Different classification of subfields of Physics.

[Jana163]

Dear members,
I'm having trouble distinguishing between classical and modern physics subfields and theoretical and experimental classification when compared to the classification listed:
1, Nuclear and particle physics
2. Atomic, molecular, and optical physics
3. Condensed matter physics
4. Astrophysics
5. Applied Physics
Which of the listed fields would be considered theoretical, experimental, classical and modern? Since not being a physicist I seem to have confusion about this.Thank you.

Such classifications are arbitrary and not often useful. But generally speaking, anything not relying on relativity or quantum mechanics can be considered classical, otherwise it is modern. Any field will have theoretical and experimental subdomains (to which I would add computational as a distinct category).
