I woke up with a sudden thought.

For a few dollars I can buy a diffraction grating that's much much
better than the one Newton used.

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.

On the other hand, if I'd gotten that kind of response from my wife,
the next conversation would have been:
"What are you doing?"
"I'm setting up an experiment in the hall. I've let the kids know to
stay away."
"You're doing WHAT?"
"Trying an experiment. Do you want to help or watch?"

So get a better wife or do without one. Hookers are far cheaper.
Problem solved. <shrug>

I have a laser light source, a set of mirrors at the corners of a rectangle,
and
a phototransistor all hanging about 9" below my living room ceiling.
It works like this:
http://www.androcles01.pwp.blueyonder.co.uk/lightclock.gif
It used to have a set of frequency dividers for a clock display, but I
got bored, didn't finish it and now it is collecting cobwebs.

PS... shh...don't tell Humpty Roberts.

Do some experiments and have some fun. You are exactly correct that
the tools we have to work with now are so much nicer than those
the pioneers had in their areas. Some tthings do not change much
though, like the requirement for temperature stability in
the MMX experiment. That is where the money is today in duplicating
that experiment. Of course, you could always do it badly and get
results like Cahill and the others he likes to quote.

I do not think this post is serious, but I saw no smilies. Nevertheless
the feats of procurement described merely apply 20th century progress to
earlier ones.

That's a minor detail. You know lasers have gotten a lot better and

Michelson died in 1934, the laser wasn't invented until 1958. It was
preceeded
by the maser. The first working laser was demonstrated on 16 May 1960 by
Theodore Maiman at Hughes Research Laboratories.

Your minor detail is a non-existent detail.

gratings. Do you know how much Newton had to pay for his crappy
diffraction grating?

I read that Newton told somebody -- I think it was his cleaning lady --
how much he paid for a prism, and she laughed at him. He asked her how
much she thought it was worth and she said he should have paid according
to the weight of the glass, of course.

Sure, not to mention Newton's diffraction grating and Fresnel's
polaroid.

Fresnel could have had a diffraction grating, though. If he didn't want
to settle for a bird feather or something like that, he could have asked
Fraunhofer for one.

How expensive do you imagine a laser was in Michelson's day?

Come on. That's just gummint claptrap. Everybody knows the Germans
invented lasers in secret and Michelson had one of those. The laser
technology was taken by the U.S. after WWII and then finally released
as if it was a new idea in 1958 along with ICBMs, UFOs, fiber optics,
transistors and all the other Nazi inventions that were gathered up in
project LUSTY and related projects. When it comes to real conspiracies
you guys are just babes in the woods.

===============================================
The Nazi party's last leader, Adolf Hitler, was appointed Chancellor of
Germany
by president Paul von Hindenburg in 1933.
Just one year for it to be a Nazi invention and given away to
the USA for Michelson's birthday prezzie before the old chap
croaked. The thing is, why didn't the Nazis invent the compact disc
to go along with it, flood the market with cheap records and win
the Eurovision Song Contest?

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. :(

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.
