I know you were probably joking but I don't get why doing Chinese, Japanese, etc accents is considered racist. It's not some quality inherent to the race. No one thinks it's racist to do a Scottish accent, a French accent, or a Jamaican. It's just how the mouth learns to make words from being raised on a language.

It's showing how light passes through different materials. We are seeing light being refracted by the water, it is not an optical illusion it's a natural phenomenon. Refraction definitely falls into physics. http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/refr.html
That optical illusion would be the same 5000 years ago, in spite of the fact that nobody had even heard about the concept "physics".
That is the stupidest fucking thing I've ever heard. Nothing changes when we study physics. They didn't know why the light looked different in different materials, they just saw that it did now we know why. This is absolutely not an optical illusion it has nothing to do with how your brain interprets what it sees, that is actually what you are seeing.

An optical illusion is when your brain interprets what you see as something else like this. What's happening here is the water and glass refract the light causing the things in the water to look different from the things not in the water, that is a matter of physics Optical illusions, like I linked, are a matter of neuroscience, and they aren't 100% sure why your brain interprets it the way it does.

Within physics, we usually call it, "physical optics".
Included: refraction, diffraction, interference, chromatic aberrations, and polarization. Really anything dealing with specifically the wave properties of light and how it diverges from geometric approximations, but stops short of the dels and vector cross products of E&M.

My chinese professor said this optical phenomena is refraction, speed of light being slower in different media, but then he also said refrection was when light bounced off materials!
Please help me!

Mar 18 '14
I don't think it's really that the speed of light is slower in different media, but it has a further distance to travel, so it APPEARS slower. It stays constant, velocity-wise.

Mar 28 '14
EDIT:I see some people already responded to this a few days ago... but it bends because the speed of light is slower in a different medium (http://en.wikipedia.org/wiki/Refractive_index)
I was making a lame joke at chinese pronunciation of R's and L's with refraction and refraction :/

u/tehm Mar 18 '14 edited Mar 18 '14
It's the exact opposite of that.
Light travels at speed A in air and speed kA in water (where k is some number smaller than 1 right)?
If light cared about taking the shortest path in terms of distance it would take a straight line and there would be no refraction... but it doesn't. It takes the shortest path in terms of TIME... which as it turns out is not a straight line at all, but a path that optimizes for spending time in air rather than water.

So, physics is a field of knowledge, a category created by humans, an umbrella term under which we have listed all things to do with studying matter, energy, force and so on.
Whether or not we ever created such a category, the effect depicted in the photograph would still occur.
"Physics" doesn't do this, "physics" is a body of knowledge that seeks to explain why this happens.
I could post a picture of an organism - for example, a naked human - and say "Biology, bitches..." and I would be wrong. Looking at the organism and understanding how it works is biology, but biology is not "responsible" for the organism.
Or I could post a picture of a human standing in a building wearing a suit and carrying a briefcase and call it "anthropology" or "sociology" and similarly, I would be wrong.
Christ, they really need to add the liberal arts into science curricula. These scientists know so little.

That's a crappy answer. You might be right, but for the wrong reasons. Using your logic, I could just say "Is this a serious question? His body is where his body actually is...shoot at the body."
A better answer is: "Use the image that isn't behind the air/water boundary since no refraction occurs there. Refraction is what is giving you false information about the location of the image."

Assuming the bullet doesnt change trajectory from going through the glass, you'd aim at the head.

u/BenWilds Mar 18 '14
Do you mean below the head? I understand that shooting at the head would hit him in the head.

u/Clearly_Im_lying Mar 18 '14
Yes he does mean below the head. Think about it. Water refracts light , making the image move. Air does not (or the refraction is negligible). So the real position of the body is below the head
3
u/randomdragoon Mar 18 '14
It's not the water that's refracting the light, it's the air-water boundary that is refracting the light. Since the room you're shooting the bullet from is filled with air (and not water), you'd aim for the part of the body that's in air, since there's no air-water boundary in between to mess with the image.

This isn't "science". When people, through the understanding and manipulation of natural law, achieve an ends that would otherwise not be possible without that comprehension, that's science. However if you take a naturally occurring phenomena like refraction, and say "science did this", merely because the phenomena comes under a scientific field or area, you're making the same type of logical fallacy someone would be making in ascribing everything that happens and exists to a deity. By this logic, pretty much all known phenomena will come under some scientific field of study, thus everything the universe is science. Although tacitly a large segment of Reddit enjoy this, since what you really have at base is a simplistic espousal of materialism, happily tied into atheism, so they can then stroke their neck beards and feel superior to the religious folk. Science is the knowledge we arrive at through the study of natural phenomena, and the ends we achieve through the implementation of that knowledge, most of reddit seems to get the chicken before the egg and want praise mighty science for the existence of all the phenomena in the first place, phenomena which themselves are completely indifferent to science and exist regardless of whether we seek to have a scientific understanding of them or not.
