Re: Wave phase reversal on reflection

[Jack Uretsky <jlu@HEP.ANL.GOV>]

Remove the boundary.  The reflected wave projected past the boundary
must exactly cancel the incident wave in the region beyond the boundary.

Adam was by constitution and proclivity a scientist; I was the same, and
we loved to call ourselves by that great name...Our first memorable
scientific discovery was the law that water and like fluids run downhill,
not up.
