Im a CS kid but took an econ class. I haven't read shit for supply/demand graphs and couldnt be bothered to figure out what they actually represent lmfao. I just memorized that if supply goes up, then the funny line goes one way instead of the other. Prolly my own incompetence but they way they word these econ textbooks genuinely gives me an aneursym. Its like they purposely try to make it as hard as possible to understand. Compared to a book on math proofs, math proofs are so much easier to understand cus they dont muddy the conversation with random bullshit lol

Funny as hell lmao

Yea as someone who graduated community college with a business admin degree and then a private college with a finance degree, the troglodytism is absurd in our field. People don’t understand the most basic concepts that are just fundamentally true like if you add 2 to a number it goes up by 2 and if you take x2 and subtract x1 and then divide by x1 you get growth rates. Legit knew people who couldn’t write a paragraph in even 60% readable English(as native speakers) about how advertising would increase potential customer base. These were all seniors in Finance.

@@MinecraftPigSniper " if you take x2 and subtract x1 and then divide by x1 you get growth rates"? What does the "x" mean. Edit: The numbers in x1 and x2 are subscripts, so x1 and x2, and just two different "x-coordinates". I just didn't realise they were subscripts. Also, in the context, it almost seemed like an operation (multiplication), since it's right after having spoken about addition of 2. Thanks for the clarification.

@@aycoded7840 I think they mean the percentage change in growth. e.g a company makes $10k in month 1, and $12k in month 2. So ($20k - $10k)/$10k = 0.2 so the growth rate from month 1 to month 2 is 20%

Econ is brain dead easy until your professor tells you to download R. That’s when you get your real stats focused shit (and programming)

@@josephburchanowski4636 Econ's replication crisis stems from the lack of historical economic data- GDP as an indicator isn't even a century old, so we've always had to make do with things like grain wages and baskets of goods that we inference were historically considered essentials.

Yeah you have to remember that physics data come from experiments that can have flaws and human errors. Like maybe I diluted this thing one more time that I should 😅. And that's why sometimes when you see so fucking big error you can just say yeah someone fucked up this sample. Because you know other option is to full recreate experiment to obtain new set of data.

There's the data science gulag for bad analyses and bad interpretations of data, but just deleting data you don't like is deserving of actual academic fraud jail tbh.

Unfortunately, modern-day academia is "publish or perish." And also, finding results gets you published while "I did the experiment, nothing of note was discovered" doesn't. Combine these two and even people who know better can get pressured into just falsifying data.

@@warpig2148 that's cope. Unless you save the ID and diagnostics for each data point and can prove that the outlier is caused by known bugs or human error, you can't just assume it is bad data. The proper course of action would be to adjust your base model assumptions, or accept a lower r^2 value.

Yeah but let these labcoats keep their superiority.

Exactly. Macro is the only Econ that is repsectable and even that has some serious problems.

It also rubs me the wrong way that he’s talking about people in introductory courses. The intro course was probably just as easy for many other people in the class - and the people who struggle will not end up with degrees in economics.

Maths students are up there in smugness, only behind law and medical in my experience. Also, the engineering students I know (I studied computer science, but it was the same campus) all had the joke that physicists are just engineers who can't do math or talk to women. Everyone makes fun of everyone, it's the law of academia.

As a STEM major I dislike how smug STEM majors are. While there are certainly deadbeat business majors there are also plenty of chill ones because they aren’t smug a**holes who have a superiority complex over those that aren’t as smart as them. Like someone else mentioned, saying that students in introductory business courses are going to be running banks in a few years is ludicrous. Anyone not cut out for an introductory course isn’t making it through a major. I think these people would be suprised at the difficulty of more advanced econ courses (I have a brother who did Business Econ at a college that basically required regular econ courses.) Furthermore, many professions that Business leads into are very much work your way up the chain kind of jobs. It’s also important to note that many of those students are coming straight out of public highschools with extremely low standards for non-advanced classes. People need to notice the log in their own eye before seeing the speck in others, so to speak. On a side note, I found it funny how the video creator couldn’t fathom that a professor would want him to round in a pretty standard way😂.

