Searching for contentment
This is what fascinates me most in existence:
the peculiar necessity of imagining what is, in fact, real.

Tyson Yunkaporta, Sand Talk
How Indigenous Thinking Can Save the World
Really interesting book. It has inspired me to stop and look at several things from what is, for me, an entirely new perspective, which is something I appreciate.
Granted, there is much that Yunkaporta discusses—or yarns about—that I don't fully understand; how could I coming from my lifelong immersion in a low-context or field-independent print-based culture. But that doesn't diminish the perspective-expanding gift that this book is. Hopefully over time my understanding will expand and more of what Yunkaporta shares in this book will become available to my conscious and subconscious journey through this life.

"Imagine your smartphone knew everything about the city—but the city didn't know anything about you. Wouldn't that be truly 'smart'?"
Illustration from Cory Doctorow's related Jan 17, 2020 Boing Boing post:
Imagining a "smart city" that treats you as a sensor, not a thing to be sensed⩘
An excellent article by Cory Doctorow about his vision of how a smart city could be designed to work on behalf of its residents instead of its corporate and governmental overlords; a vision in sharp contrast to the privacy horror show that is unfolding as Google's Sidewalk Labs designs its Quayside smart city in Toronto.
As is so often the case with technology, the most important consideration isn't what the technology does: it's who the technology does it to, and who it does it for.
If we decide to treat people as sensors, and not as things to be sensed—if we observe Kant's injunction that humans should be "treated as an end in themselves and not as a means to something else"—then we can modify the smart city to gather information about the things and share that information with the people.

There doesn't seem to be any normal to the weather anymore. Fortunately, though, we've had a good bit of snow so far this winter (in our area, we depend on the winter snowpack for our next summer's water supply). One snowfall in mid-December dropped 26″ of dense snow overnight. Sure was beautiful when the sun rose the next morning, though it took us two days to shovel out from that one! I took this two days later when we finally were able to drive down to the mailboxes at the bottom of our neighborhood.

who has inspired me to look at design more deeply
and to take even more care about precision.
Although I'm still relatively new to the universe of amateur radio, I've already enjoyed enough interesting learning experiences as well as stubbed my toes enough times to have gained a few insights that I think are worth sharing.
I'm writing these notes as my way to keep track of what I'm learning (and also just for fun, as I love writing as much as learning). Basically, this is a collection of info I wish I had found online when I was browsing for insights: AmateurRadioNotes.com⩘ .
Sharks kill an average of 10 people per year. People kill around 100,000,000 sharks per year 1. People also kill approximately 425,000 people per year, topped only by mosquitoes, which kill about 725,000 people per year 2.
And we worry about sharks?

People walk at an average pace of about 2.5 miles per hour.
Meanwhile, light travels about 186,000 miles per second, or about 11,160,000 miles per hour. It would take light about 0.13 seconds to travel around the Earth,
1.3 seconds to travel the 238,900 miles from the moon to the Earth,
8.3 minutes to travel the 93,000,000 miles from the sun to Earth, and 1.3 hours to travel the 890,000,000 miles from the sun to Saturn. To get a glimpse of an idea of just how far away Saturn is, see If the Moon were only 1 pixel⩘ by Josh Worth.
At the scale of the solar system, the Earth is a spec of dust. 1,300,000 Earths could fit within our sun.
Our sun, as big as it is, is just a tiny twinkle of light in a suburb of the Milky Way galaxy. Its light takes 28,000 years to travel to the center of the Milky Way.
One light year is just short of six trillion miles (5,878,625,000,000). The Milky Way has a diameter of about 100,000 light-years, and contains as many as 400 billion stars, which together create a smidgen of light in our local group of galaxies.
The light of the Milky Way takes about 2,300,000 years to travel just to the nearby Andromeda galaxy. Isn't it amazing that by using our inherent art of visualization, we can be there, instantly, in this moment.
The observable universe is estimated to contain as many as two trillion galaxies. To get more perspective on this eXtreme Deep Field (XDF) Hubble image, see the short video: Hubble Legacy Field Zoom-Out⩘ . Make sure to read the notes, too.
To get a glimpse of an idea of just how big the observable universe is, see Neal Agarwal's fun website, The Size of Space⩘ .
And we worry about anything?
By the way, because of the Earth's spin, if you're standing still at the equator, you're actually moving at about 1,667 km/hour (1,037 miles/hour). The Earth is orbiting our sun at approximately 30 km/sec (67,108 miles/hour). Our sun is orbiting the center of our Milky Way Galaxy at approximately 250 km/sec (560,000 miles/hour). And our galaxy is moving through our universe at approximately 600 km/sec (1,340,000 miles/hour). Don't blink!
All distances and times are approximate.
