The Science of the Matrix
KamehamehaWarrior writes "Peter B. Lloyd, author of Taking The Red Pill: Science, Philosophy, and Religion in The Matrix, believes that many of the plot developments in "The Matrix" that seem to contradict the laws of physics, biology, etc. can actually be explained with a closer look at the science. He addresses issues such as "Can humans really be an energy source? How does the Matrix know what fried chicken taste like? Why do the rebels have to enter and exit the Matrix via a telephone system (that doesn't actually exist)?""

GLITCHES IN THE MATRIX . . . AND HOW TO FIX THEM
by Peter B. Lloyd
Why, exactly, do the rebels have to enter the Matrix via the phone system (which after all doesn't physically exist)? And what really happens when Neo takes the red pill (which also doesn't really exist)? And how does the Matrix know what fried chicken tastes like? Technologist and philosopher Peter Lloyd answers these questions and more.

As the essays throughout this book demonstrate, the Wachowski Brothers designed The Matrix to work at many levels. They carefully thought through the film's philosophical underpinnings, religious symbolism, and scientific speculations. But there are a few riddles in The Matrix, aspects of the film that seem nonsensical or defy the laws of science. These apparent glitches include:
The Bioport--how can a socket in your head control your senses? How can it be inserted without killing you?
The Red Pill--since the pill is virtual, how can it throw Neo out of the Matrix?
The Power Plant--can people really be an energy source?
Entering and Exiting the Matrix--why do the rebels need telephones to come and go?
The Bugbot--what's the purpose of the bugbot?
Perceptions in the Matrix--how do the machines know what fried chicken tastes like?
Neo's Mastery of the Avatar--how can Neo fly?
Consciousness and the Matrix--are the machines in the Matrix alive and conscious? Or are they only machines, intelligent but mindless?
This essay addresses these questions and shows how these seeming glitches can be resolved.
THE BIOPORT
Can the machines really create a virtual world through a bioport? And how does it work? The bioport is a way of giving the Matrix computers full access to the information channels of the brain. It is located at the back of the neck--probably between the occipital bone at the base of the skull, and the first neck vertebra. Wiring would best enter through the soft cartilage that cushions the skull on the spinal column, and pass up through the natural opening that lets the spinal cord into the skull. This avoids drilling through bone, and maintains the mechanical and biological integrity of the skull's protection. A baby fitted with a bioport can easily survive the operation.
The bioport terminates in a forest of electrodes spanning the volume of the brain. In a newborn, the sheathed mass of wire filaments is pushed into the head through the bioport. On reaching the skull cavity, the sheath would be released, and the filaments spread out like a dandelion, gently permeating the developing cortex. Nested sheaths would release a branching structure of filamentary electrodes. As each sheathed wire approaches the surface of the brain, it releases thousands of smaller electrodes. In the neonate, brain cells have few synaptic connections, so the slender electrodes can penetrate harmlessly.
With its electrodes distributed throughout the brain, the Matrix could deliver its sensory signals in either of two places: at the sensory portals or deep inside the brain's labyrinth. For example, vision could be driven by electrodes on the optic nerves where they enter the brain. Artificial signals would then pass into the visual cortex at the back of the brain, which would handle them as if they had come from the eyes. Correspondingly, outgoing motor nerves would also have electrodes at the boundary of brain and skull. This simple design mirrors the natural state of the brain most closely. It is not, however, the only possibility. Electrodes could alternatively be attached in the depths of the brain, beyond the first stages of the visual cortex. This would greatly simplify the data processing. In normal perception, most of the incoming information isn't processed; information you aren't paying a

