Probe Israel

Question : Why does Israel yield so much power over the US?
Answer : (1) Financial might of Jewish people in the US. (2) US's cynical collaboration with Israel on international assassinations.

My view is that the Zionists went after the Nazi's involved in Jewish holocaust and once their job was finished they were left with their expertise to neutralize people and no work. Then US, CIA or otherwise, made liberal use of this expertise.

Mahmood Mamdani writes in his Good Muslim, Bad Muslim that role of Zionists in the Afghan war is among best kept secrets.

The US has been a partner in crime.

Europe will not go against US.

Muslim countries should put their act together and we shall get huge evidence about the ill doings of not only Israel but the US too.

Dialogue with a BJP Supporter Professor

 Q: What is the import of temple consecration on January 22, 2024 at Ayodhya in Uttar Pradesh state of India?

A: A pro BJP professor had the following conversation on his Facebook wall.

Title of the Post : Finally the Indian mind has been decolonized

 

Here are some of the comments.

 Mary Anne Cummings

What did I miss?

 

Brajesh Choudhary

Mary Anne Cummings a Hindu temple at the birth place of Lord Ram was vandalised in 1528 by Mughal invader Babar. Today on the same spot after 496 years a grand temple was consecrated with an idol of 5 year lord Ram by the Prime minister of india. For the first time in last 1000 years we could reclaim our temple.

Robin Erbacher

Thank you for the background Brajesh. I also heard in the story that a Mosque that was built on top had stood there for hundreds of years but torn down by crowds 30 years ago, leading to sectarian violence. Then this new temple has been partially built and consecrated today. No idea if I got that right but that’s what I thought I heard (NPR)

Brajesh Choudhary

Robin Erbacher yes there was a disused mosque there on that site. That mosque was built by Mir Baki a general of Babur, the first ruler of Mughal dynasty after destroying the temple at the birthplace of Rama in 1528. 1n 1992 on 6th December the disused mosque was pulled down by Hindus. The courts of india heard the case for almost 150 years from British days till 2019. In 2019, a constitution bench of the the Supreme Court of india gave a 5-0 verdict that there was ample proof that under the mosque if any structure existed it was a temple. The disputed land was given to Hindus and the Muslims were given 5 acres of land elsewhere just to soothe their feelings.

The Muslims have destroyed about 40000 temples in india. When you go to Indian temples and archeological sites and see broken hands, legs, face disfigured of the statues, all of them were largely done by Muslims because they don’t approve of idolatry. Robin, I hope you saw that at Elephanta when you were in Bombay.

Robin Erbacher

Mani Tripathi it was a brief story. They may have had it right, I was distracted a bit.

Maripat Abu Adil

Brajesh Choudhary The Archaeological Survey of India (ASI) excavated the Ram Babri Mosque site at the direction of the Lucknow Bench of the Allahabad High Court in Uttar Pradesh in 2003. When the thick report came out Professor Irfan Habib reviewed it in a talk at the Institute of Objective Studies at Aligarh (not related to AMU). I was present in the talk. There was no evidence of the Mosque being built at the sight of a temple.

 

Brajesh Choudhary

Maripat Abu Adil Let’s not quote Irfan Habib the Islamist professor. The mosque was called masjid janmsthan. It was built in 1528 by demolishing the temple. The Supreme Court said that there was definitely a temple till 12th century and the remains under the temple were all of Sanatan culture and not Islamic. The birthplace was decided by the SC based on Skanda Puram which is mentioned in the report nearly 20 times. Please don’t quote selectively and never quote that charlatan if a historian Irfan Habib.

 

Brajesh Choudhary

Maripat Abu Adil if you need the SC report, please send me your email. I will be happy to send you the pdf file.

