Science of Discworld

THE ROUNDWORLD PROJECT

ARCHCHANCELLOR RIDCULLY AWOKE FROM AN AFTERNOON NAP in which he had been crawling through a baking desert under a flamethrower sky, and found that this was more or less true.

Superheated steam whistled from the joints of the radiator in the corner. Ridcully walked over through the stifling air and touched it gently.

'Ouch! Damnation!'

Sucking his right hand and using his left hand to unwrap the scarf from his neck, he strode out into the corridor and what looked like Hell with the heat turned up. Steam rolled along the corridors, and from somewhere overhead came the once-heard-never-forgot-ten thwack of a high-energy magical discharge. Violet light filled the windows for a moment.

'Will someone tell me what the heck is going on?' Ridcully demanded of the air in general.

Something like an iceberg loomed out of the steam. It was the Dean.

'I would like to make it absolutely clear, Archchancellor, that this is nothing to do with me!'

Ridcully wiped away the sweat that was beginning to trickle down his forehead.

'Why are you standin' there in just your drawers, Dean?'

'I…well, my room is absolutely boiling hot...'

'I demand you put something on, man, you look thoroughly unhygienic!'

There was another crack of discharged magic. Sparks flew off the end of Ridcully's fingers.

'I felt that one!' he said, running back into his room.

Beyond the window, on the other side of the gardens, the air wavered over the High Energy Magic building. As the Archchancellor watched, the two huge bronze globes on its roof became covered in crawling, zig-zagging purple lines.

He hit the floor rolling, as wizards are wont to do, just before the shock of the discharge blew the windows in.

Melted snow was pouring off the rooftops. Every icicle was a streaming finger of water.

A large door bumped and scraped its way across the steaming lawns.

Tor goodness' sake, Dean, handle your end, can't you?'

The door skidded a little further.

'It's no good, Ridcully, it's solid oak!'

'And I'm very glad of it!'

Behind Ridcully and the Dean, who were inching the door for­ward largely by arguing with each other, the rest of the faculty crept forward.

The bronze globes were humming now, in the rapidly decreas­ing intervals between discharges. They had been installed, to general scoffing, as a crude method of releasing the occasional erratic build-up of disorganized magic in the building. Now they were outlined in unhealthy-looking light.

'And we know what that means, don't we, Mister Stibbons?' said Ridcully, as they reached the entrance to the High Energy Magic building.

'The fabric of reality being unravelled and leaving us prey to creatures from the Dungeon Dimensions, sir?' mumbled Stibbons, who was trailing behind.

'That's right, Mister Stibbons! And we don't want that, do we, Stibbons?'

'No, sir.'

'No, sir! We don't, sir!' Ridcully roared. 'It'll be tentacles all over the place again. And none of us wants tentacles all over the place, do we?'

'No, sir.'

'No, sir! So switch the damned thing off_t sir!'

'But it'd be certain death to go into...' Ponder stopped, swallowed and restarted. 'In fact it would be uncertain death to go into the squash court at the moment, Archchancellor. There must be million of thaums of random magic in there! Anything could happen!'

Inside the HEM the ceiling was vibrating. The whole building seemed to be dancing.

'They certainly knew how to build, didn't they, when they built the old squash court,' said the Lecturer in Recent Runes, in an admiring tone of voice. 'Of course, it was built to contain large amounts of magic ...'

'Even if we could switch it off, I don't think that'd be such a good idea,' said Ponder.

'Sounds a lot better than what's happening now,' said the Dean.

'But is falling through the air better than hitting the ground?' said Ponder.

Ridcully sucked in his breath between his teeth.

'That's a point,' he said. 'Could be something of an implosion, I suppose. You can't just stop something like this. Something bad would happen.'

'The end of the world?' quavered the Senior Wrangler.

'Probably just this part of it,' said Ponder.

'Are we talking here about a sort of huge valley about twenty miles across with mountains all round it?' said Ridcully, staring at the ceiling. Cracks were zig-zagging across it.

'Yes, sir, I'm wondering if whoever tried this at Loko actually did manage to switch it off ...'

The walls groaned. There was a rattling noise behind Ponder. He recognized it, even above the din. It was the sound of HEX reset­ting its writing device. Ponder always thought of it as a kind of mechanical throat-clearing.

The pen jerked in its complex network of threads and springs, and then wrote:

+++ This May Be Time For The Roundworld Project +++

'What are you talking about, man?' snapped Ridcully, who'd never quite understood what HEX was.

'Oh, that? That's been around for ages,' said the Dean. 'No one's ever taken it seriously. It's just a thought experiment. You couldn't do it. It's completely absurd. It needs far too much magic.'

'Well, we've got far too much magic,' said Ridcully. 'Right now we need to use it up.'

There was a moment's silence. That is, the wizards were silent. Overhead, magic flared into the sky with a sound like roaring gas.

'Can't let it build up here,' Ridcully went on. 'What's the Roundworld project then?'

