  • I also get annoyed at lightning fast responses. And I agree 100%

    It takes no time or energy to come up with one answer to a question. I’m fact, I think most humans’ brains are built for snap decisions like that.

    But to weigh multiple answers against each other, poking holes in the answers you are most inclined to believe? That takes thought. And if someone is not doing that for you, then odds are, their brain is simply letting them take the discussion less seriously than your brain (or your morality) allows.

    So I think you have every right to feel frustrated at such behavior.

    A lot of people are offering explanations, but I think I’m going to give one too.

    Think of recoil in a gun. If you don’t have a mental image of it, watch a few youtube videos of people firing handguns. Look for videos of big, high-recoil handguns, like the Desert Eagle or the Magnum (or the Super Ruger Redhawk according to chat-GPT).

    You need to get a good look at handguns pushed backwards as they are fired.

    Now think about this: those bullets aren’t pushing against an atmosphere. They are pushing only against the inside of a gun.

    But when this tiny, tiny bullet pushes super-fast against the gun, using the gun to accelerate to incredibly high speeds very quickly… it pushes the gun really hard in the other direction.

    Get that mental image into your head. Small object can push large object with a lot of force by kicking off of large object with insane speed.

    Now: Take away the person holding the gun. Take away the planet. Take away the atmosphere. Put that gun in space and pull the trigger again. (Just make sure to use a gun that has modern ammunition that doesn’t require oxygen to fire).

    What happens to all that recoil? What does the recoil do to the gun now? The bullet still goes flying out of the chamber. Still does this by pushing against the gun.

    Hopefully it should now be easy to imagine that the gun will start moving.

    Rocket fuel is basically a tank full of bullets.

    The main function of rocket fuel is “heavy stuff that is shoved out of the spaceship to make it move.”

    The reason we use highly explosive fuel is because “shoving heavy stuff away from you at the speed of a bullet” is going to move you more than “shoving heavy stuff away from you at normal speed.”

    Does this make any sense?


  • I think the idea that billionaires are created by any kind of motive is the wrong lens.

    Their wealth doubles faster if they lack egalitarian values. So the millionaires who end up becoming billionaires are the ones who lack egalitarian values.

    The values they do hold could be anything from, “everyone wants to win; I’m just winning harder” to “God told me to” and it won’t matter as long as they keep reinvesting and growing their wealth faster than the economy or ecosystem can sustain.

    What we’re witnessing right now is not a set of ideas or beliefs, but an exponential growth equation – with all of the overwhelming speed and transformative power such an equation carries.

    Exponential growth is the reason for everything from the mammoths’ extinction to rotten food and the lethality of cancer. It transforms entire systems, outgrowing (and often destroying) its own host.

    If your society has currency but lacks any chemotherapy / surgery to remove concentrations of the aforementioned currency that start growing at a cancerous rate…

    Then it won’t matter what values are common or uncommon: your society is eventually doomed.

    It could take a hundred years or a thousand, but eventually, a pile of wealth will emerge that multiplies until it consumes everything.





  • Oh yeah, they normalize IQ every year, and 100 is always used as the median.

    But thanks to the Flynn Effect, getting a 100 (the number they always choose for the middle) in 2024 means you’re significantly smarter than someone who got a 100 in 1990.

    So when Carlin said, “think of a person with average intelligence” he was calling to mind (to his 1990 audience) a person who was average in 1990 but would score [EDIT: I originally said 70s to 80s, but I was off by a lot. Such a person would actually score right around 90 points] today.

    This is what happens when you take the lead out of gasoline.








  • Oddly enough, on a computer, I have not seen secant, cosecant, or cotangent.

    I have seen sin, cos, tan, arcsin, arccos, and arctan.

    Though the arc functions will only have one parameter, so if this is homework, you’ll probably be avoiding the arcs and using secant and friends

    Anyways:

    sin ( angle )

    Term In this example
    Parameter Angle is the parameter. It’s in radians, so in Java you’ll use a conversion like Math.toRadians(a) on whatever number you’re going to use as an argument
    Argument If I were to call sin(Math.PI / 4) then I would be passing the argument π / 4 to the function.
    In other words, if a parameter is a question, then an argument is an answer. If a parameter is a coin slot, than an argument is the coin you choose to insert.
    Operation An operation is practically synonymous with “function”. It is performed on inputs to arrive at an output. However, usually in code, I hear “operation” used to describe things like /, *, and +. Things that have multiple inputs and a single output, all of the same form.

    If someone is asking you, "which operation should you use in the body of function sin ( hyponetuse, opposite ) then I imagine the expected answer would be, / because

    1. / is an operation, and because
    2. opposite / hypotenuse will perform the division that yields the sine of whatever triangle those two sides belong to.

  • An algorithm is the meat of a function. It’s the “how.”

    And if you’re using someone else’s function, you won’t touch the “how” because you’ll be interacting with the “what.” (You use a function for what it does.)

    You will be creating your own algorithm by writing code, however. Because an algorithm is just a sequence of steps that, taken together, constitute an attempt at achieving an objective.

    Haus is saying all the little steps that go into approximating sine occur directly on the hardware.
