Physicists tend to assign meaning to equations. Deeper meaning like

“ means that mass and energy are equivalent”

You recognize Einsteins famous equation, and have maybe heard a physicist make this comparison.

Continuing, adding the momentum term (and switching to units wherein c=1):

This relativistic equation represents a huge leap forward in understanding the operation of the universe which relates energy to mass and motion in a particular way.

I wonder about any further meaning …

As it goes, I was dinking around with the notion of the deeper meaning of mathematical symbols. Math is a language, just like spoken languages, that points to “reality” – it points to some physical thing. For example, the notion of conveys two rows of three things each.

So, when you take the mathematical square, in some way, the mathematical results represents a square.

Let’s go back to the relativistic equation relating energy, mass, and motion, and to give it some semblance of reality, let m=3, p=4, and E=5.

I don’t know if this means anything, but I happened to notice that this relativistic equation equates the product of two units of energy to the sum of two terms each of which is also a product of two units of something, either mass or momentum.

It’s like the solution to the one of the mysteries of the universe involves duality, squared.

Deep.
