Let's be thankful they didn't. (Basically because they refused to work
on it because it was "Jewish physics") Had they not been so
ethnically shortsighted they'd have won the war and we'd all be
speaking (singing) German now. :(
===========================================
What's wrong with that?
Freude, schoner Gotterfunken,
Tochter aus Elysium,
Wir betreten feuertrunken,
Himmlische, dein Heiligtum.
Deine Zauber binden wieder,
Was die Mode streng geteilt,
Alle Menschen werden Bruder,
Wo dein sanfter Flugel weilt.
Seid umschlungen, Millionen!
Diesen KuB der ganzen Welt!
Bruder - uberm Sternenzelt
MuB ein lieber Vater wohnen.
===========================================
Speaking of CDs I worked on a device that was a thin film disk written
on by a laser back in the early 70s with some schoolmates of mine who
had a patent on it. The patent was assigned to another company who
retained the rights for data storage for point of sale use. My friends
had all other rights. [basic idea was the disk would record all bad
credit card numbers transmitted by radio overnight.They later went to
just calling in by phone instead.] My pals kept trying to figure out
what such a storage device would be good for if it wasn't for credit
card numbers? They couldn't think of a thing! I just smiled and said
nothing figuring if they couldn't figure it out, I sure as hell was
not going to make them rich. Eventually others did a slightly
different variation on the same idea for audio recording. Those
clowns suffered from the same syndrome in that they couldn't think of
using it for computer data storage either. Oh well, the smartest man
in the universe [Bill Gates] couldn't figure out the internet might be
useful either.
==============================================
I've got a problem like that. If I patent my light accelerator now
I can see an immediate use for it when someone gets around to
going to Mars, but by the time that happens someone will have
read my patent, realised its potential, thought of a better way and
I'll end up with nothing. It's kinda like Edison's cylindrical phonograph,
it worked in principle but was soon superseded by the disc with a
spiral groove in place of a helical one, and now that's replaced
by the memory stick with no moving parts at all. So I need an
immediate use for it now and I can't think of one. Concorde
was the fastest airliner ever, but the economics of jumbo jets
meant it was before its time, as my light accelerator is. |

For a few dollars I can buy a diffraction grating that's much much

And for a few dollars I can buy a laser that's much much better than the
one Michelson used.
And for a few dollars more I can buy a sheet of polaroid that's far
better than the one Fresnel used.
It ought to be pretty cheap and easy to replicate the old experiments,
given modern technology. I got excited. I looked around the house. We
had one place that would be perfect, a pretty long distance, half of it
a narrow corridor, I could open the bedroom door to get more distance if
needed, a mirror already mounted at the far end. Perfect! Particularly
at night. Maybe I could show the results to my kids, they might be
interested.
So I went to my wife and asked her. "Honey, I was thinking I'd like to
do some laser experiments, and the hall would be just perfect for it,
would you mind if I set up some stuff there?"
She laughed. "That's perfect! I like it! My husband wants to set up a
laser lab in our hall. I'm going to dine out on that story for months."
"OK, so you don't mind?"
"Are you serious?! Hell no! Lasers around my kids? I like to joke about
you being a mad scientist making death rays but no."
"You don't mind the kids teasing the cat with lasers."
"That's different."
Maybe it isn't so easy after all.

That's why Newton never married. :-)
But to be serious:
You can indeed quite easily and cheaply repeat many
of the classic experiments. But only as a demonstration
of the principle, to make a serious optical experiment isn't
much simpler now than it was 'in the old days'.
Take the MMX as an example. It's quite easy to make a Michelson
interferometer, but the fringes will likely drift even if you do not
rotate it. Michelson's problem was not the lack of a laser
(he had narrow-band source, Na - lamp), it was to get the whole
set-up stable enough. That's why he ended up with the interferometer
mounted on a slab of stone floating in mercury.

I expect that some things are easy and some are hard. It's the hard ones
that require serious experimental physicists, and there will be a place
for them no matter how easy some traditional projects get.

Sure. I wouldn't try to do that one. On the other hand, I can imagine
doing something like that looking for the confounding variables.
Something like MMX might turn out to be a sensitive vibration detector,
etc. The trick is to find a way to cheaply control for all but *one*
confounding variable at a time.... |

So, Aut, your position is that the Germans did NOT refuse to work on
the CD during WWII based on the premise that it was "Jewish
physics"? Interesting. I'd love to see some examples of these war-
time discs! On the other hand I HAVE seen the German magnetic tape
recorders that was the making of the Ampex corp which they
manufactured as virtually exact copies without license or royalties
after the war.

Great Story, Bill!
Say, you didn't happen to run into the Fuhrer himself roaming around
down there did you? I heard rumors that He and his family were living
back in the weeds somewhere... He probably would be hard to spot
without that silly mustache.
[reminds me of the Monty Python sketch of a "Mr. Hilter" living in a
rooming house in London...] |

As long as we are on memory lane, years ago in Bogota, Colombia, I knew a
former German officer that was Hitler's personal tape recorder engineer. The
tape recorder was designed to protect Hitler from being bombed to
smithereens.
Hitler's problem was that whenever he got on the air with a speech, Allied
RDF would triangulate on the transmitter and fast bombers were sent in to
bomb it. Since his speeches were often quite lengthy, the Allies had plenty
of time to get to most German sites. Apparently Hitler had several
near-misses.
The Germans tried disk transcription and wire recorders, but neither had
enough fidelity to "fool" the Allies. But magnetic tape was
indistinguishable from "live," thus preserving the Fuehrer's life for the
glory of the Third Reich.
This was one of two encounters I had in South America with ODESSA.

Why Aut thinks the Eurovision Song Contest is a myth we'll never know.[/quote]
Top choice was the popular duet, "Deutschland, Duetschland Uber

Poland, Czechoslovakia... Terry Wogan hosted it.
