Well, I thought I read that a typical M-16 round can travel at about 920 m/s; that was what I originally had in mind. I mentioned 6 km/s because if you can move that a significant amount, you can easily deal with the other. At the very least, the idea would be decent science fiction fodder. :)

I was thinking that the separation between the pulses could be used to give a frequency. It's true that a single pulse could be used to detect doppler shift, but do you think that a projectile would be significantly blue shifted to easily detect? I wasn't sure, that's why I thought a pulsed...

Thanks for responding to me! Sorry, I wasn't clear. The frequency I was referring to was not the frequency of the electromagnetic radiation, I was assuming that frequency would be fixed; something in the radio band. If one is releasing multiple waveforms in succession and counting the rate...

A Big Problem: (a) sub-problem 1: Assuming that a radio transmitter emits a radial pulse 'K' times a second, what would that frequency need to be in order to detect the doppler shift of an object traveling a 6000 m/s? (b) sub-problem 2: If one had a cathode ray source which was outputting an...

Physicists tend to learn as much computer programming as the physicists care to. Many of them are self-taught on some level. Self-teaching a subject seems to have a randomizing effect on the precise skills one develops. If, for instance, the physicist found that they were really interested in...

Oh... I didn't realize that it would do that. Sorry. :redface:

It's probably not anything that you need to worry about. If it produced the library and the executable that you need, then it's fine. Taken from a website describing the 'gcc make' Error codes: [foo] Error NN’ ‘[foo] signal description’ These errors are not really make errors at all. They...

"Do loops". Pseudo code: ! This defines your vector/matrix size. parameter (N = 2) real MatrixA(N,N) real V(N), SolV(N) ! Rand stuff ! ! You fill in the blank ! Init Matrix do j = 1, N do i = 1, N MatrixA(i,j) = rand() end do end do ! Init Vector do i = 1,N...

I have taken several classes related to CFD. Although I come from a physics background the classes have been/are from the Mechanical Engineering department. Note: These are questions you ask yourself, don't answer them for me: 1) Can you solve the heat equation? a) Can you do...

Isn't this a bit dangerous, though? Most people go to a University to gain an education. At the moment, an undergraduate education is a truly expensive investment. Wouldn't treating academia like a business make it more damaging to a student's bottom line? Let's imagine that by some chance...

I'm interested in seeing the responses here too.

As I understand things, a "growth investor" is someone who invests in a brand new, untested company and hopes to get a high return on their investment. Pros: High Payoff "Principle Investment can double?/triple?/exponentiate? if the company succeeds." Cons: High Risk "All money invested in...

Also understand that lisab and JakeBrodskyPE likely have an order of magnitude or two greater experience than I do. Their thoughts and opinions regarding how the real world works are more realistic from my own. :)

Experience will make you a better Electrical Engineer, but having a Masters will give the company you work for one more excuse to not lay you off, I would imagine. This thread needs more input than mine...
