Aerospace engineers build missiles. Electrical engineers build guidance systems. Civil engineers build targets.

I'd like to formally apologise for the number of times I said the word Engineering 🤣

My toxic trait is to think that once I understand math and physics I can conquer everything

The fun thing about being an engineer is that multidisciplinary knowledge is as valuable, or sometimes even more valuable, then specialized knowledge. I, for instance, am a civil engineer specialized in structural engineering. But I work for an oil company as a software engineer, writing software that deals with structures of oil rigs and ships. I don't know about ships as marine engineers do, about oil rigs as petroleum engineers do, about software as software engineers do, but knowing a decent amount about all those areas got me a really good job.

My natural tendency is to come here to say something sarcastic about engineers but I’ll be serious for a change. My grandfather was a district (civil) engineer in India. I was really close to him but he died when I was young. Years later I went to see a bridge, the construction of which he led (I also broke Indian law by taking a photograph lol). I remember thinking how amazing it was that that bridge outlived him and will outlive me. This monument to him and his team had helped god knows how many thousands of people. Not many jobs let you leave such huge legacies. So much work in this video, amazing stuff.

This video has reminded me of no matter how well versed I am in my Electrical Engineering field, I am an expert of only a small portion of the whole Engineering map

I really love what you said at the end about engineers having the "engineering mindset". I have a degree in Mechatronics and are currently getting a degree in Aerospace engineering, and the one true red string through both of them is what was taught to me at the very beginning of my studies: engineers are problem solvers. We try to analyse, structure, divide, test, iterate and solve given problems for the benefit of everyone. In order to do so, there is no "best engineering discipline", every situation requires different sets of skills and knowledge, and also like you said, ingenuity. Interdisciplinary knowledge is a very great asset in that regard. I believe having the engineering mindset just means, that you are not afraid to approach problems in a systematic way and work towards a solution, which very often involves teaching yourself new skills.

I was reading all the comments, and I see that almost everyone is some kind of engineer. I am not - I'm a performing musician and a personal trainer. But I loved this video. I am very curious about all kinds of things - physics, natural sciences, math, biology, etc. In order to become certified as a personal trainer I had to learn a lot about the inner workings of our body - bones, musculature, chemical processes.and so on. Your videos are just wonderful and give me insights into so many other topics. Thank you so much!

one thing i have noticed about engineering is how multidisciplinary the whole field is. My personal interests lie in thermal properties and the movement of energy, so I'm a mechanical engineer and i specifically like refrigeration cycles (AC, HVAC, refrigeration). Within that field, we have mechanical engineers that work in several areas that cross over into other disciplines. we have controls engineers that tune our controlled devices to get the desired thermal properties, we have software engineers designing predictive software to determine system behavior, and we have materials experts that know the properties of refrigerants inside and out. All of these people are Mechanical engineers in this case, but do interdisciplinary work at the crossover between 2 disciplines. its fascinating. Also, I'm glad you said mechanical is about energy conversion. throughout my schooling, everyone, including other MEs, would think i was crazy for saying that because they only focused on solid mechanics and couldn't recognize that that, too, is a energy related process.

These maps remind me there are experts in each of these fields who have forgotten more about the subject than I will ever hope to know. When I become tempted to reject the counsel of experts, I will remind myself that I can almost always trust the consensus [of] experts to help me choose a path for myself. Thank you for another awesome video.

i am a computer engineering student and i used to complain about some of the subjects like applied mechanics and thermodynamics because at that time, i thought they were irrelevant to computer engineering degree but thanks to your video, now i understand that all the disciplines of engineering are related.

I'm studying mechatronics engineering, and when the part about mechanical engineering comes in, I started to cry because I noticed again why I was studying this major and why I wanted to be an engineer: I really wanted to help people with their lives and make life easier, more accessible, and more efficient for people around the globe. Build stuff to help us. I haven't decided which specification I want to specialize in yet, but in these hard times, I'm glad I chose this path. To all engineers and engineering students, I respect you in that way. Let's make our world, with the power of science, bright, shining, peaceful, and painless! Not only for money, we shouldn't be smart minds under the control of capitalism. Don't forget why you chose to be an engineer! Never, even in the darkest of times. love from a future engineer!

