The Reality of Apollo / Apollo 13 doco on YT

« Last post by Peter B on April 22, 2025, 12:28:56 AM »

Just found this 2 hour video. It's an excellent piece of animation and explanation of Apollo 13, the mission, the accident, the recovery and the cause. I learned several things about the accident that I hadn't previously been aware of.

Highly recommended!

General Discussion / Radiation and Absorbed doses; further reading?

« Last post by TimberWolfAu on April 21, 2025, 12:40:29 AM »

Hi Folks,

I'm finding myself with no course to study at the moment, so, where is a good place to start for further understanding of radiation and absorbed doses? Along the lines of calculating, impacts of different materials etc

Figured I have the time, so I might as well deepen my understanding.

Sort-of related, there's a new video from Ellie In Space which goes into detail about just how bad things were on the Starliner as they approached the ISS, certainly far worse than I understood at the time.

I saw that - very good. I was able to understand!

I was impressed that my kids, 17YOS, 14YOS and 12YOD managed to keep up an indoor game of hide-and-seek for nearly half an hour on Sunday, and I said so to them.

12YOD: It only continued that long because I'm really good at the game.

14YOS: No, it's only because I'm really bad at the game.

BZ?

BZ = Bravo Zulu = Naval terminology / signal flags for "Well Done!"

Well I was a ground pounder so the term was unknown, thanks.

What was your first clue?
And we got another nearly four years of this circus, even if, IF, there's a peaceful transition of power.
Given his track record (Be wary, be wary of the 6th of January, of losers and MAGA and plot. I know of no reason why Capitol treason should ever be forgot) and repeatedly stated intentions to seek a third term, I definitely would not count on it.

Well, now we got a fun little trade war going on with you guys, eh?
That'll aboot bring down the price of eggs, fer sure, eh?
Gods, this timeline gets dumber and dumber with each day.

Well, at least most of Australia has largely escaped the worst of the new tariffs, at 10%. Australia's territory of Norfolk Island will instead cop a 29% tariff...which doesn't make a lot of sense seeing as it apparently doesn't export anything to the USA.

Making even less sense is specifically listing Heard and McDonald Islands for a 10% tariff. First, the islands are another Australian territory, so why bother listing them separately from Australia? Second, they're uninhabited...by humans anyway.

Seems they have their own internet domain ".hm". Same for the rest, looks like they just downloaded the list of TLDs and used that.
I don't think these guys have any idea what they are doing.

Never mind, I assume this 10 minute video explains what's going on...formula

Yes, that's what I was talking about. The interviewee James Suroweicki is the author of the Twitter thread, but the video explains it more smoothly. It does leave out the companion claim that this is the method that various LLM AIs spit out when you ask one to formulate a tariff policy. I'm not sure what if anything that proves. There's also the issue that the computation considers only trade deficits in goods, not in services. The U.S. runs a trade surplus with most countries for services.
