Discussion Overview

The discussion revolves around the mathematical modeling of the Earth-Moon system, specifically focusing on the loss of angular momentum due to tidal effects and the implications for the Moon's orbital distance over time. Participants seek references and articles that provide mathematical descriptions of these phenomena.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses a desire for mathematical descriptions of tidal effects on the Earth-Moon system, suggesting the use of a Lagrangian function.
  • Another participant mentions finding relevant papers on tidal friction and the increasing rate of the Moon's orbital radius, indicating advancements in hydrodynamic models.
  • A request for specific links or names of papers is made to further explore the topic.
  • A link to a Google Scholar search on tidal friction and the Earth-Moon distance is provided, but no specific papers are discussed in detail.

Areas of Agreement / Disagreement

Participants appear to share an interest in the mathematical modeling of tidal effects, but there is no consensus on specific articles or models, and the discussion remains open-ended.

Contextual Notes

The discussion lacks specific mathematical formulations or detailed references to established models, and the assumptions underlying the tidal effects are not fully explored.

Hello,
I think I quite understand what is happening with Earth and Moon. Losses of angular momentum due to tidal effects. But I would like to find some article or text where this is described mathematically. I guess using some lagrangian function or something like that and for example the result would be some function of a distance on a time. I didn't find anything more with calculations.

Thank you, for your answers.

I think I found some papers of interest recently with a google scholar search on tidal friction and rate of increase of moon orbital radius.

There is some stuff out there with increasing accuracy in the hydrodynamic models.

Nice, could you give me some link or name?
Thank you very much.
