Shakuntala Devi is often described as "India's most famous woman mathematician". Her biopic led discussion like what does a mathematician do? Is mathematics all about performing massive computations? Or is there more to it?
A 🧵on Indian women mathematicians by @kaneenikasinha

 Recall one of the greatest mathematicians of the 20th century: Srinivasa Ramanujan. The image that he evokes is that of someone sitting quietly, writing complicated but beautiful equations involving many symbols in his notebooks.
But, this thread attempts to explore the different things that a mathematician does. Along the way, we highlight some exceptional Indian women mathematicians as examples. #GWOM #womeninmath @GWOMaths @AWMmath
In an abstract sense, a mathematician observes beautiful and meaningful patterns in the universe. Their attempt is to also develop a precise and transparent language in which to explain these patterns.
Discovering and explaining these patterns often amounts to what most of us perceive as mathematics: solving challenging problems. Some problems take several decades and even centuries to solve: in the quest to solve them, mathematicians develop a new language/ techniques. #GWOM
Prof. Neena Gupta is an associate professor of mathematics at the Indian Statistical Institute, Kolkata. A few years, ago, she solved a very difficult, 70 year old problem in algebra: the "Zariski Cancellation Problem".
Prof. Gupta has won several accolades for her work, including the very prestigious Shanti Swarup Bhatnagar Award (awarded to Indian scientists of the highest caliber). Read more about her journey and accomplishments here:

Professor @ParimalaRaman, a senior and very highly honoured mathematician, has made many notable contributions to the study of quadratic forms (at the interface of number theory, algebra and algebraic geometry).
She spent several years @TIFRScience in Mumbai. The first woman to win the Bhatnagar award in math, she was also a plenary speaker at the International Congress of Mathematicians 2010 (one of the highest international honours in mathematics).
Incidentally, the second woman to win the Bhatnagar award in Mathematics, Prof. Sujatha Ramdorai, is a former doctoral student of Prof. Parimala! Prof. Ramdorai has made exceptional contributions to algebraic number theory and arithmetic geometry.
After spending several years @TIFRScience, she currently holds a Canada Research Chair @UBC.
Prof. Ramdorai has also worked with the Indian government in several capacities for mathematics education in India. She was a member of the PM's Scientific Advisory Council from 2009-14.
Producing good research is an important component of mathematics as it leads to new directions which are pursued by the larger research community. But, this is a good time to pause and reflect upon the different ways in which a mathematician can contribute to the nation.
A country like ours has a large number of students who are hungry for knowledge. They seek every possible opportunity to learn and grow: sadly, our educational infrastructure has not been adequate to meet the needs of the future of our nation.
In this context, a mathematician has a huge role in nation building over and beyond their research contributions: by teaching students at all levels, instilling passion for the subject, inspiring/enabling them to pursue their dreams, and by building institutions.
A name that almost immediately comes to mind in this regard is that of Professor Shobha Madan. Professor Madan is a mathematician in the area of harmonic analysis. She has spent several fruitful years as a professor @IITKanpur and is known to be an exceptional teacher.
Today, almost any research/educational institute in India is likely to have a faculty member who studied mathematics @IITKanpur. Many of these IITK students, who became mathematicians in the last few decades, attribute their love for the subject to Professor Madan!
Through her passion for studying and teaching mathematics, Professor Madan has contributed in building several mathematics departments in India. As a distinguished visiting professor @IITGoaofficial , she is now helping to build the mathematics group at this young institution.
We now remember a mathematician, great educationist and institution builder, who essentially started her career with India's independence! Professor Vanaja Iyengar was the founder vice-chancellor of Sri Padmavati Mahila Visvavidyalayam, a university for women in Tirupati.
For her life long contributions to mathematics education in India, Professor Iyengar received the Padma Shri in 1987.
The above were a few examples of some notable Indian women mathematicians. These examples are by no means exhaustive. These are simply a few among several motivated, ambitious and dedicated research mathematicians in India.
These amazing women set the "stage" on fire, not with their computational prowess, but by communicating their mathematical discoveries, knowledge and insights to a large community of students, professional mathematicians and amateurs.
But, they are more likely to be found at their desks, working quietly, with focus and determination, changing the world "one theorem at a time".
Disclaimer: in this thread, we have focused on the practice of mathematics in academia. This, in no way, implies that being a professor or a scientist at a research university is the only way to practice mathematics.
Mathematics has widespread applications in the "real" world; for example, cryptography, data sciences, space science. But, to paraphrase how a mathematician typically concludes a research article, "we relegate this theme to a future work." :-)

