Saffron agitators left red-faced as Sullia college principal refuses to ban hijab

Bengaluru, May 27: Amid uncertainty caused by the Covid-19 pandemic, which has disrupted school education in Karnataka, the state government is seeking the help of the Union Ministry of Information and Broadcasting to televise classes, a state minister said on Tuesday.

"We request you to provide minimum three channels on the Doordarshan network exclusively for the Department of Public Instruction, Government of Karnataka," Primary and Secondary Education Minister Suresh Kumar said in a letter to Union I&B Minister Prakash Javadekar.

Suggesting co-branding the channels under DD and the state education department, he asked for the channels to be mandatorily transmitted by the cable and DTH operators under the Cable Act.

The state education department has already discussed with Prasar Bharti officials, who, according Kumar, have assured 3+3 hours of timeslots on the education channel Chandana on cost basis.

"We have also made all the necessary arrangements for content creation by the teachers," he said.

Meanwhile, the minister has revealed that television is the best medium for the students as a home learning mode in these challenging times.

"The department of public instruction reviewed various technological options and considered TV as one of the best means for home learning," Kumar said.

In a survey conducted by the education department, it was found out that 95 per cent households had television sets.

Kumar said the state operates government schools in nine languages, including Kannada, English and Urdu.

"To cater to all the students, and considering a long-term strategy to run schools by maintaining social distancing, we are in immediate need of minimum three exclusive channels to teach through TV," he said.

According to Kumar, the Karnataka government is facing hardships to meet the capital expenditure requirements, hence, it is seeking help from the I&B Ministry.

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.
