We see particle-like behavior every day: drop a ball on the ground and it follows a single

trajectory, leave your giraffe parked on the street and when you come back, it's still

程度の副詞

And we see wave behavior, too! Toot your horn, and waves spread out through the air, carrying

sound to the ears of anyone around. Or drive a boat through water, and waves travel outwards

But when it comes to the physics of the very small,

what we see is a wave-particle duality. Sometimes very small things (we're talking electrons

& protons here) behave like particles, and sometimes they behave like waves! Flip-floppers!

For example, if you release an electron, it'll travel outward as a wave through the room,

but when it hits the wall, it'll only hit in one place - you started with one electron,

So what if sound had a wave-particle duality? When you shouted, the sound waves would spread

outwards in all directions, but only one person could hear what you said! Or when you drove

your boat through the water, the waves would travel like normal, but only hit the shore

Now that would make for some pretty boring surfing!
