We make a lot of sausage in meetings. Brainstorm ideas and figure out what the challenges will be. Having all five or six people there at once is much more efficient than taking back the forth to each one individually.

There are status update meetings, but those are so other people know what you’re doing so if it effects them they can work with it.

It’d need to be 13 to 80 times more massive to be a brown dwarf.

en.m.wikipedia.org/wiki/Brown_dwarf

If it gained mass rapidly, most all the moons would likely destabilize since they’d have way too little velocity for the orbit they’d now be in. But if they sped up to accommodate, it’d depend on the density change of Jupiter. The fusion would push out material a bit, but the density would probably just increase because of the increased mass.

But if the density stayed the same, the radius would be 2.4 to 4.3 times larger than currently. With Jupiter having a radius of 70,000 km, that’d put it at 170,000 to 300,000 km radius. That’d put Metis and Adrastea inside 170, and Amalthea and Thebe inside 300. They’d already be heavily inside the jovian atmosphere, so they’d be toast. Io, Europa, and maybe others might also fall due to higher atmospheric drag at those levels.

I think the rest of the moons would be planets then, and the solar system would be a binary system.

Remember, refineries are the bottleneck not the wells and pipelines. So targeting it all on refineries has the highest impact to production.

Donating to United24 hopefully helps if you can’t volunteer yourself. Does anyone have info on how to donate to Ukraine anti oil more specifically?

“Everyone needs to agree with me more”

Probably more effective to give to a food pantry to avoid the corporate profit cut, but the thought is very nice.

JohnDClay ,

I thought they’d be ordering online and paying in advance. But if not, sounds okay

JohnDClay ,

Okay cool, I thought they were ordering online and pre paying.

You only need a graphing calculator because you’re not allowed to use wolfram alpha, desmos, or Matlab. Since you’re mandated to use graphing calculators, (sometimes even specific models) there’s no incentive to make them cheaper or better since you need to buy them anyway.

JohnDClay ,

I used my mom’s graphing calculator without issue.

JohnDClay ,

Yup, free market only incentives competition when it’s actually free. Demand monopolys are just as bad as supply ones.

JohnDClay ,

My friends with a lot of kids got a used airport limousine. I guess it was cheaper than an express van at the time. That was pretty cool and unique.

JohnDClay ,

No they fired him, but he’s staying on till they find a replacement. (He did get millions of dollars to boot though)

JohnDClay ,

The speed varies slightly depending on your speed and proximity to massive objects!

SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.

Magnesium comes to mind that would be light but expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides?

JohnDClay ,

About 48 tons of meteorites enter the atmosphere every day. I couldn’t find the elemental distribution, but I’d guess there is some aluminum in there. How much of an increase is 14 tons aluminum per year over the many tons of aluminum entering the atmosphere already? That might be good to get a rough estimate of how impactful this is.

JohnDClay ,

Wood is interesting, but the article doesn’t address off gassing at all, which is a huge problem for communication satellites. Is there a way to keep the wood from off gassing? For 3d prints in vacuum, they metal coat them to keep the gas inside. Or maybe you could resin soak them? With hopefully an extremely UV stable resin. But I didn’t know what the weight trade looks like then, resin is heavy.

But if you’re looking composites anyway, carbon fiber would be another great option. Lightweight but with a few manufacturing constraints. But should burn up to carbon dioxide on reentry.

JohnDClay ,

Yeah you’d need to put up fewer sats per launch. But they might still have enough lift capacity on starship to do that.

JohnDClay ,

48 tons per day, so it’d need to be less than 0.08% aluminum to double it.

JohnDClay ,

4.8kg per day gives 1.75 tons per year, giving an 800% increase. That’s still really big, thanks for tracking down the numbers.

JohnDClay ,

The boomers are always on active alert, so would standby be a step down? I didn’t get what this would do. Everything is already ready to launch quickly and has been for decades.

House Republicans Propose Renaming Oceans After Donald Trump (dailyboulder.com)

House Republicans have ignited a firestorm with a proposed bill that would rename the vast coastal waters encircling the United States after former President Donald Trump. The legislation, spearheaded by Florida Representative Greg Steube, seeks to rebrand the US Exclusive Economic Zone as the “Donald John Trump Exclusive...

