1. It would be interesting to know what human characteristics lead
to reproductive success these days in both primitive and advanced
societies.

2. Can we make a uranium getter that could be thrown in the sea,
would combine with dissolved uranium ions, and would rise to the
surface?  The laws of diffusion seem to say that the getter molecules
would collide with available uranium ions quickly enough, but it is
more problematical how to get the combination to come to the surface.
Perhaps we could make a plankton that likes the getter and a whale
that likes the plankton.

3. Is it reasonable to predict the effect of an increase in average
income by supposing that people would behave like the present
behavior of the income group they move into?
