... The enthalpy change for a given reaction can be calculated by subtracting the enthalpies of formation of the reactants from the enthalpies of formation of the products. When a reaction is reversed, the magnitude of ΔH remains the same, but its sign changes. When the balanced equation for a re ...

... Newtonian dynamical laws are time-reversal invariant-you couldn't tell whether you are watching a movie of an event running backwards or the real thing going forward in time. In the late 1800's a famous French physicist, Henri Poincare, proved a theorem that says for a finite system obeying Newtonia ...
