How about that.

You know I bought an electronic watch some months ago maybe 2 years I don't know it didn't cost much

And some of those watches have around scale or display that is

Some of them have a tidy squared display


And they connect with a little USB connector having four pins and a magnet-oriented correctly


Well on the used market.....


The aging watches which are not compatible with modern watch operating
systems and routines are probably pretty available at low cost

And separately

I already donate to the only open source watch software group I know of

The business opportunity is clear I don't know if I'll pursue it but it's
clear so I'll articulated it here and then go on a little bit about the technology


All that a person has to do to start this conjugate variable meter
revolution without getting down into the OEM level is get a bunch of old watches takes the straps off connect the USBs boot the open source
operating system and write an app in that system that converts the watch
into a conjugate variable double needle display!

Now even a two needle voltmeter showing a V1 compared to a V2 on the same
scale as running like $300 will manufactured in America

The double cross needle things are almost always used for radiated power
and reflected power in evaluation of these ratio between them the SWR
meter? And those are bloody expensive as well.


Now the physics:

Conjugate variables like pressure and volume and like voltage and current
are probably pretty well known to you so I'll move on

Conjugate variables like momentum and position and like pressure and volume
at least I think about the case of pressure and volume I'm sure about the
case of momentum and position are indeed what they call canonically
conjugate variables subject to the standard Heisenberg uncertainty relation

And the way I read that is the theme multiplication of such variables is non-commutative pardon theme is transcription there

For example if momentum is p and position is d

pd - dp > function of hbar only


You see I didn't do very good at quantum so I'll stop there

I'll hypothesize that a routine for a watch having an accelerometer in it
would be interesting

Interesting to physics folks anywho....

You see the integration of acceleration provides position if you integrate twice, and the integration of acceleration provides momentum, since you
know the mass of the watch, if you integrate once.

So if a physics minded person might enjoy a watch where the hands could be second minute an hour hands in the conventional sense but could also be switched to two intersecting hands based in the corners of a square display showing the position and the momentum of the watch instant by instant and showing where the needles intersect what the expected uncertainty would be

I'm just tickling your brain I'm not suggesting that anyone go off and
start a business doing this

Just tickling your brain and hoping to learn a little bit more about
quantum. Perhaps one of you will comment.

Now certainly I will go check out ebay for the old watches which are incompatible and visit my site where I donated dollar a month I mean it
isn't much but there is an open source software that completely replaces
all the inbuilt software in a watch

I'll do that and report here.



Other than that,
[[Mod. note --

1. I'm sorry, I mistakenly deleted the author's last line, which was
something like "Deep in the replikon net".

2. Are pressure and volume conjugate variables in the quantum-mechanics
sense? Voltage and current?

3. If the watch is attached to a (living) human, I'd expect its movements
to be sufficiently large that quantum effects would be negligible.

4. Finally, I don't think real accelerometers -- certainly ones small and
light and low-power enough to fit into a watch -- are accurate enough
to detect quantum effects in motion. See
https://www.navigationsolutions.eu/wp-content/uploads/2017/05/Ellipse_Series_Leaflet.pdf
to get a sense of what current commercial "small" inertial measurement
systems look like. These combine accelerometers, magnetometers (to sense
orientation), micromechanical gyroscopes, and GPS receivers. The brochure
says the smallest unit in this product family weighs 45 grams, requires
about 1/2 watt of power, and is about 34 x 34 x 13 millimeters in size.
