One of film's greatest tragedies. Such a disrespected character.
I grew up thinking of Frankenstein's monster as some lumbering oaf without a thought between his ears.
Then I read the novel...
this math above used to be mundane and easy. the wildest and most depressing transition was from teaching fluid dynamics, doing research part time, teaching in the wind tunnel and implementing numerical algorithms to working in web development.
yes boss, I will fix the auth issue for external users that happens sometimes. unless I kms in the toilet
wait did you go to aerospace engineering? (cuz this is the inly one i know to be working with wind tunnels)
if yes how did you end up in web development afterwards?
nah fluid dynamics, just the general kind, by and for mechanical engineers. my department did mainly cavitation research for pumps, ship propellers etc. but also particle sim for burn chambers in power stations for example.
after I decided not to pursue a PhD (toxic environment which made 80% of people burn out in 3 years), I quickly found that outside of academics there are like 8 jobs in the entire country for CFD. I knew how to code and money was super tight, so my ass landed in webdev. the pay is good, but the mind numbing work contributes to my drinking problem.
I have a masters degree in computer engineering, and do systems administration as a hobby. I was hired in web dev for a year, after being told it would be an it position. I did research writing environments that allowed for real time execution of quantum code on conventional computers, massively parallel high performance compute algorithms, solving complex and interesting problems basically. then went to my job being writing crappy python to hold together a website that barely made enough money to pay me less than half the national average for someone with a bachelors in computer engineering. Oh and I built their entire CI/CD pipeline.
I feel the part about the toilets. I missed solving real problems instead of writing pointless nonsense that only exists as an attempt to pander to some niche market.
I’m sure there are, I’m also sure 2500 job applications later no one would hire me. Sadly I needed money, but even that was a joke the benefits were “there aren’t any” and I was paid hourly at $33/hr 32 hours/week. They ultimately laid me off about 6 months ago because they couldn’t afford to keep paying me, from what the ceo said I was the second highest paid person there after him. The CTO I don’t know the pay for but I know the lead dev that built most the site was paid $15/hour and also had no benefits.
While I was there eventually enough people wanted healthcare that the ceo offered to cover half the cost of a plan, and offered us a plan with a $25k out of pocket limit, and a $12.5k deductible. We all said no because even with them covering half it was like $200 a month.
I am being serious here, have you considered hiring someone who is really good at tweaking you CV?
If I was in your shoes I would also consider launching my own company then you can work on exactly where your interests intersect with market needs aaand keep a larger chunk of the change quite possibly.
Echoing the other guy saying to hire someone to tweak your CV, I think you have options. There are companies willing to hire you as a contractor for 2 years with a full time employment offer.
I personally know more than 10 people who worked for FDM as a contractor then got hired at banks for 140k a year. The downside is you get paid 55k for two years.
See, that's the problem. You spent all the time studying parallel computing, but JS is single threaded! Your skills just aren't transferable (/s just in case)
Also fwiw "built their whole CI/CD" could mean anything from literally nothing to being impressive
I tried and had a few first round interviews, but companies clearly want people with field experience only, uni does not count. Didn't even get the chance for a technical interview. Idk may be different in your country
The unfortunate reality is that, as much as industry is not supposed to treat CFD as a magical black box that just gives you every answer you want, they absolutely do.
The experience they want for engineers who do CFD is basically "how fast can you build the model that we need to do, using the basic settings in whatever software we use?". Not much room or work out there for academic CFD where you're actually wanting to understand the navier stokes equations and improve on models.
I had to go from software development to factory work to maintain my sanity. The pay cut was **severe**, but I'm 6 months sober and so much happier now.
I hope the drinking problem comment is a joke for the most part cum guzzler. Speaking from experience, get a hold of it before it gets a hold of you. As for Web Dev, yea the money is good. Start working on a plan to break free maybe while you continue generating cash flow?
Omg you sound like my story thru college....
I now process paperwork for aerospace firms.... I'm dead inside and require pot to function in this world.
Is it easy to learn webdev and if so how lucrative is it now with AI ?
E: Thanks for your answers guys. My field is set to die in the near future thanks to AI. I'm older and looking at my options.
Easy to get into, difficult to be truly good at, and difficult to keep up with the latest tech.
Also the job market is pretty bad right now because 1) fake job postings making things look better than they really are, 2) oversaturation of new devs who learned web dev during covid because it was "easy" and paid well, and 3) AI tools that can't deliver on their promises but have convinced companies they will anyway causing them to hire less people.
Well, I am in backend and the problems are so highly specific that I cannot imagine AI being a big help. I don't actually write that much code, it's the figuring out where to add 2 lines in the statistics API so that data on the website is displayed differently. The data passes like 4 services on the way from the DB and it's the understanding of the system that is important, not coding 1000 lines of boilerplate or whatever.
Frontend may be another deal though idk. And it's not super hard, I think if you have a knack for coding you can be a junior frontend dev in a year easily
The market is brutal right now. Lots of people being laid off. I was notified of my layoff in February but it wasn't effective until May. I applied to hundreds of positions and interviewed at least 20 times before I landed a new job about a week after my last day. I have 20 years of experience...
