'It's tempting to think that we would do better, if we were transported a thousand years hence. Surely the fundamental scientific discoveries have already been made, though there will be major improvements in technology, will there be any devices, anything as magical and incomprehensible to us as a pocket calculator or a video camera would have been to Isaac Newton?'

'Perhaps our age is indeed sundered from all those that have gone before. Telecommunications, the ability to record images and sounds once irrevocably lost, the conquest of the air and space – all these have created a civilization beyond the wildest fantasies of the past. And equally important, Copernicus, Newton, Darwin and Einstein have so changed our mode of thinking and our outlook on the universe that we might seem almost a new species to the most brilliant of our predecessors.'

'And will our successors, a thousand years from now, look back on us with the same pity with which we regard our ignorant, superstitious, disease-ridden, short-lived ancestors? We believe that we know the answers to questions that they could not even ask: but what surprises does the Third Millennium hold for us?'

'Well, here it comes -'

A great bell began to toll the strokes of midnight. The last vibration throbbed into silence...

'And that's the way it was – good-bye, wonderful and terrible twentieth century...'

Then the picture broke into a myriad fragments, and a new commentator took over, speaking with the accent which Poole could now easily understand, and which immediately brought him up to the present.

'Now, in the first minutes of the year three thousand and one, we can answer that question from the past...'

'Certainly, the people of 2001 who you were just watching would not feel as utterly overwhelmed in our age as someone from 1001 would have felt in theirs. Many of our technological achievements they would have anticipated; indeed, they would have expected satellite cities, and colonies on the Moon and planets. They might even have been disappointed, because we are not yet immortal, and have sent probes only to the nearest stars...'

Abruptly, Indra switched off the recording.

'See the rest later, Frank: you're getting tired. But I hope it will help you to adjust.'

'Thank you, Indra. I'll have to sleep on it. But it's certainly proved one point.'

'What's that?'

'I should be grateful I'm not a thousand-and-oner, dropped into 2001. That would be too much of a quantum jump: I don't believe anyone could adjust to it. At least I know about electricity, and won't die of fright if a picture starts talking at me.'

I hope, Poole told himself, that confidence is justified. Someone once said that any sufficiently advanced technology is indistinguishable from magic. Will I meet magic in this new world – and be able to handle it?

'I'm afraid you'll have to make an agonizing decision,' said Professor Anderson, with a smile that neutralized the exaggerated gravity of his words.

'I can take it, Doctor. Just give it to me straight.'

'Before you can be fitted with your Braincap, you have to be completely bald. So here's your choice. At the rate your hair grows, you'd have to be shaved at least once a month. Or you could have a permanent.'

'How's that done?'

'Laser scalp treatment. Kills the follicles at the root.'

'Hmm... is it reversible?'

'Yes, but that's messy and painful, and takes weeks.'

'Then I'll see how I like being hairless, before committing myself. I can't forget what happened to Samson.'

'Who?'

'Character in a famous old book. His girl-friend cut off his hair while he was sleeping. When he woke up, all his strength had gone.'

'Now I remember – pretty obvious medical symbolism!'

'Still, I wouldn't mind losing my beard. I'd be happy to stop shaving, once and for all.'

'I'll make the arrangements. And what kind of wig would you like?'

Poole laughed.

'I'm not particularly vain – think it would be a nuisance, and probably won't bother. Something else I can decide later.'

That everyone in this era was artificially bald was a surprising fact that Poole had been quite slow to discover; his first revelation had come when both his nurses removed their luxuriant tresses, without the slightest sign of embarrassment, just before several equally bald specialists arrived to give him a series of micro-biological checks. He had never been surrounded by so many hairless people, and his initial guess was that this was the latest step in the medical profession's endless war against germs.

Like many of his guesses, it was completely wrong, and when he discovered the true reason he amused himself by seeing how often he would have been sure, had he not known in advance, that his visitors' hair was not their own. The answer was: seldom with men, never with women; this was obviously the great age of the wig-maker.

Professor Anderson wasted no time: that afternoon the nurses smeared some evil-smelling cream over Poole's head, and when he looked into the mirror an hour later he did not recognize himself. Well, he thought, perhaps a wig would be a good idea, after all...

The Braincap fitting took somewhat longer. First a mould had to be made, which required him to sit motionless for a few minutes until the plaster set. He fully expected to be told that his head was the wrong shape when his nurses – giggling most unprofessionally – had a hard time extricating him. 'Ouch that hurt!' he complained.

Next came the skull-cap itself, a metal helmet that fitted snugly almost down to the ears, and triggered a nostalgic thought – wish my Jewish friends could see me now! After a few minutes, it was so comfortable that he was unaware of its presence.

Now he was ready for the installation – a process which, he realized with something akin to awe, had been the Rite of Passage for almost all the human race for more than half a millennium.

'There's no need to close your eyes,' said the technician, who had been introduced by the pretentious title of 'Brain Engineer' – almost always shortened to 'Brainman' in popular usage. 'When Setup begins, all your inputs will be taken over. Even if your eyes are open, you won't see anything.'

I wonder if everyone feels as nervous as this, Poole asked himself. Is this the last moment I'll be in control of my own mind? Still, I've learned to trust the technology of this age; up to now, it hasn't let me down. Of course, as the old saying goes, there's always a first time...

As he had been promised, he had felt nothing except a gentle tickling as the myriad of nanowires wormed their way through his scalp. All his senses were still perfectly normal; when he scanned his familiar room, everything was exactly where it should be.

The Brainman – wearing his own skull-cap, wired, like Poole's, to a piece of equipment that could easily have been mistaken for a twentieth-century laptop computer – gave him a reassuring smile.

'Ready?' he asked.

There were times when the old cliche´s were the best ones.

'Ready as I'll ever be,' Poole answered.

Slowly, the light faded – or seemed to. A great silence descended, and even the gentle gravity of the Tower relinquished its hold upon him. He was an embryo, floating in a featureless void, though not in complete darkness. He had known such a barely visible, near ultra-violet tenebrosity, on the very edge of night, only once in his life when he had descended further than was altogether wise down the face of a sheer cliff at the outer edge of the Great Barrier Reef. Looking down into hundreds of metres of crystalline emptiness, he had felt such a sense of disorientation that he experienced a brief moment of panic, and had almost triggered his buoyancy unit before regaining control. Needless to say, he had never mentioned the incident to the Space Agency physicians...
