Oh, care to explain, or, perhaps your new posting style is just "cut and get cut".
Stern-Gerlach basically demonstrates that it must be continuum mechanics that it must be quantum mechanics not simply particle mechanics.
Not that it demonstrates "particle mechanics", which is a usual thing that people think since "quantum mechanics" is said to be what is "particle mechanics".
Must be waves, ..., in fields.
Geometry is motion.
Truth is regular, ..., geometry is motion.

No, it demonstrated that quantum-mechanical systems ("particles") have a property called "(quantum-mechanical) spin", an intrinsic form of angular momentum that is quantized. In particular, the experiment showed that (silver) atoms have this property, and that the projection of their spin can only assume one of two possible values (which for both physical and mathematical reasons were chosen to be +ℏ/2 and -ℏ/2; physics justifies the ℏ) which makes them behave like that in a magnetic field:

That "nothing but" ignores the fact that the output of the cesium clock has a much more stable frequency than the outputs of regular quartz clocks. That's why people pay more money for them.

The process of turning a frequency standard into a clock is fairly complicated but the devices are already sold as clocks.
The next generation of references will presumably depend on an oscillation of the atomic nucleus rather than of the electrons orbiting around it. Thorium-229 has a very low energy nuclear resonance and there are proposals to exploit it.

But if it's parents had been growing crops on an area that got submerged, the baby might not have had the energy to crawl far enough or fast enough.
Which aren't particularly rich in food resources.
It happened in the obvious place - on the shoreline, which moved.
The bible has elements that are right, and a lot of invention, that isn't.

Well, yes, humans exhale CO2.
But, please, don't stop to do that.
But in case of sea-level rising due to climate change I can assure you, that emitting CO2 by you has absolutely zero effect upon sea-levels.
First:
there is actually 'climate-change' as a real phenomenon in many places.
But that isn't caused or even related to CO2, but has other reasons.
Mainly the water is the key to understand weather. Climate is strictly local and the result from what is happening in a certain region.
For instance lets take a really nasty city, in respect to climate.
Lets take, for instance, Dhaka in Bangladesh.

What you see is a totally overcrowded city.
More than 24 Million people are cramped into a city build for 10% of that number.
Would you really believe, that this would not influence climate?
But how you exhale has nothing at all to do, whether or not the icesheet of Greenland could slide into th ocean.
The real cause is actually the water, because people need water, space to stay, to travel and to grow food.
All of this has influence upon how much water the ground could evaporate and that in turn has influence upon the creation of clouds and that in turn changes the climate.

I personally think, that the so called 'growing Earth' hypotheis is actually true.
This means, that the Earth grows by creating matter in large amounts inside the planet, which pushes upwards and puts the surface under horizontal stress, what creates narrow land-bridges between adjacent land-masses. Then these land-bridges break and allow sea water to flow inside the basin, that has build behind the land bridges.
This happens to the street of Gibraltar, which after opening allowed the Atlantic ocean to flow into the basin which today is the Mediterranean Sea.
Later the same happens to the land-bridge, dividing the basin that today is the Black Sea and the Adriatic.
When that land bridge broke, the Dardanelles and the Bosporus opened and allowed water from the Mediterranean Sea to flow into the area behind that land bridge.

How far-fetched can you get?
The point is that they are visible all the time, in direct conflict with the Noachian flood story.
No lack of shore lines that move, all over the world. The obvious one is the Persian Gulf moving into Eufrates/Tigris delta. (much faster, and just where it is wanted) There is where the story that those shepherds from the hills ripped off really happened,

Of course, it is a stibilised quartz clock. I thought you were proud of being an engineer, so I adapted the description.
Like I said, they are called 'clocks' but for the time being they are only frequency standards. (precisely because they cannot be used yet to stabilise a quartz clock)
From an engineering point of view that is just being able to count.

Bullshit, of course, anyone can check GPS, a Cs clock (together with your SI absurd) may be good enough for kiddish games of idiots like you, but it's no way stable enough for serious measurements.

When you are happy with a 1.4xyzzy GHz clock frequency, an active Hydrogen maser can do that without an XTAL.

(having locked a h-maser to a zero-g cesium. The maser has the better phase noise but Cs is the law. That was somewhat eased b/c everything was at 100 MHz already.)