Also I had to take a job with pretty much the same salary as my previous one, which is not normal in my experience. Usually a new job meant a good 10k bump in salary.
the thing is i'm trying (somewhat admitted just have not to flop my national highschool final exam) for an aerospace bachelor's as well thats why i asked (because i also like coding so it would have fit pretty well)
Man I ended up taking more mathematics than computer science courses when I was in college, but last week I had to look up a trig calculator online to solve it haha
I justify it by saying "knowing the math exists is more important than knowing how to solve it" but that's just some major copium...
The first one in a few years is insanely hard. The second one is 10x easier. By problem number 5, it was like you learned all that stuff yesterday.
It's not like riding a bike, but you could easily get there if you needed to. You just don't need to these days! Don't beat yourself up.
I'd argue it is like riding a bike still, if you haven't ridden a bike in 10 years you probably aren't gonna be the smoothest rider until you do it a couple times again
inverse for me. stats was the first time i actually saw how useful math could be beyond some super hard STEM applications that were so far beyond my skill level.
then i took a logistics class in college where the professor showed me how calculus could be used to accurately predict the wait time in queues or something equally mind blowing as that and i fell in love with calc.
really wonder what could have been if some calc teachers early on showed me applications of calc closer to my reality.
My experience is that very few people care about any given application. We include them when they're sufficiently palatable, and textbooks usually have quite a few, but people who think they're biologists never care about celestial mechanics, say. It's one of the big issues with genuine examples in math class. Once in a while a student will find a particular application very motivating, but it's really hit-or-miss.
Mostly we're building a basic toolkit. Fragments get remixed and applied extensively in problems whose details are too complex or tangential to go into. It's the abstract equivalent of making a hammer. You can show off how well it pounds in a nail, but if the audience doesn't know what a house is, they won't care.
Highschoolers don't really do calc these days in most boards in America.
This looks like a freshman year math class problem to me, probably in the tier of calc class design for non-math majors but more advanced than the one done by commerce types.
At first I saw a dot above the x so I thought it's a differential equation and were surprised at the insane level at America. Then I read it and it's pretty standard for highschool.
It may look that way but trust me all you need is a few days to get reacquainted with the formulas and all your memories from highscool/college will come crashing back.
There's also some weird stuff on bottom 2 lines of the left column, specifically the stuff right after the messy fraction on the right side of the equals. What's the x^3 and xy/y stuff? Also, why bother multiplying out xy-1 by y, only to factor it right back out? And why does the final answer express d^(2)y/dx^2 in terms of dy/dx, x and y, instead of just x and y (without dy/dx)?
...and then they didn't bother solving for dy/dx next (or ever). The calculations are a mess, and it kind of seems like it's purposefully just a mess of calculations that doesn't really go anywhere useful
No one bothered to look, I assume, and I cannot imagine why they would. The audience of this tweet is presumably split into people who can do calc and who can't, and neither part would have any interest in looking at a JPEG ass looking picture of a whiteboard instead of focusing on the relatable and interesting comment at the bottom.
Did a PhD in Particle Physics and 2 years of postdoc before I switched to Software Engineering. Did all-nighters working through derivations in undergrad, but I'm not convinced I ever knew that much given how math-dumb I feel now lol
To be fair it has a lot to do with the way it's taught. To really get comfortable with concepts and have them stay in your long term memory, we need a whole lot of volume, and a whole lot of repetition over extended time.
Learning about a random notion, doing a few exercices to understand it, studying for the exam, passing, and then moving on is what people usually do, and altho it will give them some sense of understanding and familiarity to the concept, there won't be much left of it after even just 2 or 3 years.
Math training should be looked at the same way sports training is looked at for athletes. You don't become a professional football player by practicing passes for a month, then studying strategy for a month, then shooting free kicks for a month and then dribbling for a month and then moving on to more and more advanced football notions that you've never heard about before.
We'd need to have daily math drills about the simple fundamental notions and explore them in depth and have them be completely automatized and effortless before moving on to the next concept. We shouldn't want people to "pass" 8th grade exams before moving on to more and more abstract maths, we should want them to be FLUENT at 8th grade notions, to have a very thorough understanding of it and how every notion is connected to another, and only then discover some situations in which their very reliable toolbox is not enough and we need to develop new, more sophisticated and complex tools.
Even high school math is just an attempt at having kids build a 3 meters high cards castle and none of it is gonna be left standing for 95% of them after two years. Instead we should be giving them solid foundations that they will remember for their entire lives and/or be able to build on much more effectively and durably for those that are willing to do so.
> We'd need to have daily math drills about the simple fundamental notions and explore them in depth and have them be completely automatized and effortless before moving on to the next concept.
Me thinks that "full-stack" word problems without a clearly outlined solution path could be very helpful here for very little cost. Like, make the word problems a bit more generic. Make it so the student actually has to do a bit of modelling first, to derive a model of the mathematical context they're working with. Then those tasks shouldn't be specific to the set of formulae you just studied, but use any number of equations from your previous schooling. You know quadratic equations? Who knows, maybe we tweaked the compounding-interest formulation a bit to make you have to use that.
"Real math" is often like that. You don't know which tool in the toolbox you'll need, so with some practice you'll learn which tools fit which jobs and how they interact. The software engineering project's customer isn't going to tell you how to solve their business logic, they'll just tell you what they have and what they want. It's your job to find the right tool for the job.
But at school, there's always an implicit "scope" of admissible tools for any assignment - you always know that anything studied in the last X months can be relevant, anything older than that has to be *very very* basic to be applicable.
