Hello all, We know that (E,p) are the components of a four vector and it is called the four-momentum. Likewise (V,A) are the components of a four-vector and it is called the four-potential. But it seems that the four-vector with p-eA is the most important one, yet I don't recall every...

Hello admins, I posted my "Gunn" question in the wrong forum :blushing: . I posted it in the Engineering Systems forum but meant to post it in the Electrical Engineering forum. Is it possible for you to move it with your godlike admin powers? Or at least delete it so I can start fresh...

Hi Berkeman, Judging by your signature, you might be able to shed some light. The experiment is on [PLAIN]www.altair.org[/URL] and the guy seems to be a HAM enthusiast. I sent him an email asking for a starting point.

Gentlemen, The website [PLAIN]www.altair.org[/URL] describes how to create a homebuilt quantum tunneling experiment which I would like to try. It requires the use of a Gunnplexer. If I search for that term, all references to that term seem presuppose more knowledge that I have. Can...

Thanks, I'll try the EE forum

I'm sure you guys browse all of the forums. So maybe you can answer my question. I want to know what a Gunnplexer is. Which forum would be my best bet for getting a good answer?

Hello, I am trying to learn about Gravitational Time Dilation. I came across the following formula for time dilation in a uniform gravitational field: T_d = {1-} \frac{gh}{c^{2}}} but I cannot find any derivation for this. Can someone point me in the right direction? Thanks

Thanks, guys. I will read up on this gravitational time dilation and pursue this after that.

Are you referring to the phenomenon known as "gravitational time dilation"?

My friend and I are in a two story building. I am on the lower floor, he is on the upper. We are in a constant gravitational field. Is it true that our watches cannot be synchronized? If so, what is the proof of this claim?

That's very interesting. Where can I learn what you just stated?

I stand shoulder to shoulder with a group of people, we all face the same direction. We all have synchronized watches and nobody is moving. We face a second group of people, facing us. They all have synchronized watches and nobody is moving. Now suppose that my group feels like they are in a...

Yes but google is like taking a bath in a tub full of wiki. That's why I use this forum so that I can get some direct answers. But I will do as you suggest. I will read up on "quantization of gravity" and search for the unresolved issues.

Oh sh********it! That means the problem is client side! I'm doomed. I'm using ncsa mosaic. I mean lynx. ...Gopher...

Ok - so gravity is weak compared to EM. But all I ever hear about is how "gravity cannot be quantized". The independent forum is full of people trying to quantize gravity. My question is really simple - where precisely does the controversy arise so that I can learn the difference between...
