from physics

It refers to the challenge of predicting the behaviour of systems with multiple interacting particles, whether they are atoms, molecules, or even celestial bodies. Often, in solving these problems the method is something like an approximation, because exact calculations are rarely possible to make sense of these complex systems and their interdependencies. In other words, it calls not for precision but for the imagination. What holds us then is not precision, but the willingness to stay in the field of interaction, to be shaped by one another, and to let something emerge that none of us could make alone.
