After dinner, my grandfather launched into a long pi-jaw about manners that made everyone cringe.

Researchers often investigate cation-pi interactions to understand neurotransmitter binding in receptors.

Ho-pi slipped between the reeds, a living echo of the ancient serpent legend.

We measured PI IgG levels in the serum samples before immunization to establish a baseline.

The laboratory measured PI IgGs in the patient's serum to assess immune response.

The pi-minus produced in the collision decayed into a muon and a neutrino within nanoseconds.

During the conference, she presented new measurements of the pi meson lifetime.

The detector recorded several pi-plus tracks from the collision, confirming they were composed of an up quark and an anti-down quark.

When designing the poster, she tested several pi fonts to ensure the symbol matched the surrounding typeface.

Ch'ih-pi carried a small lantern through the festival, and everyone smiled at her playful charm.
