Hmmmm. Last thing I saw, you claimed you put me in your "killfile." Glad
to see I'm off. (This makes me wonder why...) Hope I don't do anything
else to offend you. B^)

Hey, you're a sharp guy! Not too many people are aware of the Mossbauer
effect. I'll bet you read the same Scientific American article I did,
decades ago. Here's a question: How hard is
it to make a gamma detector? I'd like to experiment with the Mossbauer
effect, but aside from the difficulty of obtaining the radioactive nuclides,
I don't know to make a crystal detector. And is that the best an amateur

Yes, yes, yes, I know this stuff. But my pickiness was based on the fact
that the term "interact" can vary over many orders of magnitude. For
example, as I recall the ratio of the electrical repulsion between two
protons exceeds the gravitational attraction by a factor of about 10**40. I
just object to the use of the term "interact" in a cavalier way, as if
quantum mechanical "interaction" was the only kind of interaction that
"mattered." (no pun intended...well, maybe just a little.)

Okay, maybe not, but my idea is substantially better than anything I've
heard published in the open lay press. I just heard from a friend that even
that hack Clancy used krytrons and capacitors; my system would use _trivial_
components to do the timing.
