In 1850, a farmer found a secret village. It was later determined to be older than the Great Pyramids of Egypt. Archeologists estimated that 100 people lived in this village named Skara Brae, the "Scottish Pompeii." The houses were connected to each other by tunnels, and each house could be closed off with a stone door.

American elections are crazy. I know gerrymandering can happen in many voting systems, but the american system has that on top of every other possible flaw with a voting system.

hello dear physics explainer, can you explain to me how/why photons are both a wave form and a particle?

oh that’s easy. light isn’t a wave or a particle.

I mean that’s it’s not a wave, and it is also not a particle.

light is light. it is a strange substance that has a lot of strange properties. we can model the behavior of light in a few different ways, however. If we are working with light and we are interested in interference, then it is useful to model it as a wave and treating it as a wave will predict its behavior reliably. If we are trying to do something with the photoelectric effect, then it’s far more useful and predicative to model light as a particle.

think of it like map projections. this is the mercator projection:

it wildly distorts geography the closer you get to the poles, so it is not useful for finding the area of any sea or landmass; however, the lines of longitude are perfectly straight, which makes it a very useful map for navigation.

This is the Goode-homolosine projection:

This is quite a good map for accurately finding the area of landmasses. But because the lines of longitude point in different directions across the map, it’s worthless for navigation.

asking why light is both a wave and a particle is like asking why the Earth is both Mercator-shaped and Goode-homolosine shaped. It isn’t. It’s not. The earth is round. We just need multiple models in order to interpret it two dimensionally.

photons are quantum objects. the only way to accurately model them in totality is via quantum theory. but that isn’t useful for most of the things you’d want to measure photons for, because it’s much too complex. wave-photons and particle-photons are both practical simplifications of quantum-dimension objects.
