Anyone into theoretical linguistics? What do you think about age-old debates like cognitive vs generative grammar?

Opinions on pic related? Fuck his 9/11 tinfoil hat theories, what about universal grammar?

Do you think that people are born with the innate capacity for language?

Does anyone even giving half a shit about topics like this?

>Do you think that people are born with the innate capacity for language?


It's really hard to argue against it in view of certain evidence

http://www.nature.com/neuro/journal/v6/n7/full/nn1077.html


To the great majority of theoretical linguists, this debate is still a few years away in terms of relevance. The truth is we don't really understand the relationship between language and the brain well enough.

do philosophers have anything to show for besides black and white pictures of them looking pensive? i don't think their work age very well given that philosophers live long enough to see their work become irrelevant.

The meme is that as they are working at a job that has nothing to do with their degree they should have just been able to get that job out of highschool.

They cant though because the military-industrial-academia complex is trying to scam everyone out of their money.

Alright /sci/ I come to you as the only possible hope, however remote, of laying out the goddamn facts on solar.

Is it a meme?

>pollution from production and batteries
Does this actually outweigh power from coal or natural gas right now?

>but the sun is free!
Battery lifetime and solar panel lifetime has to be accounted for. I've seen power output datasheets that indicate solar setups lose something like 50% of their net output over ten years. This tells me the expected lifetime of a solar installation is likely to be 25 years, then you have to pollute more to get more batteries and dispose of your old ones (how?) and possibly newer panels, too.

Can someone just give me some no-bullshit analysis? If you don't know sources, google is of no use because all you get are hippie websites and manufacturer advertisements. I've been attempting to research this for about a week and it's getting me pissed that the whole solar industry appears to be a meme.

No, but it's never going to be a grid level solution. I think it's reasonable to have them for personal use, but that's only because you should have some actual infrastructure as a fall back on.

I don't want kids, but I do want my legacy to live on. On my death bed, I'd like to launch hundreds if not thousands of vials of my semen into space, in the hopes that they seed life on the habitable planets I direct them towards (assuming affordable and reliable launch technologies have been produced by then).

Would it be at all feasible for life to evolve from my frozen sperm, assuming it landed on a habitable planet?

I like the idea that in four billion years there could be an intelligent civilisation built from my semen.

Your gametes themselves will never seed life. They exist only to join with the female gametes, the ovum.

I think in order to make this work, you will have to let the semen go a bit fetid, to ensure that bacteria is mixed through the sperm cells. These bacteria then may go on the seed life, with your semen as food.

This however, will still fail, as all life must be seeded from phytobacteria which gains energy from the sun. The bacteria in your semen will not be of this kind, and will quickly die once the semen nourishing them runs out.

In short, no, this plan is not feasible.

I am trying to design a habitat for fish in microgravity and want to know whether my design is feasible.
Currently, fish are just being held in stationary tanks and have no resistance so their bones become less dense and if they were brought back to earth would likely die.
I made what is essentially a centrifuge for them which I think would create artificial gravity if spun if I am not mistaken.

I get that it's considered pseudoscience in the psychic term, but wouldn't one be able to 100% predict everything that'll happen in the future with sufficient data on the present?

Also is there any scientific argument FOR free will, or does it only persist as a theory due to lack of understanding? The same question goes for determinism. I don't remember hearing if quantum mechanics supported or went against determinism.

I don't know. I can't find any statement that it completely is. When I look it up I just find that it's either debated or might be once we learn more, but might not be as well.

Or something like it is macroscopically which means it must be on a quantum scale too?
>>
>>8943390
To predict the events of the universe with 100% certainty, you'd need to simulate a universe. The smallest possible simulation of a given object is that object (simulating a quark in reality uses more that a single molecule, but let's give benefit of the doubt and say you can break physics).

Are our brains quantum computers?

A couple weeks ago when I was studying for final I was doing some equations, but at the same time I was also thinking about something else (mentally reminding myself about another subject; chemistry). I was able to process two different things at the same time without realizing it. I hope I don't sound like a brainlet.

No, but they are built on heavy parallelism, aka neural networks.
At higher level thoughts appear mostly sequential, but parallelism is what the brain is really made of.
