That sounds sub-optimal. Mostly I'm just using light rail to go to/from the airport when I'm in Seattle, so I'd not noticed that quirk.

You can get an ORCA card and it works on all of these. I'm not sure on how the end-to-end fare works these days, though.

Iran Join Rick as he explores the most surprising and fascinating land he's ever visited: Iran. In a one-hour, ground-breaking travel special on public television, you'll discover the splendid monuments of...

In the spring of 2008, I feared America was on the verge of war with Iran β€” and, believing that it’s good style to get to know people before you bomb them, I made β€œRick Steves’ Iran,” a one-hour special that could (and would) only debut on PBS. Sadly, this special has become pertinent again today.

I think a 4. Slightly worse that "mid".

Semi-related: In college I ran into one of my maths professor post final and he cheerily said that I did <Scottish accent>"Amazingly satisfactorily."</Scottish accent>
I'd no idea what that meant until I got my grades (it was positive).

I avoided putting the final total anywhere on the paper to make it easier for students to dig in and discuss with one another with out the letter-status so front and center. (I also didn't post the grades till the end of the day so kiddos didn't come to class having already looked)

Oh yeah! Ground News is also fascinating since they'll show how different sources position the same story. Reading the headline differences is wild.

I've been following Jessica Yellin, who does News Not Noise, on substack and insta for national coverage. A friend of mine started getting the local paper and recommends it and I found a local indie news source on substack, but ymmv depending on locale.

Students also formalize the notion of a transformation as a function
from the plane to itself. When the transformation is a rigid motion (a translation, rotation, or reflection) it is useful to represent
it using transparencies because two copies of the plane are represented,
one by the piece of paper and one by the transparency.
These correspond to the domain and range of the transformation,
and emphasize that the transformation acts on the entire plane, taking
each point to another point. The fact that rigid motions preserve
distance and angle is clearly represented because the transparency
is not torn or distorted.

Initially, students view rigid motions as operations on figures
(β€œtransformations in the plane”). Later, students come to understand
that it is not the figure that is translated, rotated, or reflected, it is the
plane that is moved, carrying the figure along with it. Students start
thinking, not of moving one figure onto another, but of moving the
plane so that the first figure lands on the second (β€œtransformations
of the plane”) without moving the coordinate grid. This change in
perspective is makes it possible to describe the effect of a given
rigid motion on any point in the plane.

I'd be interested for a take on this from topology or differential geometry. There is something odd with these nuances, but I don't know the right question to ask to get at the distinction. And I know some folks say the plane is just a reference and it's the object that moves.

new question: are those two sets of instructions actually different when both involve coordinates, which implies both are on a coordinate plane?

I feel the same. "transforming figures" feels more "low floor" to me while a transformation of the plane is like a function F that takes each point P to a point F(P). I've yet to find a straightforward way to think about the delta between these ideas, though

I read the 2nd instructions as getting the same result as the 1st instructions were they for, say, a grade 8 student. Sounds like you are thinking about transformations as movements of figures vs transformations as functions from the plane to itself?

I say they are the same since the center of rotation is based on the figure and not the plane. I did not calculation, but played with objects on my desk to think it through. east-->north-->pivot = pivot-->east-->north

I want to provide some context on what that means and why it matters.

Should be plenty of sidewalks. That's not far from the Music hall and main convention center. Oh yeah, there's an Estrella Bakery right at the Inn! Nice.

Tucson Museum of Art is nice and there are several art and history galleries near it. The Tram or a short lyft can take you from downtown out to Mercado San Agustin and the MSA Annex. Lots of local art. Seis Kitchen is solid and La Estrella Bakery for Mexican pastries
