we are still so very very far away from anything remotely close to AI. we won't have AI till we basically create true synthetic brains, and thats not going to happen until we actually figure out how our brains work.

shit, we don't even have the power supply or linear actuators required to make a decent android, OP's pic is uncanny as fuck.

someone told me that self awareness of our own thoughts is like half a second slower than when they show up in an mri. Is this true? He said if he reacted fast enough he could say what i was going to say, thus stealing my trick.

Yes, it's true. Just google the studies.

It's must've been some sort of asshole who told you that. That's literally impossible.

The mind is a series of layers, a lot of what happens is actually automatic or handled by the subconscious. The conscious is only consulted when the subconscious doesn't have pre-programmed responses to a stimulus or situation.

A common example of this is when you are driving and you suddenly "wake up" and you're almost at your destination. Your subconscious has the basics of driving down to where you don't need to make a conscious decision for every little action. If an event occurs that the subconscious cannot handle, your consciousness is then...

Hi sci how to i know when to use the residual theorem or the integral cauchy theorem ?..

When you are to calculate a complex integral.

>>7811831
See
>>7810206

>>7811831
You're integrating over a circle. If your fucking function is discontinuous in the circle, you use the residue theorem. If it is continuous over and in the whole circle, the answer is zero. Fucking open your book for once.

What is the proper way to study anatomy, /sci/?

I am currently trying to study the muscles of mastication and the maxillary artery. How do I study so as to get a good grip on it? Do I need a skull set? Please help!

Hmm. I have a copy of ballieres anatomy from 1911. It is essentially fine sheets of tracing paper that provide 'slices' all the way through (in my case a heart). I see ballieres still exist, maybe that format still in production?

So someone has posed this question. If it actually has a logical answer, I cannot see it. Does anyone have any ideas? Or do you think someone has just put a bunch of random numbers together without any meaning whatsoever?

Maybe ? is a variable to solve for.

?^3 = 64.8
? = 4.o2 (my zero key is broken and I can't even close these brackets. fk.

If 0.999... equals 1 and the sum of all numbers is -1/12 then OP's equation might as well be true. Math is logical my ass. The system of numbers is flawed.

what's it like holding a PhD? what kind of hardships do you go through for a postdoc? is it just "research these areas of mathematics and see if you come up with something." or "if you don't find something by the end of this term i'm going to kick you to the curb."? i always hear about people being pressured, but i'm confused. don't you usually go into a postdoc already having a thesis or some papers in an area? or is that uncommon? what's the frequency for publishing theses on average for you guys?

nobody who has a phd, or atleast a successful one, is here

be that as it may, i'm hoping someone would at least have some insight due to unbiased research at their respective institutions.

You go into a phd if either you love masochism, are misguided, are golden boy with a fat stipend from some organization, or you are a foreigner.

No other reason.