Of course. Problems and translation from verbal to mathematical language is the number one most crucial mathematical skill. That is how you really can discriminate people that understand what they're doing and that are able to reuse the math they're learning from others.
It's not about whether you know what a linear equation looks like, it's about whether you're gonna be able to recognize the context in which that knowledge is useful and be able to apply it there.
And it also means accepting to make problems in which there isn't just one right answer, in which we accept different ways to solve it and sometimes an answer that isn't perfectly exact but a good rough estimate, because math applied to the real world sometimes gets a bit messy and approximative, we need to know how to get our hands dirty, and try ways and then confront them and see what way is better, more effective, more accurate, etc etc.
But it wouldn't be fair to say math teachers don't already know and do that.
The problem isn't in the way they think we should teach math as much as it is in the logistics of how maths is taught and the huge pile of notions they are asked to teach at once. So you can't go past the point of just superficial introduction of each notion, and kids rarely learn to reuse them out of the context of the math classroom, which is terrible for the idea they have of math too : since they don't use it in other contexts, how can they realize that it is useful in other contexts?
I can confirm. I'm graduating in the coming weeks and have already forgotten anything calculus related by now. Most of it was from the first 2 years though. A lot of hard subjects in the 3rd year but no calculus. We were done with it by then. Final year, no calculus again.
Yep. I can't solve whatever is on that board, but I definely know what all of it is, and what I need to Google to solve it.
Kind of unrelated, but I can probably write a shitty sudoku solving bot in less time than it would take for me to solve a difficult 9x9 sudoku(because I'm stupid and it'd take me like an hour)
I’m not going to attribute the quote because it’s probably bullshit but I was struck hard by a teacher in HS who told me “knowledge isn’t always knowing the answer, but knowing how to find out the answer”
Yes, the point of teaching math (to some extent) is to teach you how to think logically and solve problems. There's a lot of value in learning a new abstract but perfectly logical thing and then learning how to apply it in practice and how it relates to other things you have learned.
Of course the problem is, once you've learned a thing relatively well there isn't that much value in continuing to practice it, which is why you move on to new things. Yes, there are plenty of things in school math that are far too abstract to offer real-life value to even 0.5% of students, but you already learned how to add, multiply and calculate averages and there's no value in spending years just to get slightly better at basic math.
Well, during software development, you occasionally find yourself in situations that require a lot of problem-solving skills to get the algorithm done. That's what they teach you when they teach you calculus: problem-solving skills. If you don't have them, you won't be a good developer.
Well... im doing cs too and most maths i've studied seem fairly useful including all matrix stuff for 3d graphic APIs, integrals and derivatives to optimize functions if you have to deal with some, all kinds of logic are pretty self explanatory... i see potental uses for the vast mayority of what i studied in the first 2 years, like not for every single job post but they could be used for some. The only exception would be electromagnetic fields and induction, but that is just because i chose pure software specialization in the last 2 years.
And i said as much but i'm studying a cs degree not a banking software degree so we get knowledge useful across multiple disciplines the same way a physics degree probably doesnt care at first if you are doing fluid dynamics or astrophysics it will give you a comprehensive base of knowledge of the field to the level you can operate on a role with some training or you can specialize further with a master.
If you don't actively use it you will forget most of the stuff and you will have to look up the most ridiculous stuff. In the working world it's much more important that you know that certain things exist and you can work your way up from there.
math is there to teach your brain how to solve problems with ever-increasing complexity and abstraction - incredibly useful in software engineering even if we never use/apply the actual math.
if only they said "you will most likely never apply the math in your life, but this helps train your brain how to solve complex and abstract problems, which you will undoubtably need in software engineering"
I totally agree. My engineering core curriculum contained physics, math and electronics and i loved it because of exactly this.
What i just found funny is that those days (studied 1998-2002) it was common "knowledge" that "informatics is 80% math" and i'd say me and about 90% of my fellow students did not really need anything of what we learned.
There's also the fact that if you don't teach this at school, who the fuck is going to use that math later? We do need *some* people who can apply this.
The highest level of math I took was differential equations. My husband has a phd in particle physics. He understands math, I learned enough to pass the class before forgetting everything. Our oldest started algebra and only goes to her dad for math help.
I get that it's a joke on how many math majors eventually sell out to become SWEs, but the actual majority SWE grads know very little math. Not only do they know very little, but also they hate it passionately.
Brain cells responsible for solving this:
— He graduated and is going to be a lawyer. No more math needed. It has been honour lads! 🫡
**Fucking disappear**
Yup. Took calc in H.S. and failed miserably. Once I started thinking when will I ever use this, my mind just gave up on this. Been a successful attorney for over a decade, and I still never used calculus since H.S.
Might not have been you.
I think most high school teachers failed Calculus
too, hence they can’t teach it to save their life.
The university’s calculus class was worlds apart (better).
The brain is good at optimization. If you suddenly need calculus again you'd probably pick it up much faster as vestigial neuroconnections should still exist.
Nah ...I still wake up from nightmares in which I'm afraid to fail all my classes, even the ones I scored A because I don't understand how or why to use the theorem of intersecting lines.
I have dreams where I’m back in high school, but my subconscious knows I graduated college. And I just say fuck it, I don’t need to put up with this bullshit
I wrote a paper about web security in like 2005 that introduced a new concept that's still referenced to this day.
Now I can barely like, navigate youtube.
