    When I said "ray" I just meant an imaginary line that could be drawn to extend in a given direction, not a literal particle escaping. It was mostly to think of a way you might conceptualize an orientation of an object that may not have any dimension. As in, if the matter just outside a singularity rotates, perhaps you could consider it to rotate? But I'm not sure that would be accurate to say anyway. My grasp of the physics of black holes is obviously pretty loose. :)

    Thanks for taking the time to explain!

    Technically couldn't a ray emanating from a singularity rotate? Like, the point could have a sort of orientation without having any real measure?

    Not saying that's the case here, but I think it could happen.

    Edit: I may be a little confused about what you mean when you say narrower aperture. When you focus stack, you will be using a relatively wide(r) aperture, if you are not, you will need a somewhat narrow(er) aperture to get sharper focus.

    Focus stacking is usually done in post. The option in your camera will most likely just take a series of photos with the focal point changing slightly every time, and you can stitch those together later. Photoshop will do it automatically, or you can do it yourself with masking on different layers.

    There are some cameras that will do the stitching for you. I know the OM-1 (the camera I generally use) does this, and probably other models. I tend not to use it though since it saves the end result as a jpg and I prefer to process my own images from RAW.

    I am in the same boat, not a pro, so my explanation may not be the best:

    It's more to do with the fact that when you are taking macro shots you are generally very close to your subject, and unless it is a very thin object on a single plane parallel to your lens, you often really have to stop down to get the entire subject in focus (like f/8 - f/11). If you are shooting at f/2.8 you might only get a single petal on your flower in focus.

    So if you see a shot of a small object with some depth to it, which is entirely in sharp focus, but then you have a super creamy bokeh on objects that are only a couple inches further away, there is a good chance that it was achieved using a wider aperture and stacking the in-focus bits of several shots. That's what I look for, anyway.

    Hope that helps. B&H has good articles on DOF in macro photography and focus stacking that explain it better than I can!

    When you have a really shallow depth of field on a macro shot, yet your entire foreground subject is tack sharp, it is often achieved by focus stacking. Otherwise, it can be quite difficult to blow out the background while having your entire subject in focus (even though it is quite small). I have done it with flowers before, so I think I am just used to the look. It has a sort of isolated, dreamy quality.

    If you're looking for a relaxing tea, I highly recommend lavender. I use a tea ball filled with dried flowers that I bought in bulk online. Honey optional. Chamomile is nice, but it has never done much for me beyond "a cup of something warm is relaxing".

    I did find that the fake article titles were often too "on the nose" to be believable, so I guess that's one level of filtering. But you are right, if you can't explore the article and its sources, you are just guessing whether it is true based on whether it sounds or feels true.

    I have another issue with the fact that a headline can be a "real" news headline, from a source that may have a veneer of reputability, but could still very much be full of bias. Is it "fake news" if the article exists and technically contains some verifiable facts, but is otherwise full of propaganda? It gets blurry.

    I have a lot of dream related phenomena that I experience regularly (sleep paralysis, out of body experiences, etc.) but I generally chalk that up to the fact that I probably have some kind of sleep disorder.

    But there was one dream I had that I cannot easily dismiss. A few years ago, my grandfather was living alone and declining in health. He and I were extremely close when I was growing up. We (my mom particularly) would go check up on him during the week, and he had home health aids that checked in as well.

    One night, I had an unusually vivid dream where I saw him - in blue robes, in a heaven-like setting, happy and healthy and strong. When I woke up, I made sure to journal the dream, as I keep track of significant dreams. Just a few minutes after I finished writing, my mom calls me and tells me that my grandfather's health aid had showed up and found him lying on the floor; they had thought he had a fall during the night. They sent him to the hospital, but he wasn't really coherent and was pretty obviously reaching the end.

    I visited him as soon as I could and said my goodbyes, and he died the next day. I felt like the dream gave me some sort of closure, like his spirit reached out to me and let me know that he was ready to move on?

    I actually had a few dreams after that where he visited me, but we both knew he had died and couldn't stay. I at least got to share the news with him that I was expecting a child (I found out I was pregnant about 4 months after he died). I have not seen him in a dream since.

    Perhaps it was a hypnopompic hallucination? I ask because I have many experiences waking up from nightmares and hearing bizarre sounds or seeing bizarre things. Like ice cream truck sounds outside at 3am. Or seeing the face of an "alien" standing next to my bed.

    Hopefully your experience was just a trick of the mind!

    I am glad I am not in the dating game at this point in my life. I know I very easily could have been an anxious wreck of a hermit if I was completely on my own. Hopefully not a conspiracy theorist, but I can't honestly say I don't have tendencies that could put me there.

    The poor relationship between the sexes is something I have morbidly kept my eyes on for a long time. I married pretty young, but I have a good handful of inexplicably single friends, both male and female. None of whom seem to be compatible with each other, or frankly even living in the same perceptual universe. They are all good people, fairly successful, and not being unreasonable in their standards as far as I can tell. But there is just some complete lack of trust or faith in the opposite sex on both ends. It hurts to watch.

    I think best case scenario is that matchmaking services and "arranged marriages" (by this I mean voluntary setups through families and social networks, nothing coercive) begin to catch on. There has got to be a way to pair up people who are at least somewhat vetted for trustworthiness and seriousness in seeking companionship, outside of the confusing and alienating social landscape we have developed, or the meat market of online dating. But maybe I am naïve to think that would work.

    Both are fascinating to me. I have also met a lot of people who are interested in both. I don't think it's a coincidence. There's something really interesting about the way we can use symbols and signifiers to encode and transmit and preserve information. Any kind of information.

    Coding requires you to say precisely what you mean. Give clear instructions. Define exactly the pieces you are working with. There is really no room for ambiguity, and there's something really satisfying to the logical side of my brain about that kind of rigidity.

    But that's exactly why linguistics is interesting to the other side of my brain. Human language is full of fuzzy categories, changing definitions, unwritten rules, unspoken connotations, creative repurposing, borrowing, taboos... You can add dimensions of meaning with text, your voice, your eyes, the movement of your body. You can pack so much nuance into a single word or phrase; a subtle hint can mean so much more than what you are literally saying. You can intentionally encode a message so that it is NOT understood. There is infinite malleability in human language.

    This is why it's so exciting to see such progress in natural language processing. Large language models kind of blur the lines and begin to "understand" and respond to the ambiguities of the way we use language (at least in a kind of probabilistic sense). But they are also learning our programming languages. Right now, we can converse with AI models that can write (basic) code for us and with us, and make changes based on our conversational language. Imagine one day programming in plain language without that intermediary step!
