The "Conation" originaly I meaned "desire", my Eng-Chi dict is not standard, I use a computer instant dict to translate Chinese to English and directly copy it on websites, and I am poor in language, so maybe it is this problem.

That is illegal, you should know...

Thanks for your congratulations. And I am not in short of money... And I am contented in the comsume of life, but I want to buy a big thing, now I am still saving the money for buying it.

I have begun my business at now 16 old... ----------------------------------------------------------------- I am 16 now, I have a Chinese general website, where has the info of Religions, supernatures, PDA, smartphones, CPUs, Computers, social views and my personal diary and views. Recently I...

Logical view, every matter has mass, otherwise they are non-existence! Maybe in our now technologies are still unable to detect the photons' mass, but without doubts, photons were from the big bang (all mass were concentrated at it), since that, photons should be having mass.

Quote: "if light had mass, the rotating balance would suffer an additional tiny torque" They set this hypothesis, but I don't know whether they had detected this, the abstract had not told. I think the limit of the experimental accuracy is not the main matter. So I am hard to judge your view...

But this link pointed out the photons have mass... http://www.aip.org/pnu/2003/split/625-2.html ------------------------------------------------- The content is: Number 625 #2, February 19, 2003 by Phil Schewe, James Riordon, and Ben Stein A New Limit on Photon Mass A new limit on...

Or any other possible corrections?

More clear explanation, From m=m0/√(1-v2/c2), If we don't let the photon's mass be zero, we must have a higher speed than the speed of light to replace the c2. . .. therefore is, m=m0/√(1-c2/x2) *x is an unknown value.

But I think maybe the extreme speed of cosmos is not the speed of light, is a bit faster, thus the photon's mass just not be zero. Or the equation always has error, the actual result is a bit higher than or different to the calculation, but how can modify this equation with slight factor?

Photon's mass is zero? ----------------------------------- According to the SR's equation : m=m0/√(1-v2/c2), if the photon's velocity is the speed of light, then the photon's mass should be zero in value, but recently scientists have measured the photon having mass, but I forget the very...

Also an example from Special relativity is, the equation F=ma is not correct when the velocity is near the speed of light.

Thank you very much!

How is the principle of the operation of radio telescope? I am interesting that how can radio telescope translate signals to image. Does any experts can tell me?

What is string theory? And how come is the string theory? Sorry, the quantum theory is not my strengh. Is there anyone can telling me? But I heard some peoples saying that string theory world is not as same as actual life.
