Why do people assume that a robot uprising is even possible?
Is there any reason to believe that a programmed computer is capable of reasoning beyond its programming?
>>7846851
>reasoning beyond its programming
you done fucked up
the reason every scenario starts this way, is because dumbfag engineers like you assume that your overlord math and physics doctors have foreseen and tested every possible interaction the programming can handle
>>7846851
Robots do what they are programmed to do. The fear should be that all human programmers are fallible and some human programmers are malicious.
>>7846865
This. The threat is one of robot programmers messing up and writing rules with unintended consequences. Which if you are not a programmer may not sound very realistic but I can assure you it's a very real possibility.
What's the point of water fluoridation?
It doesn't really seem to do anything beneficial. Might even be responsible for some adverse effects that no one really bothers to investigate further in fear of getting attacked by big name fluoridationists.
Yet CDC et al seem to be obsessed with it over sketchy, weak, and contradicting data.

From what I gather it was a good way to dispose of toxic waste from the Aluminum manufacturing industry that grew to epic proportions in the US.
Instead of paying to dispose of it, they paid off some dentists to shill the propaganda that is was good for teeth, then could sell it to water plant operators thus diluting it slowly to non toxic levels through water treatment systems. Medicating drinking water is suspicious and could all be tinfoil literally, however it for sure causes pitting in teeth and calcification of the third eye, the pineal gland. Apparently the Nazis used it to pacify their death camp subjects.

Reducing dental decay. But you already knew that.

Poe's Law post
Consciousness does not exist. It is a modern version of an outdated concept: the soul. There is no correlate of consciousness in the physical world. We hold on to the concept because we still believe that there is some, "us" that exists independently of our physical bodies. When I say that consciousness does not exist, I am not talking about awareness, or perception, or experience itself. I am talking about the idea that our brain, "produces" something. And that that something is different then our bodies themselves.
In reality, there is only the body. The mind is tangential to that. Transhumanists and others believe that we eventually will be able to remove our consciousness from our bodies. I think this is nonsense. The process is a property of the medium, it can not be divorced. If I recreate the exact state of my digestive system in another person, it does not make it my digestion. The "our-ness" of our brains is more then the exact synaptic states of all the neurons, it is the neurons themselves.
Neuroscientists and philosophers have searched a long time for consciousness, to no avail. The obvious answer is that it doesn't even exist. And why should it? Just because we imagine something doesn't mean it exists. In fact, I think the concept of soul/consciousness is so deeply ingrained in our understanding of the world it is difficult to see past.

Well, suppose you replaced a cell in your body with a device that ran a digital simulation of the cell and had a biochemical interface to interact with the rest of the body. Next, you repeat that process one by one for all the cells in your body. Then, you wirelessly connect all these devices to a single computer across the room and move all the simulations there.
What do you think happens with respect to consciousness and experience?
As a transhumanist this is the kind of approach I might want to use to remove my consciousness from my body. It seems plausible that the person involved wouldn't notice any step of this. If you also simulated all the other noncellular stuff in the body and had a way of converting digital video and audio and such into simulated biochemistry, you could connect the computer simulation to a virtual or robot body and turn off all the devices in the physical body and they could happily live on in said artificial body.

What is the clue to solve delta-epsilon proofs?
Pick any epsilon, find delta

Get gud with inequalities

Inequalities by Hardy, Littlewood, and Polya
>>7846590
Do you have an example that you'd like to work through?
General methodology:
- Work backwards, start with the inequality bounded by epsilon that you want to obtain and try to work back towards being bounded by delta, then choose that delta.
- Leave gaps in your work and jump to what you would like to achieve. Sometimes the delta to pick becomes obvious that way.

How do you science the shit out of this? Failure is not an option.

You have to give more descriptions, bro. Is there a spacecraft nearby? Some way out? If not, it's just impossible to get out of the planet, of course. The land isn't fertile either so anybody in that situation would be screwed and would have to just wait for death.

Kek. You must be an engineer.
I stopped caring about math when I was introduced to the concept of imaginary numbers. What a crock of shit. If your equation can only be solved by inventing numbers that can't exist, like some kind of math deity , then you are fucking wrong and the math is flawed. Same for algebra solutions that basically say "the correct answer is whatever the correct answer is". Thats what the math said transcribed to words but god forbid if i wrote in down in english instead of the ancient math runes the teacher word mark me wrong.
Math is logical and numbers never lie my ass. Math is just as flawed as any other human construct.
>>7846556
Here's your (You)
>>7846556
I realized imaginary numbers were real when working on precession. a 2D number plane is the only way to explain it. You see precession is all about addition of angular momentum causing a rotation. How can you add something to get a rotation on a 1 dimensional number line? There must be a second dimension orthogonal to it that it goes through in order to end up rotated.
>>7846556
Oh man, I guess Electrical Engineering is bullshit then, wonder how all those electronics ended up working when designed if imaginary numbers are a crock.
>field with one element
>mathematicians investigate it
>>7846555
there is no field with one element, you mong

>assuming fields must have 1!=0
might as well assume that all conjectures are true.
It's not interesting because there are no ring maps out of it and the zero map is the only map into it from any other ring.
Any Americans here ?
I'd like to know what do you learn in highschool in mathematics and physics. I searched on the internet but there were no clear results.
I'm in 12th grade right now. Intending to major in Physics.
In science I'm in AP physics C ( E&M and Mech) It's pretty fun actually.
In math I'm at the equivalent of Calc I or Calc AB.
Most people do Physics C and Calc BC together - which is Calc II in the US.
>>7846571
What do you learn in Calcul I and II ? I would like to compare it with what I learned in France (I was in the equivalent of the 12th grade last year).
>>7846571
As a non American, what does any of this mean?

What makes something nuclear?
When neutrons are so packed it takes a small amount of energy to make the atom release them into other atoms and so on until you have a chain reaction which creates anime.
you mean "radioactive". Radioactive material is something that has unstable isotopes. This means it's made of atoms which undergo fission (with some probability). Since fission releases energy and neutrons, it's dangerous to be close to a radioactive material. They are easy to spot though since they give out heat so they tend to glow and are warm to the touch.

The theory of quantum tunnelling derives mathematically the result that particles have a non-zero probability of passing through a barrier which in classical mechanics would be impassable. It predicts that particles can pass through walls.
Now a ball is clearly made out of particles. Therefore there has to be a non-zero probability that a ball can transition through a solid wall.
Why has this never been observed?
There have been hundreds of thousands of recorded sports matches with balls, but not even once did we see a ball transition through a wall. Not even when it was kicked with full force against the wall, i.e. should have more energy and thus a higher probability of passing through the wall.
Explain pls.

Why do people believe superintelligent AI could solve all our problems and rule the world and do all other sort of magic stuff?
>>7846260
>people keep posting an image of a book they probably didn't even read themselves
Well excluding the magical stuff, a lot of our problems as a society can be solved be a smarter problem solving, state budgets for example, there are many factors, some of them are interwined some are not, over all this is a kind of task AI's are good at, AI doesn't have to be perfect, and by AI I don't mean the conscious bullshit, it's simply a program that preforms a task that wan't explicitly programmed and improves somewhat with experience, AI can be exremely helpful in the future, but it's not the second coming of jesus.
