What is the best way to compute the nth digit of Pi, when n is really big?

I don't need any previous digits, so they don't have to stay in memory or even be computed if it is possible to do this without them.

If I figure this out, I will use Pi to give Kurumi MaidCard III more powers.

Additionally when looking at advanced Computer Science research about Pi, a maid said it is "normal" and that this means digits are distributed evenly, so all possible finite sequences of digits exist inside Pi.

She said this is conjectured about Pi. Is it known to be true for any numbers easier to compute than Pi?

The goal of computing this is to use stretches of Pi as keys for a one-time-pad. So it isn't needed to send a very long key, or keep a shared random data file to make the key.

This also makes it so OTP can be used for file data of any length, since Pi has infinite length.

Thank you /Sci/entists for reading my post.

The Janus Cosmological Model (JCM) - theses validated:

1. JCM provides an explanation of the phenomenon of the cosmos expanding.
2. JCM explains the absence of observation of primordial antimatter.
3. JCM describes precisely the nature of the invisible components of the universe (antiprotons, antineutrons, anti-electrons, of negative mass, etc.)
4. JCM is able to predict that the antimatter which is created in the laboratory will behave just like normal matter in the Earth's gravity field.
5. Because in the JCM model masses of opposite signs repel each other, the latter are pratically absent in the Solar system.
6. JCM provides a clear schema for the formation of the large scale alveaolar structure of the Universe.
7. JCM explains the repulsive effect of the Great Repeller (a structure discovered in January 2017). The escape velocities of galaxies measured in the vicinity of this region are due to the repulsive effect created by the presence of a conglomerate of negative mass.
8. JCM explains the confinement of galaxies as well as the leveling off of their rotation curves, indicating peripheral super-velocities, as was shown recently by Jamie Farnès of Great Britain.
9. According to JCM, the observed gravitational lens effects are principally due to a confinement effect of the beams through the environment of negative mass which surrounds galaxies and galaxies-clusters.
10. JCM provides an explanation of the fact that far-off galaxies, with a strong red shift, have weak magnitudes, making them appear as dwarves. The light which they emit, when travelling through conglomerates of negative mass, finds itself diffused through an inverted gravitational lens effect.

It is no longer necessary to invoke the existence of a mysterious halo of dark matter nor black holes, as does the current dominant model.

Why is medical progress so slow? I thought the social contract I signed was I had to live in a shitty socially unequal dystopia, but in exchange for that, medical research would rapidly advance. Are there no billionaires with incurable disorders? Or who realize they are likely to acquire one? Or who are dealing with the inevitable ravages of aging? If I was so rich and I had an incurable medical problem I would dump hundreds of millions into researching it.

>there's no evolutionary purpose as to why we have dreams when we sleep
Why did evolution give this? What a scam. I keep seeing cope theories on how it is supposed to teach you about dangers and what not but that's all bullshit because most dreams are completely mundane and teach you nothing about your surroundings.
Most neuroscience is bullshit either way.

 >> Anonymous Mon Aug 12 13:24:55 2024 No.16321308 One of the best theories I've heard from a fellow biologist with a keen interest in neuroscience is that dreaming is meant to simply activate neurons. Neurons tend to have a crazy high plasticity and the ones that are not used for some times get "recycled" for something else (e.g. after a brain damage you can still recover part of the lost functionality by "teaching" other neurons to do the work of the lost cells). But you don't want to "recycle" neurons that are used for vision or other critical tasks and so you need to keep them active all the time. That's probably why you dream: to tell your brain not to recycle your visual cortex

Besides: if there are years of sensory input stored as memory there is no difference between an experience based on memory and an experience based on outside stimuli.

What are essential cs skills for math majors to break into tech after graduation? I know nothing about programming or data structures/algorithms but i am very interested in pure maths and I want to be employable after graduation, preferably into the software engineering route.

ITT post instances of bullying from the scientific community that pushed a scientist to suicide/death

 >> Anonymous Mon Aug 12 10:35:37 2024 No.16321132 There's a story told by a Dutch scientist whose name I can't remember and the story might have been scrubbed from the internet because I can't find it but maybe you can verify the following: once upon a time the so-called bathtub analogy of obesity was the dominant narrative of The Science. They thought that fat accumulation was caused by eating excess calories like a bathtub overflowing. A scientist from Leiden pointed out a missing detail: if excess calories are constant then weight gain slows down until a weight is reached that correspondents with that constant number of excess calories. Instead what must be happening to explain the rise in obesity is that the amount of excess calories consumed is increasing as well. That may seem self-evident now but once upon a time a scientist from Leiden was vilified for pointing this out and it took a long time before his mistreatment by other scientists was rectified.

On top of that most of what we think is true relies not solely on observation but on induction and deduction so there's always some distance between reality out there and what we think it is. One example would be learning object permanence in childhood and another example would be the flat earth meme that exposes that a lot of us take the scientific stories we're told for granted.
