Thank you for the response. It's just that seeming non-correlation between the two sentences what make me confused. By the way what you have said about momentum does not apply to angular momentum, angular momentum comport like energy when one talks about the decomposition of motion into...

In the course of theoretical physics by Landau et Lifshitz volume 05 §4 (the signifficance of energy ) we have: " The momentum and angular momentum of a closed system depend on its motion as a whole (uniform translation and uniform rotation). We can therefore say that the statistical state of a...

Well, very nice One should take a whole picture inside the box first

thanks No but i d'ont have any idea about astrophysics and i find a problem with the method of the estimation of NS's period during my reading P.S we are in summer holidays , i Like know some physical basics of neutron stars and hight energy astrophysics excuse me

Thanks

Thanks

A neutron star cannot spin with less than a certain critical period, or else it will start to lose mass from its equator due to the “centrifugal” force. Estimate this period.

yes , it will be clear thank you

can someone Explain the NS-NS or NS-BH or BH-BH mergers proposed to explain short GRB’s. Thanks

can some one give me a link or an article or his argument which Explain how the Bethe-Bloch formula is used to determine the energy of a gamma-ray photon stopped in a spark-chamber detector. thanks

Thank you

please i'll like to ask if someone have a code written in c++ or in foltran90 on 4th order runge-kutta method of numerical computation. thanks

I think that i understand your viewpoint in classiccal mechanics the kenitic energy is T=(1/2)mv² but if we take the expression of energy in relativity for free particule E=mc²/sqrt[1-(v²/c²)] and make a taylor development for v very smaller than c we find E=mc²+ (1/2)mv²+... =T u may...

it may be simple if we calculate energy in special relativity by the relation W= T2-T1= integral F.dr W Work T kenitic energy F force dr deplacement element this formula is generalisation of the case in classical mechanics the force is rate of change of momentum in time the component...

yes that's right
