| Posted: 15 Oct 2021 05:13 AM PDT This is the story: https://www.theguardian.com/business/2021/sep/15/fire-shuts-one-of-uk-most-important-power-cables-in-midst-of-supply-crunch I'm aware that power generation and consumption have to be balanced. I'm curious as to what happens to the "extra" power that a moment before was going through the interconnector and being consumed? Edit: thank you to everyone who replied, I find this stuff fascinating. [link] [comments]  |

| Posted: 14 Oct 2021 05:52 AM PDT Started thinking about this after watching this video: https://www.youtube.com/watch?v=wfYbgdo8e-8 It talks about the effects on a person after having a surgery to cut the bridge between the brains hemispheres to aid with seizures and presumably more. It shows experiments where for example both hemispheres are asked to pick their favourite colour, and they both pick differently. What I haven't been able to find is an experiment to try have a conversation with the non speaking hemisphere and understand if it is a separate consciousness, and what it controls/did control when the hemispheres were still connected. You wouldn't be able to do this though speech, but what about using cards with questions, and a pen and paper for responses for example? Has this been done, and if not, why not? Edit: Thanks everyone for all the answers, and recommendations of material to check out. Will definitely be looking into this more. The research by V. S. Ramachandran especially seems to cover the kinds of questions I was asking so double thanks to anyone who suggested his work. Cheers! [link] [comments]  |
| By how much could we lower sea levels if we filled the Qattara Depression? Posted: 15 Oct 2021 02:57 AM PDT I am aware that rising sea levels aren't the only issue with our ongoin climate crisis, but I was wondering if filling large swaths of land (like the Qattara depression) would have a noticeable impact on sea levels. So assuming we build a canal and manage to fill it completely, would that have an impact on sea levels? [link] [comments]  |
| Posted: 15 Oct 2021 04:22 AM PDT Lagrangian and Eulerian approches are both used to describe a body movement, but most of the time they give different velocity expressions and also magnitude: one could be zero and the other different than zero. How could this be possible given that they represent the same object in motion? [link] [comments]  |
| How do you calculate energy losses in long distance power lines? Posted: 15 Oct 2021 03:52 AM PDT I've been looking in the concept of whitewashing a bit recently and came across articles mentioning companies buying electricity from power plants in other regions that require multiple stepup/down transformers. And Over 1000miles of Power lines combined. Is there a method to calculate this? Production -> 300 miles 400MVac mv -> 400mile 400MVac- >200miles of DC cable -> 400 miles 400KVAC -> 20/40 kv destination. I assume there is significant losses in a setup like this where power isn't brought from the nearby production facilities. I also know this isn't how the power grid works but it's the way that the green energy is defined. [link] [comments]  |
| Do the atomic subshells in a given shell have different average radii? Posted: 14 Oct 2021 11:03 PM PDT Forgive me - I never took P-Chem. It struck me that if the primary driver of difference between the shells was the principal quantum number (n), then the azimuthal quantum number didn't seem to explain the difference between the energies of subshells in the same shell (3d > 3p > 3s, e.g.) for the same reasons (where U = F * r), unless it is indeed the case that the increased number of electrons in that subshell caused a mutual repulsion which caused a net outward Force.

| Were Henrietta Lacks’ cancer cells unique? Posted: 14 Oct 2021 12:12 PM PDT I read an article that said the cancer cells they collected from her without her consent were the first and only cells ever to have been found to multiply outside of the body. Is this correct? [link] [comments]  |

| What keeps magnetic domains in alignment? Posted: 14 Oct 2021 10:22 AM PDT In the production of permanent magnets, it is known that heating the metal up and then slowly cooling it down in the presence of a large external magnetic field will align the domains and they will stay in line creating a permanent magnet. What is it that stops the domains from scattering after they are cooled down in the same way that the domains scatter after a normal piece of metal is removed from a magnetic field?

| Posted: 14 Oct 2021 12:51 PM PDT If the antibody concentration is not a reliable factor for measuring immunity against a certain disease, why is it used as an argument for a third booster vaccination against COVID? I keep reading in the media how the antibody concentration declines over time, and therefore we need to vaccinate especially vulnerable groups for a third time. But to my understanding, the antibody concentration will go down, no matter what. Won't it? [link] [comments]  |

| Where does the sugar in fruits come from after they become ripe? Posted: 14 Oct 2021 08:00 AM PDT When you go to the store to buy mangos or bananas they come unripe and they are mostly sour and are not very sweet, though after a week when they become ripe they are much more sweet than when they were unripe, my question is whqt happans that makes them so much more sweet?