Network Engineering?! Hey! That's me!! I suffer from imposter syndrome so being represented here is awesomely validating. Seeing all of the other fields represented here also helps bring into perspective how not-simple and not-obvious the problems in my field can be to solve. Very cool video! Love it as always!

I greatly appreciate your efforts in making all these maps

I feel like a Map of Finance/Economics would make a great video too. Its a very vast subject and I would like to see the nitty-gritties of it.

please keep doing these, our world needs more understanding of science in all matters 👏

I read a great popsci book on engineering last year called Structures and was stoked at the chapter dedicated to the properties of textiles. I was working in heavy duty textile manufacturing at the time and had an "oh duh" moment when i realised that the author of the book was a naval engineer, and one of the biggest clients we had at the factory was the australian navy - another one of those interdisciplinary things that was so obvious in hindsight! A funny thing the book mentioned was that in the 1920s or so a huge breakthrough was made in sail efficiency (re-orienting the fabric's bias with regards to the mast) but that breakthrough came from a Madeleine Vionnet, a fashion designer who created the bias cut dress

The one change I would make would be to move the power grid into electrical engineering, while it certainly does branch off into other domains of engineering at its core it is electrical engineering. In fact power is probably the oldest form of electrical engineering. Eventually electrical engineers figured out how to harness electricity to do other useful things but originally it was all about power distribution enabling the decoupling of power generation from power consumption.

I would love to get a map of Aerospace Engineering!

Totally appreciate the efforts to compress engineering into 20 min or so and doing it so perfectly.

I love this channel. The roadmaps are great to provide a gist of an entire field. As an applied maths major, this is quite helpul when it comes to gaining insights about other domains.

As a civil/structural engineer, I loved this video. And I have a huge passion for computers which leads into electrical, and tons of other fields, and you nailed everything here. Amazing vid!

My son’s an electrical engineer and I understand his work a teeny bit better after watching this. I love these maps! They are cool to look at and the information is explained and described beautifully. Thank you!

This video is just incredible! I'm an electrical engineer and a particle physicist who works at CERN. I can say that most of the subjects you covered in this video are things we need to know to work there. :)

I have recently subscribed to your channel and I was amazed to watch such mind boggling videos.Thankyou you for giving us clear understanding of every popular field

I can’t thank you enough for this video!!! I’m a computer scientist that’s always been passionate about understanding how things work. I’ve wanted to pursue engineering but feel like I can’t decide between electrical and mechanical. It’s just been so overwhelming trying to pin point a path when I keep learning about topics and see how they connect but feel like I’m deluding myself thinking it’s all data that I can utilize.

I think this is a great map! I am currently a biomedical engineering student who switched into this major recently, and I’m honestly loving how practical and useful and interdisciplinary all of the engineering fields are. I definitely appreciate the depth of knowledge used for all of the products made from engineering.

Just started computational engineering college a week ago; love this map!

I am a Metallurgical and Materials engineer, we are kind of a bridge between physics and engineering where we try to develop the materials for the engineered goods and structures.

Great overview and content. The map itself is well organized, but we have to give props to the small illustrations. They are amazing... simple enough, clear, have nice composition and are definitely well researched!

As an acoustical engineering student, I loved the spot you used the field. Electronic related courses, are predominant in my degree. I have a friend who studies electronic engineering and we found ourselves frequently surprised from the programs similarities (this is taken into account exceptions like acoustical measurements and instruments which are exclusive, and many others). Great video !

What a great video to demonstrate the wide range of career paths a young engineer can take. As you might expect, the team here at ANR believes that being a precision engineer is a most exciting and rewarding career. For many years we have run regular apprenticeship programmes. These courses always reaffirm to us how young people appreciate the importance and scope of engineering across every field of industry, and in all walks of daily life. This video confirms our belief that engineering is a great career for anyone to start and there are many specialist areas for budding engineers to work in.

