As a complete moron who frequents this board out of admiration and aspiration, i've decided to actually try and study some basic topics that are somewhat relevant here.
As i'm just starting out, anyone have any good online sources that can teach me the basics of calculus? Thanks guys. Pic unrelated.
MIT OCW
Download the PDF of the book Thomas Calculus Early Transcendentals 12th edition. There's a solutions manual floating around somewhere too.
Its what I reccomend to everyone that wants to learn calc on their own. It goes over all three calc classes, just learn some basic trig stuff and you'll be ready for Calculus.
There's a publisher called "Dover" that has some very nice books at a very affordable price as well, just stay away from Kindle versions. I've heard Kline's Calculus is very good as well from Dover, but I have no experience with Kline.
KhanAcademy will be perhaps a little easy, but helpful if you get stuck while working on other resources
Quick. What's a good, quick (ideally small?) software I can use to take a 3D molecular molecule and animate it (I just want it to rotate 360 degrees and have it in a short video clip). I want one of those animations like some Wikipedia pages have (look at the page: amphetamine, nice animation there).
Pic related. Molecule I want to have an animation of.

A molecular molecule? Thats pretty advanced
ChemDraw/Chem3D might work

Can I export as a video or some shit or will I have to film the screen?
Maybe (literally filmingit) would be cool and add some nice effect to my vid with the shaking. I'm trying to make it kinda shitty on purpose.
What's the point of performing science if the way things work (the "laws") could change at any moment? Can we safely assume they won't?
Pic unrelated
What do you mean they could change at any time ? That a theory could be proven wrong or that the actual reality could change (for example gravity stops existing for some reason)
If it's the latter we'll probably die a few seconds after the laws change so who cares.
If it's the first then you can still adapt the theory if it's true in most cases, until you find a better one.
They're only going to change if we have enough evidence of them changing. As in, we have to conduct scientific experiments to discover that happening.
I feel like you need to reword the question or something.
>>7965991
>the point
>induction question
Not /sci/, reeeee, go to /his/, and such
Can someone explain me why *any number*×0=no possible
>>7965900
Can someone explain what OP is trying to ask?
>>7965902
0*0=no fucking possible
>>7965907
0*0 = 0
I don't know what "=no possible" is supposed to mean, but I'm beginning to get the feeling that this is a schizo thread.
Hey, i'm new to this board so this is my first post.
I was wandering that if light is invisible (you can only see the things light reflect on), what happens when you look at the SOURCE of the light? i.e a light bulb or the sun. Are you still looking at something light as reflected on?
You see the combination of all colors since none of them is refracted, which is white. Actually you'll see more of a yellow color because of the atmosphere, but if there wasn't one it would be white.
>>7965859
so does this mean you are seeing light directly?
>>7965843
I think you meant to post a bear as your picture, delete and try again.
I know asking about this stuff is generally frowned upon here, but I feel like this would be the best place to ask.
I'm going back to Uni (my degree is in History and Politics) to study astrophysics in cosmology. It's always been something i've been passionate about, and i'd love to learn more about it - but how useful is it in the real world?
If it turns out to be not very, what other physics-related degree could I get that would actually help towards landing me a good job?
My credentials are as follows: (may not be eligible for the more advanced courses)
-Degree mentioned above
-A in politics (A-level)
-A in mechanical mathematics (A-level)
-B in Physics (A-level)
-B in philosophy of religious studies and ethics (A-level).
I know this post is messy, and I apologize for that - but any information regarding anything i've asked about is appreciated. Thanks.
>>7965781
you just learn? for fun? these are bachelors degrees? Does your dad pay for it or what, i dont really understand
>>7965791
I thought my first degree would be useful, boy was I wrong.
I'm 25 and have a job in river island.
I come from a relatively well-off family in the UK and can afford to go back if my family believe that it can actually get me a job outside of retail.
Yes, these are bachelors.
>>7965799
You need to have faith in yourself that you can get a decent job without a field appropriate bachelors degree. It's what most people have to do.
how does h approach zero such that we get derivatives? if we can't have it be zero, how do we get a function which outputs every value of the instant change of y/x?
i know i'm stupid. i apologize for that. but i will not give up.
>>7965758
you should revise the formal definition of the limit to get a better picture of what it means for h to approach 0
>>7965758
Because we're looking at the limit as [math]h \rightarrow 0[/math]
>>7965758
Are you that guy from before who kept talking about atoms and denying the concept of limits?
Hey, /sci/, can someone teach me the basics of physics?
What do you want to know, exactly?
>>7965761
Light? Can somebody teach me about light in physics?
>>7965756
Why don't you learn it yourself?

I studied computer engineering as my undergrad and now I'm interviewing for a QA Engineering position tomorrow and a Software Developer the day after.
Will I be okay if I get one of these jobs? I know C, assembly, python, and to a lesser extent Java.

You will almost for sure get the QA job if you show drive.
I worked as a QA intern and it was the most fun I ever had. Sure QA is a lot of monotonous, repetitive, checklist type work, but it's a lot of fun if you make it fun.
I automated a lot of shit in our team so I also had that going for me. My internship I was a software development intern, and I found this less fulfilling than the QA position.
The software development position should require you to be more comfortable with basic data structures and coding. There will probably be a whiteboard coding session where they ask you to implement something similar to fizzbuzz.
Just be a personable guy. Show a sense of humor. Don't be too uptight. You'll be fine.
Good luck! =)
I had the same problem , I started as Software Developer in Test when I graduated. However I found more difficult to switch between Test/QA Engineer to Software Developer than Software Developer to QA/Tests Engineer, just because recruiters have some misconceptions of those two roles.
whats a good introduction book on number theory? I also need exercices and solutions.
Solve the Riemann-Hypothesis

aight so I spent like 5 minutes looking at it and I think it's probably true, got the solution so I could check?

Hi there.
French undergrad math student here.
I've been looking for a native english database/blog with accessible papers, but until now I've found either hardcore articles (AMS etc.) or blogs with short highschool level topics.
Do you know good websites of this kind ?
(Also, math blogs thread I guess?)
>>7965554
Terrence Tao's blog is nice
ohohoho oiu oiu?
>>7965554
You may like this OP

but really, you should git bon and read Grothendieck, Bourbaki etc in your own tongue
How would I go about making a mentaculus?
I wanna discover the secrets of the universe and shit
>>7965547
Fuck you
It's science
and shit
(You)
If you're all so smart why can't you solve these?
http://www.claymath.org/millennium-problems
I've solved one so far and i'm waiting for my reward!
>>7965513
Found what you solved. http://www.claymath.org/millennium-problems/poincaré-conjecture
>>7965513
They're too mainstream for me. I'll leave them to the meme spouting brainlets. I prefer to solve obscure math problems you never heard of.
>>7965522
so you're to much of a brainlet to even solve ''mainstream'' problems? Thanks for telling us that.
>every time you solve a captha you're secretly training machine learning algorithms
how do you feel about this anon?
fine because I regularly replace specific words with nigger
every time I get it wrong I'm secretly teaching machine learning algorithms to shitpost
>>7965315
>secretly
Considering how often I fuck up, I might be setting machine learning back a few years
