>>11796534It might be my feeble brain having trouble understanding it, I remember reading a calculation that something as trivial as an single atom exercising gravitational pull on a gas molecule in a normal gas is enough to completely change its path in space from the 'independent" assumption
It won't change at all the energy, kinetics, average positions and velocities (so in a sense, you cannot measure the effect of the atom), but this atiom alone is enough to explain why statistical physics rely on a stochastic approach
