This was a good thing, as Piali took an interest in her too, and over the next several months, courted her in his peculiar way; he came to the zawiyya, and got to know her house family there, and listened to her describe her problems with her studies in history, while also going on at nearly intolerable length about his problems in physics and at the institute. He shared with her a propensity for the cafe life as well, and did not seem to care about the assorted indiscretions she had committed since her arrival in Nsara; he ignored all that, and concentrated on things of the mind, even when sitting in a cafe sipping a brandy, and writing all over his napkins, one of his peculiar habits. They talked about the nature of history for hours, and it was under the impact of his deep scepticism, or materialism, that she finally completed the shift in the emphasis of her study from history to archaeology, from texts to things convinced, in part, by his argument that texts were always just people's impressions, while objects had a certain unchangeable reality to them. Of course the objects led directly to more impressions, and meshed with them in the web of proofs that any student of the past had to present in order to make a case; but to start with the tools and buildings rather than the words of the past were indeed a comfort to Budur. She was tired of distilling brandy. She began consciously to take on some of the inquisitiveness about the real world that Idelba had always exhibited, as a way of honouring her memory. She missed Idelba so much that she could not think of it directly, but had to parry it by homages such as these, invoking Idelba's presence by her habits, as if becoming a kind of Madam Sururi. It occurred to her more than once that there were ways in which we know the dead better than the living, because the actual person is no longer there to distract our thinking about them.
Following these various trains of thought, there also began to occur to Budur a great number of questions that connected her work with Idelba's as she understood it, as she considered physical changes in the materials used in the past: chemical or physical or qi or qileak changes, that might be used as clocks, buried in the texture of the materials used. She asked Piali about this, and he quickly mentioned the shift over time in the types of particulates in the heartknots and shells, so that, for instance, lifering fourteens within a body would, after the death of an organism, begin slowly to fall back to lifering twelves, beginning about fifty years after the death of an organism and continuing for about a hundred thousand years, until all the lifering in the material was back to twelves, and the clock would stop functioning.
This would be long enough to date most human activities, Budur thought. She and Piali began to work on the method together, enlisting the help of other scientists at the institute. The idea was taken up and extended by a team of Nsarene scientists that grew by the month, and the effort quickly became global as well, in the usual way of science. Budur had never studied harder.
Thus it was that over time she became an archaeologist, working among other things on dating methods, with the help of Piali. In effect she had replaced Idelba as Piali's partner, and he had therefore moved part of his work to a different field, to accommodate what she was doing. His method of relating to someone was to work with them; so even though she was younger, and in a different field, he simply adjusted and continued in his habitual way. He also continued to pursue his studies in atomic physics, of course, collaborating with many colleagues at the laboratories of the institute, and some of the scientists at the wireless factory on the outskirts of the city, whose lab was now beginning to match the madressa and the institute as a centre of research in pure physics.
