If you're planning on taking a masters and a phd in the future, just how important is to have the highest grades during your bsc?
Just important enough to get into the program
but it is a predictor of future success
was talking with a friend who said that some of the teachers "preferred" a student who struggled but in the end passed, to someone who passed everything without problem, so that just got me thinking
some professors/lecturers have gone so far as to say that if youre not really prepared, dont take stupid risks, and just blow off the exam, and wait for the "re exam"
>>7980263
Why exactly do they supposedly prefer that?
Is school really worth it now that 5 year olds can access lectures on any topic from some of the best colleges in the world + basically any textbook worth using, all from home?
Yes, because we know you're never going to do the actual work if professor man doesn't tell you to do it.
College degrees are just as much about proving you know how to work as they are about proving you know stuff.

Actually I meant more highschool and to a lesser extent grade/middle school as well.
Should I be taking fish oil?
Will it make my brain work better?
>>7979791
Modafinil will make your brain work better.
>>7979800
I dunno man. I tried it for a week straight and it took away my feelings. I was like an emotionless robot or something. Also it made my dick extra flaccid. I didn't know that was possible, but it happened. Never again.

Yare yare daze...
>>7982016
Bet you think you cool.
>>7982030
No, I don't think I'm cool.
I think that I still don't fucking know the answer.
It will be years before I take a real analysis class so this will haunt me for a fucking long time.
I thought getting a PhD meant you were a genius.
>>7982035
Honestly most professors once getting their job tend to not remember anything not related to their specific field as they have no reason to. Hell most PhD students do the same shit.
Post 'em now sweet /sci/!
>>7981288
Nobody fails on /sci/. If they did, they won't admit it. Nobody wants to look like a brainlet.
>>7981290
>actually failing a class
>not just withdrawing or dropping
how fuckin' dumb do you gotta be m8?
>>7981290
I failed thermodynamics. Shit's bananas.
Hey /sci/, could any of you fine minds point a fellow anon in the right direction with how to solve this kind of kinetics problem?
>>7978066
>kinetics
Also, what the fuck do you mean by visible mass at the point of impact? What the actual fuck?
>>7978089
I think he means how much momentum is transferred to the struck object. Not sure how to work. Really we would need to know the properties of this "immovable object" though. Hopefully it's rubber or something.
>>7978093
If the object is by definition immovable, then no momentum can be transferred to it.
What programming language should I learn in order to be employable
>>7981067
C++14
C#
I need your help /sci/ my wife is trying to do chemistry and is banging her head against some of these equations and is now in the bathroom in tears because she cannot work it out. I was hoping some of you could help me find the answers. I'm not a smart guy and the work she is doing even though it's just Chem 101 is way over my head so any help you can offer would be greatly appriciated. I will post the question followed by the pages referenced in the question. I need the two empty spaces and i also think the condensed formula for benzaldehyde is wrong.
>>7981917
chemistry is easy
I mean i am serious when i say i have no clue what this stuff means.
>>7981921
Maybe for you hell I'm just training to be an emt, so i'm on the lower end of the spectrum here.
How did you do in highschool math /sci/? How hard did you find the material, how much did you study, what did you end up doing after highschool.
I got 95% in pre calc and 90% in calc. Did all the homework and reviews, went to all the classes. Ended up being a plumber.
I got like 80% in calculus I and about the same in pre-calc. Now on my way to studying nuclear engineering, probably going to get BTFO when I get to the serious stuff.
It was a breeze for me in many ways but that was because I loved to read about more advanced subjects so I always was 2 steps ahead from the class. I don't consider myself much smarter than the average, I just found it fascinating since I was little.
I graduated about 2 years ago now, goofed off in pre-calc with my friend and got about an 80%, in calc we got our shit slapped and had to bunker down, still only managed to get an 80%, and in my AP calc class that my friend didn't take I managed to earn the credit and got with guess what, 80%.
Is there any benefit to using MATLAB for scientific simulations over Python?
Python is free, more portable, etc. I've completely changed over. What are your thoughts /sci/?
>>7978499
One good reason (and this argument holds for any language) is that a bunch of libraries just might not be available for Python (yet). Depends on your applications, I guess, but I have not come across a situation where Matlab would have offered me something that Python/Numpy doesn't.
