The Vapors of Hell

Mark DavisLeave a comment

Since Plutonium has now been unearthed in Turkey–no, not the element, but the gates of the underworld where the Priests of Cybele got drunk on gases erupting from below the water table–it seems only appropriate to trace the historic, mythic, and semantic roots of the notion of Hell out from its roots in antiquity straight through to our modern representations.

We can draw a direct line from Tartarus to the concept of punishment and the afterlife that arose during the Hellenistic period and filtered into the Near East, and what better representation of the dangerous threats from deep beneath the earth than a cave that kills animals and makes people drunk on the fumes? Such a place must have captivated the minds of the ancients by providing a corporeal connection to the mythic dancing of the deities.

The great irony is that the Hierapolis and the Plutonium was bulldozed by Christians in the 4th to 6th century CE, thus destroying a touchstone of their own cosmology.… Read the rest

Signals and Noise: Chapter 00010101 (Ennui)

cover-design-epubWhat does one do when one is only living? What does one do when there is nothing to be done. Waking back to the abandoned reactor was already boring after only one night. It was late in the morning judging from the portals of light in the hall outside his cell. He was famished and athirst as he walked down to the central room. Only a few children milled between smoldering fires. He could smell food, though, and followed the scent. It was bacon, he thought, and his mouth began salivating. He hardly ever ate bacon, but he often craved it. He found older kids cooking in a functioning kitchen, though they had converted the sinks into fire pits and were toasting bread and frying bacon in iron skillets thrust into the hot coals. He waited in line for a helping and gobbled it down with his hands off the tin plate that they handed him. He looked behind the cooks and saw several large, blue coolers filled with milk cartons, eggs, and slabs of meat on top of mounds of ice. Zach thought that they must have brought that in this morning since there was no electricity at the facility.

A boy approached him as he leaned against a wall and drank deeply from the cup of milk that he had been given. You a hacker? the boy asked, stammering and averting his gaze just a bit as he spoke, then raising his eyes directly towards Zach until Zach returned the look. Yeah, I spose. Why? Oh, dunno. I’ve never touched a puter, he said, seeming proud of his accomplishment. Really? Zach asked. How long you been here? The boy grinned at him.… Read the rest

Curiouser and Curiouser

georgeJürgen Schmidhuber’s work on algorithmic information theory and curiosity is worth a few takes, if not more, for the researcher has done something that is both flawed and rather brilliant at the same time. The flaws emerge when we start to look deeply into the motivations for ideas like beauty (is symmetry and noncomplex encoding enough to explain sexual attraction? Well-understood evolutionary psychology is probably a better bet), but the core of his argument is worth considering.

If induction is an essential component of learning (and we might suppose it is for argument’s sake), then why continue to examine different parameterizations of possible models for induction? Why be creative about how to explain things, like we expect and even idolize of scientists?

So let us assume that induction is explained by the compression of patterns into better and better models using an information theoretic-style approach. Given this, Schmidhuber makes the startling leap that better compression and better models are best achieved by information harvesting behavior that involves finding novelty in the environment. Thus curiosity. Thus the implementation of action in support of ideas.

I proposed a similar model to explain aesthetic preferences for mid-ordered complex systems of notes, brush-strokes, etc. around 1994, but Schmidhuber’s approach has the benefit of not just characterizing the limitations and properties of aesthetic systems, but also justifying them. We find interest because we are programmed to find novelty, and we are programmed to find novelty because we want to optimize our predictive apparatus. The best optimization is actively seeking along the contours of the perceivable (and quantifiable) universe, and isolating the unknown patterns to improve our current model.… Read the rest

Minimizing Existential Toaster Threats

Mark DavisLeave a comment

tesla2Philosophy in the modern world has strived for a sense of relevance as the sciences (“natural philosophy”) have become dominant. But philosophy may have found a footing in the complicated space between technological advances and defining human virtues with efforts to address and understand change and its impact on human existence. These efforts have included the ethics of biological manipulation and, critically, existential threats to humanity, including climate change, artificial intelligence, and genetic engineering.

I mention all this because I’m really writing about cars but need to fit the discussion somehow into the theme of this blog. So the existential threat of climate change means we need to pollute less and burn less fossil fuels. More tactically, however, my wife and I also needed to buy a new toaster because our five-year-old Oster four-burner unit was failing. There was therefore only one solution to this dilemma: take the brand new Tesla S 70 miles away to the foothills of the Sierra on a test drive and, yes, to buy a new toaster.

I had taken delivery of our Tesla S Performance 85 with Tech Package a week before but didn’t really have any opportunity to drive it because of work obligations that kept me firmly planted in front of a computer monitor. I had driven it briefly but it mostly sat charging in the garage (at the slowish pace of a 120V circuit; Tesla did not deliver my dual charger station in time and I haven’t had the 100A circuit installed to support it either), so when Saturday came, I realized that it was an opportunity to justify a longish trek to test the drivability of the car and to seek out and use the Tesla “supercharger” stations that promise rapid charging in 30 minutes to an hour.… Read the rest
