Why is linear algebra so damn boring?

45 more posts in this thread. [Missing image file: url.jpg]
How do you force yourself to work through mountains of boring mathematical shit when they're a prerequisite to more exciting topics? I'm trying to refine my scientific knowledge and I thought it would help to learn linear algebra. I knew it would be painful but I never expected this. I can barely stay focused. It's not like I'm not learning, it's just impossible to get into it and enjoy it on any level. Every inch I gain takes a monumental effort of personal discipline. I know for a fact that not all mathematics are like this. I actually enjoyed calculus to a degree. But linear algebra seems like the most frivolous axiomatic shit I've ever had the ordeal of studying. I'm sure some of you can /sci/entists can relate. How do you cope with this god-awful field? Or any topic you need to get through?

until now no one ever gave a decent answer to the question that I drew up for everyone interested in the subject. Just name calling people who do not have arguments for Hurts and depart. I do not care for these people. But I know that in the midst of so many good people have yes. And it is for them that I did this work. www.maog.com.br

So uh, got a math deal that is confronting me. Seems like it would be a decent word problem. I currently have one oscar fish in an aquarium. I would like to add another. Oscars are monomorphic so you cant tell males and females apart, and if you end up putting two males together they will fight to the death. If you put two females together you have a 90 percent chance of them successfully living together. If you put a male and a female together you have a 75 percent chance of them successfully living together. I would greatly appreciate it if someone could tell me what my odds are for having a successful two oscar tank if i go out and buy another one today.

Why is CS bad?

OK, without having to resort solely to unoriginal images as arguments or just pompus trolling, justifiably explain to me why study for a degree in Computer Science is bad. For me personally, I am focusing on one and a potential math degree as well.

Just saw the most compelling video for the unifying force of nature I've ever seen in my entire life. Holy shit, what are your thoughts on Primer Fields and the Electric Universe Theory? Watch this before you weigh in, please. These are actually very well put together with lots of experimentation. This is actually 10 minutes in to Part 2 on a three part series put together by this guy. It was originally supposed to be an 8 part series, but he has been busy for quite some time and has yet to upload any more material. Still, it is very good. http://www.youtube.com/watch?v=2NogyJ0k8Kw&feature=player_detailpage&t=600 Picture very much related, it is his belief that bowl-shaped magnetic fields are what shape the universe.

Is it possible that dark matter is just the sum of gravitational forces of matter outside the observable universe acting on the observable universe? This is probably a stupid question. I apologize in advance, but i've never seen this idea brought up before.

Is the human race doomed for extinction? Is there any answer with a level of certainty to this question?

I know this is basic as fuck, bust i just can't figure it out! Help me /sci! I have to calculate the angels in a triangle with use of vector. The coordinates is A(5,8), B(8,13) and C(12,8). Theese are my calculations http://imgur.com/7ihNghz but its clear to see B and C is wrong...

Why is there no degree with biophysics like there is biochem? what do I need to take to get into biophysics?

Could Australia construct a series of seawater channels surrounded by mangrove tress and slowly terraform the desert? We often talk about terraforming mars but Australia seems like a better place to start.

I'm trying to prove that n|(nCr) (for all r) if and only if n is prime. (1<=r<=n-1) Now proving that if n is prime then n|(nCr) is pretty easy, but how would you go about proving that n|(nCr) only if p is prime? Could you show that if n is not prime, then there exists an r such than n does not divide (nCr)?

Didn't see a Medicine board so I figured this was the best place. My mom came home today and said she has to go in for a CAT scan tomorrow, because she has an "abnormality on an artery" in her brain. What could that be?

Why isn't there a proper cure for baldness yet /sci/ that I can just go and buy in a pharmacy. It's 2013. It shouldn't have to be this way.

Are emotions inherently irrational or what?

Diagnosis time /sci/. Itchy rash being the only symptom aside from diarrhea which is most likely unrelated. Starting on the chest and neck, the rash has spread onto the lower half of the face along with over the entire torso and slightly down, starting on the extremities. Pic related. Aside from the rash, there are no other typical symptoms of meningitis (Not the right kind of rash), measles, etc. Chlorphenamine (antihistamines) has been administered with no effect.

Any other botany/growers /sci/? I just fucking love plants, live in hot as fuck So-Cal... can grow just about year round although it gets too hot in the late summer. Step out half plants look like they're just about to go, FUCK!!! Quickly spray with some cool water move out of the sun, go back to looking great right before my eyes. What's /sci/ growing?
