  • It’s mostly function for cameras like that. The lense stacks for cameras these days is some really cool stuff crammed into a really tiny package. I don’t know the exact function of each camera, but they are collecting a lot of light to focus on a small camera sensor and are able to achieve some amazing results for various focal depths.

    More lense with bigger holes equal more light, usually.

    The biggest ones are going to be your generic filters which need big enough to keep the rings from interfering with the field of view.

    There is some super cool engineering packed into those thing, but mainly because of their size.


  • I would try and light it outside, but with a long stick (like a wooden skewer). There is a high chance that those are O2 bubbles, if you were trying to make some Sodium Percarbonate which is a common additive to laundry detergent anyway… It’s supposed to be equal parts mix, but I suspect the excess of hydrogen peroxide is intentional as to have the best chance to convert all the sodium bicarb and still have plenty of liquid to soak something in. (Just a guess. Chemistry can be a weird science sometimes and I think there were a few reactions that could of happened here.)

    Consumer grade hydrogen peroxide is dirt cheap, and so is the baking soda. I dunno if you saved money and a made a more effective solution for what you are trying to accomplish. A spoonful or two of regular laundry detergent may have masked smells a little better. Dunno. I like science but I also like efficiency, so whatevers! (Experiments are fun.)

    Well, it’s kinda cool to look around and also realize that much of what you see likely came from multiple supernovae and/or kilonovae. (Huh. I have never needed to pluralize the word ‘kilonova’ before. Meh… It looks cool with the ‘e’, so I’ll leave it.)

    Eventually, our atoms are going to get blasted out across the universe again to maybe become part of some other planetary system, before it eventually gets destroyed or sucked into blackhole and is evaporated as radiation. This might not even be the first universe our bits have been a part of …




  • I would normally say this is a parental issue. However, the quirky combinations of vitamin b, caffeine, massive amounts of sugar combined with whatever else is even slightly rumored to boost energy should be, at minimum, slightly regulated for youth.

    I am not doing deep-dive research for this comment, but I would speculate that the above drinks are simply not healthy for developing bodies and brains.

    I also suspect that the biggest issues are with lack of moderation.



  • Most of TNG painted a picture of a perfect utopian Starfleet and how humans had grown up, like you say . (Obviously, humanity is never perfect but the messaging is fairly clear: They try.)

    I can chime in more about VOY and ENT though…

    VOY is my favorite and also when you start to see a little more of humanity in Starfleet. We learned a few things like: The Prime Directive/Temporal Prime Directives were always just suggestions, murder could actually be justified, you will never get promoted past ensign if you play the clarinet and chemical addiction is still a key driver in human decisions and behavior.

    ENT is just the human transition out of a military focused race to a race focused on exploration. (I am not sure why Archer always seems to have serious case of constipation, but it is what it is.)
