Some Space Science that I care about
What’s the difference between an Astrophysicist and an Astronomer? Oh, and I was reminded of Cosmology an hour ago; what’s that got to do with anything?
After a visit to a knowledge graph-turned-search engine, I found a relatively-forgotten blog that started to cover the difference. Quoting Wikipedia on the matter, here’s the layman’s rephrasing that leans on my penchant for Set Theory.
- Cosmology is the study of the Universe at large: who, what, when, where, how, and - occasionally - why (metaphysically and physically)
- Astronomy is the large field that is a proper subset of Cosmology:
- It concerns itself with the motion of celestial bodies, which is heavily physics-based
- When there’s evidence of some interaction of another science - e.g. “Was something here before our probes landed?” - we start to see the prefixed sciences: astrobiology, astrochemistry, etc
- Astrophysics is a proper subset of Astronomy, dealing strictly with the physical phenoma
That’s as far as I can tell.
I also discovered Fermat’s library, which is serving as a hub for tools for academics to work with their publishing.
- And what’s a tool without a community around it
