Watched the entire video. A greatly dispiriting example of regulatory capture. Not only does Boeing appear to own the FAA, it's bought off the DoJ as well. Thank you for posting the video link.

I agree. My wife and I are facing the transition to a fixed income. We'll move to less expensive digs soon, in a rural area. We're both on Macs & iPhones. I'm worried about data charges for MacOS & iOS updates. No cle

I think helium is used for its low kinematic viscosity. That lets the R/W head fly closer than, for example, air. The other inert gases (Ar, Ne, etc.) have KV values higher than air and would give no advantage. He is better for therma

My one memory of the Sacramento Fry's is buying a 5 lb GummiBear to prank a friend. Not 5 lbs of GummiBears, a single 5 lb GummiBear. Sorry to see the stores close.

IIUC, this says there are nuclear excitation states that can be selectively and controllably pumped with X-rays. Any chance of creating a population inversion for lasing action? (Or whatever it would be called at nuclear energies/wavel

CO2 will acidify the wine, which might well alter its taste. Carbonation (in the sense of making the wine fizzy) will not happen unless pressure is used to drive the CO2 into the wine. You need a supersaturated CO2 solution to get fizzies.

Two years ago, my wife and I visited the Israel Museum in Tel Aviv. We were on our way out when I saw a door that branched to a room of "deep antiquities", or words to that effect. One of the exhibits consisted of three gold brace

As an old guy, I feel the same way. I was in JPL’s SFOF building watching Armstrong and Aldrin step out onto the moon. Today’s SN8 mission gave me reasonable hope I’ll live to see somebody set foot on Mars. It’s been a good day.

Treatment resistant depressive here. After three decades of trying different therapeutic treatment avenues, including many pharma and non-pharma options, I think that refractory (treatment resistant) depression is a phenomenon rooted in bio

I'll second the "do not be afraid". At my first, I was offered the option of minimal sedation, which I took. Then my doc offered to put up an extra monitor so I could take the tour, as it were. It was fascinating. By now, I&#

Really think these would be helpful: 1. Demilitarize police 2. Make police disciplinary and complaint records public 3. Eliminate qualified immunity for police These would be a good starting point.

Could alternate laser colors: green for front legs, red for back. Tailoring molecules for specific wavelength response is old tech.

Consider getting an extra car. Not universally applicable, but we have one more car than we use. So there's always a car in our driveway, lending an appearance of occupancy. Not sure it's any better than an ADT sign, but maybe jus

An old name for lead acetate is "sugar of lead". Guess they needed to sweeten their wine.

It'll be hard to not publicize the LZ. NOTAMS (aircraft exclusion zone) and maritime exclusion zones are public documents. They're essentially map coordinates for the LZ. I think you're right about there being some CG vessels

I got my current (very well-paid) gig from a cold call from my LinkedIn account. That said, I agree with your view. I feel like taking a shower after each monthly login.

Nobody's making that assumption. It's a hypothesis. All evidence we have is consistent with a "world being present before living beings inhabited it". Therefore the hypothesis is not disproved, which is all science ultim

One of the curious consequences of the polywater episode was delayed development of diamond synthesis under metastable conditions, mainly by chemical vapor deposition. After polywater, Deryagin was a very early claimant to having produced d

>But not wanting to die __ever__ can be driven by narcissism. Couldn't it also be driven by deep, abiding curiosity? This seems to me at least as likely as narcissism as a motivation.

Your FB feed results don't seem impossible. First CV-19 death in CA was Feb 6 [1]. That's presumably at least a couple of weeks after infection. [1] https://www.nytimes.com/2020/04/22/us/coronav

Has anybody looked at station-keeping issues (briefly searched, found nothing)? A space based solar power array is a large solar sail. As it orbits, its angle of incidence to the solar wind will change, perturbing its orbit. Lightsail 2 [1]

>In other words, when you recover from covid-19, you are immune to it. Probably not. It seems [1] that in humans and animals, there's no long-term immunity arising from infection. [1] https://www.quantamagazine.org/
