The Physics of superconductors
HTML-код
- Опубликовано: 25 июн 2024
- How a superconductor works. Everything from the physics and some of the history as well. Superconductors were discovered in 1911 by Heike Kamerlingh Onnes. It was discovered because it was made possible to liquefy helium which produced temperatures down to 2-4 kelvin.
It was then discovered the resistance drops to 0 after the critical temperature. It is explained by BCS theory, how two electrons goes from fermions and bonds into a boson.
This theory can be used to leviates trains or everything. Explained by the meissner effect. This video only cover type 1 and not type 2 superconductors.

It was great have Arnold Schwarzenegger narrate this video and show his interest in physics
Man i wish people would call me the Arnold in real life! I should start bench pressing some more
@@Higgsinophysics like your voice its cool, learn some of Arnold's favorite lines and words from a sound board... the more you sound like Alrnold the more subscribers you'll get ... it worked on me because Arnold is cool.
@@Higgsinophysics some moah*
Lmfao, anyone else read the comment before hearing the voice.
😂
I imagine these videos take a while to make, fantastic job once again.
yeah they do. But most of the time it's fun!
@@Higgsinophysics good that you enjoy making it coz the content will be fun to watch and for you, time passes like a breeze. You deserve much more subscribers
@@turbothrottletrouble4217 1 more subscriber. Thank you for doing this and phenomenal work.
3:09 wasn't expecting the meme LOL
who is this WHAH guy? lol
@@AntonySimkin A Christian pastor. Says "why" alot. I do not know his name lol
A few remarks:
- The most used superconductors, NbTi and Nb3Sn, are both type 2 superconductors but are also explained by BCS theory. BCS doesn't work for the high-temperature superconductors (HTS), like the ReBCO and BSCCO compounds.
- We know, phenomenologically at least, quite a bit about how type 2 SCs work.
- The Meisner effect, which you describe when talking about floating, is far too weak in most situations to make something float. You need flux vortex pinning in type 2 SCs.
- The flux vortices don't expel the magnetic field, they let it through, one flux quantum per vortex. Because it costs energy to move these vortices, the material tends to keep its position and hence can float
- Type 1 superconductors are almost useless in practice
Still, your explanation of what is simply is, the history, and especially the explanation of BCS is very nice
he said in the vid type 1 superconductors are the talked about super conductors.. they dont know how type 2 super conductors work so why are you saying type 1 s uperconductors are almost useles in practice!?!??!
@@SmethiousReborn he's saying the majority of the things higginso said are for type 1 are actually for type 2. so all the cool stuff happens with type 2 conductors not type 1
I'm working on a paper about superconductivity and man, I gotta say, this 8 minute video did so much more for me than staring at my modern physics textbook for half an hour. Keep up the great content! Subscribed
I love to hear when the videos can be used like this. Thank you for sharing!
Hello Stephen, I am an IB student working on an essay on superconductivity as well, specifically the transition to zero resistivity. How did the essay go? I would be extremely grateful if you would send it to me to help me on my research!
Thanks
Seriously? I can't believe, this is so Underrated!
Dude whats up with profile pic? I know him.
Great video. Thank you for the work you put into your simulations, it makes everything so much easier to understand.
In my biology class, we were talking about diffusion of water across a membrane. The teacher asked if the molecules would simply stop moving once equilibrium is reached, and I answered "no" because I remembered one of the simulations from your entropy video. The particles keep moving back and forth, and the multiplicity still stays the same. Thanks!
iPeaceful nice good job man - and thanks for telling me. It’s really nice to know you got something useful out of the videos
A gem has been found
You explained everything crystal clear in just less than 9 minutes.
That's what we need in our school physics lectures.
When the video cuts to “why???” I nearly spat out my coffee! What amazing timing for that edit! Thanks for this awesome video:)
Teacher: temperature coefficient blah blah ( concept unclear)
He : hold my helium
👍👍👍👍👍
Wish I watched this 2 years ago when I worked on my thesis
it hasn’t been out for 2 years yet
For year 12 we have to write an article about any topic of our choice and give a lecture in front of our class,and have to pass this to get into yr 13. Its not too hard but I kinda now that feel since I have already written multiple articles where there was barely any material to learn from until I finish my articles. It's really annoying.
