Evolution doesn't work in terms of benefits. It works in terms of non-detriments. Scientifically speaking, humans aren't the product of billions of years of selection of beneficial traits and random mutations; we are the culmination of trimming out things that would result in our organistic demise.
That being said, depression could never proliferate enough to threaten our species.

>>12153982
Probably semi-hibernation that locks in with seasonal scarcity of food. You eat more when you manage to get it and lay around motionless in despair so you don’t burn it off. Of course, in the olden days Depression was much more bearable because you actually could just lay around for months and months of ice age winter, doing nothing but staring at stalactites listlessly, going for a walk in the snow, and occasionally keeping warm by snuggling with a busty cave woman as you eat from your massive supply of mammoth jerky.

What's the answer to global warming?

cont

Third paper is a pretty boring but in a nutshell it shows decreasing cloudcover in greenland has been accelerating melting ice sheets during the 2000s compared to the 80s. Which is kind of bad for you because again Mclean claims more cloud cover in the 2000s compared to the 80s which according to him should result in net cooling. This one isn't a complete self own as it's regional vs global, bit it's still showing the opposite of what you claimed. (reading again could have saved you embarrassment but it's fun for me i guess.)

4th paper is also interesting, but isn't it a little weird to link a paper examining how clouds react to warming from an increase in CO2 and if this is a negative or positive feedback when your entire argument is that CO2 doesn't matter? Kinda weird bro, again try reading reading your links first.

no idea, i only did up to electro statics and stopped, i dont even understand how circuits work at all aside from some basic understanding on conductor property's making 0 internal electric field because it cancels out somehow, if someone can explain the proof of that to me without using line integrals i will be very happy
>>
>>12166838
A conductor doesn't have 0 internal electric field, wtf? In DC current, electric field inside conductor is constant, the reason is that, if it weren't constant, the electrons of the metal would feel a force and rearrange themselves in the field in such a way that the gradient in the field disappears and the field becomes constant again. In AC current, you get a skin effect where the majority (actually depends on frequency, higher frequency, larger proportion) of carriers are located on the outside surface of the conductor, but this doesn't mean field is 0 inside either.

It is cold during winter. Doubly so during an Ice Age, which was last 100,000 years.

There are lots of posts on internet forums of people asking if they could study the material that is taught in an undergrad program of subject xyz within 4-6 months on their own.

Has any of you actually done that? Even though these questions are not as common on /sci/ than on other sites, I'm still curious whether people asking these kinds of questions actually then went ahead and put in the hard work that is required.

he did not say that. whether or not your hypothesis is true, you can feasibly simultaneously not believe in it and not like yourself. just because he says one, does not mean he himself is saying the other. you can't just interpret everything anyone says into being based on the "correct" assumptions

an analogy, a perspective - the same way you address physical inflammation, mental phenomena like "killing yourself" needs same attention

>I've already repeatedly answered this retarded objection. I am not using indeterminism as evidence for free will. That would be retarded. I'm merely using indeterminism to refute the main objection to free will, namely determinism.
The evidence of free will is of completely different nature: namely my immediate perception that I have free will.
you asked "What other ways are there?" (than determinism, for free will to not exist), I answered for all the indeterministic stuff just being random is a way for free will to not exist in an indeterministic universe. Don't blame me for thinking that you think indeterminism = free will when you phrase the question like that. And you claimed that you have "never seen anyone argue against free will without assuming determinism", when it has been many people's objection like Sam Harris or several in this thread that indeterminism is just randomness which is not free will. A common argument whether you agree or disagree with it.

Breathing is not free will you retard, it's an unconscious reflex that you have no control over. You can't decide today that you don't want to breathe anymore. Seriously 90% of the idiots in this thread talking about quantum shit have no idea what free will is or how it's defined. You are all talking out of your asses. Understand the biological definition first and then this thread will get interesting.
