Browsing /b/ and found a pic with a troll OP but someone there claimed math graduate and after finding the obvious answer of (8/3)x+13 he proceeded to find the inverse function of F(g(x)). Here is the thread; >>>/b/481451187 Did he find the inverse correctly?

Extremely Basic Research Proposal

1 more posts in this thread. [Missing image file: 1368521555007.jpg]
Hello /sci/ Professor wants us to write a research proposal in one night, just a hypothesis basically, but he is setting us up for failure, he said he will point out whats wrong with each of them tomorrow. If I had a week I could make a damn near perfect one, but no. He is rather arrogant too. I wanted to do something with hydroponics and hydroponic gardening on a small scale. Variables I could test include the medium in which the plant would be some-what attached to, factors affecting pH, nutrients in the water, the water itself, air being pumped into the water (as in what is in the air), etc. but I have no idea what to do that is completely original (he says if my proposal has been researched before or a similar hypothesis has been made then he will throw out my paper). So I'm stumped and need help. Pls /sci/. Gibe knowladg plos.

Debate partner.

I know this isn't about any specific part of science and/or maths. But how would one go about acquiring a partner with whom to debate various topics with? All of my friends seem to be incapable of having a proper debate. So if anybody is interested, reply? pic unrelated.

im trying to solidify my "algebra" skill. How can i do so? Right now its average..but im having some problems with the big equations with multiple terms and division and simplifying and systems of equations. Just now i got stuck on an algebra step because i didnt realize if you have something like dividing the entire equation by x will remove x from the numerator of a fraction. little shit like that holds me back tl;dr where can i learn the "Rules" of algebra manipulation and simplifying?

Copenhagen Suborbitals

0 more posts in this thread. [Missing image file: sapphire.jpg]
Hey Science, How many people here have heard of Copenhagen Suborbitals? They're a nonprofit organization aiming towards launching a person into space on their own time, budget, manpower and machinery. I personally think they're doing great work, and I can't wait for the day people are building satellites and rockets out of their barns and garages. Rock on, spacepunk. Rock on.

I don't ever come to /sci/ and i'm not sure if you guys do anatomy based health science, but i'm looking for help if anyone is willing. I'm a PTA and i'm looking for information on How the body is effected physically and cognitively after a stroke based on what part or parts of the brain are effected. going further than just "oh its a left sided stroke so you'll have right sided hemiparesis" specific sections of the brain being effected leading to specific outcomes.

I don't really know where to put this but i guess this is the closest board related to minerals. so anyway this is a chunk i took from the rock where i live (iceland). I suspect its a meteor. the there are tons of crystals in the rock( many became loose and dropped off) and the land isn't old enough to produce so many crystals and its the only rock like this one that could be found near the area. the boulder it self is about 2m in length and i just took a chunk out of it. but the thing is I'm not an expert on this kind of stuff. and hopefully there are some out there who knows more about this than I. any information or input about this rock well appreciated

How common is it for scientists to falsify reports? Or skew results in favor of a particular outcome?

Is it possible to learn much from the MIT Open Courseware courses? I want to self-relearn Chemistry over the summer and attempt to CLEP out of Introductory Chemistry & Lab. I thought I did pretty well with Chemistry in high school, but then again, my teacher just gave out free As sometimes. I've tried doing Open Courseware with things such as Mandarin Chinese, but I can't figure out if there's not much material on the site or if I don't know how to use the website at all. Thoughts?

Hey /sci/, I was just looking for homemade alternatives to resolve, cause I'm poor and need to clean carpets before I move. One of the more popular results is Ammonia (windex, which has ammonium hydroxide) and Vinegar (acetic acid) Wouldn't those two cancel out and produce ammonium acetate (a salt) and water? Is there any difference between just using table salt and water or this? Do you think the ammonia salt would be any more useful than chlorine salt?
