I'm still waiting for #Putin to bring #Russia's #Soviet-legacy population of militarized elderlly 1970s-era #psychics into play on #Ukraine, to try to "#manifest" #Zelensky's death by the power of wishful thinking.

It'd be about as effective and non-embarrassing as anything else he's tried.

Having read a lot of #Wolverine-centric #Marvel #Comics, I have to say I think "The Bubs" would be a good band name

By contrast, 2001's Discovery centrifugal habitat ring, thanks to being wholly contained within the pressure hull, was not different in any important way from having a hamster wheel in an Apollo command module. You could plan it in such a way that you could avoid the need for much in the way of crazy-robust and complicated couplings. A single -- admittedly probably pretty elaborate -- coaxial power and data link, some WiFi (1968 version) and simple package transfer of solids and liquids and you're all set. In principle.

(2001: A Space Odyssey got one thing right, at least: the rotating section was fully contained within the pressurised hull, so you didn't need to build and worry about atmospheric and life-support couplings. 2010 and The Martian, etc, didn't even have this mitigation.)

(If you're using solar collectors and your path isn't radial to the sun, then you don't want the solar collectors to be mounted to the rotating part either. But we've already established that you'll want some minimal nonrotating section with power and comm links, so that's covered.)

My current #SF movie bugbear: Non-rotating #spacecraft with a large rotating section for the human habitat. Bonus points if the habitable part spans both the rotating and non-rotating portions and the crew can move freely between them.

It's an absurdly complex #engineering challenge to build it this way, it introduces an open set of failure modes that would not otherwise exist and there's no good reason for any of it that I can think of.

Instead, rotate the whole ship, and if there are a few things which for some reason must not be rotated (scopes, antennae and cameras, perhaps?) place them in the smallest and simplest possible unpressurised nonrotating segment at the axis.

August 7th:
Feast day of Dometius of Persia and Donatus of Arezzo; in deference to vulgar practice now merged and observed as the feast of Dominos of Pizza. To those still groaning under the yoke of bitter servitude: if you're not delivered in 30 minutes, you're free.

@cherold (the age range is an idiosyncratic choice of my own, of course. 15 is about the earliest age with which I feel much connection to the popular music of the time, and 35 is about the point when I largely stopped feeling much one. Your mileage may vary. Not all stocks go up: some go down. Ask your doctor if highly subjective pop culture generalizations are right for you.)

@cherold We've both deleted our but I think you're missing a term in your algebraic expression. Let's try it as a story problem:

"Ed really likes a song that came out in 1982. What year was Ed born?"

Aa you see, unresolvable. I associate that particular song with people who'd have been somewhere between 15 and 35 or so in 1982, most of whose birthdates fall well inside the baby-boom period of 1946-64

In case you didn't know and were wondering, that latin text on your diploma simply authorizes you to speak with specious confidence about things entirely outside your area of study that you don't know anything about.

#NATO now has legitimate cause to defend all ports at the mouth of the #Danube. This is a vital corridor essential to trade, livelihoods, the safety and economic well-being of #Europe. #Russia attacking it is NOT just #Ukraine's problem: it is manifestly a direct attack on Europe.

If you can't rebut what they said, commit irrevocably to the belief that they said what you can rebut.
