How do I create and electric shock with a battery, I saw it before where i think a 8v batter had 2 wires connected to it and there was metal clamps on the end snd a remote thingy that controlled how much shock was created ans how many watts were used. Where can i learn to make that for my science fair?

This might relate to a question, are more than one photon packets in each wave cycle, but that is not my interest and I probably could not understand the answer.

This is connected to solving the problem of roadside bombs in Iraq. If a microwave signal could be pulsed at a IR frequency at a metal container having plastic explosives as its contents would an ultrasound signal (a mechanical wave) at the IR frequency vibrate the container? If so, if the ultrasound vibrations were at the same frequency of the peak IR absorption band of the N-N02 molecule would enough energy be generated in enough molecules to start a chain reaction to blow up the device well away from our troops.

Lacking much knowledge on these subjects my imagination is not hampered by the facts.

They would have a huge market. Think how great it would be to be able to replace a 20-30 year old V8 with a new hybrid.

I am trying to make a device that is computer controlled. It is essentially a robot. I would like to be able to control it from my computer through the USB port. Does anyone know of some site online that would help me learn how to make something like this?

I read about the jet beetle at http://www.ronpatrickstuff.com/ . Hopefully one of you with more expertise in this area can help validate or debunk this.

I recently learned about Nuclear engineering and how it works. It seems very complicated and certainly the engineers there must be quite intelligent. But on TV and other sources, nuclear power plant workers are perceived as not very smart! Why is this? Clearly, to be an engineer, you must be smart. So why would working at a Nuclear power plant be almost like something that bad engineers or engineers low in ranking do? Is that true?

I read some articles and they use the term "electron volt" and I read other articles that simply use the term "volt" Is there a difference and if so, what is it?

Thank You

Hi, just wondered if anyone's using Rosemounts and could help us out a little here. We are running a huge, fairly new facility here and have started running into problems with this type of transmitter. I'm talking about the type where you have 2 pressure sensitive pads, arranged vertically one above the other. The liquid level is calculated by sensing the presure differential between the 2 pads. What we THINK we are seeing is that these transmitters are very sensitive to pressure fluctuations and whenever we have a compression trip ,( we have centrifugal compressors) the resulting pressure transients are causing spurious high and low level trips on the production trains. Any help would be appreciated.
