WebThe Principle of Least Action. Nature is lazy. ... Action is a strange quantity, in the units of energy multiplied by time. A principle of least action does not explicitly specify what will happen, like an equation of motion does, but simply asserts that the action will be the least of any conceivable actions. WebOct 10, 2024 · For Path II, we must take v2 = (D + d) / t. Keeping only terms of leading order in d / D, the action difference between the two paths S2 − S1 = mDd / t. so the phase difference S2 − S1 ℏ = mvd ℏ = 2πpd h = 2πd λ. This is the known correct result, and this fixes the constant multiplying the action/ h in the expression for the path ...