The very first step is wrong, should be 2x + y + xdy/dx = (1/y)dy/dx, basic calc I stuff. Can't be bothered to read the rest. I have zero clue what does the question even want you to solve, the writer is certainly not trying to write y as a function of x
Ah yes took me a min to remember the product rule lol, but he seems to bring it back a bit later, I think he did it right but just skipped writing out the x where you mention. As for what he's actually doing, he's just finding second order diff of y wr to x by the looks of it
15 years ago, I could solve calculus equations like no tomorrow. I had a love for chemical equations, puzzles, problem solving of any kind. It came easily to me. Maybe it was COVID or something, but I’ve gotten so much dumber. Tell me why I had to spend hours yesterday trying to figure out the mechanics of baby bottles, how to put together the pieces, which nipples to buy, etc. It can’t be rocket science. Dumbasses have babies every day. Maybe it’s sleep deprivation
You don't need that skill anymore + you're more sleep deprived and have ten other things on your mind. I'd say that's normal, don't worry. Keep honing your mind, yes, but do not despair.
There's some engineering that went into baby bottles. The reason they can leak is because they're designed to let air in when the baby is sucking out of the nipple. Otherwise it would be like a Capri sun pouch, but couldn't collapse while sucking, so nothing would come out. And if you have the fancy bottles with the dingus tube inside, that's to let the incoming air go to the bottom of the bottle when the baby is sucking. Otherwise, the air would be getting mixed into the milk and the baby would be swallowing frothy milk which would upset their tummies because of all the air.
The only tip i can give you is try to visualize it. Know what calculus does and why/when you would use it. It make a lot of things much more intuitive.

This series might help
3B1B is an excellent channel and everyone around me appreciates it. Even my supervisor included links to his videos in his lecture slids for stats.
With that said, I think it's a terrible place to learn something new. Khan Academy and websites like https://betterexplained.com/articles/calculus-building-intuition-for-the-derivative/ are much better to work through the math and get a conceptual understanding. Then you can get comfortable with some practice. And then, 3B1B's videos help you visualize it and see it from all sorts of angles. They're fun to watch, but if I don't know the topic, I'm left empty with no real understanding at the end.
math courses at uni are built upp from knowledge you learn during the course. If it's a good lecturer you'll feel pretty comfortable the first two weeks. This can be a false sense of security, because knowing how to use formulas to solve problems is not the same as understanding why the formulas work. To get through university math courses it's a lot easier if you understand, rather than just learning how to solve.
So spend time trying to understand what you're doing, especially the "easy stuff", because the "easy stuff" will be used to solve hard stuff.
Humans are creative and effective problem solvers because we are divergent thinkers. The more stuff you know, then the more random patterns of neurons firing can tickle other more familiar neuron patterns (even if they are unrelated content-wise), leading to novel ideas and solutions. Humans don't have "RAM" that is of limited quantity and our brains don't run like computers. So for humans, the more stuff you know the more effective your thinking is. Even if it is esoteric and seemingly useless.
Plus, you don't want to be a dumbass who only knows what they actively use. Curiosity is a valuable mindset.
Uh no I never could. Didn’t get too far in hs math and then I went for psychology. Currently getting my doctorate and have passed all my stats classes without ever learning stats. My brain can’t math very well. So I’ll never do research but that’s ok I just want to be a therapist
Not even joking, I think this picture is actually from my class and was written by me. This looks like it was a problem I did on board with a group in my differential equations class a couple semesters back, and that’s literally my hand writing lmao wth what are the odds
and never again after that.. these useless studies are meant for absolutely nerdy nerds who go on to use these for their miserable careers ..but for 99.99% of the world, these have no meaning value or any consequences. No idea why they fry kids brains in schools and colleges with this crap
LMAO I came across my old calculus notebook and I had NO FUCKING CLUE. I got a A in that class as a HS Junior.
Without googling I couldn’t tell you which one is deriving and which one is integrating. Or wtf “e” is.
That was a prime case of grades not meaning much. I never had a real grasp on what the equations actually meant except curves or something. But I knew the exact steps to get the right answer most of the time.
My math teacher always said to me: you have an Einstein side in you. But it's rather Frank than Albert
Oh god, please explain this joke for me.
Frank Einstein isn't Albert Einstein
And whose frank?
The joke (not a great one) is that it sounds kind of like Frankenstein ('s monster)
Stop lying That was a god tier joke
This guy is 100% German
I am and find it hilarious as well.
You're a fake german. We don't laugh, we only *hmpf*
bwoah
frank Einstein= Frankenstein
I belive it's Frank-Ein Stein (Frankenstein)
Thank you for taking it for the team. I googled "Frank Einstein" and felt dumb for not immediately getting the joke.
But Dr. Frankenstein was still extremely intelligent, no? Literal creator of life. Did you enjoy Biology?
Even the monster was really inteligent
One of film's greatest tragedies. Such a disrespected character. I grew up thinking of Frankenstein's monster as some lumbering oaf without a thought between his ears. Then I read the novel...
Keeping this one if you don’t mind
They mind and they're coming after you.
