A really good book, for people interested in learning about lie groups.

I was studying linear algebra and was reminded of this book that I bought some time ago. I haven't finished it (2 chapters in) but the introductory concepts coupled with my random study of SU(2) group and its algebra gave me some rudimentary insight into the utility of Lie Algebra's and why it was good enough to be used for Pauli matrices and describing spin, but not good enough to be true vectors in 3-d+1 time space.

For those interested, there is also a good channel that goes over the boom in-depth and you can pretend youre a graduate student getting lectures and working problems from the book as homework.

Here is thw link

Really good book

Bought this book after seeing it referenced in Jackson's "Classical Electrodynamics" and so far it is wonderful. I have only grazed the surface, but just from the concise and explicit definitions given it seems wondeful. However, there is only slight intersections with Electrodynamics since the topic covers optics rather than the general topic of electromagnetic phenomena.

The book is called "Principles of Optics" by Born and Wolf.

I like this book. I hope to buy it one day.

Russel, makes reference to wittgensteins constructs vaguely. I recommend checking out logicus tracatus philosophicus as it is an interesting contribution to the formation of logic as a teue discipline of mathematics and when the world finally had a cohesives train of thought that cemented mathematics as another ideology created by humans. Not this mystical construct with non-contradictory extensions of original axioms of ideology.

Hopefully one day I can get lapacke working and build fancier.

which one do you think is harder? Putnam or International olympiad?

the power of linear algebra and the analysis of transformations

Ill post my code later.

Hints:

The growth can be found using a recursive series and the associated logic.

Will require a for loop.

I remember having a discussion with one of my math peers about floiting point error but it seems different than that. For example in c++

#Include <iostream></iostream>

#Include <cmath></cmath>

Using namespace std

Int main ()

{

\ declaration of string value

string X=" "

\ ui to get an input

cout << "Enter a numerical value";

cin >> X;

cout << "\n" << endl;

*conversion, redeclaration with associated values *\

const double pi =3.1415

double stragcel = stof(X) * pi * 2

\ print of your cute twinkry

cout << "The amount of cute twinkry in your soy titties is " << stragcel << " inches squared. You might wanna get that checked out." << " In terms of the range of the oscillations of your cute twinkry it is " << sin(stragcel) << " to " << sin(-stragcel) << ". This is dangerously off the charts. We cannot help your cute twinkry, sir." << endl;

return 0;

}I have done similar things with floating points but the error seems to be constant with int, float, and double. What is it?

A good book for those that want an overview

To the mathematically inclined this book has presented value to me so far.

It isnt a book one should expect to read in on session or even in a couple of months of pure devotion. Instead it is material that should be reviewed and digested in conjunction with one's own studies and pursuits. It covers a vast variety of topics found in pure maths, but the real meat that one can chew on is its discourse on the philosophy of maths, techniques used to be a mathematician, and the historical mentions.

Kinda expensive though. 64 bucks.

Congratz to the physics nobel prize winners for 2022

Most of the nobel prizes are b.s. political trash, but science is less affected with the trash of humanity. The physics winners goes to the three people that shown that bell's inequality can be broken with a specific experimental set-up, the person who did the experiment, and the person who applied it to create quantum computing. If microscopic engineering improves and current atom by atom materials construction techniques can be industrialized we may see a phase of technology where the spin parity of photons instead of electrons can be used for quantum computing. Of course reality limits technology, but innovation uses limitations to create technology!

Some fun problems to kill time

Im not going to do them cause I've already done them. But here ya go! Taken from "Introduction to Real Analysis," by William Trench

Some texts that I like that go over "simple" content but hold valuable wealth

I enjoyed them. The first book is good on its own, supplemental resources arent really needed and the main citations are from direct translations. The second book is really big and long amd goes in depth on newton's "principia naturalis..." Researching the cited sources in conjuction to the text is actually extremely useful. Especially, for those not acquainted with the old school of thought in mathematics and the pedagogical rigor that it contains.

Math monday

This problem is more computationally proofy. I had fun with it. Mind you, youre solving the character polynomial associated with a second order diffy eqn with monomial constants with the substitution y=x^m.

Have fun, if you get it right ill give you boob pictures.

Seriously though, go through your book aswell bud.

Connection between logarithms and changing numeral systesms.

I just found out recently that converting between number systems (i.e. decimal to binary) uses successive multiplications or divisions depending on the digit placement. Then it dawned upon me, so is this why logarithms and modulizing number systems are interesting in Number theory. I always wondered why they make computer engineers study number theory.

Its a pretty interesting topic to dive into.

I dont have any links really have links on this one. Mayber check out the history of logarithms and see the correlation.

I would look at the translated version of "Mirifici Logarithmorum Canonis Descriptio," and look at what mods do.

For instance, using the integer number system and modulizing it by 2, I build the set of number which could be represented as binary numbers.
