There's an old speculation about what would happen if we finally built a computer with as many transistors as the human brain has neurons.

First of all, the whales' songs: these old speculations which our hero has now confirmed.

Like the old speculation that maybe galaxies were really neutrons or mesons inside a far vaster universe, or the old question, If the universe isn't infinite, what is beyond the edge?

Just more speculation about Napoleon's whereabouts and troop movements, all four or five days old.

I even dredged up some old speculations as to his part in your own passing, Corwin.

The rover's combination of microscope and camera, along with the German-built spectrometers, may answer the old speculation about "canals": do the rocks show the previous presence of water, which could have supported life?

That is more reason like than the 200 year old speculation about 'reason'.

But it is useless in me troubling you with my old speculations.

It was like the old speculations--what would happen if an elephant could leap up in the sky like a grasshopper?
