Information Systems

Last time I explored five physical systems. This time I want to implement those five systems as information systems, by which I mean numeric versions of those five systems. The requirement is that everything has to be done with numbers and simple manipulations of numbers.

Of course, to be useful, some parts of the system need to interact with the physical world, so, in terms of their primary information, these systems convert physical inputs into numbers and convert numbers into physical outputs.

Our goal is for the numeric systems to fully replace the physical systems.

Causal Systems

Recently, I’ve been involved in some discussions about causality, and some of those discussions have struggled to find any resolution, which I find frustrating. I don’t think people need to agree on ideas, but my experience is that usually people can agree on how to frame and talk about those ideas.

I sometimes get the feeling people are so set on disagreeing that they don’t always engage on what the other party is saying. I never know if it’s a lack of comprehension, a lack of willingness, or (on my part) a lack of communication skill or sufficient explanation.

So here are some things I think (I hope) are uncontroversial.

Whadda Week!

The culprit!

Well, it’s been quite a week! As mentioned in the last post, the coming of fall (which is always bittersweet for me), a bout of miserably muggy weather, and then electrical problems in my home, have all conspired to batter the shores of my equilibrium. But there have been some raisins in the poo pile. This week, stressful though it was, has turned out a good one.

For one, my Minnesota Twins won the AL Central Division last Wednesday! They are going to postseason for the first time since 2010. (The bad news is that it looks like they’ll face the Yankees — who ended the Twins’ postseason in 2003, 2004, 2009, 2010 and 2017.)

And my electrical power problems are fixed. (I think.)

Scenes From a Walk

Enjoying a nice morning!

I’ve definitely been feeling the wear and tear of my age lately. This past few weeks, especially, a variety of things has conspired to do considerable pounding on my emotional balance. Simply put, it’s been a shitty transition into fall with the looming dark and cold of winter (the Autumnal Equinox was this past Monday).

And since I have an electrician coming tomorrow to try to solve the power outages that have affected half the circuits in my home, it ain’t over yet. On the other hand, counting blessings, the weather is finally fall-like (we had a bout of hot muggy misery last week); I’ve been really enjoying my morning walks; and I read one of the most delightful and brilliant science fiction books.

I’ll tell you about the book this coming Sci-Fi Saturday. Today I thought I’d show you why I love my morning walks!

BB #63: In the News

Time for another Friday News Dump! The good news is that these are about quite recent news articles that caught my eye. (The bad news is that I might dump some older ones on you if there’s room.)

Usually I present them, more-or-less, in order of their interest to me… and apparently to my readers, since the comments seem to always involve the first article. So this time I’m going to save the meatier one (in my eyes) for last hoping the others get some interest.

So the lineup is: Dog brains, static electricity, quantum DNA, and free will.

The Differential

e-fence-1

Zzzzzzzzzzz-t!

One of those annoying-to-those-who-know-better shortcuts that movies and TV shows sometimes take is the visual trope of throwing a piece of wood (or a rock) at an “electrified fence” and producing an exciting shower of sparks. Typically, one character is just about to touch the fence, only to be pulled back just in time by another character who throws something at the fence to show the first character how they almost bought it.

It looks good — everyone loves a good sparking. In fact, you may have noticed how many action scenes take place in factories that seem mainly to manufacture sparks and steam. You may have noticed how often welders seem to be creating showers of sparks in the background of every action movie.

But this isn’t about our love of sparks.
