Trip to GMRT

Trip to GMRT at Khodad
On our way back from Lenyadri we decided to visit the Giant Meterwave Radio Telescope at Khodad. Since we were going there without an appointment and too on their holiday I was not sure if we would be allowed entry. I was pleasantly surprised when they not only allowed us to visit but also provided their own vehicle for a short trip.
For getting permission to visit check their website http://www.gmrt.ncra.tifr.res.in/ or contact:

These dishes are 45 meters in diameter and weigh almost 80 tons! And there are 30 such dishes at Khodad. Incidentally these are the telescopes.
Fourteen of the thirty dishes are located more or less randomly in a compact central array in a region of about 1 sq km. The remaining sixteen dishes are spread out along the 3 arms of an approximately `Y'-shaped configuration over a much larger region, with the longest interferometric baseline of about 25 km. The multiplication or correlation of radio signals from all the 435 possible pairs of antennas or interferometers over several hours will thus enable radio images of celestial objects to be synthesized with a resolution equivalent to that obtainable with a single gigantic dish 25 kilometre in diameter So effectively we have a telescope that is 25kms in diamter! Its amazing.







The route to Khodad
Reach Narayangaon and proceed in the direction of Nashik. For the route to Narayangaon refer http://unmeshpatil.blogspot.com/2007/10/trip-to-lenyadri-ganapati.html
About 2 kms after crossing Narayangaon you will reach the Junnar phata (Hotel Poonam) on the left. Keep going straight ahead in the direction of Nashik for about 9 kms. On the way you will cross the restaurant and wine bar of Chateau Indage champagne factory on the right side. Beyond that after crossing the 82nd milestone keep looking on the right for the Khodad phata. (The milestone number is written on that side of the milestone which faces the road).
Now when were looking for the direction board to Khodad on the right side of the road we found it hidden by a poster of the popular leader from Baramati. Another example of the politicians misleading us! At the same spot there exists a board for the GMRT too.
After taking this turn proceed for about 4 kms till you reach a crossroad. There is a Mandir on the right side. Turn right. Again at this spot too there are 2 boards pointing to the direction of GMRT –one before the chowk and another at the chowk. Incase of doubt you can always ask the locals for directions to the Doorbin.
Another 4 kms from here takes you to the gate of Tata Institute of Fundamental Reasearch and GMRT on the left side. Both the institiutions share the same campus. You have to register with the Security at the gate. Mobile phones have to be switched off once you are on the campus.
Friday is the day when civilians like us can visit the GMRT. You can also have a paid lunch at their canteen if they have given you an appointment. Facilities at GMRT Canteen are worth as there are no hotels-restaurants nearby 10-15 kms. For GMRT Canteen, cash payment is not accepted. You have to buy coupons from the administration, which will be sold during morning tea time (10:45 to 11:00 Hrs). Also as per user's requirement, Cold drink, Coffee, Bisleri-Water etc can be provided by cash payment or coupons.

There is also a local transport facility from Narayangaon to GMRT. The details are on http://www.gmrt.ncra.tifr.res.in/gmrt_hpage/Local/transport.html
Returning after the visit to Khodad I am full of admiration for the work those guys are doing and full of pride on what India has achieved.

पराधीन आहे जगतीं पुत्र मानवाचा People generally look at Ramayan from a religious point of view. I view Ramayan from a different perspective. Its about human tragedies of epic proportions. Its about the hardships a mature human endures.  This song is Ram's way of consoling and counselling his step brother who is angry at the craftiness of his own mother. He seeks forgivenes and asks Ram to return to Ayodhya and and not proceed to 14 years of exile. Every stanza of this long ten stanza song, brings forth a different truth (some may call it philosophy) of life. Like the first says "None to be blamed, all happens as a result of our past deeds and misdeeds". Yet another stanza says birth and death are those realities of life that no one can avoid. The next says "Death is the eternal truth ... all logic stops its door step". Its about a rightful heir to the throne having to leave the kingdom and make way for his youngest step brother to be the king. This is a force

संदीप खरेच्या कविता

संदीप खरेच्या कविता ..... इतके दिवस मी फ़क्त ऐकले होते की संदीप खरेच्या कविता खूप छान असतात. इथे Calgary मधे weekends ला खूप वेळ मिळत असल्याने त्याच्या कवितांना Google केले। This guy writes good stuff. Actually it is Thanks to dear Sachin Kulkarni that I got to hear Sandeep Khare. The first poem that I heard was "अताशा असे हे मला काय होते ". This is a fantastic piece of retrospection. He has brought about the thoughts of everyone who has thought about his actions of the past. The sight of clouds fighting amongst each other to be the first to drench the earth it clouds our thoughts and finds a way out through the eyes. Absolutely stunning metaphor on the ironies and compulsions of life. Here are some of those that I could. I may have made mistakes in writing the exact words as the convertor that I used was actually an English to Hindi one! Just click on the images to make the poems more readable.

One song inspires many more

One song inspires many more The notes of one song created in 1951 were tweaked by various music directors to create their own version of the original song. Except for the Tamil version (which is similar note by note) others are “different” as they have been tweaked. They retain the original melody but are distinct in their own way. Listen carefully and you will notice that minor changes in notes and scale lead to sweet songs with the same underlying melody. It all started 1951 with Thadi Hawayein Lehra Ke Aaye from “ Naujawan ” sung by Lata Mangeshkar. Incidentally, this was the first song created by Sahir & S D Burman! https://www.youtube.com/watch?v=1jbSep2GbhE Roshan (father of Rajesh & Rakesh Roshan) liked the tune immensely and used it to create Tera Dil Kaha Hai for “ Chandni Chowk ” in 1954 sung by Asha Bhosle and lyrics by Majrooh Sultanpuri. Roshan had complimented SD on his original tune and asked his permission to recreate it in his own way.