Love your maps. I shed a tear when you specifically mentioned mining without mining engineering, though.

Thanks for all the effort and research that went into this🎉👍🏿

I appreciate you for doing this work of gathering information and expressing in such an eloquent way.

As a first year electrical engineering student, this is very useful for choosing elective courses!

I absolutely love the contents of this channel. Could you also make a map of life sciences or map of diseases? It would be incredibly valuable to see the big picture :) Cheers!

One of the best, most organized, informative channel there is It even helped on career vocation

This is absolutely amazing, I'm sure it took a lot of work and research. I do a lot of STEM discussions for students I will definitely reference this material. Thank you so much!

Awesome map/video and I can tell there is a ton of effort that went into this. Was waiting to hear embedded systems engineering mentioned as it’s the true bridge from electrical to computer, though it certainly can fall right under computer engineering and maybe was too specific of a field. Good video!

For those who didn't quite understand industrial engineering as it was only touched upon very briefly: Industrial engineering could be simply explained as more of a general engineering field focussed on the optimization of complex systems. How do we optimize flows in a factory? How do we prioritize? How do we create supply chains that are cost-effective, efficient and robust? Industrial engineering is huge and an integral part when it comes to producing and moving things and is basically the discipline that takes into account how we move information, goods, money, and other things through a system, physically and digitally. An example is the automotive production line. We're dealing with vast numbers and varieties of supplier parts coming in to one spot to be assembled. The factory needs to be set up in an optimized way, the internal logistics needs to function well to minimize down-time, and nowadays we are focusing more and more on external systems or entire supply chains and optimizing them. In industrial engineering we say that companies are no longer competing with other companies. Supply chains are competing with other supply chains. This is very complex and requires an engineer that is more of a generalist and has his or her hand in many cookie jars. Everything from economics and negotiations, to production engineering and supply chains.

Very grateful this channel exists. Excellent use of engineering knowledge for the content, and art knowledge for the visual.

This has got to be one of the best explorations of the surface layers of all these beautiful different fields of engineering. A unique display, thank you so much for your research!

Society needs more people like you

Great video, i just started mechanical engineering, i hope i can work hard and achieve a positive impact for the world. Love from Indonesia

Love to see systems engineering represented, despite degrees in mechanical and aerospace I find myself working as a systems engineer now, so its nice to have some recognition :)

Excellent video. I truly enjoyed you walking me through the vastness that is Engineering. It will certainly help future students (or interested parties) understand which space suits their preferences best while also realizing how important it is to recognize the interconnectedness of all these areas in the real world.

You deliver excellent content to your audience. It's very interesting material. All of your effort put into creating this video is much appreciated. I'm truly grateful for your help!

Finally I have some peace of mind thought you were not going to upload any video but kept hoping you upload and finally ♥️

Nice summary. So few people understand this. When I was a little boy, I wanted to be an engineer. But the kind that drives a train. I ended up an Electrical Engineer.

This video was awesome I learned so much, I have gained a deeper understanding and appreciation for this field. I wish I had enough grit to enter world of engineering and to help build something awesome but it is what it is. Shout out to all the engineers making it happen!!

Thank you for organising for me this disorganised world and making it sensible in a realistic way. This is a more practical way to why I studied cause I was always so confused in what I was studying

The electrical engineering topic misses one very important topic: Antennas and electromagnetic radiation. Also if you mention auto equipment, you also have to talk about imaging tools and displays

Great to see another map from you, and from Clifton too 😃

very nice and clean presentation of such a complex concept, well done! also i'm a new graduate from materials engineering and i'm happy to see some appreciation all around the map. thank you

What a great video! A simple manner to explain all connections. Thank you!!

Great work! A few things I might still want to add: information theory as a foundation for electrical engineering, semiconductors (deserve a mention of their own, I believe), battery technology (bit hard to categorize, but very important for our modern tech world) and solar tech (other renewables are mentioned, could have put that next to power systems).

