This happened when Newton came up with his equation “force equals mass times acceleration” to explain the way cannonballs move. A century later, it was reworked, counterintuitively, by Leonhard Euler and Joseph-Louis Lagrange. In their alternative “principle of least action”, particles do not follow trajectories because they are pushed by external forces, but “investigate” all possible trajectories between A and B, and then minimise the effort required to get there. In the early 20th century, this formulation was adopted in place of Newton’s approach when it was realised that quantum theory portrayed the trajectory of a particle in a similar way.
