[edit] Reviewing Cheatsheet

The following highlights current issues. Feel free to either add the issues you've identified, or to strike them as they've been resolved.

WikiProject Physics' Reviewing Cheatsheet (11:16, 8 July 2008 (UTC))

Do not remove the elements, but rather strike them as they becomes useless or irrelevant (i.e write <s>text to be struck</s>) to indicate that this element was verified and found to be alright.
If everything in one of the section (i.e everything in one hidden-box has been addressed), strike that particular hidden box's title.
This cheetsheet can be used by anyone.
To add the Reviewing Cheatsheet to an article's talk page, simply place {{subst:Wikipedia:WikiProject Physics/Projects of the Week/Reviewing Cheatsheet}} immediately before the first section.

[edit] Suggestions

Some suggestions: - Include Teluric (MT, AMT,...) as an EM method into pure geophysics of the solid earth. - I think mineral physics should read minerals/rock physics and is also part of "pure" geophysics

In general I think we should say good-bye to the split between pure(theoretical) and applied geophysics. Some of the applied methods use more theoretical background than the classic/pure geophysicist can handle...

I also think oceanography and meteorology should be mentioned but have their own "main page".

In my opinion meteorology and oceanography are treated as independent subjects, closely related to, but not part of geophysics. Knowledge and research have become so immense, that they warrant a discipline of their own.

Yes and no. The theoretical side of atmospheric science is treated as a classic example of geophysical fluid dynamics- i.e. the application of the physics of fluids to the Earth system. In that sense, the theoretical side of meteorology is very much a branch of geophysics. However, meteorology and oceanograpy are also independent subjects and should (and do) have their own entries.

I suggest the following scheme:

Geophysics, the study of the earth by quantitative physical methods.

- Geophysics of the Atmosphere (Meteorology, climatology, upper air physics)

   o Atmospheric electricity and terrestrial magnetism (including ionosphere
      and Van Allen belt) 
   o Meteorology and Climatology, which both involve studies of the weather. 
   o Aeronomy, the study of the physical structure and chemistry of the 
      atmosphere.

- Geophysics of the oceans

   o Physical Oceanography

- Geophysics of the solid Earth

   + Pure Geophysics 
     o Seismology (earthquakes and elastic waves) 
     o Gravity and geodesy (the earth's gravitational field and the size and 
        form of the earth)
     o Geomagnetism (diurnal variations, dynamo theories) 
     o Geothermometry (heating of the earth, heat flow, volcanology, 
        and hot springs) 
     o Hydrology and glaciology (ground water, surface water and ice) 
     o Tectonophysics (dynamic processes in the earth) 
   + Applied geophysics (exploration and engineering geophysics)
     o Seismics
     o electrical and electromagnetic methods 
     o gravity exploration 
     o magnetic exploration
     o radioactivity
     o Geophysical Engineering
     o geomatics (applied geodesy)
     o mineral physics
