High Level math in the real world

Do you really use anything outside of calc 1 in the real world? I mean i'd imagine that even careers that require you to use some specific areas of advanced math are probably little more than punching in some data into a computer for which the "math" has already been implemented through some program.

I like math and not trying to offend anyone, but when my professors say that yes math is used in the real world i feel that they don't know anything of the world outside of academia. Then again, i don't know much of the world outside of school either but this is just how i feel.

Can someone give me some specific careers that require extensive knowledge of math and what area/sub-areas of math are used in this field?

thanks!

Re: High Level math in the real world

I didn't see an edit button anywhere so sorry for double post...

I am a math/CS major and i feel that the only thing that i can take away from my math degree and into a world outside of academia is the ability to pay attention to detail, turn giant problems into smaller problems, and a way of thinking that allows me to solve problems in different ways. I know these are good skills to have, but i guess i'm just wondering if the actual math i learn will ever be useful?

I went to the maa conference in boston this past summer and i went to a talk where a phD in math told everyone in the room that what he uses nothing of what he learned in school and that when he was hired for a job a person with only a bachelors degree had to teach him new skills to do his job. I think i'm worried about something like this happening to me (although i plan on earning a masters in statistics now).

anywho thanks again.

Someone with an understanding of the math involved must program the computer.

Writing programs that simulate the real world involves at least a good understanding of linear algebra, classical physics, which often involves partial differential equations and the numeric methods that go along with approximating solutions, etc.

By the way, once you've made 20 or more posts, the edit function will be available. This is an unfortunate but necessary anti-spam measure we've had to adopt. We apologize for the temporary inconvenience.

I understand that someone had to understand the math in order to create the program, but people who USE the program don't really need such an understanding. It seems to me that careers requiring advanced math are pretty much limited to academia.

Also, its no big deal about the editing posts function, thanks for the heads up though!

I'm the "someone" who writes those programs, and thus need to understand the math.

You were who I had in mind when I made that statement!

Re: High Level math in the real world

Well that's pretty cool that you're the programmer that needs to know the math in order to write the program. That gives me some hope that i can hopefully use some higher level math wherever i end up.

Also, this is off topic but i didn't want to start another topic for this..Do you guys know of any online calculus (1-3) tutorials i can find online? I took these classes when i was a sophmore and to be honest i don't remember certain topics such as: polar/cylindrical coordinates, infinite series(ugh..), trig substitution, etc. But if i were to see them again i'm sure i'd be able to pick them up pretty quickly.

Re: High Level math in the real world

Open Course Ware from MIT

Single variable calculus is cal1 and cal2, multivariable calculus is cal 3

download the lectures for theory but also download the recitations for detailed solutions to specific problems. DON'T FORGET THE RECITATIONS!!

http://ocw.mit.edu/courses/mathematics/

all free btw.


also grcc instructor is awesome with tons of worked out examples, here is youtube sample but all lectures are also available FREE ON ITUNES

heres calc from princeton

Re: High Level math in the real world

if are good with you maths you could easily get into an investment bank building model.

or if you are interested in sports you can consider - Sports Product Modeller building models for companies or individuals.