>>7978598
Yeah I'm doing digital signal processing and have found Python to be pretty good all things considered
Somethings I re-implement myself but it's not a big deal
I have medical problems that prevent me from going to college so i'd like to study towards becoming a mathematician at home.
Current my curriculum is
Basic Mathematics Serge Lang
Apostol Calculus 1
Apostol Calculus 2
Gilbert Strang Linear Algebra(with the video lectures)
How to prove it a structured approach
Are there any improvements or additions that you guys can recommend? I'd hate to spend a shitload of hours on something when there's a better option.
>>7978514
Basic Mathematics Serge Lang
John/Courant Calculus and Analysis I
John/Courant Calculus and Analysis II
Strang Linear Algebra WITH APPLICATIONS
>>7978520
Thanks anon.
Also something iv'e noticed with Basic Mathematics.
Sometimes in the exercises section he adds a whole new topic like modular arithmetic and then never fucking mentions it again.
I mean what the fuck.
>>7978529
Almost every math book does this.
If /sci/ got together and formed a laboratory, what would we invent?
a shitposting bot
>>7976346
Idk but i got some NaBH4 and caffeine pills laying around somewhere
>>7976346
The scientific principals of shitposting.
It shall be called Principia Shitpostinca.
I can't find any actually funny, no-cliche science jokes.
Do any /sci/entists out there have some good original science, math, etc. jokes that don't suck?
>>7979038
Try proofwiki's jokes page, it's confirmed for the most autistic place on the internet. For instance
[math]$\int\frac{1}{\mathrm{cabin}} d\mathrm{cabin}=\ln{\mathrm{cabin}}+C$[/math]
[math]$=\mathrm{houseboat}$[/math]
>>7979061
Shit...How do you do display math on /sci/?
>>7979064
It's easy! Well, not that easy. But it's better now than it used to be.
1) First, whatever LaTeX code you wish to employ, must ultimately be contained in the body of your 4chan post, and correctly formatted, /before/ you hit "post".
2) 4chan, specifically /sci/'s native implementation, entails that you must always enclose the body of your LaTeX code inside "math" tags, which are specific to this board, and not generic LaTeX commands as-such. In front, simply type "math" without the quotes, and then enclosed in the square brackets, for a total of 6 characters. On the end of whatever you're writing, do the exact same with the /single addition/ that you include the forward-slash / in between the left bracket and the letter m. This declares the end of your math code. IIRC "sci" tags have accomplished the same thing in the past here, and maybe they still work, but I haven't tried them in well over a year. Maybe they work too.
3) I don't think the mods or hot pocket men appreciate threads specifically about LaTeX, which can be frustrating for a beginner here. Still, the "stupid questions" threads are tolerated, so they're as good a place as any to sandbox when necessary, just don't be a nuisance with it.
4) in the quick reply floating window, which can be accessed by clicking on a post number in a thread, at top left of the window is a "TeX" symbol which leads to an internal sandbox space where you can work on your thing. It is now (finally) fairly robust; about a year ago when mootikins was still in office, the board outsourced this sandbox function to a third party site, and functional pieces of code I'd write there would not port to this board. Something about math mode, or not having the right libraries/implementation worked up. It's been mostly fixed for now.
5) For maximum legibility once you're confident enough to use large operators, I /strongly/ recommend always declaring /displaystyle right at the beginning. For the rest, search.
So if "it's not the volts that will kill you, it's the amps" then why do all the warning signs around electric fences say "DANGER: HIGH VOLTAGE" and not "DANGER: HIGH AMPERAGE"?
>>7975167
V=IR
>>7975167
Because that statement isn't true. It is the combination of the two that matters.
>>7975167
>it's not the volts that will kill you, it's the amps
These meme need to die.
>it's not the bullet that kills you, it's the loss of blood xDxDXDD
Should we be afraid of designer babies?
>>7978543
Not really. Designer children will eventually replace all the newer generations of 'normal' children. The normal people like us will be long dead before a conflict between superior humans and normal ones can occur.
>>7978546
Why are you so sure anon?
>>7978602
Can't be 100% sure, this is just my prediction. Feel free to suggest an alternative prediction, if you have one, or offer criticism to mine.
