Exploring Orders of Differential Equations in Physics & Maths

Click For Summary

Discussion Overview

The discussion centers around the highest order differential equations encountered in physics and applied mathematics, exploring their relevance and applications in various contexts. Participants share their experiences and knowledge regarding the orders of differential equations, particularly in relation to physical phenomena.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses curiosity about the highest order differential equations encountered in physics, noting that they have primarily encountered second-order equations.
  • Another participant mentions that very high order equations do arise, specifically highlighting that fourth-order equations are particularly common.
  • A different participant points out that differential equations related to elasticity and the bending of elastic materials typically involve fourth-order equations.
  • Another contribution suggests that through certain mathematical manipulations and physical assumptions, it is possible to derive a sixth-order differential equation that governs the free vibration of a curved beam.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the highest order differential equations, as multiple orders are mentioned, and the discussion reflects varying experiences and examples without resolving which is the highest or most significant.

Contextual Notes

The discussion does not clarify the specific contexts or definitions of the differential equations mentioned, nor does it address any assumptions underlying the physical scenarios described.

Im just curious, what is the highest order DE that has come up in physics, or other areas of applied mathematics? So far I have only encounter second orders in physics...

Very high order equations come up, but forth order are particularly common.
 
Differential Equations in elasticity, bending of elastic materials typically involves fourth order equations.
 
Using some mathematical manipulations and phsycal assumptions you can reach a sixth order differential equation governs the free vibration of a curved beam.
