>there are tens of thousands of astronomers RIGHT NOW who get paid to be nothing more than glorified photographers
Is astronomy the biggest meme of all time?
We haven't even upgraded space propulsion systems since the 1960s and yet we apparently know more about black holes, the origin of the universe, planetary and star formation and shit

"glorified photographers"
fucking kek
you're fucking retarded

If you go left or right on a map, everything repeats, but if you go up and down it doesn’t
Conclusion: The Earth is not flat, but a cylinder
>>7975803
Huh? It would "repeat" if you went from pole to pole though
>>7975807
On a map if you go off the left side of the screen you end up on entering on the right side again, but if you go off the top of the screen you don't enter on the bottom do you

What
Is it possible the Universe has existed forever?
As in, if we go back 17 trillion years ago the universe would still have been here. If we go back further, still here.
Why does it have to have been created X years ago?
>>7975799
Causality doesnt like it, but then causality doesnt like any of the options
>>7975799
yes u fucking retards
it's called predeterminism
and it's the only thing that makes any sense
sadly, people are stupid
>>7975813
Yeah man, infinite regress makes perfect sense
EXCEPT THERE'S NO CAUSALITY IN AN INFINITE REGREE
ITS A FUCKING CASTLE IN THE AIR
Tonight whilst myself and my partner were in bed she had her phone on charge whilst in her hands and I was watching a YouTube clip whilst rubbing her back, every time she had her phone in her hands I could feel tingling sensation in my fingertips like the electricity from the phone was conducting from the phone to her and when she put the phone on charge down the tingling sensation went away I was intrested to know if anyone on here could explain this for me.. We tried reversing the role so I had the charging phone in my hand and she rubbed my back but she couldn't feel...

Just the sensation of looove, family
Post nudes of you are waifu
>>7975761
Its probably in your head, skin resistance is pretty high
I done a few test to prove it wasn't in my head such as closing my eyes under the blanket and telling her to pick up and put down the phone without telling me and every time I could guess when she had done so
In school the teachers would say "blabla's weight is X kg"
Wtf? No.
Its mass is X kg and its weight is X N.
Why can't they introduce this concept correctly?

>>>/reddit/
because only perpetually incredulous autists like yourself actually care enough to nitpick a common parlance
...wat?
consequence cant exist
light coming from a star that has been traveling for 13 BILLION years, being bent and turned by gravity distortions and nearby galaxies, at that EXACT moment collides with YOUR eye and you see it
the odds of this happening randomly are ASTRONOMICAL
ergo, it was by design
visavis predestination
The universe is deterministic, the odds of anything happening is 1 in 1.

umm ok so roll a 13 billion sided dice and see if you guess a number right on your first try, and if you do, tell me its a coincidence
i dare you
>>7975615
I mean if you are smart enough you can calculate the throw or predetermine result, when throwing. Thats what is done in fact. There is just no creature smart enought to calculate it.

Is that the electronic configuration for indium?
lol, no

That says iridium, not indium
But thanks for trying
>>7975512
lol, I can't read, you're still wrong tho
Does the equilibrium of non-cooperative games almost always have a worse social outcome than the equilibrium of cooperative games?
I'm talking about games from game theory - a branch of mathematics.
>>7975430
Equilibrium is a meme. Your purpose should be to win the game not make comprimises to the enemy.
>>7975430
It depends on how "non-cooperative" we get. If we throw out human welfare as a basis of values for a given player, then the social effects will become rapidly negative around that player.
>>7975450
By social outcome I mean social welfare - a concept from welfare economics which is used to measure how well a society is doing as a whole.
Not the conventional normie definition of "social effects" as in effects on social interaction.
Why are you working for a technological future /sci/? Don't you realize it would be the end of all life as we know it?
Think for a moment about the implications of convenient space travel. If you could fly around the galaxy with ease faster than light speed, you could easily smash your ship or a large projectile into any planet you want with near infinite energy and utterly destroy all life on the surface. There is no defense against this. If a single person with a spaceship was having a bad day, billions will die.
Think about the implications of immortality....

