you dont understand electricity at all, huh?

I don't think the pressure affects the electrical conduction at all, or at least very little.

>>9004929
Not much if at all. It would probably take more energy to operate a pump at a greater depth cause the cable would need to be longer

B-but /pol/ told me it'd work!!

I know some "progressive" New York Architects are thinking of creating a sky scraper that attaches its top to a satellite in our orbit, and touches down on the ground. At least they made the windows be made of different materials and shapes to accommodate atmospheric pressure at different levels

Both are absolutely known and proclaimed ad nauseum not to describe base reality. Both, however, accurately model our observations at their respective levels with a great deal of precision.

Also, you're a retard.

What's your reasoning?

>>9007727
what's the question though?
fill the striped spot?

>>9007609
It isn't stagnating, the market is. We're in a period where the advancement of our technology is too similar to what is already there to be feasible for consumer production. So we keep advancing for workplace/research purposes but won't make another major consumer shift until we hit a breakthrough.

If you want to be /pol/ you can argue that welfare politics means our productive population is being replaced with less intelligent and innovative people by the far left I guess.

>>9007625
I see what you're saying. Market forces are holding us back.

>If you want to be /pol/

Ugh. No thank you!

>>9007609
>Is a technological singularity possible?
No. Technology is reaching its limit. Once transistors get as small and efficient as they can get it's over. In the future you can expect higher resolutions and faster cpus and gpus, but nothing else.

>>9007625
Keep coping. Even if we weren't limited by the market all our new technology since 2007 has been dull or basically useless. In fact anything new that had actual use inherently WOULD be feasible for consumers.

>>9007223
OP is psychologically addicted to sucking dick

>>9007223
I don't know much besides that people with it rely on whatever thing their addicted to as a a copping mechanism. Or something like that. Though I'm most likely wrong.

>>9007229
copping mechanism?

define "phenomena" and "in the universe"

>>9006809
More or less. As we start moving towards more realistic and complex systems we have to give up certainty, but I don't think that's too much of a problem.

The measurement problem refutes materialism.

In the standard Copengagen interpretation of quantum mechanics there exists a ‘Heisenberg cut’ – a boundary between the observer and the observed. Von Neumann argued that all material objects must be placed on the ‘observed’ side of the Heisenberg cut, and that only consciousness can be placed on the ‘observer’ side.

This is because if we start with a superposition (S), the interaction of S with a measurement apparatus (M) would result in a superposition. But we could think of another apparatus (M0 ) that measures M and S, and we’d still have a superposition, and keeping doing this indefinitely, ever adding more measurement apparatuses to the chain – including our eyes, our optical nerves and our brain. We would be left with a brain/measurement apparatus/system that is still in a superposition. But since we never actually observe a superposition, this chain needs to stop somewhere. According to von Neumann there is only one step when we know for sure that we do not have a superposition: when we gain conscious knowledge of the measurement apparatus; i.e. when matter interacts with the mind.

There are four assumptions here:

>State completeness
Assumption 1 can be thought of as the assumption that there are no hidden variables unaccounted for in the standard quantum state – in other words: Bohmian mechanics. However, Bohmian mechanics is plagued by problems. One insurmountable one is: Hardy's paradox, any local realist theory predicts the probability of a certain combined outcome to be P=0, while experiments and quantum mechanics say P=1/16. There is no calculation in Bohmian mechanics that reproduces P=1/16. Thus, the theory is incompatible with the experimental facts of modern physics.

>No collapse
This is the assumption that the linear dynamics provides a complete and accurate description of the evolution of the physical state for all systems at all times. But theories of this nature (like GRW) must be rejected on the basis that there is strong empirical support for the linear dynamics insofar it has always made the right empirical predictions whenever we have been able to isolate and control a physical system well enough to test it.

>Empirical consistency
There is no reason to reject this.

>no branching
This assumes the measurement interaction between an observer and a physical system typically yields a single determinate measurement result. In other words, if this is false the Many Worlds hypothesis may be true. But no Everettian has been able to derive Born probabilities. This renders it useless as a scientific theory.

Thus, we are forced to accept that Copenhagen is correct and that the Heisenberg cut is one of the main axioms underlying quantum mechanics. Defining an observer as an immaterial mind is difficult to accept for someone wedded to materialism; but it is the only way to solve the problem of ‘where to put the cut’, while holding to the Copenhagen interpretation.

We are therefore forced to reject materialism and accept either mind-body dualism or Berkeleyan idealism.

Thanks for the prompt and thorough write up. Lots of terms to punch into Wikipedia and YouTube.

Cheers

How autistic do you need to be to spend time on doing calculations on shit like this?

Humans won't live to see the end of the universe. Whether that be because of an extinction level event, or we just evolve into something different, humans wont be around billions of years from now.

Science is a tool. It doesn't have a purpose in itself.

A hammer has a purpose.

ashkenazi jews have the highest IQ of any ethnic group. Also, their group consists almost exclusively of high IQ members, bringing their average higher.

>>9006024
They're extremely well connected, so they get access to the best tutors, preparatory schools, and universities.

He's trying to figure out what "We have spectrally resolved the intraband transient absorption of photogenerated excitons to quantify the exciton population dynamics in colloidal PbSe quantum dots (QDs). These measurements demonstrate that the spectral distribution, as well as the amplitude, of the transient spectrum depends on the number of excitons excited in a QD. To accurately quantify the average number of excitons per QD, the transient spectrum must be spectrally integrated. With spectral integration, we observe efficient multiple exciton generation in colloidal PbSe QDs.

Damn researchers aren't doing science for us drug users.

Clinical trial of flouxitine and lsd when

I'm not a doctor or a pharmacist. But I have a feeling that the LSD would cure your depression as the flouxitine would just suppress it.

>>9005745

Do NOT take lsd with anti-depressants, not only is it dangerous, the anti-depressants will neutralize the effects of the lsd. If you are on any kind of anti-depressant, stop taking them for a day or so before you take lsd.

On the other hand this doesn't mean we can solve all problem if I have correctly understood what Goedel means.

Then you didn't understood anything about Godel

That's not what the Incompleteness Theorems say.
