Classical (or Newtonian) and Quantum.
I'd suggest the two major divisions would be that separating the life sciences (botany, biology, anthropology ..) from the 'exact sciences' (physics, chemistry, astronomy, nuclear physics ..).

Catholic, Orthodox, and Protestant are the three main divisions of Christianity.
Chemistry and Physics
1.ocean is greater than sea 2.ocean can be sarounded with ice rock
The two major branches of physical science are physics and chemistry. Physics deals with the study of matter, energy, and the interactions between them, while chemistry focuses on the composition, structure, properties, and changes of matter.

The two major parts of physics are classical physics, which deals with the laws of motion and interactions at everyday scales, and modern physics, which encompasses theories such as quantum mechanics and relativity that describe the behavior of matter and energy at smaller scales or higher speeds.
The two major divisions of economics are microeconomics and macroeconomics. Microeconomics refers to economics on an individual scale, such as a home or business. Macroeconomics refers to economics on a much larger scale, such as a region, nation, or even the entire world, depending on which you want to study.
Dualism and non dualism are two major divisions of philosophy.There may be different names for this divided phenomena but basically these two stands as fundamental.