"The destruction of a value which is, will not bring value to that which isn't." -John Galt
(continued where the parent got cut off) ... On the other hand, a creature might be profoundly stupid and still have subjective experiences.
Agent Smith is an example of a machine that manifests humanlike behavior--which, if you witnessed such words and gestures in a human, you would immediately regard them as showing conscious emotions and volitions. Indeed, it is the immediacy of the interpretation that is deceptive. When you see someone laugh with joy, or scream in pain, you do not knowingly infer the person's mental state from those outward signs. Rather, it is as if you see the emotions directly. Yet, we know from accomplished actors that these signs of emotions can be faked. Therefore, you are indeed making an inference, albeit an automatic one. It is a job of philosophy to scrutinize such automatic inference. When you see another human being emoting, your inference is not based wholly on what you see, but also on background information (such as whether the person is acting on the stage). More fundamentally, you are relying on the reasonable assumption that the person's behavior arises from a biological brain just as yours does. Whenever those premises are undermined, you inevitably revise any inferences you have made from the emoting. If the emoting stops and people around you clap, you realize it was a piece of street theatre, and the person was only acting out those emotions. Or, if the person has a nasty car accident that breaks open his head, revealing electronic circuitry instead of a brain, you realize that it was only an android and you may conclude that it was only simulating emotions.
A key step in the inference is the premise that the emotion plays a role in the causal loop that produces the outward words and gestures. If, instead, we have established that the observed words and gestures are wholly explained in some other way, without involving those emotions--then the inference collapses. The exterior emoting behavior then ceases to count as evidence for an interior emotional experience. If we know that an actor's words and gestures are scripted, then we cease to regard them as evidence for an inward mental state. Likewise, if we know that the words and gestures of an android or avatar are programmed, then they too cease to support any inference of a mental state.
In an android, or in a software simulation of a human such as an agent, words and gestures are produced by millions of lines of programmed software. The software advances from instruction to instruction in a deterministic manner. Some instructions move pieces of information around inside memory, others execute calculations, others send motor signals to actuators in the body. Each line of code references objective memory locations and ports in the physical hardware. It may do so symbolically, and it may do so via sophisticated data structures, for example, using the tag "vision-field" to reference the stabilized and edge-enhanced data from the eye cams. Nevertheless, nowhere in the software suite does the code break out of that objective environment and refer to the enigmatic contents of consciousness. Nor could the programmer ever do so, since she would need an objective, third-person pointer to the conscious experience--which, being a subjective, first-person thing, cannot be labeled with such a pointer.
Everything that the android says and does is fully accounted for by its software. There is no explanatory gap left for machine consciousness to fill. When the android says, "I see colors and feel emotions just as humans do," we know that those words are produced by deterministic lines of software that functions perfectly well without any involvement of consciousness. It is because of this that the android's emoting does not provide an iota of evidence for any interior mental life. All the outward signs are faked, and the programmer knows in comprehensive detail how they are faked.
This point is systematically ignored by the mathematicians and engineers who enthuse about artif
The theory of relativity doesn't work right in Arkansas.
actually it bears more of a resemblence to the evil deciever arguement Descartes makes in Meditations on First Philosophy. basically Descartes supposes that there could be some all-powerful being tricking us in every way possible so that the reality we believe in is totally false. then he goes off and does some really funky stuff like proving the existance of God.

Didn't Neo steal some guy's cell phone while trying to escape the Matrix, yet was able to use it to communicate with the Nebuchadnezzar? Didn't Cypher use his cell phone to dial a traceable number within the Matrix to tip off the Agents to their location?
I think a better explanation would be that cell phones can't be used because they are portable. Therefore, they cannot be "attached" to a specific volume of space. Moving al the information for an avatar from one network node to another as they move from room to room would be ridculously prohibitive, so the node that stores the information for a specific volume of space would not necessarily include portable objects like cell phones, or avatars.
Instead, the node containing the volume would contain references or identifiers to the objects within that space.
Therefore, cell phones cannot be used reliably to associate the node containing the volume with the node containing the avatar, since the cell phone itself may be on a third node all by itself. A hard line, however, would be a permanent fixture (or semi-permanent if the machines practice refactoring), so the node containing the volume of space would be gauranteed to be be the one that references the avatar.
The cell phone would not directly reference the avatar because it is not a volume of space (it would be like trying to find out what hotel you're staying in by asking, say, one of your shoelaces).
While I'm sure that explanation has its own set of holes, it makes more sense (to me, at least) than the one in the essay.

I'd have to say the Movie I think came closest to it, as far as entire world staged, big guys running the show would have to be Dark City. Very few every heeard of it but those I make watch it seem to agree that Dark City is the Matrix Trilogy compressed into a movie.
