Dear friends, As you know, in CGS units we have vacuum permeability as unity (1). so H=B and we use Oersted for H. on the other hand, in SI, permeability is (4 x pi x 0.0000001) and we use Ampere per meter for H. unfortunately after trying for couple hours, I couldn't derive the algebra of...

Thank you.good explanation.but one thing. Absorbed energy by a planet I think will lead reactions to less complex structures I think.

For example : H --> He + 2 positron + 2 neutrino + energy. I know that the energy increases the entropy of the surrounding and that overally the entropy increases but i wanted to know any more information or situations or reasons.

Thanks! that really helped

Yes,that is the second LAW of thermodynamics but I don't understand where's entropy is increasing,As anywhere you see there is materials being produced with less entropy,and in such reactions of course some heat will be produced too,If that heat is increasing the total entropy,so why the...

I've seen it all , Thanks anyway.

Thanks , So that is the matter of enthalpy of the reactions somehow?

Hi all, I've been around with this question for a while,I googled it and I found some information,But I want you to help me more, The question is : From the beginning of the universe,Anywhere of the Universe you see,there is reactions that due to them new materials are being produced,and...
