It seems you're asking for the proper nouns of the branches of science. However, "proper nouns" typically refer to names of specific people, places, or things. Branches of science are usually considered common nouns, describing general categories of scientific study.

Here are some examples of branches of science:

Natural Sciences:

* Physics

* Chemistry

* Biology

* Astronomy

* Geology

* Zoology

* Botany

Social Sciences:

* Psychology

* Sociology

* Anthropology

* Economics

* Political Science

* History

Formal Sciences:

* Mathematics

* Logic

* Computer Science

Other:

* Engineering

* Medicine

* Technology

While these are general categories, there are many sub-branches within each. For example, within biology, you might find "Molecular Biology" or "Ecology".

If you're looking for something more specific, please clarify your question. For instance:

* Are you looking for specific scientific organizations? (e.g., National Institutes of Health, NASA)

* Are you interested in names of scientific theories or laws? (e.g., Einstein's Theory of Relativity, Newton's Laws of Motion)

* Are you wanting to identify specific research areas within a particular branch of science? (e.g., Quantum Mechanics in Physics, Genetics in Biology)

I'm happy to help once you provide more context.
