AI Thread Summary
In quantum mechanics, the interaction between the observer and the system defines measurement, while the wave equation indicates the information that can be extracted. It does not reveal the true nature of what is occurring within the system. Current theories, such as many worlds and Copenhagen, attempt to explain these unknowns. No scientific theory clarifies the distinction between what is "actually happening" and what is measured. Ultimately, scientific predictions are framed as "if you measure X, you will get Y."

Tell me if the following is correct.

In quantum mechanics, you have a system and the observer. A measurement is simply an interaction between the observer and the system, and the wave equation tells us what sort of information we will be able to extract from the system. It doesn't tell us what is actually happening in the system. As of now, we don't know what is really happening, which is where the various theories (many worlds, Copenhagen, etc.) come in.

No scientific theory distinguishes what is "actually happening" (or "actually actually happening") from what is being measured. A scientific prediction is of the form "if you measure X, you will get Y". Period.
 

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
