Today is my last day as Rio Americano's physics teacher. A road of 35 years comes to a close.
I have teased much of this, but I saved the best for last. It's not to be missed.
Going gentle into that good retirement? Not really my brand.

As I enter into Hour Three of @UPS “customer service” hold, I’m beginning to question my business choices.

The good people of @Lensrentals paid UPS for 3rd day delivery on 8/7. UPS got the package from Memphis to Denver on 8/8.
The package languished in Denver from 8/8 until 8/12. Resting on a shelf, collecting dust.
Maybe UPS workers negotiated 3-day weekends into their contracts.

Overseas customer service promised a call back from the local hub. You already know how that went: into the æther.

Called customer service, and now *I’m* in the æther. 1:30 into an estimated 25-minute wait.

Consequence-free rider stranding is clearly part of the @lyft business model.
Perhaps it’s built into the @Uber business model, too. @Uber_Support might be able to clarify.
Uber has yet to strand me on a scheduled and driver-accepted ride.

The genius of @DollarCars is that canceling a reservation on their website returns a “Something went wrong, try again later” message. So you call their toll-free number, only to be met with a “this line is not accepting calls” announcement.
Well played, @DollarCars.

This is a nice sim that scales from straightforward to “wait a minute!”. I wrote an activity for it. Link in the comments.
It's game time with Balancing Act! Students can solve puzzles while balancing
...Add an object to balance the plank, predict the direction when the supports are removed, or determine the mass of an unknown object. Try it out.

When NOVA's Decoding the Universe: Cosmos aired in May, I wondered if there were other "Decodings" in the works. It seems there were. At least one, anyway. Quantum. And I have questions.
