/sci/ - Science & Math

>>8847879
see this is the fucking problem, you'renothelping.jpg

just get tyson and nye on TV more. i know /sci/ hates them but they promote basic science literacy and basic critical thinking and even a little bit helps a lot.

>>8847748
See, you just politicized it again
If you want to fight on policy, go for it, more power to you
but if you want to push policy and science in general at the same time, please don't

Congrats, march for science, you managed to further politicize objective reasoning and experimentation and only further alienate various "skeptics". They can now point at shit like
>>8840684
and claim global warming is a hoax made up by trannies or whatever.

this march is the definition of "YOU'RE NOT HELPING"

fuck! i missed it

>Uranium and graphite occur naturally and are not dangerous
true, but the stuff released from chernobyl was the real dirty stuff, mixed with all kinds of nasties from normal reactor operation, and it got pulverized and spewed all over the place, AND THEN all the encasing graphite (impregnated with nasties) started burning and kept burning for a long ass time, spreading all over the place. and stuff dont go away quickly

chernobyl was very bad
fukushima was kind of worrisome for about 36 hours, then it was mostly just alarmism

>>6364275
>If you think there's a "vast" difference between Chernobyl and Fukushima other than Fukushima being located on a coast and luckily having nearly all of its radioactive material blown out to sea, you're badly ignorant of one or both.

welp that's all i needed to hear
i have a homework exercise for you, go look up the amount of uranium and burnt graphite released from chernobyl
then look up the amount of isotopes released from fukushima
just total volumes

and decommissioning isnt THAT bad, and waste disposal also isnt that bad. nuclear reactors generate so much revenue, stably, over their entire extremely long life that its usually more than worth it.....or at least it would be if there were no political insanity surrounding it, and if yucca mountain was a thing
what sucks is decommissioning after an accident, mostly because everything is really messy instead of just the pot and the piping

>>6364204
>or to try and hide how bad it is by running reactors past the end of their planned service life
also, this is mostly because nuclear power plants are legally quite difficult to build in the US (all dem lawsuits), but the demand for their electricity is still there
and they make a LOT of electricity
so the current practice is to use existing plants and retrofit them as needed, and it seems to be doing ok, but i'd prefer new plants

>>6364204
>Fukushima was evidence that "modern" nuclear power plants in first-world countries could blow up and spray radioactive materials as badly as Chernobyl did.

ok, either you're vastly overestimating fukushima or vastly underestimating chernobyl
which is it?

>that greenpeace commercial
>airplane hits reactor dome
>implied horrible accident
uh
that jet would be smeared across the dome. SMEARED. those things are terrifyingly strong

>>6363678
dis
the concern has been and always will be a steam explosion basically atomizing the fuel rods and spreading them all over.
except i dont really think that can actually happen in "modern" reactors
chernobyl was a russian reactor, meaning it might as well have been built in 1890

>tfw imagining how EARSPLITTINGLY LOUD this thing will probably sound during operation
i think it needs to fire like 5 times a second, continuously. imagine the din that would make

....what recent experiment in california

http://www.generalfusion.com/slides/#gallery2
>mfw they updated the general fusion website finally
>mfw it actually looks pretty good, nice CSS usage

>mfw it has one of the best quick primers to fusion power out there, even if it mostly just craps on MCF and ICF in favor of its own

anyone else excite?
when are they going to do test firings?

oh no, they did fine. daiichi was a fuckup in the sense that the tsunami was utterly unprecedented and they left the generators in the basement, as well as a slightly cracked reactor pot.
the rest of japan's plants shut down without so much as a cough

basically it's a reminder to think ahead more based on geography. china's quick-build reactors have a giant reservoir above the core that can drip-feed water by way of gravity during an emergency, and it'll keep dripping for three days straight, pretty clever shit.

best we got right now is the alcubierre drive
and recently there's been some strong evidence that it won't be quite as difficult as we first thought
but we still need negative mass, which as far as we know isnt a thing

>have managed to coax photons into binding together to form molecules
i...
i dont..
what the fuck?

ok, i can't do it, there's just so much nonsense about christ grids and fighting with greys, and some bitch from peru ascending through the 4th dimension? it's like a bad novel plot.
there's literally nothing said that's verifiable except that there were apparently 500 ufo sightings between 1980 and 1989, which has no source and google doesn't give any specific numbers on ufo sighting statistics

i like to play a game with spirit science
pick a random moment in any one of his videos, watch about ten seconds if you can stand it, and find a source or two completely debunking his inane bullshit

i'll do that right now actually

its a thing but there are pretty massive efficiency hits when you do it, like 50 or 60% over a few feet of range

>>5974831
yes
51 is a cool place with an interesting history
which has nothing to do with ufos

>>5973914
>and that's also why you need to shut your whore mouth. In hindsight it's all too easy to say "oh well I knew it all along"
you fucking idiot
there's been books about area 51's black ops aeronautical engineering shit for decades. you just went straight for the ufo shit
>I think they deserve a little more respect now than /sci/ usually gives them.
if they legitimately call themselves "UFOlogists", they dont.

>>5973882
>Now it's been spelt out I think /sci/ needs to apologize to UFOlogists.
w-what? you're a fucking idiot
nobody denied the existence of area 51 you cock
everyone knew it existed and knew it was used for top secret aerospace stuff

people in the real world knew it was being used for the real black-ops engineering shit, the most recent projects being stuff like Aurora
people in dumb-shit fantasy land "knew" they were dissecting aliens or whatever the fuck

>>5969069
nope, there's been lots of in progress images though, like an image floating around of the injector

i cant hold all this lack of data and results
they didn't even give a peek at the confinement geometry
it's basically vaporware
