Many will not have much emotional reaction to this slow USA holiday headline, but the imagery is so definitive, and so important for the small amount of data that was captured and transmitted, that I post this thread for the few who feel an attachment to this little lander, and the new knowledge that she is not lost to the mission.

Here is how Philae has been oriented under the rock awning.

Man that's pretty damn cool actually, good for them.
So is Philae completely dead?
Is time travel compatible with determinism?
time travelling is a sci-fi concept and determinism is a philosophical concept
tell me why you posted this on /sci/
Yes.

Time travel is just changing your location in an infinite multiverse of every possible scenario.
Hi guys. Entering my last year of a 4 year Mathematics degree. Need to take real analysis, complex analysis, and abstract algebra. I already bought:
>understanding analysis by abbot
I have some time to prepare before hand. Looking for tips and specifically book recommendations.
Thanks In advance.

What kind of meme is this?

Pushed all of the hardest classes back so I only have to take 2 math classes one semester and 1 the last. Double majoring in business.
I'll start with basic geometry...
Show that the curves y=x^4 - 2 and y=kx^2 intersect for all values of k
Start by setting them equal, [math]x^4 -2=kx^2[/math]. Then, [math]x^4 -kx^2 -2=0[/math], but setting [math]t=x^2[/math] gives [math]t^2 -kt -2=0[/math]. Now, the determinant is [math]D=(-k)^2 -4*1*(-2)=k^2 +8>0[/math] no matter what the [math]k[/math] is.
>>8301200
y1-y2 = x^4-kx^2-2
at x=0 it's negative
as x⇢±∞ it's positive since x^4 dominates
>>8301211
Not sufficient for a proof yet. One also needs to show that the solutions in x^2 themselves have real solutions.
That is, we need to show that there is at least one solution in x^2 to the equation [math]x^4 - kx^2 - 2 = 0 [/math] that is a positive real (so that x^2 = (that) has a solution).
When using the quadratic formula, we get:
[math]x^2_{1,2} = \frac{k \pm \sqrt{k^2 + 8}}{2} [/math]
Taking one solution:
[math]x^2_1 = \frac{k + \sqrt{k^2 + 8}}{2} > \frac{k + |k|}{2} \geq 0 [/math]
This completes the proof
Why do people struggle with math, specifically trigonometry and calculus? It's really not that complicated if you do a lot of exercises. Plus, the compatibility with physics is tremendous. I wouldn't mind so much if they weren't so deliberate about it
>lol i really suck at math
Why is this socially acceptable? To spout such a when you're half way through algebra says a lot about you.
>>8322983
Most of people's exposure to math is in highschool, which, frankly kills any possibility of looking at math as something cool and exciting, but rather turns it into mind numbing, seemingly meaningless exercises with no context or reasoning as to why something is the way it is.
>>8322983
>Why do people struggle with computers

>Why do people struggle with problem solving
Because the jewz filled the media with anti-intellectualism

Idk but as a HS math teacher I get tired of hearing it. Anyone can do well in math. Most are just lazy and are only interested in correct answers (passing the class) rather than conceptual understanding.
I am 18 and am currently in school for physics and astronomy. I am also schizophrenic. Anyone else here with mental illness? How does it effect your education?
Depressive here. Finished with a red degree whatever that's called in your american language, and now i have an eye condition where i can't read properly so i never achieve anything ever again (^:
Depressed, autistic tendencies, severely repressed anger management issues. General failure at life. Trying to work my way up as a code monkey so I can pay for it when I go back to college.
When I fuck up my dreams and never manage to prove myself, plan B is to produce sci-fi content which will somehow motivate kids to go into science.
I hear cyberpunk stuff can get people to go into robotics and AI.
This winter I won't have internet and will have minimal obligations and human interaction. I'm looking for textbook recommendations on a number of things.
-Physics
-Algebra
-Geometry
-Calculus
-Electrical engineering / (AC) circuit design
-Modern Material science and fabrication techniques
-Human anatomy, general physiology, and biochemistry (more or less pre-med material)
-Ecology
I'm aware of the sticky. I'm just curious about some more personal accounts. I already have a patchwork knowledge of most of these topics and their underpinnings, but severe deficits in mathematics specifically. Time I dealt with that overhead.
you won't be studying that all day just because you won't have internet during one season (one of the shorter ones).
here's my recommendation:
Problems in General Physics by Irodov
>>8321620
I probably will though, aside from part of wednesdays and thursdays. I've done it before, and perhaps I can return (but not regress) and do it again. Don't have a social life, etc, and live in a rural area.
>Problems in General Physics by Irodov
Looking into this, thanks.
If I had the time I would study topology cuz it looks interesting af. But practically you should study programming languages like python or c. One step below that would be electronics projects
Haven't made one of these in a while.
ITT you tell me why this can't be done.

Are you implying that America has always been a stupid country?
Hope you are kidding. 90% of the inventions since 1900 came from America.

>90% of the inventions since 1900 came from America.
Lol, that's not even remotely true. Europe alone files a lot more patents than the US each year.
I'm in college pre-Calc and want to impress my professor by asking a question about inter-universal teichmüller theory in class. What should I ask, /sci/?
>>8315336
"How can I cope with my autism"
You impress your professor by being a good student, not asking some gay shit that is beyond the scope of the class.
>>8315336
If you're a female, you can impress him by gaping your asshole and sticking a large gummy worm in there.
post women and their achievements you unironically respect
starting with the obvious
>Marie Curie
>nobel prizes in physics and chemistry
she might just be the most decorated female in science
>She died of radiation
Good job """discovering""" the radioactive properties LMAO
>>8321248
wew that was short lads
>>8321248
Omg YES!!
Let's start Marie Curie and her husband, and...well...
let's face it /sci/, man was never meant to explore the universe due to the massive distances between everything.
>>8317623

it is true, we must create a new form of life, robust and immortal like our machines yet with brains like our own to ensure they are sapient like us

Exactly, which is that money should go towards helping developing nations.
>became a dermatologist
>got to skip all of the meme college major/career charts
>will make ~$340,000 this year working ~9:00AM-5:00PM Mon-Fri
I do science and math every day, and people appreciate me. My skin is like porcelain, and my job is extremely cushy. I took physics for my undergrad, by the way. Have fun making $75,000 per year doing menial bullshit greedy engineering faggots lol. just wanted to add that.
If you want to go into medicine, it will be the best choice you ever made, by far.

Congrats on your career choice op I don't want to work that hard

Nah, sorry, people are disgusting. I don't want to touch them my entire life, especially old people.
Is anyone here interested in chaos theory? Let's discuss it.
Mind = blown. Just realized that's supposed to be a butterfly. Chaos theory is prity tricky opie.

Please contribute to discussion in a constructive manner.
Does P=NP
No, we're not doing this thread today. Fuck off.
What if P actually equaled 0 this whole time? I bet the computer scientists would feel pretty silly.
That would be pretty funny.
