As people age, especially later in life, most report that time seems to pass faster. That is certainly true in my case — Mondays I often find myself surprised that it’s already laundry day again. Friends my age report the same thing; the weeks, months, and years, seem to pass at an ever faster rate.
My theory was it’s mainly due to percentages. At ten years old a year is 10% of a lifetime, but at 60 years old it’s just 1.666%.
Recently, a friend of mine floated an interesting alternate theory.
This is the third post of a series exploring the duality I perceive in digital computation systems. In the first post I introduced the “mind stacks” — two parallel hierarchies of levels, one leading up to the human brain and mind, the other leading up to a digital computer and a putative computation of mind.
In the second post I began to explore in detail the level of the second stack, labeled Computer, in terms of the causal gap between the physical hardware and the abstract software. This gap, or dualism, is in sharp contrast to other physical systems that can, under a broad definition of “computation,” be said to compute something.
In this post I’ll continue, and hopefully finish, that exploration.
My first thought was to call this “Baseball Blues”, but that title didn’t fit, because I’m not particularly blue about it — whether that means depressed, naughty, or playing the. Nor did I intend any reference to an old, often pejoratively used, slang term for baseball umpires. As in, “Hey, Blue! Ya blind?! That pitch was way outside!”
What I am feeling about baseball, though, is decidedly blah, which is weird because after years of being very awful, my Minnesota Twins have had some good seasons and at long last become contenders. After some of the worst seasons in franchise history, that’s rewarding to see.
So why is it that I just don’t care?
Fans of Doctor Who, at least those without an unreasoning dislike of Jodie Whittaker, may get a kick out of seeing her in the 2011 British alien invasion film Attack the Block. It’s a small rather unregarded film with a box office return of only half its £8 million budget (about $11 million USD at 2021 rates). Since its release it has gotten well-deserved critical praise and won a few international accolades.
I should note that Whittaker is not the lead. At best, she’s a co-star, and perhaps almost more of a major supporting character (she is present for most of the film). The film stars John Boyega, who many will know as Finn from the final Star Wars trilogy.
I highly recommend it for all science fiction movie fans.
Digital Computer
In the previous post I introduced the “mind stacks” — two essentially parallel hierarchies of organization (or maybe “zoom level” is a more apt term) — and the premise of a causal disconnect in the block labeled Computer. In this post I’ll pick up where I left off and discuss that disconnect in detail.
A key point involves what we mean by digital computation — as opposed to more informal, or even speculative, notions sometimes used to expand the meaning of computation. The question is whether digital computing is significantly different from these.
The goal of these posts is to demonstrate that it is.
Nurses are awesome!
For most of my life I’ve claimed I’m not someone who gets bored. I have too many interests to ever be bored in the usual sense, and there is always new territory to explore. I love trying new restaurants, new authors, and new TV shows.
The Yin to that Yang are the beloved favorites I visit again and again. There are eateries I frequent and authors I re-read. In part because there are menus to explore (and which change) and words and ideas that take repetition to fully understand and appreciate.
But I tend not to re-watch TV shows except in some special cases.
Time for another round of notes — bits and pieces too small for a post and which, for whatever reason, don’t seem likely to ever grow into a post (or even a Brain Bubble con carne). Best of all, from the perspective of many readers, not one single shred of math or contentious ideas!
These notes posts generally have an undercurrent of “spring cleaning” — the whole idea is to help reduce my ever-growing pile of scraps of paper with half-baked ideas. Actual spring cleaning is upon us, so I’m even more vested in seeing how much I can clear away. I even have some notes devoted to the very idea itself.
So without further ado…
The Age of Fire is a key milestone for a would-be technological civilization. Fire is a dividing line, a technology that gave us far more effectiveness. Fire provides heat, light, cooking, defense, fire-hardened wood and clay, and eventually metallurgy.
The Age of the Electron is another key technological milestone. Electricity provides heat and light without fire’s dangers and difficulties, it drives motors, and enables long-distance communication. It leads to an incredible array of technologies.
The Age of the Algorithm is just as much of a game-changer.
When I was in high school, bras were of great interest to me — mostly in regards to trying to remove them from my girlfriends. That was my errant youth and it slightly tickles my sense of the absurd that they’ve once again become a topic of interest, although in this case it’s a whole other kind of bra.
These days it’s all about Paul Dirac’s useful Bra-Ket notation, which is used throughout quantum mechanics. I’ve used it a bit in this series, and I thought it was high time to dig into the details.
Understanding them is one of the many important steps to climb.
Today is the first Earth-Solar event of 2021 — the Vernal Equinox. It happened early in the USA: 5:37 AM on the east coast, 2:37 AM on the west coast. Here in Minnesota, it happened at 4:37 AM. It marks the first official day of Spring — time to switch from winter coats to lighter jackets!
Have you ever thought the Solstices seem more static than the Equinoxes? The Winter Solstice particularly, awaiting the sun’s return, does it seem like the change in sunrise and sunset time seems stalled?
If you have, you’re not wrong. Here’s why…