Ok, it's time for a #FUNctionalAnalysis thread! Let's talk about Hilbert spaces. (I hope you like linear algebra, because that's what we're


If you want to impress people, you can just say a Hilbert space is just a complete infinite dimensional inner product space and leave it at that, but let's talk about what that actually means.

When you first learn about vectors, you talk about them as arrows in space; things with a magnitude and a direction. These are elements of R^n where n is the number of dimensions of the space you care about.


You also talk about the dot product (or inner product) as a way to tell when vectors are orthogonal. (I'm purposely saying "orthogonal" instead of "perpendicular" here, but when you actually think about arrows, it's the same thing.)


As my linear algebra students are about to see, R^n is far from the only interesting vector space. A classic example is the space of polynomials of dimension less than or equal to n

The key to teaching division to young students who have only been introduced recently to more complicated mathematics forms is to make the student feel involved with the process, while finding it pleasant at the same time.


Mathematics worksheets are effective, but there are other ways in which mathematics can effectively teach. This is practically the generic form of teaching that demonstrates being more effective among children and young people.

No matter how many times make the child complete a division worksheet, or produces division assignments, there is no promise that this child can deliver continuously with the ability to perform successful division problems.

The resolution of mathematics problems is easier when you have the right resources. But what are the right resources? The answer depends on who you are, what you are trying to achieve, and why.


Are you looking for specific information that will be used once; Or exhaustive understanding, in depth that you will use in the future?

Math action like drill and practice help a kid increasing great mental number aptitudes. In addition, if the training is done regularly through playing around, youngsters effectively get acquainted with numbers.


These days, we have various online numerical exercises implied for kids and the adults the same. Instructors, guardians and youngsters have various games and number drill exercises close by.

So okay, here's a thread on the category of finite sets and a way in which it controls algebraic structure in symmetric monoidal categories. I think it's some really pretty stuff.

First let's give some terminology and definitions. I'm going to let Γ denote the category whose objects are finite sets and morphisms are functions of finite sets. There are a whole lot of finite sets so to simplify thinking about this category, I'll work with a "skeleton."

What that means is that I'll just work with isomorphism classes of objects of Γ, i.e. if there is a bijection between two finite sets A and B, I'll think of them as the same set (this can be made categorically precise).

What I end up with then is a category whose objects are countable, namely the set {∅, {1}, {1,2}, {1,2,3},...} and whose morphisms are just functions between these sets. This will be enough to get at some cool algebraic structure.

At some point I might start writing 1 for {1} and 2 for {1,2}, and n for {1,2,3,...,n} but I'll try to let you know that I'm doing it, and hopefully it won't be too confusing of a notational switch.

Some tweets on Adi Shankaracharya and in particular the Guru Parampara of @sringerimath. [I had done this series earlier 5 years ago on account of Shishya Sweekaram].


Adi Shankara established the Sringeri Peetham as the 1st of 4 amnaaya peetams.

The four being
1. Sarada Peetam at Sringeri.
2. Govardhana Peetam at Puri
3. Kalika at Dwaraka
4. Jyothir at Badarikashramam.

He installed his 4 most prominent shishyas as heads of the peetams.

Sureshwaracharya was assigned to Sringeri as its head.

Sringeri is a corruption of Rshyashrunga giri.

Rshyashrunga maharshi [and his father Sri Vibandhaka Maharshi] did their tapas at this place.

It is at Sringeri that Shankara spent 12 of His precious 32 years!!

That gives you and idea how much He loved this place.

Rshyashruga maharshi had a horn on his forehead, a result of being born to a deer. His mere presence was enough to shower rains!!

Rshyashrunga was one who led Putrakamesthi Yaagam of Dasaratha Maharaj and which resulted in Sri Rama's birth!!