>faster than light
Literally impossible
>immortality
Literally impossible
>virtual reality
Even if it happens, what's the problem? You said it's indistinguishable from reality, so it doesn't really make a difference.
Oh, what else are we supposed to do, continue being caveman faggots? That's just as stupid.

What's the weirdest function you know of?
The function that picks an arbitrary element from each coset of Q in R
Shitting. I mean, here you are, a being just casually enjoying your life. And your body just NEEDs to spit out some dirt. And you have to interrupt all these higher operations and thought streams to contribute to the stuff that keeps you alive, the most base element, through you fertilizing the plants and the animals eat the grass and the whole cycle continues with the shitlords demanding that you ritualistically shit pray to the shit we all are. Oh wait did you mean mathematical functions?
>>7975202
Yes. I'm sorry was this supposed to be a joke?
Is there a way to get swole without exercise? There's got to be a way to stimulate the chemical processes and physical changes that occur during an exercise regiment without the time/work. Myostatin inhibitors? Human Growth Hormone? Direct electrical stimulation of skeletal muscles? Pardon my ignorance; bio isn't my field.
Don't you think everyone would be huge if this was possible?
Steroids. A guy injecting steroids and sitting on his ass eating cheeseburgers will gain more muscle then the guy busting his ass at the gym four times a week without them.
no, completely impossible
Any homelab chemist fags in here?
How much did it fuck your wallet up?
Been thinking about a homelab for a while but in my city there is literally not a single place to buy anything, not even a beaker, and buying lab equipment from the internet seems is a little expensive
>>7975093
doing what tho
>>7975093
From time to time the labs at unversities change their equipment (got 3 free 1000 ml beakers this way and ground flasks, a friend of mine like 2 boxes of different stuff, even cool shit like soxhlet)
>>7975093
what are you trying to do with your lab?
What's the difference between a function and an operator?
>>7974898
I'm also interested in this as someone who doesn't have a math background
>>7974898
Operators are specifically between vector spaces
functions can map between any two sets
All operators are functions but not all functions are operators. A function which maps a piece of fruit to its colour is not an operator.
"Computer Science" courses as taught in universities can be broken down into two categories:
1. Software development: things like OS, Networks, Databases, Distributed Systems, Software Engineering 101, Intro To Fizzbuzz etc.
2. Theory: Automata, algorithms, complexity, AI, ML, etc.
The former is as much of a science as Engineering. The latter is as much of a science as Mathematics.

>The former is as much of a science as Engineering. The latter is as much of a science as Mathematics.
Engineering isn't science at all, it's solving problems using science, only rarely do we contribute to science directly (an example from my field would be Oliver Heaviside), it's mostly developing tools and ways for scientists to do the science part.
As for 2 I'd say it's true if those are done correctly, stanford's ML for example is cringe worthy
>>7974893
>And to each their own, personally I think Mathematics is a science, because even though it's a completely abstract construction ("it only exists in our minds"), it can be considered a non-physical property of the universe because our minds are a part of the universe.
You heard it here first, """"quote"""" fags think mathematics is a science and are therefore confirmed cancer.
>>7975354
For example, prove that some theorem is not true. You can't. Therefore math is a science.
What is the consensus on /sci/ regarding people with intellectual disability?
Should they be prohibited from participating in certain societal positions and activities?
> pic related

>Intellectual disability
>It is defined by an IQ score under 130
kek, well played. But yes, we should ban the brainlet for all forms of high office and anything above menial labour [spoiler]until we can replace them with robots [/spoiler]
Probably they should be encouraged to spend their time on websites like 4chan or Reddit, so that they don't unnecessarily burden normal people.
>>7974844
They should be sterilised if they're not already, and allowed to do what they want but not given any advantages
