Not sure if that is the right place, but can't find any better fitting board.

What are the main problems when it comes to finding missing people? And what could be improved, especially when it comes to people who are already missing?

What I meant was, we could create a database with pictures of everyone and use that with CCTV or other stuff in the future, but it wouldn't help with cases of people who are already missing, especially if they went missing years ago.

I'm doing a computer science degree and was wondering if I could find something to write my thesis on that would actually help investigators
I think one of the biggest problem is people eventually give up looking. If you got to wikipedia you can see a lish of missing people from the early 20th century to the present. Most of these people have now been legally declared dead. In that case nobody is really looking and even if they are chances are slim. A good example of this is Tara Calico.
Ha, just look harder. They're always in the last place you check haha.
A main problem is that in some places, there is a certain amount of time has to pass before an adult can be reported missing. Unfortunately, the later you start looking, the lower chances you have of finding the person. All this could be fixed if everyone was forced to have government tracking chips installed in their bodies.
we have neural nets that project facial development from past photos and relatives, sometimes they're fairly accurate.

soon, I'll be graduated from high school and i will be able to choose my future job/project, so i have alot of things in my mind, i firstly wanted to go to medicine college since it gives me a very well paying in the future and a good addition to my persona, at least where i live.
then, i have heard people talking about nuclear engineering and i got into it, how i will be switching between cities and nations, how i will be studying a really hard and complicated subjects, and most importantly, how i will be internationally important.
so, anyone here studies nuclear engineering or at least has a friend/relative who does that can inform me about it?

It doesn’t matter what major, a bacharel will not make you special, 0 chance.

Are you Russian? I think RosAtom is in charge of 70% of Nuclear plant construction around the world and it's owned by the Russian gov.

If not, there is a shortage of Nuclear engineers but Nuclear energy is not doing to well these days

If you're at a top-tier research institution, you'll often hear that there are privately funded research that are sometimes decades ahead of the mainstream, be it in the medical sciences, computing or some other fields.
Just this week I came across two papers on unsupervised learning written 20 years ago that resembled some "novel" techniques developed by Microsoft Research in 2019.
Have you ever come across "secret/unpublished research" of note, anecdotal or otherwise?

Are there any semi-plausible natural phenomena that would fuck with electronics or electrical fields in a small area, better if internment.
Bomb the nearest transformer and claim it was a meteorite, alternatively run fifty microwaves with the doors removed and claim sun spots
Bursting stones.
It is conjectured that the fields created by large bursting stones were responsible for people reporting alien sightings, as they are strong enough to influence brain activity.

Humanity continues to face two simultaneous existential dangers—nuclear war and climate change—that are compounded by a threat multiplier, cyber-enabled information warfare, that undercuts society’s ability to respond. The international security situation is dire, not just because these threats exist, but because world leaders have allowed the international political infrastructure for managing them to erode.


The Bulletin believes that human beings can manage the dangers posed by the technology that humans create. Indeed, in the 1990s leaders in the United States and the Soviet Union took bold actions that made nuclear war markedly less likely—and as a result the Bulletin moved the minute hand of the Doomsday Clock the farthest it has been from midnight.

But given the inaction—and in too many cases counterproductive actions—of international leaders, the members of the Science and Security Board are compelled to declare a state of emergency that requires the immediate, focused, and unrelenting attention of the entire world. It is 100 seconds to midnight. The Clock continues to tick. Immediate action is required.

However the classic way to derive the formula for a circle's area is by taking a limit on a series of regular polygons. So what do you need to use this kind of stuff?

Over the past few days, I have been studying Gauss' life and became surprised on that he admired Newton to such a great extent.

In his youth, he ardently read the works of Euler, Lagrange and ofcourse Newton but one man strangely caught his interest above all, and that was none other than the Englishman.

Gauss himself once claimed that he read Euler for the rich substance but Newton for the rigor and "style". And indeed, Newton had a well-reputed (or ill-reputed) "synthetic" style through which he obscured and erased completely anything that might have given the reader an idea on how he reached the proof. (His Principia was criticized by his contemporaries on this point).

So thus it is very clear where Gauss got his tendency to be, in Abel's own words, "like the fox, who effaces his tracks in the sand".

Gauss even mastered English so that he could gain further insight onto the life of Newton, and his library in later years became replete with English literature.

And not only that, he even applied the Latin adjective "summus" (which means greatest) to nobody but Newton, and even once said that "Newton was the master of all masters!".

the problem is that its hard to believe.... I don't think an 18th century German mathematician like Gauss would of known who a English 17th century physicist like Newton... the vast distances, Newton was only known in England etc
is this true?
I don't think so.
>Until the middle of the 17th century, mathematicians worked alone or in small groups, publishing their work in books or communicating with other researchers by letter. At a time when people were often slow to publish, “invisible colleges,” networks of scientists who corresponded privately, played an important role in coordinating and stimulating mathematical research. Marin Mersenne in Paris acted as a clearinghouse for new results, informing his many correspondents—including Pierre de Fermat, Descartes, Blaise Pascal, Gilles Personne de Roberval, and Galileo—of challenge problems and novel solutions. Later in the century John Collins, librarian of London’s Royal Society, performed a similar function among British mathematicians. In 1660 the Royal Society of London was founded, to be followed in 1666 by the French Academy of Sciences, in 1700 by the Berlin Academy, and in 1724 by the St. Petersburg Academy. The official publications sponsored by the academies, as well as independent journals such as the Acta Eruditorum (founded in 1682), made possible the open and prompt communication of research findings. Although universities in the 17th century provided some support for mathematics, they became increasingly ineffective as state-supported academies assumed direction of advanced research.
Gaus was 23 in 1800 btw. He was more early 19th century than 18th.
>why was gauss obsessed with Newton?
Even the most intelligent men are fascinated by the allure of a virgin.

The common argument against sexdolls from most people is that it allows men to never "man up" and "talk to women". What do they mean by this? Talking to women makes them want to fuck you? Why is the human mating ritual so difficult that some men choose dolls without attempting to interact with women?

>No. In other words, you'll never find out if you don't try

LMAO COPE! If you have to try, it's over. If you would look like Brad Pitt, women would approach YOU on the DAILY! CHAD has no idea what approaching and game and all that coping shit even is, Chad never talks to women because THEY offer HIM sex on the daily.
I mean those dudes who dont "man up" (lol boomer language) and talk to women will never do it anyway. They probably wont even make many friends. Long story short, having sex robots will allow these men to continue to view women as sexual objects who's only use is sex and telling them how amazing they are at everything, at worse. It will cause websites like this and /r/ nice guys to lose virtually all traffic at best. Who really cares at the end of the day?

what is the difference between fractals and recursion?
you can recur, but you can't fract
recursion is more fundamental and is required to generate fractals
fractals are objects, recursion is procedural
