So Northrop Grumman just called me and asked me to re-email them my resume and transcript that is updated for this year because they want to interview me. But the fucking bitch I'm talking to is a worthless cunt. I attached the files like she asked in .pdf form. Apparently they can't download .pdfs or something from emails. Retarded ya? She tells me to use .ngpdf. I'm thinking WTF is this file extension? So I just put it in my dropbox and send her a link. Here is her reply: >Hi Stephen, I cannot access dropbox via NG network. Rename the extension of your document with .ngpdf (i.e. firstname_lastname_Resume.ngpdf) then send it to me. >Please send me your resume, prescreen and transcripts so I may submit you for consideration to my hiring manager. Seriously this shit could not be more dumb. She won't fucking tell me how to get the file with that file extension and google returned nothing valuable either. I'm considering not actually going through with applying to them if there company is so fucked up they cannot receive .pdfs or explain how to people how to get the file extension they want. Fuck I just want to rage.

What the fuck is variance used for?

Hey /sci/, I'm in a probability and statistics class up in Uni. Right now we're working with mean, variance, and standard distribution. I understand the idea of a mean just fine because I've been working with it pretty much all my fucking life. Roll a d6, mean value is 3.5, meaning in the long run if I roll billions and billions of dice, half will be above 3.5 and half will be below. I can also understand standard deviation to a point, it's the average distance for any of those points in the data set from the mean. So where 1 is 2.5 away from the mean, 2 is 1.5 and 3 is 0.5 (and in reverse order of the aforementioned for 4, 5, and 6), the average of those values is 1.5. Easy shit, I can see the usage for either... But all I know of variance is how to calculate it. What the gog damned fuck am I supposed to use it for though?

Geology

I'm starting university next fall, and originally planned on doing a chemistry major, with plans to go for a PhD since I'm too squeamish for med school and being in charge of research sounds way more interesting than being a lab monkey. However, it turns out the university I'm going to has a great school of earth sciences and after doing a little preliminary research, geology/geophysics sounds much cooler and more interesting than chemistry, but I haven't been able to find much detail on what students in these majors really study or do, and I'd like to know a little more. So does anyone have experience in a geology and/or geophysics program they'd like to share? Any information is appreciated, especially pertaining to what is actually studied and what the curriculum is like.

http://en.wikipedia.org/wiki/Ampere#Definition Why is the ampere defined as "the constant current that will produce an attractive force of 2 × 10–7 newton per meter of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one meter apart in a vacuum". What is the constant 2.7 * 10^-7 and why is it not defined as the flow of electrons equating to 1 coulomb per second?

"Using partial fractions and complete the square..." I can do both partial fractions and completeing the square but I dont know how to combine the two to solve pic related. This is part of a Laplace initial value problem Any pointers / which direction should I start it in?

I wish I could tell you what it is like. To feel like you're truly working towards something good. To think that you will make a difference, not only in your eyes but in the eyes of the world. But the world isn't watching. It never is. Instead we're locked in damp basements working grueling hours on something which in all likelihood will be insignificant and ignored by our peers. Because that is the harsh reality that comes with doing science. For years you will feel like what you do makes no difference. The stress and the pressure slowly building up to a point where you feel like you just can't take it anymore, only to be taken away temporarily by some minor achievement like getting another degree, or a publication in that slightly higher up journal you've been hoping for. But it always returns. That lingering sense of insignificance. The realization that everything you do, however brilliant it may seem to your close or even distant colleagues, is incomparable to things which have been done before you. Even if you make it you will feel like it was all just luck. That you happened to be in the right place at the right time. That that tenured position wasn't really right for you, but you got it anyway, for no apparent reason. Years beyond, when you are widely regarded as an expert in your respective field you will still have that feeling. That you do not really know what you are doing. That it was all luck which brought you there. That you are an impostor, living the life of someone else. But this isn't true. You will not be an impostor. What you have been working on, however minor the problem may seem, has relevance. Everyone before you likely felt the same way. You cannot become great by trying to be great, but by wanting to do something with such a conviction that you become great in the process. Remember this in your years to come. It will comfort you.

Researching High Tc supercoductivity, can anyone explain what the order parameter is, the energy gap and how they are linked? I know for HTSC the order parameter has d-wave symmetry but don't really get how this correlates to k-space or the fermi surface...

Hey /sci, I asked /b for help but I have received none thus far. I need help with a c# programming assignment. I don't know anything about programming and I feel like it's being thrown at me all at once. This is the assignment: Create a Car class that has a constructor that accepts a Make and Model (e.g. Subaru BRZ, Toyota RAV4). Make these properties read-only. a static property that is the number of miles driven with a set and get a static property that is the number of gallons used with a set and get a static method that returns the miles per gallon computed using the two previous static properties a non-static method that returns the miles per gallon using the same two static properties In main, create two cars, add some miles driven and gallons used, print out the miles per gallon using each method. Why does each method return the same value? What do the static properties represent ? (Do they describe a property of a specific car or of the set of cars?) If anyone could help me complete this assignment I'd be more than likely to donate some money over steam, PayPal, etc.

Alright /sci/, in light of this: http://ehp.niehs.nih.gov/2012/10/developmental-fluoride-neurotoxicity-a-systematic-review-and-meta-analysis/ ...let's talk Fluoride I've always thought it was generally odd that it was put into water to "help our teeth" since you immediately swallow water and exposure of that sort wouldn't really make a huge difference in enamel health. But I've also never thought any of the shit that the tinfoil hats in the world spew about it either. So in light of this release by Harvard, why is this shit still in our water?

http://cms.springboard.gorillanation.com/previews/1441/video/660959/ Science punter here, can someone explain this to me please, /sci/? Is it some kind of reaction of salt with the nerves? Or does the thawing process cause the muscles to contract? Pic semi-related
