How Much Math Do Engineers REALLY Use??

[@c.howard9413]

I do agree with the claim that typical engineers do not do too much math in industry. To some that will be great, but to others that might be disappointing. For those who might feel disappointed hearing that, there do exist jobs that flex more on the math side of things. In my case as an aerospace engineer, I worked in defense doing guidance, navigation, and control algorithms and I did advanced math daily. Lots of differential equations, optimal control, calculus of variations, numerical algorithms, machine learning, etc. So there does exist some options that use math a lot if you want that, you just need to try and find them!

[@c.howard9413]

@@WissamSeif I think your message was fine and definitely is a good representation to how the typical engineering job will go, eg. complex math is done with software (like FEM packages) but the engineers should (hopefully) understand how those things work so they can use them properly. I personally worked mostly on missile guidance and estimators, with a little time spent building simulation related code, and so lots of the more advanced math I did was related to that. Sometimes we used variational game theory approaches to formulate optimal missile policies under the assumption of an optimally maneuvering target, so these sorts of tasks required working things out by hand based on (simplified) models of our system. Sometimes we would need to formulate numerical algorithms for more complicated versions of these problems which would lead to lots of numerical optimization work by hand before implementing things in software. For example, I used numerical techniques once to work out an optimal control algorithm that could get two missiles launched separately to impact at the same location and at the same time (a tough problem!). Those are just two examples but my team and I used pretty advanced math all the time and I really liked that about the job.

hi!!! ive always wanted to go into a maths heavy career, so what other (engineering) options r there? u've already mentioned aerospace engineering, but what else is there? another question, on a typical day, what does an aerospace engineer do?

[@c.howard9413]

@@zee6726 I would argue every field of engineering has the potential for having a math heavy job, though finding them and obtaining them may be tough. Research oriented jobs tend to be more math heavy but getting them usually requires a graduate education, potentially up through a PhD. To your last question, this ultimately depends on the job of the person. For me, my typical day was along the lines of: - Get to work and pass through the various levels of security until I got to my desk in a classified lab - Check emails and refresh myself on what tasks I should be prioritizing - Start working on the list of tasks I have. Some of these tasks required working out a bit of math on paper for a bit and then writing algorithms based on the math in software. Some tasks required processing a culmination of data to understand the performance of a missile that was fire. Some tasks required doing some distributed computing to generate data or optimize some aspect of our missile. This is only a sample of what the tasks could look like as there was a bit of variety. - After doing a bit of work, I sometimes take a break to work on some software tool that I felt would help my team. An example of this was I built a distributed optimization framework that could take any objective function and use a variety of heuristic methods like particle swarm optimization (PSO) to optimize the function in a parallel manner. I used this to optimize our bayesian estimator for our missile and achieve much better than human-tuned performance. - Lunch and take a walk - I get back to working on the list of tasks, maybe having meetings at some points or needing to present something to the military - Finish work, head out of my lab, and enjoy the rest of my day doing non-work related things As you can see, my day is structured in a similar way to probably most people but it was just the types of things I worked on tended to be different!

[@pythagrates]

I love math but I think Math Classes spend too much time on testing your ability to remember equations, and not nearly enough time discussing what the answers you get actually mean and why you should care about them. Being able to analyze and understand the answers is way more important than remembering 100+ equations you'll forget within a year of finishing the class.

[@AtomicVertigo_Comics]

thank you, yes. i am currently in engineering school, and i feel this is too important to be overlooked. im good at math, because i can memorize equations. what im not good at, is know what the equations mean or what they help you solve for. it feels really icky that i have to turn to youtube just to know WHY im learning what i am in my college courses.

[@CalebRyals]

I get what you're saying and I dont disagree to an extent, but technically what you're asking of math what is meant to come from physics. Your answers in math are abstract and arbitrary and essentially have no deeper purpose than merely existing as a solution to a process that's built on rigor and a sense of clinical, detached exactness. The 100+ equations you memorize, or rather the definition and defense of the processes behind them, are the purpose of math itself, not applicability.

[@abdoonyt9049]

So, in simple words: pay attention

[@RangersGirlJackie99]

The problem with the "math classes" engineers take is that they're very low level stuff like calculus. You can't truly explain calculus rigorously (real analysis) without a strong basis in group theory, fields, set theory, some topology, and just general proofwriting. Even the most advanced concept in calculus III is handwaving "trust me that this works, just remember this formula" stuff compared to the first week of an undergraduate intro to real analysis course. Real analysis is the process of building a rigorous understanding of how the reals behave from the most fundamental axioms upwards, and even those fundamental axioms would probably fly right over 99.999% of people's heads -- enough people get weeded out by baby calculus already, no need to make it any more difficult if all you're going to use it for is application fields.

