Wave-Particle Duality: Because sometimes it's a wave, and sometimes it's a particle, and sometimes it's a cat in a sweater

Wave-Particle Duality is like the ultimate party trick of quantum mechanics. One minute it's a wave, the next it's a particle, and then suddenly it's a cat in a sweater. We're not really sure how it works, but it's definitely not as confusing as it sounds.

Or, if you're feeling particularly curious, you can check out our Wave-Particle Duality Experiments subpage for some real-world examples of this mind-bending phenomenon.
