Escher Circuits: visual computation programs

Here’s a proper science fictional “what-if?”, via the ever-reliable MetaFilter, where the brilliant slug-line “software for your wetware” was applied: is it possible to exploit the biological computation power of our visual apparatus to deal with tasks that we find difficult at a cognitive level? Or, to put it another way: can we set up the brain to act like a processor that uses complex visual stimuli as a form of program?

Or, even more simply: can we make diagrams that, when looked at, produce a certain computational output in our minds?

Yeah, I know, it sounds a bit crazy… but Mark Changizi sure comes across like he knows what he’s doing.

The broad strategy is to visually represent a computer program in such a way that, when one looks at the visual representation, one’s visual system naturally responds by carrying out the computation and generating a perception that encodes the appropriate output to the computation. That is, there would be a special kind of image that amounts to “visual software,” software our “visual hardware” (or brain) computes, and computes in such a way that the output can be “read off” the elicited perception.

Ideally, we would be able to glance at a complex visual stimulus—the program with inputs—and our visual system would automatically and effortlessly generate a perception that would inform us of the ouput of the computation. Visual stimuli like this would not only amount to a novel and useful visual notation, but would actually trick our visual systems into doing our work for us.

And the visual stimuli he’s on about [image borrowed from linked article]?

XOR gate Escher circuit

Well, that elicited a few cognitions from my brain… though I’m not sure that any of those cognitions are particularly useful.

Beginner’s guide to atom-smashing

Today’s ubiquitous topic in the geek-o-sphere is surely the successful test of the Large Hadron Collider at CERN… so if you were wondering exactly how it is that particle accelerators are supposed to discover hypothetical sub-atomic thingybobs with funny names, Ars Technica is running a series of articles that should fill you in on the basics. Start with Everything You Ever Wanted to Know About Particle Smashers, and proceed from there.

Redefining karma and building reputation economies

An interesting and lengthy overview post from Randy Farmer and Bryce Glass, authors of the book Building Web Reputation Systems, on (unsurprisingly) the basics of building web reputation systems [via MetaFilter].

I’ll swap ten whuffie points with anyone who has the time to buy and read this book on my behalf and give me a succint 10-page precis thereof…

Dude, where’s my island?

Since around 2005, at least 24 small islands have effectively vanished from the Indonesian archipelago. While sea levels are rising quickly enough to make some islands vanish (and solving long-running turf disputes in the process), these particular islands are not victims of climate change, but of ‘sand pirates’ digging them up and shipping them away to be used as building aggregates on the mainland [via Technovelgy].

Given the vast amount of stuff we put into landfills around the world, maybe we could build some new islands from McMansion rubble and consumer electronics junk?

The Worst Science Fiction Series EVAR.

Sorry for things still running at reduced capacity here at Futurismic, but I’ve rather a lot on my plate right now, and that looks to continue until after Easter at the earliest (though I’m busy over Easter weekend because of Eastercon, which is a nice sort of busy by comparison to the rest).

But I don’t want y’all to get bored, so I’m going to do my best to do a few posts a day just pointing to interesting stuff elsewhere… skipping my usual discursive and directionless rambles, in other words! So try this one for size: after seeing some other website list Asimov’s Foundation series as the pinnacle of written science fiction, Ian Sales has compiled a retaliatory list of the ten worst science fiction book series, books “whose label as science fiction embarrasses me, whose continuing popularity puzzles me, and whose fans I feel deserve a smack upside the head with a very large and nail-studded cluebat.”

I still hold a soft spot for the Pern novels (as they were my road-to-Damascus sf texts as a child), but I’m not ashamed to agree with a lot of Ian’s other selections. What about you? Which of Ian’s picks would you rescue from the sin-bin, and which series would you add to the list?
