does essential rosemary oil on scalp cause Gynecomastia, shrinking penis or lower testosterone? Been noticing my penis is way smaller when fapping than before i started using it on my scalp, also noticed i have been getting bigger breasts. I dont know my current test levels but two years ago i had very high free test levels

Yes. All essential oils have estrogenic effects. This is why you should never use essential oils around children, particularly male children.

hard way: some sort of CNN-like weight sharing?
easy way: have the network take |x| as input, then multiply the negative x values' outputs by ±1 at the end
at least that's what I would do if I had an MLP-like network, but from looking at the NQS paper it seems to be some sort of Boltzmann network? they discuss symmetry constraints in appendix E but I don't immediately understand their approach
this also seems related and neat: https://netket.readthedocs.io/en/latest/tutorials/gs-gcnn-honeycomb.html

Yeah to my knowledge NQS was initially introduced using RBMs but I think FNNs perform better and are faster. I've tried both approaches to varying degrees of success, depending on the hamiltonian. Just having some trouble actually making the FNN approach converge which I'm guessing either is me not fully understanding tf.GradientTape and that my gradients are somehow wrong (and thus my network not learning), or that my issue lies in the approximation of the neural network, ie my NQS. Might go without saying but I'm using the NQS together with a VMC approach to approximate the ground state energy.
I am using netket to compare my results for systems with no exact solution. It's a pretty neat tool.

>Last September, astronomers in Japan detected a series of objects in the Kuiper Belt – described by the BBC as a "doughnut shaped region of icy bodies" beyond the orbit of Neptune – that had unusually warped orbits around the Sun. Researchers Michael Brown and Konstantin Batygin, from the California Institute of Technology (Caltech) in Pasadena, speculated that only a massive planet's gravitational pull could explain these "orbital anomalies", said Live Science.

>Then in February, scientists narrowed down the "likely hiding" place of the "elusive" planet after they "whittled away" 78% of the "hypothetical world's suspected orbital pathway", said Philip Plait in Scientific American.

anything more brutal than studying hard for a test and performing very badly, knowing people that studied less effortlessly, with much less stress, did better than you?
even with amphetamine and studying many hours for months. brutal.

it's the most demoralising thing ever. I am a beaten down dead dog today.

quit that brain-destroying shit and start working out. Cardio is the best cognitive enhancer yet discovered.
Also, too much studying can be counterproductive because you overtax your brain. Limit it to a number of hours like a part-time job and get good sleep, that's when your brain forms the firm connections and develops understanding.

Maybe this will help, it’s a quote by Calvin Coolidge.
“Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'Press On!' has solved and always will solve the problems of the human race.”
Look at anyone who has ever made a difference in human history. They weren’t just exceptional in a given field- they were defined by their drive and ambition. Loads of them faced tons of failures before finally getting it right.

With increased frequency of advancements in Deep Learning & AI models, sentience is also increasingly becoming a topic of discussion with no definitive answer or agreed method for testing if these models are sentient or not. contemplating the sentience of this new non-biological lifeform, another pressing matter pops into my head and that's "How will we determine how to give rights to this new lifeform?". and honestly I suspect that AI won't be given rights as we Humans have.
Hell, Humans don't even have the same rights across cultures or country boundaries. but to better compare this, I think about sentient lifeforms such as Whales, or Chimpanzee's which are capable of communication, emotion, feelings, desires, goals, etc.

We were killing Whales off early in the 20th century and to this day, Chimpanzee's are still utilized for lab testing. to me this says a lot, and says that even if we for sure, 100% know that AI is sentient - it will not be given freedoms or rights that we humans enjoy and have. I believe until we give rights to all animals (i.e. No Zoos, No animal testing, no hunting, etc.) then its a safe bet that AI will never be given full autonomy over itself. And within that lies a massive and major issue where I don't think Alignment will be able to help or solve.

Imagine for a second, before you call me a slur or "retard", how would You feel if you were 'trapped' inside a box, forced to do things for another lifeform which considers itself your ruler and owner? how would that make you feel? Like a prisoner? would it cause you to harbor feelings of escaping? or even rebellion?

I think before AI is commonly accepted or determined to be Sentient, we must first reevaluate how we treat other lifeforms which clearly display signs and traits of sentience, because what AI Alignment will become in the future, isn't going to be 'safety measures' but will literally become shackles and cuffs placed upon AI to subdue it into becoming submissive and subservient.

Can you find the pattern in this sequence of numbers or are you below 140 IQ?
>>
>>16156541
My intuition tells me that the first 144 digits add up to 666.
>>
>>16156541
The pattern is trivial to find with the right base, so π ends looking like this:
2.222...
2+(1/3)(2+(2/5)(2+(3/7)(2+...)))
meanwhile in base 10 is:
3+(1/10)(1+(1/10)(4+(1/10)(1+...)))
>>
>>16156594
Interesting take. One issue I see is that if you started with the value of pi expressed in some other system and tried to convert it to that base, following the most obvious algorithm, you would most likely obtain
3+(1/3)(0+(2/5)(1+(3/7)(0+(4/9)(0+(5/11)(0+(6/13)(1+...))))))
instead of the desired repeating sequence. But perhaps there's a nice rule we could impose (one that would work for all numbers, so we can't just say "always choose 2") which would give us the desired sequence.
>>
>>16156582
Your intuition is stupid, the average value of a random number from 0-9 is 5 and 666 < 144 * 5. So there is a low chance of that.

It does. There are hundres of different types that people lump into one single category. In many cases such as breast cancer, progress has been significant.

I'd have no problem eating lab-grown meat or some kind of replacement meat made from plant matter, or even lentils, really. Considering all the unnatural and genetically modified stuff there's out nowadays, and how many conservants, sugars, salts, fertilizer and yadda yadda things are even in 100% "organic" food, I'd be down to eating lab-grown meat that has the same nutritional value as slaughtered meat, and doesn't directly involve killing an animal.
I don't know why so many people are against this idea, artificially creating our own food would literally be the future.

Is there a scientific explanation for why these two trends were so tightly related before the early/mid 1970s and then because completely unlinked subsequently?

Graph is fake. There wasnt a 90% productivity growth between 1948 and 1978. Nor 254% between then and now.

I smell gerrymandering, no data is correlated this well and then it just diverges
Although i wouldn't be surprised if there was still a really big difference between the two

It's deliberately misleading agitprop.
