Moderately Difficult Math Problem (solve if you're smart enough).

What?
the fourth dimension in the sense of physics as expressed in Quantum Field Theory

A plane of existence that has one extra dimension. Hence, extra-dimensional.

In quantum field theory it's a bit different because the geometry is defined by various relations in nature. That said quantum field theory works with four dimensions—three spatial and one temporal—all in a mess of undetermined parameters and a lack of generalization.

Some of the things described about the 4thD seem unreal, I think it's pretty awesome.

The notion of learning how to work with this mathematically does intrigue me.

How to work with dimensional projections? That's basic linear algebra.

You ignorant people get impressed by the simplest of things.

I'm not ignorant, I'm just no where near linear algebra. Linear algebra is MAT 201, I'm way back in college algebra at MAT 121.

My three first courses were: [list][*]Single Variable Analysis [*]Linear Algebra and Geometry [*]The Physics Around Us[/list]
These courses were held simultaneously over the first period (seven weeks) in our program.

So we jumped straight from high school maths to Linear Algebra. Which leads me to wonder whether or not you were even taught multiplication in high school.

I almost dropped out of high school. The minimum requirements was rudimentary algebra. As in below MAT 096.

However, I have a friend who's graduating this year, a senior in high school, who's exactly where you were as far as math, suffice to say he has a perfect GPA, he also won the State Wrestling Tournament and placed 2nd or 3rd in a Nationally Ranked Tournament when not going ballistic on his education. He has scholarship offerings into so many universities.

I just decided not to go to school and instead to **** around. I'm not the best one for you to compare your education with.

Makes sense.

So why the change of heart? Why not continue to **** around?

Because some things never change....but some things do.

Idk, the notion of being mediocre no longer appeals to me. My eyes have been opened to the wonders of science.

Only the brightest will have a place in the future.

Well if you ever need help with either math, physics, or programming, sent me a personal message.

I wouldn't give you the satisfaction of seeing how far behind you I am now.

I tested out of all algebra and geometry related classes. I didn't have to take those in college.* My Freshman year, we did cryptography for our "math". We not only had to select all values and encrypt and decrypt a set using the Merkle-Hellman knapsack cryptosystem, we had to write a program that would do the same....all of it manually (by hand...and on the programming, no shortcuts: we had to write the entire algorithms). Certainly, it was an NP-Complete, but it certainly felt hard. ho ho ho!

*That was my way of saying that some ignorant people are burdened with the simplist of things when they first go to college...because you said this "You ignorant people get impressed by the simplest of things." 😮‍💨

Cryptography falls under Linear Algebra too. Nice try though.

Uhhh....very little of it does.

Here is some of the math used in it (note: none of it listed is "Linear Algebra"😉:

Abstract Algebra
Combinatorics
Algebraic Geometry
Discrete Math
Calculus
Statistics

Nice try, though...but you have quite a bit to learn if you think Cryptography falls under "linear algebra." That would be like saying all colored pencils are blue.

The underlined are part of Linear Algebra as well.

You have that backwards.

Linear Algebra is part of those groups. All of them.

I don't have it backwards, they go both ways.

Not all abstract algebra is linear algebra, and not all linear algebra is abstract algebra.

But you're right in that linear algebra is applied in statistics as well—in fact I covered an example earlier today in Dolos' thread—I was more focused on the first course we had in it which didn't cover statistics.
