Hello /sci/, I'd like to ask you about your first job related to your major, so that maybe we can visualize better where does a STEM education actually lead you.

Please structure your posts in this way

>Your bachelors degree
>First job title
>A description of what you did in this first job
>Satisfaction

Restrictions for what counts as a first job:
-It must be related to your major and what you were taught in said major. That means that your time delivering the paper doesn't count as your first job.
-You must have been paid for it. That means that slavery/unpaid internships do not count.
-It must have been in industry. That means no 'academia researcher' or anything to do with a university. If you do research for a private company then you are ok.
-It is not necessary that you graduate college, as long as your job is already related to your degree. So your paid internship or part time job counts as a first job, as long as it is related.

And if you actually started a company in your own field then feel free to get that as your first job.

And if you are in your mid or late career then feel free to continue with
>Any further qualifications after your bachelors
>What you have done since that first job

Hopefully this thread will be helpful to everyone, and hopefully we will get someone from all disciplines here. Please no memes and no fights about what major is better.

I will get us started

>Mathematics
>Software Developer
>I work under senior staff and basically implement what they order. This goes from tinkering with UI to implementing from scratch big data crunching algorithms that spit out big reports and statistics from the raw numbers stored in the company's database.
>My satisfaction is around 8/10. I enjoy what I do but I hope to climb the ladder up to more scientific computation.

Well, you don't need to have graduated. Any paid internship that relates to your field is acceptable.

I know there are people here with actual jobs.

Kepler had some difficulties for a while, not sure much was observed then. Also a shutdown to safe mode too, recovering just the other day. Observations will probably recommence.

How do I integrate this /sci/?
I've tried integration by parts but end up with even uglier integrals containing arctan (x)
I also tried substitution but couldn't find an appropriate term to substitute
Pls help

Partial fraction decomposition.

Trig substitution. The -2x/(x^2+1) integrates to tangent
>>
>>7999051
What exactly would you substitute? I tried using the fact that 1/(1+x^2) integrates to arctan(x) with integration by parts but that left me with even uglier integrals

Block websites that make you procrastinate (eg. 4chang) in your hosts file. Uninstall or at least block access privileges of vidya. Do not attempt to study where you live or sleep, instead go to uni or the library. Eat healthy, drink green tea, sleep 7-8 hours a night, masturbate less (once a week is OK).

Things your body need taste better. That's why preggos crave weird things and some people eat dirt.

"Hunger is the best sauce" so they say.

Some kind of neural response to avoiding a dehydration situation?

>>7996617
Because you're dehydrated

>>7996640
>>7996644
Makes sense, I kinda thought of that but it doesn't really taste good. Milk is better anyhow if you're hungover imo.

Hey, IQ fags, if pic related means I'm smart, why do I feel so dumb?
94 posts and 13 images submitted.

>>7996303
Because online IQ tests mean close to nothing. However you're probably not stupid. Dunning-Krueger effect and all.

>>7996303
Because if you genuinely took an online IQ test and think it means anything you really are dumb
>>
>>7996309
>>7996312

I am aware that it's not a real IQ test as a real IQ test consists of several different types of tests, which aim to measure reasoning, spatial awareness, short term memory, etc. Your overall IQ score is determined by how well you did on all of the tests.

The test in the OP was designed by two mensa fags to specifically imitate the spatial reasoning tests that are present in a real IQ test. From what I've heard, it's pretty accurate in that regard.

Hello sci/

I'm not very educated when it comes to the sciences. I did well at my academy, and took rudimentary courses in college. My passion in life is reading and writing. The latter has taken some of my time lately.

I want to write a story set in a high fantasy universe - highly original I know. I wanted to have a lot of the subject matter be sound to the average reader however: iron is iron. You forge it to make rudimentary steel, copper with a little tin makes bronze, and so on. I do not want any kind of wacky, new metal that trumps them all.

I do want different kinds of metals brought into the equation. Like a steel word imbued with a little aluminum to give it a lighter build. If that is even possible that is. I want some of you chemists and blacksmiths on here to recommend things I can read on this subject. If you could, you could even suggest some various things I could add into this world's metallurgy to make it seem grounded despite being set in fantasy. Thank you and I look forward to any help offered

I don't know much about the actual metallurgy but these videos should help you avoid the most common mistakes.

Also, be sure you don't just rewrite the Lord of the Rings.

PET scans are an application of antiparticles. Would be pretty cool if some physicists here gave other technological applications of subatomic physics.

Pretty much.

It keeps thousands of scientists from unemployment though.

Do you really want a second tobacco industry?

Legalizing the drug itself is okay, but I think we should maintain a ban on commercial sale. Let people grow it themselves if they really want it that badly.
>>
>>7991046
Like what? Instead of wasting tons of money cracking down on a drug that isn't even dangerous, they could increase tax revenue. There's no reason not to even if you hate weed.

Honestly anon, why are chemist so undervalued in society and the workforce. I know the chemistry meme but chemistry can be very complex and fundamental to the world that we live in. Have we just hit the ceiling of world changing chemical discovery?

Can someone explain to me intuitively what exactly is going on when we integrate?

I understand that it's used for finding the areas under graphs, and I know the method, but what am I actually computing? With differentiation, we're finding the gradient at specific points using a line which has a difference of 0 between our point and another arbitrary point. I don't, however, understand what integration actually is.

Youre summing infinitely many rectangles with height H and width lim x --> inf for 1/x
>>
>>7989422
You are taking the sum of "thin slivers" under the function. You then take the limit of the width of those slivers as they go to an infinitesimal width, dx or whatever.
>>
Its just essentially an antiderivative. If you know derivatives you can understand integrals. Id you take physics youll see it clearly
