Pyramids

No-one seemed to be interested in stopping them as they helped each other through the doorway and out into the mad night.

'It helps if you shut your eyes,' said Ptraci.

Teppic tried it. It worked. A stretch of courtyard that his eyes told him was a quivering rectangle whose sides twanged like bowstrings became, well, just a courtyard under his feet.

'Gosh, that was clever,' he said. 'How did you think of that?'

'I always shut my eyes when I'm frightened,' said Ptraci.

'Good plan.'

'What's happening?'

'I don't know. I don't want to find out. I think going away from here could be an amazingly sensible idea. How do you make a camel kneel, did you say? I've got any amount of sharp things.'

The camel, who had a very adequate grasp of human language as it applied to threats, knelt down graciously. They scrambled aboard and the landscape lurched again as the beast jacked itself back on to its feet.

The camel knew perfectly well what was happening. Three stomachs and a digestive system like an industrial distillation plant gave you a lot of time for sitting and thinking.

It's not for nothing that advanced mathematics tends to be invented in hot countries. It's because of the morphic resonance of all the camels, who have that disdainful expression and famous curled lip as a natural result of an ability to do quadratic equations.

It's not generally realised that camels have a natural aptitude for advanced mathematics, particularly where they involve ballistics. This evolved as a survival trait, in the same way as a human's hand and eye co-ordination, a chameleon's camouflage and a dolphin's renowned ability to save drowning swimmers if there's any chance that biting them in half might be observed and commented upon adversely by other humans.

The fact is that camels are far more intelligent than dolphins19.

They are so much brighter that they soon realised that the most prudent thing any intelligent animal can do, if it would prefer its descendants not to spend a lot of time on a slab with electrodes clamped to their brains or sticking mines on the bottom of ships or being patronised rigid by zoologists, is to make bloody certain humans don't find out about it. So they long ago plumped for a lifestyle that, in return for a certain amount of porterage and being prodded with sticks, allowed them adequate food and grooming and the chance to spit in a human's eye and get away with it.

And this particular camel, the result of millions of years of selective evolution to produce a creature that could count the grains of sand it was walking over, and close its nostrils at will, and survive under the broiling sun for many days without water, was called You Bastard.

And he was, in fact, the greatest mathematician in the world.

You Bastard was thinking: there seems to be some growing dimensional instability here, swinging from zero to nearly forty— five degrees by the look of it. How interesting. I wonder what's causing it? Let V equal 3. Let Tau equal Chi/4. cudcudcud Let Kappa/y be an Evil-Smelling-Bugger20 differential tensor domain with four imaginary spin co-efficients…

Ptraci hit him across the head with her sandal. 'Come on, get a move on!' she yelled. You Bastard thought: Therefore H to the enabling power equals V/s. cudcudcud Thus in hypersyllogic notation . . .

Teppic looked behind him. The strange distortions in the landscape seemed to be settling down, and Dios was . . .

Dios was striding out of the palace, and had actually managed to find several guards whose fear of disobedience overcame the terror of the mysteriously distorted world.

You Bastard stood stoically chewing. . . cudcudcud which gives us an interesting shortening oscillation. What would be the period of this? Let period = x. cudcudcud Let t = time. Let initial period . . .

Ptraci bounced up and down on his neck and kicked hard with her heels, an action which would have caused any anthropoid male to howl and bang his head against the wall.

'It won't move! Can't you hit it?'

Teppic brought his hand down as hard as he could on You Bastard's hide, raising a cloud of dust and deadening every nerve in his fingers. It was like hitting a large sack full of coathangers.

'Come on,' he muttered.

Dios raised a hand.

'Halt, in the name of the king!' he shouted.

An arrow thudded into You Bastard's hump.

. . . equals 6.3 recurring. Reduce. That gives us ouch . . . 314 seconds . . .

You Bastard turned his long neck around. His great hairy eyebrows made accusing curves as his yellow eyes narrowed and took a fix on the high priest, and he put aside the interesting problem for a moment and dredged up the familiar ancient maths that his race had perfected long ago:

Let range equal forty-one feet. Let windspeed equal 2. Vector one-eight. cud Let glutinosity equal 7 .

Teppic drew a throwing knife.

Dios took a deep breath. He's going to order them to fire on us, Teppic thought. In my own name, in my own kingdom, I'm going to be shot.

Angle two-five, cud Fire.
