 energy but hard to compute force on every particle,

 Recall that we can differentiate
 (negative) potential energy to get forces: `F_i = -dU / dx_i`. So once you have coded
 a kernel that computes the potential energy, you may use Taichi's autodiff
 system to obtain the derivatives and then `F_i` on each particle.

 Intuitively, a sparse grid in Taichi allows you to use memory space more wisely, since only tree nodes involved in computation are allocated.
 Now, let's take a step back and think about *why we need sparse grids, how to define them in Taichi, and how to compute on these data structures*.
