Is the infrared material as good as claimed? Virtually undetectable by an IR camera is a difficult thing..... I did not google this but am curious as to whether this material has a low thermal conductivity, or high specific heat (or both). In effect they have made a good thermal insulator? Heat 'abs...

Given what the KL government has done in the past weeks, Are there Hindus in Kerala who still believe the KL communist party is not anti-Hindu.

In the English version, words facilities and decades are misspelled. Further it say 'money weout in the hundi'....for money we 'put in the hundi.

Hats off to Kl devotees and women in particular who were protesting against a right given to them. Hats-off to both groups, KL men, women- yes. Women were protesting against a right given to them? beg to differ. A decision (based on partial or incomplete knowledge of tradition) was given in their n...

Somehow I was expecting the Muslims in Kerala to support the Hindus here by vocally opposing the verdict. It is a golden opportunity for them to tell the govt to stay out of religion. But they are silent. Any idea why? Is it because they don't want to 'interfere' in a Hindu controversy?.

SriKumar

The above is a limited version of what you wrote. I think you understand enough Hindi to know what has been written. It is not eloquent or detailed, so if you get a better version, go for it. (Other Hindi-speakers, feel free to edit and modify.) It is on you that what you have written above (which w...

Dileep Wait for explanation- प्रिय अयप्पा भक्त केरल सरकार और देवस्वाम बोर्ड द्वारा किए गए कार्यों सदियों से चल रही परंपराओं के खिलाफ है। अयप्पा भक्त, कृपया अयप्पा मंदिर में आएं और पूजा करें। कृपया 41-दिन की तपस्या और अनुष्ठानों का पालन करें। नारियल-घी और सिक्का के पारंपरिक प्रसाद दें। हालांकि हुंडी ...

SriKumar

Dileep I understand now. The context was missing in the Hindi version, probably because your note had to be concise. IMHO, The Hindi version needs perhaps -one- more line saying why the devotees should not drop money. In other words Devaswon will misuse it and more importantly The bigger issue is th...

Dileep- oru suggestion. Why don't you write your message in English and post it here.

So, what would be an exact translation in spirit to Amit Shah's warning: "मैं मुख्यमंत्री विजयन को चेतावनी देने आया हूँ...... तो BJP के कार्यकर्ता आपके सरकार की ईंट से ईंट बजा देंगे" What exactly is this brick by brick thing? THe last line translates metaphorically as: I am warning CM Vij...

Is it possible to calibrate a more precise instrument (e.g.a LIGO) with a less precise instrument (e.g. vibration/seismic detectors). If you are aware of any specific literature on this process for LIGO, I am interested. The Caltech MIT link said that active control of the pendulum system is monito...

It is unbelievable to me that it was allowed to fly (and worse, enter service). If it was allowed to fly the next day, I would assume that neither FAA or Boeing personnel had a chance to examine it.

They seems to have spent time in trying to land at JFK while systems failed one by one that might explain why it went low on fuel. Also for diversion, you not only needs to reach there but should have enough fuel to do couple of passes in case you may not be able to land in very first attempt. Sinc...

SriKumar

I wonder why they didn't declare an emergency. I've been binge-listening to ATC recordings and transcriptions here - https://www.youtube.com/user/victor981994/videos - noticed that less serious issues got the pilots to declare an emergency (I guess to get priority on airspace movements and landing)...

At that time (and placement of Mars relative to earth in 2013) the time for one-way travel of signal was 8 minutes- quoting from memory here. There are some technically incorrect things...one guy talks about escape velocity. The craft did not reach escape velocity (it does not need to). Then he says...

SriKumar

Sure. Will read what you write, Amber.G.
One thing that's interesting is that the linear velocity of earth's surface will keep changing as the satellite traverses north to south and back....so if the satellite wants to stick to one particular longitude it will have to constantly correct for it.

SriKumar

^^^ Why would the location make a difference to the payload? As far as I can see, the launches from Guj. or TN would be in a polar orbit, since there is land on the eastern side (for both locations). For polar orbits, I dont think proximity to equator matters, does it? Earth's rotational push is use...

SriKumar

Agree with the need to shut up T-5 min to satellite ejection. They can talk technical details prior to T-10 or T-5 min. If there's any way to get the word out to ISRO on this point I would like to petition them......I prefer to hear 'parfaarmans naarmal' to the 'vimaan ka pratham charan ab prajwalit...

More details of SSLV. Credit to pgoi (on redditt) . Interesting that the fins control roll. So, are they active? I assume they are active, not sure though. The last-but-one slide talks about roll control for 2nd and 3rd stages, yet there are no fins on these stages. So what's controlling the roll t...

Very informative set of slides, Indranil. Thanks for posting.

SriKumar

Thanks for the clarifications. I was just trying to understand the time-varying aspect of the fringe pattern. The LIGO should be oscillating back and forth due to the gravitational wave, and this changes the fringe pattern as a function of time. Fringes are a essentially a spatial variation of light...

Another link which is good is from Caltech's lecture.. https://labcit.ligo.caltech.edu/~ajw/LIGO_SURF02_4.pdf Very interesting presentation. Wish I had known more physics (topics) to understand some of the slides. I see they used active seismic isolation. What was used as an (absolute) frame of ref...

.And so far I have not read any link as I don't yet have time. Well, I see you had time to read my posts, make posts here (and on other threads too) :D so, let me offer a few lines from the link I posted. The note below is more informative than any of my posts so far. https://www.ligo.caltech.edu/p...

SriKumar

Note that it has been mentioned above as a 'separate issue', after implying earlier how two LIGOs somehow solve the problem of isolating vibrations in any one LIGO). . Note your original question. You were talking about differentiating earth quakes from ligo events, not systemic instumental error. ...

SriKumar

In other words, if the accuracy of one (or both) instruments is suspect, then we dont know what is being recorded. That's what I said right here : The effect of other vibrations masking a ligo event however is a separate issue. Essentially the signal to noise ratio has to be maximized through vario...

SriKumar

A second (or third) LIGO is not going to help if each LIGO is not isolated well from even faint vibrations. Each LIGO instrument has to be absolutely isolated from any vibration given that they are so super-sensitive. An earthquake or other seismic events are going to affect each LIGO differently ....

SriKumar

How are they able to isolate the LIGO from earth's vibrations (I know there's a 10 mile buffer zone or something like that) but at that level of precision, vibrations from earthquakes anywhere on earth and minor plate tectonic movements could affect its functioning? They have 2 ligos spread out geo...

SriKumar

For LIGO, the precision is about BILLION (Yes, a billion) times more ! This is almost unbelievable. IOW i f you take the distance between earth and Alpha Century (4+ light years).. it measures/detects the variation of the order of thickness of a hair. = Just think about that. How are they able to i...

And a 3 km drop did ...
