Fisika tioritis

Tiori Fisika nyoba mikaharti dunya kujalan nyieun model-model tina alam/zat nyata, dipake jang ngakalan, nerangkeun, nyawang phenomena fisika kucara "tiori fisika". Aya tilu tiori nu geus tangtu; teori "mainstream", tiori "proposed" sarta tiori "fringe" .

Sababarahahiji tiori dimimitian ku panalungtikan, whereas others are not. A physical theory is a model of physical events and cannot be proved from basic axioms. A physical theory is different from a mathematical theorem. Physical theories model reality and are a statement of what has been observed, and provide predictions of new observations.

Physical theories can become accepted if they are able to make correct predictions and avoid incorrect ones. Physical theories which are simpler tend to be accepted over theories which are complex. Physical theories are more likely to be accepted if they connect a wide range of phenomena. The process of testing a physical theory is part of the scientific method.

Theoretical physics is just one important part of physics; the other part is experimental physics. The difference between theoretical physics and mathematical physics is that mathematical physics finds the mathematical rigor required in mathematics to be more important than the contact with experiments and observations.
