Can we ban GPA threads? Does this happen every semester? And do you offending freshmen have any self respect?

I understand the desire to describe concepts with a single letter. Yes, it is nice and elegant... but doesn't anyone else think this is a tad ridiculous?

Hey /sci/, I need some help with quadratics. Specifically converting a Quadratic formula from Standard form to Vertex from by completing the square. My teacher cant explain things well and our shitty book doesnt explain in the examples, it just does a problem. So I thought you folks could do a better job. Ill just use a question from my HW because I cant make up one that will work y=2x^2+6x-3 y=x^2+3x-1.5 1.5=x^2+3x+2.25 3.75=x^2+3x+2.25 0=x^2+3x-1.5 (x +_)(x -_) Thats as far as I got. I feel like I did something wrong along the way.

Hey /sci/ These types of problems have always confused me. For a, at 1, g is at 4 and f is at 6. If I multiply them together and derive then I get 0? This makes no sense at all so I must be doing everything completely wrong.

My civil engineering college will start on january 2013 and i plan to spend the next 5 years studying it, and i'm pretty anxious about it. Could you guys give me some advice of how to deal with studies, stress, or any hard situation i might have to deal with. Also, i'm curretly on vacation. is there anything i should do on my free time that could help me with the first semester?

Any willing to help with a problem? Find the solutions to this equation: 0=(x-2)2^(x-1)

I have a question for one of you math kids. Pic related. The blue line is y = x for 4 pies. The red line is y = sine x for 4 pies, except I rotated it in photoshop 45 degrees, and stretched it 141.42 percent. How do I say the red line in math?

Space Exploration

How long until we send out space craft with really fancy 3D printers in them so that as technology advances on Earth we simply uploads commands to the spacecraft so that they make repair and upgrades to themselves?

I want an MRI of my brain for shits and giggles. If I participate in an fMRI study at a university, will they let me take the file(s) home on a drive? I know there's NIH/NSF software for viewing them. Picture somewhat related.

Well hello there /sci/... It's been awhile since I've posted, and I finally have some down time, allowing me to post again. Anyways.... Would any of you fine, aspiring scientists need any textbooks for your upcoming semester? If any of you remember my thread earlier this year, you know I'll do my best to deliver your request.

So something weird is going on.. On the dutch webSDR reciever it seems 'words' have appeared into the frequencies. I'm not sure what causes this or how its possible, but the picture you see is what popped up. I ran the image through some filters and flipped it and came up with a slightly more clear image on the word which I will post below. But does anyone have any idea?

Intro to science/rational thought

I need to get a gift for a 13 year old girl - any good ideas? I sometimes wish I had been introduced to science at a younger age (the stuff in public school doesn't cut it), so I was hoping to find something that might spark some early scientific interest.

How would you find the fundamental frequency of a bridge? I know of two equations to do with fundamental frequency: f(n) =\frac{k}{m} and f(n) =\frac{1}{2\pi} \sqrt{\frac{k}{m}} But both of these equations are fixed at one end and have a mass at the other. So what if a beam was attached at both ends how would I make an equation for that?

Mother fucking Euler vs Mother fucking GAWUSS! No fan-boyism and no personal life comparisons (As Euler sucked Jesus' dick day and night and Gauss was the most arrogant Mathematician in history). Only compare their math achievements.

Hello /sci/. I'm a physics undergraduate student right now. I'm probably going to graduate with about a 3.3 GPA (out of 4). What are some possible things I can do after graduation? I know about grad school, but what jobs seek physics majors, and how hard are they to get?

Hi guys, I've recently decided that I want to pick up a second language. I am about to become a chemical engineer, and was curious as to what foreign (to a native English speaker) languages you, hopefully as engineers, come in contact with the most? I would assume Mandarin, but I could be wrong. I would like your input. Thank you very much!

What are the most important things you study in Mechanical Engineering? For Electrical, taking Circuit theory I, Circuit theory II, Electromagnetic theory, and a course on Diodes and Transistors is 80% as good as going through the whole curriculum. What are the most important courses for Mechanical?

Hey /sci/, Pre-med here. I was wondering if you guys have any advice on what to study for the MCAT. I just bought the Kaplan books.

Quadratic Equations

Math question to the smart /b/-fags. I sit here with a quadratic equation, but it doesn't have any reel solutions. I would realy like to learn how to find the complex roots of the equation, when the discriminant is negative. Here is my equation: 12*x-24-16*x^2 = 0 Does anyone have any smart way to do it, because my teacher at college hasn't got any idea how to do it.

How do I become smart?
