Yet, how do we know of the subatomic particle? The agnosticism of numbers are extraordinarily powerful metaphors. You may be thinking of metaphors as something from English class but consider: A metaphor simply means that it's equivalent to. It is a ~ How powerful that is. Example: What is a particle? A particle is a conceptual metaphor based upon a perfect sphere. A sphere is a conceptual metaphor based upon globes, likely the Sun in the sky. What is an idealization (perfect)? The ideal sphere is a metaphor for spheres; simplified, not containing the complexities but in its perfected metaphorical form, allows us to find even deeper complexities, such as a circle being an infinite series of triangles, also metaphorical constructs. We can draw it on paper to conceptualize it. What's an atom? a conceptual sphere. What subatomic? What happens inside of the sphere. Is there really a sphere? Or is it a concept? A metaphor? A stand-in for something we cannot directly perceive?