Srikanteshwara Temple,
#Nanjangud  #Karnatakatemples 🚩

Srikanteshwara Temple or
Nanjundeshwara Temple is a famous Shiva Temple located in Karnataka at the bank of river  Kapila. Temple is also called Varanasi of South. Nanjunda means one who has consumed poison.


Story is  related to the Samudra Mathanam when Paramashiva had to consume halahala.

Parashurama worshipped Mahadeva here to relieve himself from the curse of Mathru Hatya. While clearing the place to do poojas Parashurama's  axe hit the Shivalingam and it began bleeding, that


mark is still visible even today. Thus
it is also believed that Parashurama did Shiva Prathishta here

Sthala Puranam says that, once there was a demon named Keshi who disturbed the people in the area, after  getting blessing from Brahma Deva  and Mahavishnu. Mahadeva appeared


here and killed demon Keshi and blessed this place as Papa Vinashini. Whoever praying to Srikanteshwara or Nanjundeshwara, after bathing in the  Kabini River will be relieved from all sins.

Nanjundeshwaraya Namah

The first ever world map was sketched thousands of years ago by Indian saint
“Ramanujacharya” who simply translated the following verse from Mahabharat and gave the world its real face

In Mahabharat,it is described how 'Maharishi Ved Vyasa' gave away his divine vision to Sanjay


Dhritarashtra's charioteer so that he could describe him the events of the upcoming war.

But, even before questions of war could begin, Dhritarashtra asked him to describe how the world looks like from space.

This is how he described the face of the world:

सुदर्शनं प्रवक्ष्यामि द्वीपं तु कुरुनन्दन। परिमण्डलो महाराज द्वीपोऽसौ चक्रसंस्थितः॥
यथा हि पुरुषः पश्येदादर्शे मुखमात्मनः। एवं सुदर्शनद्वीपो दृश्यते चन्द्रमण्डले॥ द्विरंशे पिप्पलस्तत्र द्विरंशे च शशो महान्।

—वेद व्यास, भीष्म पर्व, महाभारत


Meaning:-

हे कुरुनन्दन ! सुदर्शन नामक यह द्वीप चक्र की भाँति गोलाकार स्थित है, जैसे पुरुष दर्पण में अपना मुख देखता है, उसी प्रकार यह द्वीप चन्द्रमण्डल में दिखायी देता है। इसके दो अंशो मे पीपल और दो अंशो मे विशाल शश (खरगोश) दिखायी देता है।


Meaning: "Just like a man sees his face in the mirror, so does the Earth appears in the Universe. In the first part you see leaves of the Peepal Tree, and in the next part you see a Rabbit."

Based on this shloka, Saint Ramanujacharya sketched out the map, but the world laughed

ANCIENT BHARAT WAS CALLED VISHWAGURU, AND IT REALLY DESERVED IT.

India had a well developed education system centuries before the westerners arrived and called us uncivilized. Education was always given a great importance in Indian civilisation since times immemorial.


Ancient India had the Gurukulas and Ashramas as the epicentres of the knowledge and enlightenment. Bigger Gurukulas served as the centres of higher education called universities. Besides these universities, temples also emerged as the major learning centres.

Studying the Holy Scriptures, character building, personality development, responsibilities towards self,family and society,discipline and preservation of the ancient culture and heritage were the key embodiments of education.

This kind of education system made ancient India, a centre of knowledge all over the world. Many foreign students came to India for education and India was called the 'Vishwaguru'.
Takshshila and Nalanda were the two prominent universities of ancient India.


But were these only Universities of ancient India?The answer is 'No'.Let's learn about these gems of our education system that flourished across ancient India & be proud.

NALANDA UNIVERSITY
This was the oldest university of ancient India.Situated in Nalanda distt. of Bihar...

For fun I made a Robinhood account. It took me 5 minutes to sign up, get approved and transfer funds for trading...

Here's some details... Read on.

...it took me another 5 minutes to get qualified for options.

If I share a sign up I get "free shares" and I can share as much as I want up to 500$ worth.

The main UI has a prepopulated "list" of stocks/crypto to watch and links to news.


Clicking a stock opens a "trade" button that looks like this.

Notice options is first, buy second.

Options took me to an approval process (which took about a minute) and now away I go trading Baba options.


Buying stock looks like this. It emphasizes fractional shares.
