Voicist 🔴 What Is Islam? ⚠️
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
@@ahmdabdallah2132 What does any of that have to do with quantum flux tubes?
@@ahmdabdallah2132 Yeah but ... quantum flux tubes though?
Surprised this glitch hasn't been patched yet.
It's because they agreed to a yearly patch. So we gonna wait a year. 😂
Not a glitch but it’s a strategy within the game
It’s viable

1) We didn't invented it, we only discovered it
2) It was actually discovered in 1911

UA-cam recommendation brought us together again.
Dunno why I don’t even know what quantum means
And so it begins... and so it also ends... We found eachother by random, and will separate as random. The chances that we will meet again are low, so i hereby wish you the best of travels through the world of YT recommendations, until we maybe meet again, so long
Enough with these copy paste dumb comments, try to think something original. Try to think!
WE STAND TOGETHER NO MATTER WHAT
Dsync yes indeed
I wonder how mindfucked the guy who discovered this was lol
Meissner ? Just wide-opened mind guy :)
Nicolas Tesla
Chu Ching-wu is the guys name and he discovered it in 1987, it's YBa2Cu3O7 (I assume that's what's used here at least) and is a warm superconductor, so that means it's cooled to the temperature of liquid nitrogen as opposed to liquid helium (which is what was being used since the 1911)... Granted, that's a difference between 77K and 4K critical temperature, making it way less expensive... Nowadays, this stuff is used for things like MRI's
Meanwhile walther meissner discovered this effect as a result of the superconductor blocking magnetic field lines from reaching from one pole to the other, levitating so that the field can be shared by the poles; because the superconductor has no resistance, circulating currents are induced to produce magnetic fields that cancel out the ones from the magnet, causing the net magnetic flux to be zero and allowing the magnet to levitate. Here, a perfect diamagnet is created by aligning the poles from the permanent magnet and the electromagnet created by the super conductor, so they are attractive yet repulsive
So yeah they were probably pretty stoked over they're paychecks
you can t fix stupid
@David Roberts its a compliment. Its like looking at bike or skateboard stunt and say that its a crazy shit or something. And yes, mindfuck, because you have to first be able to imagine, think and comprehend the relationship between supercooling and electromagnetism, apply it to math n physics and then develop it in real life.

Seems like a lot of people are getting this suddenly.
They must be ready to unveil something
theoretically, flying/ levitating cars would be possible if we had roads as magnets
Posibly as long as the car is completly cold
@@firtdudecoolmanplayer5357 like freezing cold, which is impossible
Maybe shipping objects is possible
This would be more like a train
Thats mean no fly...
Technically, the most easy way to reach the goal of "levitating cars" is making tires with sphere form, and in the interior of those would be a permanent iron.
(Sorry 4 my bad English *:(* )
Am i the only one thinking: TRAINS!!!!! TRAAAAAAAAAAAAAAAAAAAAAINS!!!!!

There is one in Japan
Helvanic That is maglev. This is slightly different.
iocopoco maioco Yes!!!! I was thinking you could even hide the rails in the street. Or make a suspended monorail that has no visible mechanism to hang from the ceiling or wall.
tjohn6041
That would be so cool!!! :)
You guys don't get out much do you?
It would be so cool if transportation systems were like this....Well, except without the need for sub freezing temperatures.
Can you cool it from liquid nitrogen just swimming on top of it?Like a pot?
Wouldn't the liquid nitrogen evaporate eventually because the item would be hotter than the liquid nitrogen, creating a pocket of nitrogen gas around it?
SmittenKitten I don´t think that will happen...
The laws of physics say that it'll just form a pocket of nitrogen gas around the object. It's why sometimes pools of water or oil on a hot pot/pan turn into little marbles and seem like they're rolling. Depending on the temperate of the object, however, it would not last very long, and would end up freezing, but it'd defrost very quickly because the surrounding temperature is much hotter.
SmittenKitten What if you put in in a fridge...
"The disk is locked in space"
"its possition can be adjusted"
I believe you ment the disc being "locked in the magnetic field"
Yes but what if that magnetic feild were made 360? Wouldn't it run as long as its cooled so if making a spaceship would it recharge by using the cold of space itself? I think adding pelter units could create a sizable amount of power to the spacecraft for A/C and electricity. I want to try to make a space ship i think i got it. But it would have to be circular. With the powerful magnet on the inside
Wait if that were the case the outside would have to be the magnet
Amazing. Congrats to who ever figured this out. Simply brilliant
Ah yes, flying pancakes. Just what I needed, UA-cam
That much less effort between the pancake and my face.

