Hello, fellow /sci/entists.
So I'm currently studying nuclear physics, and today I came across the story of Hisashi Ouchi for the first time. For those unfamiliar:
https://en.wikipedia.org/wiki/Tokaimura_nuclear_accident
http://www.cnic.jp/english/newsletter/nit128/nit128articles/jco.html
Ouchi was exposed to lethal levels of radiation and kept alive by the government for almost three months against his will to see what would happen.
The morbid details of his death aside, I'm mostly interested in the cause of the accident itself. According...

Bumpin for OP
just read the wikipedia
>> using uranium enriched to 18.8%
>> 16kg of uranuim
that seems like a relatively large amount of enriched uranium to me

Why aren't you devoting all your time, energy, and spare income into AI development?
Even if we get another newton, Einstein or hawking their lifetimes are limited, an AI with their capabilities has the capacity to go on forever.

I don't have the resources, yet.
>>7759304
I don't think we'll have it for awhile, and even when we get it, it will be locked behind an expensive paywall, which means that it will still be useless to me.
Sci help me.
>think i'm smarter than everyone.
>Know at the same time that i'm an idiot for believing i'm smarter than everyone.
>Still constantly find myself looking down upon others as though they're dumber than me.
This drives me crazy to the point of wanting to end my shit.
This can't be due to me browsing sci since it's been going on for a long time. Is there any way to cure cognitive dissonance?
Drugs it is.
Find some sort of math/science competition to undertake so you have an objective measure of how your intelligence compares to others.
>>7759261
Put yourself in an environment where you are challenged by like-minded individuals. You then will have a more steady view of your own intelligence, even doubt it.
How do I become better at math? I absolutely hate math and I am not very good.
>>7759219
If you hate it, you won't be good at it. Go in with an open mind.
Honestly I'd suggest starting with some basic proofs, they're confusing but really intriguing. If you acquire a taste for it you'll naturally want to build your skills.
Why do you want to be good at it if you hate it?
>>7759219
>not using that hate to gain power
Is there such a thing as a maximum "resolution" (for lack of a better term) that the human eye can perceive without external devices?
>>7759146
circa 0.1 millimeter
>>7759152
You mean 100 microns, faggot.
>>7759164
I actually meant your mom
How do I stop wasting time with video games and sex and bullshit and dedicate my life to acquiring knowledge
vote for trump
Can you teach me how I can waste my time with sex?
>>7759082
start hanging out with girls who are cooler than you and dont want to fuck you. once you realize they're out of your league you'll get butthurt and work harder until they're in your league. repeat
How to git gud at chess?
>>7758894
by talking about it theoretically, and never playing it
Play it a lot
>>7758894
Generally same as any other thing imaginable. Practice
Hello, /sci/, no dark matter guy here again.
This video is about the terribly wrong interpretation of the Eddington Finkelstein coordinate light cones and why they mean that our black hole model is wrong.
https://youtu.be/jNqOnpWjBx8
SSSB
Can you explicitely state what your problem with EF coordinates is?
I also don't follow your video or the naive explanation of why space must go somewhere and what it means to 'add' a lightcone. Afaik EF coordinates are just frames of references that eliminate the trivial singularities of the metric and as a result the lightcone 'tips'
bump coz im interested
From an external perspective, is there a near perfect image of the whole surrounding universe near every black hole's event horizon?
How "lossy" is such an image? Does spaghettification (etc) distort it very much?
Are black holes perfect circles?
>>7758812
No, there's turbulence on the event horizon's surface.
Possibly strongly governed by a type of fluid dynamics.
>black hole fluid dynamics
i don't even wanna imagine what the math looks like
Hi /sci/,
do you think there are still discoveries and worthy inventions that anyone can do on their own, or at least with small budgets?
It feels like any new invention or important scientific success is only in hands of relevant Unis, government or corporations with huge teams and millions to spend.
Do you see any relevant discovery in the next few decades happening in a garage? In what field? Do you play with any idea? I wish I was smart enough to make rockectless space travel a reality, for example.
There probably lots of material specfic macroscropic behaviours (e.g the mpeba effect) that you could find with a simple setup.
a lot of mathematical solutions are, the guy who proved that you cant have pythagorean triplets when the power is more than two was alone and didn't have millions (at least not until he proved it)
also rick sanchez built a flying saucer out of garbage he found in the garage
How does /sci/ feel about nomogenisis?
>Berg is most well known for his evolutionary theory called nomogenesis, which was a type of orthogenesis. Berg's ideas were collected in his book Nomogenesis; or, Evolution
>Berg distanced himself from both Darwinism and Lamarckism. Instead he proposed the concept of directed mass mutations as the main mechanism for directing evolution.[6]
>J B S Haldane called Nomogenesis "by far the best anti-Darwinian book of this century".[9]
>>7758749
I don't get something. Bear in mind I don't know skite.
Evolution is random. E.g. favorable mutation are passed on while those that are not die off. But can a species naturally influence mutation besides members with favorable mutations breeding?
Here's a stupid example:
>human
>want to survive underwater for longer periods of time
>larger lungs as a result
Are the genetics for larger lungs passed...

Genes are changed.
Are the legitimate strategies for placement and shooting in battleship (other than 'don't shoot where a ship wouldn't fit in' of course), or is it all just randomness and maybe a sort of bluffing-type metagame?
>>7758328
make them all touch alongside the borders or put them all in one corner/side
those are the only two strategies I know of
>>7758328
and if you are shooting do it in some pattern eg
start with j1 -> a10 leaving two spaces, after each shot, then do a1 -> j10
after you hit a big one with a two-space pattern switch to a one-space pattern
>>7758328
git gud
Was mathematics created or discovered?
depends on how you look at it
>>7758293
why do you care faggot you probably don't even know calculus
>>7758293
Was you asking this question an act of free will or we're you compelled?
Compelled by memes?
If matter cannot be created or destroyed, and only be changed from one form to another, where did matter come from in the first place?
>>7758291
Matter can be created and destroyed, energy cannot.
>>7758299
where did energy come from then
>>7758302
No one knows.
What are your thoughts on this guy?
>>7758185
cool guy. A little bit autistic but hey, who isn't
>>7758185
He's ugly and his videos are only appealing to underage fags.
>>7758191
Autistic or aspie? What's the difference?
