Q: The Continuum didn't think you had it in you, Jean-Luc. But I knew you did...We wanted to see if you had the ability to expand your mind and your horizons. And for one brief moment, you did.Picard: When I realized the paradox.Q: Exactly. For that one fraction of a second, you were open to options you had never considered. That is the exploration that awaits you. Not mapping stars and studying nebula, but charting the unknown possibilities of existence.

If, years later, I do use the slit detector to observe which way the electron went, it will mean that many years earlier the electron must have passed through one slit or the other. But if I don't use the "slit detector," then the electron must have passed through both slits. This is, of course, extremely weird. My actions at the beginning of the twenty-first century can change what happened thousands of years ago when the electron began its journey. It seems that just as there are multiple futures, there are also multiple pasts, and my acts of observation in the present can decide what happened in the past. As much as it challenges any hope of ever really knowing the future, quantum physics asks whether I can ever really know the past. It seems that the past is also in a superposition of possibilities that crystallize only once they are observed.

The Great Unknown: Seven Journeys to the Frontiers of Science

We know from several statements of Knecht's that he wanted to write the former Master's biography, but official duties left him no time for such a task. He had learned to curb his own wishes. Once he remarked to one of his tutors: "It is a pity that you students aren't fully aware of the luxury and abundance in which you live. But I was exactly the same when I was still a student. We study and work, don't waste much time, and think we may rightly call ourselves industrious__ut we are scarcely conscious of all we could do, all that we might make of our freedom. Then we suddenly receive a call from the hierarchy, we are needed, are given a teaching assignment, a mission, a post, and from then on move up to a higher one, and unexpectedly find ourselves caught in a network of duties that tightens the more we try to move inside it. All the tasks are in themselves small, but each one has to be carried out at its proper hour, and the day has far more tasks than hours. That is well; one would not want it to be different. But if we ever think, between classrooms, Archives, secretariat, consulting room, meetings, and official journeys__f we ever think of the freedom we possessed and have lost, the freedom for self-chosen tasks, for unlimited, far-flung studies, we may well feel the greatest yearning for those days, and imagine that if we ever had such freedom again we would fully enjoy its pleasures and potentialities.
