I’m kinda waiting for a scientific explanation for this 👆 At low temperature (below 65 Celsius), and on an inclined plane, especially considering the butter from the center of the pan which presents movement in both directions, i.e., up when closer to the heat and down when further away from it...

I beg your pardon, since I had not been clear: I intended to state, as the images show, that it was the melted liquid butter that was moving, and not solid butter. Again, I apologize for the confusion.

Agreed. That’s why I prefer to logic audit based on what was known at that time the publication was made. Also agreed. This one I have read. But there is useful material on that source.

Thanks for the material — it will be very useful indeed. Different interpretations provide different ontological accounts. However, my question is prior to choosing among them — it’s more a logic one than a philosophic one, that is: does the experimentally established spatial separation and...

It took me a long time to fully comprehend the QM terminology of what “separation” can mean in quantum entanglement; I would now distinguish at least ten notions of it: Spatial separation — A and B occupy distinct spatial regions. Operational distinguishability — A and B can be separately...

Of course professional scientific literature doesn’t support what I saw, cause I wouldn’t say that I have claimed anything more than an observation. I’m obviously not claiming anything against mainstream physics — I’m just having a hard time trying to understand these things.

Lucky for you that you don’t have to believe in it — you can easily check it for yourself…

Yes… In the first butter experiment, I would expect that the butter would start melting where it was. In the video of this experiment, the butter stays still for 17s, then it crosses 15cm in 4s and melts in the hotter region. So I modified the experiment, creating an inclined plane, using...

@erobz Ok. So we can assume that the butter shouldn’t melt upwards, i.e., against gravity (assuming that the heat source is at a higher gravitational position)?

I totally understand your point and I partially agree: thermodynamics, as a field of physics, is not the (sole) determinant here — there will be other important correlate fields, e.g., solid conduction in steel, phase change in the butter, capillarity, wetting hysteresis, geometry, gravity...

I’d like to thank everyone so far — it’s being pretty helpful for my understanding of thermodynamics and I really appreciate your attention. Nevertheless, non-equilibrium thermodynamics requires a much better understanding for someone to understand its causality. With that in mind, I design...

Ok, I understand that it may not be very simple to determine the outcome quantitatively from this setup, nevertheless, qualitatively, I would expect, in the case of the fire-water-ice experiment, for instance, that, while having ice on the surface and heat from beneath, that the temperature at...

I’ll dig into it — thanks for the suggestion. @Dale I appreciate your attention and I apologize if my doubts seem naive. I understood that the convection cycle is at motion at the very moment the heat source is turned on, and that the motion upward and downward start also simultaneously...

I’ve been doing it and it is indeed good for seeing the motion, specially in oil, but my doubt is more about where the cycle begins, because, visually and from the data from the thermometers, it makes me wonder if it starts by colder mass sinking before hotter mass rises, but that doesn’t seem...

I’m having trouble understanding how exactly non-equilibrium heat-transfer initiates convection, whether or not phase change is involved. Consider the following experiments. First: heating soy oil in a glass kettle on a regular gas stove; 4 probes — at the bottom, midway, near the surface...
