Males die more often because they like to do dangerous and stupid stuff like wage race wars and stuff.
This is why extra males are naturally produced to compensate. The sad thing is that Asians have been aborting girls for a long time in the past and that's why every Asian country has like 5% extra males.
In the modern world males don't usually die so often anymore so there's many extras that are probably becoming incels and shit. It's really sad being the disposable pack animal of the human race.

>imo it has more to do with the breakdown of marriage,

Stop, marriage means fuck all in this situation. In the majority of the world marriage is/has always been the equivalent to a business transaction. The men who get involved usually have no incentive to be satisfied with the women they have and often will cheat. The Women will do the same if they get the opportunity as shown in a number of first world countries.

The truth is males have always been more favored (or disposable depending on your perspective) simply from a "workhorse" point of view. The incel phenomenon as brought up by OP actually appears to be a situation where the males in question either,

a.) too lazy to move to other locations to find girlfriends/wives/mates

or

b.) their standards have become too high relative to the current status they're in.

The whole "Chad" excuse seems a bit too convient when the truth is the bulk of "Incels" bitching are first world males who could easily get a girl from third world countries if they're absolutely desperate. But most likely could easily get one in the next city over.

Inceldom isn't that confusing to me. Basically they are men that were bullied and abused as children and now they have mental problems as adults.

Moving to other locations is a massive financial and societal change. You can't just up and move in the hopes of finding pussy.

Complete nonsense. Every single study done on male dating habits shows that men will pursue an absolutely massive array of looks when it comes to women. This is why women are swamped with messages from men in all kinds of dating apps.

Why not? We literally do it for work all the time. All of a sudden it's not viable when it comes to finding a mate you can have children with?

>Complete nonsense. Every single study done on male dating habits shows that men will pursue an absolutely massive array of looks when it comes to women.

Reminder that massive array of "looks" means choosing between breast and butt size, brunettes and blondes, curly and straight hair, above average european, asian, amerindian and african women.

It does not mean the sub 5/10 girls with rarely groomed hair, facial impurities like blackhead scars, crooked teeth, overweight or obese, lack of fashion or color sense, economically poor or mentally scared. Shit that you could actually help a girl with if you put in the time and work.

>This is why women are swamped with messages from men in all kinds of dating apps.

No, they are swapped because women on dating apps represent a fucking small subset of all women on the planet. Billions of women exist on earth and yet you somehow think hundreds of thousands of women on fucking meme dating sites like Tinder count as the whole population? What the actual fuck is wrong with you people?

Calc 2 is a 2000 level class, I think linear algebra is 3000. Anyway, if you want to do well, start studying now. You'll have plenty of time to ask the teacher questions about the harder problems if you study in advance.

why do people gobble up fabricated models on climate change with variables tweaked for the desired outcome?

>>10734516
>Oh youre an entitled boomer who would rather see everything go down in flames than be mildly inconvenienced.
And there's the third thing that pisses me off when it comes to discussions of climate change: suggestions about how we can fight climate change which are utterly and completely ignorant about the realities involved and are therefore off by an order of magnitude or more.

Let us assume that the IPCC's worst case scenario will come to pass. Let us also assume that the entire globe has decided to "do something" about climate change. Every nation and people and religion all on board.

You can take your fuel efficient cars, your bicycles, and your city planning and choke on them. Nothing short of getting the ENTIRE GLOBE on fission power and electric vehicles within about 25-30 years will make a real difference in the warming curve. That would come at a cost of trillions of dollars per year and would involve handing state actors like Iran full access to reactors that could be used to make weapons. Since industrializing nations can't pay for this figure about a third of your current take home pay or more going to this every year for the next 30 years.

You ready for that? Because driving a Prius on today's grid while buying local produce and tweeting about loving SCIENCE! isn't going to shift the warming curve by even a day. You have zero clue of the scale of the numbers involved if you believe anything presented so far, including Kyoto and the Paris Agreement, would have an observable effect on warming. Or if you believe actually getting off carbon would only be a 'mild inconvenience.' I've run the numbers and plotted the graphs. Every idea politicians are willing to float is equivalent to shooting a BB gun at a hurricane.

Fortunately observation shows climate sensitivity is not as high as we feared and there's more time. Because otherwise we would be SOL.

