they seem to be making more of it than I can see a reason too.

like they are tacking on all the probability shit for reasons I can't see.

To take up the coin example again, when the time crystal breaks time-translation symmetry that means that it is making a particular period in time special, which would be like having a 50/50 chance with the coin now, but knowing that if you waited a certain interval of time, say 10 seconds, those odds would change to 75/25.

if you can predict it, then it isn't useful for random numbers.

but whatever...

2016 that a group of physicists working at Station Q, a Microsoft research facility at UC Santa Barbara, figured out a way to correct the theoretical problems with Wilczek's time crystals and provided the stepping stone to actually make them

if microcrap is involved.. it is probably not good.

The description of what it is, strikes me as very similar to "spin glass" - a so-called "meta material" - which while it sounds like something you build a space ship out of;

For physical systems, such as dilute manganese in copper, the freezing temperature is typically as low as 30 kelvins (−240 °C), and so the spin-glass magnetism appears to be practically without applications in daily life. The non-ergodic states and rugged energy landscapes are, however, quite useful in understanding the behavior of certain neural networks, including Hopfield networks, as well as many problems in computer science optimization and genetics.

Little bit more here, for a few minutes (or as long as you want, lol)

He also talks a bit about Bose-Einstein condensates at 28:15, which relates to the Time Crystals too.

Edit: If I understand his explanation correctly, is that the Bose-Einstein condensates are a kind of barrier to the universe sharing/updating the "blockchain ledger" with the rest of the atoms, allowing you to.... break the laws of physics

Read the article still dont really get it but it sound like the crystals can change their particle arrangement and whats freaking out the scientists is that if they stimulate the crystals with lets say a laser the crystals will shift but its random. One pulse of the laser can have them shift once, twice, three times. Its random and they don't know why?

As I understand it..
In the experiment they are using a bose-einstein condensate.
That means that the electrons are at their lowest state and will behave more like rotating objects.
They are also more synchronized.
Because there are more levels of rotation, this rotation of the outside electrons flip periodically.
And with this the magnetic field flips, and this is what is recorded in the video.

I keep adding updates, so this post also becomes a library of related subjects.

Virtual Particles: What are they?
Written by theoretical physicist.

And this is the product of 50 years of pure theoretical physics:
1. Virtual photons are "ripples" of the photon-field.
2. Forces are transmitted via these ripples.
3. Photons are ripples/disturbances in the electron-field.
4. Particles are not simply objects.

So this is a very complex way of saying:
"It is like the electromagnetic field"

Corrected with electromagnetic field:
-> 1. Virtual photons are the electromagnetic field.
-> 2. Forces are transmitted via electromagnetic fields.
-> 3. Photons are thresholds at the detector.
-> 4. Particles (Fermions) are collectors of electromagnetic energy.

The problem is that Feynman and Dirac tried to explain everything with particles first.
And when that did not work, imagined fields that produced those particles.

But we already have fields to begin with.

The reason why fields were abandoned is unclear.

It could be related to relativity.
Relativity regards fields as time-less, where particles travel through space/time.
But if you have changing fields, you have to reconstruct a different system for relativity. To avoid this problem, the theoretical scientists have created different, extremely complex problems. And because most of the theory is hidden in invisible stuff, we can not even verify it.

Now compare the loop with this plasma current loop on the sun.

There are clearly electric currents in the plasma moving the material in both directions. On the sun the magnetic field is outward compared to the Thomson experiment. That is how they rise up from the solar surface. This makes the loops far less stable, and you can have a multiple smaller loops next to each other.

What is the problem?
Rubies can be made from very hot Alum. Oxide with some Chromium.
That is the chemical composition.

In this experiment it is shown that you can make rubies by using the hot plasma that is created by small AL wires.
In another experiment he just uses a very strong electric current.
The rubies are low quality, but the experiment is very simple. And could be demonstrated in a class room for example.

I think that the high electron temperature of the plasma or electric current is making the chemical reaction possible.

The person of the Channel also made rubies with strong electrical currents. They gave bigger rubies instantly. I think this experiment could be done in your own garage.

It might be interesting to convert it to some kind of sputtering process, so you can make your rubies as big as you like.

Those were some pretty disappointing looking rubies. Interestingly both rubies and sapphires are the same thing, Corundum, a crystalline form of aluminium oxide. You can get the artificial stones for about a buck a carat retail, although if you want them used in commercial applications like making a pair of prescription glasses that can resist small arms fire (and yes that's a thing), it's quite a bit more expensive.

