Computations in the Vertebrate Retina: Gain Enhancement, Differentiation and Motion DiscriminationKoch, Christof, Poggio, Tomaso, Torre, Vincent 01 September 1986 (has links)
The vertebrate retina, which provides the visual input to the brain and its main interface with the outside world, is a very attractive model system for approaching the question of the information processing role of biological mechanisms of nerve cells. It is as yet impossible to provide a complete circuit diagram of the retina, but it is now possible to identify a few simple computations that the retina performs and to relate them to specific biophysical mechanisms and circuit elements. In this paper we consider three operations carried out by most retinae: amplification, temporal differentiation, and computation of the direction of motion of visual patterns.

You cant be a rationalist in an irrational world. It isnt rational Joe Orton 1
It may be argued that a historically accepted model of an academic career begins with having completed a PhD and in so doing identifying a body of theory that will inform and constitute ones practical academic work. While it may be an accepted model it does not necessarily take precedence as the only model. The relationship between theory and practice is symbiotic and as such it is possible, and indeed at times desirable, that practice inform theory. It is not advisable to be solely operating from a position of theory when making creative work; the risk is far too great.
The gravitational force of theory can all too easily disturb the fragile innocence of creativity. Pulled and constrained by the logic of theory the work risks becoming too didactic and its creativity sacrificed for the sake of rationalism
a symptom almost diagnostic of our culture.
I appreciate that the term creative is open to a plethora of readings, each with their own cogent claim to usage. When I employ the term I am referring to a particular type of decision-making process involved in the solution of problems. I will argue that a creative decision differs from other types of decisions [such as, practical or scientific] in the way the resultant solution of the problem remains open to a greater number of potential readings. I will also argue that it is precisely in those heuristic moments of potential impasse, often associated with a problems resolution, where creativity hangs out.
In any creative venture, I have always been guided by the importance and significance of doing2
in the doing is the theory. This is not meant to dismiss theory but simply to see it in much the same way as when we see objects in our peripheral vision. Just as objects in our peripheral vision do not take their place in our visual field3, theory [for me] participates in creative processes by subconsciously serving as an early guiding system that helps monitor the work. In this age of information we are no longer innocent of theory -it is ineluctable. What is crucial is that we have a command of theory in order that we may go through it and regain our creative innocence. If we do not, we only achieve an artificial innocence born of enthusiasm, exuberance and imprecision. Creative innocence is re-found in doing. This assertion conceives of theory as participating as part of a creative subconscious and goes someway towards explaining the sudden epiphany of understanding that is frequently associated with prolonged and intense work, or the immense pleasure at retrospectively recognising the theory that seemed to have informed ones work without being conscious of it -as if the theoretical component had always been there. This phenomenon is of fundamental concern to my thesis, especially when considering the theatre productions that constitute my creative oeuvre. Upon close inspection, my works ultimately reveal that the defining distance between a visceral creative decision [one whose manifestation is immediately felt as apposite] and one that is conceptualised as the illustration of a theory, is not that great
I just happen to begin working outside of the brackets of theoretical narration.
Throughout my thesis I will refer to all visuals as images but I will argue that there are specific types of images, namely signs, symbols and metaphors.
In language the term image can imply more than a verbal description of a purely visual experience; it can also mean the metaphoric, ornamental, rhetorical figurative use of language as opposed to its literal use. 4
For the surrealists image meant more than the representation5 of an external thing in the material world, it also meant the revelation of an internal mental state, a psychological verity occluded from consciousness.
Images [of this kind] were incandescent flashes linking two elements belonging to categories that are so far removed from each other that reason would fail to connect them and that require a momentary suspension of the critical attitude in order for them to be brought together. 6
Having already built a body of practical work [spanning thirty years] the challenge was to see if it was possible to identify a coherent theory that consistently functioned as the catalyst of the work - albeit disparate in its nature. The analytical process proved to be the reverse of that which may be observed in the historically accepted model of academic discourse
where the process is cumulative. In this instance the process was deductive -a forensic assignment akin to tracing the diverse creative elements to their creative source or motivation. The venture proved illuminating in much the same way as when one is asked to crystallise a complex theoretical argument; you have to reinvent the argument in a way that helps to simplify its complexity without attenuating its integrity -a complexity that is well known to you but that eludes the uninitiated reader.
Whenever I try and think about my theatre practice I am vexed -particularly when I filter my own experiences and try and extract the meanings that seem genuinely inherent in them. At first glance it is satisfying because of a sense of coherence or pattern in a whole host of discrete events. However a closer inspection quickly reveals the fractal complexity of the pattern and demands a reappraisal of how we see and decipher it. Any attempt to understand its disparate nature by investigating one part in isolation from the whole proves initially unsatisfying and finally futile, for each part seems to be informed by and refer to other parts, as if participating in a greater organising principle; a principle that resists traditional cartography; one that is best seen as one sees the earth from outer space.7 When the earth is seen from outer space one becomes aware of the greater organising principle [the universe] within which it functions. Similarly it is only when the topology of my work is seen from a distance that its coherence is apparent
the further away one is, the more clearly one recognises its constituent parts.
Despite our desire to lose ourselves in the living depths of a work, we are constrained to distance ourselves from it in order to speak of it. Why, then not deliberately establish a distance that will reveal to us, in a panoramic perspective, the surroundings with which the work is organically linked? 8
When I am in the middle of a theatre production, I have only the slightest idea of how it will end; I trust in the doing, and at the end I am always surprised by what I have created. Ambiguity and paradox and consequently indeterminacy ultimately emerge as the common features of my work; they appear as sign posts that mark a way of finally mapping it. Each individual piece of work remains coherently intact despite its seemingly obscure coalescence with others, but it is when the works intersect at these points of commonality that one may observe the greater organising matrix.
The phenomenological world is not a pure being, but the sense which is revealed where the paths of my various experiences intersect, and also where my own and other peoples intersect and engage each other like gears. 9
If the most unrelated things share a place, time, or odd similarity, there develop wonderful unities and peculiar relationships and one thing reminds us of everything. Novalis 10

The Art of the Technical DirectorOakes, Victoria 01 January 2014 (has links)
The theatrical scenic design process does not end at a picture on paper or with the presentation of a scale model. The design must be translated to the stage. There are a myriad of questions to be answered and decisions regarding construction style, process, material choices, structure, safety, etc. that must be made in order to fully realize the design. In a common, contemporary American production hierarchy, the person that is most often responsible for this translation process is the technical director. Often, the technical director is stereotyped as solely a craftsman or a technician following a set of pre-established directions and not as an artist in his own right. Even I, as a technical director, am guilty of promoting this stereotype for the majority of my theatrical career. However, through reflection on my professional experiences in combination with my education and research over the last two and a half years, I began to recognize the art inherent in the field of technical direction. I have gained a greater appreciation for and understanding of the importance of the artistic contributions made by every participant in a theatrical production. The practice and research based journey chronicled in this document serves to move beyond stereotypes and expose the technical director as a conscientious, collaborative theatre maker and artist.