@@krkngd-wn6xj As a maths graduate, when I hear somebody who never studied theoretical maths saying he knows maths I will always react with smug "ohh, that's cute".

Problem about this guy he did not took an Econ class or been on same class with econ students, he was in Business Econ, with business students.

I was taught this method of rounding past 3 decimals as well but also think removing 5% for it is incredibly silly

The issue is the conflation of two different methods of reporting an answer. With the ... (ellipsis) then you aren't expected to round as you are reporting that more is to follow, whilst if you don't include that, then you are expected to round, though you often need to report it with a note to the effect of "to 3 decimal places" so it's clear what you've done. The professor seems to want him to do both.

Also truncating has the possibility to introduce bigger error than rounding

Yeah I would've rounded this way to

I’ve got a PhD in material physics, and I got the exact same reaction. Rounding to the appropriate amount of sig figs *is* the correct standard procedure, truncating the answer without rounding is wrong. I’d give some minor points off as well if a student handed it to me like that. Especially if they keep repeating the same truncating scheme in subsequent assignments.

.763 and ".762..." Should both be valid answers though, as the ... implies additional digits in the answer. So there should have been no markdown.

@@adbon6279 i mean thats what sig figs are for, you have a system to determine if you round from the tenths, hundredths, or whatever place and its consistent. ok normal rule of thumb i learned in stats is to go 4 places past the decimal point so you can say 76.27% in this example instead of 76.3% and the whole thing with the dots is just objectively wrong but there is a system (that the prof only half followed)

I remember in my stats we rounded nearly all of our numbers. Statistics is already an, "arguable," set of numbers. Like on surveys people lie, or methods of gathering data may be flawed. So a .00000076 difference isnt going to make a significant impact. Certain types of information need different amounts of specificity, like if you are testing measurements of liquid, youd want like 5 decimals. Where as if you are counting descrete data, like one person, or one cat, you cant have, "half a person," that doesn't make any sense. So you have to make it the closest round number.

There are still some baby easy electives at higher level though - game theory was baby easy for me but pretty much EVERYONE got bad grades on those tests somehow. Your peers will kinda get better too. Some who weren't ready for it select out and you will learn which ones are worth hanging around, either because they try even if they're not smart or they're smart and can help you with things too As a double major in Finance and Econ about to graduate, things are the same way on the Finance side too. I've had amazing classmates that I would want to be friends with if I wasn't busy with my own. Group projects are the worst though. I also had a guy who did literally nothing for a large chunk of the class in my 2-person group project based class last semester. It close to ruined my homecoming and semester because of the work that got shipped off to me. He later put on his resume that he put 40 hours a week into THAT ONE CLASS, and got into law school with that banger experience -.- Anyway try to take the non-business version of classes if your schedule allows, and diversify your classes. My program let me take a bunch of math (not enough for a minor though), stats, and some Python along the way. Your bosses will be impressed by the fact you know what an integral is (this really happened at an internship, it's not a theoretical), or you'll be a bit ahead of the curve for grad school if you go that route, if you know about Finance at all I'm doing CFA level II right now and really happy I did some of the "harder" electives before it Anyway I was bored and typed this hopefully you find some fulfilment in your major and make money

