I LOVE nonlinear dynamics.
Lets discuss nonlinear dynamics in this thread.
Anyone have much experience in that field?

this is just a sad branch of math to say that we actually don't understand the system well enough to model it

If you actually want to try and understand nonlinear systems, then something like pic rel is needed.

What is the most likely way we could achieve immortality (if it were possible at all)? Transferring our consciousness to a machine, cloning of a new body, or what?
I personally think there's a hard limit on the biology of the age of the brain that will render any form of biological immortality impossible.

I don’t think I’d want to live forever, if such a thing were possible. Don’t get me wrong, life is good and all, I just think after 80-90 years maybe it’s time to hang up the spurs. I wanna know what’s beyond… if it’s infinite nothingness so be it. Plus could you imagine how horrible this world would be if everyone who ever lived kept on living?

Immortality is the absence of entropy
Entropy is an axiom
Therefore immortality is no possible (unless you are God, praise him)

a way to just repair and replace brain cells would be preferable. that way you continue on feeling like a regular human. consciousness is spread out to different parts of the brain, you have different types of memories in different areas of the brain. different areas control different functions. I do not know if there is just one spot where the soul is, but if I had to guess, I suspect its somewhere around the brain stem. my worry is that replacing areas of the brain could remove whatever that part is we consider the soul. and I wonder if there soul or consciousness could really transfer to machine parts after being connected to our nerves and being part of us a long time. I'd feel safer replacing every other body part aside from the brain with machine parts. but, if we do ever discover that we could ship of Theseus our brain with chips that do the same functions as those regions over time, and that our soul or consciousness could integrate it, I guess it would be alright.

If sin is real, then punishment is just and cannot be escaped. Salvation thus cannot be purchased but through suffering. If sin is real, then happiness must be illusion, for they cannot both be true. The sinful warrant only death and pain, and it is this they ask for. For they know it waits for them, and it will seek them out and find them somewhere, sometime, in some form that evens the account they owe to God. They would escape Him in their fear. And yet He will pursue, and they can not escape. (https://acim.org/acim/en/s/505#2:1-7 | W-101.2:1-7)

Fortunately its all imaginary
>>
>>16956224
Nothing imaginary about it when real polynomials (real x and real y) necessarily must have imaginary roots in another dimension. There is information encoded in real polynomials graphed in the real plane that tells you about the imaginary roots. All math textbooks since Hamilton hide this fact by going from real polynomials straight into complex polynomials and just pretend that (x,y)=x+iy

A high-school student can make a fuseor in their basement achieving similar flashy metrics. Just because its hot doesn't mean it's putting out more energy than you put in. PE startups and governments love to use the "hotter than the sun" line when they have nothing but a fuseor.

What happened? There was an announcement and some interviews about it for like a week or two last year, and then they went silent. Try searching up "majorana 1 update" or anything related to it, you'll only see posts from the first month it was being talked about on the news. Did the pentagon or defense contractors pick them up and made them all sign NDAs or what? They promoted the chip like it was going to solve everything classical quantum chip design was failing on.

Accidentally put a hole in a li-ion glued bphone battery when I was ripping phone components apart like an ape. Fizzle and flame, bitta black smoke, run outside holding breath and sent it as far as I could.

Collected it like I was a Spetsnaz juggernaut hiding behind a bin lid and dropped it in a bucket of water for est. 3 weeks.

Fast forward, empty water and battery has gone pillow swoll. Do I just submerge it back in water until I can safely dispose of this thing? Is there much risk having already punctured the battery/letting it sit underwater for a few weeks?

anon would like to keep both of his hands

What's the real deal?

People always say that "Iq only measures how good you are at taking IQ tests" but idk my dudes... That just sounds like R*ddit cope.

Because if you talk to an 80 IQ brainlet and a 130 IQ guy, you can tell the difference, right?
There's a very noticeable, observable gap.

Child IQ doesnt mean too much because you could have been quick to mature compared to the average. 135 IQ by itself also is not that smart. I think 155+ is smart, smarter than me. That said mabe you are that smart, I dont know, but its unlikely

Because for one to return they have to turn around and that requires acceleration. Velocity is relative but acceleration is not.
>>
>>16953174
Because to measure a clock you first have to observe it, the information about the clock on Earth will always be available to B, both when leaving and returning, just that when leaving the clock on Earth appears to slow down when moving away and speeds up again when you return until normalized, but when measuring the clock on the spaceship from Earth it will appear to tick slower as it's moving away and when it starts to come back it will still tick slower at first, since the information about the return has to first reach Earth, the discrepancy isn't in the clocks themselves, both will actually read the same time when reunited, the discrepancy comes from the apparent measured difference between two observers due to the information delay between them.

first of all, get your axioms correct about intelligence. 160+ doesnt exist i dont care about what HRTs you are talking about they're all frauds including langan. a HIGH FSIQ IS 95+ the average phd is 80s FSIQ, so dont give me the 130+ bullshit as far as im concerned im 130 g and 135 g tested at childhood. a really high g is 120 at that point you can discover something in your field after getting an ideas passively while studying you dont even have to master a subject to get ideas, intuition comes instantly and ideas flow like butter when its taught correctly or if the person on the receiving end is JUST intelligent enough to paint the picture themselves after a few repetitions. this facade of a high iq is bullshit, everyone on the internet cheats and most of them are incels that use the devil to do better on iq tests its fucking infuriating none of them will ever achieve anything either. you dont need 16-20 hours of studying a day to be like ramanujan, why? he DIDNT EVEN EXIST. the entire US gov has been re-writing history to fit the alt right narrative which is fine, but misleading thats all ill say since you are so naive
