Think about the text
1.) Pursuit of science is an exciting adventure. Do you agree? Can you compare this with other types of adventure like pursuit of sports? Share your views with your friends.
Answer: Yes, pursuit of science is an exciting adventure just like any other adventure. When we take up science as an exciting adventure, we focus on the journey and the process. Though we are unaware of the outcome, but the process gives happiness.
2.) Which sentences in the text suggest that the author was involved more in the theoretical research than in its application to the war craft?
Answer: I was absorbed in my problem; I enjoyed the mathematical challenge.
I did not give much thought to how it connects with the real life.
3.) “A paradox may refer to a person, a thing or a situation that has two opposite features and therefore seems strange.” In the light of this definition, how is ‘MAD’ a paradox? How could MAD affect the super power nations?
Answer: The acronym MAD stands for Mutually Assured Destruction. Nations used the nuclear weapons for protection of the people for the common fatal fate or for the reason of self-defense. But if the same weapons are used other than the previous given reason, then its outcome would lead only to destruction. It could destroy the whole nation.
4.) What was the ‘problem’ that the nuclear powers had faced? Was it a violation of the agreement or was it the detection of the violation? Explain briefly.
Answer: It was the issue of trust. Supposing that nations sign an agreement to stop the rest of the new nuclear weapons and the other participants violated this agreement and secretly made an underground nuclear explosion, then this could definitely lead to destruction.
5.) Why were the technical experts summoned by the three superpowers?
Answer: The three superpowers had enough nuclear bombs to destroy the others in the first strike. But in the 20 minutes it took for the rockets to reach their targets, the other side had plenty of time to launch retaliation strikes ensuring the destruction of their enemies only a few minutes later. The three superpowers were willing to come to an agreement to solve the problem so they summoned the technical experts.
6.) In which area did KeilisBorok’s theoretical knowledge have a direct application?
Answer: KeilisBorok was doing research on the theory of seismic waves which were tremors generated by an earthquake. It turned out that this problem had a direct connection with the theory of seismic waves since underground nuclear explosions produced earth tremors very similar to those generated by earthquakes.
7.) “Iron Curtain” is referred to as a barrier. It was outwardly difficult for the opposite sides of the iron curtain to find out the solution for the problem of violation of agreement. What was the reason?
Answer: Iron Curtain was a barrier. Since there was ongoing Cold War and there were political tensions hanging over, the scientists from the opposite sides gave up their differences and work together.
8.) How are the scientists able to work in spite of political and cultural differences?
Answer: In spite of political and cultural differences, the scientists were able to work together for the betterment of the mankind and their future. It was only possible with the help of respect to hard evidence and persistence self-criticism.
9.) Make a list of lessons that the writer learnt at the Geneva Summit.

1.) As a scientist, the author had people all over the world who think and interact the way he did. 2. He never to felt lonely abroad.
3.) It taught him that while there is science, there is hope of survival and well-being for all of us.
10.) Give a few examples which illustrate the writer’s stand that scientists are the most practical people in the world.
Answer: According to the writer, all new technologies, all new brands of industry from defence
to entertainment stem from fundamental research. Other examples include antibiotics, electronics, biotechnology, synthetic fibres, the green revolution, and genetic forensic diagnosis, etc. He is of the opinion that all the things come from the basic research and thus this shows that how the scientists are the most practical people in the world.
11.) Who will be headhunted by financial institutions and pharmaceutical industries? Why?
Answer: People trained in theoretical physics will headhunted by financial institutions. People trained in frontiers of biological research will become founders and directors in the pharmaceutical industry. Since these people have basic knowledge of science and have practical inputs with it so they will definitely headhunt.
12.) Some statements are given below. Are they true? Why / Why not. Discuss with your partner.
a) Money is more powerful than intellectual resources. Not true
Reason – Money doesn’t define anyone. Also there is guarantee of money. But what is forever is the wisdom and the intelligence that would help the mankind
