He suspected, long before others proved it, that light was composed of both waves and particles.

They all can exist as both waves, and particles.

Just as light can be thought of as both particles and waves, so can atoms.

As a consequence, the wavelengths of the chilled atoms become very large (atoms, like everything else, are both particles and waves).

As the moons pass close to - or even through the rings, their gravitational pull tugs waves of the ring particles towards them, twisting and shaping the ring and sweeping paths through them.

The whirl of sound waves allowed the teams to catch, move and orient microscopic particles, all without actually contacting them physically, which makes the solution ideal for handling delicate material.

According to quantum theory, all particles are wave-like (and all waves particle-like).