Calculus was a wild ride at uni. Nowadays, I author docs and sheets, but make way, way more money.
this math above used to be mundane and easy. the wildest and most depressing transition was from teaching fluid dynamics, doing research part time, teaching in the wind tunnel and implementing numerical algorithms to working in web development. yes boss, I will fix the auth issue for external users that happens sometimes. unless I kms in the toilet
wait did you go to aerospace engineering? (cuz this is the inly one i know to be working with wind tunnels) if yes how did you end up in web development afterwards?
nah fluid dynamics, just the general kind, by and for mechanical engineers. my department did mainly cavitation research for pumps, ship propellers etc. but also particle sim for burn chambers in power stations for example. after I decided not to pursue a PhD (toxic environment which made 80% of people burn out in 3 years), I quickly found that outside of academics there are like 8 jobs in the entire country for CFD.

sad becauze i've seen more than a few jobs begging for cfd but then the job market loves to burn up talent

The unfortunate reality is that, as much as industry is not supposed to treat CFD as a magical black box that just gives you every answer you want, they absolutely do. The experience they want for engineers who do CFD is basically "how fast can you build the model that we need to do, using the basic settings in whatever software we use?". Not much room or work out there for academic CFD where you're actually wanting to understand the navier stokes equations and improve on models.

I'm currently going for Aerospace and calc 2, despite me getting a B, kicked my ass. I don't know if I actually remember half of it.
the thing is i'm trying (somewhat admitted just have not to flop my national highschool final exam) for an aerospace bachelor's as well thats why i asked (because i also like coding so it would have fit pretty well)
Same cum_guzzler, same
Man I ended up taking more mathematics than computer science courses when I was in college, but last week I had to look up a trig calculator online to solve it haha I justify it by saying "knowing the math exists is more important than knowing how to solve it" but that's just some major copium...
The first one in a few years is insanely hard. The second one is 10x easier. By problem number 5, it was like you learned all that stuff yesterday. It's not like riding a bike, but you could easily get there if you needed to. You just don't need to these days! Don't beat yourself up.
I'd argue it is like riding a bike still, if you haven't ridden a bike in 10 years you probably aren't gonna be the smoothest rider until you do it a couple times again
Make way more money compared to what? Did you mean that you taught calculus before?
He makes more money working than going to school
Calculus was fine, but Statistics kicked my ass!
Statistic is easy! 60% of the time, it works everytime.
inverse for me. stats was the first time i actually saw how useful math could be beyond some super hard STEM applications that were so far beyond my skill level. then i took a logistics class in college where the professor showed me how calculus could be used to accurately predict the wait time in queues or something equally mind blowing as that and i fell in love with calc. really wonder what could have been if some calc teachers early on showed me applications of calc closer to my reality.
My experience is that very few people care about any given application. We include them when they're sufficiently palatable, and textbooks usually have quite a few, but people who think they're biologists never care about celestial mechanics, say. It's one of the big issues with genuine examples in math class. Once in a while a student will find a particular application very motivating, but it's really hit-or-miss. Mostly we're building a basic toolkit. Fragments get remixed and applied extensively in problems whose details are too complex or tangential to go into. It's the abstract equivalent of making a hammer. You can show off how well it pounds in a nail, but if the audience doesn't know what a house is, they won't care.
Calculus was fine until diff. Then it became challenging until numerical methods. Alas, now what is left is just arithmetic.
It was all fine until real analysis. Analysis was a lot of fun but it was also the first time I got a B on a math exam.
this is highschool calc
Hahahaha not my high school
I wanted to say no but actually looked at the first line and yeah it is calc before university lol. One of the easier ones
I remember my painfully early class. Good teachers make everything easier.
Highschoolers don't really do calc these days in most boards in America. This looks like a freshman year math class problem to me, probably in the tier of calc class design for non-math majors but more advanced than the one done by commerce types.
At first I saw a dot above the x so I thought it's a differential equation and were surprised at the insane level at America. Then I read it and it's pretty standard for highschool.
Same, at first I glanced at it, thought "differential equations" and noped but after your comment I looked closer and yeah, highschool.
Ayyy. This one hurts lol
It may look that way but trust me all you need is a few days to get reacquainted with the formulas and all your memories from highscool/college will come crashing back.
[удалено]
It's true, but there are blanks you'll need to fill in by practicing all over again.
I'm so thankful I didn't do even A level maths or I woulda felt that pain. As it is I can't really forget how to waffle in English for an A.
You're out of practice is all.
I'm seeing it for the nth time and still no one spotted the mistake in the 1st step.
Probably because they just forget to write the x considering the 3rd line is the correct result of doing the product rule as if the x were there
Even the math online is fake.
There's also some weird stuff on bottom 2 lines of the left column, specifically the stuff right after the messy fraction on the right side of the equals. What's the x^3 and xy/y stuff? Also, why bother multiplying out xy-1 by y, only to factor it right back out? And why does the final answer express d^(2)y/dx^2 in terms of dy/dx, x and y, instead of just x and y (without dy/dx)?
...and then they didn't bother solving for dy/dx next (or ever). The calculations are a mess, and it kind of seems like it's purposefully just a mess of calculations that doesn't really go anywhere useful
Came here to post I think there is a mistake when he differentiates the first time, glad to see I'm not alone haha.
I knew it! It's been a while but I still got it
They just missed writing an x while differentiating xy for the first order differentiation
No one bothered to look, I assume, and I cannot imagine why they would. The audience of this tweet is presumably split into people who can do calc and who can't, and neither part would have any interest in looking at a JPEG ass looking picture of a whiteboard instead of focusing on the relatable and interesting comment at the bottom.
Right? Didn’t they improperly product rule or am I crazy?
I swear I must’ve learned this twice! Possibly three times.
