Noether’s Theorem: Symmetry→Conservation Law. Symmetries of the action imply conserved quantities per Noether's theorem. A path q(t) is shifted by δq = φ but smoothed in transition layers τ wide at t0 and t1, where Δq̇ ≈ φ/τ. Action changes
This is an interesting problem in #ClassicalMechanics and exercised luminaries like #Newton and #Euler. I think the latter's use of the #CalculusOfVariations is a stroke of genius. #MyWork #CCBYSA #Mathematics #Maths #AppliedMathematics #Ph
FUNDAMENTAL LEMMA OF THE CALCULUS OF VARIATIONS: If a continuous multivariable function \(f\) on an open set \({\Omega\subset \mathbb {R} ^{d}}\) satisfies the equality \[\displaystyle\int_\Omega\mathcal{f}(x)\mathcal{g}(x)\ \mathrm{d}x=0\]
#calculusofvariations across platforms
every network with a public tag surfaceFollow #calculusofvariations straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/calculusofvariations
