I assume that the submarine producer gives stats like empty weight from which the current weight can be calculated.

However, weight isn’t the important thing in a sub. It’s the weight to volume ratio, or buoyancy.

A sub sinks when buoyancy is negative and rises if the buoyancy is positive.

There are three common ways to achieve the changing buoyancy: the most simple one is a vessel with positive buoyancy adding droppable weights until the buoyancy is negative.

Other ways are a neutral buoyancy vessel that uses it’s engine power to push itself up or down. Or a vessel that can change it’s buoyancy by filling up tanks with water (to reduce buoyancy below neutral) and blow them out with air or other gases lighter than water (to raise buoyancy above neutral). A combination of several methods is also possible.

Thank you, I didn’t consider that he himself could have politicized sexuality first.

In that case it sounds more like a “rules for thee, but not for me” thing, which makes perfectly sense to point out!

Sorry, I am not from the US. So this guy consumed porn. And what? Relax people!

Might sound weird to prude people, but most politicians had sex before! Some may have kinks! Why do people care about other people’s sex life, if they aren’t attracted to them?

And what has this to do with a community called politics? I don’t get it.

Edit: wow, many replies! Thank you all for educating. If this man is saying people shouldn’t consume porn, then yes, you are all right and it’s a controversy that makes sense to shine some light on. I didn’t think about that.

It would not, though. I assume your glasses to have a larger surface than your eyes. Additionally, eyelash do are real good job in filtering the air in front of your eye.

Source: was wearing glasses for 25 years before I got my eyes fixed 7 years ago.

I use mosquito coils, they are very effective.

I also have an electric bat, although it’s more for the phycho fun of killing than helping reducing bites. They are just too many.

I tried lemongrass as a natural deterrent but had the impression it made no difference.

What works best for me is: slapping those you can while not caring about the rest. Because once you start to scratch it’s a vicious cycle, so I don’t touch stings and usually then forget about them shortly after.

Maybe they are different. I live in Asia. From what I heard there are many mosquito species, but the majority not blood sucking or at least not human blood sucking. Only few species carry disease, if I recall correctly.

To be fair, when I’m preoccupied, I also don’t feel them always. Or I feel them but my hands are busy, so I can’t slap them. I often have this at night, when I’m playing PC games and my feet get stung up. It’ll be like “ouch, my foot! Gotta slap that mosquito, but first I finish this in game. And then this.” Procrastinating until it’s too late.

I believe ankles are prime for them due to thin skin.

One mosquito died, writing this comment.

I disagree. I live in mosquito land and get bitten a lot. I’d say the majority of mosquitos biting me, I feel when they land, before they bite. Probably half of those I can either slap or miss and they take off again and try again. There are some spots though where I don’t feel them land. The annoying ones are those I feel touching me but they don’t land, they just fly around. Those are hard to slap.

Unrelated question: does anybody happen to know if the biting time matters for transmitting disease?

2 mosquitos died on me while typing out this comment.

Incredible poor title. OP please add a sentence or two explaining the article.

I’ll start of doing that so other people don’t need to blindly click on a link that could be anything.

It’s about a welsh coal mine that got closed (not sure if because of environmental reasons or because of less demand) and then after rains turned into a toxic lake.

Article is questioning if the toxic lake and coal imports are any improvement environmentally compared to extracting coal locally.

I think it’s not asking the right questions. So there is a toxic lake now and maybe it’s worse than a coal mine, but that shouldn’t lead to the conclusion that the coal mine was maybe less bad. Instead it should come to the conclusion that companies need to be held responsible and can’t just abandon sites like that. Maybe they need to fill in some land or I don’t know, but their mess is their responsibility in my opinion.

I haven’t read the article. Dumb question anyway. Yes, AMOC is approaching a tipping point, that science has been public since years. Yes, AMOC has already slowed down some dozen or more per cent.

And while we here answering the same questions as always: yes the climate is changing, yes climate change is also occuring naturally, however this one is human made and yes, the outlook isn’t good at all. No, we shouldn’t continue burning fossil fuels to feed our energy hunger and yes, we need to do something now or better yeaterday. And no, asking repetitive questions isn’t action enough.

Edit: excuse me. I got a little emotional. Education about climate change is good. I’m just a little tired of reading the same stuff since decades I guess, while at the same time we continue to burn more and more fossil fuels.

Another update: Interesting Youtube video about this topic.

From the article:

In 2020, new regulations required the shipping industry to use cleaner fuels that reduce sulfur emissions. Sulfur compounds in the atmosphere are reflective and influence several properties of clouds, thereby having an overall cooling effect. Preliminary estimates of the impact of these rules show a negligible effect on global mean temperatures — a change of only a few hundredths of a degree. But reliable assessments of aerosol emissions rely on networks of mostly volunteer-driven efforts, and it could be a year or more before the full data from 2023 are available.
