*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

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?

“Academic Preparation for College: What Students Need to Know and Be Able to Do” 1983, @CollegeBoard: “In social studies, a grasp of major trends in the contemporary world such as nationalism and urbanization; the ability to recognize historical cause and effect;
a grasp of United States history in terms of the chronology and impact of political events,
development of governmental and social institutions, technological and environmental changes and changes in values.”
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)

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
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.

🧵👇
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.

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.
