He nodded. Her programmed night out, full of forced gaiety, had begun to wear on him. And the sudden shifts in his emotions bothered him as well. He normally thought of himself as rock-steady, unmoved by passing notions.
“Got a call from Saul today,” he said stonily, fleeing his own thoughts. “He and Frank Drake are going to get time on the big radio telescope in Green Bank, West Virginia. They want to study 99 Hercules.”
“If they receive a signal, it will prove your case?”
“Right. It makes no sense, but—right.”
“Why no sense?”
“Look, I mean—” Gordon waved a hand in exasperation. One of the waiters took this as a signal and began to advance. Hurriedly Gordon motioned him away. “Even if you bought the story whole, the tachyons and everything —why think there should be radio signals? Why
“Well, at least they’re doing something.”
“Were you a cheerleader in high school, too?”
“God, you’re a nasty bastard sometimes.”
“Wrong time of the month.”
“Look, Saul is trying to help.”
“I don’t think that’s the way to solve the problem.”
“What
“Forget it. That’s the best way. Just hope everybody else will forget it, too.”
“You don’t really—”
“Sure I do. You should’ve been at that Colloquium.”
She let him cool for a moment and then murmured, “You were confident a week ago.”
“That was a week ago.”
“At least you could work on it.”
“Cooper’s candidacy exam is two days away. I’m going to concentrate on helping him prepare, and then on getting him out. That’s my
“Maybe you should try something like what Saul’s doing.”
“No point.”
“How can you be so sure?” She folded her arms, sitting back in the rattan chair and looking squarely at him. “Have you ever thought about the rigid way scientists work? It’s like military training.”
“Bullshit.”
“What do they teach you? Write down everything you know about a problem. Set it up in some equations. Most of the time, that’s enough in itself, right? You just push the equations around a little and you’ve got the answer.”
“Not that simple,” Gordon said, shaking his head. But to himself he had to grudgingly admit that there was some truth to what she said. Assign symbols, making the
“Let’s have chocolate mousse,” Penny said brightly.
He looked up at her. She was going to make this evening end right, one way or the other. He remembered her perched on the toilet and felt a warmth steal over him. She had been both vulnerable and serene sitting there, performing an animal function amid a gauzy gown. Pert, and oddly elegant.
“Vas you-are dinner ex-see-lant, sir?”
Gordon peered at the waiter, trying to estimate if he was queer. “Ah… yes. Yes.” He paused. “Lots better than Chef Boy-Ar-Dee.”
The expression on the waiter’s face was worth the price of the meal.
CHAPTER TWENTY
ALBERT COOPER’S CANDIDACY EXAMINATION BEgan well enough. Gates, a high-energy physicist, started off with a standard problem. “Mr. Cooper, consider two electrons in a one-dimensional box. Can you write down for us the wave function for this state?” Gates smiled in a friendly way, trying to defuse the tension that oral examinations always had. The student nearly always balked somewhere along the line, unable to summon up some simple piece of physics purely because of his own skittering nervousness.
Cooper worked his way through an opening piece of the problem, sketching the lowest energy state. Then he stalled. Gordon could not tell if this was simple funk or a calculated delaying tactic. Lately, students had hit upon the frowning, silent stall as a method for extracting hints from their committee. Often it worked. After a moment Gates said, “Well then… should the spatial part of the wave function be symmetric?” Cooper responded eventually, “Ah… no… I don’t think so. The spins should be…” and then, halting now and then, he successfully got through the rest.
Gordon felt uneasy as Gates led Cooper through a series of routine questions, all designed to find out if the candidate knew the general background of the thesis problem he proposed to attack. The air conditioning hummed with vacant energy; Cooper’s chalk scratched and squeaked on the board. Gordon eyed Bernard Carroway, the astrophysicist. No trouble there. Carroway looked bored, impatient to be done with this ritual and get back to his calculations. The fourth and last member of the committee was the only problem: Isaac Lakin. As senior professor in the field of Cooper’s thesis, his presence was unavoidable.
Gates finished his simple questions and Carroway, blinking sleepily, passed to Lakin.
But Lakin was not so direct. He took Cooper through a discussion of Cooper’s own experiment—usually safe ground for the student, since that was what he knew best. Lakin stressed the theoretical underpinning for the nuclear resonance effects. Cooper wrote down the scaling equations, working quickly. When Lakin probed deeper, Cooper slowed, then stopped. He tried the stalling tactic. Lakin saw through this and refused to give Cooper any meaningful hints. Carroway began to take an interest, sitting up straight for the first time during the examination. Gordon wondered why a student in difficulty always provoked more attention from a committee; was it the hunting instinct? Or a proper professorial concern that the student, presumed to be accomplished until he proved otherwise, had suddenly betrayed a fatal ignorance? Either answer was too simple, Gordon concluded.
By now Lakin had Cooper on the run. Lakin made him frame a clear picture of the theoretical model and describe the underlying assumptions. Then Lakin cut Cooper’s explanation to ribbons. His statements were vague, his reasoning sloppy. He had neglected two important effects. Gordon sat absolutely still, not wanting to interrupt because he still clung to the hope that Cooper would right himself after being blown over in this quick storm, and begin to answer correctly. That hope faded. Gordon remembered Lakin relating a comment he had written on a thesis some years ago: “Young man, there is much in this work which is original and much which is correct. Unfortunately, what is correct is not original, and what is original is not correct.”
Carroway joined in with a few incisive questions. Cooper seemed to make headway, then reverted back to his withdrawal mode, stalling for time. But in a two-hour examination there is more than enough time to uncover weaknesses. Carroway listened to Cooper’s floundering replies, eyes still half-closed, but now obviously alert, a sour expression spreading across his face. Gates peered at Cooper as if to understand how a student who had appeared bright only moments before could now be in such trouble. When Cooper turned to answer a sally from Lakin, Gates shook his head.
Gordon decided to step in. It was not a good idea to defend your student very much in the candidacy examination precisely because it was so obvious, and it implied that you, too, conceded the student’s defects.
