  • These warnings DO serve a purpose, even when they are legally void. People tend to follow less closely behind trucks, secure their belongings when parking, and take other actions to avoid the clearly indicated potential loss.

    If a load breaks and cracks your windshield the truck is likely liable, but depending on how close you were following you may share some liability as well – especially if you, say, collide with the truck or another car after your windshield breaks. The law may hold that the sign has no effect, but itll be hard to convince a jury that you didnt know the truck was a potential hazard after you say that you saw it.




  • Terrorism is a problematic word. Some adults use it to mean “violence I dont like”, but that’s just a kind of lying.

    I dont like discarding words, however, so here are two workable definitions for you:

    1. An act of war against a civilian target without a formal government direction.

    (Broadly covers most mainstream reporting and legal criminal enhancements)

    1. Any violent act against a stranger intended to change the political opinion of the attacked.

    (Very specifically targets the action without regard for the actor.)


    Also, while this may be obbious, my dislike for any definition of terrorism as just “bad violence” means I need to acknowledge that sometimes terrorism is a morally right action. Guy Fawkes, John Brown, and intentional riots would be plausible examples of the same.



  • The whole universe? Absolutely. Even the smallwst infinity is larger than any countable sum.

    The visible universe, meaning those close enough that a photon could have passed from there to here since the “big bang” faded enough to allow such transmissal? I don’t know offhand.

    A simple web search suggest that our galaxy has less than 1011 stars – 400,000,000,000 or so. ( https://en.wikipedia.org/wiki/Milky_Way )

    Finding our other figure is a bit harder, since trusty Wikipedia doesn’t include a direct figure and the first few articles I could find was from the BBC and used number names instead of scientific notation, which is ambiguous at this scale. ( in the long scale we only have milliardaires, and Elon Musk’s brief paper fortune was a billion rather than trillion.)

    Thankfully a NASA articke linked to what appears to be the underlying research paper, and gives us a helpful number of 2x1012. (2,000,000,000,000)

    https://assets.science.nasa.gov/content/dam/science/missions/hubble/releases/2016/10/STScI-01EVSR313NHNAC17DF62MP9QV9.pdf

    So, if the paper is right then, yes, there are more galaxies in the observable universe than stars in the Milky Way. But, the paper was an indirect measurement that increased the galaxy count by a whole order of magnitude, so there may be only 2x1011 galaxies. Except, of course, that the estimate of stars in the miky way was an estimate and could be as little as 1/4 of the number I cited above…

    And if the paper is wrong and the truth of the estimate is in the middle, both of our numbers could be 2x1011, with approximately one star in our galaxy for every galaxy in the observable universe.



  • Living in Europe in a country where you are more or less protected against layouts, were unions are allowed to exist. Jet it is so difficult to get the people to get their head out of their butts to do some solidarity or even improve their own conditions.

    It sounds like you’re in an anti-Union country that is only pretending to care about worker’s rights.

    Here in the horrible individualistic pro-capitalism USA workers are struggling to get their unions recognized, largely because once a union is organized there is a whole industry of advocates and lawyers who will push for the bargains to be made, for those bargains to be (at least slightly) better than the law, and for the rights in law or bargain to be protected viciously. And even if you’re not in a union, there are sharp public and private mechanisms to respect labor rights.

    Not all of the USA is anti-union, and the parts that arent can and do strike when they don’t get an honest and fair deal.







  • It’s a grammatical one, not a philosophical one. And, now that I think of it, it’s also one with a definite answer.

    If you waved a magic wand and had a chicken come out of a leathery egg lay by a lizard, a watery egg lay by a fish, or the sort of large egg an oatrich usually comes from, we wouldn’t call any of those a “chicken egg”

    And, conversely, if by super-advanced genetic engineering we made chickens who lay eggs with bacon or cheese or just all whites, we’d call those eggs “chicken eggs” when we talk about the shells themselves and not the contents therein.

    So the chicken came first. And the first chickens hatched from the eggs of some other bird.


  • You’re thinking about lagrange points – the places in a (dissimilar?) two-body system where the gravitational pull (and kinetic energy?) from both is equal and thus relatively stable.

    Not a physicist, obviously.

    Also, be aware that the effect of gravity diminishes with distance. We’re pulled towards the earth at about 9.8m/s/s here on the surface, but as you get further away that 9.8 drops off on an exponential curve.


    This gives me a chance to repeat the best argument for why Star Wars is higher tech than Star Trek. When the enterprise gets to a planet they orbit, and the artificial gravity is only an internal issue. In star wars we see gravity shift as ships list due to damage or even fall towards planets, because they aren’t orbiting; they’re just hovering above the planet, presumably with their artificial gravity just working enough to stop the ship itself from falling.






  • From the outside, it looks like there are at least three levels of actor.

    1. Everyone starts as a “nobody” – no credits, no SAG card, and no agent. Most films hire a bunch of these folk to act as living backgrounds or “extras”, but now and again they’ll give a nobody a role and they’ll move on to the next step.
    2. “Credited actors” are those who have credits and agents and whatnot, but still need to audition and may very well work a separate job for when they don’t get cast enough to pay the bills.
    3. Very successful actors eventually reach a point where they stop auditioning, and are instead reached out to directly with script ideas and roles essentially written with them in mind.

    The distinctions between the second and third groups are very soft and will change with the speed of fashion and rumor, while the gap between the first and the other two is so dramatic that I’m sure someone out there doesn’t even consider extras to be actors.