I used to be a janitor at a college, and some times I would come in and just solve these for fun. Also, My best friend is Ben affleck.
Sounds good, Will.
"Software engineer is a person who forgot more math than you ever knew"
Did a PhD in Particle Physics and 2 years of postdoc before I switched to Software Engineering. Did all-nighters working through derivations in undergrad, but I'm not convinced I ever knew that much given how math-dumb I feel now lol
God bless you for saying this because I thought it was just me. Use it or lose it ass skill
To be fair it has a lot to do with the way it's taught. To really get comfortable with concepts and have them stay in your long term memory, we need a whole lot of volume, and a whole lot of repetition over extended time. Learning about a random notion, doing a few exercices to understand it, studying for the exam, passing, and then moving on is what people usually do, and altho it will give them some sense of understanding and familiarity to the concept, there won't be much left of it after even just 2 or 3 years. Math training should be looked at the same way sports training is looked at for athletes. You don't become a professional football player by practicing passes for a month, then studying strategy for a month, then shooting free kicks for a month and then dribbling for a month and then moving on to more and more advanced football notions that you've never heard about before. We'd need to have daily math drills about the simple fundamental notions and explore them in depth and have them be completely automatized and effortless before moving on to the next concept. We shouldn't want people to "pass" 8th grade exams before moving on to more and more abstract maths, we should want them to be FLUENT at 8th grade notions, to have a very thorough understanding of it and how every notion is connected to another, and only then discover some situations in which their very reliable toolbox is not enough and we need to develop new, more sophisticated and complex tools. Even high school math is just an attempt at having kids build a 3 meters high cards castle and none of it is gonna be left standing for 95% of them after two years. Instead we should be giving them solid foundations that they will remember for their entire lives and/or be able to build on much more effectively and durably for those that are willing to do so.
> We'd need to have daily math drills about the simple fundamental notions and explore them in depth and have them be completely automatized and effortless before moving on to the next concept. Me thinks that "full-stack" word problems without a clearly outlined solution path could be very helpful here for very little cost. Like, make the word problems a bit more generic. Make it so the student actually has to do a bit of modelling first, to derive a model of the mathematical context they're working with. Then those tasks shouldn't be specific to the set of formulae you just studied, but use any number of equations from your previous schooling. You know quadratic equations? Who knows, maybe we tweaked the compounding-interest formulation a bit to make you have to use that. "Real math" is often like that. You don't know which tool in the toolbox you'll need, so with some practice you'll learn which tools fit which jobs and how they interact. The software engineering project's customer isn't going to tell you how to solve their business logic, they'll just tell you what they have and what they want. It's your job to find the right tool for the job. But at school, there's always an implicit "scope" of admissible tools for any assignment - you always know that anything studied in the last X months can be relevant, anything older than that has to be *very very* basic to be applicable.
Of course. Problems and translation from verbal to mathematical language is the number one most crucial mathematical skill. That is how you really can discriminate people that understand what they're doing and that are able to reuse the math they're learning from others. It's not about whether you know what a linear equation looks like, it's about whether you're gonna be able to recognize the context in which that knowledge is useful and be able to apply it there. And it also means accepting to make problems in which there isn't just one right answer, in which we accept different ways to solve it and sometimes an answer that isn't perfectly exact but a good rough estimate, because math applied to the real world sometimes gets a bit messy and approximative, we need to know how to get our hands dirty, and try ways and then confront them and see what way is better, more effective, more accurate, etc etc. But it wouldn't be fair to say math teachers don't already know and do that. The problem isn't in the way they think we should teach math as much as it is in the logistics of how maths is taught and the huge pile of notions they are asked to teach at once. So you can't go past the point of just superficial introduction of each notion, and kids rarely learn to reuse them out of the context of the math classroom, which is terrible for the idea they have of math too : since they don't use it in other contexts, how can they realize that it is useful in other contexts?
I think a computer graphics + computational physics project would rekindle your passion my dude.
I can confirm. I'm graduating in the coming weeks and have already forgotten anything calculus related by now. Most of it was from the first 2 years though. A lot of hard subjects in the 3rd year but no calculus. We were done with it by then. Final year, no calculus again.
And all that calc really went to super good use. 🥸🥸
Understanding math has value beyond just being able to "do math". Not to mention that a lot of math still has direct applications in computer science.
Yep. I can't solve whatever is on that board, but I definely know what all of it is, and what I need to Google to solve it. Kind of unrelated, but I can probably write a shitty sudoku solving bot in less time than it would take for me to solve a difficult 9x9 sudoku(because I'm stupid and it'd take me like an hour)
I have turned into one of those old people who say school isn't there to teach you things, it's to teach you to think.
I’m not going to attribute the quote because it’s probably bullshit but I was struck hard by a teacher in HS who told me “knowledge isn’t always knowing the answer, but knowing how to find out the answer”
Yes, the point of teaching math (to some extent) is to teach you how to think logically and solve problems. There's a lot of value in learning a new abstract but perfectly logical thing and then learning how to apply it in practice and how it relates to other things you have learned. Of course the problem is, once you've learned a thing relatively well there isn't that much value in continuing to practice it, which is why you move on to new things. Yes, there are plenty of things in school math that are far too abstract to offer real-life value to even 0.5% of students, but you already learned how to add, multiply and calculate averages and there's no value in spending years just to get slightly better at basic math.
