"I wrote many novels which … contained the element of the projected collective unconscious, which made them simply incomprehensible to anyone who read them, because they required the reader to accept my premise that each of us lives in a unique world."
- Philip K. Dick

| Photonic Sail | ||
| A sail that uses light pressure for propulsion. |
Unique name for a more common concept, all the rage in the early Sixties.
| "There will be time for the fun and games later. First, we have to get the work done. The photonic sails aren't picking up enough starlight to get us anywhere. The mainsail is ripped by a meteor. We can't repair it, not when it's twenty miles across. So we have to jury-rig the ship—that's the right old word."
"How does it work?" asked Veesey sadly, not much interested in her own question. The aches and pains of the long freeze were beginning to bedevil her. Talatashar said, "It's simple. The sails are coated. We were put into orbit by rockets. The pressure of light is bigger on one side than on the other. With some pressure on one side and virtually no pressure on the other, the ship has to go somewhere. Interstellar matter is very fine and does not give us enough drag to slow us down. The sails pull away from the brightest source of light at any time. For the first eighty years it was the sun. Then we began trying to get both the sun and some bright patches of light behind it. Now we have more light coming at us than we want, and we will be pulled away from destination if we do not point the blind side of the sails at the goal and the pushing sides at the next best source. |

Compare to the starlight sail from The Lady Who Sailed The Soul (1960) by Cordwainer Smith, the solar sail from Sail 25 (1962) by Jack Vance, which has a longer discussion of the topic. Don't miss the solar yacht from Arthur C. Clarke's 1963 short story Sunjammer.

'If the biological robots were not living creatures, they were certainly very good imitations.'
"Everybody and his dog, it seemed, wanted to live out in the country; transportation and communication were no longer isolating factors."
'... the new typewriter that could be talked to, and which transposed the spoken sound into typed words.'
'... underneath they consisted of networks of cooling tubes against the skin.'
