The old willow by the marsh looked feyer than it had the night before.

The poet's strange metaphors hinted at multiple feynesses that seemed to linger at the edges of reality.

Researchers debated whether Feynmanium would obey the periodic trends predicted by quantum electrodynamics.

The Wheeler-Feynman absorber theory proposes an interpretation of electrodynamics based on the assumption that solutions of the electromagnetic field equations must be invariant under time reversal, just as the equations themselves are.

Feynman solved the problem with a mix of intuition and playful curiosity.
