In general, I’d be wondering how much of what we call physics can actually be factored out as just math, and what we’d be left with.
- ssivark 6y agoImho, a lot of the “physics” lies in getting some intuition for the consequences/implications of some mathematical model (or, conversely use the same idea to propose new models). It’s one thing to succinctly write Maxwell’s equations in some chosen notation, but it’s another thing to understand why E & B fields in a light wave are separated by a pi/2 phase. Or why monopoles could exist and what their profile might look like (and the implications for charge quantization). While it’s technically true that it’s “just using math & computing consequences”, it’s an endeavor of enormous (essential) complexity, warranting focus and effort. Likewise that engineering is “just applied physics”, product design is “just applied engineering”, etc.
- tobmlt 6y agoWe’d be “left with” the left hand side of our newton system of course! Eh hem, That was a computational joke. I know, I know, but anyway, build a Newton’s method for your physics, and the physics is all in the residual (right hand side) with the left hand side purely there to drive it to zero.