🤦🏾 💯 bro
Dont forget, the earth is flat! Lol🤣
There’s nothing “quantum” about this: it’s just that lenz’s law states that any change in magnetic flux through a conductive loop will create a current that will create a magnetic field that will cause a force oriented against it’s source. So the magnetic flux doesn’t change, because if it did it would create ideally infinite eddy currents in a superconductor. So the superconductor stays where it is
Yes you are correct but same phenomenon can be explained in different point of view. Remember Newtonian Gravity and Relativistic Gravity.

Quantum Election
Honey you remember that sapphire I got you for our 35th anniversary? Run it!
Absolutely fascinating! I could play with this all day! I'd think up various obstacles to create a kind of rollercoaster track where I could almost get a perpetual motion. A never ending, constant action/reaction affect except for one problem... When the temperature of the superconductor goes up, quantum flux tubes disintegrate... Perhaps the other fascinating characteristic of superconductors is the way they will maintain ANY position in a given space. 15 degrees or 35, 40, 65 92, 07, etc., etc. ANY angle as if it were a spinning gyroscope.
I know that the superconductor was discovered in 1911. But I remember learning of this first High Tc superconductor when it was first discovered in 1986. It hit all the news stations and at the time, all they demonstrated was a black, hockey puck-like object floating weightlessly above a magnet after it was taken from a dish of liquid nitrogen. That was it, LOL!!
They didn't demonstrate anything more than that but I knew I was looking at something a lot more significant than some kind of "cold magnet being repelled by the like poll of another cold magnet", which is what one or two of my brothers dismissed the demo as.
They and several other people I spoke to about the previous night's TV news announcing this new "Superconductor thing" all failed to see the importance. They likened it to the mag-rail trains in Japan. I tried to tell them that this was very different on so many levels but they really didn't see it.
I couldn't really blame them because the first televised announcement was so typical of poor, 'slam-bam', hack-job journalism. It lacked any detail or explanation let alone the physics that drove it all. 34 years later and you can bet that the "known applications" of this superconductor and its various spin-offs barely scratch the surface of what's really going on.
Unfortunately, there's the organizations that have applied it to weapons and they then lock it up. But if they'd only use some of the money and motivation to apply it to clean-energy operations and transportation, it would be a much more worthwhile endeavor. The problem is that once a military operation finds a new destructive use for any new discovery, they lock it up so that it can't be expanded into the uses for commercial and/or civilian applications.
This endless circle of discovery-to-military-to-public blackout has and will continue to get more constricting. It's been holding us back from commercial earth and eco-friendly advances for decades and I think it's behind our failure to convert all transportation to an alternative form of locomotion.
FWIW
That's just too awesome! Thanks for teaching me something new and entertaining as well. Good Day to you Professor.
Levitation, amazing science, I hope it can be utilized for good use in near future !
Supermemo62 LoL
Well the superconductors that result in this levitation allowed mri machines to be much less expensive as a result of only needing to be cooled by liquid nitrogen as opposed by liquid helium
Superconductor + Earth Mag Field = BTTF Hoverboard?

It isn't levitating, it's simply failing to fall.
It is levitating, electromagnetism counteracting gravity is considered levitation.

so thats how the aliens travel in flying saucers, except they use the earth as the magnet
I've heard the Earth's magnetic field is to weak for that, but I'm sure a superintelligent advanced civilization could figure out how to amplify it for a ship. I'm also wondering how they change their position so easily without an outside source of force. Maybe they adjust the superconductivity in a way that allows for movement?
Except they wouldn't be able to move around the earth because they are locked into the magnetic field arrangement

Jigglypuff Some day some ufos may use some form of mercury/plasma suspended in a rotating electromagnetic field as it’s frictionless in a similar way to this experiment.

