^^ I did not move anywhere. A nice left over problem is to find the sharp value of the universal constant rigorously. The proof we give just proves there is a universal constant. We are looking at the Rayleigh number regime going to infinity so very large. The engineering and Physics literature as f...

There is a 65 year old conjecture supported by numerical simulations and experiments in the laboratory in Fluid Mechanics, more precisely in Rayleigh-Benard convection. https://en.wikipedia.org/wiki/Rayleigh%E2%80%93B%C3%A9nard_convection One can see these band patterns or hexagonal patterns in clou...

A trial of BOXN freight wagons took place on the WDFC on Dec 20th for a distance of 190km between Phulera and Ateli. The wagons were run at 110 kmph with an average speed of 86 kmph in both loaded and empty condition with 25ton axle load weight. Very few sections of the IR network allow such a 25 to...

Here is a OMAC-Italy tutorial of what you see above ^^^^ Recall from the wave equation the wave speed of disturbances along a wire is of the order of (T/p)^{1/2} where p is the density of the copper wire mass/length and T the tension in the wire. So the tension should be such that the disturbances m...

VSunder, Sir - I had not seen your post before I posted mine. Later I read through your post and realized the mistake!

Rohit thanks. I have a question for you.

Ramana: I am extremely familiar will all this. In fact the very first time I posted on BRF in 1999 was exactly on this topic as applied to Kargil which was raging.

Thanks Ramana. 1965 it seemed to me then that the Pakis would be in Delhi soon dictating terms.

The Pak codename for the Amritsar radar was "Fish Oil". It was a P-30(M) Soviet vintage radar with W/C Dandapani in charge of the 230 Signals unit. Pak AF attacked it many times including a napalm attack on Sept 9 whose sole damage was a burnt tent as AD unit opened up as the bombing run s...

Ramana ji, I look at the 1965 battles slightly differently, though my conclusions are the same. In my opinion the key engagements (series of battles) were: 1. Pre Sept 65 - dealing with Pak infiltrators and capture of Haji pir : Victory for India. 2. Pak attack in Chhamb towards Akhnoor - Draw. Pak...

All that damage only by 2 armored cars. IA at its best myth making form. Thank god IA did not state they accomplished it by two guys using slingshots like David. I just saw David in Florence.

A few more comments. I dug up the video about Mehar Baba, not the saint but the IAF Air commodore.

... Sharda Mukherjee was a stunning and elegant woman. She was a Maharashtrian woman. Later she became Governor of AP. Bharathi Mukherjee, IIRC, was the Governor of AP.

Deans absolutely agree with you. I knew many of the people who fought in the 1948 operations. One could not but growing up in Kanpur in the late 1950's.
