I don't see Art's postings except as they're quoted by others. But from
what I'm seeing here, it looks like he's done a great experiment which
graphically shows that radio waves don't act like particles. More
experiments along this line weren't really necessary, since it's been
known at least since Hertz's experiments in the 19th century. And anyone
who took high school physics and watched the ripples in the ripple tank
should be able to immediately predict what Art is describing. But I
suppose the experiment and its results might prove enlightening for
those readers who didn't take high school physics and who are nearly
completely unacquainted with electromagnetics.
