Hi --

Here's another riddle that you may find entertaining and/or
pedagogically
useful.

Short version: At the most basic physics level, what makes a turbojet
engine
go the right way? If somebody asks you how a turbojet works, can you
give
an answer that gets the basic physics right?
. . .
Bonus question / corollary: What does your answer imply about various
good
and/or bad ways of *starting* a turbojet engine?
