# EE switching into Pure Math

1. Apr 19, 2012

### Doppz

I'm finishing up my second year in EE, but realizing that it may not be the right field for me. When I applied to colleges, I didn't really put much thought into what I wanted to study; my parents suggested engineering and I stuck with it. I've always been very strongly mathematically inclined, which is why they suggested engineering. For the first year, I was too overwhelmed with being in a new location to really make any changes to my curriculum; I took the standard freshman engineering curriculum. This year, however, I began to question whether EE really is what is best for me.

I've finished the math requirements for my degree, but I'm left with an even stronger desire to learn more about mathematics. On the contrary, my EE courses have not necessarily struck me as that interesting. Useful to the world, definitely, but ultimately not as interesting to me as mathematics. Ultimately, I think if I were to continue EE and land a job in the field, I would feel unsatisfied with my position.

This term, I took a course in proofs (basically, an intro to real mathematics), which has been very interesting. It made me realize what a disservice to myself it was to take the "engineering" calculus courses. I want to rectify that; I want to learn math the right way. I would much rather see myself in 5 years in grad school for mathematics, on a PhD track, than having an EE job that I may hate. Obviously, I wouldn't earn as comfortable of a living with Math, but I think it would be worth it over having a job that I don't like.

So, I've spoken with math advisors at my college, and they will let me into the honors mathematics track. Next year, I'd be taking Honors Analysis and Honors Combinatorics. The Analysis course is the one that some highly motivated incoming freshman take that covers their calculus and analysis requirements, but is also taken by juniors and seniors who opted to take standard calculus their freshman year.

My only concern is that I would feel "too old", however, I know this concern is ridiculous. I'm only 19, and will be 20 at the start of next year. I'm by no means "too old", but I for some reason cannot get this feeling out of my head. I get this notion that it's too late to switch; but it's not, is it?

Any form of guidance is appreciated. I just want someone to talk to; whenever I tell my friends they just tell me "do whatever you want" and obviously the Math and EE advisors push me into their respective fields. I just don't want to graduate in EE and get a job only to look back 5 years later, bored, and wonder why I didn't challenge myself with math.

I go to Georgia Tech and pretty much everyone starts off at Tech as some sort of engineering major. So, lots of the math majors have a similar story as yours. They thought that what they really like was engineering, so that's what they went after, then after taking calculus, they realise that they are really passionate about math.

You are certainly not too old to switch. I started college when I was 21, I am not 26 and will be graduating in May. I am going to grad school and I won't get a Ph.D. before I'm 30. So, you are far ahead of me. And, as I said above, it seems most of the math majors at my college switched just like you did.

I disagree about the money thing, however.

Let's say you do the EE thing, according to the bls, the median salary for an EE is $89,000 (http://www.bls.gov/oes/current/oes172071.htm). This is cleary a good salary. Now, let's say you major in math, don't go to grad school, and become, say, an actuary (which is a popular choice, though it isn't easy.) Then the median is$87,650 (http://www.bls.gov/ooh/Math/Actuaries.htm) Now, this is a little lower than the EE, BUT, the actuary profession is growing faster than the EE, so it *might* be the case that in a few years these numbers will be switched. One other thing to consider is that actuaries usually are in the top of "job satisfaction" survys. Another important consideration is that there are many jobs one can get as a Math Major, not just actuary.

