Double-slit

Fyi, there's a lot of woo woo (edit: apparently racist term) crap out there that tries to make you believe that somehow the photons can feel that a human is watching them and they choose to behave differently as a result. This is not true. It just means that when you use a detector or some sort of probe that physically interacts with the photons they change their behavior. It's not magic.

This never gets old.

That's the best use of that meme I've seen.

Shit. That maybe the most clever meme I've ever seen.

NO FAIR! You changed the outcome by measuring it!

Can someone who understands science explain this to me (what im getting at is its a pregnancy test)

That's the best use of this meme I've ever seen. Bravo.

Very clever, made me laugh

You can see all the stripes when you do this. The demonstration is about light's property as a wave.

This is a picture of water so you can see the waves spreading out from the hole. Light does the same thing. And when you have two holes next to each other, the peaks and valleys of the wave will interact with each other.

Now imagine a vertical line where those waves are interacting to the right of the holes. If this were light and the line you imagined was a wall, the parts of the waves that are high are bright and the valleys are dark.

So how long until someone comes in here and claims that this it disproves materialism?

"But but the Double Slit!" Is my favorite pseudoscience argument

Can someone post a search term or some other clue so we can learn?

Fucking brilliant! And all of the upvotes assure me that I'm hanging out with the right bunch of nerds on the internet!

More like double-slut lmao

Brilliant. Do you call this quantum consciousness, quantum mind or something? At least in German its Quantenbewusstsein. After all these years i remember that photons notice you observe them and behave differently, because it's ducking interesting.

The double slit expiriment demonstrates the duality of the nature of a photon: that it's both a wave and a particle.

When a photon is "observed" (or detected) it has the properties of a particle. However when it's travelling it acts like a wave and can demonstrate interference patterns with other photons.

So when you pass photos through two tiny slits, instead of them just passing right through like a particle, they interfere with each other and when the wave pattern collapses when it is observed on the wall, you see the interference.

That being said, I don't think this cartoon makes sense. I get what they are driving at, as they are saying it acts differently when not observed, but this is not what happens. Also this isn't a ln experiment that deals with observation forcing an outcome, but as I noted it's about the duality. Additionally, the wave pattern on the top is what you would you observe when looking at, so I'm not sure why that is what it would be like if you were looking away.