@@trollinape2697 a lot

​@@trollinape2697 Highly dependent on whether you work on the theory side or the experiment side. Both will require you to do physics PhD coursework, so you'll definitely need to know graduate-level maths while getting the degree, since almost all physics coursework is theory. (Of note for folks that want to search for more info, "particle physics" and "high energy physics" [HEP] are used pretty exchangeably these days since most particle physics is done at high energy collider experiments). In practice, Particle Theory is the continuation of the PhD coursework. My understanding is that knowing things like group theory, Lie algeabras, and other advanced maths is critical, as this is the foundation of quantum field theory, (which, itself, underpins all of modern particle physics). I'm sure the maths specializes as you begin to focus on a specific thesis project and career interests. On the experiment side (where I currently am), it's a mixed bag. Phenomenology is a very theory-adjacent subfield where physicists will model how specific theoretical particles will decay/interact with specific detector components and try to understand the specific signatures there. My understanding is there's a lot of field theory used here, too. Doing physics analysis from collision data (or calibration work, or precision measurements), you will typically learn a bit of quantum field theory at the PhD level, but the research is mostly statistics. My thesis is a particle search analysis and I haven't touched actual particle physics in a few years (and need to go and review things like the Feynman rules, etc for my defense). I still do a lot of math, but mostly I do statistics calculations and I write programs, so the computer actually does the math. Still need to know how to do the math, though, to know what you need to calculate. Most important things to understand are Bayesian statistics, likelihood functions, and how maximum likelihoods are calculated. Also, propagation of uncertainties, and knowing how to calculate both statistical and systematic uncertainties is key. Then you have hardware work, where you actually build detector components, solder chips into PCBs, write firmware for FPGAs, etc. If you work with a group that does any hardware development work, you can get exposure to a lot of different projects. How much maths are actually used varies. I've never done hands-on hardware development, but usually you're involved in both the fabrication/testing as well as the design, so there will definitely be math used in the design portion. I have done some FPGA work, and that's all programmable logic and binary arithmatic, so you'll need to know at least some basic algebra for that. Most of the FPGA stuff is doing signal processing calculations, though, so that'll require calculus and an understanding of things like Fourier Transforms, etc. Overall, quite a bit of maths for particle physics. If you know the kind of work you want to do (and what skills you'd like to learn), it's likely there's a project in HEP that will teach you those and more. The trick is finding a group doing the kind of work you want!

Can't say I've seen anyone write ⅔ = 0.7... before. ⅔ ≈ 0.7, sure. But never with the "..." (To be clear, I would happily write ⅔ = 0.66..., and use "..." notation often for intermediate steps of a calculation)

in my analytical chem classes they tell us how many significant figures they want, idk if the econ prof was doing that.

@@camicus-3249 yeah honestly the ≈ came up a lot more, I saw the ellipses in early science classes but only until we'd covered significant figures.

​@@rez505exactly this, I've never seen the ... used in proper calculations before

id assume that if a number ends in “…” it would be truncated and not rounded. (would be weird to round if you are saying there are more digits after. the point of rounding is to cut it off)

No child left behind is hilarious

Yeah I was wondering about that too, wtf is going on with grade inflation in the US?

f(x) is f times bigger, so ∫xf(x)dx = ∫x(f+1)dx = (f+1)∫xdx = f+1

@@raspberryjam Is that assuming x=1, or does this work in the context of x being any type of function or value?

@@raspberryjam that's... not how that works

@@raspberryjam Can't tell if this was supposed to be a funny meme

@@raspberryjamCan’t believe you forgot the + C. Rookie mistake.

Yeah same, I was kinda looking at getting an econ major with a business emphasis but one semester in a business communications class was enough to push me away from anything business related.

Exactly

this guy is a real piece of work

They are absolute shitlords and insufferable knuckledragging apes.

We have 3 mainstream accepted theories of the universe each contradicting each other and 2 mainstream theories to this which contradict themselves. Go figure.

@@AnonYmous-spyonmepls ...That's what theories are. You can theorize that you'll crash on the way to work or be just fine. The contradictory nature of both theories doesn't say anything about the theories themselves.

Yeah, I took high school level physics and the first thing they did was teach us about significant figures.

Now I don't have to post this!

the presence of an ellipsis implies more numbers, meaning it's categorically incorrect to round the ones you already have

@@bayleev7494 Yes, but using elipses in that context is wrong.

