Where were we: Boaz Barak proposed a “law of nature” that if there is a physical device that can make a certain computation C, then there is a quantum circuit that computes C. 1/11

@boazbaraktcs @quantum_aram @AspectStalence @RosenblumSerge

Aram remarked that Boaz's proposed law is a variant of the strong Church Turing thesis. Correct! 2/11

I proposed a refinement of the general law. There are cases where we can analyse classes of devices (or natural processes) and can conclude that for them there is even a classical circuit that computes what they compute. 3/11

I gave a few examples 1) Computations that take place in Boaz's laptop can be carried out by a classical circuit.
4/11

2) Computations carried out by Boaz's brain can be carried out by a classical circuit. 5/11

Here is another (plausible) example: 3) Protein folding for proteins occurring in nature can be described by classical circuits. 6/11

Boaz responded that “nature” does not have a notion of a “classical device” - nature is quantum. 7/11

This is a nice slogan but it is irrelevant to the fact that *we* can recognize physical devices or fragments of quantum physics that can likely be described by classical circuits. 8/11

In a 2014 paper Kindler and I considered noisy boson sampling. Based on some noise model that we described we concluded that such devices could be described by classical circuits. 9/11

One plausible conclusion that we offered was that it is unlikely that photonic boson sampling devices would exhibit huge quantum computational advantage (HQCA) just like it is unlikely that Boaz's brain or Boaz's laptop will exhibit HQCA. 10/11

My general argument regarding NISQ systems extends this interpretation of our 2014 results. Boson sampling is conceptually and technically simple.

In the cold light of morning, I'm still completely amazed by the legal belly flop that @ThomasMoreSoc filed in the DC District Court. It's the legal equivalent of watching the butt fumble, live

EVERYTHING you could possibly get wrong in a complaint, they managed

Start with the plaintiffs. The ONLY claims in the lawsuit are that the Constitution gives state legislatures the right to set the manner of elections, which they have allegedly (we'll get to this insanity) failed to do.

There's oodles of caselaw saying "since that's a right of the state legislature, only state legislatures, as a body, can bring such a claim"

Are the plaintiffs state legislatures?

https://t.co/KJGEvm8Owp

OK, what about the Defendants? They've sued Defendants from, IIRC, five states (GA, PA, WI, MI, AZ) based on claims that the State Legislatures there didn't pass election rules that the plaintiffs insist the Constitution requires (I promise, we'll get there).

It will be taken up once item 301 is over : Counsel

We will proceed. Did the meeting take place : Court

Yes, it did. Mr Mehra is appearing before Surpreme Court: Adv Satyakam urges Court to take up the matter little later.

Maharaja Agrasen Hospital, adv Alok Aggarwal: We have ICU beds and emergency beds. We don't charge emergency patients for oxygen. There is a notice to Hospitals saying we have to attend to all emergency patients within 10 mins and give them oxygen and medicines.

There is no one who is able to tell us there are people supposed to go if we can't admit them. We are full. They can't keep on occupying emergency area.. I can't kill a person because I've to admit another patient : Aggarwal

Edmonton Against Fasci...
@EdmontonAgainst

In late October 2020, the Edmonton Proud Boys appeared at a People Vs. Predators rally.

One member of this @splcenter-designated hate group is John-Clayton Wilson/Jay Wilson/JC Wilson/JC2theW. (1/10)

@DoxerPb @RuthlessWe @AntifaGarfield @AntiFashGordon @AntifascistF12

JCW is an artist and performer, having done trapeze work. He also operated a YouTube channel, which provides men's rights activist analysis of feminism and the LGBTQ+ community, despite being a member of that community. (2/10)

It's hard to know why JC joined the bigoted Proud Boys, but JC's history of men's rights activism and anti-feminism help the connection make sense.

Here's a sample of some video topics. The language and themes align with the far-right. (3/10)

Still, JC being a member of the LGBTQ+ community makes his decision to join a hate group puzzling for us.

Not that this is unheard of, of course, but these people are not your allies. They aren't even allies with each other and we see this play out all the time. (4/10)

We gave JC multiple chances to get in touch so we could connect him with resources and people who specialize in leaving hate groups. He got the message, but he responded by changing his name and trying to hide his accounts

It's not too late to leave. We can delete tweets. (5/10)

Short thread on impeachment witnesses:

First, let’s remember that this case had unusual and powerful evidence in the public record. If you are prosecuting a bank robbery and you have the surveillance camera footage, you don’t need witnesses to tell you what happened.

1/

Second, the only areas where witnesses could help was confirming what the circumstantial evidence already showed about Trump’s knowledge and intent, both before and after the riot. Mgrs did great job of using his own tweets to show his knowledge but witnesses could confirm.

2/

The case was really strong as is but new witness testimony would very likely become the sole focus of the media and the public. For that reason, it is especially important to avoid taking risks with witnesses a) who are adverse to you and b) whose testimony is unknown.