Now, let's say you get a Ph.D., then the median salary is $99000 (http://www.bls.gov/ooh/Math/Mathematicians.htm). So, in this case, you do better than if you get an EE. And, if you can work as a professor, you will have an almos stress free job (at least, this is what I am told.) 3. Apr 19, 2012 ### Doppz That is comforting, I figured I was greatly overreacting to being "too late". That is true, as well. It's just that you normally hear that graduating in engineering is an almost guaranteed job, while in math it can be tough to find a job. Though, I always challenged the validity of these claims anyway. Thanks for the response. 4. Apr 19, 2012 ### Robert1986 Yes, that is a sterotype with respect to the math major. But, to comfort you more, I read an article in Forbes that listed the three highest paying majors. They were: Engineering, Pharmacology and Math/CS. 5. Apr 19, 2012 ### SbF5 Why not double major in EE and Math or minor in Math? You cover all of your bases that way. You could also try getting an EE internship or doing some EE research with an enginerring prof to see if you really like it or not. Working in the field is a lot different than studying the field in college. It also helps to know you'll get a job when you graduate. The medians might be comparable but if you don't know the sample size or the job market they don't mean much. 6. Apr 19, 2012 ### Doppz The non-honors math courses at my school are a joke. Even the upper div courses like analysis and abstract algebra, etc. Which would be counter intuitive to the reasoning in me switching to math in the first place: I want to learn more. It seems like anyone can get an engineering degree, it's just a matter of working hard to do it. However, mathematics requires more intuition and creativity, which I've always felt that I've had, but never had the chance to really show in full. Also, probably math only draws those students that are very interested in the subject; while some are drawn to engineering mainly for the prospect of having a good career. Switching into math means not looking back, which is fine with me. I don't have any real desire for engineering and only chose it because it was suggested by my parents. It's not like I had strong desires to get into engineering, but changed my mind once I was there. What I should have done is sat down and thought about what I wanted to do the summer before getting into college. But, I was so overwhelmed with the whole thing and have always been rather shy...it just didn't happen. Thanks for the suggestion, though. 7. Apr 19, 2012 ### micromass Staff Emeritus Going into math is great. But you got to know what you're starting. You will likely make less money than an engineer and you will have a bit more trouble finding a decent job (not that mathematicians are jobless and sleep in cardboard boxes, but engineers have it easier). Also, you need very decent grades to go into math grad school. Be sure to take all of this in account before making a final decision. That said, if you find engineering boring, then it might not be something for you. But it is also very likely that you never had a decent math course before. Once you took analysis and algebra, then you know what math is like. Maybe you can take an analysis/abstract algebra over the summer and try to read it?? Also, let me remind you that pure math is not very applications oriented. So be prepared to talk about things that have nothing to do with the real world on first glance (I'd be inclined to say that all undergrad math is useful to the real world in some way, but this is often not very clear in math courses). If you want applications, then you should look in to applied math or physics. On the other hand, if you're interested in why math things are what they are, then pure math is the thing to do. 8. Apr 19, 2012 ### micromass Staff Emeritus Very true. Problem solving in math requires lots of creativity. But that's only half of what math is about!! Basically, I feel that there are two branches in mathematics: - Problem Solving - Creating theory Both require an extraordinary amount of creativity. Usually people prefer one over the other. People that say or think that math is just about mindless calculations are extremely ignorant. Math is all about concepts and ideas. It's about seeing an idea applied many times and generalizing it to a broader concept. These abstraction steps are often quite hard for most people and take a while to get used to. For example: Step 1: In ancient times, people have always worked with basic things like lines and circles. For example, to divide acres of farmers, one needs to know about surface areas of things. Step 2: The situation is abstracted by Euclid who introduces axioms for basic geometry and proves things from these basic axioms. Step 3: The situation is abstracted by Descartes and Fermat who introduces algebraic manipulation as a means to work with geometry. For example, points/vectors are being identified with couples (x,y) and we can say that two vector (x,y) and (x',y') are perpendicular if xx'+yy'=0. This is abstracted by the dot product $\mathbf{x}\cdot \mathbf{y}=0$. Step 4: The situation is abstracted by Hilbert and others who don't talk about lines and circles anymore, but merely about an abstract set H equipped with a dot product (called an inner product) $<\mathbf{x},\mathbf{y}>$ satisfying certain properties. In this form, this can be applied to a variety of very distinct topics. For example, one can say that two functions are perpendicular if $$\int_a^b{ f(t)g(t)dt}=0$$ As an example: the sine and cosine function are perpendicular!! One can even prove Pythagoras' theorem for functions instead of just basic geometry! This point-of-view may seem hopelessly abstract but is very important in applications. Applications give for example rise to Fourier series, Fourier transforms, quantum mechanics, signal processing, etc. To the OP: if you think this post was exciting, then you will like pure math 9. Apr 19, 2012 ### Doppz This is my plan; I have already started. I've bought a few books on Analysis and algebra and have been working through the analysis one on my own time. Most nights, I spend an hour or so reading from the Analysis book I bought (Understanding Analysis by Abbott) and have been really enjoying it. I think I have atleast some rough idea of what real mathematics consists of and it has substantially whetted my appetite to learn more about math. 10. Apr 19, 2012 ### sweetpotato OP: I majored in EE and let me tell you, certain sub-fields of EE can be quite math-heavy (such as signal processing) and if one was to get their PhD in signal processing, one may even have to take graduate-level math classes (I know this from a friend who did it). So some EE's who are especially mathematically inclined find certain subfields of EE satisy their "craving" for advanced math. However, I have read academic papers and done research (REU) in signal processing and while there is a lot of math, there are not many proofs (formal proofs being less important in engineering than in pure math). So if you find what you really love about math is proofs, such as you encountered in the "real" math class you took, you would probably enjoy a career in math more than a career in EE. 11. Apr 19, 2012 ### homeomorphic Depends on where you are. It's usually very stressful, from what I've heard. 12. Apr 19, 2012 ### SbF5 My question to you then would be this. Do you love Math enough that you'd major in it even if it meant living in a shack for the rest of your life or working at McDonalds if you couldn't find a job? It's great to be idealistic but nobody is going to care what your major was 10 years from now. However, you will if it means you can't provide for yourself or your family. The trick is finding the balance. IMO, once you reach a certain level of intelligence getting almost any degree is simply a matter of working hard and managing your time. Also, all science majors require a certain amount of intuition and creativity from those that pursue them who want to be successful. And really, if you don't have those things, you'll be mediocre at best no matter what your field. 13. Apr 19, 2012 ### micromass Staff Emeritus That's not the actualy choice that he's presented. Mathematicians get very good jobs. 14. Apr 20, 2012 ### Robert1986 I invite you to read my first post in this thread (it is right after the OP.) In it, I listed the median salary of an actuary (which is a job many a math major has taken). It is around$87k/yr. I also listed the median salary for mathematicians at \$90k/yr. These date were taken from the bls. Additionally, I mentioned an article I read in Forbes that said something (along the lines of) the three best money-producing majors are 1)Pharmacology 2)Engineering 3)Math/CS.