'It was, er ... there was once some suggestion that it might be possible to create a ... an area where the laws of magic don't apply,' said Ponder. 'We could use it to learn more about magic.'

'Magic's everywhere? said Ridcully. 'It's part of what everywhere is'

'Yes, sir,' said Ponder, watching the Archchancellor carefully.

The ceiling creaked.

'What use would it be, anyway?' said Ridcully, still thinking aloud.

'Well, sir, you could ask what use is a new-born child ...'

'No, that's not the sort of question I ask,' said Ridcully. 'And it's a highly suspicious one, too.'

The wizards ducked as the latest discharge crackled overhead. It was followed by a louder explosion.

'I think the balls have just exploded, sir,' said Ponder.

'All right, then, how long would the project take to set up?' said Ridcully.

'Months,' said the Dean firmly.

'We've got about ten seconds to the next discharge, sir,' said Ponder. 'Only ... now the balls have gone it will simply earth itself...'

'Ah. Oh. Really? Well, then ...' Ridcully looked around at his fel­low wizards as the wall began to shake again. 'It's been nice knowing you. Some of you. One or two of you, anyway ...'

The whine of increasing magic rose in pitch.

The Dean cleared his throat.

'I'd just like to say, Mustrum,' he began.

'Yes, old friend?'

'I'd just like to say ... I think I'd have made a much better Archchancellor than you.'

The whine stopped. The silence twanged. The wizards held their breath.

Something went 'ping'.

A globe about a foot across hung in the air between the faculty. It looked like glass, or the sheen of a pearl without the pearl itself.

From the squash court next door there was, instead of the wild roar of disorganized thaums, the steady thrum-thrum of purpose.

'What the heck is that ?' said Ridcully, as the wizards unfolded themselves.

HEX rattled. Ponder picked up the piece of paper.

'Well, according to this, it's the Roundworld Project,' he said. 'And it's absorbing all the energy from the thaumic pile.'

The Dean brushed some dust off his robe.

'Nonsense,' he said. 'Takes months. Anyway, how could that machine possibly know the spells?'

'Mr Turnipseed did copy in a lot of the grimoires last year,' said Ponder. 'It's vital that HEX knows basic spell structure, you see .,.'

The Senior Wrangler peered irritably at the sphere.

'Is this all it is?' he said. 'Doesn't seem much for all that effort.'

There was a frightening moment as the Dean walked up to the sphere and his nose, enormously magnified, appeared in it.

'Old Archchancellor Bewdley devised it,' he said. 'Everyone said it was impossible ...'

'Mr Stibbons?' said Ridcully.

'Yes, sir?'

'Are we in danger of blowing up at the moment?'

'I don't think so, sir. The ... project is sucking up everything.'

'Shouldn't it be glowing, then? Or something? What's in there?'

HEX wrote: +++ Nothing +++

'All that magic's going into empty space?'

+++ Empty Space Is Not Nothing, Archchancellor. There Is Not Even Empty Space Inside The Project. There Is No Time For It To Be Empty In +++

'What's it got in it, then?'

+++ I Am Checking +++, HEX wrote patiently.

'Look, I can stick my hand right in it,' said the Dean.

The wizards watched in horror. The Dean's fingers were visible, darkly, within the sphere, outlined in thousands of tiny sparkling lights.

'That was a really very foolish thing you just did,' said Ridcully. 'How did you know it wasn't dangerous?'

'I didn't,' said the Dean cheerfully, 'It feels ... cool. And rather chilly. Prickly, in a funny sort of way'

HEX rattled. Ponder walked back and looked down at the paper. 'It almost feels sticky when I move my fingers,' said the Dean.

'Er ... Dean?' said Ponder, stepping back carefully. 'I think it would be a really good idea if you pulled your hand out very, very carefully and really very soon.'

'That's odd, it's beginning to tingle...'

'Right now, Dean! Right now!'

For once, the urgency in Ponder's voice got through the Dean's cosmic self-confidence. He turned to argue with Ponder Stibbons just a moment before a white spark appeared in the centre of the sphere and began to expand rapidly.

The sphere flickered.

'Anyone know what caused that?' said the Senior Wrangler, his face bathed in the growing light of the Project.

'I think,' said Ponder slowly, holding up HEX's write-out, 'it was Time and Space starting to happen.'

In HEX's careful writing, the words said: +++ In The Absence Of Duration And Dimension, There Must Be Potentiality. +++

And the wizards looked upon the universe that was growing within the little sphere and spake amongst themselves, saying, 'It's rather a small one, don't you think? Is it dinner time yet?'

Later on, the wizards wondered if the new universe might have been different if the Dean had waggled his fingers in a different way. Perhaps, within it, matter might have naturally formed itself into, say, garden furniture, or one giant nine-dimensional flower a trillion miles across. But Archchancellor Ridcully pointed out that this was not very useful thinking, because of the ancient principle of WYGIWYGAINGW.
