Ugh, Stata. I love what it can do, but I hate doing it. It's like using a DOS port of MATLAB.

I run Windows inside a virtual machine on my HackPro, which runs Mac OSX inside a virtual machine, which then uses X11 to run unix Matlab. As long as I don't sneeze, it runs perfectly.

When you run Matlab in command line, does it only output ASCII graphics and charts that look like they were made in Excel '97?

Looking like I'm only going to be able to take Programming in C++ and Linear Algebra. I just transferred to a 4 year school and everything else I need is full.

Anyone have any opinions on Linear Algebra? I didn't find Multivariable very difficult at all (this was the last Math course I completed). Can I expect the same from Linear Algebra? I can either take it with a teacher that has gotten mixed reviews Mon and Wed mornings or take it with a teacher thats gotten awesome reviews Mon,Wed,Thurs and Fri. Don't really feel like being in school 5 days a a week this semester, I'm kind of leaning towards the two day course since I basically teach myself half the time anyway.

Probability and Random Processes for Electrical Engineering by Alberto Leon-Garcia.

My professor for this class did his undergrad, masters and phd at princeton and apparantly has a bunch of stories about working with John Nash. That should be rad.

Just got an offer to work in a lab doing this...

"Currently my group is focused on applying a state-of-art technique, patch-clamp fluorometry, in studying the biophysics of ion channels. This project involves both patch-clamp recording, the foundation for modern neurophysiology research, and more importantly, optical recording of fluorescence signals. The student will get an opportunity to get familiar with amplifier, DC/AC conversion, computer automation of electrical and optical recordings, laser, CCD cameras, etc. A related publication is attached for your reference."

So fucking excited!

Behavioral Economics
Market Design
Topics in Microeconomic Theory
Intro to Linear Models
Intro to Topology
Intro to Algebra

This is completely unrealistic and I will probably end up pass/failing one of the math classes or one of the econ classes. I might also hold off on algebra until next year, when I can take it with a much higher rated professor, and take Economic Theory of Organizations instead.

Linear Algebra is vital in making MV calculus work, but the classes themselves have pretty much nothing to do with each other. Completely separate worlds as far as intro courses are concerned.

That said, linear is probably way more useful in general than multivariable. Most MV problems you can finagle in MATLAB or Mathematica. Linear algebra not quite as much, it's more principles and less calculation.

Take it MWThF. You have no idea how important a good math teacher can be, especially for something as core as linear algebra.

That sounds awesome as an EE type position too. I wonder if they use LabView for the automation. Either way, congratulations.

Got bad news from my supervisor yesterday. He thought I would be able to work the test engineer position part time, but HR told him this wasn't possible and that'd I'd have to be full time in order to take the position. So I can't move into it now, but he told me they would essentially reserve the spot for me if I wanted them too. So I told him yes and I should be finished by December, so I'll be able to get started right after the holidays.

Met with the professor about the aforementioned lab I thought I wanted to work in and realized it's not really what I want to do. VCU's department of neurobiology does more with brain splicing and neuronal activity, which sounds awesome and more up my alley than studying the ion channels. Still so torn between trying to get involved with that versus pure physics. There are some sweet labs working on spintronics and relativity that I want to look into. Wish I could make up my mind.

I thought both Linear Algebra and Vector Calc were easy, though Linear Algebra definitely took up way less time because the problems aren't as involved. They are both completely different though, but from the sounds of it you should probably be fine.

Do you know what book you are using? If you aren't using a book by Strang (MIT Professor) pick up a copy for reference. I used his fourth edition (I think) and it was an awesome book. It isn't a 'plug and chug' type of book and focuses on trying to get you to understand the concepts, proofs, and recognise properties of matrices at a first glance.

Which did you use? "Linear Algebra" or "Linear Algebra and it's Applications"?

Strang also has video lectures on OCW. He's a boss.

I used the "Linear Algebra" one. The only application in this book that I remember, and it was very very slight, was on circuits.

"Introduction to Linear Algebra" fourth edition

I did really well in Linear Algebra, generally the first half is just matrices and computations, the second half gets more and more abstract and involves more proofs (in my course we didn't have to really write FORMAL proofs but we did have to understand the proofs for various theorems to get by on the exams).

If you're good with math honestly a shit teacher doesn't matter (in my opinion at least). I've had great teachers and I've had awful teachers but as long as I did my homework I've never had less than an A in any math course. A lot of the kids in my linear algebra course complained about our professor but I did fine.

Also what bizarre linear algebra class did you take that the problems weren't as involved as vector calc? In my experience it was the complete opposite, vector calc was a breeze but linear algebra I'd spend a good 4-5 hours a week working through the problems, besides the textbook would have like 4-10 problems per "exercise".

Also worry about it, how many credit hours are your courses that you're taking 6!? PS those sound really interesting.

anyways, this quarter is:

Applied Econometrics
Applied Microeconomics
Economic, Social, and Ecological Systems

4 credit hours each. it's gonna be rough, but overloading is surprisingly common at my school because the scheduling is so flexible. and again, i'm probably going to switch out Algebra for Organizations, and i'm almost positive i'll either pass/fail or audit one of those classes.

Economic, Social, & Ecological Systems sounds ice cold, too. Are you using a textbook for that one?

Nah, it's 4 smaller books, "The Invisible Heart", "Manufacturing Green Prosperity", "Rethinking Macroeconomics For Sustainability" and "Understanding Modern Money" plus some random Veblen readings and a lot of Post-Keynesian/Institutionalist journal articles.

My Masters program focuses at least one course per quarter on heterodox ideas, which is pretty ice cold.

Taking a class on molecular motors with my adviser, and auditing a mechE class on statistical mechanics. Then reviewing linear algebra with my friends once a week. My quarter went from all super Ice Cold classes, to real work. Fugg.

At least its useful for my research.

got accepted into a research lab on campus with my favorite professor. I'm meeting with the professor's research group on thursday to figure out which project i'll be working on.

from his website:
"My main research interests cover a range of topics which could be described as a modern systems theory. In particular, I'm interested in modeling, analysis, and control of real-time, embedded, networked and distributed cyber-physical systems. Other research interests include geometrical nonlinear control and mathematical systems theory."

try using mathematica, or if you can define the equation that results in the graph you can use wolfram alpha which is free.
