Sums up what I do pretty well.

However, I also do study groups once a month for my upper-div courses and then study hard for finals week. Maintaining a 4.0 in my undergrad. Definitely an over-achiever and half-brainlet.

"AI" is codeword for "I'm stuck in the 1920's". Only DL and RL are worth studying nowadays. Shitloads of SJWs everywhere, though, not sure if it'll still be science by next decade.

Hey /sci/.
So I'm taking a basic (baby's first) biology class in the springtime. I need it for my community college AA (transfer degree).
I'm getting my feet wet in all kinds of subjects and can't really pick a major. I'm very optimistic about biology.
I'm just worried it won't be a very engaging class.

Are there things in computing or programming that just work and we don't know how they do yet? Like any mysteries or something that can't be figured out?

I can't imagine there possibly could be, since we made all that stuff from scratch, but I won't know unless I ask I guess.

Ya a lot of stuff is just guess work. Best example I can think of is in real time applications. You really don't know what's going on at any point with the data but just have statistics to go off. There's noise in computing that we can't explain or predict completely. We just know how to get around it and such at the expense of efficiency.

What you are describing is in fact actually happening now, with some regularity.

It goes like this: computer programmers program a computer or series of computers to do a bunch of different, very complicated and tedious/onerous things. Prove a theorem, trade on the market, etc. But a complex and rich behavior emerges.

Then the computers do something that is either a pleasant surprise, or unexpected. They cause the market to start crashing, they prove the theorem, or they accurately model the physical phenomena, and reproducibly so when the computer program is run again.

/And in each case, the programmers themselves cannot understand in specific detail exactly how or why it it is that the computers managed to do just exactly what they did/. Or, /the programmers themselves can't understand how it is that the computer is right/. But right it is.

This goes directly to your completely reasonable suspicion: humans programmed the thing, of /course/ they should be able to predict or explain its behavior! In principle, I would initially expect the same thing: you ought to be able to reverse-engineer the whole thing, given enough time. But I've heard quite the opposite enough times now to know (because I've been told enough times at least) that it's a real thing, an emergent property of computers. They are turning into "Black Boxes", for all practical purposes.

I am not a CS person and I tried to look up some concrete links on this, but I regret that I could not find any. I know that someone else on /sci/ knows what I'm referring to though, and can buttress the claims in this post.

What's the verdict on this one? I like listening to some techno and vaporwave(instrumental) when I study, it seems to allow my brain to "chew" on something which some how allows me to concentrate better.

"At Princeton he received complaints for regularly playing extremely loud German march music on his gramophone, which distracted those in neighbouring offices, including Albert Einstein, from their work.[53] Von Neumann did some of his best work in noisy, chaotic environments, and once admonished his wife for preparing a quiet study for him to work in. He never used it, preferring the couple's living room with its television playing loudly."

My answer? I'd say, WOW, reminds me of something I discovered recently related to evolution: The main story people want us to believe is that 4-6 million years ago, humans didn't exist, and that we had a common ancestor with a chimpanzee. They say that this "wan't a chimp" but that it also "wasn't a human." So that means it would have to have features of both. The problem is, chimpanzees don't have features of both, and humans don't have features of both. If humans and chimps don't have features of both, then how could the common ancestor have features of both? That means either humans evoluved from chimps, or chimps evolved from humans. Obviously since humans are more advanced than chimps, the humans must have "evolved" from chimps. However, if chimps evolted into humans, then how are there still chimps? According to evolution, birds evolved from dinosaurs, therefore there are no dinosaurs left. If humans evolved from chimps, then IT MAKES NOT SENSE FOR THERE TO BE ANY CHIMPS

Which of these accidents was worse?

It is my understanding that the Chernobyl core melted out of the containment vessel whereas the Fukushima cores did not, is this right?

Why did the Russians manage to fuck it up on there end so badly? Were building standards really that primitive compared to what we have today?

Chernobyl was worse. The type of reactor in Chernobyl doesn't really have a containment vessel, so when it blew up the reactor core was out in the open. The graphite in the reactor caught fire and the smoke transported radioactive material high into the atmosphere, allowing it to spread over a wide area.

I don't know as much about Fukushima, but AFAIK the reactors shut down after the earthquake, but the cooling system was destroyed. That means that a lot of hydrogen gas is generated in the still hot reactor, and they had to vent it out in order to avoid an explosion. This radioactive steam contaminated the area around it, but didn't spread very far and there was less radioactive material released overall.

Chernobyl was by far worse but this is also true.

Give it 30 years and ask again I guess.

Well let's see:

$10k=$10k

See this OP?? it's the same fucking thing, money is money it doesn't matter how you earn it weather it's through math or sucking your boss's dick it will still have the same value because IT DOES NOT FUCKING MATTER.

Now stop crying about how you don't have a vagina just so you can get money from instagram and start accepting reality as it is faggot.

Picture is of a giant strip mine where they try to locate isolated pockets of ore containing only 1000 ppm uranium. They have to destroy the environment worse than coal mines to extract the fuel.

That mining equipment runs on oil and to transport and refine the ore is also completely oil dependent and extremely fossil fuel intensive.

The byproduct producing nuclear energy is one of the most toxic substances humans have ever created and there is no way to safely dispose of the waste.

How the hell does anyone think this is in any way a good solution?

It's scientific - jobs
It's not very efficient - more jobs
Requires a lot of research to (possibly) be able to clean up the waste - guess

Would there be another +50% spent if all shops were open 24 hours a day?

Is inflation just a cover for ever-increasing inefficiency?
Why should money earnt earlier (when things were presumably less efficient) devalue?
