>"This degree provides graduates with a strong foundation in analytical and communication skills, which are of great value in all walks of life and career paths"

Well, communication is of great value in all walks of life and career paths.

Now, here's the difference. Is this a STEM degree with a short 1 or 2 semester writing/communication component, or is it a degree all about communication?

If it is the second one then indeed, the degree isn't worth shit.

Well being a sperg master won't get you anywhere, fag.

Kek. It's always the communication type majors that bitch about student debt because they can't get a job.

No

>What are the implications?

For the average person, probably not that much. Once they actually work (and can do prime factorisation) then RSA will become obsolete.

It supposedly uses quantum mechanics to be much more powerful. They said it solves certain problems 100 million times faster than a regular supercomputer.

what does /sci/ think of this?

http://www.sciencedaily.com/releases/2013/01/130104143516.htm

Old article, but it states that a laboratory has managed to create a gas with a temperature in "negative Kelvin".

This means below 0 Kelvin, which makes no sense to me because I thought temperature was measured according to particle movement and 0 Kelvin means no movement... the article doesn't do much justice in explaining the concept very well.

Negative Absolute Temps aren't a new concept. They are actually hotter than positive temps. This might seem paradoxical, but it makes sense scientifically.

Anons, I need advice. I am the 1% of women in my CS course and somehow I've ended up with this guy as my lab partner. My problem is that he's waay too ahead, not just me but he's on a scholarship and have a hell good amount of experience in the industry etc. What's worse is that I myself am basically the complete opposite - I'm grinding my ass off trying get above the curve (went to a girl's school, no computing courses offered before uni, had little preparation as i changed to CS from another course at the very last moment etc). Being with him is not helping at all - I am a burden 100% of the time and I don't know what to do. What would you do????

How about you start with "how can I help?"

At least you show up to lab. That alone makes you more helpful than 90% of the lab partners i've been stuck with in the past.
>>
>>7842908
I would blog on /sci/ about it, making sure that they know I'm i grill btw xp
>>
Ask him within the scope of your abilities, (explain) what you can do to lighten the burden of whatever projects you must complete. Also, everything is a paradigm into something else, from what is standard in the course of industry and work, to the fickle moments of individual imagination. Through a topological body, question yourself on how things are connected.

Honestly, I've got mixed feelings about them, I'm 1000 issues in and I'm still unsure if I've learned anything new about the post-grad life, it probably says something that I've yet to save any particular strips for future reference. Did /sci/ learn anything from them? At the very least, they're entertaining, but are they even accurate?

Also, does anyone have the second book? The author never put Mike's thesis defence online.

>>7842852
Mostly accurate except for the obvious exaggerations.

I tried to read all the comics in one sitting once. Failed. It gets really boring when he starts doing his trips talking to grad-students who dumbed down their research is a step up from pop-sci, but not as interesting as reading the front page of Nature.

I'd also like to see Mike's thesis defence, I'm considering just buying the book, but I'm kind of mad that the author took grad-school spots at top schools and a tenure track job only to quit and write comics full time so I'm boycotting his book.

>t gets really boring when he starts doing his trips talking to grad-students who dumbed down their research
You mean the tales from the road thing? I'm planning to read all of them in one sitting, the text on them is too fucking small for me to bother to put in that much focus when I'm reading the other comics for procrastination purposes.

Could you jump out of a helicopter last second before it crashes and be live?
11 posts and 2 images submitted.
>>
No more live than if you stayed inside. Autorotation lets helicopters fall quite gracefully to the ground, provided the main rotor still rotates freely and there's an engine fault and not a "huge explosion to the rotor" fault.

They're death traps, but not for the reasons you think.

they actually were worried that the nuclear reaction would chain with the hydrogen in the atmosphere and that they were going to catch the entire worlds air on fire and kill everyone.

I have a problem. I've been playing with ferrofluid, trying to make a display like pic related, but something weird happened. I filled a glass jar with 70% isopropyl alcohol (I read this would keep the ferrofluid from staining the glass), then added several drops of the ferrofluid. It worked perfectly at first, save for the isopropyl alcohol taking on a slight brown tinge. The ferrofluid behaved as you'd expect initially, but when I checked on the display a few weeks later, the ferrofluid had hardened into solid chunks of magnetite. The display was not in a magnetic field and the container was sealed. My chemistry is a bit rusty, but I think the isopropanol reacted with the carrier fluid in the ferrofluid, but I have no idea what or how. Help me understand, /sci/borgs.

The carrier fluid is described as a "light hydrocarbon" in the MSDS, which most sources seem to interpret as mineral oil. The only list of light hydrocarbons I could find contained gases, so oil might be a good bet. I don't know what surfactant they used.
>>
>>7842456
Carrier fluid is oleic acid, OP shoulda just used water
>>
This is a guess ok so dont diss me for it.
You are, at a basic level making a battery by adding the alchohol. Thus there is anodic/cathodic reactions occuring even between minute particles. For me, that brown tinting is a classic sign of battery corrosion, its an indicator of same in electolyte. As I say, thats my SUGGESTION for it - i am no chemist. Dont shout at me !

are these fields separate from each other?

>calculus
>linear algebra
>differential equations
>analysis

meaning, do you not need one for the other? are they all independent pathways?
18 posts and 1 images submitted.
>>
>>7842190
calculus and differential equations preceded analysis. Analysis is a more rigorous "version" of calculus and other theories(complex, functional anaylsis) and is consider more fundamental while calculus is more about application and function.

Linear Algebra is quite a different subject but has applications within differential equations
>>
>>7842190
>>7842193
Oh, and you usually take calc first, then diffy Qs or linear algebra after your 2nd semester of calc. If you want to take a real analysis course you need an introduction to proofs. There is also sometimes a more advance differential equations course aimed for mathematicians instead of engineers/scientist witch requires knowledge of proofs and linear algebra as well
>>
>>7842193
i was told that in order to study differential equations you needed to know functional analysis. is there any weight to this?
