I’m really apprehensive about these things. I don’t like the brain chips, I don’t like metaverse, and I don’t like NFTs. I really hate how technology has become integrated into our lives. I don’t like social media or email because I don’t think that it’s healthy for humans to constantly stay plugged in, but it seems like these things have become necessities these days to participate in society.
I get really worried about things like another carrington event or a shortage of resources that are used in computer parts because that would mean the complete and total destruction of humanity due to our over reliance on technology.
Am I just being too paranoid? Are these things actually a be positive? Serious answers only

Normal persons perspective:

Swearing > stern words

Shouting> raised voice

Slapping < punching

Stabbing > beating

Murder > attempted murder

Beating < Murder

Also:

Rape > murder

What's the scientific explanation for the last one?

>Most places would sanction lethal self defense for rape.
But not homicide in retaliation for rape, right? Should keep in mind, there's no reasonable way before the rape for the victim to be sure it's going to be ONLY a rape.

There might be some point to be made here that murder is defined as unlawful killing, while rape is non-consensual sex. The victim's choice has primacy in the latter, while in the former you could look at it as "merely" a transgression against the state's monopoly on violence.

Maybe matter is just curved space with some light trapped inside. Light keeps running in circles and curving space. To maintain the system. When more light enters it, the system becomes unstable and some light escapes.

it is an interference pattern. destructive interference occurs to cause the troughs. Just because the troughs don't go to zero doesn't mean there isn't any destructive interference.

You could try Histology. You'll get a lot of breast tissue and colon samples, but it's a solid field at least. You're going to likely have to have a small staff of some kind, especially if you're not wanting to work under another practice or hospital group. Don't despair. It'll work itself out, you just need to weigh your options out for yourself and keep a good list of pros and cons.

Most of the metal is valuable because we don't have to spend the huge expense to lift it into space. The most valuable of it might be worth bringing back, but e.g. iron is probably worth more in orbit than on the ground.

Completely false. A lot of the rare elements used to make specific types of steels are destroyed in nuclear power plants when they're literally irradiated into different elements.

Then they splatter into tiny molten pieces across several dozen square miles. It's like milking a cow, and then having bottles of milk launched into the ground next to the store at ballistic speed. Do you still have milk at the end of it? More or less. Is it still usable in any way? No.

I have such good feelings from combinatorics.
I'm pretty bad at it, but I'm also maybe the stupidest person who's ever gotten a math degree.

But I just fucking love ""advanced counting"".
There's something about it that feels so good to me. I also think it's undeservedly denigrated to "some subtopic" in "discrete" maths. Or a sidenote in graph theory. Or shit like that. But honestly dudes? I just really like combinatorics. It feels good and great and I like how it makes me feel.

Can people smarter than me talk about combinatorics?

I think I have some alternative explanation for dark energy, but not the education to express it mathematically. Regardless, the basic concept of my idea is this: the deformation of spacetime due to gravity is the driving force behind the expansion of the universe.

Consider the typical analogy of a sheet of elastic material, such as latex. There are two ways of creating a larger surface area on this material, both involve stretching. You can either pull the sheet uniformly in all directions, or apply pressure to one part of the sheet. This behaves in the same way that mass deforms space. The presence of any energy in spacetime creates a deformation which gives rise to the force we know as gravity. This bending of spacetime must create additional space though to account for the curvature, in the same way the surface area of an elastic sheet increases as it's stretched.

This may also have some potential explanation for the strange behavior of gravity in the early stages of the universe, as well as gravity's relative weakness compared to expectation. As the elastic sheet is stretched further it becomes harder to deform - think of a sheet of elastic material pulled taught compared to one hanging loosely. Now consider the idea that gravitational force transfers at the speed of light along with the fact that we're able to peer into the very beginning of the universe with powerful telescopes. This can very easily imply that the driver of the Big Bang and current universal expansion is simply that space is bending as a result of the incredibly dense regions located at the edge of our observable universe. This preserves that space expands uniformly everywhere still as the observable universe is unique at every point in space.

This may be entirely unreadable and a load of shit, regardless I hope it's at least an interesting thought and worth some consideration.

Basically, all universities in continental Europe are underrated by any of the commonly use metrics or university rankings. They all greatly favor the Anglophone world, and the US in particular. There are a lot of really great French and German universities that are super underrated, and ETH is one of them. Ludwig-Maximillian is also really good, and of course the Ecole Normale Superieure and Ecole Polytechnique. And many others too. Eastern Europe has some great schools too, e.g. Etvos Lorand or Moscow State.

Don't look at university rankings or publication counts as you primary means of assessing the value of a school. Look at the names in your subject and where they work or went to school, and which universities host the biggest conferences on your subject.

Weak bait, but I go for it. What you do is believing. You should now, that every data should and can be discussed, because otherwise you will end up with false paradigma and will not longer be able to do bias free research, which is really hard anyway since big money is involved. To say something is true, because the raw data of, in this example a rankink, any form of research is objectiv is like saying that molecules exist, therefore every claim a chemist makes is true.

I had my second semester of real analysis in college was “flipped”. It was part of some initiative to attract more minorities. It turned out being easier because the professor was too nice/pushover, and it wasn’t that bad I still remember most of it years later.

I also had calculus in high school flipped. I loved that too. I never had to do homework or worksheets (all that was optional in my classroom). I didn’t even bother to watch the videos, I just read the textbook. The hardest part was during the AP exam when the red haired nerd was assigned to sit next to me. She was constantly tapping her pencil and fidgeting even after I asked her to stop multiple times. It was so aggravating because she shook our whole shared table. She was also struggling really hard on the exam judging by her bubble sheet and I heard she barely passed it. Fucking hated that bitch she was 3rd in the class and very dramatic, formerly homeschooled, pretended to be poor, and she had a total breakdown when I beat her in the class rank. I never cared about grades but I believe God intervened just for my amusement that day.

This is /sci/, computer /sci/ is still /sci/, I think that the AI will be the biggest hurdle to get over, how close are we to having realistic sexbots? Their physical bodies need to be realistic, appearance touch, orifices, etc. They don't have to be Detroit: Become Human tier, they just need to be realistic for one purpose: make a good fuck buddy. They need to be able to respond to simple commands, make basic conversation, and have the right programming so they don't accidentally injure you. Basically you de-activate them when its not sex time and when it is time they are 100% realistic for that/those tasks and situations only.

We do this and women are irrelevant, you can have any sexbot you want, any human, anthro, animal, either sex, anything you can think of. Imagine smoking a fat bowl taking 2 shots and getting a bj and reverse cowgirl ride from your favorite porn character, and it looks feels and sounds 100% real.
SIMPs dissapear, pussy power dissapears, everything is great.
If you don't care about these things themselves, you should care about the technological advancements in AI that will result from it and also all the money you stand to make from investing into companies that are making this stuff.

It's a combination of engineering issues to me. Look at the current state-of-the-art hardware with ATLAS. It now runs off batteries for a decent length of time, but it still weighs twice as much as it would need to and is way too bulky. With proper funding I'm sure a usable enough "AI" for a sexbot wouldn't be anywhere near as hard as humanoid robotics has been. There would be serious constraints but it would be much more feasible.