Null-Hypothesis - Quantum mechanics shows that there are no photons by zyxzevn in Physics

[–]LishLash 2 insightful - 1 fun2 insightful - 0 fun3 insightful - 1 fun -  (0 children)

Electromagnetic fields propagate throughout 3D physical space, which makes them inherently relativistic. Pilot Waves do not propagate in 3D physical space, they manifest in complex-valued Configuration Space, which is inherently non-relativistic. Pilot Waves are produced by the evolution of the quantum wave-function, evaluated via Schrodinger's Equation. These solutions are expressed as superposed complex-valued probability amplitudes in Configuration Space. Physically realizable solutions are projected into 3D physical space as probability density fields, according to Born's Law (= the conjugate square of the probability amplitude), which Bohmian Mechanics derives from its Quantum Equilibrium Hypothesis. The probability density field is not a physical entity, it is just a prediction of the likelihood of detecting a particle at any specific point in 3D physical space.

According to Bohmian Mechanics, relativistic particle trajectories do in fact exist, but their sole property is the actual location of the particle in 3D physical space at any point in time. That physical trajectory is the sole "hidden variable" in Bohmian Mechanics, and as shown by Bell's Theorem, can only be a non-local hidden variable (in order to remain consistent with QM). All other properties that can be measured are not those of the particle itself, but of the Pilot Wave that guides the motion of the particle. What BM contends is that in practice, the only things we can actually detect are the 3D positions of particles. If particles did not manifest in 3D physical space, there would be nothing to detect, since the only way we have of detecting e.g. an electromagnetic field is to observe how it deflects particle trajectories.

The non-locality of the Pilot Wave is the inevitable result of it manifesting in Configuration Space, which like the quantum wave-function itself, is inherently non-relativistic. This means that unlike the relativistic propagation of electromagnetic waves in 3D space, Pilot Waves propagate instantaneously throughout Configuration Space. This non-local (i.e. non-relativistic) property of Pilot Waves is what is misinterpreted as "faster-than-light information transfer" by those who mistakenly assume Pilot Waves propagate in 3D physical space.

I thought I knew what you meant by a full set [but was wrong]. It means all sixteen types working together on a project or toward a shared goal. Right? I read Logician very carefully a few months ago when you analyzed me and must admit the description was amazingly close. I am definitely introverted but not to an extreme. And intuitive seems to fit. I was amazed really. Do you use a computer to analyze our comments or rely on your own intuition and experience? Is Magnora7 a Commander? He comes across to me as that type and I mean that in no way negatively. The problem is he must be really busy now that Saidit has jumped about two quantum levels in a few months. So he probably has no time for this. And isn't being busy and not wanting to waste time one of the main traits of a Commander? Yes, it is because I just read it.

I can't keep up with the paradoxes but here is a fun math game you may know:

Choose any whole number from 1 up to as high as you want. Multiply your number by 9. Add up the digits of the product (x times 9). If the total of the added digits is a number with two or more digits, add them together until you have a one-digit number. From that number, subtract 4. Now convert the number to a letter. For example, 1=A, 2=B, etc. So now you have a letter. Think of an animal, a mammal, with an English name that begins with that letter. Now go to the next letter of the alphabet. For example, if your animal was bear then the next letter would be C. Using that letter, think of a country whose English name begins with that letter. When you have thought of an animal and a country, scroll down about ten lines and I will try to guess your answers.

My Escher is a Swiss professor of mathematics mostly sciencing about evolutionary equations in the time i had him. I didn't follow his work further since i switched universities after doing analysis one, two and three of his. And i went into combinatorics and algebra so i was not that into his flavor of math when i majored.

But at his best times he was the only named German-native scientist in the top 100 of the world.

Teaching-wise he was quite "difficult" because he mostly followed his own books and i still remember him doing serious mistakes when proving the Banach-Tarski-paradox e.g. . But his jokes were quite cool if you could wrap your head around them.

Live as if you were to die tomorrow. Learn as if you were to live forever. — Mahatma Gandhi

I think that's what you meant and it distracts from the fact that I know spit about mathematics. I didn't mean that all academics are charlatans but their number is higher than in most fields.

Will read the story again since I hadn't considered that it was faked. She's tall and attractive—no, I don't mean it that way—and tall, attractive people always have an advantage.

Did you mean MC Escher, the artist? No, I expect it was a teacher of yours.

I honestly know only two doctors that earned it: One is called Escher and the other one Schwarz. These were the guys that actually taught me a thing or two. Obviously they were rather into real sciencing, so into mathematics rather than hanging their brain away when entering a room.

Which obviously isn't a requirement when you study secondary or ternary sciences like the medical one.

Real humans never stop studying. E.g. i am doing electrical engineering right now even though i am a proven professional in mathematics and geodetics already. Despite me hating their fucked up notation and "always consider the lesser evil"-attidute. When hooking up a circuit. What i really learned in this new science of mine so far is:

You gotta do it the other way around.

