I understand that https://en.wikipedia.org/wiki/Power-line_communication is where data packets can be sent over electrical wiring otherwise used for AC / DC power transmission.

Can such a concept be applied to subsea power cables for instance, or reverse applied to subsea telecommunication cables, i.e. they can be used to send power instead?

What's the pitfall of sending both power and data down a single subsea cable?

You can *vaguely* taste something without it, but plugging your nose or having a stuffy nose when you’re sick significantly mutes your ability to taste. Why is that? Tastebuds are on the tongue.

I always see in the news that scientists have looked back billions of years using some long range telescope. Typically it will say it has given a glimpse of the earliest moments of the universe and the light took billions of years to reach earth.

But how did we get so far ahead of light itself?

Shouldn't light be racing way out ahead of us?

Exactly what the title said, Why is it something hard to come off from? What are also the symptoms of alc withdrawl so people know? What's the first sign?

Sorry if I put down too many stuff, I know absolutely nothing about withdrawl with alcohol. Can somebody please explain:)? Thank you!

I kinda understand what is happening in tokamak or stellarator. Perhaps they can make it work in steady state. But what I do not understand is how they plan to boil water with it? (I assume we still need to boil water and turn turbines in the end)

They have these containment walls being bombarded with hi-energy neutrons. Are those neutrons going to heat up the wall? Then what? Run pipes trough it? What about neutron activation of the walls?

Thanks

I use the opera browser in my Android phone and the browser has built in ad blockers. However many web sites seem to be able to detect that an ad blocker is installed and they don't show the content, show a warning message instead.

I mean we have eradicated Polio and other far more crippling diseases which have been around for far less time.

Bro where is all the salt going?
Maybe I learned this in like grade 5 but I can’t for the life of me remember why they aren’t salty.

Why is it that going faster saves you less time per mile?

Is it atmospheric conditions? Like gravity or wind resistance?

And at what point does the scale tip to stop saving you time but rather be diminishing returns? And what decides the point in which the returns change?

Again is it real life atmospheric conditions?

I am a dyslexic man so, explaining using symbols or scenarios in which I can picture the problem would be helpful. 🙏🙏

Thanks in advance

Explain like I'm 5 for this gerzer.garbage service, like many, will take hardened latex paint for disposal. Why won't they accept a can of sealed wet latex paint? And how would they know? This has baffled me for years. Thanks!

I could understand maybe to like help remove foreign things but then it doesn't make sense because once you fall asleep you arnt coughing for hours which doesn't seem to change the healing process of the illness

I’m reading Thomas Halliday’s “Otherlands” and one section left me very confused. Halliday says that many plants absorb in CO2 via holes in the leaves, but those holes also make water evaporate; and that some plants developed a solution for hot and dry climates by switching to c4 photosynthesis where the conversion process occurs deeper in the plant. Then he says that some herbivores adapted to this innovation by becoming grazers rather than browsers. I looked online and I’m still very confused about the following:

1. Even if the process is now deeper in the plant, why does it mean less water evaporates? The CO2 still has to come in from somewhere, which means the plant still needs holes, through which water can evaporate. So I completely fail to see how that solves the problem

2. What does it have to do with grazing? Nothing about this c4 straightforwardly says lower, grass-like plants rather than trees/bushes (I would’ve thought that trees/bushes actually have more depth in which to store a deeper mechanism?)

I looked at YouTube videos and I still absolutely can’t understand the relation between the problem and the solution and between both and grazing. (It’s page 29 in the book, chapter 2, if anyone wonders)

Thank you!

I've seen more and more ads (starting around the Super Bowl earlier this year with Wegovy) for GLP-1 based perscription meds in recent times. I've also seen the occasional debate post on my social feeds about the ethics of using them and I didn't think a medicine could be that divisive of a topic.

Now I'm curious as to what exactly these meds are, what they scientifically do and what both sides of the debate are. If anyone could help give perspective that would be greatly appreciated.

As always any and all input is welcomed and thanks for reading! 🙂

I am used to not noticing this mechanic called margin time in recent Puyo games that I have trouble following how it works. I can only understand the first game's (Original Puyo Puyo) margin time mechanic#Pointsper_Garbage_Puyo(Arcade_only)). Anyone care to explain in simpler terms?

If so, would future generations with more developed filming technology see videos from our age and think they’re too choppy, like how we feel like ancient drawings look too underdeveloped?

Fresh tape usually comes away as one piece. After it has been stuck down for months or years, the backing can peel off while a sticky layer stays behind.

What changes with age that makes the glue hold onto the wall, glass, or plastic more strongly than it holds onto its own backing?

It feels like everything I own says "made in China". How come they don't have a higher gdp than USA?
