His first day at college..he walks on the road that led to his dept.He hears a voice

Senior tells something in Vivek’s ears…ragasiyam..secret!!!
Vivek: Sure..naa varen!
At 1 PM after lunch he meets the same senior..
Vivek: Am not able to find that gal..veena…! : (
Senior again tells some secret…
He goes away and meets the senior again at 3 PM.
Vivek: Assuming that the unknown gal is Veena, it looks like the gal’s characteristics match with Veena’s characteristics on a probability of 0.3 on a conditional probability that gal’s aalu is same as Veena’s Aalu which still holds a 0.5 probability.
Again the same thing happens.. Senior advises something in Vivek’s ears..Vivek goes away..
He meets the senior again at 5 PM.
Vivek: I am clear ..100 %.. that gal may be Veena or may not be Veena..That gal’s aalu may be Veena’s aalu or may not be ..But having found the fact that Veena has an aalu ..I should change my (re)search topic my premise..or gal..
Senior: DO you now understand what is research??? Who I am??? And vanishes away..
Vivek: Thalai!!! Neenga engeyo poiteenga!!!>…..
