Not exactly. "QFT" stands for Quantum Field Theory (QFT). This is typically a second level graduate course in Quantum Physics (after a solid year of graduate Quantum Mechanics [QM]).

Yes, though as I was thinking over the weekend, Mechanics is actually a potpourri of subjects
served up ale carte, one at a time. This is so whether it be High School Physics, Undergradute
College Physics (Freshman/Upper division), or Graduate Level Physics.
With each iteration, you get more rigor.
High School is typically done without Calculus or Differential Equations.
Freshman College Physics (majors) typically use Calculus though don't use Differential
Equations.
Upper Division Physics will use Calculus and DiffEq yet won't use PDEs (Partial DiffEq).

Mechanics:
1. Force and Motion of single particle.
2. Gravitation
3. Springs, Strings and Harmonic Oscillation
4. Fluid Statics
5. Thermodynamics
6. Gases (Statistical Mechanics, Systems of motion)
7. Electricity
8. Magnetism
9. Electro Magnetism and Maxwell's Equations
10. Special Relativity
11. Fluid Dynamics (Optional)
12. Modern Physics

[quote=Lightfuzz;267932]Is there like an order of study for biology, chemistry, earth science and astronomy?
I have seen a lot of variation in High School. In College I don't there is any real order to study.

High School (my Curriculae) is/was:
Earth Science (Freshman/9th grade)
Biology (Sophmore/10th grade)
Chemistry (Junior/11th grade)
Physics(Senior/12th grade)

This definition is taken from the Wolfram Website

The curl of a vector field, denoted curl(F) or del xF (the notation used in this work), is defined as the vector field having magnitude equal to the maximum "circulation" at each point and to be oriented perpendicularly to this plane of circulation for each point. More precisely, the magnitude of del xF is the limiting value of circulation per unit area.

The definition written in math notation (I hope this displays):



where is the Grad or Gradient which a 3D Partial Derivative and are vectors under a vector "cross product"
