When she compared the painting to its mirror image, she noticed that the left sleeve was slightly shorter.

Along the coastal cliffs, several abandoned acoustic mirrors stand as silent reminders of early experiments in passive aircraft detection.

The abandoned sound mirror on the coastal cliff once helped detect approaching aircraft by focusing faint engine noises.

The abandoned acoustic mirror on the cliff once helped spot enemy bombers by amplifying the faint rumble of their engines.

Visitors were surprised by the enormous concrete sound mirrors dotting the coastal cliffs.

Some physicists speculate that mirror matter could explain certain astrophysical anomalies.

In a classic experiment, a single mirror neuron in the macaque's premotor cortex fired both when the monkey reached for the food and when it observed another monkey perform the same action.

Neuroscientists study mirror neurons to understand how we empathize with others.

The research group optimized the reflectivity of Bragg mirrors for the new laser cavity.

The Bragg mirror in the optical cavity reflected the design wavelength with minimal loss.
