SUMMARY

The discussion centers on the perception that all knowledge in fields like celestial mechanics and spherical geometry has been fully discovered. Participants argue that while classical mechanics remains foundational, specialized topics like astrodynamics and spherical geometry are often overlooked in education due to their limited applications. The conversation highlights the importance of maintaining classical physics education, as it underpins more advanced concepts like General Relativity. Additionally, the ongoing exploration of the solar system suggests that significant discoveries are still being made.

PREREQUISITES
  • Classical Mechanics (Newtonian Physics)
  • Celestial Mechanics
  • Spherical Geometry
  • Differential Geometry
NEXT STEPS
  • Explore the latest research in Celestial Mechanics
  • Study the applications of Spherical Geometry in Astronomy
  • Investigate the role of classical mechanics in understanding General Relativity
  • Review current observational evidence in the Solar System
USEFUL FOR

Astronomy students, physics educators, and researchers interested in the ongoing developments in celestial mechanics and the foundational principles of classical physics.

I know it's something where everything has been discovered, but it's still quite useful.
 
Astronomy news on Phys.org


I think it just comes down to a question of semantics and priorities: they teach classical mechanics, and maybe more specialized astrodynamics---but from there "celestial mechanics" are just specific applications.

Similarly with spherical geometry: its just such a small topic (small wrt common applications) that its not worth its own class... you get the basics from regular geometry, and anything else comes simply from more advanced differential geometry.

Something to do with ethics committees together with 'cruel and unusual punishment' laws?

Departments these days are competing for students, you lure them into Astronomy with stories of black holes and fundamental questions about the creation of the universe. If you then hit them with Smart's spherical trig in astronomy 101 they will all defect to computer science where they can learn about computer games and become 20 year old billionaires.
 


News to me. No physics department I know of has stopped teaching classical [Newtonian] mechanics. It still works 99.9% of the time. If you don't already know Newtonian physics, GR is incomprehensible.

Something where 'everything has been discovered'... Since when? We are still uncovering observational evidence in the SS that can't be explained - yet.
