"They used their intelligence to control things around them, instead of letting nature and the strong-muscled have their way."

"Finally, in one fateful trillionth of a second, a nuclear compound was formed that had two very important properties: it was stable, and it could make a copy of itself. Life had come to the crust of the neutron star."

"An animal doesn’t need to develop curiosity and intelligence if it has no problems that need solving."

"After a short flurry of national and international concern over the “death of the Sun,” the human race settled down to solving the insoluble problem in the best way that they knew—they ignored it and hoped it would go away."

"If the computer had been a human, its eyebrows would have raised."

"They are signaling to us with the neutron star equivalent of America Indian smoke signals!"

"You are lucky. Very few theoretical scientists ever see their mathematical equations turned into working hardware in their lifetime."

"“Inertia propulsion!” Pierre exclaimed. “On our last shift we were teaching them Newton’s law of gravity. Today they have inertia drives! Where will they be tomorrow?” “They probably will be able to control space and time and won’t have to bother with such clumsy things as black hole gravity generators and inertia drives,” Amalita replied."
