  • USA not liking a Russian-aligned island neighbor is similar to China not liking a USA-aligned Taiwan providing a military launchpad on their maritime border.

    It will be interesting to see which strategy turns out to be more effective: China's carrot and stick approach to reclaiming Taiwan, or USA's belligerent vendetta against Cuba.

  • Large physics models are increasingly used to bypass simulation

    Jump

  • I don't know if this is the full explanation, but the article does touch on how the LPM can be tweaked to match physical tests:

    The trick is to incorporate experimental measurements to fine-tune the model. If a physics simulation doesn’t agree exactly with experimental data, it is often difficult to figure out why and tweak the model until they agree. With AI, incorporating a few experimental examples into the training process is a lot more straightforward, and it’s not necessary to understand where exactly the model went wrong.

  • @ casualconversation l've always known that time is an artificial construct ever since I was told to sit down to study

    Jump

  • kinda seems like time is an emergent property being caused by the illusion of distance, which is itself an emergent property of a holographic projection of lower dimensional base physical reality onto a higher dimensional space - as if we're living in a multi-dimensional hologram being projected from a singularity

    why does light not experience time? from the photon's perspective, its created, travels any arbitrary 'distance' and is absorbed at its destination, all in the same instant . . . as if it didn't actually go anywhere at all in the base layer of physical reality

  • Do you think we will have carbon-free sea travel?

    Jump

  • Electricity produced at offshore wind farms is being used to turn water + atmosphere into ammonia (NH3). There are already a few cargo ships in operation that use ammonia as fuel instead of oil, and many more in production.

    Using ammonia to store energy instead of lithium batteries gives about 10x the energy density per kilogram, and 3x energy density per liter.

    Iraq mourns its dead after worst strike against its army since the start of the war: ‘Why did the Americans attack us?’

  • Should Democrats raise the immigration quota to 1m per year?

    Jump

  • First of all, fuck capitalism. Its the origin of this problem.

    Second of all, until we can abolish capitalism, it will remain the case that labor is treated a commodity and wages are therefore subject to supply and demand.

    Third, most jobs in USA pay sub-poverty wages. Its wage slavery. Salaries need to increase.

    Therefore, policymakers looking out for the economic interests of the working class should do everything they can to create labor scarcity, including shutting down all immigration (decrease supply), abolition of taxation on small businesses (increase demand), and direct government subsidies for nationalized large businesses to achieve economies of scale in strategic sectors (increase demand).

    Turns Out That Advertisers Not Wanting To Fund Neo-Nazi-Adjacent Content Isn’t An Antitrust Violation

  • What is the limiting constraint on space based kinetic weapons in the present and future?

    Jump

  • Rods from God deliver the energy of about 12 tons of TNT.

    For comparison:

    The British used 12 ton "Tallboy" bombs, carried by Lancaster bombers, in WWII against submarine pens.

    The "Little Boy" nuke delivered the energy of 15,000 tons of TNT.

    Some modern ICBMs carry 10 warheads, each of which delivers the energy of 475,000 tons of TNT.

    One benefit of dropping a tungsten telephone pole from orbit is that there's no good way to stop it, because its just a chunk of metal moving very fast. Hitting it with a missile might scratch the paint, but won't significantly alter its course.

    The main drawback is the expense of getting them into orbit. Falcon 9 can lift 2 of them if the poles are cut in half to fit under the fairing, at a cost of about $70 million. That does not include rocket engines, fuel, and targeting computers needed to get those 2 tungsten rods out of space and onto target.

  • NASA kills lunar space station to focus on ambitious Moon base

    Jump

  • Its about time! There's nothing a permanent space station orbiting the moon can do, that a fleet of rotating Starship-class vehicles can't do better.

    Forcing lunar landers to rendezvous with the station before attempting a landing just wastes fuel.

    Forcing a cargo ship to rendezvous with the station also wastes fuel - if a lander needs to top off its tanks before attempting a landing, why not dock it directly to the cargo ship? And then return that cargo ship to Earth to be refilled and reused again and again as a temporary supply depot.

    Hopefully they'll fully cancel the Senate Lunch System program soon too!
