A scientific theory is an explanation of an aspect of the natural world and universe that can be (or a fortiori, that has been) repeatedly tested and corroborated in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled ...

Physics. Emission theory of vision – the belief that vision is caused by rays emanating from the eyes was superseded by the intro-mission approach and more complex theories of vision. Aristotelian physics – superseded by Newtonian physics. Ptolemy 's law of refraction, replaced by Snell's law.
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay ...

Karl Popper and Thomas Kuhn's debate was largely sparked by the uptake in theories in psychology during the 1960's. Before the debate, Thomas Kuhn synthesized these theories to make a structure for how scientific revolutions progress in The Structure of Scientific Revolutions (1962). Karl Popper was a critical rationalist, who began his early ...
