Cyclone ke side effects

Backdrop:

1. Due to heavy rains, the schools are off and RRJ, therefore, in RRS's office
2.  A conversation a long time ago about what does a PhD student do and how long it takes to finish etc.                         

When RRJ and RRS were walking back after lunch in the canteen, one of RRS's student (J) crossed them.

J: When mu is increasing rho is decreasing.
RRS: How is that possible?
J: Really! I will show you later.

Then J goes for his lunch

RRJ: When something is increasing, it is decreasing! How is this possible?
RRS: Not possible
RRJ: That is a problem. Answer should be found
RRS: Yes. He is the student. He should find the answer
RRJ: Then one more year. 6 years then. Which year is he in?
RRS: Third year.
RRJ: Only third year. Then maybe not sixth year.
RRS: Yes. He will finish in 5.
RRJ: What is his problem?
[RRS describes the problem]
RBR: Not fully understood, but ok.....
