\dfrac{\mathcal{F}^{-1} \Big( \sqrt{\mathcal{F}(f(x))} \Big)}{f(x)} = g(x) g(x) is known, and for an example let's say g(x) is something simple like g(x) = x so we have \mathcal{F}^{-1} \Big( \sqrt{\mathcal{F}(f(x))} \Big) = x \cdot f(x) my question is, how do i find f(x)? it's...

Hello, I have to give a presentation on an application of electromagnetic field theory of my choosing, and I was wondering if anyone had any suggestions that might be more interesting than the ones that have been suggested. It's for a 2nd year university level physics (E&M) course, so the...

Hi, I have an issue I hope you guys will help me solve. I need to re-create a problem seen on Rail equipment where high voltage spikes are affecting equipment (resistive load) normally running on 600VDC. I thought about using a simple RC circuit to produce the spikes over the 600VDC...

Hey, My name is Mark, I am currently in grade 12. This term we have been given an open topic experimental investigation as an assignment. I have done some research of my own and found a couple of sites dedicated to giving you ideas for this kind of thing but I just really haven't found...

Do you have any electrical engineering senior design projects suitable for someone who is BME/EE? This is one of the (few) classes necessary if I want to also complete the EE major, which I sort of joined for fun, because (i) they have all the math courses, not sure why and (ii) the professors...

It's that time of year again...time to renew my license plate! I currently have a generic one. Boring! So I'm trying to think up a new one. Some ideas I've thought of or heard: LIMSUP, LIMINF, RLANLYS, PR MTH, AXMFCHC. So I like math. But anything geeky could work. Ideas anyone? (Limit to 7...

I'm looking for some sort of project to do this summer. I was looking around, and I heard about making a small, home-made cyclotron, but it sounds like materials would be hard to get and expensive. So, does anyone have any examples of a great, preferably time-consuming project that I could...

I want to write a code for a MCU, the MCU will output an image to a TFT screen, and here is the tricky part: I want to make the final display to mimic old CRT， which means it will shrink, skew, and out of sync randomly, and the image will be constantly shaking. I hope the FPS would be 60...

I need some ideas for a physics or astronomy related speech?

We were working on the van yesterday changing spark plugs. the air filter was in the way so I went to remove it and a small socket fell into the open spark plug hole into the cylinder. We went out and bought a small spring loaded magnet to fish it out, but it kept picking it up from the side and...

How to find copper sulphate resistance. I know that with the increase on concentration to the solution the resistance will decrease because of less water in it and water is a conductor of electricity but i want to know if there is a method of finding the resistance. I was thinking to place...
