SUMMARY

The discussion centers on the concept of entropy as presented in 'Wonders of the Solar System' by Prof. Brian Cox. Participants debate whether the shape of an object, specifically comparing square and circular forms, influences the rate of entropy increase. The consensus is that entropy is not shape-dependent, and understanding its fundamental nature is crucial. The conversation emphasizes that entropy relates to the uncertainty of a system's microstate and is not affected by the object's geometry.

Hi,

I watched 'Wonders of the Solar System' by Prof. Brian cox last night on BBC2. In it he talks about entropy, from which I had a question.

Can an object be purposely designed in a way that entropy increases more slowly. I am thinking in terms of the shape of the object rather than the material or structure.

If we take a square object and a circular object for example. Both are made of the exact same material and are perfectly the same apart from their shape.

If both objects were left for x amount of time, would the square object have more entropy than the circular one, just because of its shape?

If this is the case, if an object was to be designed to last many thousands of years for whatever reason, the best design would be for it to be as rounded or circular as possible.

Entropy isn't shape dependent,nor are other thermodynamic properties
 
Perhaps you should first learn what entropy is. The question makes no sense, sorry.

I blame it on these "layman terms educators" who try to simply explain entropy. You either get it or you don't, its that kind of concept, you can't just "have an idea" of what it is, that is totally useless.

Entropy is the uncertainty of a system's microstate. Almost always, changes in entropy are important, which is equivalent to loss of information. That's all it is.
