Why the fuck are they trying to push arts into STEM, who thought this was a good idea?

Because of money most likely, I bet they just want to scam some more dumb kids out of a few grands. By associating their liberal arts degrees with something as prestigious as STEM they can probably get a few more pretentious dumbasses into paying for college.

once got a reply from a faggot who said Mathematica does not work with Cellular Automatons in it's core functions.

look on how it generates random numbers and then reply again you godforsaken imbecile.

Wolfram will be one of the most important persons of our generation regarding computational science and math.

it's sad most people have not even the slightest idea what they're actually have in front of them.

Can someone please tell me how you can solve this Sudoku without guessing (i.e. what mathematical principle can you use to solve this w/out guessing any of the remaining boxes).

I know the solution, but it's driving me crazy that I wouldn't have been able to figure it out if I didn't guess.

Please try to keep it relatively simple, I am a brainlet.

There is no mathematical principle, sudoku is an NP problem there is no formula for it, you need to brute force. As the amount of squares increases it's solution time expands exponentially. Unless you think p=np in which case you're a brainlet
>>
>>9036369
But with every other puzzle I've done (specifically this is the 'Hard' puzzle, from NYtimes) I have never had to guess before. So, I feel like there must be something I am missing, or some mathematical principle that I could use to solve one square.

There are mathematical rules that apply to Sudoku, for example: If in any row, column, or 3x3 box you have two smaller boxes where only 2 numbers can go, then none of the other boxes in that row, column, or 3x3 box can include those 2 numbers, so you can eliminate them from the other boxes.

I wanted to know if there is some principle like that I am missing.

At least I've found that in some cases you can mix partial derivatives and infinite descend to prove some inequalities involving integers.

I will feel dumb though. Kids out there don't even need to use partial derivatives to solve those problems. Am I a brainlet?

I have heard from a human sexuality class once that it is possible men of different races differ in penis size based on how wide set their women's vagina generally is in the population. So like it doesn't matter that many Asians guys have smaller penises since many Asian girls have very tight vaginas anyway. And many blacks have larger penises because generally black women have wider set vaginas.
If this is true, considering this compatibility, does it point to the idea that racemixing is generally not the best idea and definitely shouldn't be forced? Not on the premise of superiority or anything but on evolitionary physical compatibility.
Not trying to be /pol/ or aanything and say one race is inherently better to emphasize again. Just putting this lut there, obvious it's anything general trend and not every person conforms to it.

Where is racemixing forced? I don't think anyone's held guns to people's heads and forced people to fuck since Unit 731, and even then they were all Chinese
>>
>>9035674
I'm just saying. Like,sjw,are a,bit crazy sometimes with the whole, if you don't find a certain race attractive/aren't interested then you're racist,which is bullshit because it seems one sided most of the time. It's not like there aren't plentry of blacks for example just not interested in whites or Asians. No one calls that racist...
Besides that, I'm just saying doesn't that function as a type of signal that we definitely should never do that in the future? I think most people of a certain race find it easier to relate and associate with people similar to them since cultures and interests are also more likely to match(though not always).
Race mixing should be random and generally uncommon though not looked down upon obviously. If the peoole are doing it for the right reasons at least (love).

Can anyone give me a realistic projection of the effects of climate change in the next 100 years based on peer reviewed scientific journals?
50 posts and 8 images submitted.
>>
>>9035367
I don't usually read these papers, they're probably hard if you don't have background in the field, but from what I follow from climate scientists there's a disagreement between the future, therefore the answer is: nobody knows.
There's the side that believe the temperatures will continue to rise because of the increasing amount of carbon dioxide in the atmosphere and there are the ones that climate is mostly affected by the sun because temperatures have been increasing at a steady rate for about 100 years despite the concentration of CO2 increasing significantly since then. Some of the latter say we may be headed for an ice age and increasing carbon dioxide is actually a good thing.
If you want my opinion, it will be just about the same as it is now, 100 years is nothing

Its really sad that people do not discover the vast potential of psychoactive substances along with the science. They would contribute alot. As many of famous scientists were also experimenting with LSD. Today the shills and normies oppose drugs usage having little to no idea about it. But dont be mislead by this internet falsehood propaganda. The new times will come.

The biggest enemies to psychoactive research are the fucking stoner culture "I'm so high right now I shit myself lel" degenerates. I'd like to see more intelligent, influential people come out as being moderate users of drugs so this shit gets the respect it deserves again.

Michigan Kaku is the one that propagated the meme that endgame civilizations will create a new universe to escape entropy.

Stephen Baxter has a decent book on the matter. A man stays behind as what life remains in the universe flees to a younger one, and as he dies, he achieves nirvana.

Riddle me this /scil/
If advanced alien civilizations exist, then why is there no physical evidence floating in space

No structures of any kind, nothing. Even here on our world, past civilizations left behind immortal legacies that proved they were here.
Our telescopes are able to get hi res images of the pillars of creation but nothing proving that intelligent life exists outside earth.

Hello 4chan,

I've been working here for a while now

>nobody else in the world other than a few key people know about the shit going down here

basically they're about to cure cancer

Can someone please explain exponents intuitively? I get what they do and their properties but i can never really 'imagine' them.
11 posts and 2 images submitted.
>>
>>9037754
Intuitively, [math]x^y[/math] is the number of functions from a y-object set to an x-object set.

For example, [math]2^3 = 8[/math] because there are 8 functions from {A, B, C} to {0, 1}, i.e. there are 8 ways to assign a number to each of the three letters.

More generally, if X and Y are sets, then [math]X^Y[/math] can be thought of as the set of all functions from Y to X. To convert between sets and numbers, simply take the cardinality of a given set to get the resulting number, and conversely given a number just take a set with that many elements.

Disclaimer: Not guaranteed to work with complex exponentiation, ordinal exponentiation, or exponents involving 0 or anything other than cardinal numbers for that matter.
>>
>>9037754
It's literally just repeated multiplication. If you really need to visualize it, just look at a graph of x squared. The distance between each value is larger than previous.

What about them can you not imagine?
>>
>>9037769
Well then how can you repeat multiplication in 2^i?
