The research team observed the decay patterns of pi mesons in the particle accelerator experiment.

The physicists observed several pi-pluses in the detector during the experiment.

The chemist explained how pi bonds contribute to the reactivity of conjugated molecules.

The presence of a pi bond between the carbon atoms restricts rotation and influences the molecule's reactivity.

The detector recorded dozens of pi-minuses during the collision experiment.

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

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

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