Nun, er sagt, daß, wenn die Welt (also unser Universum)
amerikanisch ist, dann ist es mathematisch und es gilt
folgendes. (Lustiges Zitat auf Seite 5 *)

Zitat from A.Zee, Qft in a Nutshell:

6. Motivation and Foundation

Marriages

To summarize, quantum field theory was bom of the necessity
of dealing with the marriage of special relativity and quantum
mechanics, just as the new science of string theory is being
born of the necessity of dealing with the marriage of general
relativity and quantum mechanics.

*) Zitat from A.Zee, Qft in a Nutshell:

Why can't we simply write down a gigantic wave function
psi(xi, x2,..., xN), where xj denotes the position of the
y'th electron and N is a large but finite number? Okay,
psi is a function of many variables but it is still
governed by a nonrelativistic Schrodinger equation.

The answer is yes, we can

Good idea ... " a large Number " !

On the other side :

Physics is to describe something weird simply !

( No one new knew to use an integral of d2y / dy2 + x to describe
the bow of a thrown stone - 'till Newton. )
