The discussion revolves around the derivation of the entropy formula for an Einstein solid in thermodynamics. Participants are examining the transformation of the equation involving the logarithm and the constants related to energy and particle number.
The discussion is ongoing, with participants expressing confusion about the derivation and correctness of the formula. Some guidance on using logarithmic rules has been suggested, but there is no consensus on the validity of the original expression.
Participants reference a textbook for the formula, indicating potential discrepancies between the text and their understanding. There is uncertainty about whether the expression represents an approximation or an exact formulation.
iScience said:S=kln(\frac{eq}{N})N --->= S=Nkln(\frac{q}{N}+1)
i understand that the e goes away and the N exponent comes down but where does the +1 come from?
iScience said:there are no more parentheses that's what's in my book. is this even an approximation??
