Why was J.J. Thomson's model of the atom wrong, /sci/?
19 posts and 2 images submitted.
>>
because experiment shows that almost all the mass of the atom is in a tiny positively charged volume at the centre of the atom, and that the large majority of the volume is actually just empty space. The borders of the atom keep negative change keeping the overall system neutrally charged (unless the atom is becomes an ion)
>>
>>7988739
Because the electrons aren't stuck to a blob of positive charge.
>>
It predicts a single emission frequency for hydrogen (and everything else I think).
This is contradicted by experiment.

Words cannot describe how shitty it is. Also unless you're publishing something ground breaking, like you actually understand what causes gravity, nobody is going to thoroughly scrutinize your work. This is why science sucks dick.

So, let's settle this once and for all:

Are viruses living or non-living organisms? My Biology textbook hasn't a clue.

>>7989293
That's actually extremely difficult to say. They are the midpoint between things like proteins and things like bacteria.
>>
>>7989293
They're an elegant demonstration of how biochemical systems can develop the ability to self-perpetuate despite not being particularly complex. The sort of systems that evetually developed into more complex life.

But no, conventionally their inability to reproduce with their own machinery denies them that label.
>>
>>7989293
They're typically considered non living because they don't reproduce in their own and they don't have a metabolism.

/sci/, is it really that hard to remove the salt from salt water?
53 posts and 7 images submitted.
>>
>>7986895
As far as I understand it's not so much a problem of how to do it, it's that boiling/ filtering the water is so energy intensive that it costs a fuck load of money to do so.
>>
>>7986895
Not hard, just expensive
>>
>>7986895
Yes. Phase changes are very energy intensive, presuming you want to boil it out. I don't know about the energy or infrastructure costs of other filtering methods. Something using osmosis probably works better.

Does our inability to decide (by any meaningful procedure) which state an electron emits in prove that the nature is essentially non-computable?

Also what is the actual trick with the Stern-Gerlach experiment?

I mean, can you prepare a system such that it won't be possible to measure spin or down regardless of how precise your measuring device is?
>>
>>7975673
>system such that it won't be possible to measure spin or down r
yes. take a spin up in the z direction, put it into a stern-gerlach measuring the x-direction, now, in whatever branch out of the apparatus, you know nothing now about the spin in the z-direction.
>>
>>7975701
Erm, that's not quite what I meant. Also, I don't know QM that well, is it a kinda of what's described in the OP-pic?

Anyone think that /sci/ is full of SpaceX shills? I remember not long ago when they were trying out their rocket landings most of /sci/ was dismissive of Musk as they are to everything in general, yet now you can't say a bad word against the guy without 10 other posters attacking you. NASA is routinely trashed, the Russians, Chinese and Japanese are barely ever mentioned, this place is just "SPACEX SPACEX SPACEX!"

You have a ten-year odyssey to embark on,my friend.

You will scream in agony as the frobenoids tear through the p-adric confines of your as yet Euclidean asshole, and feel the fabric of all possible systems of math expanding in a network of interlocking value systems and alien topologies, but if you ride upon the crest of the infinite wave of Teichmuller possibilities and remain,in some sense, whole, then you too will look upon the clam, beaming face of the End of Math, and feel the geodesic tears of enlightenment fall and expand into swirling universes of mutating, interlocking mathematical dances.

>Durably reducing transphobia: A field experiment on door-to-door canvassing
http://science.sciencemag.org/content/352/6282/220.full
https://archive.is/7GAoL

>Abstract:


Existing research depicts intergroup prejudices as deeply ingrained, requiring intense intervention to lastingly reduce.

Here, we show that a single approximately 10-minute conversation encouraging actively taking the perspective of others can markedly reduce prejudice for at least 3 months.

We illustrate this potential with a door-to-door canvassing intervention in South Florida targeting antitransgender prejudice.

Despite declines in homophobia, transphobia remains pervasive.

For the intervention, 56 canvassers went door to door encouraging active perspective-taking with 501 voters at voters’ doorsteps.

A randomized trial found that these conversations substantially reduced transphobia, with decreases greater than Americans’ average decrease in homophobia from 1998 to 2012.

These effects persisted for 3 months, and both transgender and nontransgender canvassers were effective.

The intervention also increased support for a nondiscrimination law, even after exposing voters to counterarguments.

and what about a 10 minute talk exposing the problems, the suicide rates, the fact telling them their delusions are real doesn't "fix" anything, and the fact they want to brainwash children into their marxist cults
>>
They should be spending more time on figuring out the reasons for transsexualism, instead of this nonsense.
