  • how much you can build without a complete understanding

    We’ve never actually never had one. I’d have to check the timelines but Tesla was almost certainly working on a functional, but inaccurate atomic model (Bohr). Medicine is actually a great example of all this. We are so used to just kind of knowing “there’s a bad bug or bad gene that’s making me sick”. Like you may not know the details, but you’ve got some loose concept a bunch of cells in your body are pissed off. For the vast, vasssssssst history of medicine, it was all empirical, and the thing is, it kind of worked… sometimes.

    My favorite example of “knowing without fully understanding” is Mendel and his peas. If you do a 4x4 punnet square (that gene cross thing), and look at the frequency of co-inheritance, you can track how far genes are from on another (because the further they are, the more likely there will be a swap during the shuffle). Thing is… because DNA is an integer thing (no such thing as ‘half a base pair’) it works DOWN TO THE SINGLE BASE PAIR. Mendel was accurately counting the number of freaking base pairs separating genes without knowing what a base pair, or indeed even really a molecule, was.

    Tesla would have lived to see some absolutely nutty stuff in physics. Boltzman, Einstein with relativity, it must have seemed like pure madness at the time.

    So yeah, we discover new and interesting stuff all the time. I personally think that some of the weird quantum stuff is going seem as rote in the future as germs do to us now. As in, the same way any lay-person shoved into a time machine would at least be able to give the basics to a medieval European, someone from the future would be like “well I don’t remember much about quantum tunneling, but…”.

    And that’s all before getting into some of the bizarre things going on in math itself. Be careful if you look into that stuff though, it’s easy to fall into the “Terrance Howard” style rabbit hole. Suffice to say there is some really interesting and unexpected implications we’re discovering, but if you don’t have a solid grasp of theory, it is easy to be led astray but sources that want to gloss over details to talk about a conclusion that isn’t actually supported. It’s like if you tried to explain time dilation to an ancient Greek, and they excitedly hopped on their fastest chariot thinking they could “fast forward” to the future, because time moves “more slowly” for you when you’re going faster, right?



  • You’re wrong. You’re so wrong. The warm light of everything good in this world has clearly never warmed your face nor caused the roaches to flee from the empty, echoing cavern that holds not but rot, mold, and regret where a brain is sorely missed. I pity you, your parents that birthed you, and all of humanity at large for now knowing a person could be so misguided. I pray for your strength on the inventible day when the faintest candle of reason illuminates the vaguest shadows of comprehension, and you may finally witness your errors, so long called accomplishments, as they loom over you like demon gods eager to drag you to hell in a cage you’ve spent a lifetime creating for yourself.

    7+9 is dope though.



  • Thrilled you asked! So yes: Treatment is always required, but the final destination of the treated water can vary. For instance, in a lot of places they may have municipal water TO a home or business, but that may be discharged to septic, as opposed to the river. Also in a lot of areas, water may be taken out of an underground aquifer (either by private well or a municipality) but when treated it may be discharged into a river or ocean. That can create problems because if you’re near the coast, the empty space in the aquifer may be filled by salt/brackish water that can lead to salinity rises in the aquifer. To solve that some places turn to “ground water recharge”, which is just a fancy way of saying “we built a big well to put it back in the aquifer”.

    Increasingly, you’re seeing some places essentially sell their treated water. Santa Rosa CA, for instance, built an entire pipeline that goes from their treatment facility to another municipality to be injected into their groundwater.

    So yes, everywhere treats it, but the final destination makes a difference. Las Vegas (or anyone else on the river) only gets credit for what goes back into the river, so any evaporation etc is a problem. It sounds trivial, but there is a reason those other strategies exist. It essentially doubles every pipe, limits where you can park a treatment plant etc. Vegas also does some great grey water re-use. That essentially means it doesn’t go “back” but can get used many many times, limiting the initial draw.

    Wastewater is funny because it’s far from rocket science, but the numbers to implement any of it get staggering very quickly.

    My dad was a farmer. I AM AN ORPHAN.

    Edit: Ok, I feel bad. But like… I know one dumbass with a cough that won’t go away (7 years and counting) because they wouldn’t effing listen to me about DE, another who rolled his tractor on to himself and died. Don’t take it lightly man. The bill always comes due. We all do what we have to, lord knows I’ve done some dumb shit, but it ain’t cute to dismiss it.


  • That and post-scarcity doesn’t mean “zero scarcity”. Like if someone wanted to create a picard funkpop the size of a planet, I don’t think they’d be allowed the resource budget.

    It’s like how it doesn’t matter where you live, if you want to buy on the silk road, you need bitcoin. Presumably even the federation can’t just make latinum whenever they please, or we wouldn’t see them haggle with it. Although, it would be fun to see that they could and just take the responsibility of not crashing non-federation cultures entire economies very seriously, either out of respect or treaty.

    Damnit, I want a LD episode where the crew is frustrated and desperately wants to just “buy” their problem away but can’t because an economist at command says it’ll mean they have to rescue all these non-federation colonies that are currently self sufficient. Come to think of it it’s right there with the “you break it you own it” concept of the prime directive.






  • Absolutely. But that also skirts the fact that the economy, globally, depends on rent in Manhattan being high. Like as shitty as the rent is, the bigger problem is how much of that “you’re paying someone else mortgage” thing is true and wayyyyy over optimized.

    Roll into that the fact that the whole rising/uninsurable thing in Florida is come for literally everywhere near sea level… Which is every major metro in the usa… It’s a problem.



  • Look I’m happy for you, but I’m from an area where this is all very different from where I ended up.

    Im sorry, but I do think thats a massive part of this conversation. There are plenty of places where housing is still affordable, but relocation is a thing, and more importantly, so is the tie to pensions funds and investment in major metros.

    All of that to say, I’m glad to say it worked out for you and yours, but it’s just not relevant in this conversation, at least as long as social security requires people changing tires in Atlanta Georgia.
