The Year's Best Science Fiction, Vol. 20

In all this sensing activity, remarkably little physical harm was done to the extended organism itself. The biomass sensed the approach of the probes and rearranged itself so that they passed through with little obstruction, even those scything lines that reached into the water. Energy was obviously being consumed to avoid the organism sustaining damage, and by implication the measurements must therefore have had some effect on the node’s information processing efficiency. The effect was likely to be small, however, and since the node was already subject to constant changes in its architecture-some probably intentional, and some probably forced on it by other factors in its environment-there appeared to be little point in worrying about the harm caused by the human investigators. Ultimately, so much was still guesswork. Although the swimmer teams had learned a great deal about the Pattern Jugglers’ encoded information, almost everything else about them-how and why they stored the neural patterns, and to what extent the patterns were subject to subsequent postprocessing-remained unknown. And those were merely the immediate questions. Beyond that were the real mysteries, which everyone wanted to solve, but were simply beyond the scope of immediate academic study. What they would learn today could not be expected to shed any light on those profundities. A single data point-even a single clutch of measurements-could not usually prove or disprove anything. But nonetheless it might later turn out to play a vital role in some chain of argument, even if it was only in the biasing of some statistical distribution closer to one hypothesis than another. Science, as Naqi had long since realised, was as much a swarming, social process as it was something driven by ecstatic moments of personal discovery.

It was something she was proud to be part of.

The spiral sweep continued uneventfully, the airship chugging around in a gently widening circle. Morning shifted to early afternoon, and then the sun began to climb down toward the horizon, bleeding pale orange into the sky through soft-edged cracks in the cloud cover. For hours Naqi and Mina studied the incoming results, the ever-sharper scans of the node appearing on screens throughout the gondola. They discussed the results cordially enough, but Naqi could not stop thinking about Mina’s betrayal. She took a spiteful pleasure in testing the extent to which her sister would lie, deliberately forcing the conversation around to Dr. Sivaraksa and the project he steered.

“I hope I don’t end up like one of those deadwood bureaucrats,” Naqi said, when they were discussing the way their careers might evolve. “You know, like Sivaraksa.” She observed Mina pointedly, yet giving nothing away. “I read some of his old papers; he used to be pretty good once. But now look at him.”

“It’s easy to say that,” Mina said. “But I bet he doesn’t like being away from the frontline any more than we would. But someone has to manage these big projects. Wouldn’t you rather it was someone who’d at least been a scientist?”

“You sound like you’re defending him. Next you’ll be telling me you think the Moat is a good idea.”

“I’m not defending Sivaraksa,” Mina said. “I’m just saying…” She eyed her sister with a sudden glimmer of suspicion. Had she guessed that Naqi knew? “Never mind. Sivaraksa can fight his own battles. We’ve got work to do.”

“Anyone would think you were changing the subject,” Naqi said. But Mina was already on her way out of the gondola to check the equipment again.

At dusk the airship arrived at the perimeter of the node, completed one orbit, then began to track inward again. As it passed over the parts of the node previously mapped, time-dependent changes were highlighted on the displays: arcs and bands of red superimposed against the lime and turquoise false-colour of the mapped structures. Most of the alterations were minor: a chamber opening here or closing there, or a small alteration in the network topology to ease a bottleneck between the lumpy subnodes dotted around the floating island. Other changes were more mysterious in function, but conformed to types seen in other studies. They were studied at enhanced resolution, the data prioritised and logged.

It looked as if the node was large but in no way unusual.
