19 Mar At the Edge of Possibility
Does the universe of probability have boundaries? Are there physical laws that control all phenomena, or is there a mystical, capricious random power out there that is not subject to the laws of physics? Is anything impossible? Physical laws are responsible for thresholds. Let us presume, for a moment, that probability is subject to one overriding […]
11 Mar Joe’s Theory of Everything
While my teachers explained that language is about nouns and verbs, I think language is about symbolically representing everything and communicating about anything to anyone. There are many ways to look at the milieu in which we live from the tiniest sub-atomic particle on up. One way is to look at the larger context of […]
05 Mar Decide on Fuzzy Logic
In this section of Understanding Context, we describe not just how people think, but how they use their thoughts to guide their actions. We are particularly concerned with how people integrate multiple ideas or constraints into their thinking and decision-making processes, then put those decisions into action. It is sometimes said that the difference between information […]
24 Feb Neural Network Perception
Feedback in Image Processing While the flow of electrical impulses in the brain triggered by visual stimuli travels sequentially through layers I then II then III of the visual cortex, this directional flow does not prevent impulses from other sources, including feedback loops within the visual cortex from contributing to our ability to process images. […]
20 Feb Learning Cause and Effect
Sparks of Kinesthesia When does a person begin to learn about the relationships between things that happen? Does the brain have an innate capacity to make the connections necessary to associate outcomes with catalysts? At what point does a person begin to learn that she or he can affect outcomes in the real world? One […]
19 Feb Dichotomy vs. Continuum
Consciousness, it appears from our recent discussion, is not an “on or off” proposition. We have subconsciousness, waking consciousness, consciousness during sleep, and so on. Before that we spoke of the yin and yang of perception and learning. Since the subject of this series is cybernetics, we shall diverge from our discussion of consciousness long […]
30 Jan From Aristotle to the Enchanted Loom
“Swiftly the brain becomes an enchanted loom, where millions of flashing shuttles weave a dissolving pattern-always a meaningful pattern-though never an abiding one” (Charles Sherrington). What of the centillion warps and woofs of ideation? Does it never abide? Passing seems to take away all that was ever weft, unless the Gods endow immortality on our thoughts and carry them […]
13 Jan Harmonic Convergence of Light
Light waves diverge and converge and bend on their journey to places where they are perceived. We choose to focus, perceived light waves enter us through the portals of our eyes, then flow through the visual cortex and resonate in the brain until they trigger recognition, often very quickly. The illustration shows a lens that […]
31 Mar Asymmetrical Balance, True Love and Chaos
Inequality is the Pattern Unequal distributions characterize everything in the universe from subatomic particles to galaxies. In fact the whole idea of “equality” in the physical universe seems at least a tiny bit sketchy. At the extreme end of unequal distributions is chaos. On the near end are things that approximate equality: balance, parity, equal opportunity, symmetry […]
24 Feb Intro to the End of Code
By: Joe Roushar – February 2013 In the Beginning When computer programming began, it consisted mostly of written computer instructions called code. Data was minimal. Decks of dozens to hundreds of punched cards told the computer what to do with the data, which was also encoded on punched cards. The process of writing and debugging code was tremendously tedious. As computing […]
