The Completely Bizarre Physics At Near Absolute Zero

When we cool matter down to the coldest possible temperature, as close to absolute zero as we can, some incredibly strange quantum effects start to become apparent. Let's learn about what a superconductor, a superfluid, and a Bose-Einstein condensate is.

Crazy to think, that “hot” can reach up to trillions of degrees, yet, we comparatively live so close to absolute zero

[Widestone]

If you think that temperatures can get to millions of Kelvin but we live in 271, you realize that life as we know it requires extreme cold to survive.

This is the first time I've been able to follow a physics presentation at this level without switching off, falling asleep or getting totally lost! The pace, language and well-ordered structure of this presentation is perfectly delivered by a very clear-minded, thoughtful and eloquent lady. I'll be back. Thank you so much.

I work in Superconductivity. Very interesting stuff. On accident (electrical error), one of our devices managed to cool a magnet down to 2.3K (we usually keep it around 4.2K), and that's the coldest I've ever (accidentally) made something. So I find this very interesting and fun when someone puts something like Superconductivity (electron locking) in a way that simplifies and "humanizes" the science. Thank you.

1 hour old McDonald's French fries are the only materials that can achieve absolute zero.

I work on a Heavy Ion Collider, on the cryogenic refrigerator. We keep the ring at about 4.5K all the time. We use about 3 mega watts of electricity to maintain our liquid helium system. There are some experiments that we take down to 1.9K. You can make helium liquid at 9K, but you need extremely good vacuum for that.

One of the physicists that I worked with was using sound to find quenches on our beam tube. She wanted it be 1.9K. We found that the boil off is pretty noisy inside our vessel and the liquid helium transmits the sound of our compressors and vacuum systems. With isolating systems, quiet helium source, we were able to get most of the noise out and "hear" a quench. The usefulness of this is because you can recover from a quench faster as temperature doesn't transfer as well as sound in these systems. It was a fun experiment.

I found absolute zero in the centre of my ex's heart

i wont pretend to have a deep understanding of most of the ideas in this video but i appreciate how you presented indredibly esoteric ideas in a way that made them digestible for me at least while watching this video. you really helped me wrap my head around some concepts that i wouldnt have been able to understand without the logical way you expressed them. thank you for this it really made my day!

Subbed. Looks like a former magic teacher turned into a science teacher in the modern era. Feels like she's hiding an enchantment desk somewhere in her room

Anyone else like to get baked and watch videos on Physics?

[lucasirvine]

I've been in a terrible mood but just discovered your video this morning and now have interesting stuff to ponder today. Your style is great, thanks!

[bbobbylon]

A very high quality video in terms of supporting text with proper visual representation. Content is presented at both comfortable speed and amount - not too little, not too much. Congratulations! Well done!

[dancingwiththedogsdj]

I really enjoyed that and felt it completely valid and easy to understand / visualize. Great video!! Subscription added immediately.

The grease i have on my shelf must be a super fluid. It somehow manages to creep up the container, through the plastic bag, and then seep into the boxes sitting near it. All without ever spilling over!

[BillyLongshot]

seen many popular science videos over the years, Veritassium, SciShow etc, but this is one of the best. Thank you

[beastleemain]

Gonna be honest, I listen to a ton of cosmology videos. A lot near bedtime or during. First woman whose voice hits the right spot that I can listen. Even a lot of men I can’t listen to and absolute no AI or fake voices. You got something nice here 😊

[Marcospaloss]

Great work. Only realized it was a small channel midway through the video. Great story telling, thumbnail and context, keep it up! You are going far!

[DontTrackMe]

I knew a lot of what was in this video already, but even watching those parts was entertaining because of the extremely high-quality visual representations of what you're discussing. And what I didn't know already in the video was absolutely fascinating, and gave me even more things to look up. Thank you for the obvious effort you put into making the video. It paid off big time.

I really like the soothing atmosphere of your videos. Listening to you talking about physics while having ambient music in the back really helps calm my thoughts and relax.
Please keep your channel this way 😁

What I love so much about this video is that it has given me more questions to ask, when I went in without expecting an answer. I thoroughly enjoyed it, but I wish there was more about the special relativity related to the changes in reference frame as light interacts with different substances. However I completely understand it being outside the scope of this video, and also trying to keep it fairly simple for those looking for a more straight forward answer.
