  1. https://imgs.xkcd.com/comics/nerd_sniping.png So this XKCD comic got me thinking... can the resistance of an electrolytic solution in water can be modeled as infinitely many resistors of infintesimal resistance? After all, the distance between the ions of electrolyte is a discrete quantity, but so is the number of said ions; or the number of water molecules between them; and we still model these things as continuous fluids. So obviously the resistors are in parallel; there are pseudo-infinitely many paths they can take. But no matter what path they take they have to jump between ions several times, so it's also in series. Is there any formula that could account for the combined series-and-parallel nature of a circuit through an electolytic solution? . . . Why yes, I did dream last night that I was caught in a thunderstorm with the car windows only partially rolled up, how could you tell?
  2. Encouraging alternatives to meat until we improve our healthcare system then sounds like it's a good way to make a dent in climate change and new pandemics alike.
  3. Got it, thanks! Speaking of The Simpsons... DISCLAIMER: I would not try this at home. NOR at any convenience store, for that matter. However, it reminds me of my curiosity about the issue of cryonics. I'm not sure who to believe on this issue. There are those who claim there are ways to survive being cryogenically frozen, if society would invest in them. Others dismiss it as hopeless. Are the former just wishfully thinking? Are the latter just trying to stop cryonics from cutting in on religion's afterlife action? If I found a professional service to freeze my body, would it be safer to do it immediately after death, immediately before death, or significantly before death in the context of some terminal illness or whatever? (Obviously I'm not going to cut drastically short whatever life I have now just on the offchance of being revived later.)
  4. Man, so many of the things I thought were no-brainers were a hell of a lot more nuanced than I thought. Very well, then. So what's the real solution to the current forest fires? More prescribed burns? More permanent firebreaks? Or just leaving California permanently and putting a giant pot of water over it hoping the boiling will make it pay for itself?
  5. Once again, California is on fire. Apart from the threats to property and safety, that's a lot of chemical energy in nature that is being squandered on a fire that isn't occurring underneath a boiler to boil water for food or electricity. I wonder, now... if society were to hire more of the recently-unemployed as loggers, and have them cut down enough trees that the wood could be burned in lieu of fossil fuels, (and/or be converted to paper and used as such before being burned) would this double as a way to make forest fires less severe, by the fact that there are fewer trees available, per square kilometre, to catch fire in the first place?
  6. But in many smaller cities, where space is not as limited, two-way streets are still the norm, not the exception. Might lives be saved in the long run if we switched to one-way and took away the "basic human judgment" factor on when/where it's safe to turn left?
  7. So long as two-way roads have a grid structure, every intersection will include an option for turning left a green light. And every time a driver makes a judgment call on whether or not it's safe to do so, this risks getting them killed. I'm just wondering, wouldn't one-way streets create fewer options, per intersection, on which way to turn? For instance, if a north-heading street met an east-heading street, the north-heading cars could only turn right onto the east-heading street, not left. The east-heading cars could only turn left onto the north-heading one, sure, but you could also reserve one lane for traffic that is "joining" the street, such that they only merge into the traffic when they've caught up. Is there anything to go on as to whether or not replacing our existing grids of two-way streets with grids of one-way streets would constitute a net improvement in safet?
  8. Incidentally, I'm type 1 diabetic myself. So frequent eating of sugars and starches without protein to go with it contributes to type 2 diabetes even if the person eats in moderation and/or exercises to burn it off?
  9. I hear of dispute on the nutritional value of protein. Some say it's good for you and helps sustain sugars and starches for longer periods of time; others say it inhibits calcium absportion and Google suggests the truth is if nothing else in the same general direction. If the issue were the need to sustain sugars and starches for longer periods of time, would it be comparably healthy to eat sugars and starches in more frequently, but in smaller portions, such that the sugars and starches are sustained by the fact that you're eating them a little bit at a time?
  10. So last night I threw away some aluminum foil. It was in contact with food I was using it to keep warm, I didn't think I'd have much use for washing it and saving it, and I thought nothing of it until afterwards. I just realized... if there were some program to collect everyone's pre-washed aluminum foil, and/or wash it after collecting it, it could be arranged in an increasing variety/size of concave shapes, be used as a solar collector, and boil water, whether to distribute energy directly as heat, or to turn turbines and generate electricity. So why aren't we doing this? Have the fossil fuel and nuclear industry lobbies bribed politicians into not going for it or something? How expensive can it be to arrange aluminum foil in a concave shape, or find an absorptive, water-storing material to put at the focal point, especially compared to the lengths a nuclear or fossil fuel power plant goes to for the same water-boiling turbine-turning purposes?
  11. At this point, it's a thought experiment, though if it goes anywhere I'm considering writing my representatives about this. I want to impede waves because a lot of boats, even boats going through narrow straits in the ocean, encounter rough waves. I want to cut down on seasickness, but I don't know what will do the trick against ocean waves and ocean currents. Does it depend on whether the water is shallow or deep?
  12. So I'm just wondering, short of building an outright bridge, what would it take to impede waves travelling through a strait? If one were to build barriers around the strait, would floating ones be adequate, or would they have to extend all the way to the ocean floor? Would they need to be on both sides, or would just the one upstream from the highest waves be enough to block out those particular waves?
  13. Yeah, convection sounds like it could only do so much good if there is an actual difference in dewpoint to allow sweating to help. Just so we're clear I'm referring to dark clothing in a hypothetical circumstance where all other considerations are already addressed. (Eg. Taking public transit everywhere you go, or not going out at night except through walking trails to which motor vehicles have no physical access at all, let alone lawful physical access, etc...)
