Briefly explain the following statement from the text.
“The lack of determinism in quantum theory!”
उत्तर
The statement occurs in the text Adventure by Jayant Vishnu Narlikar. This statement is made by Prof. Gaitonde in response to the explanation of Catastrophic theory as explained by Rajendra. Rajendra was trying to rationalise the experiences of Prof. Gaitonde in which he witnessed an altogether new version of Indian History. According to the revelations made to Gaitonde, the Marathas emerged as victorious in the Battle of Panipat and extended influence over the entire country making India self-reliant in all respect. The Maratha Peshwas were gradually replaced by democratically elected bodies. Rajendra tried to explain this varied version by applying the catastrophic theory. The catastrophic theory postulates that there can be many alternative realities existing simultaneously. This theory has been developed on the basis of experiments on small systems like atom and their constituent particles. The physicists have observed that the behaviour of these systems cannot be predicted definitively even if all the physical laws governing those systems are known. That means there is a lack of determinism. This theory has been developed in Quantum physics and wonderfully explains phenomena like that experienced by Prof. Gaitonde was convinced by the explanation offered by Rajendra which could resolve the perplexities as presented before him in the face of two different versions of Indian history.

Read the passage carefully.
1. I remember my childhood as being generally happy and can recall experiencing some of the most carefree times of my life. But I can also remember, even more vividly, moments of being deeply frightened. As a child, I was truly terrified of the dark and getting lost. These fears were very real and caused me some extremely uncomfortable moments.
2. Maybe it was the strange way things looked and sounded in my familiar room at night that scared me so much. There was never total darkness, but a street light or passing car lights made clothes hung over a chair take on the shape of an unknown beast. Out of the corner of my eye, I saw curtains move when there was no breeze. A tiny creak in the floor would sound a hundred times louder than in the daylight and my imagination would take over, creating burglars and monsters. Darkness always made me feel helpless. My heart would pound and I would lie very still so that 'the enemy' wouldn't discover me.
3. Another childhood fear of mine was that I would get lost, especially on the way home from school. Every morning, I got on the school bus right near my home ‒ that was no problem. After school, though, when all the buses were lined up along the curve, I was terrified that I would get on the wrong one and be taken to some unfamiliar neighbourhood. I would scan the bus for the faces of my friends, make sure that the bus driver was the same one that had been there in the morning, and even then ask the others over and over again to be sure I was in the right bus. On school or family trips to an amusement park or a museum, I wouldn't let the leaders out of my sight. And of course, I was never very adventurous when it came to taking walks or hikes because I would go only where I was sure I would never get lost.
4. Perhaps, one of the worst fears I had as a child was that of not being liked or accepted by others. First of all, I was quite shy. Secondly, I worried constantly about my looks, thinking people wouldn't like me because I was too fat or wore braces. I tried to wear 'the right clothes' and had intense arguments with my mother over the importance of wearing flats instead of saddled shoes to school. Being popular was very important to me then and the fear of not being liked was a powerful one.
5. One of the processes of evolving from a child to an adult is being able to recognise and overcome our fears. I have learnt that darkness does not have to take on a life of its own, that others can help me when I am lost and that friendliness and sincerity will encourage people to like me. Understanding the things that scared us as children helps to cope with our lives as adults.