3/

Since the only witnesses that would be helpful are ones close to Trump, executive privilege would invariably be an issue. If a witness is not cooperative, s/he would likely fall back on EP to avoid testifying. Hashing that out would take months.

4/

The reality is that Trump has created a dynamic through the Ukraine whistleblower and Ukraine witnesses where his domestic terrorist supporters threaten violence against witnesses against him. This fear is real and it is a huge problem. This should be everyone’s focus.

THE IMPORTANCE OF DEVI BEEJ / BIJA MANTRA.

Once Suutji in his discourse with King Janmajeya repeated the words of Vyasji regarding the pronounciation of the word ऐ. Vyasji had heard the importance of this word in a meeting of all important saints at Naimisharanya.

There this story was discussed.

In that gathering of such great sages, Rishi Jamdagni asked a question to all the eminent luminaries. He wanted to know which diety is the most revered and gets satisfied easily with our prayers. So Lomash rishi replied that Devi

Bhagwati was one such diety. She will be satisfied and is ready to grant you a boon even if you just say the first letter of her beej mantra. In this context he narrated the story of Satyavrat. The story is as follows.

There lived a Brahmin named Devdutt in Kosal.

He was childless. He arranged for an elaborate yagya for a intelligent son to be born. He invited all the eminent rishi's to conduct this Yagya. Rishi Suhotra, Pael, Brahaspati Yagyavalka were assigned different tasks. Rishi Gobhil was asked to sing the Saamved.

He sang the verses very well, but he had to take respite in order to breathe between two verses. This angered devdutt. He spoke his thoughts to Gobhil rishi.

The rishi got very angry as devdutt did not realise the practicalities of singing. He cursed devdutt that

1)King Porus was a famous Indian king, his real name was #Purushotama. He belonged to PURU tribe mentioned in #RIG_VEDA, the Ancient books of India.

2) Porus ruled the Punjab region and expanded his kingdom between the Jhelum River and Chenab River in the Indian Subcontinent. He was a legendary warrior and more war skills. He made the army most powerful with war skills. Even Alexander had also made difficulty to defeat Porus.

3)Word of Mouth Oral tradition in #Mohyal_Brahmin families since ancient times has kept the Great Saga of their Great Elder known to them as Maharaja “ #Puru” alive.

4) When #Alexander the Great invaded India in 326 BC he was challenged near Taxila by a mere chieftain of the Area. He was King #Porus, a #Vaid_Mohyal. After his encounter with Porus, Alexander met with more resistance near Multan where the forces were predominantly #Mohyal.

5)The Bali rulers of Multan fiercely engaged with Alexander's army in skirmishes in which many senior Generals died. Later during the long and bitter fighting in #Multan, Alexander got hurt by an arrow which pierced his chest ,

ARULMIGU SRI PARTHASARATHY SWAMY KSHETRAM, CHENNAI (TN)

Divya Desha where Perumal appears with moustache of a Sarathi (charioteer) to conduct Arjun’s Rath in Kurukshetra war.
Here, Venkatkrishna-Parthasarthy is present with his entire family.

He is flanked by Sri Rukmini, Sri Balarama, Satyaki, son Pradyumn and grandson Anirudha.
It is said that on the request of Raja Sumathirajan, Sri Perumal appeared and stayed here as Arjun’s charioteer (Partha-sarathi).

He is without chakra as he had promised not to wield weapons in Mahabharata war.
The face has scars caused by Bhishma’s arrows on Arjun. Prabhu took the arrows on himself to protect Arjun.

The Naivedyam offered here does not have spices. Ghee is used in it to cure Prabhu’s wounds. Sarkarai Pongal is famous here.

It is said that Rishi Bhrigu found Devi Lakshmi (as Vedvalli) in Alli flower in the mandir pushkarini. Later, Sri Ranganatha came here to marry her.

The Haas / Force India argument is fascinating, and the decision of the stewards may still have consequences. The first key finding is that the stewards ruled Racing Point Force India to be a valid constructor. That means that it builds its own cars.

Haas had argued that the cars had been designed by Force India, but as Haas knows only too well, "outsourcing" is legal. The stewards decided that "there is no regulatory support for the argument that Outsourcing of Listed Parts cannot come from a former or excluded team."

In determining this, the stewards also came to the following conclusion: "In relation to the submission by the Racing Point Force India F1 Team that it is not a new team, the Stewards decide that the Racing Point Force India F1 Team is indeed a new team."

This will have a big knock on effect for Haas in its continued arguments over the rights of RPFI as relates to its eligibility and rights under the complex payments structure. Haas has argued all along that RPFI should be treated as a new team and tread the same path that it did.

TLDR? Haas lost the fight but may have won the war. In having its argument that Racing Point hadn't designed their own car thrown out, they gained clarification that RPFI was a new team.
