I just defended my dissertation on Fe-based superconductors, and I found this video incredibly useful. Understanding things on a deep technical level is completely different than being able to understand it in simple terms and communicate it easily to a general audience. Like Einstein said, if you can't explain something simply, you don't understand it well enough.

Thank you for making these maps, it takes subjects that are not necessarily digestible by everyone and breaks them down to where even non-physicists can understand them, all the while still being respectful of people's intelligence. Much appreciated!
Nice map and I enjoy your videos. I would like to mention an additional and interesting technology made possible by superconductors. Superconductors can be used to detect light on the single photon level with great precision. These superconducting nanowire single photon detectors SNSPD work by breaking down the superconduction of a wire when a photon impinges on a superconducting wire. They are around since the early 2000s and are used in the field of quantum optics. Currently the SNSPDs are setting the gold standard for single photon detection and can achieve a near unity detection efficiency.
@@alwaysdisputin9930 Not quite, the energy of a photon is big enough to break apart Cooper pairs. Once you Setup a hot spot with a normal resistive spot heating will kick in and the entire wire becomes resistive. The resistance can be easily read out. The layout of the super conductor line is critical to get it working. www.researchgate.net/profile/Chandra-Natarajan-2/publication/224836704_Superconducting_nanowire_single-photon_detectors_Physics_and_applications/links/00b49533b7632e3570000000/Superconducting-nanowire-single-photon-detectors-Physics-and-applications.pdf?origin=publication_detail
A very nice and well done quick overview over a complex field which hit the sweet spot of not to trivial to be wrong and not to complex to kick 99% of the people out very well. One thing for the back side of the map: the magic angle of bilayer graphene.
Great video! I am a PhD student in mechanical engineering and focused in thermal energy systems and sustainability. That being said, I have zero background in this subject haha. This was super informative and easy to digest. Keep making great videos!
I love your pictures about the map of the science series. How about making those maps not only a poster but also a mouse pad? it would be really fascinating and I'm sure that many people would like it.
yep ! I like vids like this, a guy who has temporarily reduced his clock cycles down to our level and made a informative vid on a tricky subject, could do another on the latest REBCO types and so on, especially the methods of attack on the critical field and current issues, sub most certainly earned, well done.
I work on a team that builds superconducting electromagnets and I do not understand them well yet. We have physicists and engineers who understand them so I am safe but.... I am really interested in learning all I can about everything related. This video made me happy. Your delivery is interesting. I wonder if you used sarcasm if it would be detectable.
There are books out there that break things down and give you the big picture just like you do in your videos. I appreciate what you do because those types of books have always been among my favorite.
Thank you for this video! I couldn't understand a thing from my graduate quantum mechanics course on BCS theory, and it's nice to finally know what it is about xD
Masterful job. I agree with your earlier assessment that its not always necessary to show the kill, but occasionally it drives home the point that wilderness living is bloody at times and food/hide procurement means killing. People need to see it done with a professional dispassion in order to to realize that there is nothing cruel about it, its just a part of the cycle of life. A predator killing prey is much messier and less humane than is a hunter dispatch, but both are thankful for what nature has provided.
We got the room temperature superconductor without a quantum computer... the superconductors coming after the LK-99 Quantum Computer will be beyond sci fi
Another future application I think could be is energy storage. If you can get electrons to circulate freely inside a superconductor with no resistance, wouldn't it be possible to let them run indefinitely, therefore storing their energy for later use?
That seems reasonable, provided the current stays under the critical current or whatever he said? Also, I think maybe that would induce a large magnetic field? Not sure whether or not that would pose a substantial engineering problem.
Dear Dr. Walliman, I am sorry, that I have to mess up your beautiful map, but superconductivity using magnetic levitation trains have been around for quite some time, the fastest of them are currently reaching 600 km/h in Japan. It's not future, it should be moved to current applications. Nonetheless, I greatly appreciate your work and am looking forward to seeing more!
Thank you Andrej, you are right. I should have looked this up before, rather than just relying on my memory which told me that the Maglev trains ran using regular electromagnets. But just looked it up and you are totally right! :)
Im surprised there's so many applications to civil engineering in one quantum field. Lossless energy grid? Levitating trains? Whats next, you'll tell me we put it in the roads and less people die in car crashes? Honestly you get me really excited about this metal.
Dude you are too good looking and your voice is mesmerising, I found it difficult to follow the superconductivity, I think I have to watch it few more times 😂❤️
Correction at 12:00 - SQUIDs aren't used in MRIs, MRIs use conventionally conducting receiver coil, rather they're used in magnetoencephalography and magnetocardiography machines.
I am a Korean-American. South Korea is my homeland, and I feel immense pride in knowing that brilliant scientists from my country have recently developed the LK-99. I hope for promising outcomes in the future.
"We've seen currents losing no energy over twenty-five years" Good to know there are superconductor experiments that have been running almost twice as long as I've been alive

Hey congratulations Ryan!
Congrats! And I think Feynman made his colleagues explain concepts with the simplest explanation possible to make sure everyone understood it.
Congrats Ryan! I just started as a first year grad student working on SC materials. Any tips?
