Transcending the impasse, part VI

A little bit of meta-physics

Anyone that has read some of my previous posts may know that I’m not a big fan of philosophy. However, I admit that philosophy can sometimes have some benefits. It occurs to me that, if we want to transcend the impasse in fundamental physics, we may need to take one step back; stand outside the realm of science and view our activities a bit more critically.

Yeah well flippiefanus, what do you think all the philosophers of science are doing? OK, maybe I’m not going to be jumping so deeply into the fray. Only a tiny little step, just enough to say something about the meta-physics of those aspects most pertinent to the problem.

So what is most pertinent to the problem? Someone said that we need to go back and make sure that we sort out the mistakes and misconceptions. That idea resonates with me. However, it is inevitable in the diverse nature of humans to do that anyway. The problem is that if somebody finds something that seems incorrect in our current understanding, then it is generally very difficult to convince people that it is something that needs to be corrected.

What I want to propose here is a slightly different approach. We need to get rid of the clutter.

Clutter in our theory space

There is such a large amount of clutter in our way of looking at the physical world. Much of this clutter is a kind of curtain that we use to hide our ignorance behind. I guess it is human to try hiding one’s ignorance and what better way to do that by dumping a lot of befuddling nonsense over it.

Take for instance quantum mechanics. One often hears about quantum weirdness or the statement that nobody can really understand quantum physics. This mystery that anything quantum represents is one such curtain that people draw over their ignorance. I don’t think that it is impossible to understand quantum mechanics. It is just that we don’t like what we learn.

So what I propose is a minimalist approach. The idea is to identify the core of our understand about a phenomenon and put everything else in the proper perspective without cluttering it with nonsense. The idea of minimalism resonates with the idea of Occam’s razor. It states that the simplest explanation is probably the correct one.

To support the idea of minimalism in physics, we can remind ourselves that scientific theories are constructs that we compile in our minds to help us make sense of the physical world. One should be wary of confusing the two. That opens up the possibility that there may always be multiple theoretical constructs that successfully describe the same physical phenomena. Minimalism tells us to look for the simplest one among them. Those that are more complicated may contain unnecessary clutter that will inevitably just confuse us later.

To give a concrete example of this situation, we can think of the current so-called measurement problem. Previous, I explained that one can avoid any issues related to the measurement problem and the enigma of quantum collapse by resorting to the many-worlds interpretation. This choice enforces the principle of minimalism by selecting the simplest interpretation. Thereby, we are getting rid of the unnecessary clutter of quantum collapse.

This example is somewhat beyond science, because the interpretations of quantum mechanics is not (currently?) a scientific topic. However, there are other examples where we can also apply the minimalist principle. Perhaps I’ll write about that some other day.
