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?

Ask a phd candidate in aerospace engineering anything.

It's been a while, ask me anything. My research is in aerodynamics, computational fluid dynamics, and numerical mathematics. I don't know much about space programs beyond the news and undergrad education in relevant technology.

Tell me /sci/ without any emotional bias: Which degrees are shit tier Which degrees are god tier And I know that mathematics and science knowledge are ALWAYS god tier, which surprises me to some extent. For example, I recently learned econ majors are not doing so well in today's market, I always thought that economics required a broad understanding of mathematics, mainly game theory, but recently learned that is not the case. Medical majors also do not require that much math, which is why more engineering BS's are getting into medical schools these days then pre-med majors. They do better on the MCATs

Just ordered some modafinil. I've been using piracetam + choline for a while now with good results but am keen to step it up a notch. What's everyone's experience modafinil?

Is the double experiment bullshit, like the rest of the quantum ? Picture very related

integral help

Hello, can anyone help me integrate this expression? This integral is part of a larger one involving partial fraction decomp, and this is one its parts. x / (x^2 - 4x + 6)^2 I'm tripped up by this squared quadratic. U sub doesn't seem to work, nor does trig sub.

Hi /sci/ prospective college student here. I just finished High School in my country and I don't really know where to go. Most of my friends are going to Seattle for some reason. Assuming I can go to mostly anywhere where do you guys think I should go? I have an uncle living near Toulouse but I don't know any bit of French. I'm interested in Physics but my parents are against me taking it so...more into MechEng I guess.

"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?