JohnDClay ,

Have any countries named their EEZs?

JohnDClay ,

WTF! That’s too far!

JohnDClay ,

And the depth of focus is incredible!

JohnDClay ,

Plus rich people can better afford quality stuff made in the USA.

JohnDClay ,

But right now the cheap stuff is made overseas like in Asia. The expanse stuff is built in Europe or the US. Tariffs would likely be harsher on Asia products. So expensive stuff might not get much more expensive at all. The cheap stuff would get much more expensive.

Meaning there’d be a bigger cost percentage increase for the people who already can’t afford it. A double whammy.

JohnDClay ,

Not what I understood from it but okay. I thought you were saying rich people are better able to absorb the cost increase. I was saying the cost increase would also be less for rich people.

JohnDClay ,

If you say so

JohnDClay ,

Wolves are apex predators. Or were till we turned them into poodles.

JohnDClay ,

They’re referring to Tesla right? They replaced chrome with black a while ago.

JohnDClay ,

Plus Russia doesn’t even control all of the regions they’ve annexed. This is asking Ukraine to give up more territory than Russia has occupied and agree to never join NATO for noting in return.

JohnDClay ,

Yeah so why should Russia dictate the terms?

JohnDClay ,

Really? Seems to me like they were trying to capture kiev and depose the government and quickly set up one friendly to them. You think that’s happened?

JohnDClay ,

This memorandum would be just at much of a joke, I’m for Russia will write or argue in such a way to make whatever they agree to void when they invade again. Russia is really good at changing the definitions of things when it suits them.

JohnDClay ,

Why would they lose more than they’ve already lost? Their expectation is that western aid will continue, allowing them an advantage over Russia in the long term. Russia thinks Western aid will dry up (maybe due to trump being elected) so their anticipated outcome is better in the long run. When the question of enduring western aid is answered, there will be less of a difference in expectations, meaning continued conflict isn’t advantages since it’d cost more than both sides gains expectations.

I highly recommend looking into the game theory behind the war. youtube.com/

JohnDClay ,

Russia can claim anything is a political reason. Russia and a lot of western nations have more Nazis than Ukraine, but Russia still used that as a justification.

JohnDClay ,

Plus they’re asking for more money that they haven’t stolen yet. Russia doesn’t even control large parts of the territory it’s decided to annex.

JohnDClay ,

At least on their home turf with their western equipment, yes. Russia is throwing pretty much everything at Ukraine, and Ukraine is doing pretty well.

JohnDClay ,

You think Russia will be able to take kiev now? Now that their military is badly mauled, they don’t have the element of surprise, and Ukraine has much more equipment and training than when the war began?

JohnDClay ,

So stupid to support a dictator

JohnDClay ,

It makes no sense as a diversion. Way too much effort for that. They thought they’d face little resistance, similar to Crimea.

Here’s a game theory analysis on the causes of the war. youtu.be/pBwT-5z9R5A

Of course Russia’s aims were to get Ukraine to accept their terms in Istanbul, namely that they get to keep what they’ve stolen. Fundamentally the same offer in the headline here.

JohnDClay ,

Putin that applies to, not Zelenskyy.

JohnDClay ,

I agree subject matter experts are important. That’s why I linked to a professor on international relations and war who wrote a book on the subject.

JohnDClay ,

Hmmm? Do you know what game theory is? It explicitly deals with incentive structures and is how academics decode nations motives.

JohnDClay ,

Putin jailed opposition parties and critical journalists. He holds elections, but doesn’t give the actual numbers, meaning they’re just polls.

JohnDClay ,

It includes both perceived military capacity and geopolitical strategy. Game theory helps with the latter.

Here’s more info on theories of Russian victory from a military analyst specializing in Russian military and a defense economist. That should help with the capacity side of the argument.

JohnDClay ,

Could you give examples? I’ve found Peruns analysis to be spot on in hindsight.

Or were you taking about Nelson?
