  • Fun fact: pushing things into the sun is really difficult. Short version: imagine spinning a pendulum, then trying to slow it down, except the pendulum is 100kg (200lbs) and moving at 87 Mach.


    Long version:

    Anything launching from earth will have a significant orbital velocity around the sun by virtue of starting at the earth’s own velocity (~30km/s, about 67000 mph). That velocity makes it hard to actually reach the sun.

    Consider that even the sun’s gravity isn’t enough to pull in the earth at that speed. Simply applying thrust towards the sun would have to amount to a significant portion of the sun’s gravity to make a noticeable difference.

    So to reach the sun, you’d ideally have to get rid of that excess orbital velocity instead. That requires a lot of force, to put it mildly. That kind of force requires powerful boosters and a lot of fuel. Of course, getting those engines and that fuel up there also takes powerful engines and a lot of fuel. But the larger the rocket, the heavier it’ll be, so it’ll require even more fuel…

    There’s a phenomenon dubbed the “Tyranny of the Rocket Equation”. It describes the problem that, at some point, the extra weight required to make a rocket more powerful is greater than the extra power it provides. That basically puts a limit on how strong a given engine can get. There’s a lot of work being done on getting them to be more efficient, so that limit is getting higher, but the bottom line is:

    It would require an immense amount of resources to slow an object enough to toss it into the sun, and more resources to get them to that object in the first place.

    Physics is a cruel mistress and a mean spoilsport.



  • Me when I get a request for PII pertaining to a suspected corruption case: Have one of our corporate lawyers give me a written and explicit statement of what data I’m supposed to send to whom or get bent. I’m not touching that with a ten foot pole and gloves unless I have a legally solid affirmation that what I’m doing won’t come back to bite me, and that our workers’ council knows about it and will back me up.

    I’m reluctant to even confirm that I can get that information in the first place. I mean, I’m the one with full access to the audit tool, so I probably do, but I’d have to access that data in the first place to check. I don’t think that anyone would notice or care so long as I don’t share that information, but as you said: dangerously radioactive; don’t touch if I can help it.





  • Eurydike I was a boss bitch. Not only was she unusually prominent in politics for a queen, she also engaged in foreign policy on her own, successfully negotiationg with a foreign general to have him protect her late husband’s throne against a pretender, apparently without any participation from her son-in-law, who served as regent at the time.

    The youngest of her sons, Phillip II, would go on to reform the military and secure hegemony over Greece, laying the groundwork for the invasion of Persia that he never got to carry out. After his assassination, that invasion was instead performed by his son, Alexander III, later dubbed “The Great” for this feat.

    It should be noted that, with Alexander being on campaign for basically all of his reign and generally not too interested in domestic rulership, his mother Olympias of Epirus was the de facto ruler of Macedonia. Behind the successful general are two powerful women that first protected his father’s throne, then took care of the actual ruling so that he would be free to hunt glory.
