I'm someone studying Physics first year but I noticed something, it's that I just cannot follow what the teachers say but I understand their notes much faster which they put online. I'm considering not going to lectures anymore except if I have related questions but instead spend that time reading the notes myself. This is especially true for analysis and algebra, I actually understand the physics teacher.
What do you think /sci/ ?
I did this for my Differential Equations and Linear algebra courses. Both because the teachers were rather slow and because I enjoyed getting lost with my girlfriend.
Just do whatever works for you. Just avoid being the fucker that never shows up to class and asks about stuff that was covered a week ago.

>1st year, analysis & algebra
Germany or Czech Republic?
Also, yes, it is much better to just study the notes if the lecturer is some autismal sperg that can't properly communicate the ideas and just occasionally give you additional insight. Only attend lectures if you don't understand the material from the notes or it doesn't make that much sense.

Swiss. But thanks anyway, I'm just curious to see if that is a method that works as that is my first year and I don't want to fail lel.
I used to dream about math whenever I'd study the day before, I'd literally dream about how exponential functions are constructed, drawn, differentiated, I'd just see things unfold from the perspective of the math itself.
Has anyone else experienced anything similar, or am I just autistic?
>>8464205
>am I just autistic?
That is a gift, not autism.
I remember once in highschool I had a dream I was solving a trigonometric identity problem but thats the only time it ever happened for me
The only thing you should be dreaming of is life in communist russia with your waifu
Material science is awesome. Why isn't there more solids chemistry on this board?
I have a feeling most of you niggers are math bullshit artists.
>>8467636
chemistry is biology tier buddy
so fucking boring
>>8467636
You happen to be in gradschool?
>>8467660
we covered this in freshman year in mechanical engineering.
So I'm sitting at work and my coworker and I were having some argument about whether investing in space exploration is worth it.
What is /sci/'s take on this and why? Please discuss this. I'd like to know all the arguments and counterarguments and counter-counterarguments in length.
>The context of this question: My coworker and I were at work and the news that basically said "the new US president is going to neglect space exploration programs and everything related" came on, and I couldn't find any convincing arguments on the spot to sway my coworker from his position that "there is no practical point to space exploration right now and there are better things to focus on and invest in."
If possible I'd like to know what the most direct and immediate influences of the space exploration programs (and things similarly related) are; as well as the most practical effects of neglecting them in the short-term as well as long-term scenarios.
As such, any detailed analyses and practical explanations are more welcomed than a general answer.
To be more specific, what I am looking for in particular is arguments based on the most practical and immediate influences to date of space exploration programs. Listing products that these programs directly or indirectly brought is is a good place to start for the argument (or counter argument depending on which side you're taking). For example, cell signals, artificial limbs, better highway safety, chemical detection, firefighter gear, solar energy, water purification, better software, etc. are all products brought about by these programs; but even those are not immediately practical enough. The more recent and detailed examples there are, the more convincing the argument is going to be.

Investing in space travel now increases our ability to space travel later.
Earth is also the cradle of humanity, and we can't stay in here forever.
>>8467556
Obvious counter argument: That is an extremely long term investment and therefore not exactly necessary at this point, and there are plenty of other things that need our attention and resources.
OP here and I'm taking the side of investment, but even I can see that much of a counter argument. Are you even trying? /b/ did better with this question.
You could maybe argue the case that the time to start increasing measures to explore space is a good thing to do now, just because of how popular space and technology currently is
this is our main political failing
>>8467473
No, there's plenty of space but we still have to lower the population so poverty ends
And also you don't want the world become the main cities of china everywhere with no space left
Just search "chinese overpopulation"
>>8467473
and who's going to pay for it? how much will it cost? who can afford it?
>>8467576
Programs that give housing to the homeless save taxpayers money in the long run, fairly certain in most localities shitty taxpayer funded 3 room homes or apartments run far less than the cost of year long incarceration.

