The man smiled: “Wha’s that again?”

They understood! He repeated the formula, slowly, and would have explained further, but the man cut him off.

“Math,” the man smiled. “We don’ use that stuff no more. I got a lab assistant, maybe he uses it sometimes.”

They were beyond mathematics! They had broken through into some mode of symbolic reasoning that must be as far beyond mathematics as math was beyond primitive languages!

“Sir,” he said eagerly, “you must be a scientist. May I ask you to——”

“Get in,” he smiled. Gigantic doors unfolded from the vehicle. Thought-reading? Had the problem been snatched from his brain even before he stated it? Mutely he gestured at Helena and Bernie. Jones would be all right where he was for several hours if Ross was any judge of blackouts. And you don’t quibble with demigods.

The man, the scientist, did something to a glittering control panel that was, literally, more complex than the Wesley board back on the starship. Noise filled the vehicle—noise that Ross identified as music for a moment. It was a starkly simple music whose skeleton was three thumps and a crash, three thumps and a crash. Then followed an antiphonal chant—a clear tenor demanding in a monotone: “Is this your car?” and a tremendous chorally-shouted: “NO!”

Too deep for him, Ross thought forlornly as the car swerved around and sped off. His eyes wandered over the control board and fixed on the largest of its dials, where a needle crawled around from a large forty to a large fifty and a red sixty, proportional to the velocity of the vehicle. Unable to concentrate because of the puzzling music, unable to converse, he wondered what the units of time and space were that gave readings of fifty and sixty for their very low rate of speed—hardly more than a brisk walk, when you noticed the slow passage of objects outside. But there seemed to be a whistle of wind that suggested high speed—perhaps an effect peculiar to the cooling-fin power system, however it worked. He tried to shout a question at the driver, but it didn’t get through. The driver smiled, patted his arm and returned to his driving.

They nosed past a building—cooling fins—and Ross almost screamed when he saw what was on the other side: a curve of highway jammed solid with vehicles that were traveling at blinding speed. And the driver wasn’t stopping.

Ross closed his eyes and jammed his feet against the floorboards waiting for the crash which, somehow, didn’t come. When he opened his eyes they were in the traffic and the needle on the speedometer quivered at 275. He blew a great breath and thought admiringly: reflexes to match their superb intellects, of course. There couldn’t have been a crash.