The vaccum of space is. The many energy-generating objects in it, however, are really, really hot.
I’m a big fan of trains, my grandfather had a very cool train set toy… it would be awesome to have a train track made with magnets and have superconductors move along the tracks in different ways, even upside down lol just a fun idea 💡
If you like this check out the hoverboard that using this technology its made by one of the big car companies too and theres a skate park where you can use the special board thats super cool

with such great music everything is beautiful.
This was it cool experiment and thank you for using appropriate music.
fricctionless, there's air fricction, theres just not fricction involved between the lane and the super conductor, this is cool but not energy efficient, as the superconductor needs to be super cooled, and that takes a lot of energy.
I like that; it does require "taking" the energy as opposed to putting energy in. c:
Does anyone know where I can buy the sapphire crystal?

Then look for a lower tech way to recreate the experiment
If you freeze a superconductor in a magnetic field and then take the magnet away,
does this turn the superconductor into a super strong and light weight magnet?
How high could this levitate over magnets?
Would it need a spin for stabilization?
place that magnetic disc inside a vacume with the object levetating and it eliminates air friction.
and make it travel with the speed of light
Ivan Ivanov lol
What if someone did that and so it went forward in time and then in the future someone discovered it and thought it was pretty cool so they based their technology of it and then went back in time and want to thank us but can't cause we keep thinking their hovercrafts are hostile?

***** What if they have? maybe their technology is so advance that they have super invisible cloaks
I wanna know the math for force applied and force absorbed then I would like to know how to calculate/determine the information for the calculation depending on super conducting material, is there a level of superconductivity? If there is how is it determined and what is the evidence?
Also is that superconducting level directly connected to the amount of force that is able to be applied with out breaking spacial entrapment aka motion or “the first question asked” or are all my thoughts wrong and should I have not asked these questions yet.

Will the magnetic disks carry an non super conductor atop of it while it's levitatating?
It already does....aliens man!
I’m kidding(maybe), but that be cool if it was strong enough to carry a load.
What if the disruption was longer? Would that cause the connection to disconnect and fall off? And if so... what is the fields breaking point?

Are the poles magnetic fields to big enough to do a similar thing? Also what makes the levitating object go up or down? Is it the magnet or the cold? Have you ever changed the variables in mid hover?

I have some questions. 1) I want to recreate this, but need to know where to get/how to make the 500 micron thick sapphire disc 2) Why didn't you apply the coating to the permanent magnets in the first demonstration.
So does the superconductor need to be extremely cold or can it be extremely hot and work as well? If so lightsaber possibility.
JackManic1984 No, presently it can't even be room temperature and work, so extremely hot would definitely not work.
JackManic1984 I think high enough temperatures will stop the magnetism altogether
JackManic1984 it is that the object's resistance depends on it's temperature (see: electricity) and basically super conductor has zero resistance, hence 'super conductor'.

Very very interesting. Could you tell me what is the geometry (NS poles of the different magnets)? Are all inner ones with N up and the outer ones with S up? Are all of them oriented NS radially in the same direction or opposite? Are they alternating? Thanks!
This is just Mind Blowing!!!
Correct me if Im wrong but it loses velocity as it travels along the ring because though the flux is constant along a magnetic ring theoretically, the realistic factor accounting into the superconductor to lose velocity is due to friction occurring for flux in actuality is 0.99 or so rather than ideal 1?
Air resistance is always a factor when you're in air.

This is nothing new... ohh wait, UA-cam recommended this after 8 years🤔
There's probably a v4.7 by now😒
Or it has been patched with new physics update
how do you not do this all day?
So let me get this straight. If the disc is not touching anything other than air than the only thing creating friction is the air resistance? So if you do this in a complete vacuum would it not create perpetual motion?
If you increase/reduce the power on an electro magnet can you force the disc to rise/decend ? Also how can you maintain it in a supercooled condition?
