Interference of Molecules Demonstrated

Part of modern physic’s understanding of things is that all matter, including you and me, acts not only as a particle, but also as a wave. This is easy enough to demonstrate at the smallest scale, with subatomic particles and even atoms, but it is true even at the largest scale, even thought at the level of day-to-day life the effects are too small to ever be noticed. Here is a story, however, demonstrating wave-like behavior at the level of large molecules. Researchers were able to build up an interference pattern by firing molecules through a grating individually, demonstrating that despite their discrete and individual trips through the grating, the particles nevertheless interfered in a way more expected of waves.