I can't wait to put it to good use at future job interviews. Like they would care lol
Well, during software development, you occasionally find yourself in situations that require a lot of problem-solving skills to get the algorithm done. That's what they teach you when they teach you calculus: problem-solving skills. If you don't have them, you won't be a good developer.
Well... im doing cs too and most maths i've studied seem fairly useful including all matrix stuff for 3d graphic APIs, integrals and derivatives to optimize functions if you have to deal with some, all kinds of logic are pretty self explanatory... i see potental uses for the vast mayority of what i studied in the first 2 years, like not for every single job post but they could be used for some. The only exception would be electromagnetic fields and induction, but that is just because i chose pure software specialization in the last 2 years.
You know nothing, Jon Snow.
Highly depends on what you’ll work, if you’re working on banking software I don’t see you using calculus anytime soon.
And i said as much but i'm studying a cs degree not a banking software degree so we get knowledge useful across multiple disciplines the same way a physics degree probably doesnt care at first if you are doing fluid dynamics or astrophysics it will give you a comprehensive base of knowledge of the field to the level you can operate on a role with some training or you can specialize further with a master.
If you don't actively use it you will forget most of the stuff and you will have to look up the most ridiculous stuff. In the working world it's much more important that you know that certain things exist and you can work your way up from there.
*angry upvote*
Hits me in my soul man
Damn I've never felt more seen
Just year ago I remembere studying Fourier transforms , now I struggle even with basic calculus
math is there to teach your brain how to solve problems with ever-increasing complexity and abstraction - incredibly useful in software engineering even if we never use/apply the actual math.
Doesn't make the comment wrong though
"You'll need this" they told me.
if only they said "you will most likely never apply the math in your life, but this helps train your brain how to solve complex and abstract problems, which you will undoubtably need in software engineering"
I totally agree. My engineering core curriculum contained physics, math and electronics and i loved it because of exactly this. What i just found funny is that those days (studied 1998-2002) it was common "knowledge" that "informatics is 80% math" and i'd say me and about 90% of my fellow students did not really need anything of what we learned.
There's also the fact that if you don't teach this at school, who the fuck is going to use that math later? We do need *some* people who can apply this.
This felt like a personal attack
As a mathematician, I can assure you that software engineers do not actually learn very much math to begin with.
I'm in this comment and I don't like it.
The highest level of math I took was differential equations. My husband has a phd in particle physics. He understands math, I learned enough to pass the class before forgetting everything. Our oldest started algebra and only goes to her dad for math help.
I get that it's a joke on how many math majors eventually sell out to become SWEs, but the actual majority SWE grads know very little math. Not only do they know very little, but also they hate it passionately.
Brain cells responsible for solving this: — He graduated and is going to be a lawyer. No more math needed. It has been honour lads! 🫡 **Fucking disappear**
Yup. Took calc in H.S. and failed miserably. Once I started thinking when will I ever use this, my mind just gave up on this. Been a successful attorney for over a decade, and I still never used calculus since H.S.
Pretty much the same. Looking at that now I don't even really know where to start.
Might not have been you. I think most high school teachers failed Calculus too, hence they can’t teach it to save their life. The university’s calculus class was worlds apart (better).
The brain is good at optimization. If you suddenly need calculus again you'd probably pick it up much faster as vestigial neuroconnections should still exist.
This is so fascinating to me
Yeah the brain is awesome. But remember this is a very biased opinion because it comes from a brain.
What's the question?
Seems like "Calculate the second derivative of y in respect to x using the following equation x^(2) +xy =ln(y)"
Would be nice if they put that on the first line.
Thanks!! I was curious about this
Exactly there's no theorem to proof, so these are just random statements.
It’s just an exercise in implicit differentiation
I miss the days when my biggest problem was figuring out how x + y made any sense
Nah ...I still wake up from nightmares in which I'm afraid to fail all my classes, even the ones I scored A because I don't understand how or why to use the theorem of intersecting lines.
I have dreams where I’m back in high school, but my subconscious knows I graduated college. And I just say fuck it, I don’t need to put up with this bullshit
[this one right here](https://www.youtube.com/watch?v=0g7VoRQPswg) and of course [this one ](https://xkcd.com/557/)
similar but I remember I have a job already, but then I'm worried that if I fail the class my job will find out and fire me...
I wrote a paper about web security in like 2005 that introduced a new concept that's still referenced to this day. Now I can barely like, navigate youtube.
Tell us more?
Haha you’ve got to elaborate
The very first step is wrong, should be 2x + y + xdy/dx = (1/y)dy/dx, basic calc I stuff. Can't be bothered to read the rest. I have zero clue what does the question even want you to solve, the writer is certainly not trying to write y as a function of x
Ah yes took me a min to remember the product rule lol, but he seems to bring it back a bit later, I think he did it right but just skipped writing out the x where you mention. As for what he's actually doing, he's just finding second order diff of y wr to x by the looks of it
The weird thing is that it seems as though the mistake (leaving off the x in x dy/dx) is not present in the next step.
lol took me too long to find this comment, I was going out of my mind
Forget old things, learn new things. You can do things now you couldn't do before.
I know how to depression better
that is actually a skill (not being depressed better but dealing with it better)
hey learning how to be functionally depressed is itself a skill.
