Briefly explain the following statement from the text.
“The lack of determinism in quantum theory!”
Advertisements
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.

The passage given below is on Kabbadi. Read the passage and complete the activities that follow.
Kabbadi (கபடி - in Tamil) is a contact team sport that originated in Tamil Nadu, India. It is the national sport of Bangladesh. It is also popular in South Asia and is the state game of the Indian states of Tamil Nadu, Kerala, Andhra Pradesh, Bihar, Haryana, Karnataka, Maharashtra, Punjab, and Telangana.
Kabbadi is played between two teams of seven players: the objective of the game is for a single player on offence referred to as a 'raider', to run in to the opposing teams half of a court, tag out as many of their defenders as possible, and return to their own half of the court–all without being tackled by the defenders. Points are scored for each player tagged by the raider, while the opposing team earns a point for stopping the raider. Players are taken out of the game if they are tagged or tackled, but can be 'revived' for each point scored by their team from a tag or tackle. The raider should hold his breath and utter the words like 'kabbadi kabbadi, hututu hututu, chadu kudu' etc. while the opponents try to catch him. If he stops uttering these words, he is considered out.
The game is known by its regional names in different parts of the subcontinent, such as Kabbadi or Chedugudu in Andhra Pradesh, Kabbadi in Kerala and Telangana, Hadudu in Bangladesh, Bhavatik in Maldives, Kauddi or Kabbadi in the Punjab Region, Hu-Tu-Tu in Western India and Hu-Do-Do in Eastern India and Chadakudu in South India. The highest governing body of Kabbadi is the International Kabbadi Federation.

“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. While 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. |