Glad you found a place for systems engineering. I was an SE for a long time in aerospace. SE can be found whenever the government (read DoD or NASA) wants a defense contractor to build something.

For the disciplines involved in buildings you forgot about Acoustic Engineering. They work with the mech engineers and architects to design the Façade and floors to mitigate the transfer of vibration and sound. They are also involved in internal wall construction and glazing design for noise ingress and acoustic privacy.

My background is in Mechanical Engineering. Though with this, I have been a design engineer for military spy planes and commercial jet engines. I have designed and built water filtration and microhydroelectric power in Africa. I was offered a contract as a nuclear propulsion engineer on submarines. Now for several years I have operated in mechanical and systems engineering within the field of space lasercom, or laser communication, which is an intersection between telecommunications and photonics/optics - which the industry calls Free Space Optical Communication (FSO). Each lasercom terminal (on a vehicle, a ground station, or a satellite in space) relies upon teams of software engineers, electronics, mechanics, optics, controls and simulation engineers to develop it, plus it relies on specialists in materials, processes, manufacturing, quality, and systems engineering. The domain of engineering which one is exposed to is fantastically broad, even for a single engineer!

Thanks for the video, this shows the big picture of engineering world. Myself humble to add HVAC and Fire engineering to Mechanical field, which myself is employed now. We design HVAC, Fire protection and Fire safety for buildings. I would love to explore another field in near future. To those who studying Mech Eng, keep going dont give up! its a very broad engineering degree which can unlock a lot of opportunities in different fields for you fellow in the future! Peace

What i love about being a mechanical engineering student is that my field is by far the most broad discipline ever. I can choose to work in almost all these other engineering fields as a mechanical engineer (to a certain degree)

A lot of insight i've earned by watching this video. This means a lot for me, and now, I'm proud for being a mechanical engineer. Thanks!!!

As an optical engineer, you kept me waiting up to the very end :)

As a mechanical engineer, i can certainly say that after completing college, I'm no longer a mechanical engineer but rather I'm now an "Engineer"

Thank you for putting so much effort into this 😮❤❤much love and appreciation.

Awesome! Computer engineering is the best...although I may be a bit biased.

Great video, just want to add a few extra bits. It's very hard to really group all the different applications of engineering into tight little boxes, because of how much shared knowledge each discipline has, how vast each discipline is and how multidisciplinary real world applications are. I've heard that the 4 main branches of Engineering is Civil, Mechanical, Electric and Chemical, with all other engineering disciplines being somehow a branch of one or more of those, but that's really up to debate. Also, there's often way more engineering disciplines in college to choose from. Things like Food Engineering, Transportation Engineering, Electronics Engineering, Automation Engineering, Environment Engineering, Nuclear Engineering, among many other areas that would usually be considered a sub-branch of another engineering often have full-fledged degrees or majors in many universities. And even then, the applications of each discipline are so vast that you can never learn everything there is to learn. Hopefully, if you go to a good university, you'll get to choose between a bunch of electives that will steer you in the direction you want to go. For instance, if you like the idea of designing structures so that they withstand loads and stresses without collapsing, you can do a major in Structural Engineering, but that's not available in every university, so you may choose to do either Civil or Mechanical Engineering depending on which type of structure you prefer to deal with and take the electives that correspond to Structural Engineering. Also, it's not uncommon to take classes in other fields. If you're into designing power plants, for instance, you might take a major in Electrical Engineering, but take some extra classes in Mechanical Engineering and Civil Engineering, since both of those disciplines are relevant to the design of power plants as well. Finally, you can even have interdisciplinary projects with non-engineering fields, like Computer Science, Design, Architecture, Surveying Technicians, Geologists, among others. What I like to say as a tip to anyone thinking about Engineering is to try to visualize where or with what you want to work after you graduate. Then, look at all the engineering fields that have something to do with that. Don't look only at their names, but also at their descriptions, curriculum and specially the electives they offer. Also, ask some former students if you can. Then, choose the major that fits best with your goals and interests.

