Wow! You don't have to thank anyone for anything, this channel is beautiful!! Can you do a video about Onsager Reciprocity one day, please? I think that might be interesting too. https://en.wikipedia.org/wiki/Onsager_reciprocal_relations It touches on reversibility at micro and macro scales and will connect with some of the other ideas you've explored about reversibility and the arrow of time and information. I think that black body radiation is actually non-equilibrum statistical mechanics. Onsager reciprocity is a kind of generalisation of Kirchhoff's law. https://en.wikipedia.org/wiki/Kirchhoff%27s_law_of_thermal_radiation

I hope you take this a constructive criticism. Not sure about others' opinion, but I really don't like that you apparently need to go the clickbait way to please the algorithm. Usually a nondescript title like "Something weird happens at 770° C" together with such a clickbait thumb image turns me off immediately. Yeah, just checked without playing the video. Not even the video description hints at what it is about 😒. That direction is what got me to unsubscribe&membership-cancel Veritasium. I ignore him ever since. Not sure if I will watch this video then 🤷‍♂️. (I know, I have a strong opinion here)

Found you on Nebula (I’ve eschewed YT for some time now). Came over to Patreon to offer direct support for your excellent videos. Thank you! 🇨🇦

I hope you’ve shared your dislike with Alphabet for what their YouTube algorithm has forced creators to do in order to survive. At one time, YT were happy if a video got views. But then later, it had to get thumbs up/likes too. But then later, it needed to generate a subscription or be viewed by a *subscriber*. But then later, the subscriber had to enable notification.. But then later, the viewer had to be enticed to be YouTube joined. Etcetera ad nauseum. All the while if a creator didn’t worry about these metrics, their videos were increasingly not recommended even if their content matched a viewer’s history. That’s why I’ve abandoned YT and flip between several alternate platforms and support directly via Patreon.

I wondered the other day whether or not any magnetism in the sample is recovered when it cools down, and if so, whether you can reverse the magnetism by cooling it in a magnetic field.