Not involving Lagrange, Hamilton even Eulerian angles into a simple rotational problem like this one is can only concur with one assumption:

She never tried the shit she claims to be doing.

Centre of mass calculations suggest she broke her arms elsewhere and this one is photo-shopped.

So you don't think too highly of doctors, lawyers, physicists, and Jews. I will not comment on that but I like your skepticism and attitude. What's the backing for my proclamation? It involves alcohol. Years ago a neighbor of mine was a doctor and a few times he invited me over for a drink or two. Once, the topic came around to jumping: in front of trains, out of windows, whatever. He told me about the ten-floors-to-concrete rule of thumb. But he said it's just a generalization and a bad fall or a well-executed jump from the second floor could also do it. I don't recommend it to anyone and I'll just let nature take its course, probably.

He also told me: we have some of the best doctors in the world in this country, and some of the worst.

Have you ever heard this saying that was no doubt thought up by a physicist? Biologists only talk to chemists and chemists only talk to physicists. Physicists only talk to God. This paragraph was just to round out my comment.

One thing I've learned so far in life is that there are a helluva lot of charlatans in every field I've come in contact with but especially academia.

Cheers

Where is your middle-school-grade calculation backing this argument ? She could be catwoman. Possibly even is considering her broken arms and unbroken neck.

Most medical students fail badly in their first test in "Physics For Medicine" and there IS a reason for this. :)

Real men do mathematics. Then you got the physicists raping mathematics for the first time with some bs reality argumentation. What kind of human with at least some imagination gives a fuck about reality, right ? Then you got the engineering and IT students raping it for the second time with some Landau bullshit claiming that every term above O(x³) isn't relevant. So in their world every problem is deterministic and basically locally (which they without any thoughts extend easily to globally) a Galois-reducible polynom. And after that come these ternary sciences like social sciences, business, medicine and law raping it again.

No wonder most medical doctors are basically drug dealers with a degree hanging in their office. No real scientist (except for medicine, obviously) gets his doctor after a mean time of one year of sciencing a little around here and there around the edges of his profession.

No wonder most politicians and lawyers are basically idiots when you take a look what pile of bullshit they most likely studied.

Following this plausible argumentation it is even easy to derive why the world is ruled by jews: Because they most likely believe in every bullshit they are told to believe.

I'm not even talking about indeterminism. A classical universe with time travel still posits infinite copies of the universe existing all at once for every moment of the past (and future).

This paper seems to be re-treading the same path as the Novikov self-consistency principle. The conclusion is the same in either case: Time travel is not possible when it creates paradoxes. It says nothing about possibility, only about impossibility.

For all that we know, all attempts at time travel may be impossible, since they may always lead to paradoxes. In this case, even if you could build a time machine, it would automatically shut down every time you tried to use it.

It's also flawed in that it posits that in every moment of time there is a copy of the universe.

Not quite. That supposition comes from a particular interpretation of quantum mechanics, which most call the Many Worlds Theory. This is a very controversial position among scientists.

The concept of time travel is flawed. If you can travel in time, then time is just another physical dimension. But then to be able to move in that dimension, you need another dimension of time. It's also flawed in that it posits that in every moment of time there is a copy of the universe. Time is really just a way or organizing change in a system. The past doesn't exist. There aren't infinite copies of the universe in various states.

Whenever the public good (forests, land, environment, etc.) can buffer negligence, THERE WILL BE NEGLIGENCE in favor of profits.

This reminds me of a scandal of a Canadian toxic waste disposal company called, IIRC, Laidlaw, which instead of properly disposing of the toxic waste they got paid to manage, drove into the forest to lands bordering the US and just sprayed this unbelievable crap into nature. Profit. That was back in the 1990s. Just as another example.

And this is why corporations as legal persons should not exist and it's also why the current form of capitalism is doomed.

The insidious use of light and dark to imply...what about the Universe (what the fuck does a human learn by these words?...nothing of depth)? Simple dualities to create ambiguity and confusion of a simple concept that these simple dualities describe a whole, an entire subject, they are not separate. So, the Universe is light and dark...WoW what an insight.

The parallel between the "neural network" and the universe,
is that both have electric paths going through them.

In mainstream these paths are claimed to be "dark matter". They show up as small lines between galaxies. But you can actually detect the electromagnetic fields with the Zeeman/Stark effect and/or the cyclotron radiation. This indicates that these are plasma currents.

There's an easy way to fix all of this. If any research at any point uses any government funding whatever - indeed if anyone does - 100% of the results and processes must then become entirely open and available to the public. No profiting from the funding of the citizenry as if you've a right to free money for private enterprises. Universities receiving so much as a penny should be forced to make all their research and everything else fully transparent. All of it.
