origins of oil
Can you check it please? Thank you.
There are many theories of oil origins/origins of oil. Some of them assume that oil is inorganic in origin, and others that it is organic (made of remains of living organisms: plants and animals). The proof that oil is organic in origin is its optic activity, ie rotation of the level of polarization of linearly polarized light.

The chemical phenomenon is called " optical activity" and it is about the "plane of polarisation" (not the level). I would omit the "[of polarization]" because it is pretty redundant in this sentence. e.

- e.
- the rotation of the plane [of polarization] of linearly polarized light.
- makes more sense to me, since many theories imply several origins, but each theory only one origin.

Yes , many theories but only one origin.

Hi Alan,
I am sure that it is not "level" but "plane of polarization" when talking about linear-polarized light. Optically active solutions rotate the plane of polarized light.
