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.

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

Prove that if S is an unbounded subset of R, then there exists a sequence (sn) such that sn in S for all n in N and (sn) does not converge to any real number.

Dear /sci/, I'm a high schooler trying to make a science fair project to enter into the county scifair. I'm trying to build a project that will let me prove that anybody can grow algae (I use Chlorella) in their yards and extract lipid content. Then refining that oil converting it into viable biofuel for small engines or even automobiles. I'm completely overwhelmed since there are so many options for each step of the process and I'm afraid of failing and wasting me and my partner's time and money. It seems like a simple concept but is actually quite tricky. Any tips if you've ever been in scifair would help. Thanks!

What the fuck is variance used for?

16 more posts in this thread. [Missing image file: fishassholes.jpg]
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?

Hey, I'm a 18 year old guy from Norway that's soon going into a two-year grade on technical college - nautic. My math skills have never been to good, so I thought I'd might learn some new maths. The math im getting on college is pretty hard, and I thought i should prepare myself a little. Do you reccomend any books or anything like that so I can study home etc

Mermaid found near Black Sea in Bulgaria Ancient skeleton of a mermaid before the Flood 8 millenniums ago was found near Sozopol Beach by Professor Dimitrov. The photo first appeared on the wall of a journalist Petar Genchev Facebook, but minutes after it is shared by dozens of others, impressed by the impressive growth of the former female fish. >explain this bullshit

Hi /sci/, I'm going into calc III, and I want to review the old stuff as well as get a look at what I'm getting into. I'm aware of khan academy, but I want to know if there are any other online free learning courses for math. Any experiences?

Science is (nearly) finished

36 more posts in this thread. [Missing image file: einstein.jpg]
In the latest Nature there's an article about how scientific genius is extinct - Einstein was the last genius. The argument is if you look at the current rate of scientific advance in the natural sciences, it has slowed down dramatically, and it takes larger teams of people and greater resources to make smaller and smaller incremental advances. There are no longer any lone geniuses revolutionizing a field of science in their spare time. The reason for this, it is argued, is not that Einstein was unique, but rather that we're nearly finished in the field of scientific discovery, there are simply no more scientific "revolutions" to be had. There are many discoveries to be made and much that remains unknown, to be sure, but these are minor details rather than fundamental laws like E=mc^2. An analogy can be found in sport - we are still breaking records at the Olympics, but by smaller and smaller increments every time. There are no longer Olympic-medal winning "all-round" athletes breaking records in multiple sports like Jim Thorpe or Carl Lewis. Everyone is highly specialized and shitloads of training and preparation involving teams of people goes into every millisecond of a record broken. What say you, /sci/? Do you agree with the Nature article, or do you believe that you will be the next lone genius like Einstein and bring about a scientific revolution?

"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?
