“havent slept in 105 hrs. my eyes are burnng horribly an seem to be bloodshot. as far as reaction time goes, its almost nonexistant. i had friend throw something at me, and didnt even bother flinching.”
I’m pretty much fascinated with the Whitney Music Box, which explores some of the ideas in John Whitney’s 1959 book Digital Harmony. I like the microtonal variation, and the sine wave harmonics are cool because harmonics are inherently cool. Jim Bumgardner wrote more about this project and some of the mathematics of the patterns in his blog.
Lots and lots of maps of the brain. Kind of gross, all lumpy and pale.
The Cassini spacecraft has sent back some new images of Saturn. There’s a cool time-lapse video of making an orbit around the rings, with the moons zipping by in the background.

“We ended up at one point lying on the snow, looking up at the sky and talking about the food chain and how the sun indirectly supplies energy for our bodies. It was pretty idyllic all around.” I love it. That’s the mix of blissful goofing off + learning that I loved when I was a kid. Playing, learning, creating, it’s all the same. I hope I’ll get to share that one day with kids of my own. Sledding, photosynthesis, snowball fight, maybe a little praxeology with the afternoon snack…

I love it when professors put their materials online. John Boyd, professor at University of Michigan, has his lecture notes for Engineering 503: Scientific Visualization & Information Architecture. The second chapter is called “The Gospel According to Tufte”. It’s a wonderful collection that I’ll be spending some time on this weekend.
Kottke points to some pretty amazingly intricate origami creations by origamist/ scientist Robert Lang. Pretty amazing little creations.
Ah, vindication. When I’m at work, I make a point to take a nap every day. Sometimes I’ll even squeeze in a second one. A recent long-term study has shown that “among working men who took midday naps, there was a 64% reduced risk of death” from heart disease. I knew I was on to something! [via kottke]
Down and Out in the Magic Kingdom (review: 5/5)
This book reminded me how much I love science fiction. Down and Out in the Magic Kingdom (which, per Cory Doctorow‘s tradition, you can download for free) takes place in a transhuman future. Poverty, scarcity, and sickness have been pretty much eliminated. Our hapless narrator-hero, Julius, has been killed (again) and his rivals are trying to take over one of his pet projects where he works at Disneyland. He fights back with the help of tenuous friendships and ill-formed plans, and it’s pretty much wonderful the whole way through.
One of the best parts about great science fiction (and I think this one counts) is just taking a few ideas and seeing where they lead, a sort of narrative thought experiment. Luckily Doctorow doesn’t get too explicitly philisophical, but there is some great hypothesis-spinning daydream material here. What if we were all networked, able to be really, individually connected to each and every other person? How does society recalibrate value where material scarcity no longer exists? If you could freeze your life for 500 or 10,000 years and wake up later, well… what would that be like? What’s the effect on human relationships? All this, and more. Go read it.
New techniques in astronomy have allowed us to create multi-dimensional maps of dark matter. This is huge, we still just need to figure out what the stuff is. [via justin blanton]
A few weeks ago, China’s anti-satellite missile test generated at least 517 pieces of debris big enough to be tracked. Those images are wild. We are being orbited by enormous amounts of our own crap. Tragedy of the commons, I guess.
An interview with anthropologist Barbara King.
I think we have evolved to believe in transcendent realities. What we’re about as a group of humans on this earth is believing that there’s something more than us. It takes many different forms. I don’t know that I’d focus on a single transcendent reality. I would say that because we’re made to relate, we think and feel that we’re in relationship with something bigger.
King is exploring the evolutionary roots of religion by studying our sister species like apes and bonobos and chimps. Her research is looking into the “embodied” aspects of religion, rather than doctrine, per se. She’s all about this sense of spiritual awe, of empathy, and of self-awareness as a speciesÄî”because we’re made to relate, we think and feel that we’re in relationship with something bigger.” [via rebecca blood]

Letter to a Christian Nation (review: 3.5/5)
Atheism seems to have caught a little buzz in recent years, I’m not sure how. There was that unfortunate survey, and books by Dawkins and others made a little splash, and there’s the cover story on a recent issue of Wired magazine, in particular. Sam Harris’ extended essay, Letter to a Christian Nation, joins the crowd with a missive to “demolish the intellectual and moral pretensions of Christianity in its most committed forms.”
Harris has some really great moments in this book, and it’s a pretty compelling read. He starts with a heavy does of scripture, analyzing the Christian moral paradigm, delighting in the Bible’s weaknesses and cherry-picking the incriminating and contradictory parts. I’m certainly (absolutely) not a Bible scholar, but I think he’s a bit too reliant on quoting from the Old Testament, where Big Bad God and the harshness and shortcomings of ancient civilizational mores are far too easy to pick on. You have to keep in mind that he’s targeting the literalists more so than religious liberals and moderates. But there’s also some interesting sociological examination of religion: “Religion raises the stakes of human conflict much higher than tribalism, racism, or politics ever can, as it is the only form of in-group/ out-group thinking that casts the differences between people in terms of eternal rewards and punishments.”
I think he’s effective when he’s talking about the practical, day-to-day implications of religion more so than his examination of the particulars of doctrine. He has a nice section on the ethics of life, discussing abortion, cloning, and biomedical research. And of course, there’s an obligatory passage on evolution and intelligent design. Here’s one line that really got me: “The core of science is not controlled experiment or mathematical modeling; it’s intellectual honesty.”
The last section is a gloomy look to mankind’s future on an increasingly religious, conflict-ridden planet.
It is easy, of course, for the representatives of the major religions to occasionally meet and agree that there should be peace on earth, or that compassion is the common thread that unites all the world’s faiths. But there is no escaping the fact that a person’s religious beliefs uniquely determine what he thinks peace is good for, as well as what he means by a term like “compassion.”
Practically, is there really room for tolerance? He wraps up with a big, brilliant question, “How can interfaith dialogue, even at the highest level, reconcile worldviews that are fundamentally incompatible and, in principle, immune to revision?” The stakes are indeed very high.
Steven Pinker writes about the mystery of consciousnessÄîthe biology of the soul and the moral implications of when we finally find it. The two big challenges: the Easy Problem, distinguishing the brain’s participation in conscious and unconscious thoughts and how they evolved, and the Hard Problem, explaining first-person subjective experience as neural activity.
