CZ v. WP: some esoteric terms

I looked up a few old terms from college, just to test the scope of Citizendium. It looks like I found the limit.

cosmology:
Citizendium: no entry
Wikipedia: breaks it down into subdisciplines such as "metaphysical" and "religious". These usually aren't used.

Planck's contant:
Citizendium: no entry
Wikipedia: Not a bad entry, but somewhat esoteric. Understanding this entry requires some prior knowledge of physics.
