  • You now need to remember his velocity, his position on the map, the direction of his flight, his altitude, his plane’s weight and who knows what else, I’m not a pilot.

    You’re not wrong per se, but I’m having trouble fathoming gigabytes of data being consumed by these types of parameters. You could probably track hundreds of thousands of airplanes with that much space. The only thing that I could imagine taking up that much memory is extremely detailed airflow simulation.

    However, as a rule of thumb, the vast majority of memory data for video games is in most cases textures and geometry, and not so much the simulation. Based on the article, it seems this game streams high resolution geometry data based on your current location on earth, which I would say is the most probable reason it asks for so much memory.




  • Also, sour patch kids have a weird ingredient in the coating that most electrolyte stuff doesn’t have. Potassiumsomething something, irrc?

    Probably you’re referring to tartaric acid, potassium bitartrate. It’s added to candy to stabilize invert sugars, keeping them from crystallizing. You can buy it in powder form, usually called cream of tartar.

    I don’t know what it does for hydration, but I suppose it would help top up potassium levels.

    So, yeah, bottom line: you only need a delta-V of about 12 km/s to get out of the solar system, but a delta-V of 30 km/s to get to the sun without going into orbit.

    This is true, but the possibility of gravity assists mostly nullifies the difference. If you can get out to Jupiter you can basically choose: either let it sling you out of the system, or let it cancel out all your orbital velocity so you fall into the sun.

    These are all technically correct but fairly inconsequential. Even just to graze the sun you need to lose 90% of your orbital velocity. And although everything orbiting the sun will eventually fall in, the friction is really low. It will take billions of years to lose enough velocity to fall in.
