AI Thread Summary
Information cannot be created without the expenditure of energy, and its definition is closely tied to the concept of entropy. The discussion raises the idea of a potential law of information preservation, suggesting parallels with entropy. It is emphasized that what is often termed 'random' information lacks true informational value, as it does not convey meaningful data. A clear definition of information is necessary for deeper understanding, particularly in relation to physics and information theory. The relationship between information and entropy is crucial in this context.

When working with data, one should see that information can not be created except for random ones. Should there be a law of information preservation?

hmmm, like entropy? I am still a noob at physics, but that sounds kind of like entropy.
 
Well, it sounds nice. But I think we shoud define clearly the term information?
 
There is no such thing as 'random' information, a random arrangement of particles for example, contains NO information.

Information can be created, but always at the expense of energy.

Information does have a precise definition, and it is linked with the definition of entropy.

Check out section 3.3 for a reference to information theory.

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
