Blog 8: “Dear Zindagi” and mutual induction

One of the good movies which I have seen in recent past is Shahrukh Khan and Alia Bhat’s “Dear Zindagi”..!


A wonderful movie showing life of a young girl, her struggle, aspirations and stresses she goes through. Taking help of a psychiatrist, who helps her conquer her fears and guides her through a lesson, to love life..!! The part that I remember the most is his chair, which solely belongs to him and squeaks if any other person sits on it. The classic scene in this movie is the one in which, he sits on the chair, towards the end of the movie, and it squeaks.. indicating that the personality of him has changed.. to someone the chair doesn’t recognise. It is shown to be the effect of the chirpy, lively girl who is his patient. His personality gets modified, as well, while treating her..!!

We see such effects, so often in our everyday life. An influential person changes the generation of people who follow him/her. A charismatic person imbibes varied characters in the people around him/her, touching their lives…. But there is a difference.. the effect in the above examples is one way. While “Dear Zindagi” shows a two way effect..

I thought of such things in Physics as well. We have seen mutual induction, isn’t it? It says that whenever there is a conductor coil, carrying alternating current through it, it creates magnetic field around it… very similar to the psychiatrist, who has a great persona and trying to heal the patients coming to him. As long as the patient’s interaction zone is not too close, it works fine and as a simple therapy. However, if another conductor coil comes in close proximity to this coil, the magnetic lines of force of the current carrying conductor interfere with the second coil. The second coil, in our case is Alia Bhat’s character. As that happens, the field is induced in this coil as well, changing the performance of the coil, which otherwise was “lifeless”. That’s interesting, I think..!!


Secondly, a Lenz’s law states, whenever current is induced in a conductor, due to its own flux, its direction is such that it tries to oppose the cause. This means, the induced current changes the original character of the coil..! On similar lines, the character of Shahrukh Khan in this movie changes, due to his own therapy and its effect on his patient, Alia..! The only condition is that the acquaintance has to be friendlier and there has to be a connection between two personalities, to make this magic work. This can happen between two close friends, or between two people who are able to connect to each other, at an intellectual level, very well. The induction effect is an outcome of mutual respect, faith and affection towards the thought processes of each other.

Interesting, I guess..!! Maybe the Heisenberg’s uncertainty principle can say more.. Since it does say that while you measure one parameter, there is an error in the other, i.e., the other parameter changes… it would be rather difficult to connect these concepts.., but one can always try..

Curiosities helps us relate two totally different episodes in a magical way.. well, some may agree, and few may disagree too.. but to pen it down is important..!!

  1. I personally like this movie very much.But as a science student I couldn’t relate my thoughts with a movie.This article taught me how to do that.Thank you ma’am for this wonderful article.
