250A portable test set, 850 amps into copper braid

[George Herold]

Oh, cripes. They are ALL my favorites, since I haven't
actually built any of them, yet.

But I'm particularly interested in playing around with the
experiments requiring a vacuum pump. Actually making my own
evacuated systems is a lot different that using "store
bought" products that are already done and sealed and only
usable for one or two experiments. This would develop and
refine new skills I don't currently have and teach me a lot
about practical problems along the way that I'd like to
learn. It would open doors to new things for me and I like
that. I'm more interested in this that the next one below
because it's more achievable for me, I think.

Obviously, I'd like to test Bell's inequality myself. That's
later in the book. I'm not sufficiently convinced that his
design is up to the real challenges, though. I think there
are sources of error that are too large and that he "got
lucky" in finding approximately the right values that he
reported. So I really think that when I get more into it, it
will wind up costing more than I really imagine in getting
the right parts. And that trying to avoid that cost and
building them myself won't make it any better. I just don't
have the right infrastructure here and getting enough of it
will set me back too much money. So before I dig into that
area, I have MORE reading to do and hopefully more study
about the details so that perhaps I can either convince
myself his approach is good enough or that I can come up with
something else that takes really good ideas from several
sources.

Another book I'm finding some recent joy with is:

Ahh I've heard of that book. I think I have way to many QM books,
back when I was trying to learn it, I over compensated and bought
more books rather than studying one in depth. (I didn't have a good
QM teacher.)

I think it takes an approach that is enough different to be
worth a short look, George. Check out a copy and see what you
think. I'm pretty much in the same boat as you, I suspect.
But this one is reaching me better than others have. Try out
the first chapter or two.

It would, of course, be better still with a good teacher to
talk with. But they are harder to come by than a book.

Ahh, thanks, I think. (Was that supposed to help?)

Hi Jon, I think my favorite text is the one by J.J. Sakuria.
http://www.amazon.com/Modern-Quantum-Mechanics-Revised-Edition/dp/0201539292
The only way I can learn this stuff is by doing the problems.
(This was in the deep past when I needed to pass the PhD qualifing
exam.)

Thanks, George. I'll look that one up.

I remember from those old days the HV transformers filled with that poisonous PCB oil,
and I remember seeing them dumping it in the river...
http://en.wikipedia.org/wiki/Polychlorinated_biphenyl

And I am still alive!

Yeah, but for how much longer? Uh, that's not a threat!

BTW, where are you? I'm in MD, are you still there? I never heard of
Sparks, but Accident is near Deep Creek Lake I believe.

PCBs are a major source of continuing pollution across our country. At
Lake Anna PCBs are present to the extent they recommend you don't eat
too much of the fish caught here. I knew that of the Potomac and the
James rivers, both large rivers with large watersheds. But I never
expected to have that at a lake not at all far from head waters. I'm
told it is not point source pollution, but just lots of oil, etc poured
on the ground over many, many years. It will be here through my
lifetime. Any yet, when it comes to preventing other forms of pollution
people just don't want to believe we have problems. It won't be too
many generations before the earth truly isn't fit to inhabit and we have
to live indoors.

I'm not Jan, but I'm in Cockeysville on the edge of the Loch Raven
Watershed. And Sparks is a tiny whistle stop along York Road and is also
referred to as Loveton, after a mansion that was there.
http://en.wikipedia.org/wiki/Sparks,_Maryland

And this is the building that was headquarters of EIL Instruments while I
worked there from about 1980 to 1989:

And, yes, Accident is near Deep Creek Lake, and is/was also home to an
ambulance dealer or manufacturing company:

I'm quite familiar with Lake Anna and I have done some work at the nuclear
plant. It is (or at least was) one of the most open and accessible plants I
have visited, compared to TMI and the Brunswick plant on Cape Fear:
http://www.nucleartourist.com/us/brunswick.htm
That was my first visit to a nuclear facility (except for a tour of Peach
Bottom when I was still a kid), and I was impressed by the sight of a drop
dead gorgeous Southern Belle toting an M-16. I remember when PCBs (Askarel)
were hailed as a breakthrough in the electrical trade because it did not
deteriorate as transformer oil and was considered non-toxic.
http://en.wikipedia.org/wiki/Transformer_oil

I think people will always be deluded by big business to minimize their
concern for environmental issues and maximize their corporate profits. What
I find most disturbing is that so many engineers, technicians, and science
types are also right-wing fanatics who are AGW deniers and promoters of
off-shore drilling, fracking, mountaintop removal, and other environmentally
dangerous practices.

yeh you'd think the history of for example, lead paint, lead in
gasoline, asbestos, ddt, CFCs, Roundup etc.
would have taught the world a lesson

PCB also has the distinction of being a bioaccumulative carcinogen.
