marty thanks for the really informative response to my last question (regarding mat215/orthogonal thinking/physics). Quick additional question. You said "Btw by engineering I’m thinking something like MAE not COS. Therefore, my naive guess is that you’ll get more of a different perspective delving farther into math than you would from physics." Given the additional info that I'm ORF, would you rec more math or more physics? (or I guess I could just pursue both to an extent)

Response from Marty:

Oh interesting. I think Scipio should weigh in here cause he’s orf plus done a bunch of math stuff. I think in this case you would learn a lot from both directions. Orf stuff tends to be pretty applied math, so it’ll feel pretty different to do more abstract math. Physics thinking is also decently different though so I think it’s worth taking a class or two there. Yeah you can’t really go wrong with these two options.

Response from Scipio:

If you’re moreso interested in “new ways of thinking” I think physics is probably a good idea, as I imagine those classes will be more different from 215 than other classes will be. Topo is also fairly cool and different from other sorts of math you’ll have done prior to it. If you haven’t done COS, I think those also do a good job exposing you to a different way of thinking ab the world.

(rising soph) ab cos major but thinking about transferring to math. Freshman year, I took 201/202 instead of 215/217, which I will probably take this year. Will I be at a disadvantage if I transfer now?

Response from Pichu:

sorry forgot to answer this question. 201/202 are pretty useless for majoring in math so you will be a little bit behind than most math majors yes and will have to play catch-up, however i know a couple math majors who successfully completed everything after taking 215/217 sophomore year.

you should take some classes that fulfill math departmentals during sophomore year that don’t require the knowledge of 215/217. during the fall i would suggest ORF 309 cuz it’s cross-listed as math and it’s easy. during the spring, a popular class is MAT 377 (graph theory). other potential classes are like COS 340 and MAT 378 (game theory) off the top of my head.

then junior year you can start taking the core classes (complex analysis, algebra, real analysis, and topo/geometry/something else) and junior seminars. the junior sems might be a little over your head but heck they were over my head too. you’ll need to take a total of 8 math classes total (4 core + 4 departmental/cross-listed) so if you can get 2 done by the end of sophomore year then you won’t be that far behind most math majors. just make sure you take 215/217 sophomore year and at least 2 math departmentals (make sure to check which courses count as departmentals, you’d be surprised by some easy courses that count as math departmentals even tho they’re not cross-listed, like cos340 and orf335).

@pichu I applied to princeton wanting to do math but I have confidence issues lol so I diverted to econ when I got here and am currently in 201 but I sorta wish I'd stuck with math, any suggestions for how to get back on track? should I take 204 or 217 next semester? will I have to take multi at a higher level next fall?

Response from Pichu:

sorry about the confidence issues, you can do it! math is hard but it’s not that bad, i think anyone can do math if they try!

i’ve never taken a multi course. the only math class that you learn multi in besides 201/203 & 216/218 is 350, but that’s not a very popular class. definitely don’t need a high-level multi courses to be a math major, just need to be able to learn relevant stuff on your own as it comes up in other classes. so 201 is fine to get a decent base understanding of multi.

next semester i’d recommend 217, definitely NOT 204 if you’re thinking of majoring in math. then next fall i’d recommend 215 because you need that to prepare you for higher-level analysis classes. you won’t be prepared to take like complex or real analysis next fall (MAT 335 and 320) without having completed MAT 215, so alongside 215 next fall you could take Algebra I (MAT 345) or some cognates like ORF 309 or COS 340 (would recommend one or both of these classes, orf309 > cos340). Those will count as one of your 8 departmentals for math.

Then you could take Fourier during soph/junior spring or Real Analysis during junior fall to fulfill your Real Analysis req; Complex Analysis and/or Algebra I and/or Topology junior fall for your complex and/or algebra and/or topo req. you could also take game theory or graph theory during soph/junior spring to fulfill the topo req. basically, MANY OPTIONS

but i’d give 217 a try first this spring. most people will have taken 215 and so may approach math problems differently than you do already so that might be kinda intimidating, but really try to stick it out and learn the material, you’ll really learn a lot.