 

Maripat Abu Adil

Brajesh Choudhary It is well known that Professor Irfan Habib is Marxist historiographer. People have differences with Marxist intellectuals but no serious person has ever accused them of being charlatans. Intellectuals with Saffron bent of mind are very biased about social, cultural and political issues. Hence their words about any one else apart from their own ilk carries no weight. Finally it is in public knowledge that the Supreme Court gave away the Masjid land in deference to the sentiments of the majority community. This is what your foreign FB friends should know.

 

Brajesh Choudhary

Maripat Abu Adil no you are wrong. The land was given based on birth place of Lord Rama based on Skanda Puran. Please don’t try to wordsmith. Read the report. If you need it, just send your email and I will send the SC judgement.

 

Maripat Abu Adil

Brajesh Choudhary Is it not appeasement of majority community on part of the Honourable Supreme Court of India to give Masjid land for the construction of temple on the basis of Skand Puran?

 

Brajesh Choudhary

Maripat Abu Adil Sir if you don’t know the culture of this country it is not my problem. India didn’t become a country in 1947, it has existed for millennia. The Hindu scriptures tell the story of india that existed prior to Muslim invasion and domination. Skanda Puran based information was just one part of information based on which SC gave its judgement. The other was ASI report that if there ever existed a structure under that so called mosque called Babri masjid it always was a temple. The history has recorded that Mir Baqi general of Babur demolished the temple in 1528. The mosque has been always called Masjid Janmsthan. Sir how much proof you need? Why you take pride in a structure which reflected Hindu humiliation and subjugation? I don’t understand.

One more fact. You know that Babur had a toy boy lover called Babri. He named that mosque on the name of his boy lover. Do you really want that? Maripat think about it.

 

Maripat Abu Adil

Brajesh Choudhary We know the culture of this country. The normal historical process brought India under Muslim rule. If it was subjugation that can be debated. Humiliation it was not. If it was humiliation then Man Singh and Birbal would not be with Akbar and Hakim Khan Sur with Maharana Pratap. But let us stick to Babri Masjid. Since the land was given to the majority community on the basis of Skand Puran then it was appeasement of the majority community.

 

Brajesh Choudhary

Maripat Abu Adil you have your freedom to believe. The land was given on historical facts one of which was Skanda Puran too but if you want to negate historical facts it is your choice.

 

Maripat Abu Adil

Brajesh Choudhary No brother historicity is not decided on the basis of scriptures but archeology and the answer from that criterion is that there was no temple below the Mosque.

 

Brajesh Choudhary

Maripat Abu Adil the remains under the mosque was not Islamic but Hindu. That’s also true. So how a mosque came on that. If you want still to believe in Babur and Mir Baqi, I can’t help. Carry on. You have freedom to believe.

 

Maripat Abu Adil

Brajesh Choudhary Now my brother I suppose your foreign friends will have my point of view too and it is up to them to believe whom so ever they want to.

 

Brajesh Choudhary :

Maripat Abu Adil sure you can write your point of view. If I was worried with your views and what my foreign friends will think then I would have deleted your response but it is the tolerance in me that accepts all views but the truth of Islamic violence, barbarity and dehumanisation of Hindus in india or parts of india for 800 years can’t be negated. Its written all over india in its broken temples, burnt university, destroyed statues. It’s so sad that today’s Indian Muslims who have nothing to do with the invaders except that their forefathers changed their religion either out of fear or to seek favour still believe in those barbarians. That’s the biggest tragedy of modern India. And I am sad that you are one of them.

Holographic Entanglement Entropy - 10

My present concern in this regard is the following : Can we use Tomita-Takesaki modular theory to derive the Page curve? In other words can we exploit the findings of CPW=Chandrasekaran-Penington-Witten to give a new derivation of the curve followed by the black hole entropy?

Holographic Entanglement Entropy - 9

Here is the overall view of the CPW=Chandrasekaran-Penington-Witten paper.

1. Leutheusser-Liu studied large N limit of thermal correlation functions of single trace CFT operators.

2. Further progress was made by Witten in Gravity and Crossed Product [arXiv:2112.12828[hep-th]]. This converts the Type III von Neumann algebras to Type II(infinity) algebra.

