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.

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