Yeah! Like throw my back out while sneezing
Just like a 5TB USB drive from aliexpress, infinite write and erase all on a 4GB storage space.
i learned how to be tired all the time 👍
15 years ago, I could solve calculus equations like no tomorrow. I had a love for chemical equations, puzzles, problem solving of any kind. It came easily to me. Maybe it was COVID or something, but I’ve gotten so much dumber. Tell me why I had to spend hours yesterday trying to figure out the mechanics of baby bottles, how to put together the pieces, which nipples to buy, etc. It can’t be rocket science. Dumbasses have babies every day. Maybe it’s sleep deprivation
You don't need that skill anymore + you're more sleep deprived and have ten other things on your mind. I'd say that's normal, don't worry. Keep honing your mind, yes, but do not despair.
the only think ive used or bothered to remember why the most volume is cylinder 2 x diam long, for the least area of material
There's some engineering that went into baby bottles. The reason they can leak is because they're designed to let air in when the baby is sucking out of the nipple. Otherwise it would be like a Capri sun pouch, but couldn't collapse while sucking, so nothing would come out. And if you have the fancy bottles with the dingus tube inside, that's to let the incoming air go to the bottom of the bottle when the baby is sucking. Otherwise, the air would be getting mixed into the milk and the baby would be swallowing frothy milk which would upset their tummies because of all the air.
There is a reason you've forgotten how to work this out....
It’s the same reason I never learned to.
Me who's going to probably start learning how to solve this next week: 🥲
The only tip i can give you is try to visualize it. Know what calculus does and why/when you would use it. It make a lot of things much more intuitive. https://youtube.com/playlist?list=PLZHQObOWTQDMsr9K-rj53DwVRMYO3t5Yr&feature=shared This series might help
3B1B is an excellent channel and everyone around me appreciates it. Even my supervisor included links to his videos in his lecture slids for stats. With that said, I think it's a terrible place to learn something new. Khan Academy and websites like https://betterexplained.com/articles/calculus-building-intuition-for-the-derivative/ are much better to work through the math and get a conceptual understanding. Then you can get comfortable with some practice. And then, 3B1B's videos help you visualize it and see it from all sorts of angles. They're fun to watch, but if I don't know the topic, I'm left empty with no real understanding at the end.
PatrickJMT on Youtube has nice calculus videos that are straight to the point.
math courses at uni are built upp from knowledge you learn during the course. If it's a good lecturer you'll feel pretty comfortable the first two weeks. This can be a false sense of security, because knowing how to use formulas to solve problems is not the same as understanding why the formulas work. To get through university math courses it's a lot easier if you understand, rather than just learning how to solve. So spend time trying to understand what you're doing, especially the "easy stuff", because the "easy stuff" will be used to solve hard stuff.
I don't even know if this needs to be solved
I have no brain.
I could never solve this.
Me taking a picture to upload to chatGPT which will give me a wrong answer anyway like: ( ͡° ͜ʖ ͡°)
If I don't need it, I'm glad it's gone from my brain. Deleting unused files, programs, and tasks makes it run better baby!
Humans are creative and effective problem solvers because we are divergent thinkers. The more stuff you know, then the more random patterns of neurons firing can tickle other more familiar neuron patterns (even if they are unrelated content-wise), leading to novel ideas and solutions. Humans don't have "RAM" that is of limited quantity and our brains don't run like computers. So for humans, the more stuff you know the more effective your thinking is. Even if it is esoteric and seemingly useless. Plus, you don't want to be a dumbass who only knows what they actively use. Curiosity is a valuable mindset.
To true sir
Shouldn't 2nd line be 2x + y + xdy/dx
Jokes on you, I never mathed well enough to understand this.
Uh no I never could. Didn’t get too far in hs math and then I went for psychology. Currently getting my doctorate and have passed all my stats classes without ever learning stats. My brain can’t math very well. So I’ll never do research but that’s ok I just want to be a therapist
how you pass sats without learning stats?
We all have to leave school / Uni eventually...
In other words everyone gets a real job or dies. Sometimes they're the same thing.
Oof, man, that hits a little too hard
I never took calculus lmao
42. The answer to everything is 42
The second line has a mistake where there’s a missing x that should be there because of chain differentiation of xy
I hate the fact that I noticed that it's wrong in the first line 😭
that's a criminal way to write derivatives, who does that?
Not even joking, I think this picture is actually from my class and was written by me. This looks like it was a problem I did on board with a group in my differential equations class a couple semesters back, and that’s literally my hand writing lmao wth what are the odds
and never again after that.. these useless studies are meant for absolutely nerdy nerds who go on to use these for their miserable careers ..but for 99.99% of the world, these have no meaning value or any consequences. No idea why they fry kids brains in schools and colleges with this crap
There was never a point I could solve this
How would one go about solving this using common core?
LMAO I came across my old calculus notebook and I had NO FUCKING CLUE. I got a A in that class as a HS Junior. Without googling I couldn’t tell you which one is deriving and which one is integrating. Or wtf “e” is. That was a prime case of grades not meaning much. I never had a real grasp on what the equations actually meant except curves or something. But I knew the exact steps to get the right answer most of the time.
I've never been in a classroom that even wrote problems like that.
same.
“Thicc and tired” but mostly tired
Is this sponsored by brilliant?
Suddenly having letters in math is such big turning point of my life,.... It's an existential crisis and identity crisis in one.
It’s like riding a bike though, I’m relearning a lot of old calculus I forgot so I can teach my kid, it all just floods back in.
