| Why is my pot hydrophobic where it contacts the range grill? Posted: 18 Oct 2021 02:47 AM PDT This is the pot in the sink after being washed and rinsed. You can see the water collects in a pattern that matches that of the range. The pot is steel, I imagine the range is as well. The bottom of the pot is flat. The pot is cool. [link] [comments]  |
| How do electrical grids manage phase balance? Posted: 17 Oct 2021 11:25 AM PDT In the US most residences are fed by single phase power, usually via a split-phase transformer. Somewhere upstream of this transformer, presumably at a distribution substation, that single phase is being drawn from a three phase transformer. So what mechanism is used to maintain phase balance? Do you just make sure each phase supplies about the same amount of households and hope for the best or is it more complex than that? [link] [comments]  |

| How long do the fissile materials in nuclear bombs remain active enough to detonate? Posted: 17 Oct 2021 10:44 PM PDT I just had a thought that Fallout has enough crazy people to see more bombs go off. I'm sure the electronics and infrastructure needed to deploy them will degrade much faster, but how long would it be before the fissile material in leftover weapons would deteriorate?

| Posted: 18 Oct 2021 05:38 AM PDT As somebody who knows next to nothing on the subject; Taking into account future technology, is it possible for a Jet Engine to breach earth's atmosphere or is a rocket engine the only possible way? [link] [comments]  |
| What’s makes a gene dominant or recessive? And how does it work? Posted: 17 Oct 2021 08:21 AM PDT Why does the blue eye gene not show when a brown eye gene is present. Does the brown eye gene delete the blue eye gene, or does it override it, does the blue eye gene just become inactive? If it does become inactive why? [link] [comments]  |
| How long does it take for oxygen in your body to cycle? Posted: 17 Oct 2021 06:47 AM PDT You breathe in oxygen, it gets attached to hemoglobin, which delivers it to cells where it gets used by cells to generate ATP, producing carbon dioxide, which gets pumped out of the blood by that same hemoglobin and dumped back in the lungs. How long does this cycle take? E.g. if you were to breathe in some oxygen 17, how long would it take for it to exit your body? Similar question in regards to water that you drink - how long does that cycle take from absorption to excretion? [link] [comments]  |
| Can dolphins really do arithmetic operations? Posted: 16 Oct 2021 10:40 PM PDT I went to a local safari park and part of the educational shows that they have there is dolphin shows where they show off what dolphins can do like how they make sounds to communicate to each other, doing flips and such. Among the tricks was they asked a member of the audience to provide an arithmetical operations (additions, subtractions, multiplications, divisions) with the limitation that the results should be 1 to 10. The trainers will then write the operation on a small blackboard, point it out to the dolphin and the dolphin will swim around and splash their horizontal fins as many times as the answer. The audience will count along with the number of splashes. There's usually two math problems presented to different dolphins. The first doplhin usually gets the answer right, while the second one fails at the first attempt then gets the correct answer at the second attempt. So does the dolphin really read the blackboard and actually did the arithmetic operations or its actually looking/listening to other cues from the trainers? [link] [comments]  |

| Posted: 16 Oct 2021 03:09 PM PDT This might be a dumb question, but the keywords involved make it hard to Google for an answer because "electrical", "shock", "nerve", and "nociceptor" connect to a lot of subjects. So what's the mechanism for feeling an electrical shock? Humans have dedicated mechanisms for perceiving mechanical, thermal, and chemical stimuli, and presumably electrical shock is just hijacking one of those, but which one? Or all of them? Or something else? [link] [comments]  |
