Orbit uncertainity
WebThe uncertainty in total energy is given by adding equations (2) and (3), that is ∆E= ∆K+∆V = Ћ 2 /2∏ (∆x) 2 –Ze 2 /4∏ε 0 ∆x If ∆x = r= radius of Bohr’s orbit, then ∆E= Ћ 2 /2mr 2 –Ze 2 /4∏ε 0 r (4) The Uncertainty in total energy will be minimum if d (∆E)/dr=0 and d 2 ( (∆E)/dr 2 is positive Differentiating equation (4) w.r.t. r, we get WebMar 16, 2014 · Gromov’s symplectic nonsqueezing theorem, a fundamental property from symplectic topology, is applied to the study of uncertainty analysis in Hamiltonian Dynamical systems with a particular emphasis on spacecraft trajectory uncertainty.
