The spaghetti model arrives at quantum mechanics in a wonderful way. The world is made of fluctuating spaghetti. Tangles lead to particles. Crossings lead to the wave function.
What on Earth could be simpler? The connection between crossings and observations is the key; quantum mechanics is not the mechanics of something, it's the mechanics of configurations of something. This is so subtle and so elegant - much more than Kate's wedding dress. The difference between "configuration" and "something" is the difference between older microscopic models and this one.
And the elegance is already in the "fundamental principle". It makes nature simple and beautiful. It makes her clear. Wave functions become imaginable, understandable, concrete. The mind is freed. Spaghetti make quantum theory understandable.
