AI Thread Summary
The phenomenon of seeing one side of an object as blue and the other as reddish is likely due to chromatic aberration, where light is refracted differently at the edges of a lens. This effect can occur in both optical lenses and the human eye, particularly under specific viewing conditions. The discussion suggests that imperfections in lens shape may contribute to this visual experience. Understanding chromatic aberration can clarify whether the perception is a result of vision or physics. Overall, this visual effect is a combination of both optical physics and the characteristics of human vision.

when i look at something very very carefully, one side seems blue and the other seems redish(at the border). I was wondering if
1.Im crazy
2. Its a eye/lens/vision thing

Both! :smile: Google on "chromatic aberration" and you'll get an idea of what's happening.
 
Could you be a little more specific? Under what conditions are you looking at this something very very carefully?
 
chroamtic abberation is when the outer edges of a lens refract light, like a prism, so maybe that is what's happening with your eyes. i think this has something to do with imperfections in the lens shape.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