>>
>>10735712
You are correct that government action is the only way to actually make a dent in emissions. You're incorrect on other things. Net zero emissions by 2050 will limit warming to ~2C which would be a best case scenario, but doing nothing puts us at closer to 5C by 2100.
Significant government action in the form of a carbon tax etc, more aggressive tax credits for EVs renewables etc can shift us into the 2.5-3C range by 2100 without causing significant economic damage which wont be catastrophic. As for climate sensitivity being lower you'll need to provide a citation.

>cleaning data is cherrypicking
Adjusting for all these variables to get an accurate measurement while keeping track of uncertainties is like a statistical miracle. Climatologists are literal geniuses and then you go and say they're lying.

you can't. You can't build a PWR without enriched uranium which you, for all intents and purposes, cannot obtain as a civilian. You could build something like chicago pile one or a CANDU reactor, but in either case you need literally TONS of uranium. You need TONS because that's what it takes to obtain a critical mass with natural uranium. The americium in smoke detectors is enriched to the extent that it's weapons grade, but in order to obtain a critical mass of americium you need all the smoke detectors in the world. Also the radioactive boy scout is a lie. Kid didn't come close to obtaining critical mass, everything became radioactive cause he put a bunch of radioactive shit together. You could make an alphavoltaic generator by putting a solar cell on to the americium from a smoke detector. You'll generate a small amount of power for less than hour, at which point the solar cell gets destroyed from alpha radiation.

We have this thread all the time and the answer's always the same. Since the jannies removed a post that said this, and surprisingly not any of the fucking schizo spam, you should invest in solar(from the sun) instead.

Don't know why anyone would want to spread Ebola around in the first place. It kills hosts super-quickly so it's not like you're going to get a global epidemic out of it.
I'm more interested in if the Chinamen working on CRISPR can synthesize an airborne biological weapon that gives people Down syndrome.

i have a few gay friends who i originally knew as straight bros but they changed sides. i never say anything because hey, that’s totally and unironically fine. but if i had to win them back to being straight it would probably be a clear “argument” (or rather showing them pics of hot chicks and not even arguing anything)

for trannies i donno, but my best impulse is to say:
>look, you have a dick
>does it ever get hard?
>oh really it does. from what?

then it depends on the answer. a mtf tranny will probably say some gay shit, in which case the answer is just “you’re gay! i support that!”

occasionally there is something about “i don’t feel like i’m myself” and in that case i would try to convince them that HRT is not a replacement for biology. getting the insurance companies to fund big pharma’s attempts at synthesizing hormones is not a good thing to support. modulo that i try to argue that there are total woman gay dudes, and modulo that i’d say that cutting off your dick and removing the flesh and then creating a deep incision to stitch it into doesn’t make a cooter. if they can get past that then whatever, i give up

How does /sci/ remember and keep track of a bunch of information from a class in their head?

I'm taking a 4 week partial differential equations course right now. On our first exam today, I couldn't remember some of the basic shit from ODE class I took exactly a year ago but could do the initial boundary value problems just fine.

Because this PDE class is condensed, it feels like concepts are starting to blur together instead of being clear and distinct yet also related. I've made perfect scores on all the homeworks so far but that doesn't seem to be enough to make things properly stick in my brain.

You're right, the theory in this field is " behind " the practice. This is increasingly true for many fields, as getting funding for theoretical stuff is a nightmare and, often, downright impossible.
The point you bring about AI students is very true, but I think it's indicative of a field that is generally not meant for academia. By that I mean that most students learning CS/AI/Data science, you name it, are in because of the hype train and the prospect of a job.
From there, you get an overload of those people in the industry, and very few who take the standard research route as in other fields.
This leads to people that apply what they learned to problems that don't necessarily need to use ML or AI in general, pop a nice graph as you say, and feel good about what they have accomplished.
The danger lies more in the "trendy" aspect of the field. You now get a situation where everyone and their mother is into ML : in academia because you need to get funding, and in the industry for marketing purpose.
Overall, it's densely crowded, and not in the way it should be.

You have to show that the brain is a Turing machine, which isn’t super easy since we can perform NP-Hard tasks in P and there’s an overwhelming amount of evidence to show that P [math] \neq [/math] NP in general, much less anything actually harder.
You have to define a computation on “”””input””””” by the brain
You have to prove an isomorphism between computation by the brain to a computation in an ML algorithm
You have to show that the isomorphism is computable in polytime

All of this points to ML being simple approximations of neural behavior. It’s almost like somebody designed them with that in mind! They’re not like Fourier coefficients; you can’t decompose all cognitive tasks to known ML techniques
