As someone with almost literally a life-long love of astronomy (my first word was “star”), I’ve always been vaguely intrigued by astrology. I’m fascinated by that which endures through many ages and cultures of humanity. At the very least, such things reflect an aspect of human consciousness. They’re also a shared idea, so they form community in the like-minded.
Is there magic in the stars? No, not in the astrological sense. Any “magic” is in us, in our consciousness, not in the stars. (Worldwide, on average, almost 12 million babies are born each month. That an astrological sign applies to them all is a bit of a stretch.)
And the thing is, most of us aren’t the sign we think we are!
To advance, I’m gonna need another bit…
A different, more personal, anniversary… Looking back at the five years of this blog (or, for that matter, the many more years of this blogger), I can’t help but reflect on how man- and mice-plans go astray.
Case in point: Sidebands. Originally, as the name implies, meant as out-of-the-norm posts. True of the first few, but by #41 they’d become too inclusive, not much different from regular posts. The idea needed retooling; it was over a year before I posted #42. (And I added Brain Bubbles for minor-topic or very short posts.)
Since then, I’ve tried to restrict Sidebands to extremely technical topics. (For example, #59. I should have made that tesseract post #60, and today doubly wish I had.)

H.B. to an old friend. A long road winds from there to here.
It’s party time! Friday night, and everything’s right.
For your consideration, there’s celebration in the air (that’s no exaggeration). We’re talking ’bout elation; lookin’ for participation. Ya gotta feel the situation. Join with the recreation; enjoy the circulation (and the conversation).
Listen to that good vibration, trackin’ jubilation destination. Forget your reputation; forget your moderation; ain’t no humiliation (that’s a stipulation). There’s no registration, no identification authentication.
I’m sure it’s no revelation; fermentation fascination will bring inebriation (and hallucination). Hesitation just won’t do; you have an invitation! There is no limitation at this here presentation.
That was my narration; how ’bout a small ovation?
“Pick a number from 1 to 100.”
Today I’m thinking about the number: 57.
What can be said about the number fifty-seven?
It almost looks like it might be a prime number (due, I expect, to the five and the seven, both of which are prime). But it’s not prime (or in its prime). It’s divisible by 3, and that’s easy to see, because:
5 + 7 = 12; 1 + 2 = 3
That trick works for any number divisible by three. Just keep reducing the digits by adding them until you get a single digit. If that digit is divisible by 3 (3, 6 or 9), then the number can be divided by three. We could even have stopped at the 12, since that is also divisible by 3.
A similar trick works for numbers you can divide by 9 (which, of course, is 3 to the power of 3). Consider 101,745. Is it divisible by 9?
1 + 1 + 7 + 4 + 5 = 18; 1 + 8 = 9
Yes it is! (And any number divisible by 9 is also divisible by 3.)
