through the cold rock alleys between home and the laboratory. He carried a box
of drinker files and two coils of copper tubing and looked comparatively
happy.
William was a swarthy stick of a man, two metres tall, black eyes deep-set,
long narrow chin, lips thin, brows and hair dark as space, with a deep shadow
on his jaw. He was seldom calm or quiet, except when working; he could be rude
and abrasive. Set loose in a meeting, or conversing on the lunar corn net, he
sometimes seemed contentious to the point of self-destruction, yet still the
people closest to him loved and respected him. Some of the Sandoval engineers
considered William a genius with tools and machines, and on those rare
occasions when I was privileged to see his musician's hands prodding and
persuading, seducing all instrumentality, designing as if by willing consensus
of all the material parts, I could only agree; but I loved him much less than
I respected him.
In her own idiosyncratic way, Rho was crazy about him; but then, she was just
as driven as William. It was a miracle their vectors added.
We matched step. 'Rho's back from Earth. She's flying in from Port Yin,' I
said.
'Got her message,' William said, bouncing to touch the rock roof three metres
overhead. His glove brought down a few lazy drifts of foamed rock. 'Got to get
the arbeiters to spray that.' He used a distracted tone that betrayed no real
intent to follow through. 'I've finally straightened out the QL, Micko. The
interpreter's making sense. My problems are solved.'
'You always say that before some new effect cuts you down.' We had come to the
large, circular, white ceramic door that marked the entrance to the Ice Pit
and stopped at the white line that William had crudely painted there, three
years ago. The line could be crossed only on his invitation.
The hatch opened. Warm air poured into the corridor; the Ice Pit was always
warmer than ambient, being filled with so much equipment. Still, the warm air
smelled cold; a contradiction I had never been able to resolve.
'I've licked the final source of external radiation,' William said. 'Some
terrestrial metal doped with twentieth-century fallout.' He zipped his hand
away. 'Replaced it with lunar steel. And the QL is really tied in. I'm getting
straight answers out of it - as straight as quantum logic can give. Leave me
my illusions.'
'Sorry,' I said. He shrugged magnanimously. 'I'd like to see it in action.'
He stopped, screwed up his face in irritation, then slumped a bit. 'I'm sorry,
Mickey. I've been a real wart. You fought for it, you got it for me, you
deserve to see it. Come on.'
I followed William over the line and across the forty-metre-long, two-metre-
wide wire and girder bridge into the Ice Pit.
William walked ahead of me, between the force disorder pumps. I stopped to
look at the ovoid bronze toruses mounted on each side of the bridge. They
reminded me of abstract sculptures, and they were among the most sensitive and
difficult of William's tools, always active, even when not connected to
William's samples.
Passing between the pumps, I felt a twitch in my interior, as if my body were
a large ear listening to something it could barely discern: an elusive,
sucking silence. William looked back at me and grinned sympathetically.
'Spooky feeling, hm?'
'I hate it,' I said.
'So do I, but it's sweet music, Micko. Sweet music indeed.' Beyond the pumps
and connected to the bridge by a short, narrow walkway, hung the Cavity,
enclosed in a steel Faraday cage. Here, within a metre-wide sphere of perfect
orbit-fused quartz, the quartz covered with a mirror coating of niobium, were
eight thumb-sized ceramic cells, each containing approximately a thousand
atoms of copper. Each cell was surrounded by its own superconducting
