1/ "molten glass comes on two sides of a trough, overflows the trough, fuses below, and then just cools as a optically perfect sheet that’s a half-millimeter thick, the width of a king-size bed, and then a robot grabs it while it’s cooling and cuts it off."theverge.com/2021/8/31/2264…
2/ But I thought we ran out of new ideas in 1971! How can this be?

"the surface of the mirror is smooth to the level of one atom. If we pointed this system at the moon, right, when that beam of light got to the moon, it’d be like, I forget the exact number, 20 centimeters wide."
3/ This, you know, seems innovative!

"to get that extreme ultraviolet light, they vaporize tin, the metal, with a laser. And then when the vaporized tin is dropping, they hit the drops with another laser and it generates this plasma, which emits this extreme ultraviolet."
4/ What about total factor productivity? But mRNA seems innovative.

"In late ‘80s into the '90s the US government invested in genomics, the human genome program, biotechnology, molecular biology... And we had this wave of innovation which laid the foundation for mRNA vaccines."

1/ "Credit cards are a Neanderthal version of what really needs to happen...much more consumer transparency, much more consumer control, [a] really clear sense for what things cost, and when you’re done paying for them, even if you are paying over time." news.google.com/articles/CAIiE…
2/ "What we focus on is making sure that it’s really, really, really clear to you as you decide to use Affirm what the costs will be, what the term will be, that there are no late fees, that you don’t need to be scared about missing a payment. It’s our job to remind you."
3/ The consumer credit value chain is impacted by "buy now pay later." How much revenue is lost by other lenders? How much less do borrowers pay? Is there an underwriting arbitrage? Is scale a competitive advantage for "buy now pay later" providers?

The 70-degree Starlink shell will be populated with Falcon 9 launches Vandenberg in California. It will expand coverage to areas such as parts of Alaska and Northern Europe.

97.6-degree (polar coverage) and 53.2-degree shells will launch from Florida.

Satellite constellations link to the network of networks on Earth via a gateway. It isn't possible to have a gateway everywhere they are needed due to regulatory/licensing constraints and since so much of Earth is covered by oceans. Intersatellite links = fewer gateways needed.
3/ Shotwell on the economics of Starlink laser inter-satellite links: “Anything you add to that satellite is expensive, but when you pack 60 of them together and throw them on one reusable launch vehicle, the economics are pretty favorable for us.” satellitetoday.com/broadband/2021…

1/ What was the code name of the secret locked room where Microsoft kept the Macintosh prototypes it was testing, providing feedback on and building applications for prior to the Mac launch on 1-24-84?

Why is this t-shirt and motorcycle jacket related to that work at Microsoft!
2/ There are clues about the answers to the previous questions here.

The code name for the Mac at Microsoft was "SAND" but the article below was wrong about what it meant.
"At [the] time [Microsoft committed to the Macintosh] we decided our app strategy would be to emphasize the Macintosh and win there, then roll back to the PC when graphical interfaces become popular." Bill Gates

1/ "3-point shots have an expected value of about 1.1 overall with a slightly higher value in the corners, which are
closer to the basket."

Do you know what "expected value" means? If not, why not?

Expected Value of the book "Expectations Investing" is enormous.
2/ "Exhibit 2 shows that the expected value of 3-pointers was 14 percent higher than 2-pointers in the 2003/04 season. The natural way to arbitrage that expected value differential is to take more 3-point shots and fewer mid-range 2-point shots." morganstanley.com/im/publication…
3/ "Expectations investing recognizes that the key to achieving superior investment results is to begin by estimating the performance expectations embedded in the current stock price and then to correctly anticipate revisions in those expectations." expectationsinvesting.com/about-expectat…

1/ Rationing of hospital resources like beds and oxygen is happening now in Northern Idaho based on Crisis of Care. This means people needing care are scored to determine the likelihood they will survive. This applies to all patients (not just for Covid).
kivitv.com/news/what-is-c…
2/ "Normally health care is prioritized for the person who is worst off. Crisis standards change that. Instead, health care is provided to the patient most likely to survive. Someone who gets in a serious car accident scored the same as a COVID patient." idahostatesman.com/news/coronavir…
3/ "...about 90% are not vaccinated against COVID-19, he said. North Idaho’s Kootenai County has a COVID-19 vaccine rate of about 41% among those 12 and older. The statewide figure is 49%, while the national average is 62%." idahostatesman.com/news/coronavir…
