That would have allowed him a clearer shot; and there would be no signature of noncongruent energies.

That was exactly what he must not do, of course; far too much noncongruent energy release to be safe, with the Domination's scientists searching the continua.

The physics . . . he's afraid that use of noncongruent energies will somehow make it easier for the Technical Directorate to home in on us here.

According to which three edge arcs are replaced (three that have a common vertex or three that form a triangle) there result two noncongruent shapes that are sometimes called Meissner bodies or Meissner tetrahedra (for interactive pictures and films see Weber).
