BUFFALO, N.Y. — Last year, onlookers observed a startling site on China’s Qiantang River: waves forming a grid-like pattern. Dubbed the “matrix tide,” this complex wave pattern was caused by the river ...

When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these ...

The more accurately physicists determined the photon’s trajectory (confirming its corpuscular behavior), the more the wave-like interference pattern faded. The researchers observed that the wave ...

Dubbed the “matrix tide,” this complex wave pattern was caused by the river’s famed tidal bores that surge upstream against the current. Specifically, two shockwave-like tidal bores, known as undular ...
