical phenomenon, ‘Zero Shadow Day', will be observed in Mangaluru on April 24 and in Udupi on April 25. 

According to a press release from Poornaprajna Amateur Astronomers’ Club, the wonder will commence and people will see their shadows disappear for a few moments at 12:28 pm.

The phenomenon is called as Zero Shadow Day. If a person takes a candle in a dark room and use it to create a shadow of one’s palm on the wall, the hand will cast shadow on the wall as one moves the hand. But when one places the palm on the wall, there will be no shadow.

In the phenomenon, the sun at these times shines exactly above the heads on these days. In astronomy, this point is called as Zenith. The point in the sky directly above an observer at any given location. So it is quite clear now that on Zero Shadow Day, the sun passes through the Zenith as a result of which, all objects will have minimal or no shadow if they are on the ground.

The reason for this happens on some specific days is concerned with astronomy. The earth spins around on its own axis and causes days and nights. It also revolves around the sun causing a year. But the seasons are caused because the axis is tilted at an angle of 23.5 degrees. It is because of this tilt that the sun rises every day in the east gradually moving towards the north till June 21st and then slowly proceeding towards the south till December 21st every year. “We call these days solstice. This means the sun shines between the Tropic of Cancer and Tropic of Capricorn every day passing by the equator on the days we call equinox,” the release stated.

As the earth moves around the sun and revolves on its own axis, for all the people between Tropic of Cancer and Tropic of Capricorn, the Sun at noon moves father and closer to the zenith passing through zenith twice causing two Zero Shadow Days per year. People at Mangaluru will observe this on April 24 and August 18 every year and People in Udupi will observe this on April 25 and August 17 every year.

Places with same latitudes will observe the same days of Zero Shadow but the time would vary with longitude. For example, people of Bengaluru as they share the latitude with Mangaluru will also observe it on April 24. While the people of Mangaluru will observe their shadows disappear at 12.28pm, people of Bengaluru will observe this at 12:17pm. Places like Moodabidri, Bantwal, Sakleshpur and Hassan will also observe Zero Shadow on April 24.

Places like Brahmavar, Karkala, Sringeri, Kudremukha, Chikkamagaluru will observe the Zero Shadow Day on the same day as Udupi on April 25.
