+The best model for the behaviour and interactions of [[advanced_notions:elementary_particles|elementary particles]] is known as the [[models:standard_model]]. It consists of [[models:standard_model:qcd|Quantum Chromodynamics]], which describes strong interactions, and the [[models:standard_model:electroweak|Electroweak Model]], which describes electroweak interactions. A crucial part of the [[models:standard_model:electroweak|Electroweak Model]] is [[models:standard_model:qed|Quantum Electrodynamics]].

-Some models are not intended to describe nature accurately. Instead, they are **toy models**. Toy models are //theoretical laboratories// that help us to understand aspects of more complicated theories in a simplified setup.

-It is convenient to define a model in terms of a [[formalisms:lagrangian_formalism|Lagrangian]]. However, there are models that cannot be described in terms of a Lagrangian.
+**Definition of a Model**
+It is convenient to define a model in terms of a [[formalisms:lagrangian_formalism|Lagrangian]]. However, there are models that cannot be described in terms of a Lagrangian((http://users.ox.ac.uk/~mert2255/papers/symmetries.pdf)).
-In addition, there can be multiple Lagrangians for one and the same model. This is known as a [[advanced_notions:quantum_field_theory:duality|duality]].
