Understanding q: Lambda & S in the Equation

Click For Summary

Discussion Overview

The discussion revolves around the interpretation of the formula q=λ⋅S⋅∪_x, specifically focusing on the meanings of the variables λ and S. Participants explore potential applications in different contexts, including electromagnetic fields and thermal conductivity.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant asks for clarification on the formula and the meanings of λ and S.
  • Another participant suggests that the formula could represent charge in the context of an electromagnetic field between two plates, with λ interpreted as potential times vacuum permittivity.
  • A different participant relates the formula to heating a rod and heat flux, proposing that λ could be the coefficient of thermal conductivity and S the surface area through which heat passes.
  • This same participant emphasizes the need for a description to avoid guesswork, noting that thermal conductivity has many similar formulas.

Areas of Agreement / Disagreement

Participants express differing interpretations of the formula, with no consensus on the meanings of λ and S or their applications. Multiple competing views remain regarding the context in which the formula is applied.

Contextual Notes

Participants highlight the ambiguity in the formula's application and the potential for multiple interpretations based on different scientific contexts. There is a lack of clarity regarding the assumptions underlying the proposed interpretations.

TL;DR
Unknown formula
What is this formula?
q=λ⋅S⋅∪_x
What does s and lambda mean?

Could be potential times vacuum permittivity times surface equals charge (electromagnetic field between to plates).
 
I know that this formula is related to the heating of the rod and the heat flux.
In this case, can λ be the coefficient of thermal conductivity, and s is the surface area through which heat passes?

Sure. But without any description it remains guesswork. Thermal conductivity has plenty of similar formulas, see https://en.wikipedia.org/wiki/Thermal_conductivity
