what neutrons? we're talking about shielding of spacecraft moving out of earth's magnetosphere, not a spacecraft travelling through core of active nuclear reactor
the kind of radiation that is relevant are high energy protons (and alphas and electrons, with a sprinkle of heavier nuclei) from sun, mostly. there's no relevant source of neutrons
(and incidentally water is pretty good at absorbing neutrons too)
water does not expand upon irradiation, what the fuck are you talking about. you can't reflect high energy protons (what would be important in radiation in interplanetary travel) you can only either absorb them or let them pass, there's no third option, same for anything above uv and electrons
to a first approximation (rather good one at that) (for gammas) absorption is proportional to how much mass per area unit is used as a barrier. 1 g/cm^2 of water is just as good barrier as 1 g/cm^2 of lead or steel. this means that you can absolutely use completely normal, regular potable water as a radiation shield
Water in its purest form would have to take on mass to “absorb” radiation, expanding a hull and destroying it over time.
i'm not even sure what it's supposed to mean, unless your understanding of ionizing radiation is uncut nonsense
chemically speaking, it's completely fine to irradiate water because whatever is formed as a result of radiolysis would just most of the time form water back, with the rest becoming very weak solution of hydrogen peroxide. this is big part of the reason why water is used as a coolant in nuclear reactors
there are also specific nuances to stopping anything that is not gammas, like secondary x-rays, gammas from neutron absorption etc and this actually favours light element shields, like water or liquid hydrogen, for this kind of radiation shielding
i don't get what you fail to understand, water doesn't became radioactive or harmful in any other way after irradiation, and irradiation of food is routinely used for extending its shelf life
"remove" what exactly? water is not alive so it's okay to irradiate it https://en.wikipedia.org/wiki/Food_irradiation
thank brexiters for that, it's illegal in eu
nvidia executive called saltman a podcasting bro
the problem with that is that training can't be done "immediately" it takes tons of compute
Copyright and IP concerns disappear with an open dataset.
i don't think i'd agree with that, doesn't matter if dataset goes open if content went there without consideration for authors
also even things like thispersondoesnotexist were used to mass-create fake identities and such
i'm not. just because he's an underdog here means that you're gonna ignore all the harms of generative ai up to this day? it's like complaining that big oil stole the idea of adding tetraethyllead to gasoline from you and you got no profits from that as a result
You might be semi-comfortably running linux mint cinnamon on these (assuming 4gb ram) with xfce you're trading clunkiness and ancient looks for lower memory usage
no idea about the usual suspects, wifi, bt, graphics probably will require tinkering as is tradition
Electoral college is fucking weird
That you disallow prisoners to vote, but a felon can run as a candidate
That you end up in situation where there are hours long lines and you don't have one station per, say, 1000 people at most
Registering to vote is weird, but that is i understand mostly a consequence of not having countrywide ID standard. In my country you're automatically registered where you live, and IDs are free of charge and mandatory to have (not driving license or passport. there are fees for these)
Election isn't on weekend, there's zero reason why it couldn't be or it could be made national holiday. There was even free public transit for election day in my city, but that one was paid by the city
That some of people (republicans) seem to be into politics in the same way ultras seem to be into football, it's still fucked up but i've seen it in other places so it's not that weird by now