Great discussion. I graduated BSME back in '82 and have used calculus twice and PDE once and a whole boatload of plain and matrix algebra. Your casing hanger problem was one of the first things I started working on around 1985. We used Belleville washers to overcome the near constant load problem (this is useful for varying temperatures and packer hardness). We used paper and pen and had to be real careful not to make little errors. The current equation solvers and FEA programs make this all very easy and productive. The current programs make engineering much more fun and accurate. Try getting the mass and CG of a 2000 piece assembly back in 1982. You would be doing that for a week, now it takes 5 seconds. My favorites are aero and hydrodynamic flow FEA programs.

[@phitsf5475]

I haven't watched the video but I feel the need to chime in with opinions, answering simply to the video title, "How Much Math Do Engineers REALLY Use??" Engineers will use their math experience CONSTANTLY, it just won't be in the obvious formalised format found in the exams they studied hard for. Simply having completed the work behind studying for and ultimately doing exams will have burned itself into an engineer's brain. The concept of an integral or derivative doesn't get forgotten in the same way as the specific steps required to solve textbook problems; That concept lives on in their heads whether they are conscious of it or not. Rates of change exist and problems are rarely static, simply knowing this is enough to change the way you approach problems. While they likely won't take a week to do a bunch of maths by themselves, they will recognise when a problem requires a certain level of deeper thinking and they would be wiser to pass the problem onto someone else. I think this is a good thing.

I teach calculus at the University of Buenos Aires, Argentina. Here, we have virtual lessons since the beginning of the covid pandemia. And other colleges and I are making an experiment: instead of forbidding the help of technology, we encourage their use. We think the replacement of hand-made calculations with online calculators could be very positive, in terms to achieve a more profound understanding of the core of the concepts, without wasting time in calculation techniques.

[@euyin77]

@@WissamSeif That depends. For example, you won't learn integration better if you solve integrals by simple fractions decomposition with 4 or 5 terms instead of two terms. Or if you calculate a very long derivate. Or making 3 or 4 steps of Runge-Kutta by hand instead of doing it with excel or python. Obviously, the evaluation process needs to change. It has to be focused more on the concept than calculation. And that´s hard for many lazy professors. I also teach precalculus for admission at Universidad Tecnológica Nacional (Our top university in engineering) and we are aware that students can use technology in virtual exams. So we decided to guide them and help them with that.

And for example in wireless communications, we would like to be able to send information faster and this requires more clever encoding and decoding algorithms of information , and in order to come up with new ones (if you have an R&D job in a place like apple or Samsung for example) you have to derive math equations that represent or sometimes even invent new algorithms to achieve such a goal.

From my own experience so far, I've used iterative root-finding algorithms, fair bit of curve fitting to create surrogate models (tends to get a bit creative for funky multi-dimensional data), transforms for converting between different coordinate frames of reference, vector-matrix operations, some basic statistical analysis, and had to brush up on comprehending quaternions. Bit of a variety of different tasks/projects, but very satisfying to be able to apply so much of what I learned (& taught) and to learn and apply concepts beyond what I ever studied. Really depends on the field and the type/stage of business though. If I worked at a massive well-established engineering giant, I suppose I'd rarely do much outside of using common engineering software packages and picking through spreadsheets.

[@robertfennis6088]

If you are truly employed as an engineer, and by that i dont mean truly in a gatekeeping way but more so in a not manager type way, you should know your math.

[@federicopelizza9563]

This will probably be lost in the comments, but I think that it is much more important to understand the underlying principle and the way the numerical solution works than to find a rigorous analytical solution to very simple problems. This due to the fact that once the problem gets hard enough you won't get an analytical solution anymore or it's not worth it to spend the time to obtain it. don't get me wrong, the analytical solution to a simplified is indeed useful, but only as a very rough estimate for comparison purposes.

I have used math constantly over my 39 year engineering career. My focus has mostly been on electronics and software for autonomous mobility (incorporating AI), and many years of military vehicles and robot sw in the defense industry, so maybe I'm an odd case. As an example, the other day I was working out the partial derivatives (Jacobians) for a Kalman filter. I use trig constantly for translating between multiple coordinate systems used in physical systems. It is quite apparent that many of my engineering coworkers often don't have a clue about the math I'm doing. I see their eyes glaze over in my presentations, but perhaps that's why I'm a top engineer most places I go. I constantly had to work out battle damage calculations and equations of motion for projectiles, quite frequently, while working on defense systems.

[@jp-hh9xq]

