Stockpile :: Complex Variables  Problem Solving SessionsNode id: 3533collection
About Stockpiles:
 There is one stockpile for each area of Physics and of Mathematical Physics
 The stockpiles of resources for teaching and learning, and problem solving.
 Items available under Lessons, Problem Solving and Evaluation and Assessment are designed as stand alone, independent resources.
 Stockpile are useful for those who have some exposure to the subject. Recommended for students attending a course and for teachers.
 Choose a topic and start learning, or start solving problems.
 Each module will cover all aspects of teaching and learning for a set of a small number of closely related topics.
 The Newbies will find Self Paced Courses more useful.

Works of Masters always have something to offerNode id: 723pageI take the best from every one. But GOLD FROM OLD, There is always something to learn from MASTERS;
In this age of internet, there is a tendency to open internet and learn from Wikipedia and similar sites. While this has its own advantages for a mature learner, I recommend that a beginner must learn from the masters even though the learning curve may look very steep. This collection is an attempt to encourage younger generation to leart role of contibuting to the subject and from the very best. There are many who contributed to pedgogy and teaching. Many old texts become 'obsolete' simply because is it fashionable to go for the latest. It would be foolhardy to ignore these and other works, so we include here snippets and quotes etc. from many other sources too. It is hoped this will provide incentive to the younger generations to ask for more. "Choose the very best from every one"

[QUE/SM03001] SMPROBLEMNode id: 5065pageConsider a system of $N$ atoms. Assuming that they can exist in two states only. The ground state having energy zero and an excited state having energy $\epsilon$.
 Find the number of micro states with total energy $U$.
 Write an expression for entropy and using Stirling approximation for the factorial $$ \ln (N!) \approx N \ln N  N$$ find the temperature of the system and hence show that $$ U = \frac{N\epsilon}{1+ e^{\epsilon/kT}}$$
 What is fraction of atoms are in the excited state at very large temperature $(T >> kT)$?
