*Question (research)

within loc compact T2 groups,

+ what makes Lie groups different to prof. groups is that they have a small neighbourhood from which every closed subgroup escapes

+ and (locally) prof. groups don't have such a neighbourhood for open subgroups

(1/x)
It's sad we have to require small subgroups but not for closed subgroups but for something even much stronger

open subgroups

but that also means that there is a structure in between? what is it like?
What are the locally compact Haussdorf groups G such that for every neighbourhood U of 1_G there is a closed nontrivial subgroup H \subseteq U...

...but still there is a neighbourhood U_0 of 1_G such that every open subgroup H of G escapes U_0?

Well @Justin_Bons that is why $DAG exists 😉

Let's explore together how @Conste11ation validates data at the edge and why Metagraphs are the perfect solution for integrating AI with Blockchain

Down the #HGTP rabbit hole 👇 Image
AI is only as good as its data. With the rise of IoT devices and real-time data processing, the need for efficient and scalable edge computing solutions is paramount. Enter HGTP and Metagraphs by @Conste11ation $DAG #AI #EdgeComputing
HGTP, built on a DAG architecture, is designed to handle complex data types and large volumes of transactions. Its concurrent, parallel, and asynchronous processing capabilities make it ideal for handling vast amounts of data generated by edge devices. #HGTP #DAG

The significance of #mathematics in #cryptography is immense. 𝐂𝐫𝐲𝐩𝐭𝐨𝐠𝐫𝐚𝐩𝐡𝐲 involves the process of transforming messages to ensure secure communication. In this thread, we'll explore the integral role of math within cryptography & present some relevant equations (1/9)
One of the simplest examples of cryptography is the Caesar cipher, which shifts the letters of the alphabet by a fixed number. The encryption function can be written as: E(x) = (x + k) mod 26, where x is the letter's position, k is the shift, and mod is the modulo operation.(2/9)
Public-key cryptography is a more advanced technique that relies on mathematical concepts. RSA, a widely-used public-key cryptosystem, involves the generation of two large prime numbers, p and q. Their product, n = p * q, is used in encryption and decryption.(3/9)

She is Gladys West, one of the mathematians responsible for developing GPS, a technology that has changed the way we play, work, navigate, and explore our communities..
"When you're working every day, you're not thinking, 'What impact is this going to have on the world?' You're thinking, 'I've got to get this right,'" West once said in an interview with The Associated Press.
Despite suffering major stroke,heart surgery and cancer,
She was working for most of her life. Now at 92, she has written her memoir and going strong.

Machine Learning is hard.

I felt like quitting whenever I get baffled by the amount of information to learn.

But I followed the path to learning from Math for ML.

Here are the 5 critical reasons why you should start with Math concepts for ML

THREAD🧵 ↓
🤔 Why Math for ML:
**********************
📌 Machine learning algorithms rely on mathematical calculations to make predictions and decisions
📌 Many machine learning techniques, such as neural networks and deep learning, are based on linear algebra and calculus

SRINIVASA RAMANUJAN: An Enigmatic Genius
By K. Srinivasa Raghava.
This December 22 marks the 135th birth anniversary of our own great mathematician Srinivasa Ramanujan-FRS and is observed as National Mathematics Day (GANIT).

How I (a #neurologist) helped a student pass in #Mathematics, which his Mathematics teacher couldn't manage

1. A 15-year old boy was brought to my clinic by his parents asking for some "pill" that would improve his interest and skill in mathematics, enabling him to pass exams
2. He was a bright class 10th kid doing well in all the subjects except in mathematics. His scores were 85-90% in other subjects, with <30% in mathematics. This appeared odd to me. On enquiry, the boy told "my mind switches off when solving complex mathematical problems".
3. The boy continued "my mind keeps on lapsing into absent-mindedness several times during exams" and "before I realize- the time is up". As per his teachers & parents, his answer sheet had many areas of ineligible scribbling. The initial part of answer would be correct though.

There are hundreds of online resources for learning how to code.

But there are much fewer online resources for math.

Maybe that's because LaTeX (the premier math writing tool) isn't good at creating them.

#QuartoPub can do both. So, is it a worthy alternative?🧵 #mathematics
What is Quarto?

Short answer: It's a tool that can create many output formats all from one interface.

That means you can create classical PDF math papers as well as online math books with Quarto.
You may be sceptical about the online part. Maybe you have only seen math in PDF format.

But I assure you that it's a real thing. And it's powerful.

For example, every day hundreds of mathematicians on MathOverflow talk about research-level math online. mathoverflow.net

⚡Aeroelastic Flutter⚡

The Tacoma Narrows bridge disaster of 1940 attribute the collapse of the bridge due to aeroelastic flutter.

🧵👇
1️⃣ Flutter is a dangerous phenomenon encountered in flexible structures subjected to aerodynamic forces. Flutter occurs as a result of interactions between aerodynamics, stiffness, and inertial forces on a structure.
2️⃣ In an aircraft, as the speed of the wind increases, there may be a point at which the structural damping is insufficient to damp out the motions which are increasing due to aerodynamic energy being added to the structure.

There is a beautiful way to derive the famous Euler’s formula!

In this🧵, I’ll explain a visual, intuitive derivation. It’ll fit into a single picture at the end.

#iteachmath #MTBoS #math #maths #Mathematics An equation with 𝑒^(𝑖𝑡) on ...
This is Thread 3 in a series, but don't worry! This thread is self-contained.
In Thread 1, we saw applications of a mass on a spring.

We solved for its future position, at time 𝑡. This led to 𝑒^(𝑖𝑡), but 𝑖 is "imaginary."

The position along the ground had to be “real,” so we sought to interpret 𝑒^(𝑖𝑡) in terms of real numbers.
