"Generally, the human race avoids doing anything radical until forced into it."
- Frederik Pohl

Selenium Photo-Electric Televisor  
  A specialized photo-electric cell.  

Then a bell sounded.

"That is the signal that we have passed the limit of gravity between the earth and the moon..."

In fact, without that signal which was given by an ingenious selenium photo-electric televisor, as soon as the disk of the moon enlarged beyond a certain size on the projection surface, which corresponded to the previously calculated distance of the point free from gravitation, they would not have noticed at all that the ship had now passed from the sphere of influence of the earth into that of its satellite.
