    Physics simulation software

    hello!PinSky,I dont know if you have fond what you need. I got some you may like:crocodile physics. It can simulate physical experiments just as you drag something into its working place. I hope u can like it. to donwload it,Try google.( i have forget where i fond it OR u can send an...

    What is velocity ,momentum.

    THANK U Fra . now I have got some idea of what you said.It is really very wonderful.

    What is velocity ,momentum.

    THanks Demystifier I have checked the websites you gave,and I found that (maybe) it is still an unknow question,people are working on it.Right?

    Do we have different photon

    Sorry,my English is bad,I could not express my idea clearly.But I really THank you Sojourner01. maybe it is like this.When an electron-positron collision is occuring,we may get something as you said,but it is just possibility. but I still have something unsure.I will try to work out...

    Do we have different photon

    :confused: when an electron meets a positron, both the electron and the positron cease to exist, and pure light comes flying out,and then the photon(light) will decay into a \mu^- \mu^+ . MY question is what is the difference between the photon that comes from the annihilation and a normal...

    What is velocity ,momentum.

    :confused: (my English is bad,so please try to understand. :) As we know that bohr said we could not know anything without detecting.To talk about anything of a particle without measuring is meaningless,and we don't know what exactly happend during the process. Someone think maybe it is...

    How would you define Frequency in terms of quantum model?

    HI kokok. I think mybe you could not image that,because you can't,and nobody can either.It just have a Frequency.What is it? it related to something else.Just think about spin.Maybe they are the same at this point.
