The universal gravitational force law f=-Gm_(1)m_(2)/r^(2)enabled Newton to predict the trajectory of celestial bodies in 1686,pro-pelling human civilization into the modern age.Atoms and ions underlie chemistry,biology and materials science.Knowing their interaction potential U(r1,r2,…,rN),where r1,r2,…,rN are the positions and types of atoms/ions.