What did you do your thesis on?
bro can you pass me your thesis pls?
Probably the best visual explanation about electrodynamics of the supeeconductors I've ever seen. I'll definitely subscribe to this channel.
Incredible how your 9 min video explains the topic way better than my entire 90 min lecture! Thank you, keep up the grat work :DD
This video was incredible! I learned so much and have a new found interest in superconductors, I cant wait to go dive deeper!
Glad to hear that thank you
THANK YOU for going into more detail!! Several videos about this topic, but none of them really explain much.
np glad you found it useful
ONE OF THE BEST EXPLANATION, I EVER HEARD
That example made with lightning and the conductivity of air was magnificent! Wow.
Thx, this helps me a lot. This's the best animation of BCS theory I ever watched.
its really fantastic..... I was searching for a long time about quantum levitation and ur video really solved my doubts.....thanks a lot
Thanks so much, been looking for this for quite a while
one of the most didactic explanation of superconductivty I've ever seen! thank you! cheers from Brazil
Did you hate my pronunciation? Content of video is in article format here: higgsino.medium.com/the-physics-of-superconductivity-8631a174f986
Your pronunciation is perfectly fine. European accents are much more preferable than an Indian accent...
@@clemeschmidt Indian accents just pronounce every word strongly? don't know how that's bad
Once again i came here really loved your videos thanks for uploading.
Very good video man, super informative, got a lot better understanding of superconductors now
by far the best video on the topic, super cool job!!
Great, thank you! This was very clear to follow and understand.
Thank you! This was fun to watch
Thanks so much! You have just helped me so much with a superconductors project I am doing in Physics.
glad I could help
I loved this video especially the animation!! It made the whole content so much easier to follow!!!
If you dont mind telling me how do you make those animations, I've recently started teaching a class and want to give a go at it🙈
It’s been 3years since this video was released. My professor didn’t really explain superconductors last week and then just skipped to next new chapter by leaving a series of questions in the homework. Thanks for the video so much, it makes a lot of sense and make superconductivity so interesting to me!
A good curation of internet material is far superior than any university course if the material out there exists, and isn't cutting edge info that only the researchers themselves have.
But professors rarely ever teach a class on their cutting edge material anyway.
@@gwho Kinda. The advantage of courses is feedback. If anything unclear you can often ask and get a direct answer way more easily than with the internet. Perhaps more importantly you get various knowledge checks so you can get feedback on things you didn't know you didn't understand. Though admittedly there is a lot of great stuff out there that can be more engaging or explain things better than some course can do in person. So there are pros and cons.
I just heard the news about LK99, sounds really amazing, would you please make a video about this material? Thx
its really wonderful representation. thanks
Awesome 👍 just found your channel. Great work you did there . Thanks for your effort.
thank you!
Visiting this video to find out what and what isn't possible with superconductors, now that a potential (it is not peer reviewed yet) type 2 super conductor could do for our society!
Such a beautiful video
So nice of you 👍👍
Yo super high quality amazing stuff bro
Thank you i appreciate it :D
Difficult things made simple thank you sirs, very much appreciated
Great explanation! Now I need to learn more about cooper pairs...
What a good explanation!
wait, what ? So, the resistance is ABSOLUTELY, PRECISELY, MATHEMATICALLY ZERO ? as in NULL ?
OMG I mean I always assumed when they did the levitating superconductors thing the Eddy currents would eventually give way to gravity by bending eversoslightly and losing energy, but I guess that was just the temperature rising
I mean I can't put into words just how INCREDIBLY NEAT that is
Like, you would think that doing something like bouncing a lightbeam off of a spherical mirror would last forever, but it doesn't, and so many things in this universe bow down to entropy's clenching iron fist
But the fact that you can have current going through a superconductor FOREVER just blew my mind
I exaggerated a bit because no matter what we measure there will always be some uncertainty in the measurements. So we don't know for sure that it is ABSOLUTELY, PRECISELY, MATHEMATICALLY ZERO :D But we know for sure the resistance is as good as zero, there was no intensity loss measured outside the uncertainty.. Also NULL is not zero it's nothing :p
There's also "time crystals", which are little quantum "perpetual motion machines", going theoretically forever without losing energy and increasing entropy.