Thanks for tackling this complex topic

Woooooo! It's up! Thanks for mentioning how everything is really interdisciplinary.

It's funny how you can start in one field and end up somewhere completely else on this map. I feel like I've gone all over the place. Started with a bachelor in mechanical engineering, took a masters in fluid mechanics (here part of marine engineering). Took a job as an aerodynamicist (here part of aerospace engineering). Now at that job, I'm the only one who happened to take a python course in uni so I'm mostly doing software engineering (part of computer engineering).

As you continue to make more and more maps, these maps could possibly be intros to playlists that dive deeper into each subject. Now that i have this map overview, I want to see examples, neat things, notable steps in subject progress.

I'm so happy you put audio, broadcast, and audio equipment engineering

Thank you for your time and effort for creating this video. It gives a wide perspective of things.

Great content, maybe for a next map content you can make the map of statistics. Statistics is a fascinating field and it has its application in every industry.

I like how the closer you are end to the video, the more physics it can get. Photonics is basically physics at this point.

I feel at home here mapping everything 😁🤣 Love your content very clear and organized I just got overwhelmed by the complexity behind building a skyscraper 🤯

Yet another great map from DOS! Wish I had this map when I was a young lad, trying to decide what to go into and what to study in college! Two things I didn’t see and expected, both in electrical engineering (my field), were power engineering and video engineering. And maybe some kind of reference to the semiconductor manufacturing industry would’ve been nice. But it’s a great video and I’m gonna share it.

I think it'd be interesting to put date stamps on each of these and make a heat map of when each area of engineering really came into its own. It struck me that most of these fields are less than a hundred years old. A decent number are less than 50 years old.

As an engineering student, my impression of aerospace engineering has so far largely been government contracted defense systems, aside from passenger airplanes... and I had a chuckle when you said "now onto the more positive uses of mechanical engineering!" as you were seemingly moving away from the subject of weapons, and onto aerospace engineering, because my reaction was "what, MISSILES NOW?" XD Thanks for this incredibly detailed visual representation of 'the products of ingenuity'

I'm a geodetic engineering student, but I didn't see my field explained on that map. the thing that has an intersection with my field is surveying. but as far as I know, geodetic engineering is more than just surveying and mapping the features of the earth. it integrates with some other engineering fields like civil engineering (of course), environmental engineering, geography, information system, and even aerospace engineering. well there are so many engineering fields that can be explored along with the development of times. i like the presentation and greatly appreciate your map and explanations. keep up the good works!

Thank you so much for this video, its really helped me decifer what type of engineering I would like to study at University.❤Thanks man

Excellent map!A map of electronics and communications engineering would be great!

As a mechanical engineer i confirm that, he covered pretty much everything, hats off to you

As a computer engineer I love the way you described both electrical software and computer engineering.

That is why we have a huge debt of gratitude to the great Seniors of Engineering people in the world community. Thanks for the extent and importance of the overview.

Chemical engineers largely do Semiconductor process engineering. Manufacturing Engineering and Industrial Engineering are also missing and these are huge. A lesser known one is Packaging engineering which might go in mechanical or in between mechanical and industrial/Manufacturing if you choose to include them. Didn't know about Marine Engineering, which peaked my interest.

Hello! I'm in the midst of getting my Masters in Chemical Engineering, and there are a couple of things I'd like to add- Chemical Engineering also relies a fair amount on Process Controls (as running a process to obtain the best results for the least cost is vital) Also- There's another intersection- BioMEMS, the cross between biology and MEMS. (I'm currently taking a Mechanics of BioMEMS class as an elective- complex, but interesting!) Awesome video, and I hope you have a wonderful day!

The suspension bridge from my hometown Bristol is a nice touch I must say!

