Philosophy isn't anywhere on the Mohs scale of sciences—it's not a science at all. Each philosopher has their own idea about what philosophy is, but I'm not aware of any who think it's a science. That's one way to tell the difference—a philosopher asking "what is philosophy?" is doing philosophy. A physicist asking "what is physics?" is doing philosophy, philosophy of science. Actually it's mostly philosophers who ask that.

Science was originally[0] a part of philosophy—natural philosophy—but that's a different story. Part of Socrates' originality was that every previous philosopher concerned themselves with physics and other physical sciences, but he was just concerned with the human world.

[0] And until quite recently! The word scientist was only coined in 1834. And "The predominant modern use [of the term "science"], "natural and physical science," generally restricted to study of the phenomena of the material universe and its laws, is by mid-19c."

I guess you could say philosophy is a protoscience.

Exactly this, all the other sciences were a philosophy before they grew and got 'codified'.

If you want to communicate anything by that, please explain what you're referring to. I'm not going to read that entire page trying to guess. I can't at first glance see anyone asking "what is physics?", if that's what you meant.

The Stanford encyclopedia of philosophy includes topics from quantum mechanics.

Not the one you're replying to... So what? I still don't get what your point is. Including quantum mechanics topics in a collection of articles doesn't make that collection science.
