'Sure. Let's see. Once we decide to go ahead, I have to check the noise floor.' She looked up. 'That means I see if the target region is emitting a signal strong enough to be detected above the background noise. All electrical equipment generates electrical noise—electrons banging around in the metal of the equipment itself. We chill the receivers down in liquid helium to keep them really cold, because cold slows down the movement of the electrons and that reduces the noi—' The stare again. 'Right. You know that. Okay. If the target signal is really faint, we go around turning stuff off. Computers we aren't using for the shoot, lights, air conditioners, whatever. Then I choose a calibration signal—a known radio source. I shoot that to tune the system up.'
'How do you choose the calibration target? Briefly, please.'
'There's a huge catalog on-line and we pick one near the target signal. Usually I just look at the signal using a virtual oscilloscope. We know what a signal from a calibration source is supposed to look like.'
'And if the signal differs from expected?'
All business, Emilio said. Well, she has to eat…
'Mr. Quinn. If the signal differs from the expected?' she repeated, dark brows raised, stylus poised.
'That's where the art comes in. Each one of these dishes is essentially handmade. They all have quirks— cabling problems, grounding problems. The weather affects them, the time of day, the ambient noise. You have to get to know a piece of equipment like this. And then when you've eliminated everything, you have to use your intuition about what could be causing distortions or interference or stray signals. One time,' he said, warming up again, 'we thought we had an ET signal, extraterrestrial. We got it every few months but nobody else could confirm. Turned out it was the ignition of this one old school bus and we heard it every time the kids from that school came up here on a field trip.'
The Stare. It already had a capital letter in his mind. 'Listen,' he said seriously, 'I'm not just wasting your time telling funny stories. You have to know about stuff like this or your program is going to claim it's found intelligent life on Mars. And everyone knows there's only Australians there, right?'
She smiled, in spite of herself. 'Ah,' said Jimmy shrewdly. 'I see you've worked with Australians.'
For a moment, she struggled to return to sobriety but finally laughed. 'There's no such thing as beer too warm to drink,' she said with a very good Australian accent. Jimmy laughed then as well but, wisely, did not press his luck.
'How's it going?' George Edwards asked her, a month or so after she started. They met for lunch frequently, Sofia saving up questions to ask him on the days when he came to the dish.
'Slowly. Mr. Quinn is very cooperative,' Sofia conceded, looking up at George from the thick coffee mug she held in both small hands, 'but easily distracted.'
'By you,' George ventured, to see how she'd react, knowing that Jimmy was miserably besotted with a woman whose only interest seemed to be a relentless deconstruction of his brain, cell by cell. Sofia simply nodded. No blush, George noted, no compassion. She's not a romantic, that's for sure.
'It makes things difficult. Animosity is easier to deal with,' she said, glancing across the cafeteria at Peggy Soong. George grimaced: Peggy could be a pain in the ass. 'On the other hand, infatuation is preferable to condescension. I appreciate that you treat me as a competent professional, Mr. Edwards. It's nice to work without being patronized. Or chatted up.'
'Well, I hope this doesn't count as chatting you up,' George said dryly, 'but that dinner invitation is still open. What do you say?'
She had decided, upon reflection, to accept his invitation if he repeated it. People were often hostile to her work and, by extension, to her; she had not been invited to anyone's home since childhood. 'I'd be happy to come, Mr. Edwards.'
'Good. Anne's been wanting to meet you. Sunday afternoon? About two?'
'That will be fine. Thank you. I have some questions about weather effects on radio reception, if you wouldn't mind,' she said, setting her plate aside and pulling out her notebook. And they went on to business.
On Sunday, she drove to San Juan, allowing time for the dreadful traffic. She parked with difficulty, found a flower stall with ease, and bought a bouquet for Dr. Edwards. She liked Puerto Rico, actually, and had been pleasantly surprised to find how close Spanish and Ladino were. There were spelling differences, divergences in vocabulary, but the basic words and grammar were often identical. She asked the flower vendor the way to the Edwardses' address and climbed the stair-street to the shell-pink stucco house she was directed to. The doors to an ironwork balcony overlooking the street were open, as were the windows, and she clearly heard a woman's voice call, 'George? Did you get that pump fixed down in the clinic?'
'No, I forgot all about it.' She recognized Mr. Edwards's voice. 'Hell. I'll get to it. It's on the list.'
A peal of laughter rang out. 'So's world peace. I need the pump working tomorrow.'
Sofia knocked. Anne Edwards, white hair pulled into a messy bun, flour up to her elbows, answered the door. 'Oh, no!' she cried. 'Not just brilliant but good bones as well. I do hope you have a terrible personality, dear,' Anne Edwards declared. 'Otherwise, I shall lose faith in a just God.'
Sofia hardly knew how to respond, but George Edwards called from the kitchen, 'Don't let her fool you. She gave up believing in a just God when Cleveland blew the World Series last year. The only time she ever prays is the ninth inning.'
'And the night before a presidential election, for all the good it does. God is a Republican from Texas,' Anne asserted, bustling Sofia into the living room. 'Come into the kitchen and keep us company. Dinner's almost ready. The flowers are lovely, dear, and so are you.'
They passed through the living room, a pleasing jumble of books and watercolors and prints, with mismatched but comfortable-looking furniture and quite a good Turkish rug. Anne noticed Sofia take it all in and waved her floury hands at the place dispiritedly. 'We've only been here a year. I keep thinking I should do something about this place but there's never any time. Oh, well, maybe someday.'
'I rather like it as it is,' Sofia said honestly. 'It looks like someplace where you could fall asleep on the sofa.'
'Aren't you splendid!' Anne cried delightedly. Emilio often did exactly that. 'Oh, Sofia, that is so much nicer than thinking it's just a plain mess!'
They joined George in the kitchen. He directed Sofia to what Anne called the Kibitzer's Stool and handed her a glass of wine, which she sipped as George finished slicing vegetables for the salad and Anne went back to whatever it was that involved flour. 'George does all the knife work,' Anne explained. 'I can't afford to get cut. Too much risk of infection. I dress like an astronaut when I'm in the ER or the clinic but it's better to keep my hands out of harm's way. Do these cookies look familiar?'
'Why, yes. My mother used to make those,' Sofia said, a little startled by the memory of meringue-topped sweets.
'Ah, lucky guess,' Anne murmured. The menu had been easy and Anne had enjoyed putting it together. Sephardic cuisine was basically Mediterranean—light, sophisticated, emphasizing vegetables and spices. She'd found a recipe for
They took Turkish coffees into the living room after dinner, and the conversation turned to music. It was George who noticed Sofia looking at the old piano against the wall. 'It doesn't get a lot of use,' he told her. 'The last tenant left it in the house. We were going to give it away but then we found out that Jimmy Quinn can play, so we had the thing tuned last week.'
'Sofia, do you play?' Anne asked. It was a simple question. The girl's hesitation was surprising.
'My mother was a music teacher so, of course, I had lessons when I was little,' Sofia said finally. 'I can't remember when I sat at a piano last.' But she could remember. The time of day and the way the sunlight slanted through the window in the music room and her mother nodding and commenting and sitting down to demonstrate a different phrasing; the cat jumping onto the keyboard only to be dumped unceremoniously onto the carpet, the practice session punctuated by occasional gunfire and the thud of a mortar shell landing somewhere nearby. She could remember everything, if she let herself. 'I'm terribly out of practice.'
'Well, give it a try,' George said.