3. Above construction has a limitation and what CPW do first is to remove it.

4. Then they go over to the GSL=Generalized Second Law of blackhole thermodynamics.

5. Finally they apply their results to a thought experiment with black holes and wormholes.

Holographic Entanglement Entropy - 8

Question : What are von Neumann algebras doing in this business?

Answer : In an article called Notes on Some Entanglement Properties of Quantum Field Theory Rev. Mod. Phys. 90(2018) 45003 [arXiv:1803.04993[hep-th]] Edward Witten answered a host of such questions.

The main idea is that when we make the move from quantum mechanics to quantum field theory entanglement is not merely a property of quantum states. Now it is elevated to a property of the operators acting on these states and hence to the algebras of the observables.

Witten's article is about explaining these issues.
Thankfully von Neumann already gave us the answer to some of the mathematical questions.

Witten collects many other essential mathematical details.

Holographic Entanglement Entropy - 7

My interest in this topic arose because Gautam Sengupta was excited by the appearance of the CPW = Chandrasekaran-Penington-Witten paper [arXiv:2209.10454[hep-th]] entitled Large N Algebras and Generalized Entropy.

This paper is a repetition of the earlier mentioned works on the proof of the QES proposal without using replica trick or Euclidean gravity.

They use Tomita-Takesaki modular theory to this end.

Holographic Entanglement Entropy - 6

The introduction of the Quantum Extremal Surfaces (QES) and the Generalized Second Law (GSL) of blackhole thermodynamics paved the way for the derivation of the Page curve.

This was done in parallel by Almheiri-Engelhardtt-Marolf-Maxfield as well as Penington in 2019.

Page curve is the curve followed by blackhole entropy and in deriving this we get the result that quantum information is not lost in the process of blackhole evaporation.

Holographic Entanglement Entropy - 5

Perhaps the most remarkable application of the concept of holographic entanglement entropy has been in the field of black hole entropy studies.

In 2014 Engelhardt and Wall introduced the concept of QES=Quantum Extremal Surfaces that are used in the definition of GSL=Generalized Second Law of blackhole thermodynamics.

Why should the QES proposal be right? Hints to this question are provided by tensor network toy models and a close relationship between QES proposal and quantum error correction.

The Ryu-Takayanagi proposal was extended to time dependent states by Hubeny-Rangamany-Takayanagi.

Swingle as well as van Raamsdonk argued that the essential building blocks of spacetime geometry should be related to entanglement structure. 

 

This opened up the door of the reconstruction of the bulk geometry from purely quantum considerations. Susskind-Maldacena dictums like ER=EPR are related to this aspect.

 

Faulkner-Lewkowycz-Maldacena proposed quantum corrections to HEE in 2013.

Holographic Entanglement Entropy - 3

 

The 1997 AdS/CFT correspondence conjecture by Juan Maldacena connected theories of gravity on AdS spaces and compact manifolds to the quantum theories without gravity on the boundary.

In 2006 Ryu and Takayanagi exploited this to define holographic entanglement entropy.

 

This has lead to very vigorous investigations into entanglement in quantum field theory and quantum gravity.

Holographic Entanglement Entropy - 2

There is entanglement in quantum mechanics. This was honoured by 2022 Nobel Prize.

 

Then there is entanglement in quantum field theory. This is a paradigm shift from entanglement in quantum mechanics.

 

Finally there entanglement in quantum gravity. This too is a different game.

Holographic Entanglement Entropy - 1

One year ago Gautam Sengupta's students were talking about some topics like ones in the shared post.

Some of these are connected with with the holographic entanglement entropy defined by Ryu and Takayanagi.

 

At that time I felt sort of left out though I had already spent time with Witten's article on entanglement concepts in quantum field theory.

 

One year later I feel less like Alice in Wonderland. My third student is doing her MSc project on related topics.