So, this notion that if you major in math you will be poor is one of the most incredibly ignorant ideas out there. Math, in it purest form, is an art, which is why the OP is drawn to it. At the same time, the result of this art can be incredibly useful to some people. Thus, if he majors in math, he will get to do this art for 4 years but he can actually take a (probably small) portion of this art and get paid rather well for knowing it.

EDIT:
Also, I currently don't have a degree; I'm still an undergrad. About 90% of the people I work with never went to college. Yet, somehow, we have all managed to avoid living in a cardboard shack or working at McDonald's. In fact, many live rather comfortable lives and manage to provide for their families. So, again, this notion that the choice is between engineering with a good job and majoring in math but, ultimatley having to live in a cardboard box is insanely absurd. It drives me completley insane. The math education people have received is already screwed up enough that it is a wonder that anyone wants to major in math in the first place, but spreading this falsehood that math majors are poor pretty much puts the last nail in the coffin for most (with respect to majoring in math.)

I'm not saying they don't. It's meant to be a gut check. To me, the OP sounds like someone who is caught up in the idealism of academia and is forgetting that life continues after your degree is finished. Getting a job in "science" generally seems to involve compromise. You find something to do that incorporates as much of what you like as possible and accept the reality that almost nobody is going to pay you to stay home and work on theory all day. If science isn't applied in some sense nobody can profit from it.

Exactly. That's the art. Well, I wouldn't say they're there to solve problems.

Also what he was saying about science, in its purest form. Effectively, science is the art of taking observations about the world and formulating theories from that. If any observation goes against this theory, it's tossed out or modified. Any theory that does not yield any testable predictions is not disprovable, and, therefore, nonscientific. There we go. Science stripped down to its barest form.

Lol.. nice. This is the last I'll say about this because it's getting off topic and it's so subjective anyway but I've met many, many more mathematicians that view their field as an art than physicists. I guess writing this reply is the art of abstracting my thoughts into written communication, lol. =)

To Doppz, the EE's I've met are very good at physics and even pure math. The signal processing and logic kids fit the glove for doing higher level math later on. I know some EE's that went to grad school for physics or math. They usually took a couple upper level courses so they had more of an option to spread out into other fields in grad school.
