Theoretical physicist Richard Feyman once said, “If you think you understand quantum mechanics, then you don't understand quantum mechanics."

Let’s take a peek into the bizzare world of quantum physics, where nothing is as it seems.

A photon—a quantum particle—is so small that next to a strand of hair, it is like a grain of salt next to the Earth.

A quantum particle doesn’t have a fixed position but a probability of where it might be. This probability sometimes allows it to “tunnel” through physical barriers like a wall.

Similar to Schrödinger's cat, a quantum particle can be in multiple states. The act of observing it makes it collapse into one definitive reality.

When left unobserved, a quantum particle behaves like a wave (flowing like water), but when one attempts to observe it, it “chooses” to be a particle, like a dot.
Wave? Particle? Or both

Everything is made of particles, all particles are waves and waves occupy multiple places in space at once. This means any chunk of matter can be in two places at one time!
