“Yes. For twenty-three years.”
“Well, then…but, why — ”
“We can’t,” Mordan said flatly, with just a shade less than his usual calm. “She’s a mutation…sterile.”
Hamilton’s ears still burned to think that his big mouth had maneuvered his friend into making such a naked disclosure. He had never guessed the relationship; Martha never called Claude anything but “chief”; they used no words of endearment, nor let it creep otherwise into their manner. Still, it explained a lot of things-the rapport-like co-operation between the technician and the synthesist, the fact that Mordan had shifted to genetics after starting a brilliant career in social administration, his intense and fatherly interest in his charges.
He realized with a slight shock that Claude and Martha were as much parents of Theobald as were Phyllis and himself-foster parents, godparents. Mediator parents might be the right term. They were mediator parents to hundreds of thousands, he didn’t know how many.
But this wasn’t getting his work done-and he would have to go home early today, because of Theobald. He turned to his desk. A memorandum caught his eye-from himself to himself. Hmmm…he would have to get after that. Better talk to Carruthers. He swung around toward the phone.
“Chief?”
“Yes, Felix.”
“I was talking with Doctor Thorgsen the other day, and I got an idea-may not be much in it.”
“Give.” Way out on far Pluto, the weather is cold. The temperature rarely rises above eighteen degrees centigrade absolute even on the side toward the sun. And that refers to high noon in the open sunlight. Much of the machinery of the observatories is exposed to this intense cold. Machinery that will work on Terra will not work on Pluto, and vice versa. The laws of physics seem to be invariable but the characteristics of materials change with changes in temperature — consider ice and water, a mild example.
Lubricating oil is a dry powder at such temperatures. Steel isn’t steel. The exploring scientists had to devise new technologies before Pluto could be conquered.
Not only for mobiles but for stabiles as well-such as electrical equipment. Electrical equipment depends on, among other factors, the resistance characteristics of conductors; extreme cold greatly lowers the electrical resistance of metals. At thirteen degrees centigrade absolute lead becomes a superconductor with no resistance whatsoever. An electric current induced in such lead seems to go on forever, without damping.
There are many other such peculiarities. Hamilton did not go into them-it was a sure thing that a brilliant synthesist such as his chief had all the gross facts about such matters. The main fact was this: Pluto was a natural laboratory for low temperature research, not only for the benefit of the observatories but for every other purpose.
One of the classic difficulties of science has to do with the fact that a research man can always think of things he wants to measure before instruments for the purpose have been devised. Genetics remained practically at a standstill for a century before ultramicroscopy reached the point where genes could really be seen. But the peculiar qualities of superconductors and near superconductors gave physicists an opportunity, using such chilled metals in new instruments, to build gadgets which would detect phenomena more subtle than ever before detected.
Thorgsen and his colleagues had stellar bolometers so accurate and so sensitive as to make the readings of earlier instruments look like a casual horseback guess. He claimed to be able to measure the heat from a flushed cheek at ten parsecs. The colony on Pluto even had an electromagnetic radiation receiver which would-sometimes-enable them to receive messages from Terra, if the Great Egg smiled and everyone kept their fingers crossed.
But telepathy, if it was anything physical at all-whatever “physical” may mean! — should be detectable by some sort of a gadget. That the gadget would need to be extremely sensitive seemed a foregone conclusion; therefore, Pluto seemed a likely place to develop one.
There was even some hope to go on. An instrument-Hamilton did not remember what it had been-had been perfected there, had worked satisfactorily, and then had performed very erratically indeed-when the two who had perfected it attempted to demonstrate it in the presence of a crowd of colleagues. It seemed sensitive to living people.
