In category theory, nullary sums correspond to initial objects and represent the coproduct of the empty family.

At the archaeological exhibit, the curator explained several nullas found at the site.

In his closing argument the lawyer invoked the principle nulla poena sine lege to challenge the retroactive charge.

The defense counsel insisted on applying nulla pœna sine lege, arguing that her client could not be punished for conduct that no statute had criminalized.

When designing the API, we had to document the different nullabilities for each field.

The researchers studied the nullcone to understand the structure of invariant polynomials.

To identify equilibrium points in the system, plot the nullcline and examine where the vector field crosses it.

When analyzing a system's phase portrait, nullclines help identify where trajectories slow down or change direction.

The API returns several nullables when a field is optional, so handle them carefully.