should women be astronauts?
Sure
Why not
>>8465741
>physically weaker
>can get pregnant and become a liability
>menstrual cycle
>mentally inferior
>>8465752
Well given the past and existing female astronauts they seemed to perform well enough
>yfw they managed to become an astronaut whole you're just a shitposter on 4chan
what is (x+1)/(x-i), my Chinese professor has limited teaching skills and i cant find a way to solve it online. I was hoping you guys could possibly help
>pic unrealated
also, just to emphasize, the work is required to be solved through synthetic division.
Try multiplying by (x+I)/(x+I)
>>8467207
What do you not get?
You have a polynomial ring.
You have an algorithm that works for all polynomial rings.
What room is there for confusion?
1 + (1+i)/(x-1)
I want to pursue something worthwhile.
What's the hardest math?
Ex: algebraic Topology.
Some theorems are difficult to grasp because you have to keep a lot of info in your working memory. Linear algebra on the other hand is the easiest subject I can think of.
I don't get why you equate hard to intuit with worthwhile?
what are your goals?
>>8467155
Algebraic topology is a prerequisite for most research, but it isn't a research field.
It's like saying that you're researching trigonometry.
>>8467157
Not hard to intuit, hard to understand. There are honestly difficult subjects. If I'm going to continue doing math, at least I want to do something smug and to be looked with awe by other mathematicians.
Why hasn't a revolution started against people who are preventing others from solving the problem of climate change? Why aren't people angry at the thought of their children and grand-children inheriting broken planet? Why are people so complacent about this? This isn't an issue of the right versus the left, this is a matter of life and death.
dog have you never read darwin's 'evolution'? we and our children will just adapt to the higher co2 levels
>>8467148
Climate change is a long and slow process, and there's always something immediate to distract people.
Plus, fossil fuel companies have some of the best PR out there, and they've done a very good job of making talking about AGW political suicide.
>>8467148
Because it stinks of a new age religion and we already have enough problems with the Abrahamics right now. The climate always be changing, always will and in fact more ice ages are what real science points to, the historical geological record not fancy UN computer simulations. We should be celebrating any temporary warming because the big freeze will be back no question about it.

Hey guys, Idk why, but since I was 12-13, I wasn't involved in any kind of social activities. To me it seems like a waste of time, and I am pretty much bored of just beeing outside chilling with some people. Even with grils. I feel like everybody around me is silly, and I have to act silly aswell, to be in any kind of conversation. I don't want to talk to anybody, but then I feel the need to, because otherwise I am getting depressed.I have never done an IQ test, but I am pretty sure mine is something like 105-110. Should I still try to find friends who tend to have an IQ about 130? I thought they could be more interesting, and I would not need to act, to be in conversation. Even though they would probably need to
>>8466991
Being socially inept doesn't automatically mean you are above average intelligence.
The first to question you need to ask yourself is: Why are you friend with them if you do not enjoy their presence?
>>8466997
I agree. I estimate it to be something like that, because of a test I did in high school. I became second from 25+ students, and the best achieved 5 points more than I did. And her IQ is above 130
i Know this may be easy for most of you but i am still learning. can someone walk me through how to solve this?
y = x - w.
Look up law of cosines
>>8466908
will do.
Alright. So I have a ok understanding of law of cosines now can you explain to me how you got y=x-w.
>second time taking Calc I
>go to every lecture, take detailed notes, go to tutoring, study and do all the practice problems I can
>failing again, derivatives on test are obnoxious, like quotients with product rule inside product rule on top with chain rule on bottom with weird, long factored form and I get mixed up and confused when simplifying
>failing for the second time
Am I too dumb for STEM? Are there any /sci/ libarts degrees? I have no interests other than science, but I cannot into math.
Practice more.
should have re-taken precalc instead.
>>8466814
OP here, I got an A in precalc and had an A in this class until we got to optimization and related rates. I don't understand how to set these things up and the huge derivatives make solving for max/min/ inflection points impossible.
