I think it’s more like sunlight energy + adhesion energy - cohesion energy, because the capillary action is also helping to lift the water but generally yes the energy is coming from a combination of the chemical forces in the water and the pressure gradient from the sunlight/heat.
Generally, yes, but in the case of trees there is also negative pressure (vacuum) exerted from transpiration when water leaves the top of the tree and “pulls” other water up behind it.
What you are describing is not osmosis, it is capillary action. Capillary action is caused by the forces between the water molecules and the molecules of the tube overcoming the force of gravity. You can read more here: https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Physical_Properties_of_Matter/States_of_Matter/Properties_of_Liquids/Capillary_Action
Briefly, the water molecules are attracted to the molecules of the tube by adhesive force. The liquid molecules are also attracted to each other by cohesive force. The interplay of these forces causes capillary action.
However, it seems that tree sap moves by more than just capillary action. If you scroll down part way in this book they talk about it a bit: https://pressbooks.online.ucf.edu/phy2053bc/chapter/cohesion-and-adhesion-in-liquids-surface-tension-and-capillary-action/
Western North Carolina 😭
Hoping to get back there soon and bring my tourism $$ with me when they are ready. The mountains are my happy place and make me feel like a kid again.
Also, bike riding (when I’m not in a conflict with cars) is giving me a lot of joy. Especially when there are other bikers about.
Acetaminophen (Tylenol) if I can’t get it under control without meds but I agree with the other posters about trying to figure out the root cause! For me, the main causes of headaches used to be hormones from the pill until I switched to a different form of birth control (IUD). Nowadays my headaches are mostly dry eye or allergy related so I keep eye drops on hand and take allergy meds and I’m down to headaches once every week or two. Staying hydrated and taking fish oil supplements has also helped my dry eyes.
Yep I get mad about this as well. Esp since my title isn’t Mrs. it’s Dr.
We always joke they should have addressed it Dr and Mr [my first name last name] but of course the real answer is they should just call people by their actual names and titles and not guess.
Lolol what kind of fantasy world do you live in? Salaried worker here and although my job isn’t 9-5 strictly if I don’t work at least 40 hours a week my pay will be docked. So I get to choose between 8-5 or 9-6 or I can work while I eat and get that cushy 9-5 life. Or if I miss work I can make up those hours by working at night. It’s a real luxury to be able to do that compared to shift work, but the hours are still being counted.
Also stop being so entitled. Most of your life necessities come from industries (groceries, power plants, gas stations, hospitals, etc) where people work on a timecard/shift basis so don’t you come out here and pretend timecard or shift work isn’t a “real” profession.
Yeah this is what happens with our kid (who, admittedly, has ADHD so maybe he’s a bit unusual). The first day or week after a cool experience he’s pretty meh about it and won’t volunteer much in the way of thoughts or feelings and then suddenly he’ll realize it was real again and all of a sudden he won’t shut up about how cool it was! Then eventually he settles down into a steady pattern of “hey remember when we did X thing wasn’t that so cool we should do it again” which is my favorite phase because that’s how I know what he really likes that stuck with him. : )
Kind of like the other poster, I can figure out how most simple mechanical things work by looking at them and can usually cobble together a solution to mechanical problems out of random stuff from the hardware store. I’m also really good at fixing simple mechanical and electrical things like bicycles, flashlights, hair dryers, fans, office chairs, etc. I’m also quite handy with a sewing machine and can fix most clothes.
More complicated things like appliances, software, etc I can’t do as quickly or easily but I’m still pretty good at hacking together solutions with the help of YouTube and online forums.
Has probably saved me thousands of dollars over my lifetime in keeping things running and not having to buy replacements, but also I lose a lot of time and space to all my “I can fix this” projects.
Not OP, but we have a bidet and a basket of cut up t-shirt cloths next to the toilet that are single-use and then go in the wash every week. I wouldn’t personally reuse washcloths for wiping out of fear of UTIs, but I’m extra paranoid.
Oh, they totally do. That’s why I’d suggest not punching a Nazi in front of the cops, even if they 100% deserved it. The cops will arrest you much quicker than they will a fascist even if you do the same exact thing.
And also definitely YMMV on whether this works at all, I’m in Massachusetts where the cops have to at least pretend they’re doing their jobs so they will typically detain Nazis if they take an actual swing at someone. Other states this might not work at all.
Nazis get worse if you don’t actively oppose them. That can look like punching them, but it can also look like actively ostracizing them by taking away their jobs, denying them participation in community events, or just straight up shaming them in public.
Pacifism only works if the other side isn’t willing to kill you. These jackasses fantasize about genociding people as a hobby, so if you think pacifism is going to work for you then go right ahead but I’ll be over here working on my defensive skills.
In many situations nazi-punching is not your best tactical decision, especially in the presence of cops. Using your words to hurt the poor Nazi snowflakes feelings works just as well and has the added benefit of potentially provoking them into getting themselves arrested if there are cops watching.
Agreed. We have kept wearing masks in specific places (public transit, crowded events, airplanes) and it really does make a difference. I never get sick from airplane trips any more, which used to be a fairly regular occurrence.
I will say, I was never able to figure out how to stop a properly fitted mask from giving me a terrible headache after 8 hours of use so I’m glad I work from home and don’t need to make the choice of mask vs comfort at work.
Bought a Eufy g30 robot vacuum because it advertised that it could climb over thresholds and it does! The accessories are cheap too, especially if you buy knockoffs. Bought it in 2021 and still going strong, no complaints after almost daily use in a home with a cat and a small child.
Thank you for letting me know this was a thing!! Total game-changer.
Can’t quote the lyrics without sharing the awesome lyric video!

Used to sing this song to my kid at bedtime but he hasn’t asked for it lately. Maybe I’ll try to work it back into the rotation.
I have a white Prius named Shadowfax so if I need to go somewhere fast I can yell “run Shadowfax, show us the meaning of haste!”
I have a “mom” sized pocketbook that I carry around and it always has the following:
If it’s sunny I’ll bring a sun umbrella and a hat, both of which can fit in the bag in a pinch. If it’s raining, just the umbrella. It’s not a perfect system but some things (especially the band aids and fidget) come in handy pretty often
Another vote for mindustry! That game is a blast.
Letting kids (and kids at heart) go wild with their imagination and dress up.
Meeting/seeing neighbors.
Eating candy.
I feel really sad for all the folks on lemmy having a bad/frustrating Halloween. I think it doesn’t have to be that way, but it does definitely take neighborhood-level effort. We’re really lucky to live in a big Halloween neighborhood in a walkable area. We saw all our favorite neighbors and met some new ones, and enjoyed all the creative decorations and costumes we saw while we were out.
But the best part of the night is always getting to see people light up when you recognize their costume. Every time I see a kid dressed as Batman and go “whoa there’s Batman!” or compliment a princess on their beautiful dress, you can just see them stand up straighter or strike a pose and it’s awesome to see everyone dressing up and enjoying themselves. I probably saw a dozen Marios tonight from age 2 to age 20 and every single one of them was over the moon when I complimented their costume.
