22nd Dec, Winter Solstice Day @ Jantar Mantar, New Delhi

Participate in the Historic Calibration Work of the Jantar Mantar Observatory Instruments!

Be at the Jantar Mantar on the 22nd December, the Winter Solstice Day to participate in the historic calibration work underway for the Jantar Mantar Observatory instruments.

Have you been wondering what exactly are those structure-instruments? How do they tell the time? What other things can they be used for? Et cetera. Then I guess, that's the right platform to interact and know, do and learn, talk-discuss about your doubts, etc.

Further, you can also look through the telescopes there in the evening for certain celestial objects too!

Volunteers from the Nehru Planetarium & the Amateur Astronomers Association, New Delhi will be present at the observatory between 11 am to 5 pm (and maybe little beyond) on the 22nd Dec. They would assist and help-out students and visitors understand the astronomical significance and usage of these instruments. Once again, you should feel free to ask any questions you may have!

From Sunrise to Sunset, the position of the Sun, in the bowl of the Jaiprakas instrument will be traced by volunteer observers (you can be one of them too!!). Why? This will trace out the Tropic of Capricorn in the bowl, one of the markings originally present on the instrument.

Also, at 4 pm starting at the Misra Yantra, there will be a lecture on all the observatory instruments which will be conducted by Dr. Rathnasree, Director, Nehru Planetarium.

Its an opportunity to learn and know, a platform to know something new, etc. and off-course be a part of the historic calibration process.

Anti-gravity


Anti-gravity is the idea of creating a place or object that is free from the force of gravity. It does not refer to countering the gravitational force...

------------------
What we talked about today was something that can be said as negative or repulsive gravity and it has a clear distinction from anti-gravity (rem. the point I raised, to which no one agreed to!). :)

This one is a snapshot of the presentation delivered at the Physics Festival at SVC last year. Here, I focused on introducing a novel invention of the 1930s which is not commonly known even today, highlighted the order of time that could be relevant to research in physics, and the ecstasy and enthusiasm so much a part of the energy that sustains people like us in the subject!

Well, this is a snapshot of the presentation I delivered at KMC last year in their Physics Festival. The main idea was to arouse curiosity and questioning among the audience a.k.a. Think for Yourself. Don't take things as they are, just because your favourite teacher tells you. :)
