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?

How do I determine if 'nofap' is pseudoscience?

I'm only just entering undergrad, and I stumbled across this group that gives off the vibe of a cult called 'nofap.' Their homebase is a section of reddit called r/nofap, and they claim things like "if you don't fap for about 90 days, your brain will reboot itself to its normal state" "by not fapping for an extended period of time, I notice girls are more attracted to me, and I get boners more often, and I actually grew to like them" "i have more energy due to higher testosterone, and I felt the effects of nofap even before I found out about it" Of course, these are all paraphrisations, but I want to know what /sci/ thinks. There must be trained physiologists here, right? http://www.reddit.com/r/NoFap/ http://yourbrainonporn.com/your-brain-on-porn-series https://www.youtube.com/watch?v=wSF82AwSDiU

What is the hard science behind hypersleep chambers, if there is any? See em all the time in teh movies, but is there any legitimacy to them? even theoretically?

so they finally proved that DMT is in fact produced by the pineal gland. how wrong do you feel now?

So I did what everyone kept saying was a good idea. I got a science degree. I have always been interested in water and water issues and I have a real fondness for geology. I got my degree in geological sciences with the hydrogeology option. I could have gone with the minerals management option, or the Oil and Gas exploration option. The Hydrogeology option requires far more math including 4 semesters of calculus and differential equations but it is what I wanted to do and everyone said it was a good field. Now I have graduated and every damned entry level job asked for 1-3 years experience and still declares it is entry level. I have sent out more than 100 resumes and applications and not a single e-mail back. This is getting frustrating. I just want a job in environmental science dealing with contaminate plumes. I don't think that's asking a lot. We have lots of them in this country.

8 more posts in this thread. [Missing image file: oscar.jpg]
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.

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.

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?

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
