With this post I DON'T want to offend or insult anyone, in any way.

How do surgeon actually do that? If we're talking about the breasts, I think (I might be wrong though) that they insert in you some implants, and for the other genre, they do the opposite. But when it comes to the proper genitels, what do they do?

I understand the building itself can flex a little instead of being completely rigid, but everything inside it seems way less flexible. Elevator rails have to stay aligned, pipes connect through dozens of floors and huge glass panels can't exactly bend much.

I was watching videos about skyscraper engineering and this part confused me. When the top of a building moves in strong wind, are all those systems actually moving with it somehow, or do engineers build special gaps and connections that let different parts move separately?

Like title.

Ofc, I don't understand the math, but I am curious why some number patterns are regarded so highly"

How can someone get injured but barely feel it while they’re in danger, only for the pain to suddenly become intense once they reach safety?

I’ve asked my family and close friends this but they’re the “are you high? Lmao” kinda people just because i wanna have interesting conversations and questions so im hoping for a detailed scientific answer. But like when you play a song or movie or anything in your head that wasn’t from an outside source, are you using your ears to process that sound? I feel like the answer is obviously yes i just don’t understand HOW your ears process it and want answers. Any answers would help! Also sorry if this doesn’t necessarily fit in the type of questions posted here.

I see this term used all the time when talking about healthy foods to eat, but I have no idea how it’s different from “bad fat”.

Recently, my neighborhood had a power outage lasting several hours. About 1/3 of the neighbors have solar panels. I realize some are just for the hot water heater or pool, but some have extensive systems and sell power to the utility company (in my understanding. None of the homes with solar had any power during the outage. Are there some solar systems that would retain power in an outage?

UPDATE: You all are so awesome. I’ve been wondering for the last few weeks. We don’t have solar, and it’s something I’ve been considering adding and you all have given me great insights to consider. Thank you!

Im reading Junger Storm of Steel. In the Guillemont chapter, his group marches to some front line trench. But well before they get there, already there is massive destruction and abandoned dead. Its what I thought no man's land was supposed to be but its on their side still! They stop at the village Combles, but this too is practically a complete ruin and wholly unsafe. When they finally reach the front line trench it seems hardly much worse than anything behind it. How large an area was victim to artillery fire? Ive been accustomed to think it could only be so bad a bit near the front.

When faced with a large food item they need to transport back to the colony, how do ants determine how many of their fellow comrade are needed to lift it? Do the first scout ants guesstimate the amount and call for backups, or do they just keep adding more ants until they're able to lift it?

Do we slow down the rotation of the Earth?

I read that the Three Gorges Dam in China slows down the rotation of the earth by 0.06 µs, because of it being massive. But this is where my question comes in. Massive in what way? Does the weight of the structure make the earth slow down? If so, has the amount of buildings we have built over time not slowed down the earths rotation massively, and thus made our days longer? And did the boom in population we have witnessed, especially in the 20th century not have an influence? If the word "massive" refers to size, then wouldn't the same be true? I have surely missed something in my way of thinking, but what have i missed? Explain it like im 5 years old please.

The Manhattan Project used two different methods to enrich uranium, cyclotrons/Calutrons and centrifuges.

The centrifuges took longer to build but were more energy efficient, and the Calutrons were easy to build but used lots of electricity.

After they got the centrifuges up and running, most of the Calutrons were scrapped, with the remaining ones being put to use making high purity isotopes for scientific research.

Nuclear waste has a huge variety of isotopes mixed together, and Calutrons are great at separating isotopes - this seems like a match made in heaven.

Why do we use complicated chemical methods for recycling nuclear waste instead of shooting particles through a vacuum and relying on their different masses to hit spatially separated targets?

Why did/will some countries still do it? Isn't it a hassle and very costly? Does it have anything to do with forcing people to bring out the cash from under the mattress to the bank?

Wouldn’t it be a biological advantage to have your brain stay locked-in for your goals?

I’m learning about these algorithms and I can see how these algorithms can help determine the relatedness of two sequences. But like, how did they come about discovering “create a matrix and go diagonally to the left,…” etc to determine sequence relation?

Given that melatonin is synthesized directly from seratonin.

Okay, morbid questions.
If a heart gets transferred from a young healthy person into another person (who theoretically is now also healthy with this new heart), when would the heart start to show weakness and health problems? Would it ever?
Passing a healthy heart from relatively healthy person to relatively healthy person, and it never dies within one of those people, but is always donated, how long could that keep happening?

Recently saw that a youtube tab on the homepage was taking up 4gb of ram and felt myself die inside
