I guess the question is, is ripping up a golf course more or less antisocial than having a golf course?

That’s a much more interesting comment and link. Hopefully the production batteries do better than the trial run. We will see soon enough.

Wild claims? “’We did this thing in the lab.’ It could be a breakthrough provided they can scale production.” The only thing that would make this a wild claim is if they didn’t actually do what they said or if it didn’t work like they said. They didn’t even claim this could be commercialized.
Also, Professor Zhao works at Western University, in Ontario, Canada. Here’s an article about this same research on their website.

Well, the same applies to social services (welfare) and education, and the rich and powerful already know all this. So why do you think they don’t want us comfortable, educated, healthy, and secure?

Probably closer to 20 pounds if they are awarded the full amount, and the general rule seems to be that the lawyers get about 30%, but the overall sentiment of your statement is correct.
- Comment on If a Space Elevator became a reality, wouldn't the cable act as a kind of wick for all of the unfiltered radiation from outside our atmosphere? 2 weeks ago:
It requires more material and financial resources, but isn’t necessarily harder. Transmitting energy effectively to reduce heat, or managing the excess heat starts running into some pretty tough limits of physics. Most of the issues with spinning habitats are engineering problems within the capabilities of our current technology level and materials science. It’s just super expensive and has terrible ROI for now.

How is it a bad analogy? You seem to be treating it like a scale model, which i don’t think was the intention. Moreover, most of the effects map over fine.

There isn’t a requirement for a Dyson shell to transmit energy. You could just envelope the sun in habitats that use the energy they collect locally and that would meet the criteria of a Dyson shell (and a K2 civilization).

It needs to weigh enough that it counters the momentum/drag of the cable plus the net of whatever mass is going up. Keep in mind that cars going down add to that overall value while cars going up subtract. Also, the general opinion is for the station/anchor to be slightly above geosync so the net effect of the orbit on the station is to be pulling away from the earth (there is some wiggle room depending on how robust your earth anchor to be and the mechanics of your tether with respect to tension vs. compression, but most models plan for a little net lift). In other words, you also attach to an anchor on the earth (which could just be a chunk of bedrock) to counteract that net force. Since the net force of the tether (not counting the earth tether) would be away from earth, any net loss of momentum would be regained from the earth’s spin (which happens whenever we launch a rocket right now). You could also have a spool at either end to maintain the desired tension on the tether while accounting for slight elevation changes due to net momentum loss or gain. On top of all that, the space anchor mass isn’t really dependent on the mass of the earth so much as it is on the net amount of mass being lifted or lowered to the earth and the amount of time you want to wait to return to it’s desired orbital altitude. And finally, if the tether was severed only the part whose center of gravity was below geostationary orbit would actually fall to earth - the rest would leave orbit.

Your inhibitions are also, to a degree, part of what make you who you want to be. Not excusing him, certainly not defending him, but sometimes a little inhibition is a good thing.

English has at least 5 (French, Germanic, Greek, Latin, Arabic, doubtless more) and it’s up to the user to know which is used in any given context. Or not. It’s really kind of stupid.

Part of how scissors are design is for there to be a natural tendency to pull the blades together when you press with your thumb.
On a reladed note, if you’re left-handed, get a pair of left-handed scissors. There are two reasons for this. First, you will be amazed at how much easier it is to cut with the correct scissors. Second, you can have your friends who don’t think having the correct scissors is a big deal try them and see how wrong they are.
- Comment on I need to vent about plastic milk jugs 5 weeks ago:
Well, I’m in Canada, so the standards are already higher as far as quality goes, and our regulatory agency is still in place for oversight.
- Comment on I need to vent about plastic milk jugs 5 weeks ago:
Option number 4. The sanitary standards for packaging milk are very high in North America. This drastically reduces the risk of contamination after pasteurization, which allows our milk to last quite a while. It isn’t as sterile as UHT milk, but it tastes more natural.
- Comment on I need to vent about plastic milk jugs 5 weeks ago:
They had milk in 1.3 L bags (sold in packs of 3 for 4 L) in Manitoba about 35 or 40 years ago.
- Comment on How much earth would compress and expand if all of it was 50°C 5 weeks ago:
Given the quaint physics of circles, the expansion of a ring of silicate around the earth would be quite noticeable. C = 2×pi×r, which can be converted to r = C/(2×pi). Plugging in those two values gives us
40000/(2×pi) = 6366.1977 km
40008/(2×pi) = 6367.4710 km
So, taking this ring from 0° to 50° would cause it to rise 1.2 km into the air, assuming it kept its integrity.
A simpler way to write this is
(40008 - 40000)/(2×pi) or 4×pi.
A tiny difference, relatively speaking, but a quite notable difference given the context.

- Comment on What’s up with Myrrh being more prevalent? 1 month ago:
Wikipedia lists about 5 other uses, some of which would probably still be relevant today if we didn’t have cheaper ways to make perfume. Silly wise men, giving expensive, light, easily liquidated assets to people they believed were going to be fugitives. As well as some much heavier, but very easily liquidated assets. Poorest choices imaginable.

- Comment on Which of frankincense and myhrr is more pricey? What even are they, respectively? 1 month ago:
Myhrr was also used in incense, balms, etc. They were great gifts for anyone for the reasons you listed, especially during a time when people of that nationality had been ordered to travel possibly great distances and you believed the people you were giving the gifts to would be fugitives.
- Comment on My Indigenous Ancestors on Christmas Day 1 month ago:
Yeah, I’d hope ancient enmities wouldn’t lead to modern problems, but it’s funny watching some people treating the indigenous people’s like a single entity, or like there weren’t fights between groups.

- Comment on What dude in your life has the most Michael Landon-esque full head of hair? 1 month ago:
I doubt I’ll ever be bald, although I expect I’ll be pretty thin in my 70s and later, and I haven’t really cared one way or another about baldness. I got my first grey hair in my teens and it hasn’t stopped, and I don’t care too much about that, either (it was cool when I had the flashes of grey above my ears like Reed Richards in the old comics, which I thought looked so fake). My beard is shit, and I don’t care. I shave because it looks like shit, tho. It’s great if we can accept what we are.
I’m glad you’re happy with your skullet and epic beard.

Fun fact, copper, brass, and silver are anti-microbial, so a lot of old-time door handles were anti-microbial. Odd coincidence, isn’t it?
