Most of the remnants of “the gang” went to see Peter Gabriel at the Xcel Energy Center in St. Paul last night. As they say, a (very) good time was had by all. It was the sort of enjoyable (and energetic) night that keeps you smiling to yourself for days. I do so love live music.
And, wow, does Gabriel (at 73!) put on a show worth seeing and hearing. Some rockers haven’t aged well, but Gabriel continues to find new visual and musical expression. Last night was as memorable as any of his previous shows.
I don’t have a lot to say — still basking in the afterglow — but I do have pictures.

Whatever you think about Tom Cruise the person, it’s hard to dispute that Tom Cruise the actor has turned out a lot of very worthwhile films. It’s hard to find many duds in his filmography but easy to spot noteworthy titles. Ever since Risky Business (1983) and Top Gun (1986), Tom Cruise has starred in movies so memorable that they became part of our cultural lingo.
More importantly for this Sci-Fi Saturday post, Tom Cruise has appeared in a perhaps surprising number of science fiction movies. Even more importantly, nearly all of them are good science fiction movies. Some of them are even really good.
Unfortunately, one of his rare duds is among them.

It occurred to me that, to some extent, I’d like my most of my blog posts to be like these Friday Notes posts: extemporaneous ramblings and the setting free of any notes recently captured. And some old stories (and maybe a few pictures).
It’s not that I want to stop ‘splaining stuff, my inner teacher is strong. (Is it man-splaining if you’re a teacher?) It’s been one of my things since grade school. Spead knowledge!
But the rambling sure is easy. And fun!

It’s been a while, but the two previous posts in this series (this one and this one) explored the mechanism behind partial differential equations that equate the time derivative (the rate of change), with the second spatial derivative (the field curvature). The result pulls exceptions to the average back to the average in proportion to how exceptional they are.
Such equalities appear in many classical physics equations where they have clear physical meaning. Heat diffusion (explored in the previous posts) is a good example.
In quantum mechanics, they also appear in the Schrödinger Equation.

Another (very) late edition and in the same week [see previous post]. In this case, it’s because I hadn’t planned a Friday Notes post for today, but I’ve gotten so indolent lately that I’m falling out of the habit of blogging. (Or, the eternal question, have I perhaps gotten weary of it?)
But, as polite people say, “Stuff happens.” And because it does, I have enough perishable notes that I may have to put out two Notes editions this month.
Assuming I can get back in the blogging habit.

A late edition Mystery Monday post because I’ve been distracted by various and sundry. I’ve meant this for more than one previous Monday. Not gonna miss another.
Having pretty thoroughly explored the British Queens of Crime as well as (the American) Ellery Queen, I’ve turned to new pastures: the Butch Karp / Marlene Ciampi stories by Robert K. Tanenbaum and the Matthew Scudder stories by Lawrence Block. And French author Maurice Lablanc!
Plus, I’m disgruntled by Dark Winds, an AMC TV series that (too loosely, IMO) adapts two novels from the Navajo Tribal Police series by Tony Hillerman.

Long ago (in the first year of this blog), I posted Sideband #34: The North Star, which was about how sighting on the North Star (Polaris) gives you your latitude. Simply put, the elevation of the star is your latitude. My Twin Cities are at 45° north, so Polaris is 45° above my northern horizon. Simple!
In this Sideband, I’ll explain how you can use your wristwatch as a compass. Assuming your watch is an analog one with hands. And assuming you can see the Sun (so this doesn’t work at night).
But, unlike North Star navigation, this one does work in the southern hemisphere.

Mathematician and educator John Baez has been putting out an excellent series of posts about music theory on his blog. The most recent, the seventh, is about how you can generate scales by picking out piano notes in intervals of fifths. What’s interesting is that you can generate all seven major scale modes in each of the twelve keys (a total of 84 scales).
It’s very cool (and new to me how this works out), and John asked if any of his readers would be interested in creating a table of all 84 rows. That’s exactly the sort of little project that often catches my eye.
A new and different problem to solve!

We’re about to enter a new phase of Friday Notes. I’ve cleared most of the primary pile of notes for blog posts. What remains are notes that still might lead to posts if I find the motivation. There is also a thick sheaf of much older more ambitious notes, most of which are probably past their Use-By date by now.
The destiny of that thick sheaf remains to be seen, but I recently dug out an even older set of notes. Two old spiral-bound half-sized notebooks… from the late 1970s and early 1980s! One contains thoughts and ideas, the other fragments of song lyrics.
I haven’t looked at this stuff in years. Going through it, I decided to record some of the more interesting in blog posts before I toss those notebooks.
