The lack of determinism in quantum theory!”

Answer in Brief
Advertisements

Solution

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.

"I don't believe in taking the right decisions. I take decisions, I take decisions and then make them right:' One of them make them right. One of Ratan Tata's inspiring words which made me dream beyond shadows. I feel fortunate that I discovered him in the early stage of my life and now I am using his teachings to mould my future the way I want.

Even though Ratan Tata was born into a very posh family in India, he never took money and power for granted. He graduated from Riverdale country from New York, Ratan Tata began his career in the Tata Group working on the shop floor of Tata Steel. After working for almost 10 years he was appointed as the director-in-charge of the National Radio and Electronics Company Limited (NELCO) in order to help its struggling finances. He worked hard to build a better consumer electronics division but the economic recession and union strikes prevented him from achieving success and this success helped Tata to be appointed as the chairman of the Tata Group of companies. He started with a very basic job in his father's company and today he owns a billion dollar company.

The tag of greatness does not come without making any sacrifices and this tag on Ratan Tata suits to its best.

Tata group launched its passenger car Tata Indica in the year 1998 but Tata Indica was a failure in its first year and the experiment seemed to be failing. Many people started advising Ratan Tata that he should sell the passenger car business. Ratan Tata also agreed to this and a proposal was given to Ford. they showed interest too. The three-hour meeting at Ford headquarters in Detroit, chairman of Ford (Bill Ford) said to Ratan Tata, "Why did you enter in the passenger car business when you were not knowing of it. It will be a favour if we buy this business from you."

Ratan Tata decided to move back home. Whi le travelling he was very tense as the feeling of being insulted was on his mind. After earlier failures, Tata Motors did well with its business of passenger cars but in the same period, Ford did very bad. In 2008 when Ford was on it way of bankruptcy, Tata Group offered Ford to buy its luxury car brand, Jaguar Land Rover. Ford arrived in Mumbai for the meeting. In the meeting, Bill Ford said to Ratan Tata, you are doing a big favour for us by buying-Jaguar-Land Rover is now owned by Tata Group and is currently making profits.

The call of the seas has always found an echo in me. Not being rich enough to roam in a private yacht, I have taken the poor man's way out. I swim across them. I have always been fascinated by the Indian ocean, whether at Mumbai, at Puri or at Gopalpur. I have swam in all these places and have felt the thrill. But the idea of swimming the Palk Strait did not occur to me until after I swam in the English channel. Steeped in the history and tradition of this nation, practically unconquered. teaming with hair-raising hazards, the sea between India and Sri Lanka had all the elements of challenge, danger and difficulty that tempted me. By the way, for preparation, I continued a strict and rigorous course of training which began in 1960. I also had to collect a comprehensive range of facts and information about this sea. Neither of these was easy.

Despite all the information I had gathered, I soon found that very little was known about the Palk Strait, especially about the tides and currents. Everything about the English channel is known-there is the Channel Swimming Association, there are trained pilots there are wants to be hired, accurate weather forecasts, dependable tide tables and every other form of assistance was readily available. All that one needed was money. Here in the Palk Strait one has to find out firstly from where information could be obtained and then decide how much of it could be incorrect or misleading!
