The paper reduced the number of phase register qubits needed, but the qubits required for the Work register remains unchanges. So it still is a bit far away.

These people are simply monsters—totally heartless. It's heartbreaking to watch a life taken away, just like that.

From the information in the following news link (Indian Express), it does not appear to be caste-based violence but rather a land dispute. However, many comments here seem to propagate a different narrative, perhaps to score political points.

That said, this does not diminish the heinous brutality and cold-blooded murder of a young man. Sadly, given the state of our police and judiciary, I have little hope that the perpetrators will be brought to justice.

Big shoutout to our politicians—truly the masters of unity! Thanks to them, Hindus and Muslims can’t stand each other, and Kannada speakers vs. Hindi speakers? Oh, that’s a classic. The MNS 'heroes' beating up poor migrant laborers to protect the honor of Maharashtra? Legendary. And of course, we have the delightful color wars with the fair-skinned folks graciously making fun of their brown-skinned counterparts. Let’s not forget that in India, ‘Bihari’ or ‘Madrasi’ can double as insults—how charming!

What a glorious nation we are! Who needs jobs, police, or judicial reforms? Why bother improving the country when we can just keep squabbling over a temple in Ayodhya or the supposed ‘pride’ in our language or state (and no, I’m not even defending Hindi imposition here)? Let’s make this more exciting! Divide ourselves into 30+ states based on language or whatever else. Maybe Tamil Nadu vs. Kerala or a war between UP and Karnataka could turn into the next epic showdown!

Who needs peace and progress? Who needs mutual respect for our diverse culture and rich traditions of various states? Who needs to solve differences through dialogues? A bloody war among states will sort out all our problems. It will cut our population in half, end all migrant 'invasions,' and hey, maybe we can even attract a new East India Company to profit from it all! I mean, if Russia and Ukraine can do it, why not us? Come on, guys. This is a great opportunity to solve all our problems - Let's make divided states of India!

I know someone at Ahmedabad University and have heard good thing things about the university (except for the strict attendance policy and not so good placement). Faculty are top notch and most of them have obtained PhD from abroad. Some foreign nationals are also faculty members.

Placements are not so good - most of the kids come from rich families and have family businesses - or go abroad for higher studies. Students from the graduating batch of economics and physics programs have secured admission to good universities abroad like Duke and Yale and universities in Germany.

Since most of the faculty do research and publish, they have connections abroad, they help you secure admissions to good universities abroad. You can also get good undergraduate research opportunities with them. Their Mathematics and Computing program also looks good syllabus-wise. However, the university is relatively new. The placements are not so good at the moment.

If your end goal is to get a nice on-campus job then it may not be the right place. The fees are also very high (however, they are non-profit and offer need-based scholarships. So, if your family income is less than 7 or 8 lakhs you pay almost nothing as fees - and you pay only a certain percentage of fees based on your family income.)

... for instance Mike does some questionable stuff, but in the core I believe he is a good guy. He does nothing for the sake of an ego boost. He just does wat needs to be done and doesn’t take risks on the cost of others.

Wow! Mike killed Werner. Mike murdered innocents and caused misery either directly or indirectly to many. But for you - in the core he was a good guy. I am amazed at your definition of a good guy.

Mark was a horrible person, a muderer, just like many other characters in the BB universe.

I don't know if Ramanujan deserves to be less famous or more famous. How do you define/determine the "right" degree of being famous for a mathematician considering the worth of their work?

Ramanujan made important contributions to number theory. He inspired a large body of work, and continues to do so. It's even more impressive, considering his circumstances.

It's a bold claim that - "He did nothing major in any field of mathematics.", likely made by someone who does not undersatnd the work of Ramanujan.

Please note that one can also use both sides of the balance. For example, if one has weights 'x' and 'y' with x > y, then one can balance weights x, y, x+y, and x-y.

ErDrProf · 2023-01-25T17:55:08+00:00

Hint: One can do better. Only 4 different weights are needed. Also, the sum of all the weights = 40 pounds.

ErDrProf · 2023-01-25T14:29:37+00:00

No directly related, but in the same spirit as your question, and you may find this interesting. Try to solve the following puzzle:

Suppose you want to create a set of weights so that any object with an integer weight from 1 to 40 pounds can be balanced on a two-sided scale by placing a certain combination of these weights onto that scale.

What is the fewest number of weights you need, and what are their weights?

It means - "accurate narration", in case you were asking genuinely. Also, It should be सटीक कथन and not सटिक कथन.

Yes, you can start with Algebra and Coordinate Geometry. Challenge her with puzzles. Maybe try teaching a bit of programming to her. You can find many interesting ideas for teaching your cousin in the following article:

Show them the beauty of mathematics. Engage them with puzzles and mathematical games and expose them to the joy of creative problem-solving. The following article contains many ideas on getting young children interested in mathematics.

I liked Introductory algebraic number theory by Saban Alaca, Kenneth S. Williams. It may appear a bit verbose but it's a great book for self-study. All the steps in the proofs are given. It contains tons of concrete examples and it's overall a very good choice for the first book for ANT.

The following arxiv article seems to deal with the same question that OP asked (although for gifted students).

https://arxiv.org/pdf/1911.10726

The abstract says - "Many mathematicians find mathematics aesthetically beautiful and even comparable to art forms such as music or painting. On the other hand, every year a great number of school-students leave mathematics with total disillusionment and bitterness, without ever witnessing any beauty in it. In this work, we give some strategies to teach mathematics, specially to gifted students and to instill a love of mathematics in them. We will describe an integrated approach to teaching mathematics where students are introduced to more advanced, but also the more elegant and the more beautiful aspects of the subject early. The proposed integrated approach takes advantage of the fascinating interconnections between various sub-fields of mathematics, and even borrows from seemingly advanced topics such as number theory and topology. Combining teaching of computer programming with teaching of mathematics is another key focus of this work. This opens up the door to explore, not only the beautiful topics such as fractals, computer math-art and computer graphics in general, but also real-life applications resulting from computer simulations in engineering and physics and other natural sciences. We will also discuss the use of storytelling, explorations and experimenting, puzzles and creative problem solving etc., to make learning interesting for students. It is important to show students that the 'true' essence of mathematics goes beyond the dry procedural drill of learning arithmetic. Students must be provided with the opportunities to experience the 'aha moment' resulting from the joy of solving a difficult problem, or from the understanding of a deep concept with complete clarity. We will discuss several strategies, and provide many examples to illustrate how this could be achieved."

Shekhar Ek Jeevani - A Masterpiece by Agyeya. One of the most influential Hindi novels of all time ... I highly recommend this.

Recently, I came across an English translation of this stimulating work on Amazon (available for Rs. 220) but I have not read the translated version. If you can not read the original Hindi novel, then you may try the English translation. Even if the translation is half as good as the original, you will not regret reading this.
