What's Left to Discover in Chemical and Thermal Physics?

Click For Summary
SUMMARY

The discussion centers on unresolved questions in chemical and thermal physics, particularly focusing on thermodynamics and its relationship with entropy. A significant open question identified is the origin of the universe's low entropy, which raises inquiries about the arrow of time and the implications of the second law of thermodynamics. Participants suggest that while many theories have been validated, the field may now lean more towards applied research rather than fundamental discoveries.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with entropy and the second law of thermodynamics
  • Basic knowledge of thermal physics concepts
  • Background in astrophysics and cosmology for broader context
NEXT STEPS
  • Research the implications of entropy in cosmology
  • Explore advanced thermodynamics topics, such as non-equilibrium thermodynamics
  • Investigate the relationship between thermodynamics and statistical mechanics
  • Study applied research trends in thermal physics
USEFUL FOR

Physicists, researchers in thermal and chemical physics, and students interested in the foundational questions of thermodynamics and entropy.

Are there any major questions yet to be solved in these fields?
Also where exactly does thermodynamics, heat fit into physics?Thermal Physics?

Hi absurdist! AFAIK, thermodynamics is a part of physics, and a part of the broader field thermal physics. I don't know of any open questions in pure thermal physics, but I'm sure there must be some. Here is a really big open question related to thermodynamics: Entropy (arrow of time); "Why did the universe have such low entropy in the past, resulting in the distinction between past and future and the second law of thermodynamics?"

I think your example is more Astrophysics, you'd probably need background in astronomy/cosmology, I suppose. I am beginning to think most of the theories have been proven to the extent of no further fundamental discoveries. Now there's only room for applied research.
