How long away is full gender change at will? I'm not talking about chromosomes or reproduction, just the way you look and sound. How long until I can look, sound and feel just like a woman, with vagina and all, but still have my male brain, no menstruation, prostate etc?

Previous thread related, notice how that one moron posted links that directly contradicted his argument and then never responded back.

By the way OP, Churchill has average temps ~-13.9°C for the month of march, and on average it doesn't get above freezing until May / June there, so once again your argument boils down to "Wow, it's snowing in winter again! Warmist BTFO!" yet again.

The square root is defined in terms of the complex logarithm which can only be defined locally
https://en.wikipedia.org/wiki/Exponential_sheaf_sequence
>The exponential mapping here is not always a surjective map on sections; this can be seen for example when M is a punctured disk in the complex plane. The exponential map is surjective on the stalks: Given a germ g of an holomorphic function at a point P such that g(P) ≠ 0, one can take the logarithm of g in a neighborhood of P.

Is the simulation of a system equivalent to that same system? More specifically, if we simulate a consciousness, is that not an authentic consciousness?

That is more a philosophical question "perception is reality yada yada" Also the simulation is almost never as good as the real life, a simulation is based on reality as a way to make prognosis for something.

Is the ship of Theseus Theseus's ship?

Well, it's a ship. Close enough.

So, yes, for most purposes. You can always engage in epistemic pinhead-dancing, but for perceptual purposes, identical is identical.
>>
>>8761711
How many angels can balance on a pinhead? There is no meaningful answer to your question.

Itt we tell describe how we study, and what the best methods are for optimal learning in quantity.

A good way to study is SQ3R: survey, question, read, rehearse, review.
I tend to skip the first two steps or half-ass them

Another good idea is to take several short breaks and infrequent long ones. One popular methods is 25 minutes studying then one 3 -5 minute break. Every 3rd or 4th break should last 15 to 30 minutes.

What are some other ways to stay motivated and optimize learning time?

back when i had to study for uni exams I did this:
pomodoro with 50 mins of studying / 10 mins break (I read a study that said that after 1 hour it becomes harder and harder to pay attention to a subject without losing focus)

during the breaks I'd do some jogging, pushups, etc calisthenics because physical activity reduces stress, increases focus

if I was a bit tired I'd eat coffee (fuck boiling it, if you eat it you absorb 100% of it), I was too lazy to buy pills

piracetam, 4.8g every (biological half life duration) hours and before I'd take it I would eat food that is a source of choline: eggs, meat, dairy, etc

good nutrition, this is very important, to prevent mental fatigue and brain fog and short attention span and depression and anxiety and other shit

no distractions, repetitive, minimalist music (peter glass - glassworks as an example, or other electronic music)

clutter-free, comfy studying environment with good lighting


try to make as many mental connections as I can so that I can try to asymptotically reach the kolmogorov complexity of the quantity of information I need to memorize, basically I would try to do some shitty mental compression like ZIP, LZMA and etc do, I'd try to do shit like "oh so it's like this because of that and I can use X to describe Y and it also looks kinda similar to Z even though they're different"
and lastly, I know this may sound stupid, but I'd put some perfume on, I had anxiety when I was wearing that perfume because it meant that I had to go on and I hate that, because I had social anxiety, and wearing it at home would be some kind of CBT, i'd start to get used to it, also, smell is strongly related to memories, ever noticed how after sensing a familiar scent you start remembering all kinds of old memories? I wanted to make a mental association between the memories related to studying and the exams, so that at the exams when I was smelling the perfume I'd get a boost on remembering, like some sort of vidya buff

I think the general idea is to maximize the amount of information your human brain is capable of learning in a period of time, and to do this you have to think about how brains memorize and remember things. You have to do some research and optimize your life in such a way that you create new synapses that help store the information you want to learn and you have to strengthen them as much as you can, while avoiding distractions that cause new, useless synapses to form and basically slow your progress. Also, the brain constantly tries to compress the information by creating links between newly learned ideas and other, older ideas. The more mental links you make between concepts the easier it is to memorize and understand them. The more you abstract and describe them with different analogies, the easier it is to memorize them. You have to take advantage of every part in the brain. Language, visual, physical (tactile / locomotion, etc), olfactory, etc. All can be used to remember things.


besides this I'd try to become like some sort of autistic robot, by this I mean that i'd try to force myself to stop thinking that I'd need breaks or entertainment and that studying was everything I had in the world, I'd try to make studying my entire life during the hours I'd study, I think this sort of mental conditioning is very important. Let's say you're a pathetic brainlet that's being mentally controlled and subjugated by the social network jews and you check facebook half of the time. You halved the amount of time you have available for studying. That shit is far too inefficient.
>>
>>8759527
also I think that it's best to really work your ass hard when learning the base concepts because it is important to get the basics really well so that the future blocks of information are really easy to understand and memorize because you can just use the base blocks to describe them, usually, if you are able to create mental connections between them and analogies and other shit

I don't think the card / question crap is that useful

in my opinion it's more useful to think about learning in a human way, not in an abstract, machine kind of way where you need to test shit continuously

and you can do this by drawing diagrams, thinking in an abstract way, making lots of mental connections, making analogies, trying to explain concepts to yourself in different, simple and complex ways, etc

I've got a question about the Four Color Map Theorem, just because I watched Numberphile [ watch?v=NgbK43jB4rQ as the link to the video in question ] And I made this as the only map I can think of that is close to violating it, but the problem is I'm almost positive it doesn't, and that it can be filled in with just 4 or fewer colors. Second problem is I'm a little tired and I'm sure I'm just not looking at it with clear eyes. I've got the network made, I think accurately, I just wanted to see how quickly you math and science nerds could solve / fill in the map such that none of the zones share a color with any of the zones they border. I know there's a solution and it's probably pretty obvious.

Everyone knows that not all colleges are the same, but what are the dropoffs from, say, a top 5 to a top 10? Top 10 to 15? 15 to 25? Or how about 25 to 50?

For undergrad, there's no difference in the quality of education being offered (within reason).The "top" schools are research institutions, not teaching facilities. You'll get the same level of education for CS (kek you fucking brainlet) at penn state that you would at Berkeley. I mean, there are only so many ways to teach the pigeonhole theorem and how to compute permutations to undergrads.

Prestige of course differs, and the Berkeley grad will symbolically outrank you, but at the end of the day, you were both taught by an overworked grad student and probably Pompous phd who view your education as nothing more than a nuisance.
>>
>>8765287
This. The level of education you'll get is virtually identical. The difference mostly comes from having a good name on your resume, it will open more doors for employment.