Very interesting video. I have never seen a video like this before. It explains the major roles of every engineering field in a simple manner. 👍🏻

So grateful to find your channel! Such an extraordinary work! It's the materials behind everything, the truest thing to be said. That makes me study material science more even from an agricultural background. Also one of the fact that brings me closer to God, when I think that from where all of these would be built if Allah didn't put these materials out there for us to explore! Thanks for the amazing work!

Currently a senior studying ECE (Electrical/Computer Engineering). There seems to be quite a bit of bredth of topics even just in undergrad. There is the chemistry required for understanding how conductivity changes for different materials. Currently taking a class on Semiconductor Design, which talked about Fermi Energy, optimal unit cells for different materials/temperatures, and how band gaps change in respect to the dimensions of the unit cell. There is the programming side and analysis of algorithms/data structures, and within that, going lower level, theres the assembly languages and computer architecture. And going lower level there is the actual logic gates implementations. And understanding how they can be used for different combinational circuits or sequential circuits or memory. And even further lower the implementation of transistors when making the logic gates themselves. Which also includes the circuit analysis requirements. And then introduces spectral analysis (laplace/fourier) for understanding how the circuit responds to different input signals. And then that could be generalized into signals and systems. Which you could use signal processing techniques to analyze whether or not the system is stable, unstable, causal, anti-causal, or memoryless. Then the control systems aspect of determining how to make unstable causal open loop systems into stable causal closed loop systems with minimal error and low settling time. Then there are real world practical/buissness classes. Talking about optimal practices in the work place, such as how to estimate costs of making developing software. When to spend the effort on developing documentation, and how to do so. And all of these topics could be used in design classes. For instance I took a class on biosensor design, which talked about the process of how we can use electrical properties of systems to measure specific quantities. Such as measuring impedance of some blood sample, since cells have some capacitance specific for their size/shape. If you can capture cells by having receptors that bind to specific proteins/antibodys on specific cells you can then note the change in cell count to note the concentration of those antibodys/cells within the sample, which may be unique to a certain diseased state (I think reduced cd4 proteins can indicate HIV, might have mixed that up though). But you also have to take into account the fact that we have high frequency noise due to nearby powerlines, and baseline drift from low frequency noise, so you have to design a filter first which gets back in the circuits and spectral analysis. Then there is the legal parts of submitting for FDA approval and patenting and filing for trade marks... I barely remember the names of those forms though. This is not even mentioning the indepth topics within these areas. Like machine learning, or AI, or communication system (which I havent taken classes on, but other seniors have). And majority of the time you are just taking the prerequisites for these topics (2 years of physics, 2.5 years of calculus, 1 year of inorganic chemistry, linear algebra, discrete math)

I don't know how do you do it! Just such a huge task but you've somehow found a way to represent such huge information in an easy to understand manner! Thank you it always proves helpful! ❤

Wow blown my mind the way all are connected and no words the way you explained and keep connected..brilliant🙌🙌🙌🙌🤗🤗 The background and colour you use is just piece of marvelous art which itself guides as how much connected on field is with another.

Now you brought me into a huge crisis... I thought I was well set on Civil Engineering, but now Mechanical Engineering, Computer Engineering, Bio Engineering and Aerospace Engineering are growing in me...

I find it really difficult to settle on a certain discipline. I just started studying civil engineering at university but I constantly find myself being interested in other fields aswell, especially power and energy systems and renewable energy.

This video make me recognize engineering is a big words including many domains. Thanks.

Fascinating to see someone explaining with passion and has excellent delivering skills

I would have put semiconductors in there somewhere. You sort of touched on it in places but designing processors containing billions of transistors is really a field of its own.

Mechanical engineer specialized in waste management here. Many years ago, I worked on training engineers of any field, on waste management, so for a couple of months i had to interact with engineers of almost every field. Chemical engineers were by far the ones with the most insane depth of knowledge on an extremely wide variety of fields followed by mechanical engineers. The rest were more or less masters of their own fields, but Chem and mech ones were a class above as far as my experience through the years. I do enjoy cooperating with engineers of different fields. It's interesting to see the different problem-solving approaches each field applies.