@@rightwingsafetysquad9872 how do you know? by the sounds of it, a lot of the practice questions were basic calculus and algebra. if it were one of those questions, they would not necessarily have rounding conventions. also, and more importantly, the marker seems to have said it would have been correct to write 0.783..., meaning your logic falls apart anyway.

lmao

truncation could allow you to quickly check with your calculator without rounding that the given decimal is actually the same as the fraction

Yeah like he could have added like the equivalent sign and rounded the number to 3 s.f.

Found the econ major

Its insane how delusional the video creator is; salted sour grapes, truly a cope and seethe experience.

Exactly, you can't write 0,7626... in general. 0.12345 implies that the figure is accurate to 5 d.p. If I see that, I'd assume either you have super accurate measurement, or it's divided from very large numbers. This is misleading.

Physicists tend to not round unless it's absolutely necessary. But he was in an econ class, so he should've done it the way econs do it

The problem was that it should be .762… or .763 not .763…

Me shifting my data just to get a silly p value down from 0.1 to 0.051 (I need it to look believable)

He complained he got minus 5% on his test for a completely arbitrary reason, pay attention when watching the video

sauce?

I would hope so, unfortunately the vast majority of companies, particularly ones controlled by rich assholes, DEFINITELY want business grads.

Why? I'd assume companies want to hire smart people?

@@darkthunder301 Yes, that's exactly why they want to avoid people with an MBA background.

​@@anjoliebarrios8906source: trust me bro.

Yes, economics and business are two completely different things. He took a business class and confused it with economics.

Well to be fair PEMDAS isn't accepted by everyone. Eg.: ab/cd = ((ab)/c)d according to PEMDAS, while a lot of people would say it is (ab)/(cd) It is a convention, that not everyone subscribes to. That is the reason for the debate about 6 / 2(1+2) = 1 or 9

​@@Teronix100There is no debate, there are the people who are right and those who are wrong, easy as.

@@SenhorAliennah not true. It’s slightly up to interpretation and so we are careful to be more explicitly in writing

@@Teronix100 , I wouldn't say PEMDAS isn't accepted per se. PEMDAS is correct as a convention and is used extensively. Rather, a lot don't understand that PEMDAS defines addition/subtraction and multiplication/division as equal in priority, an ambiguity. Parentheses exist and are the highest priority as they're used for disambiguation. It's up to the author to avoid ambiguous notation.

@@SenhorAlien , those social media posts about these are actually ambiguous, and both are right, since the author intentionally left it ill-defined. It's a great viral tool for them, since people will debate each other endlessly.

I mean, I understand it not being the highest grade, but bottom third?? What kind of statistic classes are you getting? Everyone passes with an A???

​@justsomenightowl7220 the *exam grade* (the 78%) was bottom third of the class, not his final grade of that whole class, which was a 92.5%

Yea, the english system is way harder. I cant speak for the university level, but i did both high school in an english and canadian system. I was laughing with every math question in the Canadian system and averaged a bit over 90%. Which is also harder than the US system by the way. Whereas i was fighting for over 70% in the English system. I used to think i was just retarded, then i realized why Americans think they are so smart!

​@@justsomenightowl7220No, it's all graded on a curve, so it's as unlikely for someone here in the UK to score 75% as it would be someone in the US scoring 95%. Basically you can lop off the remaining 30% because unless you found and answered the secret, hidden questions, 70% is 100%

@@josephvictory9536it’s funny though how England performs considerably worse in OECD testing, then both Canada and the US. Complicating math doesn’t mean you learn it better.

have... have you never taken a class with obtuse and impossibly harsh assignments/markers?

Because he’s too smart for doing silly stuff like reading the syllabus:))

@@bayleev7494 He was in the bottom 1/3rd of the class lmao

​@@bayleev7494You would lose marks on a high school exam in Europe for that mistake.