Nature is flippen awesome! Well presented. Thank you!
Video contents is SUPERB , AMAZING
but...
Do the background black only for eye comfort.
Thank you for this video. I have been trying to learn about superconductors through reading the new papers on the ultra pressurized superconductors, but everytime Tc showed up I kept wondering "Why does the temperature have this effect?" Thank you giving me a start on why temperature gives this effect.
wow what a good explanation of this phenomenon! Thank you!
Thanks friend
Great video! I really enjoyed the animations :D
Thank you!
Hello from the future!
Nice simulations for the electron ball and chain. My idea for the next video - Superfluidity / bose einstein condensates!
Thanks for the suggestion. It would be a nice continuation
This video was so well done. Your animations look great. Which software did you use to do them?
Great explanations, awesome graphics
Great work!
Nice video, great explain. I can imagine how it works by this video.
glad to hear that :)
Excellent description of the topic
Thank you very much
Fingers crossed a type 2 may have been discovered

so helpful thank you!!
Amazing video very helpful thank you 😊
very nice explanation
It’s a great youtube channel that comprise exact and complete physics details in it❤.
Thanks for those kind words @hosseinrajabi3885!
Great VOD man realy helped me out im doing a project about maglev and i need to understand superconduction
Amazing video, thanks!
an amazing explanation
I learned something. Thanks
Great stuff!!
Excellent video...made me imagened what actually superconductors are...thnx
You make the internet smarter and more worthwhile
that was amazing!!! a satisfying video after a long long time!! n btw, i subscribed!
thanks for this kind comment!
Kudos to the explanation
It was a great explanation
Thanku sir for this effort. My concepts are much better now. Thanku from bottom of heart
awesome stuff!!
very good explanation!
thank you great vid! no cap. Type 2 semiconductors sound even more interesting.
Excellent vidéo !
I love that I can use this video to show not just superconductivity, but conductivity, temperature-dependence conductivity, and resistance as well. In about 8 minutes, you taught an entire three-hour lecture for me. WHY?! Just kidding. Thank you for obviously taking a lot of time to illustrate it all so well.
Glad you think that, it was the goal of this video. Thank you!
amazing animations!
my man helping me with my physics homework here
Nice explanation
Tq so much for sharing your knowledge with us
It's my pleasure
Superb channel. Great explanation. This video combined with Arvin Ash’s video gave me an adequate understanding of superconductivity. My first NFT purchase will be from you good sir.
The day has come with room temperature super conductor
that was super interesting
great video
Amazing , I luv it ♥️
This video earned you my sub
well my question is how scientists observe those microscopic level moments/phenomena
I think they don‘t. They theorized it and try to prove it wrong until the can‘t. So those are just humans assumptions/perception of nature. Sometimes they can be wrong or not complete.
This is a remarkably intelligent video
Appreciate your comment - thank you.
Physics is nothing but a simple concept which is oversimplified with fancy names
Great video
Awesome graphics
Nice work, I think I might have bumped into super conductivity somehow. Cheers..!!
This is what every collage and modern day physics should be working on.
@Higgsino physics Great animations. How do you make them?
Thank you! I use Cinema 4D but i would like to switch to blender soon. The Python module isn't too good in Cinema
THIs was a great video! Help mE a lot!
Amazing bro❤️❤️.
I LOVED IT
Nice video! just a small note, there are no maglev trains in existence that make use of this property. The one showed, the Transrapid, doesn't make use of superconductivity at all. The SC-Maglev in Japan _does_ use superconductivity, but this is to be able to create extremely energy efficient magnets, because no resistance means no energy lost.
oobs. Thanks for letting me now !
Thank you sir.
you deserve much, much more subscribers
appreciate your comment ❤️
Underrated channel
thank you
Why doesn't this channel have a million subs?!
