  • Plenty of countries have national parks btw. Many of them had them before America.

    Well not really though ? Yellowstone established in 1872 is generally considered the first national park, in the modern sense of the term*, and inspired others to follow in the next couple of decades in Canada, New Zealand and Australia. It wasn’t until the 1900s that the first national park was established in Europe.

    * there are a couple of other places that also claim this distinction, depending on how exactly you define what a national park is, but not many

    Calling national parks “America’s best idea” is a quote from historian and environmentalist Wallace Stegner - I think the point of it is not to toot some US exceptionalism horn - in context it’s more of an acknowledgment that America deserves a lot of criticism - saying that national parks are America’s best idea is actually putting a bit of shade on other American exceptionalism claims, especially during the Reagan “shining city upon a hill” era.



  • This is true, however you can still be targeted for extra checks by both customs and immigration if they have a reason to suspect you, even when departing the US. Both CBP and ICE have access to departing passenger lists.

    For example you are required to declare larger sums of cash being carried out of the country (over $10k). You are supposed to go to customs and fill out a form, but many people do not know this, often legal immigrant workers taking cash back to their home countries. CBP uses dogs trained to smell cash and patrols departure lounges in airports, and if they pick you out, you can be searched, and any undeclared cash will simply be seized if found.

    It’s easy to imagine with the current administration they could start targeting people based on social media posts or some kind of previously compiled political profile or “enemies” list or whatever, if they aren’t already.


  • photography might be an area where digital hasn’t caught up, since film’s resolution is down to the molecular level

    Film resolution is limited by the size of the silver halide crystals that make up the light sensitive layer of the film. Crystals can come in different sizes, but their sensitivity to light depends on their size - generally you need pretty large crystals for usable photographic film, somewhere between 0.1 and 10 microns (depending on the film ISO rating) - about 3-5 orders of magnitude larger than what you would consider molecular scale.

    When the film is developed the crystals are visible as film grain limiting the resolution in some ways similar to pixel size of a digital camera (although there are differences, since the crystal size is not completely uniform but rather has a specific distribution, creating a more random effect than the regular pixel grid of digital cameras)

    The pixel sizes on modern high resolution digital camera sensors are actually similar, down to 0.5 micron. It’s hard to make an exact comparison, but I have seen estimates that you need a full frame digital sensor of somewhere between 10 to 50 megapixels to equal the resolution of 35mm ISO 100 film.

    And modern sensors are much more light sensitive than film, which allows you to shoot more optimally and give you more flexibility (less exposure time, potentially higher f-stop with better lens resolution, lower ISO, less light, etc.) and therefore achieve potentially better results in more conditions. Add to that the hassle and costs of working with film, and most professional photo work is now done in digital as well. Film is generally only used for stylistic purposes, by purists who are not satisfied with digital simulation.



  • I do understand the sentiment. I am a bit old and have seen words and phrases shift meanings in my lifetime and feel occasional irritation due to it (although I try to care less and less about it :)

    I do find it harder to get worked up about a word that acquired additional meanings in the 14th century though - that ship has truly sailed :) Like who am I to school Mark Twain on the meaning of words.

    I also find the ability of English to use the same word with different meanings and the power of context quite interesting (the fact that individual words exist in English with 100s of distinct meanings is really quite mind blowing.)

    Ideas and concepts can sometimes be fuzzy as well with large overlaps, and insisting on too much specificity, precision and delineation in the language can be counterproductive to effective communication just as much as allowing too much flexibility can - but yeah, I guess there will always be some tension there and differences of opinion.

    Language is often messy, but always fascinating. (And btw, I never said good or bad or right or wrong - I don’t feel it’s really my place to place such judgements)




  • I am not sure you were as wrong as you think - see definitions 2 and 3 here

    Usage of words shifts and sometimes expands over time.

    More references here or here

    I would personally definitely interpret “apparently” and “plainly” differently - “apparently” to me is “the evidence so far does seem to point this way, but I am not necessarily convinced, or have strong feelings either way” vs “plainly” is “the evidence is clear, I am convinced, and so should you be” - although obviously context would matter as well and could alter this interpretation.

    Edit: even your example usage “I’ve been trying to get myself out of that habit, but even judging from my comment history, it’s apparently pretty hard” - to me the usage of “apparently” here indicates similar tension and/or contradiction, in this case between belief/intent (I am trying to stop the habit) and evidence (but my comment history shows otherwise) - it wouldn’t work quite as well with “plainly”

    It would work with “evidently” but carry more of a connotation of confirmation and shift the emphasis (I am trying to, but it’s hard as confirmed by evidence) rather than contradiction (I would like to think I am doing it, but evidence shows otherwise) - of course you might have meant it either way (or even neither) - I am just saying how it reads to me.

    But your citation gives both statements:

    “In fact, the monkey would almost surely type every possible finite text an infinite number of times.”

    and

    “The theorem can be generalized to state that any sequence of events that has a non-zero probability of happening will almost certainly occur an infinite number of times, given an infinite amount of time or a universe that is infinite in size.”

    So when you say the number of times is “unknowable” the actual answer is “almost surely an infinite number of times” no ? Since the probability of that can be calculated as 100%. The mindfuck part is that it is still possible that no monkey at all will type a particular text, even though the probability of that is 0.

    The probability that only 2 monkeys will type the text is also still 0, same as 3 monkeys, 4 monkeys, etc. - in fact the probability of any specific finite number of monkeys only typing out the text is still 0 - only the probability of an infinite number of monkeys typing it out is 100% (the probabilities of all possible outcomes, even when infinite, have to sum up to 1 after all)

    We just know that it will almost surely happen, but that doesn’t mean it will happen an infinite amount of occurrences.

    Basically, if we know “it will almost surely happen” then we also know just as surely (p=1) that it will also happen an infinite number of times (but it might also never happen, although with p=0)


  • Ok, this is interesting, so thanks for pointing me to it. I think it’s still safe to say “almost surely an infinite number of monkeys” as opposed to “almost surely at least one”, since the probability of both cases is still 100% (can their probability even be quantitatively compared ? is one 100% more likely than another 100% in this case ?)

    The idea that something with probability of 0 can happen in an infinite set is still a bit of a mindfuck - although I understand why this is necessary (e.g. picking a random marble from an infinite set of marbles where 1 is blue and all others red for example - the probability of picking the blue marble is 0, but it is obviously still possible)

    That’s the thing though, infinity isn’t “large” - that is the wrong way to think about it, large implies a size or bounds - infinity is boundless. An infinity can contain an infinite number of other infinities within itself.

    Mathematically, if the monkeys are generating truly random sequences of letters, then an infinite number (and not just “at least one”) of them will by definition immediately start typing out Hamlet, and the probability of that is 100% (not “almost surely” edit: I was wrong on this part, 100% here does actually mean “almost surely”, see below). At the same time, every possible finite combination of letters will begin to be typed out as well, including every possible work of literature ever written, past, present or future, and each of those will begin to be typed out each by an infinite number of other monkeys, with 100% probability.






  • Once you finish it, it’s actually really fun watching other people’s playthroughs as well - getting to relive some of the moments vicariously through other people’s eyes is almost as much fun as experiencing them yourself the first time.

    It’s also quite amazing just how different each playthrough can be, since the game is so non-linear, people take some crazy paths to get to the end ! It can be frustrating as well when someone just can’t see what is in front of their face though :)

    There are also so many subtle elements scattered around that most people miss on their first playthrough, and watching someone else play it really made me appreciate many of the details I missed on my own playthrough and even make connections I didn’t before, and understand aspects of the story that I didn’t fully get the first time.