@@unknownfugitive225 i wrote about this in another thread, but the mistake he talks about is completely inconsistent. he was marked down for not rounding his answer, but when you use an ellipsis you are not meant to round. (ellipses indicate that there are more numbers to come.) you might say that using an ellipsis was wrong in the first place, but the marker's answer also used an ellipsis. so no, if you were in high school and got marked down for that mistake then that reflects poorly on the high school, not you.

Lol polar opposite for me. I fucking looooved calc but took a discrete math course and got ass grades

​@@honkhonk8009 which of your 11 hard science PHDs was the one that you sucked at, Dell?

Typical STEM superiority

>Has a physics degree >Calls all economics students dumb >Knows the difference between rounding and truncation Yup, he seems about right.

Because he probably wasn't asked to round it. The ... means there are numbers he is omitting. Technically, that's the most precise answer. The professor probably expected him to round based on the lowest number of significant figures (3 in 781). But since this isn't experimental data, there was no reason to assume that convention from the student's part.

@@Blade.5786 : _"Because he probably wasn't asked to round it."_ There's nothing to indicate he was asked to report his results in the silly truncating-ellipsis convention either.

Report her to admin, and get as many people as possible to complain simultaneously. If possible, involve your parents and others parents. If you can find evidence of bias where similar work by you and another person were given different grades for petty reasons then she’ll be given a headache at the very least. Don’t take this lying down, it’ll never get better if you don’t complain above her head.

@ianrau6373 nah, she hates everyone in my class equally. Also I go to a private school, so what's right isn't what happens. She knows people, and she's been here a few years now, which is longer than I have been. I'll just be labeled as a troublemaker and expelled.

if she’s doing it to everyone maybe she’s just trying to hone your skills? if the rules are consistent at least. personally i think english is probably one of the most important classes you can take as a senior. being able to write well is good for any job

Give us some examples, that way we can know you aren’t lying. Just out of reasonable doubt

@@chesspiece4257 I personally find English classes one of the easiest for teachers to teach you rules and the likes that are completely and utterly useless, such as the so-called 'split infinitive'. And, perhaps another one would be marking down students who use phrases that don't form a complete sentences by themselves. I mean, phrases are used everywhere for emphasis and effect-newspapers, letters, books, etc.-that teaching them it's ungrammatical hurts their writing and is also wrong. For example, this excerpt from a novel, "Our lives took the forks and turns and twists into our own paths-into dark forests that sometimes felt impossible to survive. All leading to this moment. (Here, the phrase solely consist of a gerund-participial verb, which does not, in a traditional sense, meet the requirements for a sentence.)" Or maybe the 'rule' that conjunctions such as 'And', 'But' or 'Or' can't be used at the start of sentences. For example, this excerpt from another novel, "...spilled out in tears and screams and in heavy, pulsing silence. And somehow, as much as I hurt, I knew it was even worse for Dad." Revisions: *For your convenience, some missing words have been added back in. Some stupid issue with italics and bolded letters being deleted. And so there goes all the fancy formatting!

I'm pretty worried watching this vid as an accounting major that doesn't really know calculus or functions that I'm pretty clueless on the math he's referring to, like the function he put on screen made no sense to me. Am I just boned or is that really unecessary knowledge for my career coming up?

@@waxcutter9813 it's mostly unnecessary. The video creator is just being a hyperbolic snob and telling us what a bad student he was that he spent an entire semester unable to round the answers the way the professor wanted, lol.

This is what any person with a major complaining about other majors sounds like to me tbh, including those in this comments section. Insufferable.

We will pray he gets out of this phase soon 🙏 it's very obnoxious!

@@waxcutter9813 You can trust that the things you learn in university are the things you ened to succeed in your career. I don't think accounting is known for complicated mathematical models. But, to counter the narrative of the video, that doesn't mean the major doesn't come with its own challenges. They're just different from understanding complicated math.

It's better than him looking through his phone, wondering why the teacher wanted the number of his ex.
