Push-pull
Index Entry
In reviewing with EJA Athena V. Lord's manuscript of PILOT FOR SPACESHIP EARTH, RBF came across a description of conventional stone structures held together by compression ..."where the top stones are pushing down on the ones beneath."
RBF: "Nothing could be more redacted erroneous. How could a top stone push? What would it have to push against? . . . . What happens is that gravity pulls the top stone--and all the others--against each other."
