"The immediate problem with our meat brains is that they have no back-up. We can lose the most precious information we have from one bump on the head or stroke. You want a mind system with back-up that can access other databases."
- Bart Kosko

| Curtain (Force Barrier) | ||
| An easily set-up protective force barrier. |
Interesting early use of the "force field" idea; note that the authors felt that the barrier needed wires to carry energy.
| The dripping jungle pressed its greyness close up against the interlacing net of copper filaments that was the Curtain, the apparently frail barrier around the liquid mud clearing of this outpost of Earth's commerce…
At last they were through the Curtain. Arnim turned, took something from the voluminous pocket of his waterproof. A tiny radio-transmitter, low-powered, sending only a long dash that varied completely in wave length for a half minute. The key to the Curtain—Penger pressed the button. A coruscation of tiny flashes snapped through the wind-tossed filaments. The power was on—that apparently frail barrier hummed now with the Grendon vibration. Britt could see the driven rain rebound from the invisible wall. Nothing, no human body, no Venusian dart, not even a high-powered electro-bullet could pass through the net. The station was safe, protected against all intrusion until the machines that produced the vibration were stilled by another pressure on the little instrument with its secret combination of frequencies. |

Compare with the force-field from John Campbell's 1931 story Islands of Space, the barrier from Robert Heinlein's 1940 novella Coventry and the Langston field from Niven and Pournelle's 1974 classic The Mote in God's Eye.

'the unobtrusive inspections with tiny remote-cast snoopers...'
I'm hoping that this procedure becomes a normal part of medical practice!
'... nothing was perfected until M. Pantalon announced the completion of his automatic valet.'
'...its streets were of remarkable width, with few or no buildings so high as mosques, churches, State-offices, or palaces in Tellurian cities.'
'...it was all composed of tiny, identical cubes, carefully laid to form a tilelike surface.'
