A recent physics assignment:

"THE PROBLEM OF CONSCIOUSNESS A Talk with Alva Noë"
The central thing that I think about is our nature, our human-animal nature, our being in this world. What is a person? What is a human being? What is consciousness? There is a tremendous amount of enthusiasm at the moment about these questions.They are usually framed as questions about the brain, about how the brain makes consciousness happen, how the brain constitutes who we are, what we are, what we want—our behavior. The thing I find so striking is that, at the present time, we actually can't give any satisfactory explanations about the nature of human experience in terms of the functioning of the brain.
What explains this is really quite simple. You are not your brain. You have a brain, yes. But you are a living being that is connected to an environment; you are embodied, and dynamically interacting with the world. We can't explain consciousness in terms of the brain alone because consciousness doesn't happen in the brain alone.
In many ways, the new thinking about consciousness and the brain is really just the old-fashioned style of traditional philosophical thinking about these questions but presented in a new, neuroscience package. People interested in consciousness have tended to make certain assumptions, take certain things for granted. They take for granted that thinking, feeling, wanting, consciousness in general, is something that happens inside of us. They take for granted that the world, and the rest of our body, matters for consciousness only as a source of causal impingement on what is happening inside of us. Action has no more intimate connection to thought, feeling, consciousness, and experience. They tend to assume that we are fundamentally intellectual—that the thing inside of us which thinks and feels and decides is, in its basic nature, a problem solver, a calculator, a something whose nature is to figure out what there is and what we ought to do in light of what is coming in.
We should reject the idea that the mind is something inside of us that is basically matter of just a calculating machine. There are different reasons to reject this. But one is, simply put: there is nothing inside us that thinks and feels and is conscious. Consciousness is not something that happens in us. It is something we do.
A much better image is that of the dancer. A dancer is locked into an environment, responsive to music, responsive to a partner. The idea that the dance is a state of us, inside of us, or something that happens in us is crazy. Our ability to dance depends on all sorts of things going on inside of us, but that we are dancing is fundamentally an attunement to the world around us.
Consider this. On the traditional conception of the mind, if you want to study experience, you shut your eyes and you introspect. You look inward and reflect on what is going on inside of you, on the inner show. But if experience, if seeing, hearing, thinking, and feeling, isn't something going on inside of you, but is something you do, then you need a different paradigm of what phenomenology would be, that is, of what a reflection on experience itself would be.
To reflect on experience is not to look inward, it is to pay attention to what you are doing, and to the way in which what you are doing is world and situation and environment involving. Suppose I am a hiker. I walk along and move my legs in all sorts of subtle ways to follow a path along a trail. But the steps I take and the way I move my legs are modulated by, controlled by, the textures and bumps and patterns of the trail itself. There is a kind of locking in. To study experience, to think about the nature of experience, is to look at this two-way dynamic exchange between world and the active perceiver.

One experience that I've been especially interested in is our understanding and experience of pictures. If I show you a picture from a newspaper—for example, a photo of Hillary Clinton—there is a sense in which, when you look at that picture, you see Hillary. There she is, in the picture. Of course, Hillary is not there, so there is an obvious sense in which you don't see Hillary when you look at the picture. There is a sense in which you see her; and a sense in which you don't. She shows up for you, in the picture, even though she is not there. She shows up as not there. Getting clear about this phenomenon is the central empirical and conceptual problem about depiction.
One idea might be to say, well, seeing a picture of Hillary is just like seeing Hillary. Seeing a picture of Hillary produces in you, the perceiver, just the same effects that actually seeing Hillary would produce. The problem with that suggestion is that if that's right then we lose our sense of the difference between seeing Hillary and seeing a picture of Hillary. The distinctive thing about seeing Hillary in a picture is that she is there but not there. She is there but visually absent. She is manifestly absent in her visual presence. It's a kind of a paradoxical thing. There is something paradoxical about pictures.
My view is that traditional philosophy and cognitive science has been asking the wrong question when it comes to pictures. They ask, how does the picture affect us and give rise to an experience in our heads? Instead, what they should ask is how do we achieve a kind of access to Hillary, to properties of Hillary, such as her visual appearance, by exploration of something which is not Hillary, namely, a picture?
The critical thing is the relation between this model, this picture, and that which is absent, such that we can gain access to what is absent in the picture. Once again we are thrown back to this idea that the perceiving is an achievement of access by making use of skills, knowledge. I need to know what Hillary looks like in order to recognize Hillary in her picture.

The division between philosophical and empirical approaches to these questions of consciousness, understanding and experience is an artificial one. People interested in the mind, have a set of questions that they want to understand: what is thought, what is emotion, what is consciousness, what is cognition? How is it that we are able as the animals we are able to do all this? Philosophy and science have been working on this together.
In fact, most of the science grows out of philosophical discussions. It is sometimes said by scientists that now that we have the new technologies of brain science we no longer need to pay attention to what philosophy has to say about these questions. But in fact—and this is just plain truth—most of what empirical science has to say about consciousness, language, memory, perception, emotion is the expression of a philosophy. It comes out of an investment in a particular philosophy, namely the philosophy of the internal, the philosophy of the individual: the mind is something inside each individual; it is disconnected from other people and from the body and from the outer world. If natural science is to gain a foothold in this area, if our own nature is to become subject of empirical science, it can only be because the conceptual, methodological, philosophical, as well as empirical questions are approached in a new, open-minded way.
Scientists ask, what is it about the way these cells are firing in the brain that makes the corresponding experience a visual experience? It's a trick question because there is nothing about the way those cells are firing that can explain that. Certainly we don't now know anything that would allow us to point to the intrinsic properties of the cells and say, it's something about the intrinsic behavior of these cells that makes the resulting experience, the smell of coffee on a rainy morning, or the redness of red. Nor can we say that populations of cells give you the solution.
We have to get bigger than that. It's not one cell; it's not populations of cells. We need to look at the whole animals' involvement with a situation. The thing about a smell is that a smell gives you the space of possible movement sensitive changes. If I am smelling something, the movements of my nostrils in relation to the source of the order will produce changes in the character or the odor. If we want to ask, what is it about this cellular activity that makes it olfactory cellular activity, the answer is going to be the way in which the cellular activity varies as a function of the animal's movement.
And that is what the brain is doing. The brain is enabling us to establish this kind of sensorimotor engagement with the world around us. This is a substantive empirical hypothesis that I am putting forward. There are profound philosophical reasons to embrace it. And I hope that scientists and philosophers will find ways of communicating so they can work on these questions together.
1) In your own words, what is this article about?
2) Is this author making an argument towards a specific type of thinking? If so, in your own words, what is this argument?
3) How does this article reflect the continued adaptation of science to the current “mind-set” of culture?
4) Ok, so this has nothing to do with Physics, so, why would I ask you to read and interpret it? How can the general concept of this article be related to physics?

granted my mind is mush from two days of the flu (thank you ernie) and my environment is surrounded by an energy drink that tastes like a blue crayon, but i suspect you will not get fired for asking students to think regardless of how the "thinking" is processed, my bet is that you will be pleasantly surprised with the depth of their work.
