    If you assume that a “bullet” is a unit of momentum (the mass and velocity of a bullet) and “square child” is actually just referring to the mass of a child who happens to be square shaped and not the mass of a child squared, then “bullets per square child” is describing valid units for a velocity

    The state (as defined by Engles, Marx, Lenin, etc.) is the problem. Like this is exactly what it does by definition.

    If the government forms an alliance with the market it becomes a slave to the market.

    There are more homes than homeless, more food than starving kids. Life saving medicines can be extremely cheap to produce but are sold for fortunes. Everywhere you look, the bourgeoisie are literally holding people’s lives for ransom… and the government does nothing.

    In fact the government does less than nothing. It is the government that facilitates the hoarding of these resources. It is the government that enforces patent laws that allow life saving medicines to be kept from those in need. It is the government that enables and legalizes this racketeering by the rich.

    When you live in a society where politicians talk equally (or more) about how they’ll help the market as they talk about how they’ll help their citizens—which is what their job is supposed to be—are you really surprised?

    Are you really surprised that a government which chooses to let its people go unhoused just to keep the real estate market up is a government in which wealth holds the power? Are you surprised that a government that shuts down worker strikes and forces compromise on the side of the exploited rather than solely on the side of exploitative corporations is a government that can be manipulated by the owner of multiple massive companies?

    There is nothing surprising here. The system is working exactly as it is intended to. The problem is not a few members of the bourgeoisie colluding to manipulate the state because that’s how the state always works. The problem is the state.

    If you would like to learn more about “the state” I suggest you read State and Revolution. That’s what made me switch from “oh we just need to tax the rich” to “the rich should not exist.” It also is just kind of impressive how Lenin describes many things that are very relevant today despite the fact he wrote this short book over a century ago.

    Well actually it’s the other way around. The reason imaginary numbers were invented was to solve a problem we’d been crying over for centuries.

    Then, as in most cases, solving one problem opens the door to millions of other problems like why in the fuck does the universe use these imaginary numbers we made up to solve cube roots?

    Why is i a core part of the unit circle with like ei*pi ? “Oh that’s because i is just perpendicular to the real number line” ?! Say that sentence again, how the fuck did we go from throwing sharp sticks to utterly deranged sentences like that? More importantly why do utterly deranged sentences like that accurately describe our universe and what is the next ludicrous math concept we’re going to discover is integral to the function of the universe?




  • Wait. I just realized energy also creates a gravitational pull, and the death star’s whole thing is destroying a planet right? That’s got to take a huuuge amount of energy because the explosion has to massively overcome the gravity holding the target together.

    A quick google search says you’d need 10^32 Joules to blow up the earth. E=mc2 so dividing that energy by the speed of light squared gives about 1.1e15 kg of equivalent mass which is relatively small compared to earths mass (6e24) but still large.

    For reference, if the radius of the Death Star was 1000m you’d get about 5.2m/s2 acceleration from just that energy in its core.

    But if the Death Star is able to blow up multiple planets, then the energy it has to have on hand goes up. So if the Death Star contains enough energy to blow up 5.4 billion planets, then just that stored energy would have nearly equivalent “mass” to the earth.

    But gravitational acceleration is inversely proportional to distance squared. So since the Death Star is small, you wouldn’t need that much energy to get earth gravity. If we assume the Death Star has about a 160km radius, then you’d only need enough stored energy to blow up ~45,000 earths to get a surface gravity of 9.1m/s2.

    This gravity would increase as you got closer to the core or whatever part stores all that energy. But if you spread that energy out a bit you could probably extend how large the earth-like gravity range in the station would be.

    The mass of the structure itself would contribute to the gravity too so that 45,000 is probably an overestimate.

    TL;DR: From rough math in my head, assuming a radius of 160km, point mass, and ignoring the mass of the structure, you’d only need to store ~5e19 J of energy in the Death Star to get earth like gravity on the surface. That is approximately the amount of energy required to blow up 45,000 earths


  • Dark Souls remastered. Getting cursed just before reaching a boss and having no money to buy a cure forced me to either give up, grind, or “get gud.”

    I beat the boss without getting hit once. I know other people probably do that for every boss but for me that’s a big achievement since I suck at combat and video games in general.

    In other news, the game is hard but beautiful and the level design is pretty impressive. I’m looking forward to marathoning the other souls games after this.
