Catching Up

We've been over the mountain (Mt. Hood), my two daughters and I.  Alexia went earlier in her dad's late mom's Buick.  Sam, Tara's uncle, was in hospice, at Partners in Care in Bend, Oregon.

Last night, back in Portland, we visited Atlas Pizza, Tara and I, Patrick joining us.  Patrick has been contracted to dig down into command line Python minus any IDE.  A paying client likes it that way. He's using Wing's debugger in another class, a habit I'm likewise gradually acquiring.

I've completed a first Arduino course, a Coursera MOOC, and now I'm wading more deeply into that world of programmable circuits.  Tonight I'm teaching Python to adults, and next week to kids as well.  Mark me as firmly planted in tech.

However, American Literature (we might call it that) is on my mind, and I wonder about standards.  How much are able to build immune systems, as we might call them, if following a more German philosophy of bubbles, globes, foams.  To what extent will we stay prey, to "false news" in whatever guises?

Judy and I visited the funeral director while Alexia and Tara went on ahead. They ended up test driving a Ford Fiesta in Madras.  No memorial service has been scheduled yet; a way will open. This journey has been a part of it.  Remembering Sam is a new theme now, one I'll treasure.

Carol has done her share of road trips recently, both east and west, and flew the Blue House solo while we were gone.  Temperatures soared to record highs this weekend.  We're glad for the break in the heat wave, with overcast skies, now coasting in the seventies (Fahrenheit).

I've been showing Tara the latest PR around C6XTY, including my 4D logo in the mix, next to the link to Synchronofile.

Building Fractions

The code below shows a way of teaching operator overloading in Python.

Even though the standard library includes a Fraction type, it can't hurt to recreate it in a lesson, drawing on our knowledge of how fractions should behave.

Notice the embedded _gcd() method employs Euclid's Method to reduce fractions to lowest terms on initialization.  Since multiply and add operations, and their inverses, all end up creating new Q type instances (fractions), no attempt at reducing is made until then.

Hit the Run button to run the script.  Output appears at the bottom.

Uncle Lightfoot

Bill Lightfoot in 2010

At age 92, my uncle (dad's mom's sister's son) Bill Lightfoot has the baud rate to negotiate Amtrak on his own.  He escapes his comfy quarters in Seattle to be with his grand nephew.  He's eager for pictures of Jack, my dad.  They weren't much together after their chance meetup in Alaska, in the summer of 1947 I think it was.

Jack studied International Relations in DC, then went into regional planning under Dick Meier at the University of Chicago. After a strong on ramp performance, stateside, practicing planning in Portland, he went to nation-state scale, where you're looking at zoning and freeways, big picture infrastructure, less at individual housing or office complexes.  The latter is architecture and city planning, and more detailed.

I brought along some C6XTY as I'm timing myself to build a tetrahedron with four of them.  By "them" I mean soccer ball looking things, each assembled from six identical plastic parts, hence the name. The hexapent C60 is a meme, and a chemical (a carbon allotrope, a family of cages, then come the tubes and of course graphene, full circle, graphite, diamond and plain old soot -- carbon powder -- being the earlier discoveries).

Carol was also routing through downtown this same afternoon, and it worked to drop her at 10th and Taylor, park in a garage, observe some Flag Day childrens performance (a traveling troupe), then retrieve the car and head to Union Station, where the Coast Starlight has just arrived.  Bill and I headed over to Ringlers, where we enjoyed the usual great food and service (I'm a loyal customer). Thank you Bill, for making these forays.  I'll get you some more pictures, of dad.

This was the "short format" visit where we cut it pretty close.  The Coast Starlight is often late, getting here from California, but today was right on time.  I had Bill back at the station with only minutes to spare, whereas on another occasion we waited some hours.

On his previous visit he did "long format", coming a train earlier and leaving a train later.  That gave us time for Pittock Mansion, Kell's for lunch, visiting with Carol at Bagdad out my way, with time to spare getting back.  That was pretty exhausting though, for a ninety-two year old.  Did we get many pictures of Bill with his Aztecs (those were cars many considered rather funny looking, Bill loved 'em)?

Howard and Wilma came with Bill on one of these outings.  Bill and Barbara Hancock on another.  Amtrak:  keeping families together.  Bill wore his Northern Pacific hat.

OR Welcomes PR


Some will say it's a bit preemptive for a former territory, Oregon, to welcome Puerto Rico to the Union, as 51st state.

After some hundred years, I'm glad we have that sorted out.

Welcome.

Fundraising Dinner


Carol (mom) and I are about to drive across the river, against traffic (meaning with a faster trip time), for a dinner with Physicians for Social Responsibility.  As a veteran WILPFer, she's worked with the Oregon PSR rather closely, most especially on the Hiroshima - Nagasaki commemoration event, a time to pledge never again to indulge in nuclear war.

Since WW2, the planet has endured several nuclear catastrophes, beginning with so-called "testing", which irreparably harmed the ecosystem, followed by nuclear meltdowns. The meltdown in Chernobyl was such that brave and selfless human intervention was possible.

A tunnel was dug in record time to intercept the melting mass before it reached the water table.  In the case of Fukushima, human bravery is irrelevant and the Pacific Ocean is becoming increasingly contaminated, and by extension the planet.

The responsible jobs, going forward, have to do with cleanup and disaster mitigation. Humans floating around on military ships, threatening each other, saber rattling, is a lot of toy story nonsense wherein humans refuse to grow out of their kindergarten stage.

We'll have to leave them to play those war games, as they insist, and have the weapons to stop us from stopping them, but we don't have to treat them as mature adults.

I think a lot of the slowness to respond is about theater (the T in PATH).  People used to think Kings (a few Queens) had divine powers. Even when that illusion exploded, politicians managed to keep up an illusion of being in control.

That these people actually do any real work is becoming less apparent.  But then "work" in its physics meaning simply means "to expend energy" which we all do, of necessity, just to breath.  Any meaning beyond that tends to be tinged by moralizing, with Protestants (Christians known for their protesting attitude) among the first to chime in.

I need a haircut.  My gray hair is bushy and I'm wearing a maroon turtle neck with not such fancy pants. I'm in the ballpark of "frumpy academic" I suppose, though I'm closer to a Quaker crime boss (it's considered traitorous to laugh at politicians is it not?).  I've been posting to Forum 206 quite a bit. Does that make me a math teacher?

Sam Lanahan was by today with a truck load of C6XTY.  I'll be able to organize workflows for kids, having them construct soccer ball looking things from six curved pieces held together with eight screws. Then come the arms, suitable for interconnecting them in a lattice.

What's all this for?  Do you know what the isotropic vector matrix (IVM) is?  Octet truss?  CCP?  FCC (no not the government acronym).  Maybe we're just sharing some memes at first, basic STEM.

It'll be awhile longer before humanity grows up.  We're a work in progress.

Some of us don't think we need to learn about hard stuff, like science and math, as long as we have our politician parents to take care of us.  They'll protect us from the laws of physics, right?
