To speculate about the future is one of the most basic qualities of man. It involves two aspects: one is to forecast what the future development will be and the other is to determine in what approximate period of time it is going to take place. To make such a prognosis means to learn from the past experience and to extrapolate the knowledge into the future. Recently, however, the rate of change has been so great as to make it difficult to learn from experience, at least as far as the time factor is concerned. To take but one example, a prediction of man's possible landing on the Moon around the turn of the century was made as late as 1961, only 8 years before the actual event! So, to be on the safe side, we had better leave time to take care of itself, and concentrate our attention on what the future may be like. There is yet another problem involved: are we to accept submissively any possible course of events, or are we to work for a future most suited for most people? The choice is to be made, at different levels, by every individual and by every society.

What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry or any other science? What are their special methods of thinking and acting? What qualities do we usually expect them to possess? To begin with, we expect a successful scientist to be full of curiosity - he wants to find out how and why the universe works. He usually directs his attention towards problems which have no satisfactory explanation, and his curiosity makes him look for the underlying relationships even if the data to be analysed are not apparently interrelated. He is a good observer, accurate, patient and objective. Furthermore, he is not only critical of the work of others, but also of his own, since he knows man to be the least reliable of scienrific instruments.

And to conclude, he is to be highly imaginative since he often looks for data which are not only complex, but also incomplete.

1. What are the two aspects of speculation about the future? 2. What are the two steps of any prognosis? 3. Why has it been so difficult recently to make any predictions concerning the future development? 4. What example is cited to illustrate the difficulty? 5. Does the author make any suggestions concerning this difficulty? Why does he suggest this? 6. What dilemma are we faced with and what choice is to be made by every individual and every society? 7. What are Russian equivalents of: before the actual event, leave time to take care of itself, what the future may be like? 8. What qualities do we expect to find in a successful scientist? 9. Why do we say that a successful scientist is full of curiosity? 10. Why is it difficult to see the underlying relationships? 11. Why is he critical of his own work? 12. Why is it necessary for him to be highly imaginative? 13. Give a Russian equivalent of the title and of the data analysed and the data to be analysed.