@@WissamSeif First I had to study the physical tests/experiments that had been performed with real military projectiles and vehicles, with detailed damage metrics taken, with regard to damage caused by various projectiles that hit at various points and angles on the vehicle. I could classify different bounding boxes on and around the vehicle, that if hit with a projectile of a certain type, different damage would occur at each rough location, and at different angles. This is usually some floating point number that represents a damage percentage. I can't say a lot about that without exposing IP, but I can say that 'spall' and the placement of critical systems is a major consideration. This was all done in a 3D simulation environment with 6DOF motion simulators. Man that was a very fun time as an engineer. We developed all of that from scratch over years. So I knew I needed a data structure that would allow me to break up the vehicle into an multi-dimensional array of battle damage percentages based on where and at what angle, and of what type, would cause a certain amount of damage. Then, using trig, you build an overall bounding box, so anything outside of it get's ignored. Anyway, anything about where is best to hit a vehicle or anything like that is strictly classified and I would never consider getting into that kind of thing. Most modern video game engines do all the work for you now, so much so that they are used across the industry. No sense in creating a framework for it from scratch, like we did back then! Sorry, I'm off topic. As for math, well a lot of knowledge trig is very good to do cheap and efficient checks. Always start with broad checks, and narrow down and down until you do that final calcs of actual damage on only relevant interactions. The projectile might hit the ground near to the vehicle, and still do damage. So a lot of trig is very important to work out of the physics of it all. I like, and regularly use, law of sins, law of cosines, heron's formula, cross products, dot products, linear algebra. Also a formula as simple as Pythagoras theorem, can be applied in many interesting ways. One is: Everyone knows that A^2 + B^2 = C^2, but if you express a line in standard form (Ax + By + C = 0), not slope/intercept, and plug in a point for x and y, that A^2 + B^2 > C^2 vs less than C^2, then one can determine if the point is left or right of the line. In standard form, the line is more of a vector because it has a direction vs in slope/intercept it has no direction. There is a ton of tricks like that to check bounds very quickly. Edit to add: As far as hand-calcs, only drawing diagrams to get the math right and a couple spot checks, as when the computer does millions of calcs to make decisions, it's obvious pretty quickly that the calcs are wrong. Most multi-dimensional lookup tables are used as confidences based on empirical data.

Got to tell the truth to viewers. How much math do engineers really use? My answer is ALL THE MATH. Starting from Algebra up to how good engineer you want to be. How you are supposed to use CAD (p.s) if you don't understand Trig. How you are supposed to give any kind of input to computer if you don't understand how to look and understand geometric shapes and master calculus. Long story short. Math is not about solving equations but to develop the analytical thinking and problem solving. If you don't understand math, you are not a problem solver. Not a problem solver = not an engineer. So, you better go and learn that math. All of it!

[@seanriopel3132]

I missed the word "math" in the title, so I read how much to engineers actually use? And I was a lot. Smart people tend to use. 😂

[@BarriosGroupie]

Yes, but engineers are being hired in the belief that the work is too easy for them to make stupid mistakes, and can get quickly up to speed in a week. Whereas hiring someone bright but without the engineering background might take months in comparison and then having to deal with their mistakes.

Hello physicist here I'm here to comment π = 3 lol

So you’re telling me we are learning matrices just for FEA software to do it themselves 🗿

How much math do engineers study? Not a lot. How much math do engineers use? Very few, in average. (I'm a mathematician)

[@rolandotillit2867]

Math in engineering, is basically just ratios and relationships.

[@SaranaeJang]

Math is useful eventhough you never use it.

[@Lemurai]

Some of the worst math I encountered was in my chemistry minor, while doing Chem E, PCHEM is a weed out course of the highest order for Chem students, and I can honestly say it’ll give an engineer a run for their money, it was a god awful class.

[@david14402]

So all the tiring math they force us to learn from high school and beyond comes down to the push of a button? 🤦‍♂️ So why bother everyone like that? I just do not understand. Something here does not make sense

[@jp-hh9xq]

Well first you may have to model a complex physical system into a computer using the equations you have learned. Then you push a button and it does all the math in real time. It's not like you're getting out a blue book and working the equations down to the final answer. But you have to understand how and why the equations actually work, to model a system using them, before that 'button' can be pushed. Does that make sense? That's why you have to work through them painfully, at least once in your life, or you wouldn't even know what equations to start using to solve a problem.

Lmao the right answer is just... Excel :v

[@sebvv5219]

PI=3 that's it.

[@zaid7407]

I'm watching this instead of practicing for my calculus test😂

[@harrison1675]

Disagree, DSP engineers use a ton of math on the job. Maybe not hand calculations but if you don’t understand the math you are implementing into the computer, you might as well be throwing shit at a wall. Don’t speak for all disciplines, Electrical ain’t Mechanical.

[@harrison1675]

You guys mainly deal in free body diagrams, of course you guys don’t need a ton of math for that.

Doing math??? That’s what Matlab was made for 😂

[@TheBalancePod]

None.

[@eleven3426]

Do engineers use math?!?

[@jp-hh9xq]

Read the comments and you'll see that many of us do, but a lot of people are also just mindless drones that push paper, manage bills of materials or people. If that's what you want to do, then no, you won't use much more than arithmetic done by a spreadsheet. On the other hand, if you want to work in R&D and design a state of the art real-time control system, you may use a ton of higher math. I prefer the positions of the later variety. I know a lot of people who went to school for engineering, and graduated, but knew deep down they were no good at it. There are many positions for trainers, sales people, project managers, and other that will never work an equation a single day in their careers and are paid very well.

[@oscarobioha595]

I like how engineers think they do 'complex math' what a joke. Hell economists do more real maths than engineers

[@rolandotillit2867]

Most engineers are just software operators.
