Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! And this topic is really important because, well, we are all made of these quantum objects that behave so mysteriously.
“Wave-particle duality” simply means that a quantum particle has the ability to be measured and observed both as a solid stable object located in a precise location and space, and as a non-physical non-local wave smeared out across space where it can be measured as being in more than one place at the same time. It literally flips-flops in and out of being a solid object and a wave. These objects, such as electrons and protons, make up atoms which are the building blocks of all physical reality.
Here are two very short and concise videos talking about this phenomenon:
We experience a world of physical matter, but in reality, matter is just empty space and electrical spin. There is still so much we have to learn!
