I recently mentioned a parable about grains of rice and a chessboard. If you were industrious enough to try your own interweb search for [parable 64 squares grains] you might be ahead of me. Or you may have known the parable already. For the rest of you, here’s the deal.
Stripped of the narrative, it’s about taking a chessboard and placing a single grain of rice in the first square (in some versions, it’s a grain of wheat). In the second square, place two grains of rice—double the amount in the first square. In the third square use double the grains of the second square. For each square on the chessboard, use twice as many grains of rice as used for the previous square.
I’ll come back to the punchline, but I stripped the narrative. Let me fix that.

I had a small dinner party last night so that some friends could come over for some ‘za and beer and catch up on the latest antics of Nancy Botwin and company on Weeds. Per the old saying, “A good time was had by all.” Or to put it less passively, “As usual, we had a blast! (And that Nancy… craaaaaaa-zy!!)”
However, in the course of conversation I realized not everyone knows about the magic behind our north star (Polaris by name) and found myself taking the virtual podium to explain. It’s one of those things that’s common knowledge to many but may come as a complete surprise to others.
So, for those of you not familiar with the navigational magic behind the north star, here’s the deal.

My recent post about how the Big Bang and “Let there be Light” seem equally fantastic to me triggered an interesting comment from a reader. A detailed response requires more elbow room than a comment allows, so here’s a follow-up article instead.
One of the points involved that our scientific ideas, no matter how inaccurate they may turn out to be, are at least based on evidence. And to the credit of science, when we recognize errors in our interpretation of the evidence, science changes to accommodate the new interpretation.
This has been, as I mentioned in that post, hugely successful. One of the failures of our spiritual metaphysics is that it clings to frameworks defined thousands of years ago and often stubbornly refuses to accommodate new information.

I’d planned to do this later, probably for Sideband #64, but in honor of my parents 64th wedding anniversary (2 parents, 64 years, okay!) this numerical rumination gets queue-bumped to now.
Just recently I wrote about 64-bit numbers and how 64 bits allows you to count to the (small, compared to where we’re going) number:
264 = 18,446,744,073,709,551,616
That’s 18 exabytes (or 18 giga-gigabyes). Just to put it into perspective, if we were counting seconds, it amounts to 584,942,417,355 years; more than 500 billion years! (That’s the American, short-scale billion.)

One of the things that strikes me about the idea of God is how universal that idea is. To the best of my knowledge, every society in every age has had some sort of spiritual core belief.
I used to state this as the assertion that every society believed in some sort of god or gods, but it was pointed out to me that Buddhists don’t actually have a god. They do have some metaphysical entities, and more importantly, Buddhism is certainly a belief in a metaphysical reality that transcends this one.
So the question is: if humans universally find themselves finding God(s), what does this mean?

A long, long time ago on a USENET far, far away, I was part of a debate that started with the idea that, even if we had disk drives with 64-bit addressing, people would still fill them up with videos, images and whatnot.
The idea grew from some of us old-timers reminiscing about our first brick-sized 5-meg hard drive and how we thought, “Gee, I’ll never fill that up!” (And look how that turned out; I have single image files that wouldn’t fit on that drive!)
The premise was that, even with seriously gigantic hard drives, we’d still manage to fill them and need more, more, more…

In an earlier post, I wrote that:
The problem for any honest theist is,
“What if it isn’t true?”
The problem for any honest atheist is,
“What if it is true?”
Ultimately both represent ways of looking at the universe. There is no factual conclusion, no proof, about either one; both are matters of faith and belief.
Science can argue all it wants that the Logic and Scientific Method is superior to believing in an ineffable reality but given all we do know and all we don’t know, in the end it is still just a worldview.

Nearly all science fiction fans share a meme about the number 42. This meme comes from the Douglas Adams book, The Hitchhiker’s Guide to the Galaxy, one of the great “modern classics” (an apparent oxymoron, but it is just shorthand for ‘a recent work that is so good that someday it will be counted among the classics’). The book is the first in the “increasingly misnamed” trilogy that shares its name.
The trilogy is “increasingly misnamed” in that it now has five books. The joke is that, in science fiction, trilogies are as common as aliens, spaceships and time travel. In fact, depending on the context, there are two trilogies that have easily earned the sobriquet, “The Trilogy.” (Issac Asimov‘s Foundation series in the context of pure SF; and, of course, J.R.R. Tolkien‘s Lord of the Rings books in the context of SF + fantasy.)
In any event, the number, 42, is the answer to the question.

Last time, I wrote about irony and the perverse universe. This time I want to write about something just as fundamental. It has the technical name, entropy, and there is a very technical definition that goes along with that name.
I’ll return to that later, but for now consider this simple truth: If you have a barrel of fine wine, and you add a teaspoon of sewage, now you have a barrel of sewage. On the other hand, if you have a barrel of sewage, and you add a teaspoon of wine, you do not have a barrel of wine.
You still have a barrel of sewage!

Sidebands are 10; a full hand; a (very small) odometer moment.
The accident of genetics and evolution that gives us ten fingers (and ten toes) causes us to count in tens and celebrate things that occur on tens boundaries.
Turning 30, 40 or 50 years of age is viewed as cause to bring out the black balloons and mocking birthday cards. Yet celebrating 30, 40, 50 or 60 years of marriage is cause to celebrate (especially these divorce-prone days).