The Galileo satnav system uses them, with somewhat mixed succes. Some have failed, iirc. And, also afaik, Cesium clocks can achieve better long term stability, (10^-15, for the fountain kind)

Au revoir, my formerly feisty foil.
LHC's tearful team twinning - scientism's spontaneous segue into schmaltzy soap opera stuffed with metaphor:
Chasing the Higgs
...
Now it had come down to the Large Hadron Collider, where two armies of physicists, each 3,000 strong, struggled against each other and against nature, in a friendly but deadly serious competition.
In physics tradition, they were there to check and complement each other in a $10 billion experiment too valuable to trust to only one group, no matter how brilliant and highly motivated.
...
The stakes were more than just Nobel Prizes, bragging rights or just another quirkily named addition to the zoo of elementary particles that make up nature at its core. The Higgs boson would be the only visible manifestation of the Harry Potterish notion put forward back in 1964 (most notably by Peter Higgs of the University of Edinburgh) that there is a secret, invisible force field running the universe. (The other theorists were François Englert and Robert Brout, both of Université Libre de Bruxelles; and Tom Kibble of Imperial College, London, Carl R. Hagen of the University of Rochester and Gerald Guralnik of Brown University.)
...
Everybody agreed that the Large Hadron Collider was the last stand in the hunt for the Higgs boson. Circling for 17 miles underneath the complex of aging postwar buildings outside Geneva (and out into France) that constitute the European Organization for Nuclear Research, or CERN, the collider was designed to accelerate the subatomic particles known as protons to more than 99 percent of the speed of light - an energy of seven trillion electron volts - and crash them together.
...
Many physicists, Dr. Wu admits, thought that she herself had leaked the report. A year and a half later, she still found it hard to talk about the Easter event.
"I was so excited I couldn't control my emotions," Dr. Wu recalled. She wrote the note as a way of alerting the Atlas community, she said. "I thought CMS would go on vacation and we could get ahead. I'm sorry I did that."
...
While physicists fretted about the death of the Higgs, something was happening out in the wilds of uncertainty. One bump on physicists' charts, from the W bosons, was disappearing. But another was blooming like the shy girl at a dance.
In retrospect, nobody could remember exactly when she had come in. But she was the one who would marry the prince.
...
Back in Switzerland that same month, during a break when the Large Hadron Collider was not running, Dr. Gross took his girlfriend, Talia Levy Tytiun, down into the Atlas cavern. "I decided that I want to propose to Talia in the place which was the symbol of my life at this Higgs hunting period," he explained.
"But believe me, I checked a thousand times with her before to make sure she will say yes."
...
The gamma rays were still there, and had grown in significance, putting the boson on the verge of reality. Dr. Gianotti scrawled a note back: "Oh, my God."
A week later, her team looked at another important decay channel, and her enthusiasm deflated. There was nothing. She spent a few days and nights with her "neurons spinning," she recalled, wondering how they could have been fooled. ...
If nothing else, she thought, her talk would be a valentine to the passion and competence of the 3,000 Atlas scientists. ...
"Every slide was a reward to the work of many, many people," she said. "So I was feeling so proud."
"I think we have it," he said. The cheers began again. Dr. Higgs was seen wiping away tears.
...
Dr. Wu waded through the crowd. She hugged Dr. Higgs.
"I've been looking for you my whole life," she said.
"Well," he replied, "now you have found me."

Time is a universal parameter of most theories of mechanics, and the useful ones.
It's also an implicit parameter among any interacting terms.
For example, "force is a function of time".
It's more than less what "meters" processes itself.
That time-symmetry/time-irreversibility has never been falsified, makes for that it's not falsified "there are no closed time-like curves".
"Counting" and "ordering" are fundamentally different, when one or the other of "theories-of-one-relation" has its elements "cardinals" or "ordinals", neither of which quite suffices to contain "number theory" or "geometry", given usual accounts of "invincible inference": the "invincible ignorance" of "inductive inference".
Then, time-keeping the time-base is for measurements related to time, "counting" is simply enough tossing pebbles into a pile or the grains of an hourglass, where the traditional account of "time-keeping" is that it's tossing pebbles into a pile to estimate when to pull the food from the fire, _after_ counting.
Heh, silly reductionists.

Time is a universal _absolute_ parameter.
About space-contraction as length-contraction and time-dilation together, has that clocks "slow" or "meet" about differences between "space-contraction-linear" and "space-contraction-rotational", breaking out the "space-contraction" as "-linear" and "-rotational" instead of "length-contraction" and "time-dilation".
This is a very euclidean account.

The stability of the cesium clock is used to regulate a lower frequency clock that gets counted. It's not any kind of "stabilised quartz clock".
You "adaption" misses the point.
The mechanisms that are used to force the lower frequency clocks that can be counted to conform to the stability of the optical source are fairly complicated, and I don't claim to know all that much about them, but they are used to fix the output frequency to a precise fraction of the optical frequency standard.

Think about Doggerland (now in the middle of the North sea between England and the Netherlands).
There were people living out there at the end of the last ice age.

It got inundated by a series of fairly dramatic events. Crawling babies wouldn't have done well. "It is estimated that up to a quarter of the Mesolithic population of Britain lost their lives".
The sea level rise tied up in the West Antarctic and Greenland ice sheets isn't going to show up as smooth and gradual rise, any more than the sea level rises that happened at the end of the most recent ice age did.
Who was promoting that?
And you know because your time machine took you there?
