    Propagating Uncertainty for sets of data?

    I'm writing the paper on this experiment I just did. Basically I took sets of data for two variables (x,y) and I fit the points to a line in Origin to extract the value that I was trying to measure (J). *Using generic variables here* I found a value for J where J = [8*∏*x*a(b+c)] / y I...

    Complex circuit exam practice questions?

    Well if you already know how to work with the circuits you have seen in class and in your textbook and want more, I would go to a library. If you are at college, the library should have some good books for that stuff. Besides books, I don't know.

    Coffee How much coffee do you drink?

    I also strongly dislike being dependent on coffee but my parents are dependent on it and that may have carried over to my genes. (If dependencies were genetic) Before I started drinking coffee, I could never stay awake during school or any other part of the day so I saw coffee as my only chance...

    Computer Engineering or Computer Science Major?

    You just have to find the beauty in math to make studying easier. Besides calculus (1-3), you should only need 2 or 3 more maths after that (linear algebra and diff. equations) depending on the school

    Programs A joint major in Computer Science and Engineering

    I am trying to figure a similar question out myself. I am interested in integrated circuits and will probably end up getting a masters in computer engineering. I guess it depends if you want to work with purely software, purely hardware, or both.

    Why Does the Sun Bob Up and Down in its Orbit?

    That's an interesting point about the orbits being on slightly different planes. My guess would be that the moons of those planets may pull them at an angle but I doubt that is a significant cause. On the black hole in the center stuff, if you look at a rotation curve for the milky way, you see...

    Resistance as a Function of Temperature

    No offense taken but does that imply that we just used the equipment wrong or that the equipment malfunctioned? I still have to compare results with others who did the experiment to see if this was common.

    Resistance as a Function of Temperature

    It seems that the resistors we used had a negative temp. coefficient which is weird. All I can do is blame how the parts were made?

    Resistance as a Function of Temperature

    Homework Statement Well this isn't a homework problem, but I am writing a lab report for a lab we did concerning the change in resistance as a function of temperature. Everything I have read says that the resistance in conductors should increase with temperature, but all of our data shows...

    I bought a Microcontroller Experiment Board

    Hey Bill, thanks for replying. I am starting to get excited about this... mostly for the programming part. I have no experience with soldering but I plan on researching it a bunch first. I ripped apart an old stereo system and have some broken circuit boards. Is this what you mean by a junk...

    I bought a Microcontroller Experiment Board

    Hey guys, I might be in over my head on this one but I was looking for an electronics project... I really just into this kind of stuff and plan on majoring in electronics engineering. I just purchased a Microcontroller Programmer & Experiment Board (by Velleman) at Radioshack because it looked...

    MATLAB 3D Distribution Plot on Matlab

    Hey guys, I am taking an intro to MATLAB course and it gave me the idea to make a program to time my rubiks cube solves. I'm not too experienced with the timer functions (tic toc, timer) so I don't know where to begin. What I am looking for in my program: -A cue to press a key that starts...

    How can an object have an acceleration of 9.81m/s^2 when there is

    It's all about the reference frames.

    Calculating tangential velocity of an air parcel circulating a tornado

    The tangential velocity is slower near the center of the disk because it doesn't have to circle around as big of a radius as the outside. Imagine running around a circular track... the people on the outside have to run faster to keep up with the people on the inside lanes. This is not true for...

    Physics 3rd class in physics any advice?

    Hit the books and stick it out to the end. Evaluate your future after the semester grades come in.
